My experience working with Rywen was seamless across all touchpoints - inspection scheduling, the inspection, contract review, the job itself and follow up check. Roni, Walter, Tony & Miriam make a great team and were all very easy to communicate with. I hope I no longer have rodent issues but if I do (especially after the 1 year warranty), I know who to call to help me again. read more

Roni, Miriam, Axel and his team are awesome. We recently purchased a new home and realized we had roof rats, a lot of them. I had 5 companies come out for a quote. Roni was the only guy to actually put on a hazmat suit and crawl up in our attic for more than 2 seconds. All others peeked inside and quoted us, without even crawling around up there. Their quote came in most reasonable and they were able to schedule us fairly quick. We appreciate their hard work and responsiveness. Thanks guys! read more

Had a great experience with Rywen Insulation Inc, they came out and checked my issue, seemed very knowledgeable and actually cared about my stuff, unlike two previous companies who came out for an estimate. They helped work with me on my final price and budget and was able to getthe work done super fast for rodent proofing. They were always super communicative and friendly. The job has been finished a few weeks now and no further issues. Thanks Rywen I will definitely recommend you all to anyone who needs your services. read more

They gave us a very reasonable quote and comparable with three other companies that we had asked. There were three guys that came to do the job. They were thorough and really did a pretty decent job, from the roof all the way to our crawlspace. They took lots of before and after photos for us to see since we are unable to physically check those tight areas. They checked all our surrounding spaces for any possible entry points for rodents, including under our deck. after a few weeks, they came back to check if there's any more activities and gladly there was one rodent caught on a trap. They set on our crawlspace. So far we have not heard of any activity on both our attic and crawlspace. The owner was very receptive with our request to come out to our property when they need arises. I was so satisfied that I recommend recommended them to my neighbor already. read more

Did some research to get an exterminator for a rat problem at a rental property. Looked at three decent businesses and Rywen had the most reasonable estimate with a longer warranty. The folks we spoke to were friendly and the technician was prompt and thorough. Would use them again although we hope we never have to! read more

This is a long overdue review. Some people might feel this should not be a 5 stars review but I think this deserves more than 5 stars. Long story short, I had bad rat problem in the attic and crawl space. Rywen came for inspection and the quote is very reasonable so I did a rat proofing and replace my old attic insulation with them. They did such a detail job patching holes I could not imagine rat can get through. However, I could still hear rats under my bathtub. Called Rywen and they sent someone out without hesitation. This guy could not find any entry and said it could be the old rat was in there and did get caught by the traps they set. He added new traps and baits. However, after 2 weeks, I could still hear the rats. Call Rywen again and without hesitation, Rywen sent a new crew here. After detail inspection on very wet floor after rain, the crew found a small hole in the screen that rats could get through. They re-did the screen and no more rats after that. I think it is even more important for a company committed to address any problem after the job is done than they always do perfect job. Highly recommended. read more

We found evidence of a few rats in our crawlspace and made a quick call to Rywen. They did amazing work - they redid all of the wire grates on the vents and sealed all cracks around the outside, cleaned everything up and sanitized. Haven't seen a rat since and we love having the 3-year warranty just in case. read more

Had some insulation and abatement work done. They were on time, professional, and I would say their communication was excellent every step of the way. Very easy to work with. read more

I couldn't ask for a smoother, more professional experience. Asked them for an estimate for rodent control (getting rid of them and prevention). Axel was prompt, thorough and clear about what needed to be done. We got a bid quickly and while their bid was not the cheapest, it was quite reasonable and the scope of work was extremely well set out. Plus I was impressed by their 3-yr warranty. The team that showed up was also thorough and so professional (organized, quiet (we work from home), efficient, hard working and friendly). Highly recommended. read more

