Black mold in a League City home is handled like any indoor mold, because its color doesn't tell you how risky it is. Stop the moisture first; a homeowner can usually clean less than about 10 square feet, while larger jobs in Texas involve a mold assessment consultant and a separate remediation company. Call the number on this page to be connected with a local mold remediation company in League City.

A creekside, bayside suburb
League City is a large Galveston County suburb about 29 miles from Houston, settled where Clear Creek meets Chigger Bayou, with marinas and resorts along its Clear Lake shoreline. Cowart's Creek and Magnolia Bayou also run through its history. That mix of water and Gulf Coast humidity keeps indoor air damp unless the AC and ventilation are doing their job, and dark mold tends to appear in the same handful of places in local homes.
What to do now
- Trace the moisture. A wet wall, a dripping drain pan or a window that leaks in sideways rain is usually the starting point.
- Stop it before cleaning. EPA warns that mold returns if the water problem isn't fixed.
- Judge the size. Under about 10 square feet is generally a homeowner cleanup; more than that, or growth inside walls, points to a professional job.
- Clean the right way, or not at all. Wear an N-95, gloves and eye protection, scrub hard surfaces with detergent and water, and bag moldy porous items.
- For larger areas, hire two companies. A consultant who holds a TDLR mold assessment license writes the protocol, and a separate company holding a TDLR remediation license does the work.

What you see and the likely cause
| What you see | Likely cause |
|---|---|
| Black rings on ceiling drywall in an upstairs room | Attic AC drain pan overflow or a roof leak |
| Dark spots on the inside of closet doors | Stagnant, humid air in a closed space |
| Growth along the bottom of a wall facing the yard | Rain or sprinkler water against the slab edge |
| Speckled grout and caulk that won't stay clean | A bathroom exhaust fan that doesn't vent outside |
Cost factors
Angi's Houston cost data reports mold removal averaging $2,016, with a typical range of $863 to $3,329. Cost depends on square footage, how much drywall and insulation are replaced, access in two-story homes and whether ducts are involved. Plan on a separate fee for the consultant's protocol and clearance visit. Rebuilding may need a permit from the League City Building Department on West Walker Street, and renters can report unresolved problems to League City Code Compliance through 311 or the online Request Tracker.
