Parquet Floor Repair
Loose, Lifting & Damaged Blocks (2026)

The common parquet problems

The last row matters. A floor that simply looks tired needs refinishing, not repair, and the parquet sanding and refinishing guide covers that job. This page is about the blocks themselves.

Find the cause before touching the blocks

A parquet block does not come loose on its own. The sanding guide's advice on damp and pests applies to every repair: dark patches, blocks that have cupped or lifted, a musty smell and white salts at the edges all suggest water from below or from a leak nearby, and soft spots, powder, hollow-sounding blocks and small holes suggest termites or beetles. Re-gluing blocks over a damp slab, or over a live termite colony, wastes the repair.

The timber floor moisture guide explains how the shape of the damage points to the source and which simple tests can be run before anyone quotes. If termites are suspected, have the treatment done first; the termite treatment guide explains the inspection and the options.

Loose and hollow blocks: re-gluing

A single loose block, or a small group of them, is the most common parquet repair and usually the simplest:

1. Mark every loose block by tapping the floor; hollow blocks sound different from firm ones.
2. Lift the loose blocks carefully so their tongues and grooves are not broken.
3. Scrape the old adhesive off the slab and the back of each block, and check the slab is dry and sound.
4. Re-fix each block with a flooring adhesive suited to timber and to the subfloor, pressing it level with its neighbours.
5. Keep weight on the area until the adhesive has set, then fill the joints and refinish the patch.

Old parquet in older Klang Valley homes was often laid on adhesives that have hardened and lost their grip over decades. If loose blocks keep appearing across the whole floor, the adhesive has failed generally, and patching block by block becomes a losing game.

A patch lifting into a hump

Timber moves with the humidity. When a parquet floor is laid tight to the walls with no expansion gap, or takes up moisture from a slab or a leak, the blocks push against each other and a section lifts off the slab into a hump. Pressing it back down does not work: the pressure is still there.

The repair is to lift the humped area, let it and the slab dry, deal with any moisture source, trim or re-lay the blocks with a proper gap at the edges, and cover that gap with skirting. The skirting options guide explains why a timber floor must not be pinned at the edge and how skirting hides the gap.

Replacing damaged blocks and matching them

Blocks that are cracked, rotten from water or eaten by termites have to come out. The hard part is finding replacements that match in species, size, colour and age. The sanding guide's practical answer is to take matching timber, ideally reclaimed from a hidden area such as under a built-in wardrobe or cabinet. New blocks can then go into that hidden spot, where the difference will not show.

New timber of the same species will still look lighter or redder at first, because old parquet has darkened with age and finish. That is why a block repair is usually followed by sanding and refinishing at least the affected room, so the new and old blocks are finished together.

Gaps between blocks

Small gaps are normal in a timber floor and open and close with the seasons. Wider gaps, where dirt collects and edges catch, are filled before the floor is refinished. The sanding guide lists gap filling as one of the repairs done before sanding, so the finished floor is smooth and dirt does not collect.

If gaps appear suddenly in one area, look for a reason: a new aircon blowing straight at the floor, strong afternoon sun through a glass door, or a change in how the room is ventilated.

Spot repair, sand the room, or replace the floor?

The sanding guide explains how much sanding a solid parquet floor can take over its life, and the parquet flooring cost guide prices a new floor if replacement makes more sense.

What parquet repair costs

Block repairs are usually quoted after the floor has been seen, because the number of loose or damaged blocks and whether matching timber is available decide the time. These are the related ClickBina figures (indicative 2026, Klang Valley):

Where the floor is part of a wider refresh, the renovation services page explains how flooring, skirting, painting and any leak repair are sequenced as one job.

Keeping parquet from coming loose again

• Wipe spills at once and never wet-mop a timber floor.
• Keep the edges free: skirting over the expansion gap, not boards or furniture jammed against the wall.
• Use felt pads under furniture and mats at doors to stop grit scratching the finish.
• Keep an eye on wet-area thresholds: the bathroom door, the kitchen and any balcony door.
• Refinish before the finish wears through, so water does not reach bare timber.
