Stair Tread Replacement

Gently wedge your pry bar under the edge of an old tread. Tap the pry bar with your hammer to begin lifting the wood. Work your way around the tread, repeating this process to loosen it from the screws. For any especially stubborn fasteners, a reciprocating saw can be a great help. Safety first: be extremely careful to cut only the old screws or nails, not the underlying stair stringers (the support beams your treads rest on). Damaging the stringers can create a much bigger project.

Take a moment to inspect the stair stringers. Remove any leftover hardware, splinters, or old adhesive residue. A stiff brush and a scraper are perfect for this job. The goal is a clean, smooth, and level surface. This simple prep work is key to ensuring your new treads sit flush and are properly supported for long-lasting safety.

Carefully measure the width of the stair opening for each tread you're replacing—don't assume they're all identical! Mark these measurements clearly on your new treated lumber. Using a circular saw or a handsaw, make your cuts. Strive for perfectly straight, square cuts, as this will ensure your new treads fit beautifully without any unsightly gaps.

Position a new tread onto the clean stringers. Make sure it sits flush against the front edge and fits snugly side-to-side. To prevent the wood from splitting and ensure a strong hold, always pre-drill pilot holes through the tread and into the stringer below. Then, drive high-quality, exterior-grade screws through your pilot holes to fasten the tread securely. For maximum stability, use a minimum of two screws for each point where the tread meets a stringer.

With your new treads firmly in place, consider this final step to protect your hard work. Choose a quality wood sealant or stain formulated for outdoor use. Using a brush or roller, apply an even coat, always following the manufacturer's specific instructions for application and drying times. This will not only enhance the look of the wood but also provide crucial protection against moisture and wear, ensuring your stairs look great for years to come.
