This homeowner called us because they were cold in the winter temperatures and desired a warm and cozy home. When they were paying to run their heater, it was not maintaining a warm temperature. Of course, most of us know that hot air rises. When an attic isn't properly sealed, there is essentially a hole where the heat is escaping. We sealed all of these attic floor penetrations and sealed his six can light with our rock wool covers. Give us a call and we will ensure that the job is done correctly.
