We live out in the country on a big property, and rodents in our walls and the crawlspace under our house has always been a problem for us. There has been this persistent smell of rodent urine in one of our closets for literally decades, no matter what we have done. Not any more! I could not recommend Rywen Insulation more highly for rodent control work. We've had rodent control people here before, but never at the level that Rywen takes things to. They put in place genuine long-term preventative measures to keep rats and mice out, not just patching holes. And that has made all the difference. No more smell in our under-the-stairs closet! And, I'm not sure if it is always a part of their service, but they offered us a one-year warranty. Rats and mice did return --- probably due to a contractor leaving our crawlspace door open overnight with the lights on, several times (oops). But Rywen took care of the problem immediately, no questions asked and no additional money requested, for the entire year of the warranty. They aren't cheap. But they are soooo worth it. read more

Rywen, is one of the best contractors I have ever used. Their communication is excellent and they did a fine and thorough job dealing with a major rat infestation. After removing the attic insulation, they installed traps and monitor the situation to make sure all of the rodents had exited Very responsive with text and emails Their proposal was a complete standout relative to the other others . Over 40 photos and videos in the attic and around the house showing what needed to be done. Their follow up was very impressive Axel and Miriam were attentive to every detail in this job The warranty on their work was longer than any of the other possibilities I would have no hesitation to hire them again read more

See all

Super thorough with communication, documenting the issues and progress of work with pictures, and scheduling so we were kept in the loop despite being out of town through the whole process. We went with them because their explanations and details in their quotes gave us confidence that they knew what they were doing and were choosing higher quality solutions than other companies for a similar price (e.g., building a foundation-anchored solid outdoor rated door vs. sealing off the crawl space door with just mesh). Glad we went with them. read more

This team was great. I had a large issue, which many complicating factors and the team was responsive, demonstrated attention to detail, and kept commitments made. I'd work with them again. read more

I had a great experience with Rywen Insulation Inc. Miriam W. was professional, responsive, and very helpful throughout the entire process. She took the time to answer my questions. Everything easy from scheduling to completion. The team was punctual, efficient, and did high-quality work. They treated our home with care and left everything clean after the job was finished. We truly appreciated their honesty, excellent communication, and commitment to customer satisfaction. I highly recommend Rywen Insulation Inc. to anyone looking for reliable, professional insulation services. Thank you, Miriam, and the entire team for a job well done! read more

Amazing company...takes care of business and makes sure everything is rodent free. Installed new attic and crawlspace screens and closed all access holes. GREAT at following up as well. Highly recommend!! read more

Rywen Insulation Inc - 2026 New attic insulation and crawlspace encapsulation. - Insulation Installation Near Me - San Leandro, California

Rywen replaced my attic insulation, installed crawlspace insulation, and also do pest proofing for our house. Communication is excellent in terms of progress updates, expectations and recommendations. Work preparation is also excellent: I am very happy that the work area is well sealed off that we can continue to use the rest of the house normally. Work is done exactly on schedule. Overall, highly recommended. read more

Anival and his crew from Rywen Insulation did a great job, worked efficiently and were clean and were a pleasure to communicate with.

Update Today is the 1 month cleaning. Brian and crew came at 9a and leave around 12 noon. 3 hours of cleanup. They were down under the house. It's not an easy job. They might not be able to stand up. I'm impressed. Next one is the 6 months inspection. They take their work very seriously. I'm very happy with their work. I'll recommend them to anybody. Thank you. Great job read more

As many others have mentioned Rywen is a great 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. For the life of me I cannot remember who we used many years ago, but we found out the previous vendor who we paid $$$$ did not do a decent job, so when Rywen came to start working they worked very hard. They had to bring in extra people because the damage from the rodents (insulation) and the amount of proofing they had to do was that much. Again previous company that "rodent proofed" the house did a half a$$ job and thankfully Rywen put in 200% work to make sure our house is ready to fight off the next attack from the rodents. Thank you. Only wish that the warranty was longer. read more

Rywen did a great job removing and replacing our attic insulation. They were very communicative, respectful of our house (great prep work and clean up for minimal mess), and delivered as promised. Axel and his team did a fantastic job on installation day. I would definitely recommend them! read more

Rywen eliminated rodent infestations in the attic and the crawl space under the house. They also cleaned and sealed both areas and fully insulated the attic. Access was very tight in both areas. Their team arrived right on time, were very professional, organized and meticulous and finished the work in just two days. Highest recommendation! Coat was very fair and we're very happy with their work. read more

Very professional Appreciate the assessment and sales process recommend to others for pest control

Great communication and fast work. Guys were friendly and professional. Thanks. That's all I got.

