The Basics of Air Sealing

When it’s cold, too much air may enter the house through cracks and openings causing you to spend a lot more running your HVAC unit. On the other hand, when it’s warm, you may not get enough fresh air and this affects your indoor air quality. Additionally, air leakage can result in moisture issues and mold eventually compromising the health and structural integrity of your home. That’s why contractors recommend sealing any cracks and openings in your home using the best air sealing techniques.

If you notice daylight around a door or window frame, it means there’s a possible air leak.

Pressure Testing

Pressure testing which is commonly referred to as the door blower test is done to determine air leaks in a given space. Air flow is recorded using a device known as a manomenter and the points of air leaks are exposed through cracks and holes that are present in the building envelope. Finding the air leaks is important as it helps you to determine the beast sealing techniques that will be a good investment.

Caulking and Weather Stripping

Once you have discovered that there are possible airleaks in your home the next logical step is to seal them and do everything possible to ensure it’s as tight as possible. Consider replacing any old doors and windows with better ones and weather-stripping them. Caulking the doors and windows that leak air can also make a big impact.
