"The company rep came out as scheduled and conducted a thorough and professional estimate for the added insulation. Then the installers came out and again did an outstanding job adding insulation to our attic. They worked well as a team and did an excellent job."

"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."

"Eddie fully explained the benefit of the planned level of insulation for our attic, uses quality Owen's Corning fiberglass blown in insulation and recommended adding an roof vent attic fan to remove heat/moisture in the summer and moisture in the winter. Currently, we have passive eve vents and roof ridge vent. Cooling inside of the roof with air flow should help extend the life of the shingles by removing stagnant hot air. We chose an electric roof vent fan rather than solar because of the # of cloudy days in our area and humidity. Everything was done quickly on scheduled time, all contacts were professional, kept our home as clean as possible and swept up loose insulation. Pricing was very competitive plus we qualified for TVA energy rebate."

Insulation FAQs, answered by experts

When looking for a company who installs insulation, your best bet is usually to work with an insulation contractor or professional insulation company. If you can't find a local insulation company, working with a general contractor can be another option. No matter who you hire, always confirm that they have experience.

If you need to insulate behind finished walls, the best option will likely be to have an insulation professional install blown-in insulation. The installation requires small holes cut in your wall, after which the installer can blow loose-fill insulation into the void. After the installation, you’ll have minor drywall patching, which shouldn’t cost more than $100. Compared to ripping down the existing drywall, using a different type of insulation, and replacing and finishing the drywall, this should save you hundreds or even thousands, depending on the size of the room you’re insulating.

Structural insulated panels and rigid foam boards have the highest R-value of any insulation that contractors commonly use, with R-values reaching up to around 8.0. These types of insulation are best in extremely cold climates, but they’re generally preferred for new construction, as they can be challenging to retrofit. Blown-in and loose fill insulation provide the next best insulative value, provided the installation is done properly. It’s important to choose an insulation type that meets your needs based on climate, as maximizing R-value may not always be financially worthwhile if you live in a moderate climate.

DIY installation is not recommended, as professionals ensure even distribution, proper sealing, and compliance with building codes.

Fiberglass is considered a favorite garage insulation choice due to its combination of affordability, ease of installation, and overall effectiveness. Fiberglass provides good thermal resistance, helping regulate garage temperatures and minimize heat transfer. Additionally, fiberglass is moisture-resistant, reducing the risk of mold or mildew formation.