I contacted Rywen Insulation after our two buildings experienced a massive rodent infestation this winter and early spring. We had hired other rodent control experts in Marin County, previously, but their work was clearly not what we needed, this time. Those experts would come out, seal holes and set traps but do little else. And if the rodents came back in anything more than a month, it was a whole new expense. I was looking for a comprehensive and thorough treatment, and also a business that stood by their work over a longer period of time. Rywen Insulation came through for us (and I believe will continue to come through for us, see below) with flying colors. Rywen came in and over two days with a large team cleaned our buildings of rodent nests and droppings. They sealed all entry holes that had been created by rats, and some others too, with wire mesh. Already this was a bit more than the other rodent experts had done. Rywen then put up a 4 inch wire mesh strip around the base of the insides of our outside wood walls, where they meet our foundation -- this being the #1 location where the rats create their holes in the first place. Our vapor barrier, on the ground under our house, had become dirty, smelly and a place for rats and mice to nest. They replaced it. They then set out a ton of traps. And they disinfected. They will come back next week, and if they find rodents or evidence of them, they will continue to do their work and come back weekly until there is no evidence of them. What had me go with Rywen and take the risk on the high price, compared to the other rodent experts: Should we find rodents in our buildings again, Rywen offers a one-year warranty of "all areas we serviced on the interior of your home. The warranty covers labor, materials, and all rodent-proofing maintenance. If you experience any signs of rodent activity -- such as noises, odors or visible evidence of rodents returning -- simply reach out and we'll return to resolve the issue." Now that is comprehensive and thorough! I'm both impressed and grateful. Our rodent problem was huge. We have heard some mice or rats in the walls, after this treatment. But Rywen is already set to come back to address this. I will update this review should Rywen not come through on their warranty. But I have no reason to doubt that they will come through for us, over the course of the next year. Rywen isn't cheap. Other services may seem more affordable. But we live out in the country with open forest and fields surrounding us. We need something that will last. Rywen's service is exactly what we needed. read more

Roni and his team deserve all the stars! About 3 days before my wife and I were scheduled to have a baby, we heard some curious scurrying coming from our attic. And, of course, the only access point was through our nursery closet. We called Rywen, and sure enough they discovered that rats had made a home in our attic while making a significant mess in the process. Roni worked with us to address the issue on an extremely tight timeline so we could bring our baby back to a happy, rat-free home. The Rywen team was extremely considerate and professional. They made sure to protect the nursery we worked so hard putting together while expertly cleaning, sealing, and ridding our attic of critters. The service was reasonably priced and we're very happy with the results. Thanks so much Roni and team for helping us manage this unexpected curveball before embarking on parenthood :) read more

The Rywen team came to check our house for a mouse issue. They were super prompt and on time and very communicative. Their support team on the back end is also really helpful. read more

We needed some rodent proofing and help with mice / rats under our house. They came out quickly to do the inspection, gave us their recommended course of action and got the job done. They also gave us a extended warranty in case any critters come back in the future. Working with a technicians and also with their office staff has been great. Highly recommend read more

When I was made aware that the insulation underneath my home had been damaged by rodent activity I knew that I needed to have it repaired. I also knew that I would need to find a good exterminator. Long story short it has taken me 3 months to find someone with a reasonable price and expert knowledge to do this time of work. I could not believe it had taken me this long and was extremely frustrated. I came across. Rywen insulation. They came out and went into detail as to what needed to be done. I scheduled the work. Rywen was extremely thorough professional. They showed up on time. They did an excellent job and I'm so glad that I picked this company. They stand behind their work they wanted to make sure I was happy with the work they performed. This company is five stars from me. Their customer service is incredible. I would not hesitate to use them again! This is a top-notch company!!! read more

Axel and his crew did an incredible job removing decades-long accumulation of scrap, old insulation, and God knows what else from our multiple tiny attics and crawl spaces; rodent proofing the entire house; and installing new insulation throughout. He got it done in two days and, despite the significant mess and rough work, kept the interior spaces clean and undamaged. These guys are efficient, knowledgeable, and professional. Would highly recommend! read more

Roni and his team are very Knowledgeable About Rodent proofing your home. Roni is very patient and personable. He did a full inspection (under stairways , Cramp spaces, attic ) of my SF house and informed me of all the access points that need to be covered. I received a reasonable quote, which include Inspection follow ups if needed and a 1 year warranty. He made a difficult problem, go away. He wants to solve your problem to your full satisfaction. I highly recommend his services to anyone who needs it. read more

