League City at a glance
League City is a large Galveston County suburb of about 114,000 people, roughly 29 miles from Houston along I-45, settled where Clear Creek meets Chigger Bayou. Cowart's Creek and Magnolia Bayou are part of its story too, and waterside resorts and marinas line its Clear Lake-area shoreline near South Shore Harbor. The commercial mix runs from the older Main Street area around Butler Oaks to newer centers on FM 646 and SH 96. Bay humidity, flat terrain and long cooling seasons put steady moisture pressure on every building type.
What to do now
- Stop the source. Roof leaks, plumbing, condensate pans and storefront door seals are the usual suspects.
- Dry what you can within EPA's 24 to 48 hour window, and pull soaked carpet and ceiling tile.
- Isolate the system. Turn off an air handler you suspect is contaminated so it doesn't carry spores to other suites.
- Know the threshold. At 25 contiguous square feet or more in a business, or in apartments with 10 or more units, the removal needs a TDLR remediation license holder.
- Hire in order. Assessment consultant first, a different company for the removal, both checked on TDLR's license search.
Signs and likely causes
| What you see | Likely cause |
|---|---|
| Musty smell in a marina office or ship store | Bay humidity and little air exchange |
| Ceiling spots in an upper-floor apartment corridor | Roof or rooftop unit leak |
| Dark rings around supply vents | Cold air meeting humid indoor air |
| Stained drywall below a window line | Wind-driven rain getting past the frame |
Cost factors
The protocol defines what comes out and how, and that sets the price. Angi's Houston cost data for mold removal reports an average of $2,016, typically $863 to $3,329, and HomeGuide's 2026 national range for a large area of 300 to 1,000 square feet is $6,000 to $15,000. Two companies mean two fees under Texas law. Rebuilding goes through the League City Building Department at 500 W. Walker St., 281.554.1429. Tenants can report unrepaired problems to Code Compliance through 311, the online Request Tracker or 281-554-1480. The Galveston County Health District does not handle mold.
