Baytown homes sit next to Galveston Bay and Cedar Bayou, so humid air reaches every cold surface in the AC system and condensation that has nowhere to drain feeds growth. Removing it involves two companies in Texas: a mold assessment consultant who scopes the coil, pan and ducts, and a separate remediation company that does the cleaning and replacement. Call the number on this page to be connected with a local mold remediation company in Baytown.
What happens when you call
The line routes you to an independent mold remediation company serving Baytown. Expect to be asked where you see growth (registers, ceiling, the unit closet, the attic), how long the smell has been there, whether the drain line has backed up, and whether the house took water in a storm. If no one has assessed the system yet, the company should explain that Texas requires a mold assessment consultant from another company to inspect first and write the protocol. That protocol lists the parts to clean or remove and the clearance criteria. The remediator then writes its own work plan and schedules the job, and you receive TDLR's Consumer Mold Information Sheet before work begins.
What moves the price
National ranges (HomeGuide, 2026) put mold work on an HVAC system or ductwork at $2,000 to $10,000. A Baytown job lands within or outside that range depending on:
- How many duct runs show growth and whether they are flex or sheet metal
- Attic access and heat, which slow the work
- Whether the air handler cabinet, blower and coil need cleaning
- Repairs an HVAC contractor makes to the drain, insulation or equipment
- The assessor's own fee for the protocol and clearance visit
Baytown conditions behind AC mold
Baytown, about 29 miles east of downtown Houston, is mostly in Harris County with a portion in Chambers County. Water borders it on three sides, from Galveston Bay to Cedar Bayou, with Goose Creek and the Houston Ship Channel close by. Hurricanes Carla, Alicia, Ike and Harvey are counted as the four storms that hurt the city most, and groundwater pumping left low areas such as the Brownwood subdivision prone to flooding. Ducts and returns that ever took water deserve a look, but the everyday driver is simpler: a system running nearly year-round in salty, humid air, with sweating ducts and a pan that never dries.
Checklist before work starts
- Shut the system off if you suspect contamination, as EPA advises
- Clear a path to the attic hatch and the unit closet
- Read the protocol and the remediator's work plan; they should match
- Look up both companies on TDLR's license search
- If ceiling drywall will be replaced, ask the City of Baytown Building Services Division whether the repair needs a permit
