"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."

"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."

"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."

"We would recommend On the Spot. They removed all insulation in attic and basement and replaced it with the appropriate insulation for the house. They covered floors, had a dumpster and left no mess."

Insulation questions, answered by experts

Garden blankets and frost cloths are the best things to use to protect trees and plants from frost. They are made from polypropylene fabric, which is lightweight, breathable, and dries fast. If you can’t get garden blankets or frost cloths before the freeze, you should use lightweight blankets, sheets, or towels.

The amount of insulation you need will vary depending on where you live. Energy Star recommends certain minimum insulation values in different geographic regions. In most cases, however, even adding a little insulation is better than not adding any.

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.

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.

It depends on your needs and preferences, though many homeowners think it is worth it. Not only is blown-in insulation easy to install, but it is highly efficient with thermal regulation. Most types are mold-resistant, flame-resistant, insect-resistant, and, most importantly, completely safe.
