About hardwood refinishing services
Solid hardwood is one of the few floor coverings you can restore instead of replace. Over years of foot traffic, sliding chairs, pet claws and sunlight, the surface finish dulls, greys and collects scratches that no amount of mopping will fix. Refinishing a hardwood floor removes that worn top layer, exposes clean raw wood underneath, and seals it again with a new coat of protection. Because the sanding only takes off a thin sliver, a well-built solid floor can be refinished several times across its lifetime, which is why century homes across Canada still show off their original planks.
Homeowners usually start searching for hardwood floor refinishing when the damage is more than cosmetic. Bare patches where the finish has worn through, water staining near entries, deep gouges and boards that feel rough underfoot all point to a floor that needs recoating or a full sand. The good news is that refinishing is far less disruptive and less expensive than tearing out and installing new flooring, and it keeps the character of wood you cannot easily buy today. It is also one of the higher-return interior projects when you plan to sell.
Not every floor is a candidate, and part of a contractor's job is telling you honestly which route makes sense. Thin engineered hardwood with a paper-thin wear layer may only tolerate a light screen and recoat rather than an aggressive sand. Floors that have already been sanded down to the tongue, or that have widespread rot and cupping from moisture, are better replaced. A good refinisher inspects board thickness, checks for movement and squeaks, and measures moisture before quoting, so you are not paying to sand a floor that cannot take it.
Hardwood Refinishing services we cover
Full sand and refinish
The complete process: drum or belt sanding down to bare wood, edging along walls, multiple grit passes, then new stain and protective topcoats. This erases deep scratches, old finish and most surface stains for a like-new floor.
Screen and recoat
A light buff of the existing finish followed by a fresh maintenance coat. Ideal when the wood itself is sound but the topcoat looks dull. Far faster and cheaper than a full sand, with much less dust.
Stain colour change
Sanding to raw wood then applying a new stain to shift from honey oak to a modern grey, walnut or natural matte look. Contractors sample colours on your actual boards first, since species take stain differently.
Board repair and weaving
Replacing cracked, water-damaged or missing boards and blending new pieces into the existing field before finishing, so repairs disappear rather than stand out as an obvious patch.
Dustless refinishing
Sanders connected to sealed containment vacuums capture the vast majority of airborne dust at the source, keeping fine particles out of your cabinets, vents and living space during the job.
Engineered floor recoating
Gentle screening and recoating tailored to the thinner wear layer of engineered hardwood, restoring sheen and protection without cutting through to the plywood core beneath.
Signs you need a hardwood refinishing pro
Grey or bare traffic paths
When walkways look washed out or you can see raw, greying wood where the finish has worn through, the protective layer is gone and moisture is starting to reach the wood itself.
Water sitting rather than beading
Drip a little water on the floor. If it soaks in and darkens the wood instead of beading up, the seal has failed and the boards are vulnerable to staining and warping.
Deep scratches and gouges
Fine surface scuffs can be buffed out, but scratches you can feel with a fingernail, or gouges that catch dirt, generally need a full sand to remove.
Dull, cloudy or flaking finish
A topcoat that looks hazy, shows white cloudy patches or is peeling in spots has broken down and can no longer be revived by cleaning alone.
What drives hardwood refinishing cost
See the full cost guide →Floor area and layout
Pricing is largely driven by square footage, but small rooms, lots of closets, stairs and tight corners slow the work because edging by hand takes longer than sanding open floor, raising the rate per area.
Full sand versus recoat
A screen and recoat costs a fraction of a full sand because it skips the multi-grit sanding and raw-wood prep. The condition of your existing finish decides which one you actually need.
Wood species and finish choice
Harder or exotic species take longer to sand, and premium finishes such as low-VOC water-based coats or hardwax oils cost more than standard oil-based polyurethane but cure faster and smell less.
Repairs and stain changes
Weaving in replacement boards, filling gaps, fixing squeaks and switching stain colours all add labour and materials beyond a straightforward clear refinish over sound wood.

Hardwood refinishing in the United States
the United States is a big market for hardwood refinishing, and it is anything but uniform. From Gulf-coast humidity to northern winters, conditions across the United States vary enough that materials and methods are matched to the local climate.
