"We recently had blown in insulation installed in our home and couldn’t be happier with the experience from start to finish. The team was kind, professional and incredibly prompt. They showed up on time explained the process clearly and treated our home with respect. What really stood out was the pricing after receiving a much higher quote from another company their estimate was very fair and transparent with no pressure or upselling. It was clear they care about doing honest work at a reasonable price. The installation was completed efficiently, and the whole process was smooth and stress-free. I would definitely recommend them to anyone looking for insulation work great service, great value and great people."

"These guys were meticulous! The March hail storm did serious damage. Nate and his crew completely re-sided our home, and replaced all soffits, fascia, gutters, and trim. Everything is perfect. The attention to detail, outstanding. We have nothing but positive feedback for the job that Williams Home Exteriors has done. Will definitely use them when needed for future work."

"This company cares. They put people above profit. I was in a bad situation, after a nasty winter my roof seemed to be disintegrating before my eyes. It went really fast. Then Daryl stepped up to help me out of a difficult situation. Within hours they expedited the crew, and Walter and Lauren ordered materials and made my roof a priority. Now with three days of rain coming I know my house is protected and it looks gorgeous."

"Contacted a few different companies and had two come out to inspect a large crack in the foundation. First company came out and indicated that the foundation had failed and needed piers put in to stablize the foundation. Crawlspace Solutions came in and indicated that they felt there was nothing failing with the foundation and that they could inject the cracks and warranty the work regardless of if there was a larger issue that required piers. Scott was the person that estimated and completed the work. He was extremely responsive and did a very good job of injecting the cracks. When Scott came to quote the work he also offered a price to apply spray foam to the walls and the sill to replace the fiberglass insulation that the previous owner of the house had on the crawlspace walls. Price included in review was to inject 2 cracks and apply the spray foam. Really glad we had the foam insulation put in. Way cleaner, durable and sealed up some areas that the other insulation could not take care of. Scott also spent extra time explaining some other areas to keep an eye out on to help ensure the foundation area is well managed from any further potential issues like down spout discharge locations, hose connections and just general drainage of the property. One of the concerns we had was if we spend all this money on the injection and the foundation ends up needing to have piers put in, how would that impact the warranty. Scott assured us that if any additional settling occurs and the repair fails, they would come back and repair the injected cracks after the foundation was stable."

FAQs for spray foam insulation projects in Grant Park, 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.
