Mold remediation in Cedar Park, TX

Cedar Park’s February 2021 freeze played out differently from most of the metro. The city water system kept running, and by 9 a.m. on February 19 PEC was reporting zero outages in Cedar Park. So a supply line that split inside an exterior wall kept leaking until someone shut the house valve, and most families then had power to run fans. Fans dry room air. They do not dry wet insulation or the back of drywall inside a closed wall, which is where freeze-year mold hides.

The creeks are the second source. Upper Brushy Creek WCID officials have said flood risk here follows extended drought. Buttercup Creek put water into yards on Riviera Drive during Tropical Storm Hermine in 2010 and again in the late-October 2015 storms. Overnight on August 27 to 28, 2022, 4.66 inches of rain sent Brushy Creek over lawns in the Brushy Bend subdivision. A wall that took creek water and got a box fan instead of a moisture reading is a mold risk. EPA guidance is to dry wet materials within 24 to 48 hours.

The houses are mostly young: Census figures put 63 percent of Cedar Park’s housing units in the 2000 to 2019 build years and 22.5 percent in the 1990s. Age does not stop mold, since drywall paper and carpet pad feed it in a new house too. The city’s inspections follow a slab sequence, and the city says most of Cedar Park sits on the Edwards Aquifer recharge or contributing zone. Limestone under a slab rarely explains the mold we find. A pipe, an appliance or a storm does.

The assessor works for you, so you pick one. TDLR’s public licensee files dated Oct. 26, 2026 list two licensed mold assessment companies with a Cedar Park address. Most of Cedar Park lies in Williamson County, where 30 licensed mold assessment consultants hold current licenses; the Twin Creeks side in the south is in Travis County, where 52 do. A consultant licensed anywhere in Texas can write your protocol; the counts only show how many are close.

Before you sign, check the license number on TDLR’s license search; ours, RCO 1589, checks out the same way. The same files list four licensed mold remediation companies with Cedar Park addresses. We are not one of them.

Do I have to bring a mold assessor in from Austin?

No. TDLR’s Oct. 26, 2026 file shows two licensed mold assessment companies with Cedar Park addresses and 30 licensed consultants in Williamson County. You choose and hire the assessor, and we follow the protocol that consultant writes.

Our power stayed on during the 2021 freeze and we dried the leak with fans. Is that enough?

Often it is. A closed wall with wet insulation can stay damp long after the paint feels dry. Bubbling paint near the floor, a baseboard pulling away, or a damp smell after the house sits closed for a weekend are reasons to get a moisture reading. Normal readings mean there is nothing to remove.

We live on Riviera Drive by Buttercup Creek. Should we wait for the city’s drainage project?

Not for mold that is already there. The Riviera East drainage improvements are in design, with construction anticipated to start in fall 2027. Existing growth comes out the same way whether the creek work is done or not. Until then, after a storm puts water against your walls, get the wet carpet and pad out and the area read inside the 24 to 48 hour window.

How will I know the remediation passed?

At 25 contiguous square feet or more, the independent assessor checks the area against the written protocol after we finish, and a pass is followed by your certificate. On smaller jobs you get our photos and final moisture readings.
