Steps for Restoring a Deck

  1. Making Repairs. Use a pry bar to pull damaged boards. Remove fasteners and lift the board straight up to avoid damaging adjacent boards.
  2. Cleaning the Surface. Trim the replacement boards with a circular saw. Using adjacent boards as a cutting guide is faster and more accurate than measuring.
  3. Applying the Stain. Mesh filters (about $1 each) catch any particles that could wind up clogging the nozzle on the washer.
  4. Redoing a Railing. Because the original railing on their deck was in such bad shape, the Johnsons decided to replace it with a maintenance-free railing system.
