Constraction reviews in San Leandro, California

These guys are great and stand by their work. A year ago, they fixed our rodent problem and installed new ductwork under the house. Today, one year later, we asked them to come out to make sure everything under the house was still pest-free. They came by with no hassle and reset the original traps with new bait.

EXCELLENT EXPERIENCE- They took a load off my mind. They arrived on time, did a complete inspection with pics, were reasonably priced, Cleaned and sanitized my basement, repaired nasty insulation, fixed all my vent covers, left it cleaner than it has ever been. I can not give them enough praise!

I have been working with Rywen Pest control to solve the problem of rats in my crawl space. From the moment that Roni came out to evaluate my home and its problem areas, I appreciated his thoughtfulness, the depth he brought to the problem, his willingness to listen to my concerns and his inventiveness when considering different solutions. I like that the business is family run and that Roni has extensive experience in pest control. In all interactions, he was timely in his responses and his scheduling. He kept to the schedule.
His team was careful and noticed additional problem areas as they began to rat proof every opening to the crawl space. They were easy to communicate with and did a good job cleaning up the space and after their work.
Because we had found evidence of tunnels, we decided to go with a full cement rat slab for two sub-floor areas. In both areas, they removed rocks and other obstructions, put down a moisture barrier and placed rebar over the barrier. Pouring the rat slab was difficult, because the access points were on the back of the house, making it very challenging to bring in a cement pump. They hand-carried and hand poured the cement over my subfloor to provide the necessary protection. The finished product makes me happy to step back into that space. The second sub-floor area was much more challenging than the first with some parts barely having a foot of clearance. Roni was not satisfied with the first pouring of the rat-slab because there was some roughness and a few gaps near the joist footings in the very narrow sections. He brought the team in a second time, headed by his brother Axel, to perfect the job.
As well as the rat proofing, Roni noticed a few other areas, such as painting touch ups and cracks in the sidewalk that they were able to fix.
In all work, I felt like Roni, Axel and the rest of the team treated my home as what they would like to see in their own homes. Their work was detailed and they should be proud of the jobs they did. I am indebted to their thoroughness and I would certainly use them again. I also appreciate that they are a family run business.

I was very happy with Rywen’s customer service, communication, and attention to quality. I was especially impressed with their suggestions, for example, ensuring we got the desired thickness of insulation in the attic, overall, plus providing my desired amount of future access. To me, it felt like the company has a consistent attitude of going over and above and that’s rare. Thanks!

We used Rywen insulation for rodent infestation. They did a great job, appeared on time, they were very polite and professional and did a thorough clean up. They also proofed the whole house against any potential future intrusion. They are great communicators, keeping you in the loop about arrival time, procedure, follow up... We are very happy with their services and intend to use them in the future.

Walter did a very thorough follow up visit. He did a great job in finding out how rodents were entering our house. He fixed the areas and cleaned up all areas affected. I would highly recommend Rywen They guarantee their work. They do a great job!

Amazing job and customer service. I highly recommend. I have another rodent problem in a 4 bedroom home and Rywen was so prompt in getting me a bid and then scheduling the work. Meriam, in the office, is amazing and so efficient.

We previously had a rodent issue in the attic and crawlspace of a fourplex and now everything is clean and rodent proof.

Thank you sooo much Rywen!

Outstanding experience. Supervisor was Anibal and he was unfailingly courteous, effective, and communicated clearly and well. Excellent team, excellent work, and a very good experience for us. They cleaned and sealed our attic and crawl space and insulated our attic.

Really loved working with Rywen from the initial quote to getting our attic insulation removed and replaced. Every person who came into our home was very respectful, kind and thorough. Would definitely work with them again.

I wish I had snapped photos during the process to show you how clean and sanitary and professionally this company works. The crew arrived at exactly the right time as promised and lined their trail with either paper and plastic to seal off rooms. They went into my attic and found that the previous company had not done what they were supposed to have done And took photographs of it for me. I’ll deal with that at another time. They sucked every bit of old insulation out of my roof and it was spotlessly cleaned and sanitized , then they installed new insulation and I have over 50 recessed lights and they carefully enclosed each one and sealed with foam. every screen was replaced to make sure that no rodents could enter through my attic. Under my home, they dug next to my foundation 14 inches deep to be sure that no more rodents could tunnel under the foundation they installed wire and bolted it to the foundation. My project was done with scrupulous attention to detail, and Axel will return to my home next week to pick up the traps that were left in the event any rodents were captured in the house during the sealing. The communication with Rywen is exceptional. As for Price, it is fair for the quality of work that they do. I can’t wait to sleep through the night without hearing rats, digging under my house! I feel this is a tremendous upgrade to my home, and I have terminated my monthly rodent contract contract, which did absolutely nothing for controlling rodents!

The entire team did great work. We really like the work. Good communication, detail of work and timely completion. Would really recommend Rywen insulation inc to other people. Now we can store lot of stuff in attic for which they did a nice plywood flooring, insulation , plus all electrical lighting in attic, and attic ladder. Great team!

