Leaky or damaged ductwork in a San Lorenzo attic or crawl space can waste a large share of conditioned air before it reaches a vent. We test static pressure and leakage directly rather than guessing based on appearance on every visit.
San Lorenzo homeowners often assume duct problems when comfort is off but equipment seems fine, and they're often right — disconnected sections and torn insulation are common in attics and crawl spaces. We inspect the full run, not just the sections near the equipment, since damage tends to hide exactly where it's hardest to see.
What every duct assessment includes.
Leakage gets measured with a duct blaster test.
Not just visible sections.
What we use is meant to last, not just look sealed on day one.
We take a pressure reading before we start and another right after, so the improvement is a number, not a promise.
Evidence, not just our word for it.
The most common duct problems we find and correct.
We measure leakage, then seal every joint with mastic rather than tape.

What people ask before we test their ductwork.
A duct blaster test gives the real number.
Mastic sealant is what actually holds up for the long haul.
Significant leakage in attic or crawl space runs can waste a meaningful share.
It is more than cosmetic — chewed insulation and punctured duct walls both leak air and can pull contaminants into circulation.
The fix gets done the same day we find the problem, in most cases.
Longer for extensive resizing.

We will flag anything unusual before starting.
