LVT Lifting or Peeling at the Edges
Why LVT planks or tiles curl, peel or lift at the joints, and how our fitters diagnose and put it right.
Luxury vinyl tile is one of the most forgiving floors on the market, but it isn't immune to problems. When you start noticing plank edges curling upward, corners peeling back, or a slight ridge where two tiles meet, something in the installation or the environment underneath it has gone wrong.
The good news is that lifting rarely means the whole floor is finished. Most cases trace back to one of a handful of causes, and once we know which one is in play, the repair is usually a targeted job rather than a full replacement.
It's also worth knowing that not every lifted edge is a fitting fault at all — a leak from a nearby appliance, a change to the room's heating pattern, or even a new radiator can shift conditions enough to disturb a floor that had been perfectly stable for years.
What lifting and peeling actually look like
- Plank corners curling upward like a dog-eared page
- A visible gap or ridge along a seam that wasn't there at fitting
- Tiles that click or move underfoot near doorways or windows
- Adhesive smell or tackiness returning around the edges of glue-down LVT
The most common underlying causes
Heat and moisture are the two big culprits. LVT expands and contracts with temperature, so if it was fitted without the manufacturer's expansion gap, or if a room gets unusually hot from direct sun or underfloor heating, the planks push against skirtings and each other until something gives at the weakest joint.
- Missing or too-tight expansion gap around the room's perimeter
- Moisture rising through the subfloor and attacking the adhesive
- Poor-quality or insufficient adhesive on glue-down LVT
- Subfloor debris or dips preventing full contact under the plank
How we diagnose it on site
We start with a moisture meter reading on the subfloor near the affected area, check the perimeter gap against the manufacturer's spec, and lift an affected plank to inspect the adhesive and subfloor surface underneath. This tells us within minutes whether we're dealing with a moisture issue, a fitting tolerance issue, or a bonding failure.
What the fix involves
- Localised: lifting and re-bonding the affected planks with the correct adhesive
- Perimeter issue: trimming back skirting or planks to reinstate the expansion gap
- Moisture issue: treating the subfloor with a damp-proof membrane before refitting
- Widespread lifting: replacing the run of planks back to the nearest clean joint
Table: symptom, likely cause, typical remedy
| Symptom | Likely cause | Typical remedy |
|---|---|---|
| Corners curling near a window | Heat expansion, no gap | Re-cut expansion gap, re-lay affected planks |
| Whole run lifting near a wall | Rising damp in subfloor | DPM treatment then re-lay |
| Random tiles peeling | Weak or old adhesive | Strip and re-bond with correct adhesive |
Preventing it happening again
Once repaired, the fix should hold as long as the root cause has been addressed rather than just the symptom. That's why we always check moisture and expansion allowance before re-laying, not just re-glue and hope.
When a full replank is the right call
If moisture has tracked under a wide area of the floor, or if several separate joints are lifting rather than a single localised patch, patch repairs stop being cost-effective and a full replank of the affected run makes more sense than repeatedly chasing individual tiles.
We'll always be upfront if we think a targeted repair is only going to buy a short delay before the same issue resurfaces elsewhere, rather than carrying out a fix that doesn't address the underlying cause.
Frequently asked questions
- Can lifted LVT be fixed without replacing the whole floor?
- In most cases yes. If the cause is localised, such as a bonding failure or a tight expansion gap, we only need to lift and re-lay the affected planks rather than the whole room.
- Is lifting LVT a sign of a bad original installation?
- Not always. It can also be caused by changes in the room, such as new heating, direct sunlight, or a leak, that weren't present when the floor was originally fitted.
- Will underfloor heating cause this?
- It can if the LVT wasn't rated for underfloor heating or the temperature is set too high. We check the product spec and the heating settings as part of our diagnosis.
- How quickly should I get it looked at?
- Sooner is better. Left unchecked, moisture or debris under a lifted plank can spread to neighbouring tiles and turn a small repair into a larger one.
