How to Install Carpet Treads on Extra-Wide Stairs

Using a tape measure, record the exact width of each stair tread from wall to wall. Also, measure the depth of the tread from the nose of the tread to the riser. Repeat this for every stair you intend to cover.

Vacuum or brush away any loose dirt, dust, or debris from each stair tread. Inspect the surface for any loose carpet fibers, staples, or nails. If present, carefully remove them. For wooden stairs, ensure the surface is smooth and free of splinters or significant imperfections. Wipe down each tread with a damp cloth to remove any remaining dust.

Lay out your carpet treads on a flat surface. Using your initial measurements, carefully mark the cutting lines on the back of each carpet tread. Employ a sharp utility knife or heavy-duty scissors to cut along these lines. Ensure the cuts are straight and precise to match the stair dimensions.

Starting with the bottom-most stair, peel back the adhesive backing on the carpet tread. Align the tread precisely with the edges of the stair tread, ensuring it is centered and flush with the riser. Once positioned, press down firmly across the entire surface of the tread to ensure a strong bond.

Move to the next stair tread. Align the new carpet tread with the riser and the side walls, ensuring it meets the previously installed tread seamlessly if applicable. Press down firmly across the entire surface to secure the tread. Repeat this process for all remaining stairs.

Walk up and down the stairs, pressing on each carpet tread to ensure it is firmly attached. Check for any lifting edges or loose areas. If any tread feels loose, apply additional pressure or use a recommended adhesive if necessary. Wipe down the installed treads with a clean, dry cloth to remove any fingerprints or smudges.
