"My 85-year-old house needed new insulation after rodents got into the attic. I checked with several companies and Geo-Insulation offered the best results. Owner Tom Porter quickly evaluated the need, provided a quick, no-nonsense estimate, and explained clearly what would be done and what it would accomplish, There was no attempts to up-sale or over-promised. The price was fair and competitive. Tom and his crew arrived on time, added insulation and were done within 90 minutes, including cleanup. Tom even did the paperwork for the City Public Service Energy rebate for insulation and deducted it from the agreed price. Geo-Insulation is a veteran-owned business and Tom provided a small discount for veterans. I'm very pleased with the results and I highly recommend Geo-Insulation."

Insulation FAQs, answered by experts

Minimal but regular checks can ensure maximum thermal performance.

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.

Rigid foam board insulation is one of the safest insulation materials for basement walls. The panels offer a moisture barrier to prevent mold and mildew build-up. At the same time, this material is also fire-resistant, so you don’t have to worry as much about a fire breaking out as you would with spray foam insulation. 

While freezing pipes are less of a concern in warmer climates, pipe insulation can still be beneficial because it helps prevent condensation on cold water pipes, reducing the risk of moisture-related issues like mold growth. It also helps maintain water temperature, reducing the energy needed to heat and cool the water, which can ultimately lower your utility bills.

In some areas, insulation companies require a special license, while some states only require them to hold general contractor licenses. Some municipalities may not mandate any license, although you should always ensure a contractor is fully insured. You can use Angi’s license lookup tool to confirm whether or not an insulation contractor you’re considering holds the necessary license for your area. You can also contact the company for information regarding licenses, certifications, and insurance.
