In Bellaire, mildew on grout, window sills or a closet ceiling is usually surface growth you can clean yourself while bringing indoor humidity down. Spotting low on walls in a home that has flooded, or growth that has soaked into drywall and carpet, calls for a professional look.

Bellaire homes and moisture
Bellaire is a small, mostly residential city of about 17,200 people, roughly 6 miles from downtown Houston and surrounded by Houston and West University Place. Many of its original post-World War II houses have been replaced with new ones. Brays Bayou is the big local water risk: much of the city lies in the 100-year floodplain, and over 1,400 structures flooded in Tropical Storm Allison, more than 200 in the 2015 Memorial Day storm and over 2,000 in Harvey.
What to do now
- Look at where it is. Grout, tub caulk and window glass are classic mildew spots. Spotting along the bottom of walls in a home that has taken on water is a different matter.
- Measure it. EPA says areas under about 10 square feet are usually a homeowner job.
- Find the moisture. Check the bath fan, the AC drain line, under sinks and around windows.
- Clean small areas properly. Use detergent and water on hard surfaces, dry them completely, and wear gloves, eye protection and an N-95.
- Throw out what can't be saved. Moldy ceiling tiles, bath mats and carpet often need to go.
- Bring in a professional if it comes back, is large, or sits inside walls.

What you see and what it usually means
| What you see | Likely cause |
|---|---|
| Black dots along shower grout | Steam that lingers after showers; a fan too weak or run too briefly |
| Fuzzy film on closet walls and stored shoes | Little air movement and high indoor humidity |
| Spotting around ceiling vents | Cold supply air meeting humid room air, or sweating ducts |
| Stains and spots low on walls after heavy rain | Water that reached the wall from a flood or slab-edge leak |
What affects the cost
Angi's Houston cost data reports mold removal averaging $2,016, typically $863 to $3,329. Cost rises with the area involved, whether drywall or flooring has to come out, and access. Texas requires the assessor who writes the cleanup protocol and the company that does the work to be separate on the same project, so plan for two bills on a professional job. Rebuilding after cleanup goes through City of Bellaire Development Services, and the city requires a permit, issued free, for all flood-related repairs before work begins.