Rywen insulation is the best company for pest control. I have a property in east bay and the tenants are very messy and cause the rodent issue, I hired another pest control company since February 2026, they came on weekly basis and set up traps and stations, it did not help. When I contacted Roni, the boss of Rywen, he immediately sent his team over did the inclusions, sealing the gaps /holes exterior and interior. This morning as their follow up visit, Roni came himself and his team member, they caught the 4 lbs big rodent from the stove. Excellent job, Rywen!! Roni from Rywen is definitely my go to person for any pest control issues. Responsive, Responsible, extensive experience. Thank you Roni! Thanks Rywen team! Great job well done!! read more

Update It's one month inspection after the job was completed. Making appointment was super easy. Tony G came today. Inspected attics, under the house, and crawl space under the heater. Everything is good. Traps didn't catch any mouse/rats. He told me that they'll schedule a deep cleaning on Friday or Saturday. That's a pleasant surprise. Next inspection will be 6 months. I highly recommend this company. read more

The team from Rywen was excellent. Provided free inspection and quote. Clearly explained what the pest removal and rodent proofing project would entail. On the day of the project they arrived on time, kept our home and front lawn clean. Took pictures of the process and final state. Would highly recommend the team. read more

Rywen Insulation Inc - Home prepped to keep other areas clean during Removal and rodent proofing project - Insulation Installation Near Me - San Leandro, California

We had rodents in the ceiling joist between the main floor and basement. Rywen was on site the same day, provided an estimate and was out at our house a few days later adding rodent proofing, traps, and cleared out the old droppings. They came back a week later, cleared the traps (3 mice gone) and set some more. Thorough efficient service and a reasonable price. read more

These guys are pretty good at what they do. Just bought a home and they thoroughly went through and took pictures of what they found. Their estimates were very reasonable and they got a lot of things done! We wanted to "rodent proof" our place as we saw multiple points of entry. I placed a call and many people came out, but none of them were as thorough as Rywen. Overall, it's been a great service and we will keep in contact with them for future needs! read more

High quality service with warranty. I feel stupid for ignoring rat noises for so long. If I had called someone like Rywen earlier and sealed my house, I wouldn't have had to deal with rodent damage to my car and to my insulation. Also learnt the hard way that (1) don't use rat poison because it works it is a bigger mess dealing with dead rats (2) nothing else except for sealing the house actually works. I was very happy with the timeliness and the customer service I received from Rywen. It came at a premium cost but I think it was worth the investment to seal the house from rodents. read more

Requested a visit and quote after hearing noises in the ceiling. Bryan came out and throughly inspected the attic and crawl space and determined there were rodents making their home in the insulation. He provided pictures and gave two detailed quotes. I decided to move forward with Rywen on rodent eradication and to replace my 60 year insulation. The team came in and did their thing. Removed the old insulation, cleaned and installed new insulation and rodent proofed the entire house. The entire team from the initial meeting with Bryan, the workers who completed the job, Tony following up a week later to access the traps and communication with Miriam in customer service was seamless and professional. I highly recommend Rywen! read more

I highly recommend Rywen! We hired them to do a full insulation removal, cleaning, sterilization, rat proofing, and new insulation installation. Everyone there is extremely professional and it's clear that they only deliver the highest quality. The communication was great. They were on time and did excellent work. I feel like they were the best value vs the other quote we received. read more

Great Customer service . Quality workmanship and communication from the installers . Provided photos of before and after

Great company, great staff, and truly professional service. From the initial inspection to completing the job on time, everyone at Rywen was professional and courteous. After comparing several quotes, I chose Rywen for insulation replacement and rodent proofing for my two-story home. While their pricing wasn't the cheapest, the value you get from the quality of their work is outstanding. The inspector conducted a thorough evaluation and explained everything clearly and patiently. The on-site crew arrived on time and worked tirelessly throughout the project. After finishing, they carefully inspected the property and sealed all potential entry points with mesh wire. They also used high-quality, brand-name batt insulation, which is far superior to blown-in insulation. A follow-up visit a week later confirmed that there was no more rodent activity. I highly recommend Rywen Insulation to any homeowner in need of insulation replacement or rodent-proofing services. Keep up the great work! read more

I have been very satisfied with Rywen Insulation so far. They recently sealed my house and I'm hopeful it will do the trick and keep the rats away. Everyone I've worked with has been helpful, responsive, friendly, and professional. They gave me options that accommodated my timing and budget, and even when a small issue came up, they addressed it promptly and professionally. I recommend this business. read more

Reached out for pest control and ultimately got new insulation as well. Quick and thorough response. Great price too.

Best prices after searching around and getting a lot of quotes. efficient and responsive.

