How to Repair Termite Damage to Floors
- 1). Remove top floorboards above any damaged subfloor pieces. If possible, attempt the repairs by crawling under your house or fix the damage from a basement order to preserve your interior floors.
- 2). Disconnect any utilities or wires that may be near the damaged wood.
- 3). Place a 2-by-4 floor joist as close to the termite-damaged floor joist as possible. Secure the new 2-by-4 by nailing it to the crossbeam base of the floor. This provides the structural support the damaged beam had been shouldering.
