Budget
Patch small area (under 20 sq ft) of water-damaged OSB subfloor, single layer, bathroom or kitchen. Typical scope: cut out rotted section, sister one or two joists if soft but not structurally compromised, screw down new OSB panel.
Mid-Range
Replace 50-80 sq ft section of subfloor with some joist sistering. Includes new 3/4-inch OSB sheathing, construction adhesive, ring-shank screws, and blocking where needed. Typical cause: prolonged leak from toilet wax ring, slow pipe drip, or failed shower pan.
Premium
Large-scale subfloor replacement covering 200+ sq ft, extensive joist repair or sister work, self-leveling compound to bring surface flat, and removal of existing floor covering (tile, hardwood, or laminate). May include access panel installation and mold remediation if water damage was prolonged.
Material Options
Material prices below are national averages; availability in Richmond may shift costs slightly.
| Material | Cost/Unit | Best For |
|---|---|---|
| OSB Subfloor (3/4" T&G) | $25-$35 per sheet | Dry areas like bedrooms and living rooms where moisture is not a concern; budget repairs where the leak source is fully resolvedLowest cost per sheet, widely stocked at big-box stores, tongue-and-groove edges create tight seams without blocking |
| Plywood Subfloor (3/4" T&G, Sanded) | $45-$65 per sheet | Kitchens, bathrooms, and anywhere the floor covering will be hardwood or engineered wood that requires a smooth, stable baseMore moisture-resistant than OSB, holds screws better over time, preferred by most flooring installers as a base for hardwood |
| Cement Board (HardieBacker / Durock) | $15-$25 per sheet (1/4" or 1/2") | Tile installations in bathrooms, showers, laundry rooms, and entryways where moisture exposure is ongoingCompletely unaffected by water, provides ideal bonding surface for tile, prevents future rot under wet-area tile installations |
| SurePly / Underlayment-Grade Plywood (1/4") | $20-$30 per sheet | Leveling and smoothing a repaired subfloor before installing vinyl plank, sheet vinyl, or laminate; never use as a primary structural replacementSmooth surface fills minor subfloor imperfections, reduces telegraphing to vinyl or LVP above, fast to install |
