    Radiant & Vapor Barrier, Solar Energy Installation, Attic & Crawl Space Cleaning , and 2 more

    "They cleaned attic, installed new pink insulation in attic floor, laid in new plywood flooring where specified, and installed radiant barrier on rafters. The new insulation reduced temperature in attic and also to the 2nd story, which helps to cool the house better. The technician and workers were hard working, pleasant and polite, and left everything clean afterwards."

    "The team was excellent. Professional, timely, and courteous. Jessie the sales rep was very reliable and straight forward. He answers calls texts promptly. Did not push for extra sale, as a matter of fact they fixed things for me in the attic (switch box and AC ducts) without any extra charge. Mark the installer was very knowledgeable and did a thoroughly job. I would definitely recommend this company and team. I have dealt with many many contractors in California and these two were the best."

    "They were very professional & very knowledgeable. Straight forward about the service needed and provided. After they serviced our furnace we took them up on their recommendation to properly insulate the attic, sanitize and seal. Happy with service and they really tried to work with us and our budget as much as possible. Will def hire them back and would def recommend."

    "We hired Pro Insulation about 1 week prior & job completed in 1 day, Jan. 31, 2020. Estimate/inspection performed by co-owner, Michael, who is extremely knowledgeable and offered advice & service that I did not know the attic needed ( we live in an area of high outside summer temperatures [ 110 degrees on a bad day ], but 35 degree and above winter temperatures ). 3 workers arrived on-time with all supplies needed. They prepared the house for repeated entry of workers & bringing-in/taking-out materials. They removed all 1986 old insulation when the home was originally built, vacuumed the attic floor as well as the beam surfaces for old rodent pellets & dust, sprayed entire attic with disinfecting spray, checked the A/C / heater ducting systems for air leaks & taped sealed if needed, they checked for any rodent entry access points and secured them ( I think any access points were found, but two little beasties got in from somewhere? ), installed solid insulation rolls on vertical surfaces, installed thermal barriers on the attic ceiling and then blew-in R-38 cellulose with impregnated boric acid insulation into the attic. The thickness of the blow-in was monitored by placing a tape measure like stick to make sure the insulation was at R-38 thickness. They checked for thoroughness of job quality. They also sealed the exterior chimney-to-attic for cracks and squirted in that foam barrier. They cleaned up the attic, the interior house; the exterior house. Finally, as promised, the other co-owner, Evelyn, mailed us the paperwork to apply for local city rebate as well as the gas utility rebate as well as informing us to check our future 2020 tax preparation for any Federal and/or State energy rebates. Bottom line: I would recommend Pro Insulation highly. The owners are directly involved with the project, completed on-time as promised, workmanship was perfect, and estimate = actual price paid. Full disclosure: I am a repeat Home Advisor customer ( partial re-roof job + repair two exterior iron gates ), but I repeat business with Home Advisor because I trust their vetting system to recommend highly qualified / trustworthy / fair-priced contractors. Would I use: Pro Insulation again - YES / Will I use Home Advisor for some future major project around the house - YES. signed: Scott G., MD in Riverside, CA"

    "Everguard is the only company to use - period. They provided on the phone estimate while other companies come out and give a 2 hour presentation and ask if "your wife will be home" because they want everyone to be involved in the decision - this is not a decorator item - its insulation! I had my attic and walls blown in and it took 3 guys a complete day to do, and they were all very helpful and pleasant to work with. I also added a ceiling with sound proofing which took a few hours the next day. Everyone was accommodating with my needs. Do not bother with any other company!"
