Replacing a Step


Because they get more traffic, steps wear out faster than other portions of your deck. To ensure everyone’s safety, immediately replace any steps that show signs of deterioration or serious damage.

For replacement steps, use treated deck lumber, cedar or redwood that closely matches the existing steps. Seal the new steps thoroughly, paying special attention to the cut ends.




Step 1: Remove all damaged steps

Remove damaged steps

Remove a damaged step by first cutting it in half. You should then be able to use a pry bar to pull the halves away from the nails. If your steps are fastened with screws, just back out the screws, then remove the step or steps. Measure the width of the stair treads, and mark the tread outline on the stringers using a pencil. Cut lumber to needed length.


Step 2: Position front 2x6 on tread cleat

Position front 2x6 on tread cleat Position the front 2x6 on the tread cleat or notched stringer so that the front edge is flush with the tread outline on the stringers.

Step 3: Position rear 2x6 on tread cleat

Position rear 2x6 on tread cleat

Position the rear 2x6 on the cleat or notched stringer, allowing a small space between the two treads and between the rear tread and the riser. Use a 16d (3 ½-inch) nail as a spacing guide. Drill 1/8-inch pilot holes and fasten the 2x6s to the cleats or stringers with nails or screws.
