In Dayton, a mold inspection is a hands-on assessment by a TDLR license holder: moisture readings, a look at the AC, attic and wet areas, and a written report. If the mold needs professional removal, the inspector writes the plan and a different company does the work. Call the number on this page to be connected with a local mold inspector in Dayton.

When to call for an inspection
- A musty smell you cannot trace, especially in closets or near the AC return
- Water got into the house from a storm, a burst line or an overflowing pan
- Growth keeps coming back after you clean it
- Baseboards or drywall feel damp or crumble when pressed
- You are buying a house and want to know what old stains mean
Local conditions in Dayton
Dayton is a Liberty County city on US 90, about 38 miles from Houston, founded as West Liberty roughly three miles west of the Trinity River. It is a Union Pacific and BNSF rail junction with a BNSF yard just south of town. During Harvey, Lake Livingston releases into the Trinity matched the 1994 record, and more than 7,000 homes across Liberty County were affected. If your house took water in Harvey or a later storm, ask the inspector to focus on the lower walls and flooring. More often, mold here starts with the same things as everywhere around Houston: long humid summers, AC ducts and drain pans that sweat, and leaks around roofs, windows and plumbing.

What affects the price
Angi's Houston cost data reports an average of $453 for inspection and testing, with most between $355 and $563. National ranges from HomeGuide (2026) run $300 to $650 for an average home. The size of the house, attic access and the number of lab samples drive the final bill. Because Texas separates assessment from remediation on the same project, any removal is priced by another company, and the assessor's clearance visit comes after.
What happens when you call
You are connected with an independent local company that does mold assessment. Look up its TDLR license before the appointment, and expect to receive TDLR's Consumer Mold Information Sheet before work begins. The inspector checks the house, explains the findings and gives you a report. If remediation follows, you get a protocol at least one calendar day before work starts. Repairs that need permits go through the City of Dayton Building Division under Planning and Development Services; plan review for new construction can take up to 10 days, and most permits require inspections.
