How to Install a Stair Runner: Step-by-Step DIY Guide with Tools & Tips

Wool Fabulous Diamond Stair Runner with Cotton Pale Stone Border

The impulse to DIY will grip all of us at some stage. That desire to bypass the arduous search for a professional and give a practical hands-on approach a try.

We at The Natural Rug Company pride ourselves on providing the highest quality materials. Any stair runner has to be both hardwearing and eye-catching to work in a home. Why not have a look at the whole range that we have on offer?

I'm a firm believer that we are all more than capable of whatever we set our minds to, with that in mind - here is a guide to how you can install your own stair runner.

What tools will you need?

• Measuring tape

• Pencil or chalk

• Staple gun

• Double-sided carpet tape

• Utility knife

• Rubber mallet

• Knee kicker (optional but helpful)

• Straight edge (for cutting)

Step 1: Prepare the Stairs

1. Clean the Stairs: Ensure your stairs are clean and dry. Sweep away dust and debris so the adhesive and staples hold properly.

2. Ensure all paint and varnish has had time to cure: If you've given your stairs a new lick of paint or updated the wood varnish, follow the instructions on the tin and ensure that the applied layer has had as long as it needs to harden.

3. Mark the Centreline: Use a measuring tape to find the center of each stair tread and riser. Mark the centreline lightly with a pencil or chalk. This will help keep the runner straight.

Step 2: Install Carpet Underlay(if using)

1. Cut the Underlay: Cut a piece of carpet underlay slightly narrower than your runner (about 3cm less on each side).

   
   

2. Attach the Underlay: Secure the underlay using double-sided carpet tape or a staple gun.

   • Place underlay on each tread, stopping just before the stair nosing.

   • Leave a small gap at the back of the tread to prevent bulging.

     
     

3. Trim Excess: Use a utility knife to trim any excess underlay.

   
   
   
   

Step 3: Position & Secure the Stair Runner

Line things up!

1. Align the Runner: Position the runner at the top of the stairs, ensuring it is centered along the marked lines you made at the start.

   
   

2. Tack in Place: Temporarily tack the top of the runner in place with a couple of staples or tape.

Pause here: Check everything over

Fixing things in place temporarily allows you time to have a good look at the installation and ensure you're on track. If everything is lined up correctly and passes the assessment, you can carry on and fix things.

If things need tweaking, this is your opportunity to give things another go.

Remember to be honest with yourself and get the opinions of friends and family before proceeding. If there is any doubt, this is the moment you can still call in a professional to finish the job. You can be confident in the knowledge that you made a valiant attempt. If you ask me, I'd rather pass the ball and assist a goal - than never have run up the pitch.

Step 4: Staple the Stair Runner in Place

1. Secure the Top Edge:

   • If your runner starts under a stair nosing, staple it underneath the nosing first.

   • If starting at a landing, staple the runner at the top edge.

     
     

2. Work Down the Stairs:

   • Pull the runner tight against the stair riser and staple it every 2-3 inches along the edge, just beneath the stair nosing.

   • Use a knee kicker to stretch the runner snugly if needed.

     
     

3. Secure the Tread:

   • Press the runner into the stair tread, using a rubber mallet to tuck it into the corners where the riser meets the tread.

   • Staple along the edges and in the corners for extra security.

     
     

4. Repeat for Each Step: Continue down the staircase, ensuring the runner stays aligned with your centreline markings.

Step 5: Finishing Touches

1. Trim Excess Runner: When you reach the bottom step, cut off any excess runner with a sharp utility knife.

2. Secure the End: Fold the runner neatly under itself and staple it securely to the riser or use carpet tape for a cleaner finish.

3. Check for Tightness: Ensure the runner is secure and has no loose areas.

If in doubt: Work with a Certified Installer

We are only able to achieve our goals if we've refined the process. A professional has repeated these steps countless times and will ensure a smooth and swift installation. It is always advised that you work with a professional fitter for Natural Plant Fibres. Even fitting a Wool Runner, investment in the experience of someone with the knowledge and ability is a valuable one.

You can use a resource such as the NICF (national institute of carpet & floorlayers): https://nicfltd.org.uk/NICF-Directory/

There you can search for fitters that are accredited.
