Newer Irvine construction is built tight for energy efficiency. That’s good for your utility bill and bad for airflow: steam from showers, moisture from cooking, and humidity from the laundry room have nowhere to go if the ventilation isn’t up to the job. Add the marine layer that rolls in off the coast most mornings from May through August, and even a house built five years ago is carrying more moisture than most homeowners realize. Finding out where that damp air is settling is exactly what testing is for.
Slab leaks are the other classic Orange County problem, and Irvine sees plenty of them. Copper pipe runs through the concrete slab under the house, and when it fails, the first sign is usually a damp line along a baseboard or a musty patch in the carpet with no water visible anywhere nearby. Air sampling, surface sampling, and moisture readings tell you whether you’re looking at a slab leak, a roof leak from one of winter’s storms, or condensation building up on ductwork tucked into the attic.
