Find the leaks before you fight them.
Your house is breathing through cracks you can't see, and on smoke days those cracks decide how bad it gets inside. A blower door turns 'drafty' into an exact number, then we trace the paths and rank what's worth sealing first.
'Drafty' becomes a number you can act on, with a ranked list of the leaks worth sealing first.
You can't seal what you can't find, and you shouldn't seal what doesn't matter.
Put a number on it
A blower door measures exactly how leaky a building is, so 'drafty' stops being a feeling and becomes a number you can act on.
Find the real paths
With the house depressurized, we find where air actually enters: rim joists, attic hatches, recessed lights, and leaky ducts.
Seal what counts
Not every leak is worth chasing. We rank them so your effort and budget go to the ones moving the most air.
The hidden paths moving air, dust, and smoke through your building.
- Total leakage
A whole-building number (ACH50 and CFM50) you can compare and track over time.
- Entry paths
Where outdoor air, smoke, and dust actually get in, room by room.
- Duct leakage
Air lost between the system and the rooms it was supposed to reach.
- Pressure effects
How exhaust fans and stack effect pull air around the house.
- Comfort drafts
The specific leaks behind the cold room and the hot corner.
- Seal priorities
A ranked list, so sealing dollars go to the leaks moving real air.
Depressurize, measure, trace, then rank the fixes.
-
Set up the door
We mount a calibrated fan in an exterior doorway and depressurize the building to a standard test pressure.
-
Measure the leakage
We record the airflow needed to hold that pressure, which gives your ACH50 and CFM50 numbers.
-
Find the paths
We trace leaks with airflow and, where useful, thermal imaging, so you can see exactly where air sneaks in.
-
Rank the fixes
You get a prioritized sealing list tied to the leaks moving the most air, not a generic checklist.
Turn a drafty house into a number, and a number into a plan.
Get an exact leakage measurement, a map of where air really gets in, and a ranked sealing list so your effort goes where it counts.
