What Is the Average Cost of Black Mold Removal in Texas?

Black mold removal cost in Texas typically runs from a few hundred dollars for a small, contained bathroom or closet job up to $10,000–$30,000+ for a severe, whole-house infestation involving crawlspaces, attics, or extensive drywall replacement. Most moderate jobs — a few rooms or an HVAC system affected — fall in the $2,000–$6,000 range. Because Texas requires licensed professionals for most jobs, your total cost usually includes a separate assessment fee on top of the remediation work itself.

The exact price depends on the size of the affected area, whether mold has spread into wall cavities or ductwork, the underlying moisture source, and local labor rates in your part of the state. Here's how the numbers typically break down and what shapes them.

How much does black mold removal cost by job size?

Industry pricing generally falls into three tiers:

• Small, contained jobs (a bathroom ceiling, shower surround, or small closet): roughly $500–$1,500. These are often small enough to fall under Texas's minor-area exemption from licensing requirements, discussed below.
• Moderate jobs (multiple rooms, mold that has traveled through HVAC ducts, or moisture damage behind several walls): commonly $2,000–$6,000.
• Severe or whole-house infestations (long-term leaks, flood damage, crawlspace or attic contamination, structural rot): $10,000–$30,000 or more, especially when drywall, insulation, and flooring need to be torn out and replaced.

These are general industry ranges, not fixed quotes. Get an in-person inspection and written estimate before assuming your project fits neatly into one tier — a small visible patch can hide a much larger problem inside a wall.

Why does Texas mold removal cost more than a simple cleaning job?

A few Texas-specific factors push costs up compared to a basic DIY cleanup:

• Mandatory licensed assessment. Texas is one of the few states that licenses mold professionals under Texas Occupations Code Chapter 1958. For most non-exempt jobs, a separate licensed Mold Assessment Consultant must inspect the property and write a remediation protocol before a licensed Mold Remediation Contractor can begin work. This assessment is typically billed separately from the remediation itself, often adding several hundred dollars to the total. Details on license categories are on the
