Duct sealing
Mastic and metal tape on leaky joints and boots, so the air you pay to cool reaches your rooms instead of the attic.

How it works
Numbers, not guesses
A blower door is a calibrated fan mounted in an exterior doorway. It pulls air out of the house to a standard test pressure of 50 pascals, then measures how much outside air leaks back in through gaps and cracks.
A duct leakage test pressurizes your duct system to measure how much air escapes before it reaches your rooms. We also take basic air quality readings during the visit.
Testing before and after insulation or duct sealing shows exactly what changed.

How the job goes
From first call to finished
- 01
Set up
We close exterior doors and windows, open interior doors and set the house to test conditions.
- 02
Blower door test
The fan holds the house at 50 pascals while we measure leakage and look for leaks.
- 03
Duct and air tests
We test the duct system for leaks and take air quality readings.
- 04
Review the report
We go over the results and what to fix first, in writing.
How long does testing take?
Plan for a few hours, depending on the size of the home and which tests you choose.
What does ACH50 mean?
Air changes per hour at 50 pascals. It's how many times the air in your house is replaced each hour while the blower door holds the test pressure. Lower means a tighter house.
Do I have to hire you for the fixes?
No. The report is yours to keep whether you hire us or not.
Should I be home during the test?
It helps. We can show you leaks as we find them and walk you through the results at the end.
