Black mold in a Webster home is handled the way EPA recommends for any indoor mold: stop the moisture and remove the growth, including porous materials it has ruined. Small hard-surface patches are a homeowner job, and larger or hidden growth needs a Texas mold assessor and a separate remediation company. Call the number on this page to be connected with a local mold remediation company in Webster.

Local conditions in Webster
Webster is a city of about 12,500 people in the Clear Lake area, roughly 26 miles from downtown Houston, closely tied to NASA's Johnson Space Center and the high-tech work around it. Clear Creek forms its southeastern border and the Harris County and Galveston County line. Like the rest of the bay area, Webster homes deal with heavy rain, humid air and long cooling seasons. Dark mold usually starts where one of those gets inside: a roof or window leak during a storm, condensation on attic ducts, a clogged AC drain line, or water that entered at floor level during a heavy downpour.
Clean it or call?
| Where the black growth is | Typical answer |
|---|---|
| Shower grout, tub caulk, window glass | Clean it; run the exhaust fan longer |
| Painted drywall, small and dry, leak fixed | Homeowner cleanup is allowed in Texas |
| Drywall that is soft, stained through or bulging | Removal by a remediation company |
| Inside the air handler or on many vents | Turn off the AC and get it assessed |
| A rented apartment | Written notice to the landlord |
Color plays no part in the decision. EPA treats every indoor mold the same way, and a dark color does not tell you which mold it is or how risky it is. EPA also says that when mold is visible, sampling is usually unnecessary, so a lab report naming the species rarely changes the plan. Spend the money on finding the moisture and removing the growth properly.

Signs it has gone further
- A musty odor that lingers after the room has been cleaned
- Growth that returns a few weeks after wiping
- Bubbled paint or loose tape seams on the ceiling
- Dark specks on supply vents in more than one room
Timing and next steps
Storm season and the hottest summer months bring the most water and condensation into Webster homes. EPA says to dry wet materials within 24 to 48 hours. When removal is needed, a mold assessment consultant who holds a TDLR license writes the protocol, a separate remediation company does the work, and the consultant returns for clearance. Rebuilding afterward goes through the City of Webster Building Division, which handles building permits and inspections and has adopted the International Property Maintenance Code.
