"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."

"Everything was fine until I got the final bill. The estimate they gave was different and the final bill was different. They had put extra charges. When I called them about it, they didn't back down. They also said that because of the extra insulation they used they did they couldn't reduce the cost. Other than that, the job was done fine. At one point, the insulation had blown in, they had a little problem, but that was worked out."

"The technician was professional and did a very good job.  All the old insulation was removed, bagged and cleaned up.  In addition, they helped us out by removing some old items remaining in the crawlspace.  The space has a very low ceiling and they did a great job spraying the foam on the walls."

"Dillon was a great guy and worked fast and efficient. My house is 50 plus years old and the duct work had never been cleaned. Post the work, the house even smelled better. I am in the middle of a complete remodel and living in the house. I had all 11 vent grilles removed -(saved Dillon a pile of time not having to remove and re-install) and I would have thought a discount would have been in order."

FAQs for spray foam insulation projects in Princeton, 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.
