Mold Inspection & Remediation in League City, TX

League City sits between Houston and Galveston Bay and crossed 100,000 residents in 2016, according to the Census Bureau. NOAA's 1991–2020 normals for Galveston, the station in the same county, show about 47 inches of precipitation a year, with September the wettest month at close to 7 inches, at the height of hurricane season.

Clear Creek forms much of the city's northern edge. During Hurricane Harvey in 2017, it reached 500-year flood levels from Highway 288 in Pearland, all through Friendswood, and into League City. More than 2,400 homes flooded in neighboring Friendswood alone. Congress funded a federal flood-reduction project along Clear Creek in 2018, which the U.S. Army Corps of Engineers is designing.

Near the bay, tropical storms bring wind-driven rain that finds its way past roof flashing, windows, and siding, and humid air keeps drying slow. Most homes are slab-on-grade with air handlers in the attic, where condensation and overflowing drain pans are common sources of hidden moisture. The EPA recommends drying wet materials within 24 to 48 hours to keep mold from taking hold.

We found no separate League City price data, so the table uses Houston contractor price guides from 2026 and a 2025 Houston square-foot guide. Storm jobs here often combine mold work with roof or window repair, which another trade bills. Have the consultant's protocol name each area so that every bid covers the same scope, and read our cost guide.

When a storm hits the bay, many homes need help at once, and that is when a license check matters most. Texas requires a mold remediation contractor licensed by TDLR for any removal of 25 contiguous square feet or more, and a separately licensed mold assessment consultant writes the protocol; one license holder cannot do both on the same house.

Since September 1, 2025, the workers themselves need TDLR licenses or registrations. Search names at tdlr.texas.gov, ask for the Consumer Mold Information Sheet, and expect a Certificate of Mold Damage Remediation within 10 days of the passed clearance. File it with your windstorm and flood paperwork: an insurer may not use mold damage that a certificate shows was corrected when making underwriting decisions.

A Galveston County homeowner may need three policies, and mold after a storm can touch all of them. League City is inside the Texas Windstorm Insurance Association's coverage area, where many homeowners policies exclude wind and hail and a TWIA policy covers them instead. Flood water, whether from Clear Creek or a surge off the bay, is excluded by both and needs a flood policy, which FEMA says usually takes 30 days to start.

That leaves the homeowners policy for water that begins inside. The Texas Department of Insurance says most cover sudden, accidental leaks and the resulting mold on damaged items, but not gradual seepage. After a hurricane, photograph the roof, windows, and every wet room before cleanup, and report to each insurer as soon as you can. See does insurance cover mold.