I had a great experience having Rywen and their crew coming out for an attic insulation replacement and rodent service. They finished the job on time and very thoroughly checked and sealed internal and external loopholes for rodents to come in/out. Great work quality. read more

Rywen Insulation are true professionals, from quote to completion. We received 4 quotes, and Axel from Rywen was by far the most thorough. He even came back to inspect another area, and give us various options. The crew did an incredible job on day 1: sealing the house while vacuuming out the old insulation and then sealing and sanitizing every nook and cranny. On day 2, they installed the new insulation. They again sealed areas to prevent debris from entering the house. The crew were suited up with protective gear and were very skilled at their jobs. I would highly recommend Rywen Insulation. read more

Every staff member I worked with was excellent at Rywen Insulation, Inc. I enjoyed meeting with Roni when he listened to me so patiently and provided a quote outlining the exact work I requested to be done. The entire crew that came out to my house to do the work were helpful and easy to work with. Every staff member was on time and pleasant and respectful. I met with Anthony (Toni) yesterday and he checked all of the rodent traps and the vapor/moisture barrier installation work. Anthony and Roni and the entire crew and Jeiry R., the leader of the crew was excellent to work with during the 8 hour day their crew spent working at my house. I recommend Rywen Insulation highly and I plan to send referrals to Rywen in the future. Thank You, Tammy Goyette Homeowner where insulation and a vapor/moisture barrier was installed and the attic, crawl space and other areas were rodent proofed. read more

Very professional In presentation and quality of work. Very thorough. Rat-proofed home inside and out.

Rywen did a great job helping my house with rodent problems back in July. Shoutout to the crew that came to the rescue during the hottest two days in July. It was 95 degrees, and the attic and crawl spaces were unbearably hot. They came out and got the job done. I started hearing rodent noises in the walls a couple weeks prior, and the smell of death from underneath the kitchen was unbearable. I had several teams come out for inspections. Rywen's quote wasn't the cheapest of the bunch, but it was the best overall package. They walked me through problems in the attic and the crawl spaces, and showed pictures of droppings, chewed up wires and insulations, entry points, and various problem areas. They were responsive with my followup questions and concerns. I ended up opted for replacing attic insulations, in addition to cleanup services. Other observations: * the horrible smell from underneath the kitchen went away days after the cleanup. I think it takes time for the odor to completely dispel. * I heard noises for a couple months after the installation, and initially thought the problem came back; but it turns out it's house noise -- likely due to the installations expanding and weather changes. (side note to Roni - if you still have the after pictures, please send them over. I can post here. I forgot to followup back in July.) read more

very warm and friendly people, both at front desk and service. very prompt service and it achieved its purpose

Highly recommended for insulating my attic with foam and subfloor with bats. They redid the recent job of an unlicensed contractor who ripped me off. If I had checked the contractor's license bureau, read the negative reviews on Yelp and ignored its' stars and '"erified license", the job would have been done right the first time and for less. Comparing legitimate companies, Rywen was not the cheapest, but their inspection was more thorough so I chose them. Noise wise, their equipment compared to the unlicensed one was definitely better. Phone ocalls were promptly returned and Miriam spent time helping me download the many before and after photos. Obviously, the "boss" uses the photos to check the work, and I received a call telling me they were coming back to make a few corrections that I wouldn't have noticed. They want to do a job and I believe they succeed. read more

They were very professional, clear about the work they would perform. On the day of the job, they came prepared to tackle the problem and finished the job cleanly. It was easy to schedule a follow up as well read more

We called to have an outdoor storage bin with a rodent issue hauled away. Axel showed up early within the scheduled timeframe and took the bin away. He also conducted a thorough interior and exterior inspection of the property at no charge. Bottom line, we appreciated Axel's amiable, courteous and knowledgeable consultation and service. We look forward to Rywen back to take on a full treatment project. read more

It is a rare company these days that provides old time, first class service and work product. Rywen is one of those companies. Rywen was contracted to remove, decontaminate, and reinstall insulation, repair damaged duct work, exclude and exterminate rodents and install a vapor barrier. The project took five, full days of hard work. Axel Galicia was the estimator and also the project manager throughout. His estimation was spot on and the only addition was the replacement of two air ducts which could not be accessed during his original estimation and inspection. The projects were documented with before and after photos. All of the crew members were respectful and careful of the property. Axel was able to recommend other repair work which was needed for plumbing and roofing. These items were repaired before the new installation and duct were installed. I solicited bids from five other companies. These companies ranged from large to small firms. Rywen's quote was thorough, explanatory, contained quality materials and reasonable. They were not the least expensive. Nor were they the most expensive. They were the most comprehensive. They are licensed, bonded and insured. They are a local family company. And, the family works on the projects, so they are particularly invested in delivering excellent results and quality work. Give them a call!!! read more

Had a great experience with Rywen Insulation. I had a serious issue with rodents. Called and received an immediate response from Rywen. The owner (Roni Galicia) came out first to take photos and videos of the issues and he went over everything with me to show me what was going on. They sent out their team the next day on Saturday and had the basement totally cleaned up and secured by the end of the day. They set up traps and came back a few days later to follow up and make sure everything was taken care of properly. They are full service, I had a water pipe leak and a problem with the toilet seal leaking and they took care of that also (along with replacing insulation, repairing door entries, etc. They are thorough and Roni is a very responsible person who is a good communicator and wants to make sure the job gets done right. You're in good hands with this company. Also, the lady in the office, Miriam, does a great job following up with you in a timely manner. Price was very reasonable. Highly recommend this company. read more

They did a good job and gave us one year warranty. I would definity will use them again in the future.

Really wonderful service - responsive, works fast, solves the problem. Worked with them 2x already.
