"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."

"Nick was very professional and very knowledgeable. He explained to me my mold problem and how he would handle the situation. The crawl space looked amazing and was mold free once the job was complete. Excellent company would recommend and definitely use again."

"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

In some cases, yes, insulating an unheated garage can lead to mold and mildew. The issue with insulating a garage is that the interior will warm up and cool down more slowly than the exterior air, which can cause condensation inside the space. Where there is moisture, there is likely to be mold and mildew over time. Installing a vapor barrier can help avoid moisture and mildew problems in an insulated garage.

One of the disadvantages of soffit vents is they can bleed warm air from the attic during winter, resulting in slightly higher energy bills and a colder house. There are ways to mitigate this effect—mostly just closing the vent in the fall. What’s most important is your attic is ventilated to some degree in the winter.

Traditional clapboard siding, particularly with panels made from wood, is not a significant insulator on its own. However, you can keep your home cooler in summer and warmer with "insulated clapboard siding," which is a type of vinyl clapboard siding with a built-in foam insulation. Consult a local siding contractor to determine whether insulated siding is right for your home.

A plastic vapor barrier should completely cover your basement to prevent water from penetrating through the walls. This typically goes before installing insulation to prevent moisture from building up and becoming trapped on the inside of your insulation, where it can collect and lead to mold damage. Installing insulation after the vapor barrier allows for any moisture to exit the walls for better ventilation.

If the temperature outside is around 90 or 100 degrees with the sun beating on your home’s roof, it’s common for the attic temperature to reach 150 degrees or more. This excessive heat shows the importance of having a radiant barrier in place along with insulation. The radiant barrier reflects the heat entering the attic back upward, keeping your home’s temperature more consistent.
