Mark F.

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!

Attic Pros

East Oakland

We had rodents dancing above our heads at night in our low head-room attic. We called Attic Pros…read morewho did a cursory "inspection" and recommended complete replacement of attic insulation, replacement of most A/C duct work in the crawl space below the house, sanitizing, and sealing up "all" entry points for critters. It was very expensive but we went with them mainly because the "inspector" (a salesman through and through) had excellent English and promised to personally manage the project. He answered one subsequent question and then disappeared, never to be heard from again. The estimated 3-day job took 3 weeks, with schedules shifting daily, different crews, minimal work days, redundant and often incorrect communication via text and email, and no explanations of what was going on. The crews were friendly but spoke minimal English. It was difficult to understand what was done, not yet done, or not intended to be done. Once they left, the critters remained. Staff came back 3 or 4 times to seal additional openings ... to the wrong area (crawl space rather than attic). The most recent visit by Jorge was very good. He had good English so his explanations were understandable and helpful. He found and fixed two more openings - these at roof level - and recommended a spray that can repel rodents from returning. I bought and used that (why don't they do that themselves?) and the first night at least was the first "quiet" night in months.

Tom is very professional. He explained the details of attic cleaning they do, showed the photos and…read morewhat all cleaning service needed, and followed up with itemised quote. Very quick in responding to queries over the phone and text.

St. Elizabeth, Fruitvale, East Oakland

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.

Great work and very thorough. They spent more than two hours performing the work. The price was…read morevery fair as well! Thank you!

Caleb picked up every time I called or texted and walked me through what that work actually involves, which I knew nothing about going in. He set the free inspection up directly with our agent so we didn't have to be there, and the report he sent back was more detailed than we expected. He never rushed me, and never made me feel dumb for asking the same thing twice. He got that we were first-timers and in over our heads, and he was kind about it in a way that isn't all that common. Booking the work with them as soon as we move in.

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!
