How We Repair Your Subfloor

1. Remove Damaged Material

Open the agreed repair area and remove damaged flooring or subfloor material to expose the supporting framing.

2. Repair Framing & Add Blocking

Complete the agreed joist repairs and install blocking beneath unsupported subfloor edges and panel joints. Additional damage is reviewed before extra work proceeds.

3. Install the New Subfloor

Fit replacement plywood, OSB or other specified subfloor material to the repair area and fasten it to the supporting framing.

4. Prepare for Flooring

Check the repaired surface and panel connections, clean the work area and identify any additional preparation needed for your planned flooring.
