The Short Answer
Yes — luxury vinyl plank and SPC flooring can be installed directly over existing hardwood or engineered wood, and in most Calgary homes that is the right way to do it. A rigid-core plank floats: it is not nailed or glued to anything, so it does not care what is underneath as long as that base is flat, dry, solid and firmly fastened.
Four conditions decide whether your particular floor qualifies:
- Flat — within roughly 3/16 inch over 10 feet, with no board-to-board steps.
- Dry — no active moisture, and wood moisture content in a normal range.
- Solid — no loose boards, no spongy areas, no movement underfoot.
- Firmly fastened — the hardwood is still attached to the subfloor, and the subfloor to the joists.
Fail any one of them and the fix is usually straightforward. Ignore any one of them and the new floor inherits the problem permanently.

Why This Is Such a Good Deal
Tear-out is the hidden cost of a flooring project. Removal and disposal runs $0.50 to $3.00 per square foot in Calgary, and hardwood sits at the top of that range: every board is nailed, the nails have to come out or be flattened, there is real dust, and the debris is heavy enough to matter at the landfill.
Leaving the hardwood in place deletes that line from the estimate. On a 900-square-foot main floor, that is somewhere between $450 and $2,700 you never spend. Our flooring removal page explains what drives the number when removal is unavoidable.
There is a second saving that does not show up on a quote: certainty. Once the hardwood comes up, whatever is under it becomes your problem — old adhesive, a patched section where a wall used to be, a water stain nobody knew about. Floating over a floor that passes the four checks means the week goes the way the schedule said it would.
The Calgary Homes Where This Works Best
The ideal candidate is specific, and there are thousands of them in this city: a home built in the 2000s or 2010s with builder-grade engineered hardwood or a thin solid strip floor on the main level, now scratched up by a decade of dogs, kids and winter grit.
Those floors share three traits that make them good substrates and poor candidates for refinishing. They are flat, because they were installed over a reasonably new subfloor. They are firmly nailed, because that is how they went down. And they have a thin wear layer — often 1 to 2 mm of veneer — which means sanding them is either risky or impossible.
Covering a floor like that is not a compromise. It is the correct answer.
The homes where it works less well are older: 1960s and 70s bungalows across the southwest and northwest, where a 3/4-inch solid oak floor may have twenty years of life left in it and will refinish beautifully. More on that below.
Check 1: Flatness
This is the check that fails most often, and the one with the most forgiving fix.
Rigid-core vinyl is thin — commonly 4 to 6 mm plus an attached pad. It bends over a gentle slope without complaint, but it does not bridge a sharp change. Two things to look for:
Overall flatness. Lay an 8 or 10 foot straightedge across the floor in several directions and look for gaps under it. Manufacturers typically call for 3/16 inch over 10 feet; some allow slightly more. A slow dip across a living room is usually fine. A hump where a joist sits proud is not.
Board-to-board steps. Run a hand across the floor and watch light raking across it from a low angle. Cupped boards — edges higher than centres — create a washboard that telegraphs straight through thin vinyl and, worse, holds the click joints slightly apart. A joint under tension is a joint that separates later.
Minor unevenness gets sanded or filled. Significant cupping means something else is going on, and the cause has to be found before anything is installed over it.
Check 2: Moisture
Cupping is the visible symptom of a moisture problem, but the reading matters more than the look.
Wood that is wetter than its surroundings is still moving. Trap it under a vinyl floor and it keeps moving, slowly flattening or shrinking, and your flat substrate stops being flat. Worse, a floating vinyl floor over damp wood slows the drying the wood was relying on.
Calgary makes this easier than it is in most climates. Indoor humidity here sits low for much of the year — often in the teens to low twenties through a long heating season — so main-floor hardwood is usually dry and stable. The exceptions are specific: a floor above an unfinished or damp crawlspace, a floor that has had a leak at a dishwasher or fridge line, or a floor in a home that ran a humidifier hard without ventilation.
We take moisture readings before installing over wood. If the number is high, we find the source first. Covering it is not a solution.
Check 3 and 4: Solid and Firmly Fastened
These two travel together, and they are where the savings get earned or lost.
Walk the whole floor slowly, in bare feet, in a quiet house. You are listening and feeling for three things:
- Boards that click or flex under weight — a board that has lost its nail.
- Squeaks that move with you — usually the subfloor lifting off a joist and rubbing the nails that hold it, extremely common in Calgary homes over twenty years old as framing lumber dries and shrinks.
- Soft or bouncy areas, which are a structural question rather than a fastener question.
Everything you find gets marked and fixed before the vinyl goes down. Loose boards get re-secured. Squeaky subfloor gets screwed to the joists. Protruding nail heads get set below the surface, because anything proud of the floor becomes a wear point pressing up into the new plank.
