Certified Mold Remediation in Plano

Mold remediation in Plano typically ranges from $1,500 to $5,000 for a contained bathroom or closet project. Larger jobs involving attic sheathing, multiple rooms, or HVAC ductwork contamination generally run between $5,000 and $15,000. Texas law requires separate licensed assessors and contractors, so the total cost includes both the assessment protocol and the remediation work. Verify that both the mold assessment consultant and the remediation contractor hold current licenses through your state contractor licensing board — Texas prohibits the same firm from performing both functions on the same project. Insist on a written scope of work referencing the IICRC S520 standard and require post-remediation clearance testing by an independent licensed assessor, which is also required under Texas regulations. Plano homeowners should correct the underlying moisture source — whether a slab leak, roof penetration, or HVAC condensate line — before or during remediation, or new mold growth will reoccur.

Yes. Texas DSHS HB329 requires all mold remediation contractors operating in Plano and throughout Texas to hold a current state-issued license. The law also prohibits the same firm from performing both the assessment and the remediation on the same project. Always verify a contractor's license number on the Texas DSHS website before signing any contract. This separation requirement protects Plano homeowners by ensuring an independent professional designs the remediation protocol and a different licensed contractor executes it. After remediation is complete, a separate licensed mold assessment consultant must conduct clearance testing to confirm the work meets the original protocol — this post-remediation report is the document your insurance adjuster and future home buyers will require. If a contractor offers to handle assessment, remediation, and clearance under one firm, that is a violation of Texas law; do not proceed and report the contractor to the appropriate state licensing authority.

Under Texas law, a licensed mold assessment consultant must produce a written remediation protocol before work begins, which typically takes 24 to 48 hours after the initial inspection. Once the protocol is issued, a licensed remediation contractor in the Plano area can generally mobilize within one to two business days. For active water intrusion events, emergency moisture control can begin immediately while the formal assessment is completed. Acting quickly is critical — mold begins colonizing wet building materials within 24 to 48 hours of water intrusion, and Plano's hot, humid summers accelerate that growth cycle. Emergency extraction and drying performed before the formal protocol is finalized limits the spread of contamination and reduces the ultimate scope of the remediation project. Call a licensed contractor as soon as you discover water intrusion or visible mold growth; do not wait for the problem to worsen before beginning the assessment process.
