Position and Secure Carpet Runner

What happens in this clip

Place a pre-cut carpet runner on a stair tread, ensuring it is centered and straight over the padding and tack strips. Press the carpet firmly onto the tack strip at the back of the tread. Using a stair tool (also known as a carpet tucker or bolster tool), firmly push the carpet into the crease where the stair tread meets the riser, creating a clean, tight corner. Then, pull the carpet taut over the nosing and staple it to the underside of the nosing. Repeat this process for each stair, working from top to bottom or bottom to top.

Goal: Attach the main body of the carpet runner to each stair tread.

About the full video

This project provides a step-by-step guide to installing carpet runners on a staircase. It covers preparing the stairs by removing old materials, installing new tack strips and padding, precisely positioning and securing the carpet runners using a staple gun and stair tools, and finally trimming and finishing the edges for a professional look.

Step 5 of 5: Trim Edges and Secure

Once the treads are in place, inspect the edges. If there is any slight overhang or unevenness, carefully trim it with a sharp utility knife. For extra security, especially on spiral stairs where edges can be more prone to lifting, consider using small, discrete carpet tacks or staples along the very edge of the tread, driven into the metal. Ensure these fasteners are not a tripping hazard.
