Before and After Pictures from Brewster

This Brewster basement had traditional fiber glass insulation that was poorly installed and was not controlling the heat and cool air throughout the home properly. This caused the home to have uneven temperatures and a high electric bill. They wanted a solution to make sure air leakage is totally prevented. They decided to give Connecticut Basement Systems a call to help find them a solution.

The experts at Connecticut Basement Systems installed Spray Foam on the ceiling of the basement. Spray Foam was the best option for this home because it effectively fills voids and odd-shaped spaces, meaning that you will always get total coverage. This product will stop air leakage, making it effective at saving the home owners money through their electricity bill. Lastly, Spray Foam will not absorb moisture or lose R-value like fiberglass. 

Now that their basement ceiling is completely Spray Foamed, these happy homeowners enjoy consistent temperatures throughout the home and a lower electric bill!
