"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 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."

"In 2017, when I was looking to purchase a house in the Rockford area that was needing a full siding install I contacted GF Company in Belvidere. IL, who I found on Angie’s list and at that time GF Co had great reviews. Strangely enough these great reviews are no longer to be found on Angie’s List. It should also be noted there is a GF Siding in Cherry Valley. IL, this is Not the company that I did business with. Ariel Zmijewski (the owner) got me a quote quickly and I decided to purchase the house. A few months later in July 2017, I contacted Ariel again to discuss the finer points of the quote, the price was revised slightly and the Ariel mentioned that once a deposit was paid work could start 6-8 weeks later, but said the install would be finished before the cold weather arrived. I started creating a color layout and Ariel provided some feedback on what would work and not work. To this point I was very happy with progress. In September 2017 I paid a deposit of over $8k (about 44% of final price) and awaited updates for a start date. Nothing happened. In early March 2018 I contacted GF Co by phone stating that I had been very patient and they had had $8k as a deposit for the last 6 months and I had nothing to show for it. After a couple more calls and emails Ariel showed up with his foreman Mark and they said that work would start in the middle of the following week. Much to my surprise the work started on time. Over the course of the next 4 weeks Mark and his crew worked hard, only missing a few days due to bad weather, I even agreed to having some extra work done by the team, some wooden entrance steps that needed replacing for an additional $2.5k. By early May 2018 the job was finished the house looked great and I was very happy with the work and appearance and was getting compliments from neighbors too. The balance of owed of over $10k was paid with 48 hours of the work being finished. Again I was happy with work done, until… A few months after the install a TV cable box started having troubles. Cut a long story short the wall socket died because cable was suddenly defective, also the crew had moved the exterior cable input box and this didn’t help the issue. Comcast fixed it, but I now have an exterior cable showing and they had to drill through the siding. Then around Halloween 2018, less than six months after having the install completed, I noticed that a piece of siding (6ft approx.) had become detached underneath a window, trying to pop it back into place did not resolve the issue. After checking all the other exterior windows I noticed 1 other window was about to do the same thing. I called the GF Company main number and left a message with the receptionist for Ariel to contact me. No response. I called again a couple of times and left more messages still no response. In March 2019 siding problem under windows still Not fixed, I called GF Company again, no answer, and no voice mail. I called a couple more times on different days still no answer or voice mail. I then sent an email to the company and to my surprise I received a response from Ariel stating this was the first that he had heard of it. About a week later (3/26/19) he showed up at my house to view the problem. Ariel stated that he would get someone over to fix the problem, but would not give me a date or time. On 4/2/19 I emailed Ariel again asking for confirmation of a repair date ? Nothing but crickets… On 4/30/19, I sent another email to Ariel requesting that the repairs be completed before the end of May 2019, again no response. Quote / contract says: Customers will receive a Lifetime Warranty on Material and Workmanship Reported GF Company to Illinois BBB on 6/5/19."

FAQs for insulation service projects in South Beloit, 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.
