Here’s a piece of your house you’ve walked over ten thousand times and probably never once thought about: the nosing — the rounded front edge of each stair tread that sticks out slightly over the riser below.
It’s the hardest-working piece of timber in the building. Every footstep on a staircase lands on it. It takes the full force of every descent. And it’s the difference between a staircase that looks crisp and one that looks tired.
We know more about nosings than most, because alongside fitting floors, we manufacture timber stair nosings in our own Edinburgh workshop. Here’s what they do, why they matter, and how to get them right.
What does a nosing actually do?
Three jobs.
First, safety. The nosing defines the visible edge of each step. A clearly defined edge is what your feet and eyes use to judge each step — which is why building standards care about them.
Second, protection. By taking the impact and wear at the tread edge, the nosing protects the step from splintering and rounding over.
Third, the finish. When new flooring meets a staircase, the nosing is the piece that resolves the junction — covering the cut edge of the new floor at the top landing, and giving each clad step a clean, solid front edge.
Why nosings suddenly matter: the flooring boom
Here’s the situation we see every week. A homeowner fits lovely new flooring — engineered oak, laminate, LVT — through the hall and landing. Then the staircase presents a problem.
The new floor sits 12–15mm higher than the old surface. The stair edges don’t match the new material. And the off-the-shelf aluminium or plastic trim from the flooring shop looks exactly like what it is.
A staircase carries more visual weight than almost any feature in a hallway. Finishing a beautiful floor with a cheap silver strip lets the whole job down.
A proper timber nosing — solid oak or matched hardwood, machined to suit the exact thickness of the new flooring — makes the staircase part of the design instead of an afterthought.
This is most of what our workshop does: nosings machined to match the species, tone and thickness of the floor being fitted, whether that’s our job or another fitter’s.
Off-the-shelf vs made-to-measure
Standard profiles from the DIY shed come in a handful of sizes and colours. If one happens to match your flooring thickness, riser depth and timber tone — honestly, use it.
The trouble is that staircases are the least standard thing in a house, especially in Edinburgh’s period stock, where no two treads measure quite alike.
A made-to-measure nosing is machined for your flooring’s exact thickness (so there’s no lip to trip on and no gap to flex), your tread’s proportions, and your timber and finish — oiled, lacquered or unfinished for site-matching. On the stair, that’s the difference between fitted and fudged.
- Flooring transition nosings: for landings and top steps where new flooring meets the staircase.
- Full stair cladding nosings: the key component when an existing staircase is clad in oak or laminate to match a new floor.
- Replacement nosings: for repairing worn or damaged treads on period staircases without replacing the stair.
- Contract profiles: for commercial and communal stairs, where defined edges and durability rules apply.
Cladding: the smarter staircase makeover
The biggest staircase trend in the UK right now isn’t replacement — it’s cladding. Fitting new oak or flooring-matched surfaces over the existing structure.
Your staircase’s bones are almost certainly fine. It’s the surfaces that are tired. Cladding treads and risers, with proper nosings at every edge, transforms a staircase for a fraction of the cost and disruption of ripping it out — typically £2,000–£5,000 for a standard flight, against £10,000+ for structural replacement.
It’s also the route that lets a staircase match new flooring exactly, because the cladding can be made from the same material.
The safety details worth knowing
Two things from the regulations side, in plain English.
Step edges should be clearly visible. On private stairs this is common sense — avoid finishes that camouflage the edge, and light the stair decently. On communal and commercial stairs it’s a requirement, usually met with visually contrasting nosings.
And consistency matters more than any single measurement. Feet learn a staircase within three steps, so a nosing that projects differently, or one tread that ends up a different height after cladding, is how trips happen.
That’s the strongest argument for having stairs done by people who do stairs. The tolerances are tighter than flooring, and everything is on show.
How to get it right on your project
- Fitting new flooring up to a staircase? Decide the stair treatment before the floor is fitted, not after. Heights and transitions should be planned as one job.
- Cladding a staircase? Ask to see the nosing profile and material sample before committing. It’s the piece you’ll see and touch most.
- Repairing a period stair? Original nosings can often be replicated rather than replaced with something generic. Worth asking before anyone reaches for a standard profile.
- Trade? We supply made-to-measure timber nosings to other fitters and joiners — machined to your spec, in the species and finish your job needs.
