Should Mold Remediation Be Done First?

Repairing Your Bathroom Floor

To begin repairing your bathroom floor. Here are the steps to take:

  1. Turn off the water: Close the main water valve to prevent any more water from coming into the room as you work.
  2. Prep the area: Remove anything sitting on top of the damaged floors so you have an open area in which to work. Use a pry bar to remove any protruding nails and the floor’s baseboards.
  3. Inspect the area: Look at the floor joists and figure out which ones are on either side of the water-damaged area. Draw a clear, rectangular area of damage.
  4. Remove damages: Use a cat’s paw and hammer to pull out fasteners or a drill to remove screws. Cut along the lines that form the rectangle and lift out this area.
  5. Give time for the area to dry: If the joists are wet, ventilate the area and give them a few days to dry thoroughly.
  6. Reinforce the joists: Nail new wood over the rotted areas, making sure each end is on top of good wood.
  7. Cover the gap: Measure the specific dimensions of your rectangular area, and cut plywood or oriented strand board (OSB) to cover it. Set this new material in place with 2-inch wood screws, leaving a 1/8-inch gap between the new and existing flooring. Use floor compound to fill that gap, level out unevenness, and sand the area if necessary.
