Mold & Mildew Cleanup in Baytown, TX

What happens when you call

You will be connected with an independent local company that handles mold work in the Baytown area. Expect a few questions: where the mildew is, roughly how large an area, whether there has been a leak, a storm or flooding, and whether the growth comes back after cleaning. If the job is small and on hard surfaces, you may simply get advice on cleaning it yourself and controlling humidity. For larger or hidden growth, Texas law sets the sequence. A mold assessment consultant who holds a TDLR license inspects and writes a protocol, and a different company that holds a TDLR mold remediation contractor license does the cleanup. The same company cannot do both on one project.

What drives the cost

• Size and material. Wiping hard surfaces costs far less than cutting out drywall or pulling carpet.
• Where it is. A bathroom is simpler than a closet that backs onto an exterior wall or a ceiling below the attic.
• The moisture source. A plumber, roofer or HVAC technician may be needed before cleanup starts.
• Two companies. Professional projects usually mean paying an assessor and a remediator.

Angi's Houston cost data reports mold removal averaging $2,016, with most jobs between $863 and $3,329. National ranges (HomeGuide, 2026) put bathroom mold work at $500 to $2,000.

Why Baytown homes stay damp

Baytown, about 29 miles from downtown Houston and mostly in Harris County with part in Chambers County, is bordered by water on three sides: Galveston Bay to the south and west and Cedar Bayou to the east, with Goose Creek and the Houston Ship Channel nearby. Flat ground and the bay make flooding a recurring problem, and subsidence hit low-lying areas such as the Brownwood subdivision. Carla, Alicia, Ike and Harvey are named as the most damaging storms in the city's history. Humid bay air and a long cooling season keep moisture high indoors even between storms, so window frames, exterior closet walls and bathrooms tend to show mildew first.

If drywall or framing comes out, the City of Baytown Building Services Division issues permits for the rebuild, and properties in flood hazard areas may need floodplain review.

Before the company arrives

• Do not scrub or bleach the area the day of the visit, so the extent is visible.
• Note when you first saw the growth and any recent leaks or storms.
• Clear a path to the affected rooms, the attic hatch and the AC closet.
• Write down the indoor humidity if you own a hygrometer.
