Blower Door Testing in Royalton, MN
Blower door testing to find and measure air leakage.
Measure the Leaks, Then Fix Them
A blower door is a calibrated fan that depressurizes the building and measures exactly how leaky it is - in numbers, not guesses. New construction in Minnesota uses it to prove code air-tightness. For an existing home, it finds where the heat is actually going before you spend on fixes.
We run blower-door tests as a standalone service and as the before-and-after proof on air-sealing and insulation projects. Paired with the test, leak-finding shows the real culprits - rim joists, attic bypasses, hatches, duct penetrations - so the budget goes where the air is moving.
For builders, we test to your inspection schedule and deliver the documentation your code official needs. For homeowners, it turns "the house feels drafty" into a number and a ranked fix list.

Common Questions
What does a blower door test tell me?
How leaky the building actually is, as a number rather than a guess, and where the leaks are. For an existing home it shows where the heat is going before you spend money on fixes.
Is a blower door test required for new construction in Minnesota?
Minnesota code requires verified air-tightness on new homes, and the test is how it is proven. We test to your inspection schedule and deliver the documentation your code official needs.
Can you test before and after air sealing?
Yes, and that is the most useful way to buy it: a baseline number, the air-sealing work, then a second test showing what changed.
