A worn, scratched or grey hardwood floor can make a whole room feel tired — and most people assume the only fix is a full tear-out. It usually isn’t. Here’s how to tell whether your floor can be saved, and what each path really costs in Québec.
Updated October 2026
Quick answer
In most homes, a solid hardwood floor can be refinished — and refinishing typically costs a fraction of replacing it, often several times less, because you reuse the wood that’s already down. You only need to replace when the boards are structurally damaged, the wear layer is sanded through, or you genuinely want a different floor. The only way to get a real number is an on-site look — and ours is free.
Why most worn floors don’t need to be replaced
Here’s the part that surprises people: almost everything you dislike about a tired floor lives in the very top of the wood. Surface scratches, dullness, grey or worn traffic lanes, pet marks and old yellowed varnish all sit in a thin layer at the surface.
Sanding removes that layer and exposes fresh, clean wood underneath — the same wood that looked beautiful the day it was installed. That’s what sanding and varnishing does: it resets the floor rather than replacing it.
And you can do it more than once. According to the National Wood Flooring Association (NWFA), most solid wood floors can be sanded six to eight times over their life, and thick ¾-inch boards sanded carefully can often handle more. A solid floor that’s cared for can outlast the people who installed it.
The 5-minute test: can YOUR floor be refinished?
You can get a good first read on your own floor in a few minutes. Run through this checklist:
- Solid or engineered? Look at the edge of a board at a doorway threshold, or down into a floor heating vent. Solid boards are the same wood all the way through. Engineered boards show thin plywood-like layers under a top layer of real wood.
- How thick is the wear layer? On solid wood there’s plenty. On engineered wood, only that top real-wood layer can be sanded.
- Has it been sanded before? If you can see nail heads sitting at the surface, or the tongue-and-groove edge of boards is starting to show, there may be little wood left to remove.
- Any water damage? Cupping (edges higher than the middle), crowning (middle higher than the edges), black stains, or soft spots underfoot all point to moisture problems.
- Are boards loose, squeaky or soft? A little squeak is normal. Movement, sponginess or boards lifting at the ends can mean the problem is below the surface.
Engineered floors need a closer look. The NWFA advises against sanding engineered wood where the wear layer is thinner than 3/32 inch (2.38 mm) — there simply isn’t enough real wood to work with. A thin wear layer usually means replacement, or at most a “screen and recoat.” (A screen-and-recoat lightly scuffs the existing finish and adds a fresh protective coat — no full sanding, so it refreshes the look but can’t remove deep scratches.)
Not sure what you’re looking at? That’s normal — and it’s exactly what an on-site visit is for. We’ll tell you honestly whether your floor can be saved before you commit to anything.
When replacing really is the better option
We’d rather save a floor than tear it out — but sometimes replacement genuinely is the smarter call. Replace when:
- The wear layer has already been sanded through and nail heads or board edges are exposed.
- There’s widespread water damage or rot, or the subfloor underneath has failed.
- The floor is laminate or vinyl — these are printed surfaces, not real wood, and cannot be sanded at all.
- You want a completely different species, board width or look that refinishing can’t deliver.
It’s rarely all-or-nothing, though. If only part of a floor is damaged, repairing and blending the affected boards and then refinishing the whole room is often the middle path — you keep most of your original floor and spend far less than a full replacement. And when a new floor really is the answer, we also handle hardwood installation in oak, maple, cherry, ash and beech.

Your options, from a refresh to a full replacement
Here’s the honest money picture without made-up numbers: refinishing a floor you already own typically costs a fraction of replacing it — often several times less. You’re reusing the wood that’s already down and paying mostly for labour, while replacement means buying all-new material and paying to tear out the old floor and install the new one. That’s why a new floor sits at the top of the range and a refinish sits near the bottom.
| Option | What’s included | Best for |
|---|---|---|
| Sanding only (no finish) | Machine sanding down to bare wood, without stain or varnish | Floors having a finish applied as a separate step |
| Full refinish (sand + stain/varnish) | Sanding plus stain and protective coats, depending on condition and finish | Most worn, scratched or dull solid floors |
| New solid hardwood installation | New wood supplied and laid in your choice of species, grade and board width | Choosing a brand-new floor |
| Full replacement | Tear-out of the old floor, new wood, installation and any subfloor work | Floors past saving, or a complete change |

Refinishing also keeps the character of an original floor that a new one can’t copy. One thing to keep in mind: factory pre-finished floors take a little more work to sand, because their tough aluminium-oxide coating is harder to cut through.

What refinishing does for resale value and the environment
A freshly refinished hardwood floor shows beautifully — it’s one of the first things buyers notice, and it makes a whole home feel cared for. You can see the difference a refinish makes across our project gallery.
There’s an environmental upside too. Keeping and refinishing a solid floor avoids tearing out and landfilling good wood that still has decades of life in it. And we finish with low-VOC, odourless, Quebec-made Finitec products, so the refresh is gentle on your indoor air as well. Refinishing is also far less disruptive than a full tear-out: there’s no demolition, nothing to haul to the landfill, and far less time with your rooms out of use — most projects wrap up in a few days. If you’re weighing colours and sheen, our guide to choosing the right finish walks through the options.
Frequently asked questions
How many times can a hardwood floor be refinished?
A solid hardwood floor can typically be sanded many times over its life — the industry association NWFA estimates six to eight, and thick ¾-inch boards sanded carefully can often handle more. Each refinish removes only a thin layer of wood, so a well-kept solid floor can last for generations.
Can engineered hardwood be sanded?
It depends on the thickness of the top real-wood wear layer. The NWFA does not recommend sanding where that layer is under 3/32 inch (2.38 mm). A thicker wear layer can usually take a light sanding once or twice; a thin one is better suited to a screen-and-recoat or replacement. We can measure it for you on-site.
Can you refinish only one room or one damaged area?
Yes. Floors are usually refinished room by room. Spot-refinishing a single damaged patch can leave a visible line where new finish meets old, so a full room blends best. We can also repair and blend individual damaged boards before refinishing the whole space.
Can I change the colour of my floor when refinishing?
Yes. Once the floor is sanded to bare wood, a stain can take it lighter or darker before the protective coats go on. The final colour depends on the wood species as much as the stain, so a test patch is always worth doing — our guide to finishes explains how colour and sheen work together.
How do I know if my floor has water damage under the finish?
Look for cupping (board edges higher than the centre), crowning (the centre higher than the edges), dark or black staining, soft or spongy spots underfoot, and a musty smell. Some water damage only reveals itself once the old finish is sanded off, which is why an on-site check matters before any work begins.
The honest bottom line
If your floor is solid wood and the surface is simply worn, scratched or dated, refinishing is almost always the better value — and the more sustainable choice. Replacement is for floors that are structurally gone, or when you truly want something different. If you’re still deciding, our next read covers what the work is actually like: how long does hardwood floor refinishing take, and can you stay home during it?
We refinish floors across the West Island and nearby — including Pointe-Claire, Kirkland and Dollard-des-Ormeaux. And our 97% dustless sanding keeps the whole process clean from start to finish.
