Most mold and mildew in a Porter home grows on surfaces that stay damp, such as bathroom ceilings, grout, closet walls and AC registers, and a homeowner can clean small hard-surface areas. When the growth is large, has soaked into drywall or carpet, or keeps returning, the moisture source needs fixing and professional cleanup is the safer route. Call the number on this page to be connected with a local mold remediation company in Porter.

What to expect when you call
The line connects you with an independent mold remediation company serving Porter and the 77365 area. Before the referral, you'll be asked a few plain questions: which room, which surface, how much growth and whether it has come back after cleaning. The company you reach may then:
- Ask for photos or schedule a visit to look at the area.
- Use a moisture meter on walls, cabinets and flooring near the growth.
- Look at the bath fan, the AC drain line and nearby plumbing.
- Explain whether the job is surface cleaning or removal of damaged material.
For a larger project, Texas requires a mold assessment consultant who holds a TDLR license to write a protocol first, and a different company to do the cleanup.
What moves the price
National ranges (HomeGuide, 2026) list bathroom mold work at $500 to $2,000 and small areas of 10 to 100 square feet at $500 to $1,500, with labor at $75 to $120 an hour. Greater Houston prices depend on how far the growth has spread, whether tile, drywall or cabinets come out, how hard the area is to reach and whether two companies are involved. Fixing the leak or the AC is billed separately by the right trade.

Porter conditions
Porter has no official boundaries; it is an unincorporated community in southeast Montgomery County loosely defined by its ZIP code, with I-69, the Grand Parkway and FM 1314 running through. Hurricane Harvey dropped about 36 inches of rain on Montgomery County, and the sheriff reported Peach Creek out of its banks. Homes that took water in that storm, or in later heavy rain, can hold dampness in walls and subfloors. Day to day, the AC runs most of the year and carries the whole drying load, so bathrooms and closets with little airflow stay damp. Rebuilding after cleanup goes through the Montgomery County Permit Department under Environmental Health, which also handles floodplain permits for substantially damaged homes.
Checklist before anyone arrives
- Leave the growth as it is; don't paint or caulk over it.
- Note whether the spot is worse after showers, rain or AC cycles.
- Keep pets and children out of the room.
- Find the attic hatch and the AC air handler so they're easy to reach.
- Verify the company on TDLR's license search.
