I contacted several attic and rodent companies before choosing Attical, and I'm very glad I went with them. What stood out most was how thorough they were. Unlike some other companies that focused only on the attic, Attical inspected the entire property, including the attic, crawlspace, garage, exterior walls, roofline, and other potential rodent entry points. They identified and sealed areas that other companies either overlooked or never mentioned. Their pricing was also very competitive. During the quoting process, some companies adjusted their pricing based on estimated labor time, crew size, or changing measurements. Attical, on the other hand, honored their proposal and focused on getting the job done properly rather than finding reasons to increase the price later. Throughout the project, they delivered exactly what they promised: insulation removal, sanitation, rodent proofing, air sealing, duct repairs, trap monitoring, and new insulation installation. The crew was professional, hardworking, and took the time to explain the process and answer questions along the way. Overall, I felt that they genuinely cared about solving the problem correctly instead of simply completing another job. I would highly recommend Attical to anyone looking for attic insulation, rodent proofing, or attic restoration services. read more

AttiCal did an outstanding job with our pest control and attic cleanup. Angel and team thoroughly cleaned the entire attic, removed all evidence of rodent activity, and sealed potential entry points to keep new rodents from getting in. What really stood out was their commitment after the initial service. They followed up to make sure everything was working as expected and that no new rodents had returned. It's clear they genuinely care about doing the job right, not just completing a one-time service. The crew was professional, punctual, and left everything clean. If you're looking for a company that stands behind its work and delivers lasting results, I highly recommend AttiCal! read more

Professional, efficient, and thorough. Adrian explained everything during the initial estimate, and the crew made sure no detail was missed during the installation. Plus, the 4-year warranty provides great peace of mind. read more

David and Angel and the rest of the crew are just amazing. They go above and beyond in every way. They respond immediately to every call. They do the most thorough competent job with more care and detail than other companies I interviewed. I wanted special attic fans and they were happy to accommodate and do the custom install that was needed. Also, the cost is extremely fair for the product and services they provide. Most highly reccomended! read more

#knowledge - 5/5 #service - 5/5 #value - 5/5 #context - we suddenly found out we had rodents because there was a lot of droppings in the attic. Adrian came out quickly to perform an inspection. #like - Adrian was incredibly friendly and personable. He did not try to push any services onto us. Instead he was very informative and flexible. He was able to schedule on short notice and his team was there in a couple of days to do the work. The workers cleaned up the attic real well and they closed off openings they found. The owner, David, was also responsive which is really important to me as a customer! read more

The service provided was excellent. The team was very thorough in cleaning and sealing off any rodent from coming into the house. The price was competitive and well worth it. read more

David's team is amazing and knowledgeable. Thank you for all the hard work and wonderful job your team had done. The staff are responsible and get the job done fast. The price is reasonable and including 4 years warranty which is great. They cleaned all the droppings and sanitized everywhere. David tried his best to accommodate what I need. The service is great. Highly recommend to use their service. read more

We had a bad smell coming out of one of our vents and we couldn't figure out where it was coming from when we checked. I needed to call professionals and David and his team were quick to do the initial review and estimate of the issue. They showed up on time, went into the crawl space, took photos, and had a quick discussion about some recommended options. From there we got the quotes, signed off on the option we wanted, and they came and fixed everything up the next work day. I sent out a request for service on Friday, they came Saturday, got a contract on Saturday, and the work was completed on Monday. The team was really professional and easy to work with. We ended up needing to replace insulation, get the area sanitized, sealed up to prevent future critters from moving in, and also opted to replace the HVAC ducts since rats had chewed through some of that as well. Fair price for good work. I hope I never have to call them for this type of service again, but if I do, I wouldn't hesitate to ask for their help. read more

As a real estate broker and property manager for the last 37+ years, I have used many contractors and service people, including other rodent/pest companies. Angel is very thorough and has done a great job for me at multiple properties in the past. AttiCal is on top of my list for their excellent service, timely execution and reasonable pricing. read more

Very professional crew and competitive pricing! They showed up on time, were courteous, communicated well and took care of business all day aside from lunch break. They sealed many difficult to reach spots in the attic, eves, roof returns etc. and around the crawl space and around pipes, with 1/4" galvanized steel mesh (sometimes added concrete where needed). They produced before and after pictures of their work and set a bunch of traps that they will check in two weeks. I was pleased. read more

They did great! Service was fast and efficient. Highly recommended! I never knew there were specialist in rodents and insulation but so glad there are. read more

I couldn't be more impressed with the work Attical did on my crawl space and attic. They handled everything--complete clean up, new insulation installation, asbestos removal, ducting work, and moisture barrier/sanitization to eliminate rat urine odor. The transformation is incredible! What really sets Attical apart is their professionalism and customer service. The entire team was exceptionally polite and genuinely willing to work around my needs and schedule. They took complete ownership of the project and kept me informed every step of the way. They arrived on time every day and treated my home with tremendous respect, which meant so much to me. It's rare to find a company that combines technical expertise with such a strong commitment to customer satisfaction. If you need crawl space or attic work done, I highly recommend Attical without hesitation. They've earned every one of these five stars! read more

Did attic cleaning, rodent proof and insulation installation. Quality work for reasonable costs. I would hire them again in the future.

