Leaky or damaged ductwork in a Renton 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.
Ductwork is often the overlooked half of a comfort complaint. 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.
Every joint gets mastic and a proper mechanical fastener, never the cloth tape that peels off in a season or two.
We take a pressure reading before we start and another right after, so the improvement is a number, not a promise.
We photograph what we find before repairing it, especially useful for insurance or landlord disputes.
Six issues that come up on most inspections.
Testing comes before sealing.
