"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."

"The team were very professional, owner came at end of day to check up on quality of job (I asked him to look at my attic insulation, he could have easily conned me into paying for more - he didnt, and told me I didnt really need it... he found another insulation issue but recommended I solve it DIY style!)... so he wasnt interested in the $$$$.... Once he found I was happy with work he left me an invoice, no pressure to pay on the spot. The work has done exactly what he promised and I can recommend using them."

"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 insulation service projects in Peru, 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.
