We manufacture the flooring; someone else fits it. That split is where most floor complaints actually start. A licensed click floor is engineered to be forgiving, but it still sits on whatever the installer left underneath it, snapped together however carefully the installer worked. Give the same box of premium SPC to a careful fitter and a rushed one, and you get two different floors. Here is what separates the two.
SPC is a floating floor. It is not glued or nailed down; the planks lock edge to edge and rest as one connected sheet across the room. That design is what makes it fast and reversible, and it is also exactly why the surface underneath and the joints between boards decide how the floor behaves for the next decade.
What good workmanship actually looks like
None of the steps below are glamorous. Skipping any one of them is the most common reason a good product ends up looking like a bad one.
- Subfloor prep and levelling: the base is swept clean, dry, and flat to tolerance. High spots are ground down and dips are filled before a single plank goes down. A floating click floor is only ever as good as the subfloor under it.
- Acclimation: boxes sit in the actual room, unopened, long enough to settle to the room's temperature before laying. A fitter who lays straight off the delivery truck is gambling.
- Expansion gaps: a clean perimeter gap around every wall, pipe and threshold so the floor can move with temperature. Skirting or trim hides it later.
- Layout planning: the fitter measures the room, plans plank direction, and checks the final row will not end on a sliver. Staggered end joints, not a stair-step pattern.
- Clean cutting: straight, accurate cuts at walls, doorways and pipes so boards sit tight without being forced.
- Seating the joint: every click is fully engaged along its whole length, tapped home with the right block, checked by feel and eye. A joint that is 'nearly' closed is an open joint.
What poor workmanship causes
Floor failures rarely come from the plank. They come from a step that got skipped, and each skipped step has a signature you can point to.
| Symptom | What it looks like | Usual workmanship cause |
|---|---|---|
| Peaking | Joints lift into a ridge; boards tent up | No expansion gap, or planks pinned tight under skirting |
| Gaps | Seams open up between boards over time | Joints never fully seated, or floor laid before acclimation |
| Hollow spots | A drummy, echoing sound underfoot | Debris or an unlevelled dip left under the floor |
| Lifting / movement | Boards shift or the floor feels loose | Dirty or uneven subfloor; joints not locked home |
Every one of these is preventable on the day of installation. None of them is a fault of the board itself, which is why the fitter matters as much as the spec sheet.
The takeaway for buyers
When you buy SPC, you are buying half of the finished floor. The other half is the workmanship. Follow the product's installation guidance for the exact figures — gap size, acclimation time, subfloor tolerance — and hold your installer to them.

How to choose an installer, not just a price
Most people collect three quotes and take the middle one. A better filter is the questions the installer asks you. A good fitter wants to know about the subfloor, asks whether the planks have acclimated, mentions expansion gaps and thresholds before you do, and walks the room with a level or straightedge before quoting. One who quotes per square metre over the phone without seeing the site is pricing a different, easier job than the one your floor actually needs. Ask to see photos of previous click-floor work, ask specifically about SPC experience, and treat the quality of the survey as a preview of the quality of the work.
The pre-installation checklist worth insisting on
Ten minutes of checks before the first plank prevents most of the failures we ever hear about.
- Subfloor checked flat with a straightedge, high spots ground and low spots filled
- Subfloor dry, clean and vacuumed, with moisture checked on new screeds
- Planks acclimated in the room at its normal living temperature
- Boxes opened and planks mixed from several boxes for natural shade blending
- Expansion gap spacers on hand and door frames undercut where needed
- Layout planned so cut planks at walls stay a sensible width
None of these steps require special skill. They require someone deciding they matter. If your installer treats this list as fussy, that answer is itself the survey result.
Sequencing with the other trades
On renovations and new builds, when the floor goes in matters as much as how. Flooring is a finish, and finishes go in late: after wet trades, after plastering and painting have dried, after heavy deliveries have stopped rolling through. A floor laid early becomes the site's work platform, collecting grit that scours the surface and impacts no wear layer is rated for. Insist that flooring is one of the last trades in, protect it with breathable board rather than tape-fixed plastic if work continues, and never tape directly onto the plank surface. Sequencing discipline is invisible in the finished photos and decisive in how the floor looks after handover.
Why the instructions outrank experience
Seasoned fitters sometimes trust habit over paperwork, and habits formed on laminate or glue-down vinyl do not all transfer to rigid SPC. Manufacturer instructions encode the product's actual engineering: how the licensed click profile wants to be angled and dropped, what expansion gap the core's movement requires, what underfloor-heating limits apply, when an expansion joint is needed across large areas. MILAT publishes installation guidance for exactly this reason; the Unilin click is designed to be forgiving, but forgiving is not the same as arbitrary. When a floor fails and the method contradicted the instructions, the conversation about responsibility becomes very short. Have the installer read them; it costs nothing.
The handover: what to check before the installer leaves
Walk the finished floor while the fitter is still there. Look along the surface toward the light to catch lipping between planks. Check joints are closed tight with no visible gaps, especially at plank ends. Confirm expansion gaps exist under the skirting or trim at every wall and around pipes, and that trims are fixed to the wall, never through the floor. Step around the room and listen for hollow movement over low spots. Open and close doors over the new height. Five minutes of checking with the installer present converts problems into same-day fixes instead of month-later disputes, and any professional worth hiring will welcome the walk-through.
