  • Pool Mosaic & Tile Repairs Cape Town

Tiles come loose at the waterline long before they come loose anywhere else, and once one goes the ones beside it usually follow. Kwik Pools does pool tile and mosaic repair across Cape Town — from a handful of missing waterline tiles to a full border strip relaid.

Why pool tiles come loose

  • The waterline takes the beating

    That band is wet, dry, hot and cold more than any other part of the pool. The bedding behind it eventually gives up.

  • Movement in the shell

    A crack behind the tile line pushes tiles off long before you ever see the crack itself.

  • Failed grout

    Once grout washes out, water gets behind the tile, and the bond goes soon after.

  • Scale and acid damage

    Hard water leaves a deposit at the waterline, and aggressive cleaning to remove it takes the grout with it.

  • Simple age

    A lot of Cape Town pools still carry their original 1970s and 1980s mosaic. It has had a long life.

  • Poor previous repairs

    Tiles bedded onto a dirty or moving substrate come off again, usually within a season.

Worth knowing: if tiles keep lifting in the same spot, the tile is not the problem. Something behind it is moving or leaking, and bedding a new tile onto it just buys a few months. We check what is behind the tile before relaying anything.

Matching tiles on an older pool

This is the part people worry about, and it is a fair worry — exact matches for older mosaic are often discontinued. We deal with it one of three ways, and we tell you upfront which one applies to your pool.

  • Salvage and re-lay

    Where tiles can be lifted intact from a hidden section, we reuse your originals in the visible band.

  • Closest current match

    Modern mosaic that reads correctly against the existing colour and finish.

  • Relay the full band

    A band that matches itself always looks better than a patch that nearly matches.

  • Step and bench tiles

    Often a different size to the waterline band, and worth treating separately.

  • Border and coping tiles

    The edge tiles that take knocks and foot traffic, repaired or replaced as needed.

  • Regrout and seal

    Sometimes the tiles are sound and only the grout has gone. Cheapest fix of the lot.

How we repair pool tiles

We drop the water below the tile band, strip back to a sound substrate, and check for cracks or damp behind the tiles before anything new goes on.

Then it is bedded onto fresh adhesive, spaced to match the existing band, grouted and sealed. Done properly it should outlast the rest of the surface.

  1. We look at what is behind it

    Loose tiles are a symptom. If the substrate is moving or wet, that gets dealt with first.

  2. We agree the tile approach

    Salvage, match or relay the band — you see the options before we start.

  3. We drop the water level

    Usually just below the tile band. A full drain is only needed for bigger work.

  4. We prepare and bed

    Back to sound substrate, fresh adhesive, spaced to line up with the existing tiles.

  5. We grout and seal

    Colour-matched grout, sealed properly so water cannot get behind it again.

Tile and mosaic work we do

  • Loose and missing waterline tiles
  • Pool mosaic repair and replacement
  • Border and coping tile repairs
  • Step and bench tile repairs
  • Full waterline band replacement
  • Regrouting and sealing
  • Scale removal from tiles
  • Tiling after resurfacing
  • Crack repair behind the tile line
  • Broken tile replacement

Tiles and surfaces usually go together

If the plaster is chalking at the same time the tiles are lifting, doing them separately means paying for access twice and living with a mismatch in between.

In that case we quote the tiles alongside resurfacing so the whole pool comes back looking like one job rather than a series of patches.

Pool tile and mosaic repairs across Cape Town

We work the whole metro from our Plattekloof base — the Northern Suburbs, Southern Suburbs, Atlantic Seaboard, City Bowl, South Peninsula, Helderberg, West Coast and the Cape Winelands. If the pool is also losing water, start with pool leak detection.

Questions we get about pool tiles

Can you match my existing pool tiles?

Sometimes exactly, often closely. Older mosaic is frequently discontinued, so we look at salvaging originals from a hidden area, sourcing the nearest current match, or relaying the whole waterline band. You see the options before we start.

Do you have to drain the pool to repair tiles?

For waterline work we normally just drop the level below the tile band. A full drain is only needed when the damage runs deeper or the job is part of a resurfacing.

My tiles keep falling off in the same place. Why?

Something behind them is moving or leaking. Relaying the tile alone will not hold, so we check the substrate and deal with the underlying cause first.

How long does a waterline tile repair take?

A small repair is typically a day plus curing time. A full waterline band depends on the size of the pool and is quoted per job.

Can you remove the white scale line on my tiles?

Usually yes. Calcium scale can be treated, though where it has been aggressively scrubbed before, the grout underneath is often damaged and needs redoing too.
