Air Sealing

Air sealing is a great way to save energy and money


While some of the air leaks in your home are visible to the untrained eye — around old and untreated doors and windows, for example — much of the average home's air leakage takes place in areas you don't see. A lot of it takes place because of something called the stack effect, or chimney effect, which works like this: cold air infiltrates your cellar through leaks and cracks in the foundation and walls, and begins rising. It works its way up through the floors and/or walls, then up into your attic through structural defects, holes in your ceiling, recessed lighting, leaky duct work, the furnace flue, the plumbing stack, or a poorly sealed attic floor. By performing air sealing, we are able to reduce the chimney effect, working from the basement to the attic, and increasing efficiency. 

Additionally, air sealing is incredibly important when examining a home's insulation. Insulation will only work properly if the area around it is sound and can keep heat. If the area around one's insulation is blustery and drafty, it negates the impact that having insulation could potentially have. Temperature control — which is the purpose of insulation — goes right out the window (literally) if a house is not adequately sealed.



Air that leaks through your home's envelope − the outer walls, windows, doors, and other openings − wastes a lot of energy and increases your utility costs. A well-sealed envelope, coupled with the right amount of insulation, can make a real difference on your utility bills.
