Dry rot repair by affected part

Subfloor & Floor Rot Repair

A soft or spongy floor near a toilet, shower, tub, sink cabinet, laundry area or water heater can point to damaged finish flooring or subfloor below.

What this can include

  • Plywood, OSB or plank subfloor and underlayment
  • Flooring around toilets, showers, tubs and kitchen sink cabinets
  • Laundry and water-heater leak areas, with source work handled by the appropriate trade

Scope boundary

What a specialist may need to handle

Photos help identify the affected parts, but hidden damage and moisture sources require property-specific review. Specialty and permit work must be confirmed before repair.

Questions about soft floor & subfloor

Is a soft bathroom floor always subfloor rot?

No. The finish, underlayment and subfloor can fail in different ways. An assessment separates the visible symptom from the material that actually needs repair.

Can the floor be closed before a leak is fixed?

The water source and drying condition should be addressed by the responsible trade before the wood repair is enclosed.
