Mold Removal & Remediation in League City, TX

A creekside city by the bay

League City is a large Galveston County suburb about 29 miles from Houston, first settled where Clear Creek meets Chigger Bayou, with Cowart's Creek and Magnolia Bayou also part of its story and marinas along the Clear Lake shoreline. That much nearby water, plus Gulf Coast heat and humidity, means moisture is never far away. Most mold calls, though, start inside: attic air handlers, sweating ducts, bathroom leaks and roof damage after storms.

What to do now

1. Stop the source. Turn off the water to a leaking fixture, clear a clogged condensate line or cover a roof opening.
2. Dry fast. EPA says wet materials should be dried within 24 to 48 hours to prevent growth.
3. Leave the mold alone. Don't sand, scrape or paint over it; that spreads spores or hides the problem.
4. Turn the AC off if ducts are suspect. EPA warns that running a contaminated system can spread mold.
5. Get the assessment first. Texas requires a consultant's protocol before a hired remediation job, and a different company for the removal.
6. Renting? Notify your landlord in writing. League City's Code Compliance takes reports through 311, the online Request Tracker or 281-554-1480.

What you see and the likely cause

Cost factors

Angi's Houston cost data lists typical mold removal at $863 to $3,329. HomeGuide's 2026 national figures put bathrooms at $500 to $2,000 and partial attics at $1,500 to $6,000. Size, removal of drywall and insulation, attic access, duct involvement and the separate consultant's protocol and clearance fee shape your total. Because so much of the work happens in hot attics, jobs scheduled in cooler months can be easier to staff and finish. Rebuilding afterward goes through the League City Building Department at 500 W. Walker St. (281-554-1429). Before work starts, look up both companies on TDLR's license search and read the protocol so you know the clearance criteria.
