    I'm the type of person who has a spreadsheet for everything. My spreadsheet for insulation and sealing for my 1890s Victorian was comprehensive, looking at review counts, ratings, years in business, licenses, BBB, Google, Yelp - you name it. In the end, I shortlisted the top five companies, Insulation Alliance being one of them. After capturing all the quotes Insulation Alliance was right in the middle of the pack in terms of pricing, but it was clear they were ahead of the others: -Clear communication both via email and phone calls -Responsive to inquiries and changes, even allowing me to select which specific model fan I wanted in my attic -Spent the time to explain the tradeoffs of different approaches On the day of, the crew showed up on time and made short order of our two attic spaces, sealing both, putting blown in cellulose in one and fiberclass in the roof of another, and installing a temperature controlled Smart attic fan. The crew put down protective floor covering, plastic sheeting and cleaned up after themselves. They were incredibly responsive to feedback and made the process a breeze. I'd consider them for any future insulation needs.

    Hired Umar to do a vaulted ceiling insulation. Very knowledgeble, the ceiling job came out so well and room stays cool. minor concern while drywall finishing but Umar worked to close this problem and understood our concerns, Will hire them back for the xterior wall projects at a later date. Highly recommend Umar!

    Axel is seriously one of the greatest service professionals I've ever worked with so far. He…read moreconducted a thorough investigation and by the end of it, not only had I learned a bunch of things I had previously misunderstood but he laid out what work I should actually consider and in what order. No hard sell. No BS. He literally said the words "here's what I would do if it were my home" before laying things out in priority order and detailing what he deemed necessary and why. That's exactly the type of professional I want because you can tell they truly have your best interests in mind. His team was also great when it came time to do the work. They went extra distances left and right to fix things along the way and point out new issues. Their dust encapsulation and safety gear were very great to see as well because it shows attention to detail along with care for the customers as well as their own employees' health. We ended up with quite a large job with them but I would hire them again for anything I can. Simply exceptional.

    We live out in the country on a big property, and rodents in our walls and the crawlspace under our…read morehouse 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.

    Beyond easy experience with Chris. My dryer suddenly started giving off a burning smell, which I…read moremistakenly attributed to the lint catch being overloaded. But even after cleaning it out, the smell wasn't going away. Then the vent started giving off either smoke or steam, and in a panic I immediately turned off the dryer. Thank God I didn't start a dryer fire. The second I shut it off and made sure everything was ok, I opened Yelp and searched for a dryer vent cleaner. Chris's Insulation came up, he had great ratings, he was super close by, so after calling a different service and going to voicemail, I called Chris. Chris picked up after the second ring. When I told him that I needed someone to clean our dryer vent and what had happened, he said he could come out either between 5:00 and 6:00 pm that evening or the next day. It was already mid-afternoon when I called, so I was surprised to hear him say he could still come out same-day, but I decided to have him do that since I was free and also still a little shaky following what happened with the vent either smoking or steaming. Chris showed up during the window he quoted and wasted no time getting to work. He started the second he arrived and was done within the hour. His pricing was incredibly reasonable and fair and so far, in the couple of weeks since he was here, we've had no issues with the dryer. Before he left, he also sent us a ton of pictures of what the vent looked like post-cleaning. Super happy and relieved.

    Professional service and they were able to come same day, which was the most helpful for me.read more

    I started to hear little pitter patter footsteps and gnawing sounds at 5 am, and on day 2 of this,…read moreI messaged Attic Crew. They sent someone the next morning for an assessment and got us scheduled right away! In the interim, they gave us recommendations to deter the rats, which worked. Carlos and his crew arrived on time and finished quickly. The price was reasonable (honestly, on the cheaper side yet the quality and professionalism was great!). There was an issue with a short circuit because a rat chewed through the insulation that we didn't notice until the weekend, but Carlos responded immediately and came over to fix the issue. We are so grateful to Carlos and the Attic Crew for helping us with rats in the home, helping us feel more confident about keeping them out for the foreseeable years, and for all of their professionalism, knowledge, and expertise! Would definitely recommend!

    We worked with Jay, Andres(?), and Angelica. They really went above and beyond to help educate us…read moreabout the process of installing a moisture barrier and all the factors that go into successful rodent abatement. The communication was excellent, even on a holiday weekend I got called back within an hour of reaching out with questions, which I certainly did not expect! They arrived promptly for appointments and were thoughtful about avoiding tracking dirt into our home. They worked with us to customize their work to our coastal climate and were very transparent about exactly what materials they would be using (all top of the line, industral-grade!). I have pets and toddlers and they took my concerns about chemical disinfects seriously and offered several options to make sure I was comfortable with what was used in our home. They really seem to take pride in their work and enjoyed sharing before and after pictures to demonstrate all the improvements they made to our crawl space. I could not be happier with my choice to hire them, and plan to work with them again when I'm ready to replace my attic insulation.
