All homes on Cape Cod qualify for free "air sealing." This new science in energy conservation is deemed so important that they are literally giving it away. If your home is insulated but not air sealed, you are probably paying more than you should for energy costs. It doesn't matter what type of fuel your home uses. If you live on Cape Cod and are a homeowner, you automatically qualify at no cost. No gimmicks or tricks. This is due to funding from the utility companies, and the Davis-Bacon act.
