In attempting to enhance home performance, it's important for Northern VA, Maryland and Washington, DC homeowners to gain a basic understanding of home efficiency.


Your home is a complex system made up of a number of different working parts, all of which combine to allow the home to function as a cohesive unit. Think of the home as a vehicle. If the engine overheats and the problem isn't dealt with, it's going to affect practically every other aspect of the vehicle. The same goes for the home and how it utilizes energy. This whole-home approach to looking at and improving how your home consumes energy is known as "home performance."


One of the most important combinations of factors that affect building science and how the home works is insulation and air sealing. Insulation plays a huge role in heat retention, whereas air sealing takes care of any cracks and gaps that allow outdoor air to infiltrate the home and conditioned indoor air to escape. On their own, each of these two practices can help to maintain comfortable interior temperatures and keep air quality from suffering, but studies have shown that the effectiveness of insulation drops by 50% without the assistance of air sealing.

As an analogy, think of air sealing as a windbreaker and insulation as a sweater. If you're outside on a windy day, the sweater is only going to keep you warm if you have a protective layer surrounding it to keep the cold at bay. At the same time, the windbreaker alone wouldn't be sufficient to stop the chill entirely. The same can be said for air sealing and insulation; each needs the other in order to function in the most efficient way possible.

Looking for Duct Sealing? Did you know...

There is a substantial amount of energy loss when your HVAC system works overtime to make up for leaks and gaps in your ductwork. In addition to increased energy bills, the unnecessary strain on your system can significantly shorten its lifespan or lead to costly repairs. Air duct leaks can also create indoor air quality issues by allowing dust, allergens, and other pollutants easy access to the air circulating through your home. Having properly sealed ducts keeps these pollutants out of the air you breathe and balances temperatures, leaving your home feeling more comfortable.


Scott and the team did soundproofing work on what will be our child's nursery -- we live in a condo and could hear almost everything from the neighbors. The entire team was polite, kind, and most importantly, really effective.
