Insulation Contractors in Corona, CA

"Excellent Service Pride in workmanship Knowledgeable experience Housekeeping at worksite - professional ThankYouâ ¦."

"They came out and cleaned our attic from top to bottom. Took out all the old insulation (which no one will do), vacuumed, sanitized, rodent proofed, new insulated ducting, and came back after our AC was installed to blow in insulation. Crew was very professional. We feel we got our money's worth for sure!"

"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"

"Mike Whiltshire is a professional. His work was excellent."

"Russell was a pleasure to work with, very knowledgeable and helpful with planning and deciding what needed to be done for my home insulation project. His team was prompt and on time every day which really impressed me, especially since they drive from the OC each day! They fully removed my old insulation, cleaned and sanitized my attic, rodent proofed it, and then blew in treated cellulose. They don't do spray foam insulation, but as I learned from this project that's not always the best answer, anyways. Everybody was professional and they cleaned up as they went. I'll hire them back in an instant if I need any more done in the future! Thanks guys!"
