"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."

"My attic was poorly ventilated — damp, musty, and overdue for attention. After deciding to bring in a professional, Randy came out to my home, thoroughly assessed the problem areas, and put together a detailed quote on the spot. The scope of work included removal of the existing insulation, air sealing around all attic entry points, sanitizing, air baffle installation, and installation of new Weather Blanket cellulose insulation. The new cellulose achieves an R-value that meets or exceeds Illinois code requirements. I couldn't be happier with the results. I've already noticed a meaningful improvement in temperature consistency and overall comfort throughout my home. If you're looking for a trustworthy, professional insulation contractor, I wouldn't hesitate to recommend Paragon Insulation & Services."

"Daniel and his brother are very professional, know what they are doing and are great problem solvers and equally as important, really care about the work they are doing. They found that a bathroom vent was not installed properly and ended up going to Home Depot twice to hookup the vent properly. They did the right thing and got it done right. I will be working with Daniel and Mendieta Insulation again and I will refer them to family and friends."

"Our 1926 home had an uninsulated crawl space that made our hardwood floors freezing and overworked our furnace. We got five estimates, and David with Arc Insulation stood out?he arrived on time, used a temperature gun to show where we were losing heat, and brought insulation samples to show what they would use for our job. Their estimate was very detailed and reasonable. Luis and Juan came out and completed the job in just a few hours and were professional throughout. We?re happy with the results and would highly recommend Arc Insulation!"

"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."

"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!"

Insulation FAQs, answered by experts

The lifespan of cellulose insulation is 20 to 30 years, on average. That said, it’s important to start checking your insulation after year 10 to check for degradation, mold, mildew, and other potential problems. Every 10 years, you should also confirm your home’s insulation is in line with updated local building codes.

No, 55 degrees Fahrenheit is not too cold for a house, as it’s a temperature that will keep your pipes and appliances from freezing. Well-insulated homes can even go to 50 degrees, but check with an HVAC pro before opting for such a low temperature. Stick to 55 degrees to be on the safe side.

You should not use spray foam insulation in several specific areas. Avoid applying it in spaces exposed to high temperatures, such as near electrical boxes or recessed lighting, unless the foam is specifically rated for such use. Applying foam near electrical boxes can damage the wiring, and using it too close to lightboxes or recessed lights creates a potential fire hazard. Additionally, do not use spray foam in areas prone to shifting or movement, as this can lead to cracks and gaps in the insulation. Finally, open-cell foam is unsuitable for use below ground or in areas exposed to moisture because it can absorb water, which compromises its insulating effectiveness.

A-frame houses pose specific challenges that can make heating difficult. Their open concept design with high ceilings can lead to a colder lower floor and a warmer upper floor. A ceiling fan that pushes warm air down or pulls cold air up, depending on the season, can easily counteract temperature issues. Additionally, certain types of heating do better in these homes than others. For example, heated floors tend to be more practical and energy efficient than baseboard heating.

Because of the moisture concern, open-cell foam requires a vapor barrier. The barrier protects against high humidity and moisture exposure in rooms such as basements, bathrooms, or exterior walls. It wouldn't be necessary in dry interior spaces.
