Sun City · Sun City West · Sun City GrandPool Restoration in the Sun Cities
Old pools, done properly. From Glendale, fifteen minutes away.
The Sun Cities have some of the oldest pools in the Valley. Sun City was built between 1960 and 1978, and around 89% of its homes were finished before 1980. Sun City West ran to 1997. Unless a pool has already been resurfaced somewhere along the way, its plaster and waterline tile have been working for decades — and that, far more than anything unusual about the water, is why scale and staining show up so plainly here.
About the water — straight answer
You will read that Sun City has exceptionally hard water. It does not. EPCOR's own 2025 report puts Sun City at 7 to 11 grains per gallon, and Sun City West lower still. For comparison, the City of Phoenix reports 10.1 to 16.2. EPCOR also states plainly that it does not treat for hardness, so the minerals arrive at your pool either way.
So the scale on your tile is real, but it is not because your water is worse than your daughter's in Phoenix. It is because your pool has had twenty, forty, sometimes sixty more years to collect it. That distinction matters, because it changes what the pool actually needs — and we would rather tell you that than sell you a story.
Why it builds up here in the first place
The Arizona Department of Water Resources puts it starkly: an uncovered Arizona pool loses four to six feet of water a year to evaporation — roughly the equivalent of refilling the whole pool annually.
Here is the part that matters. When water evaporates it leaves as pure vapour, so every mineral it carried stays behind — the CDC's pool code says exactly this, that inorganic content is “concentrated as water evaporates.” You then top the pool back up with fresh water carrying fresh minerals. Do that for forty years and the arithmetic does the rest. Warm water compounds it: the USGS notes calcite is over five times less soluble at 50 °C than at 0 °C, so a hot Arizona pool holds calcium in solution far less willingly than a cold one.
That is the whole mechanism. Not bad luck, not bad water — evaporation plus time.
The three communities are not the same
People lump them together. Their pools, and their rules, are different — and knowing which one you are in changes what has to happen before a truck shows up.
Sun City
Built 1960 – 1978about 27,000 homes
The original Del Webb community, opened on New Year's Day 1960. Census figures put roughly 89% of its housing before 1980, which means a pool here has usually had forty years or more of Arizona sun and mineral load on its plaster and tile.
Before work starts: Governed by SCHOA's CC&Rs, but there is no architectural review committee standing between you and pool maintenance work. Permits for anything structural go through Maricopa County rather than a city, because Sun City is unincorporated.
Sun City West
Built 1978 – 199717,741 rooftops
The second community, finished in 1997 when Del Webb handed it over. Newer than Sun City, but the earliest streets are still approaching fifty years old, and about 84% of its homes predate 2000.
Before work starts: There is no single master set of CC&Rs here — the community is a patchwork of separate sub-associations, and which rules apply depends on your street. Also unincorporated, so permits run through Maricopa County.
Sun City Grand
Built 1996 – 20059,550 homes
The newest of the three, inside the city limits of Surprise. Pools here are younger, so the work is more often scale and staining than end-of-life plaster — though the oldest streets are now approaching thirty years.
Before work starts: The strictest of the three: written Architectural Review Committee approval is required before pool work starts, the application asks for your contractor's licence number, and approved work carries a completion deadline. Permits go through the City of Surprise. Build the approval time into your plans — we can help with the paperwork.
What an older pool usually needs
- Waterline tile & scale removal — the band of white calcium that builds where the water sits. Our specialty, and the most common call from these communities. Get a quote →
- Acid wash — for plaster that has stained and dulled over the years rather than simply gone dirty. Get a quote →
- Green-to-clean — for a pool that got away from you, or one at a home that has been empty over the summer. Get a quote →
- Equipment repair & upgrades — decades-old pumps and filters are often the cheapest thing on the property to make efficient. Get a quote →
Questions from Sun City homeowners
How old are most pools in Sun City?
Sun City was built between 1960 and 1978, and Census figures show about 89% of its homes were finished before 1980. Sun City West ran from 1978 to 1997. So unless a pool has already been resurfaced, the plaster and waterline tile in these communities are often several decades old.
Is the water here harder than the rest of the Valley?
No — and anyone telling you otherwise is guessing. EPCOR's 2025 report puts Sun City at 7 to 11 grains per gallon, while the City of Phoenix reports 10.1 to 16.2. It is genuinely hard water that leaves scale, but the reason older Sun City pools show it so plainly is that they have had far longer to accumulate it.
Do I need HOA approval before pool work in Sun City?
It depends which community you are in, and they are not the same. Sun City Grand requires written approval from its Architectural Review Committee before pool work begins. Sun City and Sun City West have no architectural committee for this, though CC&Rs still apply. We will tell you which applies to your address before we start.
Can you supply the paperwork my community asks for?
Yes. Sun City Grand's application asks for the contractor's licence number, and vendor programmes ask for proof of liability insurance. We can provide those documents so you can submit your application without chasing us for them.
How often does pool tile need cleaning?
You will see a lot of confident claims about a fixed interval. In practice there is no published standard, and it depends on your water chemistry, evaporation and whether you run water features. The honest answer is that the trigger is visible scale at the waterline, not a date on the calendar.
Are you actually local to Sun City?
We are based in Glendale, which puts Sun City and Sun City West a short drive away rather than a trip across the Valley. That matters for scheduling, for coming back if something needs a second look, and for the kind of small follow-up jobs a contractor from the far East Valley will not want to make the drive for.
Wondering what your pool actually needs?
Send a photo of the waterline and we will tell you straight — including if it can wait.
