Stair Runner Guarantee: What to Check Before You Buy

A guarantee on a stair runner provides peace of mind, but only if you know what it actually covers. For a 13-step flight (10 in / 25 cm treads, 7.5 in / 19 cm risers), requiring 23-24 ft (7-7.3 m) of runner, a good warranty can be a significant protection against early wear.

Start with the numbers: our stair runner calculator also works as a stair runner length calculator, adding nosing wrap, landings, winders, pattern repeat and waste so you order the right length first time.

What warranties typically cover

Most stair runner warranties cover manufacturing defects—issues with the weave, the backing, or the colour consistency. They rarely cover 'wear and tear', which is defined as the thinning of the pile due to foot traffic over time. Understanding this distinction is vital.

Common exclusions

Exclusions often include failure to use a recommended underlay, improper cleaning, accidental spills, or damage caused by pets. They might also require proof of professional installation.

How much runner do I need?

For a 13-step flight: 10 in tread + 7.5 in riser + 0.75 in wrap = 18.25 in per step. Total 237.25 in. Adding 24 in for finishing = 261.25 in (21.77 ft). Including a 10% safety margin, order 24 ft. Metric: 25 cm tread + 19 cm riser + 1.9 cm wrap = 45.9 cm per step. Total 596.7 cm, plus 60 cm = 656.7 cm. With 10% safety, aim for 7.3 m.

Keep your receipts

Your proof of purchase and a receipt for professional installation are your 'keys' to any warranty claim. Keep these in a safe place.

  • Confirm if the warranty is transferable (unlikely).
  • Ask what happens in the event of a successful claim.
  • Understand the process for reporting a fault.
  • Keep your original order details and fitting receipt.

Why fine print is everything

A '10-year guarantee' sounds great, but if it excludes all the ways a runner typically fails on a staircase, it is essentially worthless. Read the warranty document as carefully as you would a contract before you buy.

Whatever you decide, get the numbers first: the stair runner calculator doubles as a stair runner length calculator, adding nosing wrap, landings, winders, pattern repeat and waste so you order the right length the first time.

Frequently asked questions

Does the warranty cover pet damage?

Almost never. Pets are one of the most common causes of premature wear on runners.

Is professional fitting required?

Often, yes. Many manufacturers will deny a claim if they can prove the runner was installed incorrectly.

Does the warranty cover colour fading?

Only if the fading is caused by a manufacturing defect. Sunlight fading is usually considered natural wear.

Can I do the maintenance myself?

Yes, but you must follow the manufacturer's recommended methods. Using a harsh chemical cleaner will likely void your coverage.

Is it worth paying more for a better warranty?

If the product quality is higher, yes. If it's just the warranty, assess the likelihood of needing it.

What should I do if I need to claim?

Gather your proof of purchase, photos of the issue, and your professional fitting receipt, then contact the retailer.

How are claims settled?

Usually by repairing or replacing the affected part of the runner, not by replacing the entire staircase length.

Should I save the care instructions?

Absolutely. These often contain the 'how-to' for the warranty coverage.
