What changes the price
- How big the affected area is

- Rebuilding afterward (drywall, paint, flooring) is often separate
- Assessment and clearance testing by the licensed consultant

Ask each company for a written scope based on the assessor's protocol, so you compare the same work. See Texas mold rules and water damage costs.
Common questions
How much does mold removal cost?
National 2026 guides put most professional mold remediation jobs between about $1,200 and $3,750, with an average around $2,300 to $2,370. Local quotes vary.
Why are small jobs expensive per square foot?
Many companies have a minimum charge for setup, containment and disposal, so small areas often cost more per square foot.
