Most mildew in Webster homes is a surface film on grout, caulk, windows or closet walls, and the homeowner can usually clean small areas while bringing humidity down. Large areas, growth in drywall or carpet, or mildew that returns quickly after cleaning suggest a moisture problem a professional should find.

Local conditions in Webster
Webster is a city of about 12,500 people, roughly 26 miles from downtown Houston, closely tied to the Clear Lake area and its high-tech industry, with NASA's Johnson Space Center nearby. Clear Creek forms Webster's southeastern border along the Harris and Galveston county line. Creek and lake humidity, a long cooling season and heavy Gulf rains are the main sources of indoor moisture. Many homes and apartments here rely on AC equipment that can sweat at vents, overflow at the drain pan or leave rooms humid when it cycles on and off too quickly.
Clean it yourself or hire it out?
| Where the mildew is | Homeowner | Company |
|---|---|---|
| Grout, tub caulk, glass | Clean with detergent and water | Rarely needed |
| Closet walls and stored items | Clean, then improve airflow | If drywall is stained through |
| Ceiling near the AC unit | Clean a small patch after fixing the drain | If it spreads or the drywall sags |
| Inside walls or under flooring | No | Yes |
| Larger than about 10 square feet | EPA advises against | Yes |

Signs worth acting on
- Mildew that returns within weeks of a careful cleaning
- A musty smell when the AC starts up
- Paint peeling near tubs, showers or exterior walls
- Condensation dripping from vent covers in summer
- Stained or soft drywall below a window
For small hard-surface spots, scrub with detergent and water, dry the area completely, and wear gloves, eye protection and an N-95 respirator. Replace caulk that stays stained rather than sealing over it, and bag porous items such as old bath mats that have grown mold.
Seasonal notes
Mildew usually spreads fastest from late spring to early fall, when Gulf humidity peaks, and after heavy storms. EPA recommends keeping humidity below 60 percent, ideally 30 to 50 percent, keeping AC drip pans clean and drain lines open, and drying any wet material within 24 to 48 hours. If a larger cleanup leads to rebuilding, the City of Webster Building Division handles permits and inspections. Webster has adopted the International Property Maintenance Code, and renters can report violations to the city's Code Enforcement through the Building Division. On professional projects, Texas requires a mold assessment consultant who holds a TDLR license and a separate remediation company.
