- Most "bad floors" are good products installed over a bad subfloor or without the gaps they need.
- Peaking, separating joints and hollow spots usually mean no levelling or no expansion gap.
- Caulk instead of trim, and quarter round everywhere, are signs of a rushed finish.
- Many problems can be fixed without replacing the whole floor, if you catch them early.
We get called in to fix other people's installs a lot. Here's what we look for, what usually caused it, and the honest answer on fixing it.
Floating floors (vinyl, laminate, click engineered)
1. Peaking or buckling
Joints lift into a ridge. Usual cause: no expansion gap, the floor pinched under cabinets, door jambs or heavy kitchen islands, or trims nailed through the floor. Fix: often fixable by cutting back the edges to restore the gap.
2. Joints separating or gapping
Usual cause: an uneven subfloor making the joints flex, or damaged click locks. Fix: lift the area, level the subfloor and reinstall. Sometimes the planks can be reused.
3. Bouncy or hollow spots
Usual cause: dips in the subfloor that weren't filled. Fix: lift, level and relay.
4. Clicking or crackling noises
Usual cause: unevenness, debris under the floor, or doubled-up underlay on a product that already had a pad attached. Fix: depends on the cause. Often it's the same fix as #3.
5. Chipped edges
Usual cause: rough tapping during install, or a low-quality core. Fix: replace individual planks (another reason to keep a spare box).
Nail-down and glue-down floors
6. Squeaks
Usual cause: a loose subfloor that wasn't screwed down first, or fasteners missing the joists. Fix: sometimes from below (if accessible) or with specialty screw kits from above.
7. Cupping
Board edges higher than centres. Usual cause: moisture from below, like a crawl space, slab or leak, or humidity. Fix: find the moisture source first. Then the floor often flattens on its own. Sanding too early makes it worse.
8. Glue-down bubbles or lifting
Usual cause: slab moisture, the wrong adhesive, or poor prep. Fix: depends. Moisture problems need to be solved before any repair holds.
The finishing details
9. Caulk instead of trim
Caulk is for gaps of a millimetre or two at paint lines. It isn't for hiding a 1/4" gap where the floor meets a door frame. Door casings should be undercut so the floor slides under.
10. Quarter round everywhere
Not always wrong, but a whole house of it usually means the baseboards weren't removed. More on trim.
11. Short boards and bad layout
Lots of tiny pieces at doorways, end joints lined up in "ladders" or "stair steps," or a thin sliver along a wall that everyone sees. Good layout is planned before the first row goes down.
12. Clunky stairs and transitions
Mismatched stair nosing, transitions that don't sit flat, or big height changes between rooms. These are the details people notice first.
What to do if your floor has problems
- Take photos and note when it started (season matters).
- Find the product name and the lot number (box end or receipt).
- Contact the installer first. Install problems are theirs, not the manufacturer's.
- If the installer's gone, get an independent opinion before you rip anything out. Many problems are partial repairs.

Common questions
Why is my laminate or vinyl floor lifting at the joints?
Usually the floor has no room to expand: it's pinched under cabinets, door frames or trim, or the expansion gap was skipped. An uneven subfloor can also make joints lift. Restoring the gap often fixes peaking.
Why does my new floor sound hollow?
Hollow or bouncy spots usually mean dips in the subfloor that weren't levelled before install. The fix is lifting that area, filling the low spots and relaying.
Is it normal for a new floor to click or crackle?
A little noise as a new floating floor settles can happen, but ongoing clicking usually points to an uneven subfloor, debris underneath or the wrong underlay.
Who is responsible for a bad flooring install?
The installer, for workmanship problems. Manufacturer warranties only cover product defects, and they usually exclude problems caused by installation or the subfloor.