Miriam had called me shortly after, and helped me reschedule with Roni (the owner) . They were unaware of the situation with their worker being late and "rescheduling" me. They were truly sorry and rebooked me with Roni. I am so glad that we decided to go with them! With the inspection, Roni was already super thorough with checking everywhere. He check all the nicks and cranny's for mouse/ rat droppings. Even checked outside the house for gaps and holes. Roni and his team were through with setting traps, covering gaps and holes. They even cleaned my garage during the process of setting traps (def something I would never be able to do in a million years because my garage was SOO MESSY). Thank you for going above and beyond your services Roni. I highly recommend him and his team, they're super helpful, thorough and professional! I can go on about how great this company is, but I'm sure you guys get the idea! read more

Roni and his team are wonderful!!! He did a fabulous job rodent-proofing and sealing our crawlspace. The job was to lay a vapor barrier over the dirt with a concrete layer above that to stop the critters from burrowing in; fixing some insulation that rodents had been tearing up and making nests with; and sealing all interior and exterior entry points. His work came with a one-year warranty, which is on par with other companies too. In addition to doing excellent work quickly, it was also a very pleasant experience working with Roni because: - He is flexible and communicative, and will text back in a timely manner about the job's details and his arrival times. - He is incredibly fair. When he came to give us our original estimate, he provided three options: one way that we could try to solve the problem ourselves, one medium-level option he could do, and one full-package option he could do. Each option was priced fairly according to each tier. This is how you build trust. I hope to never have to deal with rodent-proofing again, but if I do, I will definitely reach out to Roni -- and you should too! read more

Professional, thorough, and great value to take care of our mice and rat problem. Thank you!

One day I was arriving home and my cat brought in a very alive rat. After 10 minutes of the dogs and cat all chasing the rat while my son laughed hysterically- the cat caught the rat and finished the job. I called Rywen based on their Yelp reviews and they came out the same day to give me a quote on rat proofing the garage. He also offered their insulating service since my kids use the garage as their playroom. Two days later they were back and worked all day. They rat proofed the heck out of my older garage and cleaned up every bit of rat droppings and housing they could find. They sanitize the garage too! They left me two additional traps just in case. Phenomenal experience and amazing quick. Would definitely recommend again! read more

This wonderful company deserves more than 5 stars. They are not only excellent, professional, and detailed in their work; their team members are exceptionally kind. I was dealing with mice in my small living space, and working with a professional company was a big investment for me. I'm so glad I decided to work with Rywen and have no doubt that it was absolutely the right choice. This company did an amazing job of addressing the root causes and resolving the issue, and most of all, treated me in a humanizing way at every step. I also feel that their pricing is fair and that they have great policies in place to ensure that clients are well supported. Much gratitude to Axel for the very helpful initial consultation and for taking the time and care to answer my questions; Walter and the team for the excellent and thorough work; Tony for the incredibly supportive follow up; Miriam for being so kind and making me feel that the company was supporting me throughout the process, and everyone else on the team. You all gave me peace of mind and I'm grateful for all that you do! read more

Starting seeing tiny mice droppings in the garage and reached out to a handful of companies. Of the three that came out, two put on suits and went down to the crawl space to take pictures and explain the process. I ended up going with Roni as he spent the time to explain the entire process and committed to come back as needed. Roni and his team did an amazing job for the main service. They vacuumed the entire crawl space (took 5+ hours), patched all plumbing and outside holes/garage (either with foam, wire or metal), and sanitized the entire area. Once done, they set up 25 traps. In additional, Roni recommended we insulate the garage to keep it slightly cooler and offered a reasonable price to complete that task. They started at 9am and was finishing up at 6:15pm. Since it was late, I felt bad and wanted to rush to let them leave but Roni still took the time to explain all the work done and reinforced a few other areas. While their work was excellent, the part the separates Roni from the rest is that he is the owner, and is meticulous with great attention to detail. He is willing to spend the time to do things right. Key examples were during the process, Roni offered to repaint the panel to the attic as there were light fingerprints, and to fix the broken latch that goes to the crawl space. He just can't stand things not done right. Sure enough, he came back a week later to check on the mice (NONE reported and no droppings) and spent a few hours to put on two coats of paint on the panel and installed a new latch. He also asked me to reach out in 30 days for him to come back again to inspect. I highly recommend Roni / Rywen! read more

Great follow up but took sometime to work out meeting him after initial visits - he's busy but follows through to make sure you're happy