Typical jobs include full sand and refinish and stain colour change. Because permitting and code differ by state and municipality, a local pro keeps the job compliant and on schedule.

How to choose a hardwood refinishing contractor
Hardwood refinishing is not a licensed trade the way electrical or gas work is, so the burden falls on you to confirm a contractor is properly insured and experienced. Ask for proof of general liability insurance and, if they have employees, workers' compensation coverage through your provincial board such as WSIB in Ontario or WorkSafeBC. This matters because industrial sanders, solvents and dust are involved, and you do not want liability landing on your household if someone is hurt or your floor is damaged. Membership in the National Wood Flooring Association or a provincial flooring association signals ongoing training, and many reputable refinishers carry manufacturer certification for the specific finish systems they apply.
Beyond paperwork, judge a refinisher by their prep and their references. The quality of a finished floor is decided during sanding, so ask how they handle dust containment, how many grit passes they run and whether they hand-scrape edges and corners. Request addresses or photos of floors they refinished a year or more ago, since a fresh floor always looks good but only time reveals swirl marks, bubbles and premature wear. Get the finish product, number of coats and cure time in writing, and confirm who moves furniture and appliances. A contractor who walks your floor, checks board thickness and sets realistic drying expectations is worth more than the lowest bid.
What to expect from a hardwood refinishing project
Assessment and moisture check
The contractor inspects board thickness, looks for cupping, squeaks and past sanding, and measures moisture in the wood and subfloor to confirm the floor can be sanded and will accept finish properly.
Clear and prep the room
Furniture and appliances come out, vents and doorways are sealed against dust, and any loose boards, protruding nails or gaps are secured and filled before sanding begins.
Multi-grit sanding and edging
Coarse to fine grit passes with a drum or belt sander flatten the floor and remove old finish, while edgers and hand scrapers reach walls, corners and stairs the big machine cannot.
Stain and finish coats
After a thorough vacuum and tack, optional stain is applied and allowed to dry, followed by two or more protective topcoats with light buffing between coats for a smooth, even sheen.
Cure and reoccupancy
You can usually walk on the floor in socks within a day, but furniture and rugs must wait longer while the finish fully cures and hardens to its final durability.
Hardwood Refinishing: frequently asked questions
How much does hardwood floor refinishing cost?
Cost depends mainly on floor area, whether you need a full sand or just a recoat, the wood species and your choice of stain and finish. A light screen and recoat is far cheaper than sanding to bare wood, and extras like board repairs, stain colour changes and stairs add to the total. Get a few itemized quotes based on an in-person measure rather than a phone estimate for an accurate number.
How long does refinishing hardwood floors take?
A typical single room takes two to four days from sanding to the final coat, and a whole main floor can run most of a week. The variable is drying and curing time between coats, which stretches with oil-based finishes and cool, humid weather. A screen and recoat with no stain can sometimes be done in a single day. Ask your contractor for a room-by-room schedule.
How many times can hardwood be refinished?
A solid hardwood floor can usually be fully sanded and refinished several times over its life because each pass removes only a thin layer above the tongue and groove. Engineered hardwood is limited by its thinner wear layer and may only tolerate one full sand or a few light recoats. A contractor can measure your board thickness to tell you how much life is left.
Can you refinish hardwood floors without sanding?
Yes, if the wood itself is sound and only the finish is dull, a screen and recoat lightly abrades the existing topcoat and adds a fresh maintenance coat without going to bare wood. This will not remove deep scratches, stains or grey worn areas, though. If the finish has worn through in traffic paths, a full sand is the only lasting fix.
How long before I can walk on refinished floors?
You can typically walk on the floor in socks about a day after the final coat, but you should keep pets, shoes and furniture off longer. Water-based finishes cure faster than oil-based ones. Full hardness takes a couple of weeks, so wait before replacing area rugs, which can trap solvents and leave marks in a finish that has not fully cured.
Is refinishing hardwood floors worth it?
For solid hardwood in decent structural shape, refinishing is almost always worth it. It costs far less than replacement, preserves character you cannot easily buy, and consistently ranks among the better-returning interior upgrades when selling. Replacement makes more sense only when boards are rotted, badly cupped from moisture, or already sanded down to the tongue and can no longer take another pass.
