Common Questions About Insulation in Johnson City
How much can I save on energy costs with new insulation?
Homeowners in Johnson City typically reduce their energy bills by 15–30% after proper insulation is installed, depending on the home’s age and structure.

Closed cell spray foam performs well in high heat by creating a strong air and moisture barrier. It helps maintain cooler indoor temperatures.
Can you remove old insulation before installing new materials?
Yes. We provide safe and efficient insulation removal before installing spray foam or cellulose, especially when old materials are contaminated or underperforming.
How long does spray foam insulation last?
Spray foam, when professionally installed, can last over 30 years without degrading or settling.
