Step 1: Assess the Damage

The first step in repairing water-damaged wood is to assess the extent of the damage. Depending on the severity of the damage, you may be able to repair it yourself or you may need to call in a professional.

Signs of Water Damage to Wood:

  • Discoloration

Step 2: Remove the Damaged Wood

Once you've assessed the damage, you'll need to remove any damaged wood. Use a saw or other cutting tool to cut away the damaged wood, making sure to remove all of the affected areas.

Step 3: Dry the Area

After removing the damaged wood, you'll need to dry the area thoroughly. Use a fan or dehumidifier to dry the area, and make sure there is good ventilation to prevent mold from growing.

Step 4: Sand the Area

After the area is dry, use a sander to smooth out any rough edges or uneven surfaces. Sand the area until it is smooth and level.

Step 5: Apply a Wood Filler

Fill any gaps or holes with a wood filler. Apply the filler with a putty knife, making sure to fill the entire area. Allow the filler to dry completely before sanding it down to a smooth finish.

After the filler has dried, use a sander to smooth out any rough areas and make the surface level.