Attical has been so thorough and responsive - truly exceptional service. Any rodent issue you have, they should be your first call.

Very helpful and prompt company. David and his team came out asap when I had a rodent problem. They were very good about honoring their warranty and coming back regularly to check for rodents. They provided pictures of all their work and recommendation areas. I am very happy with this company and would recommend them to anybody that has a rodent problem read more

We discovered a water leak in our home's crawl space about a month and a half ago. Due to the water damage, we had to go through crawl space water damage cleaning, plumbing repair with pipe replacement, duct replacement, and rodent prevention work. We received quotes from four different companies, and among them, Attical Insulation and Rodents clearly stood out. They were by far the most honest, thorough, responsive, and reasonably priced. Adrian, who provided the estimate, was very detailed and attentive in checking all the issues in our home. The estimate he gave us seemed honest and fair. Even after requesting multiple revised quotes for comparison, he remained kind and quick to respond every time. I also want to thank David and his team, who actually carried out the work. They were punctual, worked efficiently and carefully, and made sure dust didn't enter the home during the process. For rodent prevention, they replaced or repaired even the smallest openings and even patched the garage entrance with cement. Their attention to detail and follow-up service were excellent. Huge thanks to David and his team! Even after the water damage cleanup, some insects remained, so the water damage company revisited our home the same evening the Attical team completed their work and reapplied sanitizer. While here, they asked me who had replaced the air ducts. I told them it was Attical Insulation and Rodents in Fremont, and they said it looked like the work was done very well. Coming from a completely unrelated professional, that compliment gave me even more confidence in the quality of Attical's work--even if I can't physically see everything they did behind the scenes. If anyone asks me for a recommendation, I will 1000% recommend them without hesitation! Thank you again, David! read more

I cannot rave enough about this company! The most important thing is results and I've had no problem a year out since they've done the work at my home. They handled redoing our ductwork and completely eradicated a persistent rat problem. Their professionalism, kindness, and integrity are truly unmatched. What impressed me also was how seriously they honor their warranty. Not once did they make me feel guilty for calling with questions or concerns. In fact, they were so compassionate that they came out right before I delivered my baby--simply to give me peace of mind--even though there wasn't any confirmed activity. That level of care is rare, and I'll never forget it. Every technician who came to our home was respectful, thorough, and genuinely invested in making sure everything was perfect. It's such a relief to work with a company you can trust completely, and I recommend them wholeheartedly to anyone needing ductwork or pest control. If you want exceptional work backed by honest people who truly care, this is the team to call! read more

Was looking to have a simple mouse extermination. I worked with someone to schedule an appointment for the next day. 30 minutes before the appointment, they called and said they probably won't be able to warranty the service they said they could. Then they said they couldn't make the original appointment time. The expected cost of the service as well was going to be over $2,000 for basic mice removal, which seems high. 1 star on so many accounts. I'd go elsewhere and save a bunch of time. read more

David and his team did an amazing job at cleaning up a huge rat infestation in the attic about four years ago at a significantly discounted price. read more

Attical Insulation and Rodents - David's team getting ready. - Insulation Installation Near Me

We had some rats in our attic late last year. The insulation was pretty new; we had replaced it in 2019 and had it rodent proofed but a couple of rats had made their way back in. I wanted to rat proof again and clean up the damaged area. I called around, and one place told me they had to replace the entire insulation again, otherwise the rats would come back. But David was able to clean up the messy area and add more rat proofing. He did this back in November 2024 and I haven't heard the rats since. Great work!! read more

They were fantastic to work with from the start. They thoroughly evaluated the situation in the initial visit, donning protective clothing to discover all the openings, evidence of the rats etc. They took pictures to illustrate some of the issues.Their price was competitive and they brought in a big crew within a few days who sealed everything up, much more thoroughly than a previous company. Before they came we had rats in our house, attic and basement and since they left nearly a year ago we haven't had a single problem. read more

Quick response and communication was good. Be patient. They are busy, but very honest and told me the droppings were old and I did not need their services. read more

