The blower door test
A big fan and a screen go on your front door. It pressurizes or depressurizes the house and measures how air-leaky the whole thing is. One number for the entire home, not a guess.
You'll know: how leaky your house actually is.
Confirming your thermal scan
Thermal imaging shows you where heat is getting in. The full energy audit shows you how leaky the entire house is, and exactly where to seal it.
Derek or his team will reach out within 24 hours to schedule it.
$199 TOTAL
That's the full audit, with the $49 you just paid included.
We'll confirm your upgrade on the scheduling call and charge the remaining $150 to the card you used for your $49 scan. The full $199 is credited toward any service you choose with Capstone.

Whole-Home Energy Audit

A big fan and a screen go on your front door. It pressurizes or depressurizes the house and measures how air-leaky the whole thing is. One number for the entire home, not a guess.
You'll know: how leaky your house actually is.

With the fan running, Derek walks every door, every window and the attic with a smoke pen. Where the smoke bends, air is moving. Each leak gets found and marked on the spot.
You'll know: which windows and doors leak, and exactly where.

The thermal scan you already booked, now done with the blower door pulling air through every gap, so the leaks light up on camera. Ceilings and exterior walls.
You'll know: where the heat is getting in.

Ductwork, ventilation, air sealing and insulation, all checked while Derek is up there. Is the leak really your attic, or is it coming from somewhere else in the house?
You'll know: whether the problem is the attic or somewhere else.
