How to Test Air Tightness of House

One way to test the air tightness of your house is by doing a smoke test. To do this, you will need to close all doors and windows in the house and turn off any fans or other ventilation systems. Then, light a stick of incense and hold it near where you think there might be leaks in the door or window frames.

If you see smoke coming through, that means there’s a draft.

  • Make sure all doors and windows are closed
  • Turn off all exhaust fans and any other devices that introduce outside air into the house
  • Light a stick of incense and hold it near doors, windows, electrical outlets, and other places where air might be leaking into the house
  • If the smoke from the incense is drawn into the house, there is an air leak

How Do You Know If Your House is Air Tight?

There are a few key indicators that your home may not be as airtight as it could be. For example, if you can see daylight around doors and windows or feel a draft when walking by them, those are both good signs that there are gaps in the sealant around those openings. Another way to tell is if your utility bills for heating and cooling seem unusually high.

This could be because conditioned air is escaping from your home, making your HVAC system work harder than necessary to maintain the desired temperature inside. To really know for sure, you can hire a professional energy auditor to conduct a thorough assessment of your home’s energy efficiency. They will use special equipment to test for leaks in the envelope of your home and provide recommendations for how to improve its airtightness.

Making even small changes can have a big impact on your energy bills and comfort level at home, so it’s definitely worth looking into!

How Do You Perform an Air Tightness Test?

Understanding Building Air Tightness | Part 1


It is very important to test the air tightness of your house in order to ensure that it is energy efficient. There are a few different ways that you can do this. One way is to use a piece of tape and a straw.

Put the straw in your mouth and seal it with the tape. Then, go around your house and try to find any cracks or openings where air might be leaking out. Another way to test for air tightness is to turn off all of the fans and exhausts in your house and then light a candle.

Move the candle around all of the windows and doors to see if the flame flickers. If it does, then there is an air leak.
