"I will say the gentleman I dealt with from Cronkhite was very personable and professional. We met twice - once for him to look at the deck and take measurements, and again a week or so later so he could give me the price quote - and he was on time, or close to on time, for both appointments. For me this was strictly an issue with pricing. I wanted a cover over my approximately 10x12 deck. He provided me with a quote of $6,224 for an aluminum cover (this included rain gutters, etc. - it would have been a very nice cover judging from the photo examples he showed me). But 4 years ago a metal roof for my entire house installed by Sundown Exteriors was only $8,955. Granted, I don't have a huge house - two bedroom, one bath, one story - but I just couldn't justify spending almost 70% of the cost of my entire roof for a deck cover. But if you have the money to spend, I'm sure they do very nice work."

"Neil did the job fantastically and explained what he was doing throughout, always asked for an inspection to make sure it was done to my satisfaction. Pricing was extremely fair and he was timely and quick. Would highly recommend for any insulation work you need done. Can’t speak on the other work he does, but if it’s on par with what he did for me, then you’d be doing well."

"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 Cornell, 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.
