The night before: what to have sorted
On every job I've fitted, the ones that run smoothly have one thing in common: the client did the prep the night before, not the morning of. Clear the stairwell of rugs, runners, plants on the windowsill above the stair, pictures leaning against the stringer, anything that could get knocked or catch dust. Move furniture that blocks the top or bottom landing, since a fitter needs a clear run to carry a roll of carpet up without wrestling it round a chair. If you have pets, arrange somewhere for them to be during the day, since an open staircase with tools and offcuts lying around is not a safe space for a curious dog or cat.
Confirm the fabric has actually arrived and been checked before the fitter's van turns up. It sounds obvious but I've had jobs delayed because a delivery was still sitting in a warehouse the fitter assumed had already been dispatched to site. If you ordered rods, gripper or underlay from a separate supplier to the runner itself, double-check all of it is physically present, not just ordered, the day before.
Fitting day: what happens and roughly how long it takes
| Stage | Straight flight (13 steps) | With winders or landing |
|---|---|---|
| Clear access and lay dust sheets | 10-15 min | 10-15 min |
| Fix gripper or tackless strip | 20-30 min | 30-45 min |
| Fit underlay/pad per step | 30-45 min | 45-60 min |
| Cut and fit runner | 1.5-2.5 hrs | 2.5-4 hrs |
| Fit rods, if used | 20-30 min | 30-45 min |
| Final checks, tidy up | 15-20 min | 20-30 min |
| Total | 3-4.5 hrs | 4.5-7 hrs |
Keep the area clear while the fitter is working
It's tempting to hover and chat, but a stairwell is a genuinely narrow working space with a knife, staple gun and offcuts around. Keep children and pets away from the stairs entirely until the fitter confirms the job is finished and the area is clear.
How much runner do I need?
Confirming metreage before fitting day, rather than discovering a shortfall halfway through, avoids the single most disruptive delay a fitting day can have. On a US flight of 13 steps with a 10 in tread run and 7.5 in riser height, plus a 0.75 in nosing wrap per step, that's 18.25 in per step, 237.25 in (19.77 ft) across 13 steps, plus a 24 in finishing allowance for 261.25 in (21.77 ft), and with an 8% waste margin for a fitting day that includes some pattern matching, you land at roughly 23.5 ft.
In UK metric terms, 25 cm tread run and 19 cm riser height with a 1.9 cm nosing wrap gives 45.9 cm per step, 596.7 cm across 13 steps, plus a 60 cm finishing allowance for 656.7 cm, and an 8% waste margin brings the total to about 7.09 m. Run your own numbers through the stair runner calculator the week before fitting day so any shortfall is caught while there's still time to order more, rather than on the day itself when the fitter's schedule has no slack for a delay.

Open the stair runner calculatorChecklist to run through with your fitter before they start
- Confirm the runner width and centring is what you agreed, before the first staple goes in.
- Check the direction of any pattern or pile so it runs consistently up the flight.
- Agree how winders or the landing will be handled if your stair has either.
- Confirm whether existing gripper will be reused or replaced.
- Ask about noise, dust and how long each stage is expected to take, so you can plan your day around it.
- Walk the finished flight together before the fitter packs up, checking every step individually.
During the fit: questions worth asking as it progresses
It's fine to check in periodically, especially at natural breaks like after the gripper's fixed and before the runner itself goes down, since that's the last easy point to change your mind on centring or width without unpicking finished work. Ask to see how a winder or the landing is being handled if your stair has one, since there's more than one acceptable method and it's worth understanding which your fitter is using and why.
If anything looks off partway through, a step that seems to be pulling to one side, a colour that reads differently on the stair than it did in the shop, raise it there and then rather than waiting until the whole flight is finished, since some issues are far easier to correct mid-job than after every staple is in.
After the fitter leaves: what to check that day
- Walk every step, checking for lift, movement or an uneven edge along the stringer.
- Check the top and bottom finishing points are neat and securely tucked or bound.
- Look along the runner's centre line from top and bottom to confirm it's straight and evenly positioned.
- Vacuum lightly to remove any lint or offcut fibres left from cutting.
- Keep the area free of heavy foot traffic for the rest of the day if any adhesive was used and needs to cure.
If something needs revisiting
Most reputable fitters will come back to address a genuine snag, a slightly proud edge, a stitch that's caught, without argument, provided you flag it within a few days rather than months later after the issue has been walked on repeatedly. Take photos on the day if you spot anything you're not sure about, since a photo from day one is much more useful evidence than a description given weeks after the fact.
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
How long does it take to fit a stair runner in one day?
A straightforward 13-step straight flight typically takes 3-4.5 hours. A staircase with winders or a landing usually takes 4.5-7 hours because of the extra cutting and pattern matching involved at each turn.
What should I clear before installation day?
Clear rugs, plants, pictures and any furniture blocking the top or bottom of the stairwell the night before, not the morning of. A clear run lets the fitter carry the roll up without wrestling it around obstacles, which saves real time.
Should I be home during the fitting?
It's generally helpful to be available for the start and the final walkthrough, but you don't need to watch the whole job. Keep children and pets away from the stairs while tools and offcuts are out for safety reasons.
What if my runner arrives short on the day?
This is exactly what confirming metreage the week before is meant to prevent. If it happens anyway, a good fitter will fit what they can and schedule a return visit rather than leaving the job half-done, but it's an avoidable delay with better prep.
Can a stair runner be fitted over old gripper?
Sometimes, if the existing gripper is sound and correctly positioned for the new runner's width. A fitter will check this during the survey or at the start of the job and replace it if it's worn, misplaced or the wrong type.
How soon can I walk on a newly fitted stair runner?
Usually straight away for a stapled or tackless-strip fit. If any adhesive was used at edges or a landing join, avoid heavy traffic for a few hours while it cures, and check with your fitter for the specific product's guidance.
What should I check immediately after the fitter leaves?
Walk every step checking for lift or movement, check the top and bottom finishing points are neat, and sight down the centre line from both ends to confirm it's straight. Flag anything unusual the same day while it's easy to fix.
Will fitting be noisy or dusty?
There's some noise from a staple gun or hammer and some dust from old carpet or gripper removal, more if you're replacing an existing runner. It's worth planning quieter activities elsewhere in the house during the main fitting hours.
