Replace Damaged Stair Treads or Risers

What happens in this clip

Inspect the exposed stair treads and risers. If they are in poor condition (e.g., warped, splintered, or heavily damaged by old glue), they may need to be replaced. For replacement, use a hammer and a crowbar to carefully pry up the old treads. The video creator used new stair treads from Home Depot. Measure each existing tread individually using a tape measure, as stair dimensions can vary slightly. Use a circular saw to cut the new treads to the precise measured lengths. Test fit each new tread before securing. Apply liquid nails to the stringers (the support beams) and then use 2 1/2-inch nails with a brad nailer to firmly attach the new treads. If risers are also damaged, consider using retro risers (available at hardware stores like Lowe's) which are two-sided (wood grain and paintable white) and can be cut to fit, then glued and nailed in place.

Goal: Install new stair treads and/or risers if existing ones are damaged beyond repair.

About the full video

This project details the step-by-step process of transforming carpeted stairs into stained wooden stairs. It covers the removal of old carpet, replacement of damaged treads, preparation of the wood surfaces, application of an oil-based stain and a protective top coat, and finishing with painted risers and caulking for a clean, modern look.

Step 2 of 6: Inspect and Repair Staircase Structure

Examine all wooden components for signs of decay, insect damage, or structural compromise. Pay close attention to the areas where treads meet stringers and risers. Any loose connections should be re-secured with screws or construction adhesive. Damaged sections may require patching or replacement with new wood. Ensure the sub-treads are level and sound. If the sub-treads are in poor condition, they may need to be replaced or covered with a plywood layer.
