"We badly needed insulation in our attic. We got three quotes. Weather Shield was not only the most reasonable, but the only company in which the owner both gave us the quote and installed the insulation with colleague. We could not have asked for more professionalism or better service. Would highly recommend Gus."

"Arc was great from the start. We were given a complimentary consultation by Steve Garrett, who gave us a detailed explanation on the issues we may have with our attic insulation and why our energy bills may be so high. We chose to have our attic insulated and our ducts sealed. Our ducts saw a 93.5% improvement, and we immediately noticed the difference in the temperature of our second floor. Even during this prolonged heat wave, we have been able to keep our temperatures much lower than before. The attic insulation has also decreased the temperatures of the upstairs. It has been a remarkable difference. We are fully expecting our house to be more comfortable in the winter as well. Steve is honest and reliable and we would not hesitate to recommend Arc to anyone who needs insulation and duct work."

"I met Robert for an estimate. Robert is a straight shooter, gave a competitive estimate, and no pressure at all. I decided to go with him after another estimate I got was borderline gouging. I was impressed with how efficiently and quickly his crew worked. These guys know what they are doing. Many companies can insulate an attic but Attic Air can also replace attic and bathroom fans. Make sure your soffit though has holes in it to let air into the attic. This was an optional piece for me but the crew chief explained to me the new attic fan that was being installed would burn out if there was not enough air coming in from the soffit for the fans to circulate. I also took advantage to replace two other very old bathroom fans with more powerful Panasonic 100 cfm LED fans to take advantage of the crew being in the attic. My second floor used to be 3 degrees cooler than what the thermostat showed on the first floor, but is now 1 degree or no difference. I am hoping I won't need a separate cooler fan in the summer on the second floor. Didn't need a separate heater for winter at least or shiver unless I brought up the temperature on first floor."

"Efficient and professional. The inspector on this new construction had one issue with insulation and Ryne came out that day and his guys corrected it that day. Smooth and on top of it. I wish all my subs were that good."

"I am very happy with the work done by Green Attic Insulation. David and Charlie were very friendly, professional, responsive, and flexible in working with my changing needs. I originally was looking into insulation but then discovered there was mold in my attic. As the job grew, David, Charlie, and their team worked with me to address the additional parts of the job. I really appreciate their knowledge and the thorough job they did. They took many pictures of their progress and kept me informed each step of the way. Thank you very much!"

"ADL blew in some insulation into my attic and reinsulated a skylight. They were thorough and professional. ADL was mindful of my property and cleaned up the work area upon completion. I would definitely recommend them."

"We reached out to Dan with the issue of freezing pipes and cold rooms in our old house. Dan inspected the house and proposed a plan to remedy these issues. Aside from the more traditional air sealing and insulation solutions, Dan also recommended insulating the area of our house above our soffit, which was difficult to access but that appeared to be a major insulation issue. I should add the other firms we requested quotes for did not identify this area in their proposal. I firmly believe the proposals from the other firms would not have fixed our issues. Dan worked for ~2 weeks on air sealing our attic and house, adding insulation to our attic, removing our soffit and adding insulation and reinstalling soffit. Work was done well and within budget and at a fair price. Dan is very easy to work with and takes pride in his work. We are very happy to report our pipes have not frozen and the cold rooms are no longer cold - would highly recommend Dan to others - he went above and beyond."

"George came out promptly and did a thorough inspection of the crawlspace and provided options on what can be done. The insulation work was performed by Jesus who also found and fixed two foundation cracks. Encapsulation was done by Juan's team and they all did a great job. They were able to perform all the work with a very narrow opening into the crawlspace and were also able to fit in the dehumidifier. After installation there was a minor issue with the dehumidifier and Craig came right away to fix it. Great experience and I'd definitely use their services in the future if need be."

Insulation questions, answered by experts

Completing an attic insulation service in Glenview takes one to two days for a standard single-family home. Crawl space and basement rim joist projects take one day, while whole-home upgrades require three to five days. You must also account for the permit review process, which adds three to ten business days. Seasonal demand peaks in late fall and early spring add one to three weeks of lead time before local contractors begin work.

Helpful?

Proper insulation service directly eliminates drafts and cold floors during harsh Glenview winters. In the summer, updated attic insulation blocks radiant heat, keeping your upper floors cool and comfortable. Upgraded materials also act as a sound barrier against noise from nearby expressways and flight paths. Furthermore, adding proper vapor barriers manages the elevated humidity from Lake Michigan, preventing moisture buildup and keeping temperatures consistent across all levels of your home.

Helpful?

Your top priority for insulation service in IL is an attic assessment and upgrade to reach R-49 to R-60 levels. Next, add rim joist insulation in your basement to stop heat loss during cold winters. Combine these upgrades with thorough air sealing to close gaps around plumbing and electrical penetrations. Always hire a professional to check for hazardous vermiculite or older fiberglass materials in your attic before starting any removal or installation work.

Helpful?

Glenview falls within Climate Zone 5, which dictates strict minimum R-value requirements for any insulation service. The extreme temperature swings and frequent winter freeze-thaw cycles place heavy thermal stress on your home. Additionally, the lake effect increases local humidity, making vapor barriers essential for moisture management. Because harsh winters limit unheated space work, schedule your comprehensive insulation upgrades during the spring or fall for the best application conditions.

Helpful?

Watch for ice dams on your roofline during winter freeze-thaw cycles, as this directly indicates failing attic insulation. High utility bills compared to your neighbors also point to inadequate coverage. Inspect your attic for frost on the roof sheathing or flattened, compressed materials. In your basement or crawl space, musty odors and visible mold signal that your previous insulation service in IL absorbed moisture and requires immediate professional replacement.
