The price of detecting a leak in a pool varies depending on several factors. There is no single rate; every pool is different. Here we explain what determines the costs and how to assess a serious quote.
Factors that affect the price
When you ask for a quote to locate a leak, the technician assesses:
- Type of pool: Concrete, fibreglass or mosaic tile pools require different tests. In mosaic tile pools, the grout joints can be an additional leak point.
- Number of circuits: A pool with only a skimmer is simpler than one with a skimmer, inlet, sweep, floor drain and overflow. Each circuit requires a pressure test.
- Overflow pool: These have additional circuits (overflow, balancing) that make the inspection more complicated.
- Access and layout: If the filter is far away or buried, or if the pool is large, the time required increases.
- Diver required: If the leak is in the pool shell (structure), an underwater inspection is needed. This usually adds cost for equipment and professional qualification.
- Repair included: If the quote already includes the repair after detection, the price is higher (but it avoids a second visit).
What a serious quote should include
A complete quote usually includes:
- Site visit: The technician sees the pool shell, the circuits, the filter and the access. It is advisable not to give a quote over the phone without seeing the pool.
- Circuit pressure tests: Each circuit is isolated and a pressure drop is observed. This takes time but it is the basis of the diagnosis.
- Written technical report: Afterwards, you receive a document with the location of the leak, the type of damage and the recommended repair options.
- Detail of what is included: The quote specifies whether it covers only detection or also repair, and which technique will be used (resin, pipe replacement, etc.).
If a technician gives you a figure over the phone without seeing the pool, be wary. Every pool is different.
What to watch out for
Some signs that a quote may not be serious:
- Promises without inspection: Be wary of technicians who promise to find the leak without first seeing the pool or carrying out the full tests.
- Price without seeing the pool: It is impossible to quote without a prior visit.
- No written report: If the technician only gives you a verbal diagnosis and does not document it, you have no record of what was found.
- Very low price: It may mean that not all the necessary tests are included.
- Pressure to decide immediately: A good professional gives you time to think.
Quote vs. repair: two different services
Detecting the leak and repairing it are two separate services. The quote may include only the detection (tests, report) without committing to the repair. This lets you get other opinions or other technicians for the repair. If you want to understand detection prices in general, or check pool repair costs specifically, you can read those guides.
Some technicians offer “detection + repair in one visit” at an overall price, which can be convenient.
How the price is set
The price is set after seeing the pool, taking into account the factors above (specialised equipment, a diver if needed). For a specific quote, request a no-obligation quote; the technician will assess your pool after the visit.
How to save on detection
- Do the bucket test first: If the drop matches the bucket's, the loss is explained by evaporation and there is no need to look for a leak. This saves you unnecessary spending.
- Have information ready: When the loss started, how much the level drops per day, and whether it happens only with the pump on or also at rest. This speeds up the diagnosis.
- Ask several technicians for a quote: Compare not on price alone, but on what each quote includes (circuits tested, report, repair).
- Detection and repair together: It avoids two visits if you can authorise the repair after the diagnosis.
Next steps
If your pool is losing water, start by confirming there is a real leak with the bucket test. Then, request a detection quote from a professional who will carry out circuit pressure tests, camera inspection and, if needed, a diver. With the diagnosis in hand, you will know in more detail how much the repair may cost and can decide how to proceed.
