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

FAQ: Installing Your Stair Runner

Can I install a stair runner myself or do I need a professional?

Yes, you absolutely can install a stair runner yourself if you're comfortable with DIY projects. This guide walks you through every step. However, if you're working with natural plant fibres or would prefer a flawless finish, a professional fitter is highly recommended.

How long does it take to install a stair runner?

For a standard staircase, DIY installation typically takes 2–4 hours, depending on experience and the complexity of your stairs. Add extra time if you're working slowly or want to ensure perfect alignment.

What tools will I need to install a stair runner?

• Measuring tape

• Pencil or chalk

• Staple gun

• Double-sided carpet tape

• Utility knife

• Rubber mallet

• Knee kicker (optional but helpful)

• Straight edge (for cutting)

Do I need to clean the stairs before installation?

Yes, it's essential that the stairs are clean and dry. Dust or debris can prevent adhesive or staples from holding properly.

I've recently painted or varnished the stairs—can I still install the runner?

Wait until all paint or varnish has fully cured, as per the manufacturer's instructions. Installing too soon could damage the finish or prevent adhesion.

Why do I need to mark a centreline?

Marking a centreline on each stair tread and riser helps you keep the runner perfectly straight throughout the installation.

Do I have to use an underlay with a stair runner?

No, underlay is optional—but it adds comfort underfoot, extends the life of the runner, and improves sound insulation.

How should I cut and place the underlay?

Cut it 3cm narrower than your runner on each side, and place it on the tread, stopping before the stair nosing. Leave a small gap at the back to prevent bulging.

How do I ensure the runner stays straight while stapling?

Align the runner with the centre marks and temporarily tack it in place at the top. Step back and check the alignment before proceeding.

Can I adjust the runner if it's slightly misaligned after starting?

Yes—if it's only tacked in place, you can remove and reposition it. This is why a preliminary check is vital.

Should I start from the top or bottom of the stairs?

Always start at the top and work your way down. It ensures a cleaner finish and allows you to keep the runner taut as you go.

How far apart should I place staples?

Staple every 2–3 inches beneath the stair nosing and again along the corners of each tread for extra hold.

Do I need a knee kicker?

It's optional but very helpful to ensure the runner is stretched tightly for a professional finish.

Can I use just carpet tape instead of staples?

Carpet tape can be used in low-traffic areas or at the edges, but staples provide stronger long-term hold, especially on staircases.

How do I finish the runner at the bottom of the stairs?

Cut any excess using a sharp utility knife. Fold the runner under itself for a neat edge and secure it with staples or strong double-sided tape.

How do I check the runner is secure?

Walk up and down the stairs and gently tug at a few areas. The runner should feel tight and snug, with no shifting or looseness.

Should I still consider hiring a professional?

For Natural Plant Fibre runners or intricate installations, yes. A professional has the tools, training, and experience to ensure a flawless result. Even for wool runners, it's a worthwhile investment.

Where can I find a certified fitter?

You can Google in your local area a term like "Carpet Fitter" or "Flooring Fitter", or use the NICF directory to find an accredited professional fitter in your area.

Are all your stair runners suitable for high-traffic areas?

Yes. Anything listed in our Stair Runner section of our store is extremely hardwearing and designed for stairs.
