"Insulation Commandos is an outstanding company! Excellent communication with Matthew (phone, text and emails), detailed quotes with line item breakdown, photos throughout the process and video, fast service and completion of work. Insulation Commando's went beyond my expectations in my home repairs, I highly recommend them. From the first inspection, material removal, installation of new insulation, air sealing of crawl space, to the attachment of the floor joists.. I knew I made the right decision. They made my house, my home again! I look forward to hiring them to complete additional projects."

"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."

"We met with 3 different companies to advise on getting solar panels. The first 2 companies basically just told us what size system we could get based on state and federal tax rebate levels. Heard an advertisement for Sunpro on radio and decided to call them; turned out to be a good decision. Kara with Sunpro was extremely informative and had a nice package put together for us to review. She even researched our home and had an idea of how much production we could expect with the recommended solar panels. Even after selecting Sunpro, I called Kara with questions about things I'd heard from others or something I forgot to ask. I never felt like I was a burden and she always returned my calls if I had to leave a message. The complete team with Sunoro were professional and eager to help. Satisfied with new solar system and looking forward to enjoying savings on electric bills.

"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

A vapor barrier keeps moisture out of the crawl space, while insulation reduces the amount of unconditioned air—and sometimes moisture—that enters the space. Coupling a vapor barrier with insulation can help prevent humidity and related moisture damage in a crawl space while also making your home more energy-efficient. Just be sure to use insulation that won’t get damaged from moisture, like rigid foam board or expanding spray foam insulation.

Ideally, you can add new insulation to your existing insulation. However, some circumstances require you to remove old insulation before adding any new insulation: 

  • If the insulation is over 15 years old

  • If the insulation is wet or moldy

  • If it is vermiculite insulation

  • If you see signs of pest infestation

Removing old insulation is best left to a pro who can safely dispose of potential moldy or asbestos-ridden insulation.

While carpet over carpet may provide some additional insulation and soundproofing benefits, it's not as effective as other methods. Layering carpets can add a modest buffer against noise and temperature fluctuations, but it's limited compared to installing thicker carpet padding or using specialized soundproofing materials. For optimal floor insulation and soundproofing, consider alternative solutions tailored to your specific needs and budget, such as adding additional padding or soundproofing underlayments beneath the carpet.

While insulation is required for all exterior walls in a house, it is not typically required for interior walls. Local and state building codes mandate that new construction homes have adequate insulation in exterior walls and ceilings to suit the local climate.

However, there are several benefits to adding insulation to interior walls. It is excellent for sound-dampening between rooms and can help with temperature control by maintaining a regulated temperature in specific rooms and lowering heat transfer between adjacent areas. Insulating interior walls can also contribute to the overall energy efficiency of your home.

Unfortunately, pipes can freeze when exposed to prolonged freezing temperatures, whether or not you have installed insulation covers. Insulation covers, however, are still an excellent idea as they can reduce the chance of your pipe freezing by keeping the pipes closer to the temperature of the water inside the pipe.