Roni and his large team performed miracles, when cleaning and repairing the rat-caused damage to our crawl-space HVAC ducting. Rats had not only extensively ripped the pink fiberglass insulation off of our ventilation ducts, but had managed to enter the ducts and contaminate them, including dying inside them. What a stench! I learned that when confined (I had placed heavy stones&bricks over the entrances that I discovered) a rat can literally gnaw through the heavy-duty black ABS pipes that lead to the sanitary sewer. (At least they could not gnaw through the iron ones) The amazing Rywen team trapped the remaining (live) rat; removed and replaced all of the ventilation ducting and insulation; removed and replaced the gnawed-through ABS sewage pipes; removed and replaced some leaking iron sewage pipes (threaded-pipe joints were 65 years old); reinforced all crawl-space vents with heavy-duty metal grids; and --- even cut a larger passage in a crawl-space former endwall (12-inch-thick concrete) so that it was easier for me to access under the area where we had extended our bedroom. All for a VERY fair price and including a 3-year warranty. And I should mention that they had previously done similarly-excellent work correcting a rat infestation at my wife's (now-rented) house in Montclair (Oakland hills). read more

I have had evidence of rats/mice in my garage and the insulation in my garage for months. I had gotten rid of several of them but then realized that they were also in the insulation above the house. Bryan (he spells his name differently) came out and did an inspection of the entire house. He took many many pictures so I would know exactly what I was dealing with. (He aslo asked me if I wanted to take a look in the attic area and I said absolutely no, that the pictures were quite enough.) He then told me what he would be able to do for me and gave me a price, not an estimate, which came with a two year warranty. They will also come out to check and replace the traps and also come by if I see any more droppings. Bryan and 4 workers came out last Saturday and spent the entire day removing and replacing all the insulation, removing any rats that they found, sealing all the places the rodents were coming in, cleaning and sanitizing all areas, setting traps & totally cleaning up the entire area before they left. They were amazing and so efficient. I will say, the job cost a bit more than I had been anticipating, but it was worth every cent to know that I would no longer have a rodent problem. I am just thankful that I had them come out before I had found any traces of them in my house. read more

We had a major roof rat infestation in our attic and crawl space. Bryan from RYWEN came out super fast and did a very thorough inspection. I had also priced out two other pest companies but RYWEN was slightly less expensive AND did a much more thorough inspection and quote. The team came out the next week and completed the job in one day in sweltering heat but were so respectful of our house, carefully protecting our floors and closet that had our attic access. They came back two weeks later and confirmed: no more rats! I am so pleased with the service we got from RYWEN. Couldn't recommend them more! read more

This review is long overdue. My gardener first discovered a mouse nest in my front yard in the latter part of 2024 and he promised to come back and spray the nest but he never did. I hired another gardener to spray the mouse nest but by then mice had started entering my home. I don't want Yelpers to think I live in filth but I had a rat infestation in 2019 because I had neighbors that would keep dog food on the porch that attracted rats so rats started entering my home because I have a dog so they would enter my home and eat my dog's food too. The Rodent Proofing company that successfully eliminated rats from my home was the same company I hired to eliminate the mice. After a couple of months the mice were still in my home so I checked Yelp for a Rodent Proofing company that had five star reviews and that's when I decided to contact Rywen because not only did Rywen have a lot of 5 star reviews but their office was located only about two miles from my home. I contacted Rywen and Brayan came out to my home on 01/06/25 for a complimentary inspection. This is where Rywen pulled ahead of the other rodent proofing company I hired because Brayan got "down and dirty" literally and thoroughly inspected BOTH the inside and outside of my home moving appliances like my stove,refrigerator,washer and dryer to check for entry points for mice. On 01/12/25 Rywen sent a team to start the Rodent Proofing process and the team removed the old wire grates that were installed by the former Rodent Proofing company in 2019 and replaced the grates with smaller grates to prevent mice from entering the home,sanitized my kitchen and cleaned mouse droppings and placed down traps. Rywen also checked my crawlspace and entered my attic where the mice were entering through broken tiles in the roof. At one followup appointment a member of the team found twelve LIVE mice alone in the attic. Rywen were thorough and diligent and came out weekly to remove dead rodents and to lay down additional traps. The last time I saw a live mouse in my home was 03/04/25 and a dead mouse in a trap was 03/19/25. I feel like the mice would have been eliminated sooner but I have a big,fat cocker spaniel that got his paw caught in a sticky trap one night so I would pull up the traps in the day but forget to set them down again at night. I want to give a special shout out to Tony Galicia who is worth his weight in gold. Tony was diligent and thorough in removing traps and checking the crawlspace and attic for rodents. My home is now thoroughly rodent free and has been for the past nine weeks which is a blessing because there was a time I would see mice in my home on a daily basis. Oh I forgot to add that for an additional $400.00 Rywen installed a new crawlspace door which I greatly appreciated and which prevented mice from entering the crawlspace. I highly recommend Rywen and have told my neighbor who has a mouse infestation to call them to eliminate the mice from her home. Dealing with mice is traumatizing and I thank Rywen for helping me get my mental health and home back. Also additional shout-out to Miriam who was always excellent in scheduling follow up appointments. read more