David and his team are incredible, and I highly recommend them! We initially reached out because we heard some sounds in our attic and knew we had a rat problem - they were extremely responsive, immediately scheduled some time to check-in and provided a quote very quickly. They came by to set up traps and close all the openings around the house. They built a custom crawl space door that fit perfectly - David's team really goes above and beyond to provide the best service. Further, their attention to detail is unmatched. The mesh covers are done in a way that is not a complete eye sore (the way I've seen that other rodent and insulation service providers do when its just a goopy ugly mess on the side of your house), and it's effective AND still looks good. Most importantly, they're very responsive about questions around insulation. Our home is now rodent free, and we're so happy with choosing Attical!! Don't be deterred by the number of reviews. David's team has decades of years of experience (and it really shows in their excellence), and they started their own new business. read more

Adrian came and showed me potential entry points for the rodents, and gave me a competitive quote. Then David and his team came and cleared a nasty mice infestation in my pantry; blocked off all the entrances to the outside from the house, crawlspace, and attic; and removed and replaced the insulation in the attic that rats had been tunneling through and leaving a lot of feces. After a few weeks of laying out traps to catch the remaining rodents stuck inside, there's no more scratching sounds coming from my attic or mice running around my kitchen. Very satisfied with services rendered. read more

Great service! Not many places offer mouse removal, and they responded so quickly. Fast, professional, and really put my mind at ease. Highly recommend! read more

The attical crew was efficient professional and responsive. They did above and beyond work while doing everything I asked including fixing the duct that rodents damaged, leaving zero mess, and they did it all for a competitive price. I would recommend them to anyone who is looking to do the insulation replacement and rodent sealing. I had a shake roof replaced in October and the attic required me to wear an n95 because it was so dirty and dusty. Additionally we had rats due to the roofing company not dealing the holes well so the attical team did an excellent job on all fronts. read more

First to respond on my project and free inspection. Not only disinfected, cleaned up, rodent proofed but discovered other issues in the crawlspace under the house that needed to be repaired (like a loose air duct). They took photos, gave me couple options to remedy and were responsive to feedback and any concerns, plus we get a 2yr warranty guarantee for the work they did and will return to check the traps. David and Adrian are great, highly recommend! read more

David exemplifies what it means to go above and beyond on delivering results. I reached out to him after hearing some odor and noises coming from my HVAC - we suspected a rat had somehow made its way into the system. David responded in a matter of minutes and managed to come out to give a quote. Here's where things start to shine - David found a skunk that had made its way into my crawlspace, leaving fecal matter and urine close to my HVAC unit. Most other businesses subsequently told us to figure it out on our own. David didn't leave us out to dry. We paid David to: - Remove the skunk - Rodent proof the home - Set up rodent traps - Clean and check attic for rodent activity - Sanitize the affected portion of the HVAC system - Clean and remove droppings and insulation Going above and beyond: - David even offered to build a door for easier access into my crawlspace for free. I provided the materials and he got to work. - David documented every fix and rodent vulnerability - He even agreed to remove the weighty and significant junk in my crawlspace - He removed some cabling from the attic that we had issues removing ourselves - He even provided insulation tape to the air return vent (despite the vent not having it originally) David's ethos and attention to detail really encouraged me to write this review. You can't go wrong with this business. read more

David and his team did a fantastic job with our attics (we have 3 separate small attics). They conducted the inspection thoroughly and were punctual. They showed me pictures of the entry points for rodents in my attics and the damage done to the insulation. They promptly gave me a detailed quote. I appreciate that they did not try to upsell me to replace all my insulation, they only planned to replace the parts that were damaged. His team arrived on schedule and did all the work planned in 1 day. They covered all my belongings in plastic so nothing was damaged or dirtied. They showed me pictures afterwards of all the sealed holes, traps, and new insulation. David recommended a follow up after 10 days to check the traps and sealed holes. This was also promptly scheduled via text. His team member checked all our attics and showed me pictures. All the seals were intact and no rats had gotten in to the attic traps, so we were very happy. There's a two-year warranty so if we have any issues we can call them. I highly recommend David and his team if you have a rodent problem. They were very professional and thorough. read more

We needed insulation replaced and rodent proofing of the property due to a rodent problem. David and his team did an excellent job not only replacing insulation, but also sealing all entry points in the attic. They have been honoring the warranty and have come a few times to check and tighten entry points. read more

A broken kitchen drain pipe led to a rat and mice infestation in the crawl space of our house.i called Attica and Angel came on time for the estimate. David and his crew arrived on time and finished the entire crawl space clean out and rat proofing in one day. Fantastic work and the crawl space was totally devoid of any debris. Cannot thank David and his team enough for their great work. Their prices were reasonable and at market. read more

They were nice but never sent me a quote for the work, even after I asked twice, was ignored both times. It is frustrating that I took off work to arrange to meet them then to have to do it all over again with another company. If they didn't want the job or weren't qualified I would have appreciated that being communicated. read more

