"These guys came out right away, gave me a fair price and did the job great ! The toughest part was removing old insulation, getting it out of my house and cleaning it all up. They did all that and sealed up my basement tight ! Using their foam insulation they filled in all gaps. And they did it in one day ! We now notice our house stays a little warmer and no more mice ! Kyle and his crew were fantastic and I recommend them highly. -- Alan B - Sun Prairie"

"The handyman, Paul, was punctual, professional and did quality work. He replaced the small section of my wood soffit that had water damage with new wood, painted it and caulked. He cleaned up the area when he was done. Paul also re-secured several of my window shutters that had loose screws. He spray painted the screw caps to match the color of my shutters."

"USA Insulation came out and blew in the pink stuff up to R49. The crew arrived on time, was professional and very thorough with what they were going to do before starting, communicating during of their progress and then a 'show and tell' after the work was completed. Cleanup afterwards let my house cleaner than before they showed up and only took them around 1 1/2 - 2hrs from start to finish (for a 1425 sq ft attic). The entire process, from start to finish, exceeded my satisfaction and we will most certainly be recommending USA Insulation to our friends and family."

"This company did very careful and professional work.  As I said, it's a huge job.  They draped the rooms with plastic sheeting so that we wouldn't have too much plaster dust everywhere (some always escapes, but it was minor).  They patched all the holes that they made. My recollection is that they did the job in 2 - 3 days.  (I'm writing this review several years later).
One issue we ran into, which was not their problem, but you should consider it, is that when they started spraying in the foam, we discovered that we needed tuckpointing done, as the foam started oozing out like toothpaste in a few spots on the outside.

"After contacting Jace, he came and did an assessment. He sat down and gave us a very fair bid on adding blown in insulation to our attic. We accepted the bid and he and his partner were back in a week’s time. They were very timely on arriving and were finished in their estimated time. They cleaned up the area very good. I highly recommend this company for any insulation needs."

FAQs for spray foam insulation projects in Rockford, IL

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.
