Buying a house with a pool in Perth can be exciting. Visions of summer barbecues, morning laps, and the kids splashing around are all part of the appeal. But a pool is also a significant ongoing commitment, and if you do not know what to look for before buying, you could inherit expensive problems that wipe out any perceived value the pool adds to the property.
Here is a practical guide to what you should check, the questions you should ask, and the hidden costs you need to factor in before committing to a property with a pool.
The Pre-Purchase Pool Inspection
A standard building inspection typically gives the pool only a cursory glance. For a thorough assessment, consider commissioning a dedicated pool inspection. A qualified pool technician will assess the following areas that a building inspector may overlook.
Pool Structure and Surface
Concrete pools. Look for cracks in the shell, especially around skimmer boxes, lights, and the waterline. Hairline cracks may be cosmetic, but structural cracks can indicate ground movement, which is common in Perth’s clay soils. Replastering a pool surface costs $8,000 to $15,000, so significant surface deterioration should factor into your offer.
Fibreglass pools. Check for osmotic blistering (small raised bumps on the surface), fading, and crazing (a network of fine cracks in the gelcoat). Also check for any signs of the shell lifting or shifting, which can happen in Perth’s reactive soils during wet-dry cycles.
Tiled pools. Inspect for loose, cracked, or missing tiles, particularly at the waterline. Re-tiling is expensive, and isolated repairs can be difficult if the original tiles are no longer available.

Equipment Condition
Pool equipment has a finite lifespan, and replacing aging equipment after purchase can be a significant unexpected cost. Ask the seller or agent about the age of the following items, and inspect them where possible:
Pool pump
- Expected lifespan: 8 to 12 years
- Replacement cost: $600 to $1,500
- Listen for unusual noises, check for leaks around the pump seal, and note the brand and model
Salt chlorinator
- Cell lifespan: 3 to 7 years
- Unit lifespan: 7 to 12 years
- Replacement cost: $400 to $800 (cell), $800 to $2,000 (full unit)
- Ask when the cell was last replaced and whether the unit has a service history
Filter
- Sand filter sand lifespan: 5 to 7 years
- Cartridge element lifespan: 1 to 2 years
- Tank lifespan: 15 to 20 years
- Ask when the sand was last changed or the cartridge replaced
Pool heater (if installed)
- Solar system lifespan: 15 to 25 years
- Heat pump lifespan: 10 to 15 years
- Gas heater lifespan: 7 to 12 years
- Check for leaks, corrosion, and operation
Automatic pool cleaner
- Suction cleaner lifespan: 5 to 8 years
- Robotic cleaner lifespan: 3 to 5 years
- Check hoses, wheels, and operation
Plumbing
Underground pool plumbing is difficult and expensive to repair. Look for signs of leaks that may require leak detection including:
- Consistently low water level that cannot be explained by evaporation
- Wet patches or unusually green grass near the pool or equipment
- Air bubbles in the pump basket during operation
- Cracked or deteriorated visible plumbing connections
In Perth’s clay soils, ground movement can stress and crack underground PVC pipes. This is one of the most expensive pool problems to fix, potentially costing $1,000 to $5,000 or more depending on the location and extent of the damage.
Water Quality Assessment
Ask for a comprehensive water test or conduct one yourself. The water quality tells you a lot about how well the pool has been maintained:
| Parameter | Ideal Range | What It Tells You |
|---|---|---|
| Free chlorine | 1-3 ppm | Current sanitation level |
| pH | 7.2-7.6 | Basic chemical management |
| Total alkalinity | 80-120 ppm | Water balance stability |
| Cyanuric acid (stabiliser) | 30-50 ppm | If over 100, pool may need partial drain |
| Calcium hardness | 200-300 ppm | Surface protection management |
| Total dissolved solids | Under 1,500 ppm | If high, pool may need draining |
| Salt (if saltwater) | 4,000-6,000 ppm | Chlorinator operation |
Red flags:
- Stabiliser above 100 ppm suggests the pool has not been professionally maintained. A partial drain will be needed, costing $200 to $400.
- Very high TDS indicates the pool has not been drained in years.
- Green or cloudy water indicates current maintenance issues and potential equipment problems.

Safety Compliance
Pool safety fencing compliance is a legal requirement in Western Australia. Non-compliant fencing is one of the most common issues found during pre-purchase pool inspections.
What to Check
- Fence height (minimum 1,200mm on the outside)
- Gate self-closing and self-latching operation
- Non-climbable zone (900mm clear of objects near fence)
- Gap under fence (no more than 100mm)
- CPR signage (current and displayed)
- Pool registration with the local council
- Doors and windows opening into pool area (must be compliant)
Bringing a non-compliant pool up to standard can cost $1,000 to $5,000 or more, depending on the extent of work required. Factor this into your purchase negotiations if issues are identified.
Pool Registration
All pools in Western Australia must be registered with the local council. Ask the seller to confirm registration. If the pool is not registered, it will need to be registered after purchase, and an inspection will likely be required.
Hidden Costs to Factor In
Many buyers focus on the purchase price without fully appreciating the ongoing costs of pool ownership. Here is a realistic annual cost breakdown for a standard residential pool in Perth:
| Expense | Annual Cost |
|---|---|
| Professional servicing (fortnightly) | $1,560-$2,600 |
| Chemicals (if self-managing) | $400-$700 |
| Electricity (pump, chlorinator) | $400-$800 |
| Water (top-up, evaporation) | $100-$200 |
| Equipment maintenance | $200-$500 |
| Insurance increase | $100-$300 |
| Council registration | Varies |
| Total | $2,760-$5,100 |
One-Off Costs to Budget For
If the pool needs attention after purchase, common one-off costs include:
- Green pool recovery: $350 to $1,000+
- Pump replacement: $600 to $1,500
- Chlorinator cell replacement: $400 to $800
- Filter sand change: $250 to $450
- Fence compliance rectification: $1,000 to $5,000
- Surface replastering (concrete): $8,000 to $15,000
- Tile repairs: $500 to $3,000
Questions to Ask the Seller
- How old is the pool?
- When were the pump, chlorinator, and filter last serviced or replaced?
- Is the pool registered with the local council?
- When was the last safety compliance inspection?
- What is the regular maintenance routine?
- Has the pool ever leaked or required structural repair?
- What type of pool is it (concrete, fibreglass, vinyl)?
- Is there a pool warranty or equipment warranty still in effect?
- How much does pool maintenance cost per month?
- Has the pool surface ever been resurfaced or replastered?
Our Recommendation
Before committing to a property with a pool, invest in a professional pool inspection. It costs a fraction of what post-purchase repairs can amount to, and it gives you the information you need to negotiate fairly or walk away from a money pit.