We were recently dealing with a small mouse issue in one of our bedrooms and called Attical Insulation & Rodents for help. David responded quickly and came out with his team to inspect our crawl space. They immediately found several holes and even located additional holes on the roof. After a thorough inspection of the entire house, David gave us a very reasonable quote to fix the holes, add protection, clean our highly contaminated crawl space and re-wrap all air ducts. Having had unsatisfactory experiences with other rodent-proof companies in the past, we were impressed with David's professionalism and decided to hire them for the job. The price they gave us, which included a multi-task discount, was even lower than we had anticipated with fewer tasks, which was amazing! David and his team returned a few days later and spent an entire day working. Afterward, our crawl space was spotless and free of any odors. During the process, David also pointed out mouse droppings and dead rodents in the attic, as well as a fire hazard with the range hood exhaust pipe. Instead of pressuring us to hire them for these repairs, David simply recommended we get them fixed soon by anyone. We appreciated the honesty and asked for a quote from them. Their price was significantly better than the market average, so we decided to proceed with them. They returned soon after and completed the job, leaving our attic clean with fresh insulation. They even repaired insulation in another small attic for free. Both my wife and I are extremely satisfied with their work, and they provided a 2-year warranty as well. David's team also followed up to ensure no more mice had returned - and we haven't seen a single one since! We feel that the money we spent was more than worth it and would highly recommend David and his team for rodent-proofing, cleaning, and insulation services. If I could give them 6 stars, I would! read more

Very professional, very prompt, took the initiative to close all rat access points, replaced compromised insulation, did all the extras. Best rat company I have dealt with in over 50 years , and I am in the real estate business all that time. read more

Had a rodent problem and initially used a pest control company to diagnose and set traps. The pest control technician reported to us that the attic had lots of accumulated mice feces (yeech) and likely gaps under the insulation - he suggested that we needed to hire an "attic restoration company" What's that, I thought. Had never heard of this service. But when I did a YELP search I found dozens of companies that did this. Called three of them and two came out quickly to provide quotes (the third company never responded...) Both quotes were very similar in price. It seems the quote is largely based on sq footage, and the scope of service is pretty standard. What set apart Attical and David Lozano were three things: communication, willingness to customize, and clarity-detail of quote and services to be performed. Communication - my contact was David and he always responded promptly to my text messages. We traded messages several times as o had to reschedule the date. Willingness to customize - I had a plywood landing area in my attic. Just about 100 sq ft. The other company said I could buy the plywood and they would bring it up to the attic, but then I needed to screw down the boards. Huh? Attical said they would go to HD and buy the wood and install. I just had to pay for the material. Makes much more sense! Detailed quote - Attical provided a step by step list of what they planned to do, and since I had no experience with this service before asked each company to explain before I made a decision. David took his time explaining and I felt I had a much better understanding after talking with him One more note - after the service there was some new cracks in the drywall from people walking on the attic rafters. This is a house built in 1956. A bathroom door no longer closed correctly. Not big stuff but I don't have tools. Attical came out two weeks later and did the repairs. Easy enuf, but the attitude was much appreciated I would highly recommend read more

David, Adrian, and their team was amazing. When we discovered we had issues with rats in our attic, many companies refused to work with us due to our Spanish tile roofing. Roofing companies wanted to charge us for an entire new roof! Crazy! But David and his team at Attical came in, set traps, and rodent-proofed our entire attic. They cleaned up years of rodent droppings and left our attic smelling like fresh and new. They even covered our floor in plastic to ensure that no dirt or insulation tracked into the house. Very clean. They also gave us a hefty warranty and a number to call if we hear any traps go off. They are willing to come back and seal any spots that rodents create after the proofing. They are a team that knows the struggles of rodent proofing in the bay area, and they take a ton of before and after pictures to show you just how much they do. Amazing work. Done in just a few hours. I would call them again in a heartbeat! read more

The team at Attical Insulation and Rodents is awesome. I have had an issue with attic rats for the last two months. After having several companies come by to try to figure out the entry point(s) the rats are accessing my home, Jesus came out and was able to locate the entry points. Jesus then put me in touch with Adrian and they were able to work within my budget to set up a time to come out and rodent proof the home. On the day of the appointment, Julio came out and didnt an outstanding job with closing up the entry points and even going to the extent to take care of some wires that the rats started to chew. Thank you Attical Insulation and Rodents team to be so knowledge and caring for your customers, I am here to refer anyone who is dealing with a rodent problem to you guys anytime! Be blessed! read more

David and his team are great. Their persistence and commitment to completing the job is 10 of 10 - truly impressive. What did we have them do with our house in Los Altos? 1) Crawlspace cleaned, sprayed to remove rat pheromones, and rodent-proofed. 2) Remove blown in insulation in attic. 3) Thoroughly clean, spray, and rodent proof attic. 4) Install new batten style insulation. The rats love our house and they came back. David and his team had to come out three more times to find out where these critters were digging holes to get back in. I felt bad every time I asked his team to come back and David was always cheerful and said "no problem, we will be out there to fix it." Just fantastic customer service. read more
