Stairs are slower and fussier than an open room. Every step is cut and fitted on its own, the surface has to grip as well as it looks, and anything that adds thickness must keep the steps even from bottom to top. Balusters and handrails may have to come off and go back on just as solidly.
This page covers refinishing, capping and replacing, material options, even riser heights, nosings and handrails, slip resistance and runners. The staircases page covers building and rebuilding the stair structure.
Refinish, cap or replace: three ways to renew stair treads and risers
The right approach depends on what's under the current finish, how even the steps already are and how much extra height the stair can take.
- Refinishing: sound solid hardwood treads are sanded or stripped and recoated, keeping the original wood and adding no height; older painted stairs should be tested for lead first, as the hardwood refinishing page explains.
- Capping: new tread and riser covers in hardwood, vinyl or laminate are bonded and fastened over the existing steps after the old nosing is cut back flush, a common fix when carpet comes off rough construction-grade treads.
- Replacing: the old treads and risers come off the stringers and new ones go on, which gives the cleanest result and a chance to cure squeaks without adding thickness.
- Carpeting: new stair carpet or a runner goes over sound treads, the least disruptive option when the wood underneath isn't worth showing.
Stair flooring materials: hardwood treads, carpet, vinyl and laminate stair nosing
- Hardwood: solid treads or caps in oak, maple or a species matched to the floor, durable and refinishable, though slippery in socks without the right finish.
- Prefinished stair parts: treads, risers and nosings made to match a prefinished floor, which avoids sanding, staining and finish fumes inside the house.
- Vinyl plank: glued to each tread and riser with a matching vinyl or metal nosing, because a floating click floor can't be used on steps.
- Laminate: glued down with a matching stair-nose moulding, since the planks can't be shaped around an edge; that moulding is the weak point and must be firmly bonded and fastened.
- Carpet: warm, quiet and grippy, installed full width or as a runner, with installation styles compared on the carpet installation page.
Keeping stair riser heights even when new tread layers go on
Most stair flooring leaves the structure alone, but added thickness changes step heights unless it's planned. Capping every tread raises all the middle steps by the same amount, so their risers stay equal, yet the bottom step gets taller and the top step shorter unless the floors at each end rise by the same amount. The one step that differs from the rest is where people misstep, because the body expects every rise in a flight to match.
Stairs in houses fall under Part 9 of the National Building Code of Canada or the provincial code based on it, which regulates the rise and run of steps and how uniform they must be; the staircases page explains which edition applies. Rather than relying on a rule of thumb, the installer should measure the whole flight, plan tread, landing and floor thicknesses so the finished risers stay even, and confirm with your municipality whether a permit is needed. When the numbers don't work, replacing treads usually solves it better than stacking another layer.
Stair nosings, balusters and handrails during a stair flooring job
The nosing is where the foot lands going down, so it takes the most wear and carries the most risk. On new or capped stairs it's either part of a solid tread or a separate moulding fastened to the front edge, and it should overhang each riser by the same amount and feel solid when you press on it with your heel.
- Balusters and newel posts that sit on the treads often have to come out so new treads or caps can be fitted, then be reinstalled or replaced to suit the new height.
- A handrail taken down for the work goes back on anchorage at least as solid as before, never into drywall anchors alone.
- Raising the treads slightly changes the handrail's height above the nosings, so the installer checks it along the whole flight.
- Skirt boards along the wall are scribed or replaced so new treads meet them without gaps.
- Open-sided stairs get return nosings on the exposed end of each tread for a finished edge.
- In a home with children or older adults, a stair shouldn't be left overnight without its guard or handrail.
Slip resistance on stairs: finishes, nosing grip and preventing falls
The Public Health Agency of Canada's falls-prevention guide calls for solid handrails on both sides of a stairway, warns that scatter mats are tripping hazards unless they're non-slip, and advises using the non-skid kind if you wax floors. On stairs, grip starts with the finish: a satin or matte coat gives socks and slippers more hold than high gloss, and treads should never be waxed or polished to a shine.
- Vinyl and laminate stair nosings with a grooved or textured top grip better than smooth ones.
- Loose tread mats or pads should be removed or replaced with ones fastened firmly to each step.
- Clear anti-slip strips or adhesive treads can be added to existing hardwood, at some cost to the look.
- Older dogs struggle on glossy treads too, and a runner or textured finish helps them as much as people.
Carpet runners on stairs: reveals, fastening and stair rods
A runner leaves a strip of finished wood showing on each side of the carpet, so it suits stairs whose treads and risers are worth seeing. Because those edges stay visible, the wood is refinished or painted before the runner goes down, and the runner has bound or serged edges rather than a raw cut.
- Fastening: the runner is stretched over pad cut a little narrower than the carpet and held with tack strips, staples or both, so it can't creep.
- Stair rods: rods across the base of each riser are mostly decorative today, and the runner still needs fastening underneath.
- Reveals: the runner is centred with equal wood showing on each side, planned around balusters and the skirt board.
- Winders and landings: turning stairs need the runner cut, seamed or folded at each change of direction.
- Replacement: a runner wears at the nosings first and can be swapped without touching the wood beneath.
Stair Flooring: frequently asked questions
Can laminate or vinyl plank be installed on stairs?
Yes, but not as a floating floor. Each tread and riser is glued down and a matching stair nosing is fastened at the front edge. Check that the product's instructions cover stairs.
Can hardwood go over carpeted stairs?
Not over the carpet itself. The carpet, pad, tack strips and staples come off first, then the treads are capped or replaced, with thicknesses planned so the bottom and top steps still match the others.
Should stair treads match the hardwood floor?
Usually, in species and colour, so the stair reads as part of the floor. Prefinished floors often have matching stair parts, while site-finished stairs can be stained on site to match. Painted risers with wood treads are a common, forgiving combination.
Do I need a permit for new stair flooring?
Refinishing or covering treads on the same stair usually doesn't need one, but your municipality decides, and work that changes step heights, guards or handrails can bring code rules into play. Ask before the work starts.
Why is my stair nosing coming loose?
Usually the adhesive didn't bond, the fasteners were too few or too short, or a floating product was used on the stair. The nosing should come off, the surfaces be cleaned, and it be re-glued and fastened as its maker directs.
