"I wanted reflective foil installed under the joist in my attic to help cut attic Heat. The Cronkhite sales rep suggested their own insulated foil product, which I deemed Superior to what I had planned. They installed their material, we're careful about the blown in attic insulation and stepping on the existing ceiling joists. they did a good job, in a timely manner, for a job that was difficult, hot and not very pleasant."

"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.

FAQs for spray foam insulation projects in Waynesville, 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.