Rywen Insulation provided exceptional service and value from providing a complimentary inspection for my rodent and insulation problem in my attic and crawl space to scheduling the job to meticulously competing the job. This is the A team for rodent proofing, attic and crawl space clean up, and insulation needs. I have never seen a team work so well together from Axel providing a complimentary inspection and an estimate to Miriam scheduling the job, to Walter and Axel and their crew completing the job 100% to my satisfaction. They efficient and meticulous in their work. The entire Rywen team went above and beyond my expectations. I highly recommend their services. A highly trust worthy company that delivers on their promise. read more

In the dead of winter, and in the middle of a harrowing health journey, I discovered I had rats in my roof, garage, and basement. For whoever is reading this, can I just tell you how lucky I feel, even now, months later, that I found Axel and the team at Rywen? These people are not only unbelievably effective professionals, they are angels. They worked around me and my condition with so much kindness and grace, and everybody was so lovely, from the team who came to my house, to the folks on the phone. Not a trace of the rodent problem exists anymore. And, not only that, but they replaced a slightly faulty vapor barrier in my basement as well, securing the house in all of these ways at once. I am forever grateful to you all, Rywen team. Five stars all the way!! Thank you. read more

Hired them to set a few traps and pest-proof the house. They were the best price of the 3 quotes I got. I also liked that Roni gave very detailed information at the beginning of the estimation process when they came out to evaluate our home. Very communicative and responsive crew, would definitely hire again. read more

Rywen is, hands down, the very best rodent abatement team among the many we have worked with over the past several years. They are knowledgeable, reliable, hardworking, and effective. Rywen's team has excellent communication and is highly dedicated and professional. We are so grateful to have found Rywen! For several years, we had a far less complex issue of mice sneaking into our porous Victorian. We hired successive local companies to rodent proof and rid us of mice. The teams were generally caring but neither thorough nor competent. Next, we hired one of the big-name players that require an annual contract for bare-bones service from poorly trained technicians. During this expensive contract period, rats moved into our crawl space, finding a perfect nest in our new insulation. The big-name company did nothing to troubleshoot or abate this problem, forcing us to again search for a more effective team. The smaller ones we found were unwilling or unprepared to tackle insulation, especially in a tight crawl space. A more prominent Bay Area company sent their white-glove representative, hoping to whip us into a frenzy, with stories and photos of rats in HVAC systems, attics, and more. That's when we found Rywen. First of all, Rywen specializes in both rodent abatement and insulation. From the first moment Bryan crossed the Bay to do a complimentary assessment of our job, we felt confident we'd finally found the right team. Bryan was clearly qualified both as a serious, studied assessor and as a hands-on worker. Bryan was patient, understanding, and meticulous. He spent an enormous amount of time answering our questions and carefully combing the premises for missed points of entry. His bid was reasonable and fair. Rywen offered flexible terms of payment and a two-year guarantee; notably, they did not pressure us into replacing the insulation. A team of three in hazmat suits--including the owner Roni--came to do the job. They worked hard and smart all day clearing, (eco)sanitizing, and excluding both the crawl space and the entire property. Rywen replaced one rotten crawl-space door and secured both crawl-space doors. When the rats escaped through a hole into the space between properties, Rywen did thorough exclusion work front and back between our homes. On a subsequent visit, Roni brought a device he made to reach deep into the crawl space and plug that hole from within. Roni explained that it would be a process, which we appreciated from our prior, less satisfactory experiences. He left certain interior holes open to lure the rodents into carefully placed traps. This strategy has proven effective. We've been extremely impressed with the ongoing service from Roni, his brother Tony, and other technicians as well as Miriam in the office. Thanks to Rywen, we are turning the corner on this rodent nightmare! We wholeheartedly recommend Rywen for all such needs!!! read more

