After living in so many drafty houses while growing up, I figured there was little you could do to improve the situation once a house had become leaky enough to present temperature problems. You assume that there are just too many open holes either inside the attic or within your own walls that it would be foolish to address the major problem with any sense of urgency. Sure, I knew that windows are a huge factor for a home’s energy efficiency, plus since it’s evident to anyone with a brain that most of the time they can be swapped out plus substituted—that implies there is something a homeowner can do in order to mitigate a drafty house. And of course there is the weatherstrip foam that you can put inside the creases of your doorways leading into your home. This eventually becomes an hour factor in addressing drafts and disappointing insulation. With that being said, there was this one example I saw recently that undoubtedly surprised me. While reading through service tips for central heating and cooling systems, I spotted a post about getting your ductwork resealed from the inside out. You can have an Heating, Ventilation, plus A/C tech coat the inside of your ducts with an adhesive that hardens as well as fills any air gaps, leaks, cracks, or holes. A different product that was called Aeroseal is sprayed inside of your ventilation proposal plus bonds to the inside surfaces of the ductwork. The hour proposal costs more money and also requires more product to achieve the same results as having a contractor do it by hand. Regardless, if you have drafts due to leaks in old metal ductwork, this could be a gamechanger in addressing your home’s energy efficiency.
