"We were so happy with our experience with Randy from Paragon Services, we have had him out 2 times in the last month to address both the attic and the crawl space of our new home. After Randy and his team replaced our fiberglass insulation in the crawl space with spray foam, it raised the average air temperature on our first floor by over 15 degrees! I has made a HUGE difference right away and I can’t wait to see the $$ we save on our heating/air conditioning. Paragon Services is fast to respond to messages and phone calls. Randy was able to come out for a quote within a few days we were on the schedule within a week or two. On installation day, the crew was on time and professional. I was blown away by Randy’s knowledge and honesty. I never felt rushed during our conversations or pushed to commit to a purchase. He took his time to investigate the issues, develop an appropriate plan of action, and prepare a thorough quote. He went over everything with me to make sure I understood what he was proposing and why. I learned so much just in our few conversations. I also loved that he not only addressed the issue I called him out for, but made sure any related issues were addressed as well. The prices are very reasonable and their customer service is excellent! I definitely recommend Randy and Paragon Services!"

"Very professional and courteous team. Five team members where here for six hours installing, new fan roof vents, removing old duct work including a bird nest, installed new vents between the beams, discovered builder originally did not properly insulate one area above master bath and corrected that area too. Had insulation blown in very deep to R49 and once done with house attic had garage attic also fixed and insulation installed. We have seen a big improvement, bedrooms are so warm now we keep thermostat on 63 or 65 from midnight to 0800 and 65 to 67 during the day. Garage is not freezing anymore and recently with temperatures at 30 to 10 degrees outside the garage is still between 47 to 43 which keeps any garden, household or automotive products from freezing out there which helps with storage of these products. A professional team from evaluation, quotes, installation, office scheduling, payments and follow-up. Highly Recommended. Thank you, Robert USN Retired"

"Attic Air absolutely lived up to their reputation. They did a GREAT job! I did my research in creating a short list of 3 bidders for the job. I have a bi-level house (4 levels) with 2 attics. We had black mold on the underside of the roof which we had remediated a week before having Attic Air come in to fix our ventilation and insulation issues. Our upstairs floor was cold in the winter and hot in the summer. The attic ventilation and insulation needed to get fixed, and I wanted to make sure I hired a good company to do it the right way so I never had to worry about it again. I made the right choice. The temperature throughout the house is so much more even now. Before Attic Air came out, the basement and sub-basement were freezing and the first and second floors were warm and hot. My over-sized top of the line Trane a/c unit was working overdrive to try to cool the 2nd floor and never could do it. The top floor is so much cooler now than before. It's really going to save my a/c unit in the long run. Attic Air was not the lowest bid of the 3, but you get what you pay for. If you want to get the best quality this is the company you want. I would haven't have changed a thing. Worth every penny!"

"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!"

"We got several quotes for our attic insulation project. We found Jace with Peak Performance to be very knowledgeable, honest and reasonably priced. We scheduled the project, the Peak team showed up on time, finished in the timeframe they promised and did a full clean up. We're really happy with the entire experience and have already recommended them to others."

FAQs for insulation service projects in Mchenry, IL

Local and federal rebates are available for insulation installation, which can significantly reduce your overall costs. Many utility companies offer incentives or rebates to homeowners who improve their home's energy efficiency. Contact your local energy provider or government agencies to learn about available programs in your area, and consult with a professional insulation installer to maximize your savings.

It's not necessary to remove old insulation before adding new insulation, as long as the existing insulation is in good condition—dry, free of mold, and not damaged. Adding new insulation on top of old insulation can improve your home's energy efficiency by increasing the overall R-value. However, if the old insulation is wet, moldy, or damaged, it's best to remove it before installing new insulation to prevent potential health risks and ensure optimal performance.

Insulating a house takes between five and twelve hours for batts or boards, and two to five hours for spray foam or blown-in insulation. The exact time depends on the size of your home, the type of insulation, and the accessibility of the areas being insulated. Keep in mind that projects may take longer if old insulation needs removal, if there's a larger square footage, or if spaces are difficult to reach.
