"I had Tri-Star Insulation come to my house and install blown-in and reflective insulation in the attic. They were professional, arrived on time and did a great job at a very fair price. I would recommend Tri-Star to anyone in need of insulation products. Thank you Tri-Star!"

"Matthew did a thorough quote at my house shortly before Thanksgiving. Matthew was very professional, on-time and friendly. The technology was impressive as you could see the ?cold spots? around my attic space. I plan to execute the job after the holidays. I highly recommend Matthew and Insulation Commandos if you need any insulation related work."

"Since 7/2025 I knew we needed insulation blown into our less than 1300 SF 1973 built home. Got a quote for over $5000, left messages at many more and some didn’t even show up or return my call. On 12/16/2025 I called Angi list and was told someone would be calling me back soon(bet they want!) Well they did and I spoke Nick Martin of Martin Home Solutions and gave me a quote that I was able to pay (We are old!) and he and Jason Farmer came to our home last evening 12/17/2025!!! (Ready To Work!) We were so impressed by Nick’s honesty, open communication and work ethic. We were so very happy to know that we can survive this winter financially with adequate insulation in our attic. Call Angi List today if you are searching for someone for your attic needs, Martins Home Solutions will not disappoint."

"When I had originally contacted Bia Insulation I was pleasantly surprised at how quick and easy the process was to set up my appointment with them. Once everything logistically was taken care of, insulation install process came and went in a swift manner. I was highly impressed with not only how professional but personable Jeremy was. He was my go to guy from start to finish and that meant a lot to me. Having the one point of contact throughout the whole process was breathe of fresh air. As far as savings go, my wallet and my wife are VERY happy. We noticed savings on our bill within the first couple of months."

"He was great. He was able to put insulation into areas that 3 other companies stated they could not do because of the angles of our roof. We started out without insulation in the den area because it is a vaulted ceiling but he was able to work all the way down to the outside wall and put insulation into the difficult areas no one wanted to work on. I would highly recommend him to work on your home if you have difficult areas and need some relief"

Insulation questions, answered by experts

Yes, doggie doors, like all entrances, can let both hot and cold air into your home. However, as with any door in your house, you can take steps to weather-strip your pet's entrance to prevent air leaks.

Expect your home insulation project to take between five and 12 hours to complete on average for batts or boards and two to five hours for spray foam or blown-in insulation. It might take longer if you need to remove your home’s existing insulation, you have a higher-than-average square footage, or accessibility is limited.

Bathroom wall insulation not only keeps the area temperate, but it also reduces instances of mold, mildew, and rot. Bathrooms, after all, are havens for moisture. With this in mind, it’s absolutely worth it to insulate bathroom walls since it saves money in the long run. You won’t have to hire a pricey mold remediation service down the line. Also, insulation decreases outdoor noise and lowers energy costs.

As long as a licensed professional installs your gas lines, you don’t have to do anything extra to prepare for cold weather. If there are pipes that require a wrap, your installer should have done it for you already. If you want to be absolutely sure your gas system is good to go for winter, the best option is to schedule a gas line inspection.

The cost to install a radiant barrier ranges from $700 to $2,800, depending on the size of your roof and the type you choose. Most people pay an average of $1,700 to install a radiant barrier. Foil options, both single- and double-sided, cost between $0.10 and $0.90 per square foot, while spray-on options start at $0.60 and go all the way up to $1 per square foot—which can add up quickly.
