If you're renting or buying a villa with a private pool in Phuket — and a huge proportion of the island's expat housing stock has one — pool maintenance is a non-negotiable part of the budget. Phuket's heat, UV intensity, and humidity create conditions that turn a neglected pool green or cloudy within days, especially in wet season.
The good news is that professional pool service in Phuket is genuinely well-developed, affordable relative to Western equivalents, and easy to arrange once you understand how it works. This guide covers what to expect, what it costs, and what to watch out for.
What Does a Weekly Pool Service in Phuket Include?
A standard pool service visit in Phuket (typically 45–90 minutes) should cover all of the following:
Water Testing and Chemical Adjustment
The pool technician tests pH, chlorine levels, and (for saltwater pools) salt concentration. Phuket's intense UV degrades chlorine faster than in cooler climates, and rain dilutes it further — so chemical adjustment is needed at virtually every visit, not just occasionally. A good technician knows the difference between a pool that just got rained on versus one that has a persistent chemistry problem.
Vacuuming the Pool Floor
Leaves, insects, lizard droppings (yes, really), and fine sediment settle on the pool floor. A manual vacuum head or automatic pool robot removes this. Pools with nearby trees — extremely common on Phuket villa plots — accumulate leaves quickly and may need more frequent floor cleaning.
Brushing Walls and Steps
Algae forms on pool walls and steps in the microscopic spaces between tiles and on grout before it becomes visible. Brushing disrupts this early growth and allows chlorine to work more effectively. This step is often skipped by lazy or rushed technicians — a green pool streak along the steps is the telltale sign.
Skimming the Surface
Catching floating debris — leaves, flowers, insects — before it sinks. Your pool's skimmer basket catches much of this automatically, but it needs to be emptied each visit, along with the pump basket.
Filter Check and Backwash
Sand filters (most common in Phuket) need backwashing every few weeks. Cartridge filters need rinsing or replacing every few months. A good pool tech will check filter pressure and report when backwash or maintenance is needed. This is often where corners get cut — ask your service provider how often they're checking and documenting filter condition.

Why Phuket Pools Need More Attention Than You'd Expect
Wet Season Algae
Between May and October, Phuket gets serious rain — not just showers but extended downpours. Heavy rain dilutes chlorine concentrations dramatically, and the combination of warm water, diluted chemicals, and organic matter (leaf fall, insects, blown-in soil) creates an ideal algae bloom environment. A pool left for 5 days without service after a heavy storm can turn visibly green. Twice-weekly servicing is not an upsell in wet season — it's the minimum.
Sun and UV Degradation
Unstabilised chlorine breaks down rapidly in direct UV. Most pool chemicals used in Phuket include a stabiliser (cyanuric acid) to slow this — your service provider should be using stabilised chlorine products or adding cyanuric acid separately. If your pool loses chlorine levels between services even in dry season, check stabiliser levels.
Saltwater vs Chlorine Pools
Many newer Phuket villa builds (2020 onwards in Bang Tao, Surin, and Laguna developments) have saltwater chlorinator systems rather than traditional chlorine dosing. Saltwater pools feel softer and less harsh on eyes and skin, and generate chlorine continuously at lower concentrations. Monthly service cost is similar — the difference is in the equipment maintenance (salt cells need cleaning every 3–6 months and replacement every 3–5 years).
Overflow and Infinity Pools
Infinity pools (very common in sea-view villas in Kamala, Surin, and on the Nai Thon/Bang Tao hillsides) have a more complex water circulation system. They're also exposed to more wind and spray than inground pools with raised walls. Expect to pay 30–50% more for monthly service on an infinity pool compared to a standard plunge or lap pool of similar volume.

Your Estate Management Office
If you're in a managed villa estate in Bang Tao, Laguna, Rawai, or Kamala, your estate management company either provides pool service directly or maintains a list of approved contractors. This is the easiest starting point. Estate-approved contractors know the local water chemistry and have a track record on similar pool types.
Neighbours and Facebook Groups
Ask in "Phuket Expats", "Bang Tao & Laguna Expats", or "Rawai Expat Community" Facebook groups — pool service is one of the most frequently requested recommendations. Real referrals from people with similar pool types in the same area are the most reliable guide. If three people independently recommend the same team, they're probably good.
What to Ask Before Hiring
Before agreeing to a pool service contract in Phuket, ask: How often do you visit? Are chemicals included? Do you leave a service record with chemical readings each visit? What is your emergency response time for a green pool? Will the same technician come each time? The last question matters more than it sounds — consistent technicians notice when something changes.
Red Flags
No written records of chemical readings. Prices that seem extremely low (below 2,000 THB/month for twice-weekly service on a standard pool — chemicals can't be included at that rate). Inconsistent scheduling where a different person shows up every time. Companies that don't respond quickly to a green pool call.
Maintaining Your Pool Between Service Visits
Even with professional service twice weekly, there are things you can do yourself to keep your Phuket pool in better shape:
- Empty the skimmer basket every 2–3 days, especially after storms or windy weather
- Keep a small floating chlorine tablet dispenser in the pool between visits
- Don't let kids or dogs get into a pool immediately after a heavy chemical dosing — wait 4–6 hours
- Keep pool surrounds rinsed down after use to reduce organic matter entering the water
- In wet season, check the pool after major rainstorms and message your service team if the water looks cloudy