Rywen added blown-in insulation to my attic. When I first contacted Rywen, I was speaking to a live person right away, and she took my request details and got back to me promptly with an installation schedule. The 3-men team showed up on time, prepared the areas thoroughly like a hazmat zone, went to the attic and leveled out the existing insulation, added new material, and completed with a thorough clean-up. When done, the place looked as if nothing happened. The team was professional, respectful, and efficient. Job well done. I would recommend Rywen for my friends and family any time.

Rywen Insulation is an excellent company! Every step of the way was thoroughly explained and completed in a professional manner. Axel did the initial inspection, Walter led his team with the job of replacing insulation, disinfecting and rodent proofing and Roni was super helpful with an electrical issue I had. Everyone at the company was pleasant, knowledgeable and patient with my questions. I highly recommend them!

My house got a rodent problem and damaged my attic badly. I called multiple companies to do the attic cleaning and rodent proofing. Axel from Rywen gave me the most comparative price, his prompt response to my request impressed me a lot. And the guys who came are very professional! They covered and protected my other living area well. It turned out that the attic was worse than the first inspection. They spent more than expected hours on cleaning the attic carefully to make sure everything looks good. I am so happy to see the contrast before and after the cleaning. More importantly, Axel did thorough rodent proofing and gave me a warranty for their treatment. It is a nightmare to have rodents in your house! It is greatly critical to clean your attic once you have those rodents, thinking about those debirs and droppings that will harm your health. Even though you don't have a rodent problem, it also adds layers of comforts to your living after new insulation! I definitely will use them again in my another house. This is a highly trustworthy company!

On Wednesday Axel walked me through the whole process a couple of times. He immediately won my confidence and I signed up to get the job done by Rywen. I could not wait for the work to start.

The team of workers arrived Monday morning as per agreement - they displayed nothing but professionalism as they prepped the house with paper walkway and plastic tunnel leading to the ceiling opening. Like clockwork the old insulation was sucked out and new insulation laid down piece by piece and secured. In the unfinished basement, where rat infestation was evident, all the junk piled up over more than three decades was removed and hauled away. The foundation and walls cracks were sealed to keep mice and rats from entering the premises. The kitchen was thoroughly inspected for cracks in the walls and cabinetry. Where necessary, cracks were treated with the application of sealant and or with wire mash.

I am confident I made the right decision to go with Rywen. I highly recommend them.

We have had a very good experience with Rywen Insulation. Axel did a thorough free inspection and identified the places that the rats were entering. The crew was on time and removed all the old insulation and sealed all the entry points. Traps were set. They worked through the pouring rain. They made sure our house was protected. They did a good job cleaning up. The follow up inspection with Tony was very professional. He took his time to explain there was no evidence of any rats in the attic and removed a trap in the crawl space. Rywen will install new insulation when we complete the replacement of the knob and tube wiring. We had a slight miscommunication, but Roni quickly took care of it. We certainly recommend them.

Our home had unwanted visitors (rodents) in the crawlspace and attic. The Rywen Insulation team came and made sure to close any holes to deter pests from getting in. Furthermore, they removed and replaced the old insulation, and cleaned the attic and crawlspace from and rodent droppings. The entire work was done in a day. This team checked and patched any holes from the inside and did a full inspection of the exterior of the house, including the roof, to ensure all possible entries were sealed. The first night, I heard and saw a large rat trying to desperately get back in, but I think it gave up and moved on. I now get uninterrupted sleep at night and no longer hear scratching sounds or movement in the attic. Moreover, their customer service was excellent. This is a super responsive team that earned my trust by being quick to respond to any questions I had. For the pricing, this company charged me slightly higher than the 2 other companies I received proposals from, but I still believe the cost was reasonable for the great work that they do. One of the other companies only patched holes within reach and let me know they would not go on the roof, and I would need to hire someone else for that work, while Rywen Inc made sure that if the holes could not be reached from the inside, they would be patched from the outside, even if it included going on the roof. Thank you to Brayan, Walter, and the team for the great service.

Services I got were attic clean up, insulation replacement, crawlspace clean up and rodent proofing. I’m very pleased with the overall results.

I highly recommend Rywen Insulation for anyone in need of professional attic and crawl space restoration. They recently completed an extensive project at my home, and the quality of their work was exceptional. The team meticulously removed all old insulation, damaged ducts, and debris, ensuring that every square inch of both the attic and crawl space was thoroughly sanitized and cleaned before proceeding with the new installation.

I was particularly impressed with Anibal, who managed the process with a level of detail that is rare to find. He was consistently thorough, ensuring the rat and mice exclusion was handled effectively and that the new ductwork was installed perfectly. Beyond his technical skills, Anibal was incredibly respectful and maintained clear, proactive communication throughout the entire job.

If you are looking for a company that prioritizes high standards and professional conduct, Rywen Insulation is an excellent choice.

Rywen and their employees are great. The service and quality of work are excellent. They respond quickly and are extremely professional.

We initially had a rodent issue that needed a lot of attention, they have comeback and inspected the affected areas and because of their great initial work, we have not had any further issues.

Thank you specifically to Roni and Axel for their awesome work and service.

Fast job, good work, great guys

5 stars!
