Mold removal in a large Bee Cave house starts at the thermostat. A return sitting in or near the work area pulls whatever is in that air into the trunk line and delivers it to every room on the zone, which is how a leak in a downstairs powder bath ends up smelling like a problem in an upstairs bedroom. The S520 standard treats the air handler as part of the containment for exactly that reason, and so do we. The system goes off, the returns and registers inside the barrier get sealed, and only then does anything get opened.
The leaks themselves are usually small and old. A shower pan or a tile wet wall in a secondary bath that gets used twice a year, an angle stop weeping behind a vanity, a supply fitting behind a run of cabinetry. In the newer builds around The Uplands and Rocky Creek, two or three zoned systems mean the smell can surface a long way from the water, so we chase the moisture instead of the odor.
Containment, and the parts of it nobody sees
The plastic barrier is the visible half. The rest is pressure and air path: negative pressure inside the containment so air moves in and never back out, HEPA scrubbers running continuously, filtration on the exhaust, and a taped route for material to leave the house without touching a finished surface. Porous material comes out bagged, sound framing gets HEPA-vacuumed and treated, and the wet cavity behind it dries to a meter reading rather than to the touch. Skip that last step and the mold remediation buys you one season.
- Air handler off, returns and registers inside the barrier sealed before the first cut
- Negative pressure held inside the containment with HEPA scrubbers running throughout
- Porous material bagged out, sound framing HEPA-vacuumed and treated
- The leak behind it dried to a meter reading, then re-read the following day

When growth follows a water loss your policy covers, the removal usually rides on the same claim, and Austin Flood & Leak Restoration writes it that way: photos before the barrier goes up, readings by room, and a scope your adjuster can price. Coverage is the carrier's decision. So is the smaller judgment we owe you honestly, which is when a patch is small enough that you do not need us at all. Call (512) 271-5099.
