"I had three different people groups in who came in and gave me an estimate and what might be needed and what they discovered is that for some reason when the house was built 16 years ago, they did not really do adequate insulation.  I did feel very comfortable with Precise & Snug.  They were good about being able to show me pictures.  They showed how it looks up on the attic.  When you are in the process, the told us that they can do this and that and it would cost so much and the final bill was $20,000.  I would not use their service in the future."

"After contacting Jace, he came and did an assessment. He sat down and gave us a very fair bid on adding blown in insulation to our attic. We accepted the bid and he and his partner were back in a week’s time. They were very timely on arriving and were finished in their estimated time. They cleaned up the area very good. I highly recommend this company for any insulation needs."

"I would like to say that we would use GF Company in the future.
The Positive:
 The sales representative, Ken Jr., was astounding.  His knowledge of his field was excellent and I enjoyed talking with him.  He was also very thorough with his estimate and writing down in great detail what we wanted to have done.  I hope we get him as our sales representative when it is time to do our roof or our windows.
The work was done exactly as Ken Jr. had written on the estimate.  For the most part the work matches the current look of the shed and it has already filled the water barrel.  
The Negatives:
It was difficult to communicate with GF Company.  We had originally received a quote from Rick a year before the work was done and we contacted GF Company many times to speak with him about getting the work done, but none of our phone calls were returned.  Finally we asked for someone new and we got Ken Jr. sent to us.
After we paid our half-down deposit, we were told that we would get a call in about three weeks to find a date for the work to be done.  After about 5 weeks we tried contacting GF Company.  One phone call had us speaking with a lady on the phone who said that someone would call us back soon, but that never happened.
We never received a call to tell us when the work would be done as we wanted to have someone home to make sure things were done to our specifications.  Several days after our phone call was not returned, we received a text message from our neighbor telling us that someone was doing work on our property, but my wife and I were both at work and by time we got home the work was done.  Since Ken Jr. did such a great job with writing down what we wanted, we did not have any issues with what was done.
It appears that one of the items created on site for our downspout on the shed was likely spray painted on site.  The paint job has already faded, but we can find some paint to paint it again.
Overall, it sounds like we had a bad experience, but we did not.  The work that was done was done well and the sales representative we worked with was very knowledgeable.  We would use GF Company again and recommend them, but encourage folks to have patience with communication.

FAQs for spray foam insulation projects in Stillman Valley, 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.
