Uneven attic insulation can leave some rooms hotter or colder even when the HVAC is working fine. A professional may spot air leaks and thin coverage that attic insulators often miss, which can help reduce energy loss and comfort problems.

Morgan Watson says, "We just had a fantastic experience with Avi and his team on a refresh of our small upstairs bathroom. From the start, Avi was committed to making us happy and delivering high-quality work.It was our first experience with a renovation or remodel of any kind, so Avi's patience and help in walking us through everything was appreciated. Aside from our home purchase, it was our biggest investment to date, so we also appreciated his transparency in pricing and scope expectations.His crew was equally helpful, respectful of our home, and detail-oriented. I especially loved working with the plumbing team couple, but absolutely everyone was kind, doing their best, and happy to complete fixes and answer our questions.Ultimately, the project was completed on schedule and stayed within budget. The final result looks great, I finally trust the plumbing and electrical lurking within the walls, and I would absolutely recommend AE Construction and Remodeling to anyone looking for a refreshed space."See more

Nicole A. says, "Ok, so I am a seriously anal human being when it comes to finding the right service provider at the right price. I interviewed — and I kid you not — eight different Bay Area contractors just to get a feel for pricing, transparency, and overall vibe. OT Bay stood out immediately. Ron, our project manager, has been consistently honest, kind, and communicative from day one. There was no pressure or vague answers — just clear explanations and realistic expectations. That alone made a big difference for me. We hired OT Bay to demolish and remodel our kitchen countertops, fireplace, and shower. The process was organized, the crew was professional and respectful of our home, and the work turned out beautifully. They showed up when they said they would and followed through on what was discussed. We did run into a few design issues along the way — completely on us — and OT Bay was incredibly accommodating. Instead of making it stressful or transactional, they were understanding and proactive in helping us adjust the plan. Ron would often say that he wanted us to walk away loving the finished work, and I genuinely feel like he meant that. He worked with us to make sure we were happy with the outcome. I’m always cautious about getting taken advantage of with service providers, especially when pricing isn’t rigidly set. From day one, OT Bay was transparent and straightforward, and over time that built a level of trust I honestly didn’t expect to have with a contractor. If you’re looking for a team that communicates clearly, handles challenges professionally, and stands behind their work, OT Bay Builders is worth considering. Ron and his team were a solid choice for us."See more

Great experience working with Symonds and Allison. Our house had old insulation and Attic Renew 360 came and gave us a quick estimate. Got an appointment the next day to do clean, sanitize, air seal attic with r-38 insulation. Also cleaned up the crawl space and air sealed it as well. Very competitive price and professional job. Definitely recommended.

We worked with Mike to get our attic insulation and HVAC duct replacement done. He was very informative when he came the first time to provide us the estimate. Pacific Air provided us with the best quote for the service. Mike arrived with his team on time as decided. They were very efficient at their job, and professional. They provided before and after pictures of the attic insulation too. After the job was done they cleaned the working area, our garage and even the street in front of the driveway. We are really happy with their work and would definitely recommend them.

From Lucia F.

Johnson’s Insulation
Johnson’s Insulation
I asked three different insulation companies for an estimate. After speaking with Miquan from Johnson's Insulation, I felt very comfortable with him because he provided reasonable answers to my questions. He did not try to oversell anything and he was very polite. I was provided with a quick response when I asked for the quote, and I was able to schedule very soon afterwards. His crew came out and they did exactly what they said they would do. They removed the old blown in insulation, cleaned the attic and sealed it, installed new insulation and a radiant barrier. The radiant barrier really did the job. My house is much cooler now. The quality of the work they do is outstanding. They even showed me pictures of my attic after the installation, and I am very satisfied. Thanks Miquan, I am a very happy customer.
