—Renovation and tiling
Signs a pool needs renovating
Routine care keeps water clean. It cannot fix a surface, a seal or a structure that has reached the end of its life.
Pools age. Grout washes out, tiles loosen, plaster roughens and stains, coping cracks, and waterproofing eventually fails. When the same problems return after every clean, or the pool loses water that cannot be explained by evaporation, the issue is usually in the fabric of the pool rather than the water. At that point, renovation is the lasting fix.
Renovation guides cover work on a pool that already exists: its surface, its waterproofing and sometimes its structure.
Renovation may also be driven by appearance or use: a pool that looks dated beside a refurbished villa, steps that no longer suit the family, or lighting and equipment that are inefficient. A survey of the pool’s condition separates what is cosmetic from what is structural and helps decide the scope.
01Summary
What matters most here
Recurring problems
Issues that return despite maintenance.
Unexplained water loss
More than evaporation accounts for.
Surface failure
Loose tiles, washed-out grout, rough plaster.
02Detail
Common signs
Grout loss
Gaps between tiles where grout has washed out, letting water reach the adhesive behind.
Hollow or loose tiles
Tiles that sound hollow when tapped or have detached.
Rough or stained plaster
Surfaces that scratch feet or hold stains that do not clean off.
Cracked coping
Loose or broken edge stones and failed joints.
Water loss
A level that falls faster than evaporation explains.
03Before you start

—In practice
How to use this
Walk round the pool on a bright day and note, with photographs, what you see: washed-out grout, hollow-sounding or missing tiles, rough or stained plaster, rocking coping, cracks, and any water loss that evaporation does not explain. Run a bucket test if loss is suspected. Those notes let a surveyor separate surface wear from a problem in the structure or waterproofing.
Mistakes worth avoiding
- Treating fabric problems as water problems
- Stains that return after every clean, or tiles that keep coming loose, are not solved by chemistry. They point to the surface or what lies behind it.
- Waiting for a tile to fall
- Hollow areas can be found by tapping long before tiles detach. Finding them early keeps the eventual repair smaller.
04FAQ
Common questions about this
- Can maintenance fix loose tiles?
- Not reliably. Loose tiles usually point to failed adhesive or waterproofing behind them.
- How do I know if water loss is a leak?
- A bucket test compares pool loss with evaporation; a bigger loss suggests a leak.
- Is renovation only cosmetic?
- It can be, but often it also restores waterproofing and repairs structure.
- Should I renovate before a leak gets worse?
- Finding the cause early usually limits damage and cost.
