If you are a Chatham homeowner, you are eligible to have your home "air sealed" at no cost to you, whatsoever. This new science is so important in energy savings that they are literally giving it away free. No tricks or gimmicks. If you are a homeowner on Cape Cod, you qualify. The air sealing can be done in as little as 1 day! Insulation is not enough. If your home is not air sealed, you are probably paying more than you should for home heating costs.