If I could give 10 stars I would. Roni and his team literally saved my life. We get mice in our house every year around the same time when it's cold out. This year was the worst I have ever seen it. Our home was infested with mice inside and rats in the attic. After Roni and his team came and rodent proofed my home, I haven't seen one rodent since. Nor have I seen any droppings. He was professional, timely,thorough, and took the time to explain everything that was done. I can not thank him enough for the peace of mind my family and I have had since he's come. Not only that, the prices are reasonable with quality work. I think for the first time since we moved in we get to have a rodent free Christmas... Thank you Roni and the entire Rywen team. read more

Roni and the crew were wonderful, there professional and gentlemen. They took there time with my job, explained in detail and answered all additionL questions I had. Roni will do a follow up in a week to see if the critter has been caught. Excellent crew, excellent company, fairly priced... Yes, I would recommend 100% read more

We had a terrible rat infestation in our garage, the worst any exterminator O consulted with had ever seen. Rywen was available on fairly short notice and did an absolutely thorough job. We have had no traces of rats after one visit. Highly recommend. read more

Rywen handled everything so quickly and thoroughly. The initial inspection by Axel found multiple entry points I had missed. He explained the different options for remediation clearly and made it really easy to choose a great price. Scheduling the workdays with Miriam was also easy, and the crew finished on time despite the unusually large amount of ancient insulation that needed to be vacuumed out first. Highly recommended ! read more

Great service. They did a thorough inspection of the property and gave us a good deal. I highly recommend their services.

Roni and his team are truly great. We've had a complicated situation in a unit we are renting out for my mother in law and he's closed out many entry points into the unit as well as come back multiple times to reassess the situation. He always shows up when he says he will and does a thorough job with his team to remove the area of any rodents. Honorable and hardworking team that really sticks to their guarantee. Highly recommend. read more

Roni has done 2 rodent proofing jobs at my building: one for an apartment and another recently for our trash area. The apartment hasn't had mice since he went to work on it. The trash area is a work in progress (and there's only so much you can do for an outdoor area!) His traps have caught a half dozen in the week or so they've been out. He's been great to work with: communicative, timely, and well priced. I certainly recommend! read more

I recently found out that I had rats and mice in the garage and crawlspaces. They also contaminated the insulation in the crawlspaces. As a first time homeowner, this was my first time dealing with rodents directly. I contacted a number of different vendors but ultimately went with Roni since he was super responsive to all my questions whether it was text or late night phone calls. He is just starting up his business and wants to win clients with not only top notch work but also great customer service. He came by with 2 other workers and spend all day thoroughly cleaning, disinfecting, proofing and removing the insulation. They set traps all throughout the crawlspaces and garage. The next night, I saw a large rat inside my house. Not sure if it was trapped inside and found a way to get in. Either way I was alarmed and called Roni immediately. He came by the next day and also thoroughly investigated the interior of the house (didn't do it before since we had no evidence or sightings of rodents inside) and was able to seal off all potential entry points. He also got rid of 6 rats/mice that were caught and rebait the traps. A week and a half later, he came back and to my delight, there were no rodents in the trappings. Total success. His team did an awesome job really securing the entire perimeter of the house. He also guarantees work for 3 years since he stands by his work! He is also helping me with other jobs around the house (duct work, vents). I now have my go to rodent guy (although I hope i don't need to call him again for that) and he will also now be my guy for other types of work. Super reliable, dependable, great quality and will stand by his work. read more

Contacted them for rodent proofing. Roni came to take a look. He gave me a very reasonable estimate. He was very professional and explained the process clearly. I felt confident to give him the business included insulating the attic. They were quick to schedule, flexible with payment arrangements. Very quick to respond when I had questions. Overall a great experience. Have a few more things to get done and will definitely call them up for it. read more
