"It is rare these days to find a great company with good values. This is one of those instances; I cannot say enough, good things about the professionalism of the employees at the office and those that showed up on site to install wall insulation. They showed up at the beginning of the two hour window, which was fantastic and explained everything with upfront pricing. We even asked for additional insulation and they were able to accommodate. Our home walls are now insulated and we even noticed a difference right away. From the time of arrival to completion they were nothing but exemplary. Thanks again for running an honest and professional team! Highly recommend to anyone out there looking to insulate your home!!! Notability, they were well below other companies on pricing too!!!"

"I converted my garage into an ADU and the building plans required a certain R-value we could not achieve with fiberglass insulation alone, the other option was to use spray foam or foam boards which were significantly more expensive. Ethan from Insulation Labs spoke to my Title 24 company and got them to re-calculate the energy title, make some adjustments and covert it to fiberglass. He saved me A LOT of money and, got the job done in a day and easily passed the inspection the day after. Great insulation contractor, very good customer service."

"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"

"After talking with several attic clean out and insulation, wall insulation companies, I decided to go with Marathon Insulation. Johnathan was very helpful and professional, gave the best choices for my issues, without trying to upsell like some of the others. After getting the attic and walls insulated (with attic clean out) I can already feel the heat stay in the rooms much longer and the walls much less cold to the touch before. I highly recommend Marathon Insulation! They were always on time, delivered as promised, and cleaned up after."

"After having a new air conditioning system installed, to replace an old inefficient one, we decided to make sure our attic had the correct insulation as well as the appropriate R-value. Since our home was built in the 1950's, the insulation throughout the attic was minimal. We hired Insulation Commandos to survey and provide us with the appropriate solution. The solution involved removal of the old insulation, cleaning the area, and installing the correct insulation based on our homes location. We now believe we can keep our energy costs down and provide less strain on our AC system. Great job team!"

"Alpha insulation is a good choice. Their installation was great. The guys cleaned up all their mess. Which is a plus for me. Miguel was easy to talk to. I told him what I wanted done to my house and he gave me a great price for what I asked for. So I hired him. I would recommend alpha insulation to friends and family."

"This business is great to work with! They showed up early and got right to work. They laid down protective plastic as we have blown insulation that gets everywhere. They installed attic and subfloor. I thought they would be here all day. They were down in about 3 hours. Quality work, professional and very informative and clean!"

FAQs for spray foam insulation projects in San Dimas, CA

Old insulation should be removed when it shows damage, contamination, or heavy deterioration. If you notice water stains, rodent droppings, mold, or large gaps, plan on taking it out to protect your home’s energy performance and indoor air quality. Removing compromised material eliminates health hazards, cuts energy loss, and sets the stage for a safer, more efficient attic—all while keeping utility bills in check.

R-value measures how well insulation resists heat flow—the higher the number, the better it slows heat transfer. The right R-value keeps your home warmer in winter and cooler in summer, saving energy year-round. Match the rating to your climate zone and have a pro verify performance over time, because moisture or settling can lower R-value and cut efficiency.

Attic insulation can stay in place for 80 to 100 years, but its performance often drops after the first 15. As dust, moisture, or mold build up, the material loses R-value and allows heat to escape. Schedule periodic inspections so a pro can tell you when replacement makes sense—helping you keep energy bills down and indoor comfort up.

You can over-insulate an attic. Beyond the recommended R-value, extra layers don’t add efficiency and can trap moisture, leading to mold or reduced performance. A local insulation pro can measure current levels, confirm the right target for your climate, and advise on any adjustments so you avoid future energy or maintenance headaches.

Insulation can be damaged by mold, pests, water leaks, or accidental electrical contact. When the material is compromised, it loses R-value and can introduce health hazards. Removing and replacing affected sections restores efficiency, while routine inspections from a qualified pro help you catch problems early and keep your attic safe and energy-smart.
