Drywall is the single biggest decision in a water loss. Cut too much and you've turned a $400 dry-out into a $6,000 reconstruction. Cut too little and mold colonizes the cavity within 72 hours. Here's the IICRC-grade decision tree we use on every Oklahoma job.
Step 1: Identify the Water Category
- Category 1 (clean): supply line, ice maker, rainwater. Drywall often dryable.
- Category 2 (gray): dishwasher, washing machine, sump pump fail. Drywall must be removed if porous (most painted drywall).
- Category 3 (black): sewage, ground flood, toilet overflow past trap. Always cut out, no exceptions.
Step 2: Time Since the Loss
Even Category 1 water becomes Category 2 after 48 hours and Category 3 after 5 days. This "category creep" is why fast response matters more than equipment quality.
Step 3: Insulation Behind the Wall
Fiberglass batt insulation that gets wet doesn't dry, it slumps. The R-value collapses and the cavity becomes a permanent moisture reservoir. Closed-cell spray foam is the opposite: it sheds water and the wall behind it dries faster than open-frame.
The Flood Cut
Standard practice is to cut drywall 12 to 24 inches above the water line. The cut runs in a straight horizontal line so reconstruction is efficient. We always document moisture readings before and after the cut so your adjuster has defensible data.
OKC Pricing (2026)
- Dry-in-place (Cat 1, less than 24 hr): $400 to $900 per room
- Flood cut + replace (single wall): $1,200 to $2,800
- Full room reconstruction: $3,500 to $7,500
Mold Risk Timeline
Drywall paper is cellulose, which is mold's favorite food. Visible growth typically starts at 48 to 72 hours of sustained moisture. See ourmold-after-water guidefor the full timeline.
