"Tom was excellent! The only reason, not a 5 start, is because we ended having to supply the plywood for them to use in the attic to do the spray foam insulation, and they were supposed to have brought that. Tom always got back to me. Looking to add some blown in insulation soon, and planning on using this company."

"All of the people (salesman and workers) were very nice and easy to work with but there was a disconnect between them. The salesman obviously had never done this kind of work so some things he thought could be done actually wouldn't work. For example, in the kitchen wall, one of the biggest problems with cold intrusion comes from a covered over glass brick window. The workers were unable to fill behind the cabinet there because the drill would have broken the glass, so that will still be a spot of cold intrusion.
The other major problem of disconnect was a crawl space in a room addition. Apparently it is so shallow that no one can fit into half of it to spray. I can't believe the company doesn't have a remote camera they could have used to determine that. The end result is that only half of my crawlspace got the spray foam. They offered to cut a hole in the floor and try to do it that way or to dig around two sides of this room and spray the outside. I passed on those two solutions.
I waited more than three weeks for the salesman to get back to me with those possible solutions. I feel that was poor responsiveness and a lack of professionalism.

"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."

"We had a different person who came out before them who was horrible and then I tried Crawlspace/Basement Waterproofing Solution because they were reasonably priced and they worked with me on scheduling their time so that they would be there when the electrician are there. They worked together with the electricians and were all done. They were wonderful. It was an all-day project but everybody worked together. Everybody showed up, everybody cooperated, and it was all done in one day with a big job. They were very good with the whole thing. The price was really good deal and all they have to do is seal from the outside to the inside. The biggest thing for us is that, they were here when everybody is here to do one thing. They are really good and we only had one problem but it was all filled up. This company gave exactly what we needed, showed up when they are supposed to, and did a great job. It was perfect. I would recommend right away to anybody before anybody else.  We were very impressed with them."

FAQs for spray foam insulation projects in La Salle, 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.
