How to install a stair runner

A stair runner significantly improves the look of a plain staircase, but requires some care to install properly.

Can I install a stair runner myself?

Though a carpet retailer in Chester or North Wales may include free fitting for the stair runners they sell, it's not a difficult job if you want to fit the carpet yourself. Anyone confident in their do-it-yourself skills should be able to install stair runners.

Do I need an underlay for a stair runner?

You can install stair runners without underlay, but it is recommended that you use high-quality underlay as it adds comfort and style. A stair carpet without underlay will not last as long, especially in busy places where lots of people go up and down the stairs every day.

There are three main thickness levels of underlay. Up to 6mm thick underlay allows the runner to sit flatter, but offers less cushioning. Underlay between 6mm and 9mm has a good balance between support and comfort. Using underlay above 10mm is not recommended as the extra cushioning looks bulky and could be a trip risk.

High density underlay, though more expensive, is more hard-wearing. The recommended underlay has a density of 120 kg/m3 or more and is between 6 mm to 8mm thick.

Underlay made of PU foam works well on low footfall stairs. For busy staircases, use sponge or crumb rubber underlay.

Do you need special carpet for stair runners?

You can use any type of carpet as a stair runner, but some are better than others. It pays to invest in good quality carpets, either made from wool or a wool blend. Synthetic polypropylene carpets on busy staircases can soon look flat and worn in a short time. The best carpet to use is 100% wool that keeps its shape and height and should last longer.

If it is within your budget, go for a wool or wool-blend carpet with natural thermal and insulation properties.

How should a stair runner be fitted?

First, make sure that you have measured the stairs accurately and have bought the right length and width of carpet.

If the star runner is to be fitted with a border, paint or stain the stairs before fitting the carpet. Use tape guides to mark where the edge of the carpet is placed on every step so that it is laid straight.

Next, cut the underlay in pieces that fit on each tread surface, not the vertical riser as this will add unneeded bulk. Secure them on each tread step with double-sided carpet tape or use a staple gun.

Lay the runner, wrapping it around each stair. Starting at the top, secure the runner to each stair with a staple gun to the base of each riser. A bolster chisel keeps the carpet taut before securing it.

If one runner is not enough, connect another runner, hiding the join under the tread lip and cutting off extra material.

If the runner is too long, cut the extra material from the bottom edge.
