How do I repair a damaged laminate plank in my New Brunswick home?

Repairing a damaged laminate plank depends on the type and severity of the damage — minor surface scratches and chips can be fixed with repair kits, while a severely damaged plank needs to be replaced entirely by disassembling the floor back to the damaged piece. The good news is that both approaches are manageable DIY projects for most NB homeowners.

For minor surface scratches, use a laminate floor repair marker or crayon that matches your floor colour. These are available at Kent, Home Depot, and most NB hardware stores for $5-$15. Clean the scratch with a damp cloth, apply the marker or crayon following the wood grain direction, and wipe away excess with a soft cloth. For slightly deeper scratches that catch your fingernail, use a laminate repair paste or putty kit ($10-$20) — apply the coloured putty into the scratch, smooth it level with a plastic scraper, and let it cure for 24 hours before walking on it.

For chips and dents, laminate repair kits with coloured wax sticks work well. Heat the wax stick with the included melting tool (or a low-heat soldering iron), drip the melted wax into the damaged area, and smooth it flush with the surrounding surface using a plastic levelling card before the wax sets. These kits run $15-$30 and include multiple colour sticks so you can blend to match your specific floor shade.

For severely damaged planks — deep gouges, water-swollen edges, cracked surfaces, or planks that have buckled — the entire plank needs to be replaced. With click-lock laminate (the standard in NB installations from the past 15+ years), this means disassembling the floor from the nearest wall back to the damaged plank. Remove the baseboard or quarter-round moulding along the closest wall, then unclick each row of planks, numbering or marking them so they go back in the correct order. Replace the damaged plank with a matching spare (this is why keeping leftover planks from your original installation is so important), then reassemble the rows and reinstall the moulding.

If the damaged plank is in the centre of a large room far from any wall, disassembly back to that point may be impractical. In this case, you can use the "cut-and-replace" method: use a circular saw set to the exact depth of the laminate to cut a rectangle inside the damaged plank (staying 2-3cm from all edges), remove the centre piece, then carefully chisel out the remaining edges. Trim the tongue and groove from the replacement plank's edges, apply a thin bead of wood glue to the joints, drop the new plank into position, and weight it flat while the glue dries. This method is trickier and the repair is not as seamless as a full disassembly, but it works when the alternative is pulling up 30 rows of flooring.

NB-specific consideration: if the plank damage was caused by moisture — swollen edges, warped surface, or white discolouration at the joints — fix the moisture source before replacing the plank. Check for leaks, measure subfloor moisture with a pin meter, and verify that your indoor humidity is in the 35-55% RH range. Replacing a moisture-damaged plank without addressing the cause means the new plank will eventually suffer the same fate, especially during NB's humid summer months.

Keep spare planks stored flat in a climate-controlled area of your NB home. Planks stored in an unheated garage or shed experience the full range of NB's temperature and humidity extremes, which can pre-damage them before you ever need them for a repair.
