"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"

"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."

"Geovany and his team did an amazing job at my house cleaning attic removing all debris lid insulation, sanitizing and air sealing attic, installing new insulation and radiant barrier. Job was done in a clean and professional manner. Team was polite and professional. I would recommend Fibers Insulation to anyone looking to upgrade or replace their insulation or just looking to add radiant barrier to their attic for a cooler more energy efficient home."

FAQs for spray foam insulation projects in Fontana, 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.
