Start With What You Own
Most homeowners who call us about a tired hardwood floor assume they are buying a new one. In older Calgary homes especially — the 1950s and 60s bungalows in the southwest and northwest, the 1990s two-storeys with oak main floors — the existing floor is usually salvageable, and renewing it produces a better result than replacing it with a new product of similar cost.
So the honest sequence is: work out what is wrong, work out whether the wood is sound, and only then discuss replacement.
The Three Options, Ranked by Cost
1. Screen and recoat. The existing finish is lightly abraded and one or two fresh coats applied. No wood is removed. It renews a dull, lightly scratched surface quickly and cheaply. It cannot remove deep scratches, stains or the existing colour, and it does not work over wax finishes.
2. Full sand and refinish. The floor is sanded back to bare wood, repaired where needed, optionally stained, and sealed with several coats. This removes scratches, grey traffic lanes and the old colour entirely. It is the option that transforms a floor.
3. Replacement. New material, removal and disposal of the old floor, new installation. The most expensive route, and sometimes the only honest one.
Our refinishing page covers the first two in detail.
When Refinishing Wins
Refinishing is the right answer when:
- The wood is solid, or engineered with a thick enough wear layer.
- Damage is in the finish rather than the wood — scratches, dullness, grey lanes, a dated colour.
- The floor is flat and stable, with no active moisture problem.
- The layout still works for the home.
- There is enough wood above the tongue for another sanding.
This describes most of the tired hardwood in Calgary. A floor covered by carpet for twenty years often looks dreadful when uncovered — tack-strip holes at the perimeter, staple marks, grey oxidation — and comes back beautifully with one sanding. The holes hide under baseboard; the marks sand out; the grey is old finish, not damaged wood.
When Board Replacement Wins
Sometimes a floor needs surgery rather than a full replacement:
- Black stains from pet urine or standing water, which sanding will not reach.
- Cracked, split or water-damaged boards in a limited area.
- A strip where a wall was removed during a renovation.
- Localized buckling after a resolved leak.
New boards are cut in with staggered joints, matched for species, width and thickness, and the room is refinished afterwards so the repair blends. Done properly, it becomes invisible. Our hardwood floor repair page covers the technique.
The Five Cases Where Replacement Is Honest
1. The floor has been sanded too many times. If fasteners are near the surface or the tongue is exposed, there is nothing left to work with.
2. Engineered wood with a thin veneer. Sanding through a 1 to 2 mm veneer ruins it permanently. A screen-and-recoat may be possible; a full sand is not.
3. Damage across most of the area. Replacing 60% of a floor board by board costs more than replacing all of it, and the result is less consistent.
4. Severe, unresolved moisture problems. If the floor is still reacting to a damp basement or crawlspace, no repair will hold until the cause is fixed — and sometimes the wood is too far gone by then.
5. You want something different. A floor can be structurally perfect and still be the wrong product for the room — solid hardwood in a basement, for instance, or narrow strip in a home being opened up to wide-plank proportions.
The Cost Comparison, Concretely
New hardwood in Calgary runs $8 to $16 per square foot installed, plus removal at $0.50 to $3 and subfloor preparation at $1 to $4 per square foot where needed. Stairs add $80 to $150 per step.
Refinishing is quoted by area and scope. It has no material cost beyond finish, no removal and no disposal, which is why it consistently lands well below replacement for the same room. A screen-and-recoat costs less again.
On a 900 square foot main floor, that difference is usually thousands of dollars — which is why we price both routes at the estimate rather than asking you to take our word for it. The full pricing picture is in our hardwood cost guide.
What Gets Checked Before We Recommend
At an estimate visit for a tired wood floor, four things settle the question:
- Thickness above the tongue, which determines how many sandings remain.
- Evidence of previous sanding, visible at vents, thresholds and edges.
- Moisture readings where cupping, staining or a basement below suggests a problem.
- Extent of damage, counted in boards rather than described in adjectives.
With those four answers, the recommendation is usually obvious — and when it is genuinely borderline, we price both and let the numbers decide.
What Refinishing Actually Involves
Homeowners often picture refinishing as a single day of sanding. It is a sequence, and knowing it helps you plan around it.
Assessment and repairs first. Loose boards re-secured, damaged boards replaced, protruding fasteners set below the surface. Everything left in the floor gets locked under the new finish, so repairs never come second.
Coarse sanding. The old finish comes off and the surface is levelled. This is the dustiest stage, and modern dustless systems connect the sanders to vacuum units that capture most of it at the source.
Progressive grits. Finer abrasives refine the surface, with edgers and corner tools reaching what the large machines cannot.
Colour test. If you are staining, samples go on your actual floor and are viewed in your own light before the whole room is committed. Wood species affects the result, so a sample board from a store is not a reliable preview.
Stain and finish coats. Stain dries fully, then multiple coats of finish go on with abrasion between coats as the product requires.
Curing. Light foot traffic first, then furniture, then rugs last — the finish keeps curing after it feels dry, and covering it too early can mark it permanently.
Water-based finishes dry faster and smell far less than oil-modified ones, which matters in a Calgary winter when opening windows for ventilation is not practical.
The Case for Acting Sooner
There is one argument for not waiting. While damage is confined to the finish, refinishing restores the floor completely. Once the finish wears through and dirt and moisture reach the bare wood, the grey staining works into the grain, and even a full sand may not remove all of it.
A screen-and-recoat every several years is inexpensive and keeps a floor in the cheap-repair category indefinitely. Waiting until the traffic lanes are grey moves it toward the expensive one.
If you are unsure which category your floor is in, a free estimate includes the assessment — no deposit, no obligation, and a straight answer either way.
