Pool repair: what it costs before anyone quotes you

Pick the symptom, see the GTA planning band, then compare crews who actually do the work. Detection, parts and labour are separate line items — this page shows all three.

Start with the symptom

Heater won't fire or water stays cold

Gas heater, heat pump or control fault. Diagnosis first — most heater calls are not a dead heater.

Diagnostic service call
Often credited against the repair if you approve it the same visit — ask before booking.
$95–$185per visit
Heater repair (ignition, sensor, manifold)
Common faults are a flame sensor, pressure switch or a cracked manifold. Parts included.
$350–$900per repair
Heater replacement
Gas and heat-pump units are priced differently; load sizing and gas line work move the number.
$2,400–$5,500installed

The five figures in a repair quote

Pool repair pricing looks opaque because four or five separate numbers get folded into one sentence. Split them out and the quotes start making sense.

  • Diagnosis: $95–$185 for the visit. Often credited against the repair if you approve it that day.
  • Labour: roughly $100–$200 per hour, more for a two-technician crew or after-hours calls.
  • Parts: usually at list price plus a small margin. Ask whether the part is OEM.
  • Access: deck cutting, draining or a crane charge. This is where a “from” price turns into a real invoice.
  • HST: 13% in Ontario, on top of everything above.

If a quote is a single number with no breakdown, ask for the five lines. A crew that will not itemise a repair is a crew that will surprise you later.

Leaks are priced in two parts

Detection and repair are separate jobs, and the second one is much bigger than the first. A pressure test or sonic listen runs $350–$650 and tells you where the water is going. Finding it under a patio stone is a$900 repair; finding it under a poured concrete deck pushes past$1,500 because the deck has to be cut and patched.

Do the bucket test first. If the pool loses more than 25 mm a day while a bucket of pool water beside it does not, book detection. Losing less than that in July is usually evaporation plus splashing.

Repair or replace

The honest threshold for each part.

A repair that buys one season is not a repair. These are the lines most GTA service managers use when they are not chasing a sale.

PartRepair makes sense
HeaterSensor, pressure switch, ignition or manifold under 8 seasons
PumpCapacitor, seal, impeller or motor under 8 seasons
FilterSand or cartridge change, DE grid set, valve gasket
Vinyl linerOne clean puncture on a liner under 8 seasons
Salt cellCleaning or a scale removal at 3–5 seasons

Before you book

Five questions, and the answer you want.

None of these require technical knowledge. All five change what you pay.

Heater call in July? Say so on the phone. Same-week slots exist, but the crew needs to know it is urgent before they build the route.

  1. 01

    Is the diagnostic fee credited against the repair?

    You want a yes, or a fixed number in writing.

  2. 02

    Will you confirm the leak before cutting anything?

    A pressure test or dive call first — never exploratory deck cutting.

  3. 03

    Is the part new, OEM or a substitute brand?

    Substitute parts are fine if the warranty and price reflect it.

  4. 04

    What does the labour warranty cover?

    At minimum the same fault for 30–90 days.

  5. 05

    What is the not-to-exceed number?

    A ceiling before work starts, so the invoice cannot drift.

Repair FAQ

What homeowners ask first.

Losing water right now? The patch vs replace guide covers liner leaks, and Toronto service pricing covers the seasonal side.

How much does pool repair cost in the GTA?

A minor fix is $150–$400 and major equipment work runs $2,000 or more, with most calls landing between. A diagnostic visit is $95–$185, technician labour is roughly $100–$200 per hour, and parts are extra. Leak detection ($350–$650) and the repair itself ($900–$2,000) are two separate bills.

Do I have to pay for the diagnosis?

Usually yes, $95–$185, and most GTA companies credit it against the repair if you approve the work on the same visit. Ask that question when you book — it is the single easiest thing to confirm before a technician is at your door.

How do I know if I am losing water or it is just evaporation?

Run a bucket test: fill a bucket with pool water, mark the level, set it on the step and leave it 24 hours. If the pool drops faster than the bucket, you have a leak. Normal evaporation is about 3–5 mm a day; more than 25 mm a day is a leak call.

Should I repair or replace a failing heater or pump?

As a rule, repair while the unit is under 8 seasons old and the fault is a sensor, switch or capacitor. Replace when the heat exchanger or motor housing is cracked, or when the repair quote passes half the price of new equipment. A repaired 12-year-old heater usually fails again within two seasons.

Does pool repair need a permit in Ontario?

Not on its own. Repair that changes the pool's footprint, the deck or the fence line can trigger a permit, and the enclosure still has to meet your municipality's rules afterwards. Equipment swaps and plumbing repairs under existing decking do not normally need one.
