We had an older home and we were trying to decide if we should remodel and expand or sell and get a new home. Part of that was looking into better insulation and sealing, as we had a lot of air leaks that were letting in dust and pollen and adding to our son's allergy problems. We called Entergis who came out and did a complete air leakage test for us. Greg and his team were able to give us a lot of good advice and with all the information we were able to make the informed decision to sell our home.

Once we bought our new house we called Entergis again and they came and sealed up some air leaks we had. There was nothing huge, but Greg found several big air leaks we would have never known to look for, like under the bathroom sink and behind the dryer. The biggest improvement I saw was in the hallway where the attic access is located. Before Entergis came out you could feel the cold air rushing up into the attic, but after they installed a nice attic door insulator the air stays in the house like it should. This has helped lower our power bill and make the house more comfortable. Plus there is the added benefit that this puts less strain on the A/C unit, meaning we will get more life out of it.

If you are thinking of remodeling, selling, or buying a home you should give Entergis a call.
