Over time, the wooden treads on your home staircase can be worn down by the endless number of feet traveling back and forth across them. The treads can split and crack, weakening the step and creating a hazard. In addition, damaged steps can produce a lot of noise in your home. Since (in most cases) the treads are just nailed down, replacing one or more of them is relatively simple.

What You'll Need

  • Crowbar

  • Hammer

  • Nails

  • Block of Wood

  • Screwdrivers

  • Pair of Pliers

  • Drill

  • 3/16 Twist Bit

  • Circular Saw (optional)

  • Measuring Tape

  • Replacement Tread

  • Sandpaper

  • Finish

  • Protective Gloves and Eye Wear

Step 1. Put on protective gloves and eyewear. Use a small crowbar to pry up any molding or trim connected to the damage tread you want to replace. If any nails are left behind when the molding is removed, use a hammer to pull these out as well.

Step 2. If there are any balusters on the stair tread you're removing, position a block of wood against the baluster and strike it with a hammer to push it outward and away from the tread. Remove any nails that are still in the tread after the balusters have been removed.

Step 3. Use the crowbar to pry up the tread you want to replace. To do this, position the bar between the stringer and the stair tread, using the hammer to tap on the end of the bar to get it in between. Then push down on the crowbar to pry up the tread. You may have to hammer the crowbar in and lift several times before you could completely free the tread. Once you have, lift it away by hand.

Step 4. Use the hammer or a pair of pliers to remove any nails remaining in the structure under the tread.

Step 5. Carefully measure the old tread and purchase a new tread that matches it in width and thickness. It's best to use the same type of wood as the tread you removed. If the tread you're replacing is a rounded edge, make sure that you purchase a replacement tread that matches this as well.

Step 6. Have the home improvement store cut the tread to the length you need based on your measurements. Alternatively, use a circular saw to cut it yourself.

Step 7. Use sandpaper to sand the tread until it is smooth. Drill small pilot holes at each end of the replacement tread, using the old tread for a template. Drilling holes will help you avoid splitting the wood when you're hammering in the nails.

Step 8. Position the tread and nail it into place. Reposition the balusters, molding and trim and nail them back into place as well. Apply a finish to the new tread so it will match the other treads. Allow the finish to dry.
