plano tx foundation slab crack caused hidden under-slab sewer line mold - how to get tdi mdr-1 certificate in 48 hours?

Question

selling our 1980s brick home in plano tx (collin county). the buyer's hydrostatic plumbing test revealed a slab sewer line break that saturated the foundation base and caused mold under the living room laminate flooring.

buyer is threatening to walk unless we provide a Texas Department of Insurance (TDI) Form MDR-1 Certificate of Remediation before closing next week.

how do we coordinate the plumbing repair, structural slab drying, and TDI MDR-1 certification in 48 to 72 hours in DFW?

Direct Answer:  You can secure an expedited TDI Form MDR-1 within 72 hours by following the Texas Occupations Code Chapter 1958 protocol: (1) hire a licensed Mold Assessment Consultant (MAC) to issue an immediate Mold Remediation Protocol, (2) have a licensed Mold Remediation Contractor (MRC) extract damaged flooring and sanitize slab cracks under negative air, and (3) have the MAC pull PRV air cassettes to execute the state MDR-1 certificate. 
 In Collin and Dallas Counties, expansive black clay soils shift, fracturing sub-slab drain pipes. Sewer water carries Category 3 blackwater pathogens that wick through concrete cracks. Under Texas Insurance Code § 1952.302, obtaining Form MDR-1 is the only legal mechanism to remove mold history stigmas on Texas property titles. 
 The 72-hour DFW rapid certification protocol: 
 
    Day 1 (Morning): Plumbing Epoxy Relining & Assessor Protocol:  Plumber lines pipe while MAC publishes statutory protocol. 
    Day 1 (Afternoon): Negative Air Containment:  MRC seals living room with 6-mil poly and extracts damp flooring. 
    Day 2: Concrete Sanitization & LGR Drying:  Treat slab fissures with EPA botanical biocide and run desiccant dehumidifiers. 
    Day 3: PRV Lab Testing & Form MDR-1 Delivery:  Assessor verifies Condition 1 clearance and executes state certificate.

As a DFW real estate broker: Buyers in Plano get terrified when they hear 'slab leak'. Handing them the TDI Form MDR-1 with the passing lab results turns a potential deal-killer into an immediate closing.

Title companies in Collin County will immediately clear the property title environmental exception once the signed MDR-1 is received.

Update:  Plumbers relined the pipe yesterday and the mold crew has the living room contained. Concrete slab moisture is already dropping rapidly.

Make sure they apply a concrete vapor mitigation barrier over that crack before the buyer installs new flooring so moisture never returns.

Final Update:  PRV testing passed with flying colors and the MAC signed the official TDI Form MDR-1 today! Buyer signed off on all repair contingencies!