Here is the part worth repeating, because it is the single most common regret in this kind of project: a floating floor does not silence a squeak — it seals off the access to it. Once new vinyl is down, the same repair means working from the basement ceiling if there is access, or opening the floor you just paid for. Our subfloor repair page covers the methods, and the difference in cost between doing it now and doing it in two years is not small.
Bounce is a separate conversation. A floor that deflects noticeably under foot traffic has a framing or subfloor issue, and no floor covering fixes it.
The Height Problem Nobody Plans For
The new floor will sit higher than the old one by the thickness of the plank plus its pad — call it 5 to 8 mm for most products. That is not much, and it causes four predictable problems.
Interior doors. They may catch. Trimming a door is routine, and it is cheaper to plan for than to discover.
The top stair riser. This is the one that surprises people. Raise a landing by 6 mm and the top step becomes 6 mm shorter than every step below it. Building code limits how much riser heights may vary within a flight, and beyond the code issue, an inconsistent top step is a genuine trip hazard because people’s feet learn the rhythm of a staircase. Where the new floor meets a staircase, the step has to be built up or the flooring has to be carried onto it. Our stairs installation page covers how that is handled.
Transitions to fixed floors. Where the new vinyl meets tile in an entry or bathroom, or carpet on a stair landing, the height difference has to be bridged with a profile. Most are, easily. The ones that are not get identified at the estimate, not on install day.
Appliances and fixed cabinetry. A dishwasher sits in an opening of fixed height. Raise the floor it stands on and the opening gets shorter. Usually fine, occasionally not.
None of this is difficult. All of it is cheaper to solve before material is ordered.
Floating or Glue-Down Over Wood?
Both work over wood, and the choice is not arbitrary.
Floating click-lock is the default. Fast, reversible, no adhesive, and it tolerates the small seasonal movement of the wood beneath it because the two are not bonded. It needs an expansion gap at every wall and fixed object, covered by baseboard or quarter-round.
Glue-down bonds the vinyl to the substrate. It gives a very solid floor underfoot, handles large open areas and direct sun better, and is common in commercial work. Over existing wood it demands a cleaner, flatter, more stable base — the adhesive transmits every bit of movement in the wood to the vinyl above it. It is also effectively permanent.
For a residential floor over existing hardwood, floating is almost always the right call. Our vinyl flooring page compares the formats in more detail, and the luxury vinyl plank page covers wear layers and core construction.
One practical note on direction: most installers prefer to run the new planks perpendicular to the old hardwood rather than parallel. Running parallel means the new seams can sit directly over the old ones, which concentrates any movement at the same lines.
Cover, Refinish or Remove?
| Route | What you pay for | Best when |
|---|---|---|
| Vinyl over the hardwood | Material, prep, installation, transitions | Thin-veneer engineered wood, or solid wood near its sanding limit |
| Refinish the hardwood | Labour and finish only — no material, no disposal | Solid wood with depth left above the tongue |
| Remove, then install vinyl | Everything above plus $0.50–$3.00 per sq ft tear-out | Wood that is loose, water-damaged, or sitting too high for doors and stairs |
The middle row is the one most homeowners never price. It has no material cost, no removal, no disposal and no height change, which is why it so often wins on a floor that qualifies for it.
When to Refinish Instead
This is the honest counterargument, and it applies more often than homeowners expect.
If the wood under your feet is solid hardwood with enough thickness above the tongue for another sanding, refinishing will almost certainly give you a better floor for a similar or lower cost than covering it. You already own the material. There is no removal, no disposal, no height change, no transition profiles and no stair rebuild — you are paying for labour and finish.
Check the edge of a floor vent or a threshold. If you can see the tongue, or the fasteners sit close to the surface, the floor is near its limit and covering it is reasonable. If there is a good depth of wood above the tongue, price both routes before deciding. Our floor refinishing page explains what the process involves and where a screen-and-recoat is enough.
Covering a refinishable solid hardwood floor with vinyl plank is the one version of this project we actively talk people out of — not because vinyl is a bad floor, but because the alternative is cheaper and the result is better.
Engineered wood with a 1 to 2 mm veneer is the opposite case. It cannot take a full sanding, a screen-and-recoat only renews the surface it already has, and covering it is the sensible move.
What Happens at the Estimate
For a vinyl-over-wood project, the visit is short and specific. We run a straightedge over the floor in several directions and note where it fails. We walk every room listening for squeaks and feeling for loose boards, and mark them. We take moisture readings in the wood and check what is below the floor where there is access. We measure door clearances, the top stair riser and every transition height. And we look at what the existing floor actually is, because a solid hardwood with life left in it changes the recommendation.
You get a written, itemized estimate: material, preparation, installation, transitions and trim on separate lines, valid 30 days, with no deposit at any stage. If refinishing is the better value, that number is on the same page, and you can compare them side by side.
