Most mildew in Pasadena homes is surface growth on grout, caulk, windows or closet walls, and a homeowner can usually clean small areas while lowering indoor humidity. Mildew that soaks into drywall or carpet, covers a large area, or keeps returning signals a hidden moisture problem that calls for a professional. Call the number on this page to be connected with a local mold remediation company in Pasadena.

What makes Pasadena homes damp
Pasadena is a large, mostly working-class city of about 152,000 people, roughly 17 miles from downtown Houston. The Houston Ship Channel forms its northern border, Vince's Bayou runs through it, and its southeastern corner fronts Galveston Bay near Armand Bayou. The 1900 Galveston hurricane heavily damaged Pasadena, and the region's heavy rains still test roofs and drainage. Neighborhoods range from Red Bluff Terrace and Golden Acres to Parkview Manor and Burke Meadows. Inside the house, humid air, a long cooling season, bath fans that underperform and AC equipment that sweats are what keep mildew coming back.
DIY cleanup vs calling a company
| Situation | Homeowner cleanup | Company |
|---|---|---|
| Dark grout lines or a moldy shower curtain | Yes: scrub, rinse, dry, run the fan longer | No |
| Small patch on a painted wall or ceiling | Yes, if the paint is intact | If it returns quickly |
| Spots around several AC vents | Clean the covers | Have the AC and ducts checked |
| Growth on drywall that feels soft | No | Yes, material likely needs removal |
| Growth after a roof leak or flood | No | Yes |

Signs to watch
- A musty smell when the AC first kicks on
- Dark spots spreading from a corner of the bathroom ceiling
- Peeling paint near tubs and showers
- Mildew on clothing in a closet you rarely open
- Condensation dripping from a window frame on humid mornings
Small surface spots are a cleaning job. Use detergent and water on hard surfaces, dry them fully, and wear gloves, eye protection and an N-95 respirator. Throw out porous items that have grown mold, such as old bath mats or ceiling tiles, and replace caulk that stays stained rather than sealing over it. Texas lets homeowners clean their own home at any size, but anyone you hire for mold work needs a TDLR license, and on a larger job the assessor and the remediation company must be separate. Angi's Houston cost data reports mold removal averaging $2,016.
Timing and seasons
Expect mildew to surge between late spring and early fall, when humidity is highest. EPA advises keeping indoor humidity below 60 percent, ideally 30 to 50 percent, and drying anything wet within 24 to 48 hours. If cleanup leads to new drywall, residential building permits are filed with the City of Pasadena Permit Department. Renters with leaks a landlord hasn't fixed can contact Pasadena Code Enforcement, which enforces the city's housing and sanitation ordinances.
