Services For Homeowners



Leaky homes are hard to heat and hard to cool. The only way to know whether your home is leaky or tight is to measure its air leakage rate with a blower door.


A blower door is a tool that depressurizes a house; this depressurization exaggerates the home’s air leaks, making the leaks easier to measure and locate.

An energy-efficient house must be as airtight as possible. Many older U.S. homes are so leaky that a third to a half of the home’s heat loss comes from air leaks.

There is no such thing as a house that is too tight. However, it’s also true that there is no such a thing as an airtight house. Every house leaks, and that’s why we perform blower-door tests — to measure a building’s leakage rate.

There are at least two reasons to conduct a blower-door test on an existing house: to determine how leaky it is, and to help locate and fix the leaks. When a blower door is used to help an air-sealing contractor locate and fix leaks in an existing house, the procedure is called “blower-door-directed air sealing.”

Atlanta Blower Door will work with homeowners who would like to test the envelope tightness of your home and offer solutions to reduce leakage and save money on energy costs. In additions to duct blaster and blower door testing, we will offer an evaluation regarding the energy efficiency of your home and work with you to achieve a tighter envelope thus reducing air leakage and lowering energy costs.

Benefits of Testing

  • Reduce energy consumption due to air leakage
  • Avoid moisture condensation problems
  • Avoid uncomfortable drafts caused by cold air leaking in from the outdoors
  • Determine how much mechanical ventilation might be needed to provide acceptable indoor air quality

Where Air Leaks

Did You Know?

The average home has air leakage equivalent to a two-foot-square hole.

That’s the same as leaving a medium-sized window wide open 24 hrs a day.
