Carpet runners can transform a steep, slick, quirky, or outdated set of stairs from a creaky tripping hazard into a sound-absorbing, traction-covered dream. Stair runners are a good option if you have the type of tread that provides little traction on steep stairs. With the number of carpet runner fabrics and designs available, you can find a stair runner in the right shade and pattern to fit your decor and add practical value. This project can save some cash on carpet installation costs, so take a look at how to install carpet runners yourself.
Prepping for Carpet Runner Installation
Carpet installation preparation includes careful measuring. For stairs, you will need to measure the height of the riser (vertical side of the stair) and the depth of the tread (the top surface of the stair). Multiply the height of the riser by the number of risers on the staircase. Then multiply the depth of the tread by the number of treads on the staircase. Add the two numbers together and add six to eight inches to make up for any waste. The final number is the carpet runner length you will need.
Carpet runners come in 27- and 32-inch widths. Measure the width of your staircase to decide which width will work best for your stairs, making sure to leave two to three inches of space between the edge of the runners and the baluster and skirtboard.
Choose Your Method
You can install carpet runners on stairs using one of two methods—Hollywood (sometimes called upholstered) and waterfall. The Hollywood method follows the contour of the stairs, attaching under the nose (the lip) of the stairs for a tighter fit. The waterfall method involves attaching the carpet to the edge of the tread and dropping straight down to the bottom of the riser without following the contour of the stair. The Hollywood method is more sleek and crisp, but the waterfall method offers easier installation.
Subtract the width of the stair runner from the width of the staircase (measurement from the baluster to the skirtboard). Divide this number by two to determine how much space you need to leave between the skirtboard and baluster on each side of the runner.
Use a pencil to mark this distance from the baluster and from the skirtboard. These lines will act as layout marks as you place the runner.
Cut the Tack Strip
Use sheet-metal snips to cut the tack strips two to three inches shorter than the width of the runner. You need one tack strip for each tread, so cut as many as needed for the size of the staircase.
Nail the Tack Strips in Place
At the bottom of the first riser, place a piece of scrap tack strip between the riser and the first tack strip. The scrap piece will provide uniform spacing for the tack strip placement on each tread. Center the tack strip (not the scrap) between your layout marks and make sure the tacks are angled toward the riser. Nail the tack strip in place using either a hammer or a nail gun. Install at least one nail within two inches of both ends of the tack strip.
Cut the Carpet Pad the Same Length as the Tack Strip
Use a utility knife to cut the carpet pad to the same length as the tack strips—and three inches deeper than the tread if you are wrapping the carpet pad over the nose of the stairs. If you are not wrapping the carpet pad around the nose, cut the pad slightly shallower than the depth of the tread minus the depth of the tack strip.
You can do it either way (wrapping around the nose or not), though it is more common to wrap the carpet pad over the nose when doing the Hollywood method. It is less important with the waterfall method because this method does not require the same level of precision.
Cut one piece of carpet pad per stair.
Position and Fasten the Carpet Pad on All of the Stairs
Place the pad against the tack strip’s front edge. Starting from the center of the tread, use a staple gun and 9/16th-inch staples to attach the carpet pad to the tread on the edge that is against the tack strip. Staple approximately every three inches. Pull the carpet pad tight under the nose of the tread. Staple every three inches under the nosing.
Check the Edge of the Runner With a Framing Square
Use a framing square to check the edges of the carpet runner square. If the edges aren’t square, it makes it nearly impossible to install the runner straight. For runner edges that are not square, use the framing square and a pencil to mark the back of the runner and use a carpet knife to trim the corner to make the carpet edge square.
Glue the Edges of the Carpet Runner
Use latex carpet glue to touch up the carpet runner’s edges to avoid fraying. Let the glue dry to the touch before moving to the next step.
Unroll the Carpet Runner Over the Bottom Three or Four Stairs
Start at the bottom stair, and unroll the carpet runner over the bottom three or four stairs. Use the layout guides to line up the carpet runner on the first riser. As long as the carpet runner edge is square and you position it according to the layout guides, it should go straight up the stairs fairly easily.
Staple the Runner to the Bottom of the First Riser
Press the carpet runner into the bottom of the first riser. Starting at the center, staple the carpet runner every three inches. You will get the best results by pressing the stapler through the pile, which can be shallow or deep, depending on the type of carpet. Staple through the backing every three inches to secure the carpet fully.
Staple the Runner Under the Nosing (Hollywood/Upholstered Style Only)
Pull the carpet tight to the bottom of the nosing and staple it every three inches. If you are using the waterfall style, you can skip this step.
Check the Runner Placement and Pull the Carpet Over the Nosing
The carpet should still be lined up with the layout guides. Check the alignment as you pull the carpet over the nosing. Pull the carpet tight. Then push the carpet runner onto the tack strip, which will hold the carpet in place.
Fix Any Buckling
The carpet runner may buckle at this point. If it does, remove the carpet from the tack strip and start the particular stair over again. Buckling at any point can throw off the runner’s alignment and lead to the carpet coming loose over time.
Press the Seam Between the Tread and Riser With a Carpet Tucker
Use the carpet tucker or a knee kicker to tuck the carpet between the seam of the tread and the riser. Whether you are doing the Hollywood or waterfall method, you want a tight seam with the carpet firmly taut in the tack strip and tucked into the seam.
Staple From the Center Toward the Edges
Staple the carpet runner as close to the seam of the tread and riser as possible. Start at the center and staple every three inches moving toward the edges.
Repeat Steps 10 Through 16 Until You’ve Covered All of the Stairs
From here, you will repeat the process with every stair. Remember to check alignment using the layout guides and be sure the carpet stays taut and firmly attached to the tack strip on each tread.
Leave Approximately One Inch at the Top of the Stairs and Tuck
At the top, leave at least one inch of extra carpet to tuck under the raw edge. Staple this edge to the top tread.
DIY vs. Hiring a Pro
Professional carpet installers may charge anywhere from $16 to $30 per hour. Installing a carpet runner on stairs is not a complicated project. However, it can take anywhere from five to six hours, depending on the length of the staircase. This is a project that most DIYers with a little experience can handle, but it does take time and precision, so be ready to spend the better part of a day. If you do not have the time or tools necessary to make this project doable in one day, it might be worth getting a quote from a local carpet installer.
Frequently Asked Questions
Stair runners are often easier to install than a standard carpet because the latter must be cut to fit the stairs with extra steps taken to prevent fraying at the edges. Stair runners offer extra decorative options, padding, and traction to reduce the risk of falls. They can also offer a nice way to transition from one flooring type, like cement or epoxy floors to softer carpeting on an upper story of the home.
A stair runner can be cheaper than a carpet and will definitely save money over the cost of refinishing hardwood floors and stairs. The price depends, however, on the fabric and quality of the runner. A wool stair runner can be more expensive than an inexpensive polyester carpet and vice versa. Keep an eye on your budget, knowing that the higher quality the carpet and the carpet pad, the better the carpet will wear over time.
If the stairs are already covered in carpet, you will need to remove the old carpet and possibly the carpet pad. Any damage to the stairs like cracks, loose boards, or creaky treads may also need to be repaired. You may also want to sand and refinish or paint wood stairs before installing a carpet runner.
