"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."

"James and his crew did a phenomenal job with the insulation job! His communication was great. Very honest and upfront about what can and can’t be done. No trying to finesse an upsale or anything like that. I'm very glad we went with James and I'd highly recommend him to anyone looking."

"Reeds reinsulated our attic of 70 years. The former insulation had settled well below the rafters. The work crew vacuumed out the old, sealed around all openings to lights, fans, etc and then blew brand new fiberglass insulation to knee depth. We now have lofty, R-40 rated protection in a 2600 sq' house that heats evenly through out. Reeds will return to encapsulate our crawl space in one month!"

Insulation FAQs, answered by experts

If you have access to the foundation walls, adding spray foam insulation to your existing unfinished basement or crawl space is straightforward. Replacing existing insulation in your unfinished attic space is possible after removing the old insulation. However, spray foam insulating an existing wall after the drywall is in place isn’t possible unless you remove most of the drywall.

Insulating an unheated garage can still be worth it. For instance, insulating an attached garage can help with heat loss from your house in general, and it can also make it easier to store electronics in your garage without worrying about them being exposed to extreme temperatures.

If you use your detached garage as a workspace, insulation can still make a difference. Plus, you can use space heaters and a window unit AC to help condition the space while you work without installing heating.

Yes, even though frost-free and freeze-proof faucets are designed to withstand winter weather, it is still recommended to cover them with an insulated cap, especially during periods of extreme cold. These faucets work by keeping excess water inside the home's heated space and using a downward slope to drain, but this protection can be compromised. For the faucet to work correctly, you must always disconnect any attached hoses before temperatures drop below freezing, as a hose can trap water and lead to freezing. Ultimately, covering all outdoor faucets, even freeze-proof models, is the best way to prevent frozen and burst pipes.

Minimal, mainly occasional checks for damage or mold in extreme conditions.

Yes, insulating ductwork in a crawl space is a worthwhile investment, especially if you live in a colder climate or run your air conditioning for most of the year. Uninsulated ducts can lose up to 30% of their heating and cooling efficiency, which can significantly impact your electricity bill. The project is a relatively small investment and typically only takes a few hours. It's a particularly simple add-on if you are already hiring someone to insulate the entire crawl space. An added benefit is that insulated ducts put off less hot or cold air, making them less attractive to pests.
