Pool tiles
Why pool tiles lose grout, and what repair involves
Missing grout around a pool is more than a cosmetic problem. Here is why it happens and how a repair is done.

Pool tile repair that stops small problems turning into big ones
Loose waterline tiles, missing grout and white mineral crust are all fixable. We repair the failed areas and make the joints sound again.
Pool tiles live a hard life. They sit in chemically treated water, move with the shell as the temperature changes and take sun all summer. Over time the grout loosens, tiles lose their bond and the waterline collects mineral deposits.
Catching it early matters. Water that gets behind a tile loosens its neighbours, so a single loose tile is usually a sign to look at the surrounding area, not only that one spot.
What this covers
Waterline and step tile repair
Loose and cracked tiles are lifted, the bed is cleaned and tiles are rebonded or replaced.
Pool regrouting
Failed grout is raked out and replaced with a grout suited to constant wet conditions.
Mineral deposit removal
We clean calcium and scale build-up from waterline tiles so the surface and joints can be assessed properly.
Joint resealing
Perimeter and movement joints are re-formed with flexible sealant so water stays out from behind the tiles.
How the job runs
- 1
Inspect the pool
We check the waterline, steps, spa and surround, and mark every loose or failed area.
- 2
Plan the water level
Waterline repairs need the water lowered. We explain how far and why for your type of pool before booking.
- 3
Remove what has failed
Loose tiles and failed grout are taken out and the surface is cleaned back to a sound bed.
- 4
Rebond and regrout
Tiles are set with a pool-suitable adhesive and the joints are grouted and resealed where movement is expected.
- 5
Cure and refill
We give you the cure time for the materials used before the water goes back up and the pool is used.
Why do it this way
- Stops water working behind tiles and loosening more of them
- A cleaner, safer edge for swimmers
- Joints that cope with pool chemistry and movement
- Repairs scoped honestly: we say when a section needs more than a patch
Pool tile repair: common questions
Does the pool need to be emptied?
Usually not fully. Waterline work needs the level lowered below the tiles. Emptying some pool types can cause damage, so we advise on the safest approach for yours before work is booked.
Why do pool tiles keep falling off?
Common causes are failed grout letting water behind the tile, movement in the shell and a poor original bond. Fixing only the visible tile without addressing the cause is why repairs sometimes fail.
Can you repair a few tiles or do I need a full re-tile?
Many pools only need targeted repairs. If the bond is failing across large areas we will tell you, and explain what a bigger job would involve.
How long before the pool can be used again?
That depends on the adhesive, grout and sealant used and on the weather. We give you the cure times for your job before the water is topped up.
