If you live in Castle Hill, there’s a fair chance your pool was built in the 1980s or 1990s, when the suburb filled with family homes on generous blocks. Those pools have had a long run. Many are on their second surface, some are on their third, and plenty are now showing exactly what a tired surface looks like: rough patches, stubborn stains and hollow-sounding render.
We’ve spent 17 years on the tools resurfacing pools like these across Greater Sydney. This page is about what we see most often on older Castle Hill pools, and what to do about it. For the wider picture of the area, see our Hills District pool resurfacing page.
What an older Castle Hill pool usually looks like
A pool from that era is typically a concrete shell with a plaster or early aggregate surface, a tiled waterline and concrete or tile coping. After this many seasons, the same handful of problems turn up again and again:
- Worn surface that feels like sandpaper on the steps and the shallow end
- Calcium scale and staining from years of hard-working water chemistry
- Drummy render where an earlier surface has let go of the shell in patches
- Loose or cracked waterline tiles, often with tired grout behind them
- Dated coping that has lifted or chipped around the edges
Is it time for a second or third resurface?
Age alone doesn’t decide it. A well-kept pool can go a long time between resurfaces, and a neglected one can need work early. What we’re looking at is the condition of what’s underneath. If you can see a few signs together, it’s usually time. Our guide to the signs your pool needs resurfacing explains which ones matter and which ones are just a chemistry problem.
When a pool has been resurfaced more than once, the prep matters even more. Old layers can hide hollow patches, and a new finish over unsound render fails with it. We grind back to sound render, sound out the surface and cut out anything that has let go. That’s the difference between a surface that lasts and one you pay for twice.
Straight answer: if your older pool only needs a clean-up or a chemical rebalance, we’ll say so. We won’t quote a resurface you don’t need.
Choosing a finish for an older pool
Many older Castle Hill pools were finished in a plain white or pale plaster. If yours is one of them, a modern finish is a good chance to change the look as well as the durability. The common options are below.
| Finish | Why people choose it for an older pool | Worth knowing |
|---|---|---|
| Pebble | Tough, textured and good at hiding wear | Rougher underfoot than quartz |
| Quartz | Smoother feel and an even colour | Gentler for small children and bare feet |
| Tiled interior | Premium look and easy to keep clean | Grout needs looking after |
Not sure which suits you? Our pebble vs quartz comparison sets the two side by side.
Coping and tiles while the pool is empty
An older pool is usually due for more than the surface. Once it’s drained, we check the waterline tiles and coping. If they’re sound, we leave them alone. If they’re loose or cracked, this is the cheapest moment to replace them, because the access is already there. See pool coping replacement for the options.
Timing your resurface around summer
Pool season opens in November, and the best dates book up first. Some Castle Hill families want to be swimming from the start of the season, others by Christmas, and some are happy to wait until later in summer. Whichever it is, an early inspection gives you the widest choice of dates. You can read more in our guide to the best time to resurface.
