Screws on deck

Did you know the average life expectancy of a pressure-treated deck can be up to 20 years? In order to maximize the lifespan of your deck, you’ll first need the proper treated wood. Download our Treated Lumber Standards Chart to educate yourself.

Second, you’ll want to keep up on regular deck maintenance each season because we all know Mother Nature is a powerful force! Debris, like leaves, often get stuck in between boards and, over time, can cause rot and decay. As soon as rotting is detected, you must replace those boards as they can compromise the structural integrity of your deck.

We want you to get the most out of your deck for as many years as possible. Let’s nail it together and get started on replacing those rotted deck boards.

Here’s what you’ll need:
  • Materials:
    • Deck board
    • Ceramic-coated deck screws
    • 2 ½” for 5/4” decking
    • 3” for 2” decking
  • Tools:
    • Tape measure
    • Crowbar
    • Drill
    • Quick square
    • Broom
    • Circular saw
Lets get started:

1. Remove old board

  • Before removing the old board, use a tape measure to determine how long the board is. Use a screwdriver to remove the old screws.  
  • After removing all screws from the board, use the crowbar to pull up and remove the board.
  • Sweep away any debris from the joist (understructure).

2. Install new board

  • Mark the new board’s measurement with a quick square using the old board’s length. This will indicate your cutting line.  
  • Position the new board on sawhorses. Make your cut with a circular saw.  

3. Attach new board

  • Set boards in place before attaching to the joist. As a guide, use the screws on the adjoining boards to mark a line on your new boards for screw placement. This will ensure a solid connection to the joists.
  • Screw the boards into place by starting at the end and working your way down. After you’ve attached the new boards, you are done with the repair!

This simple repair is a quick and easy project that will extend the life of your wood deck. Don’t forget to wear proper safety gear such as eye and ear protection.

Since May is Deck Safety Month, now is a good reminder to take the time to check the entirety of your deck and not just the boards. Make sure to check your ledgers, railings and footers, and check for any loose screws. A safe deck is a smart deck!
