About Leak Detection
What a Professional Pool Leak Detection & Pressure Testing Actually Looks Like
Pool leaks are deceptively expensive. A pool losing one inch a week looks like normal evaporation — but in Toronto, normal evaporation is closer to a quarter-inch in cool weather. That extra three-quarter-inch is water washing past your liner, through a fitting, or under your deck — and over a season it adds up to thousands of dollars in city water, wasted chemistry, and undermined hardscape.
Our leak detection service is built around a structured diagnostic process, not guesswork. We verify the loss first (most calls turn out to be evaporation or autofill behaviour, not actual leaks), then narrow the source with visual inspection, dye testing, and pressure testing of suction and return lines where applicable. The output is a written report you can act on — or hand to your renovation contractor for an integrated fix.
Catching a leak early is the difference between a $200 fitting replacement and a $20,000 deck rebuild. If your pool is losing more water than you can explain, this is the call to make.
Seasonal Context
Leak detection is most accurate when the pool is open, full, and at operating temperature. We schedule diagnostics from late spring through early fall; off-season inspections are limited to visual-only assessments unless the system is winterized for testing.
Thorough Service
Structured checklists for opening, closing, and weekly visits — nothing skipped, nothing assumed.
Expert Chemistry
Advanced water analysis and balancing for the safest, clearest swimming experience.
Reliable Scheduling
Punctual arrivals and predictable visit windows. We respect your time as much as your pool.
When You Need This
Signs It's Time to Book Pool Leak Detection & Pressure Testing
If any of these apply to your Toronto-area property, pool leak detection & pressure testing should be on your schedule — not on the back burner.
Water level drops faster than the rest of the season
A noticeable drop visit-over-visit, especially when the autofill is running more than usual, is the most reliable early signal of a real leak.
Chemistry refuses to hold
If sanitizer demand is unusually high or chlorine drops faster than usage explains, fresh water is being introduced — which means water is leaving somewhere.
Soft, wet, or settling spots near the pool
Soggy ground, sinking pavers, or moss growth around the equipment pad and pool perimeter are signs of underground water loss.
Visible cracks or stained fittings
Hairline cracks in concrete shells, stained mortar around tile, or rust streaks below skimmer throats are all worth a structured inspection.
Pre-renovation or pre-purchase
Before resurfacing, retiling, or buying a property with a pool, a leak inspection is cheap insurance against finding the problem after the work is done.

Our Process
The Step-by-Step Pool Leak Detection & Pressure Testing You'll Get
Every visit follows the same structured checklist. Nothing is rushed, nothing is skipped, and you get a written record of exactly what was done.
- 01
Loss verification
We establish a baseline — bucket test, autofill audit, and water-level marking — to confirm actual loss vs. evaporation before any diagnostics begin.
- 02
Visual inspection
Shell, tile line, coping, skimmer throats, light niches, returns, and the equipment pad are inspected for cracks, failed seals, and obvious water paths.
- 03
Equipment-side diagnostics
Most 'pool leaks' are actually equipment-side: failed pump seals, leaking heater header, weeping unions, valves, or filter o-rings. We rule these out before testing the plumbing.
- 04
Pressure testing
Where applicable, suction and return lines are pressure-tested against a calibrated baseline to isolate underground leaks line-by-line.
- 05
Dye and skimmer testing
Suspected shell cracks and skimmer faceplates are dye-tested in still water. Light niches are inspected with the pool circulation off.
- 06
Written findings & next steps
You receive a report with the suspected source, severity, and a recommended repair scope — including which trades to engage and what to expect on cost.

Transparent Pricing
What Actually Affects Your Quote
We don't publish a single flat rate because no honest provider can — pool service pricing is driven by your specific property. Here's exactly what we factor into a pool leak detection & pressure testing quote.
Pool type and size
Concrete, vinyl, and fibreglass shells each require different diagnostic techniques and inspection time.
Equipment complexity
Pools with multiple pumps, heaters, salt cells, automation, and attached spas have more potential equipment-side leak points to rule out.
Plumbing layout
Long underground runs, multiple skimmers, and attached spas extend pressure-testing scope.
Access to lines
Suction-side pressure testing requires access at the equipment pad and the skimmer; layouts that bury access points add time.
Follow-up repairs
Diagnostics are quoted separately from repairs. Once the leak is isolated, we provide a clear repair scope so you can decide on next steps.
Every quote we send is itemized. You see what each line covers, where the cost comes from, and what is optional — so you can compare apples to apples against any other provider.

Leak Detection FAQ
Pool Leak Detection & Pressure Testing Questions, Answered
The questions Toronto homeowners ask us most often about pool leak detection & pressure testing — answered honestly, without the sales spin.
How much water loss is normal for a pool?+
Most GTA pools lose ¼ inch to ½ inch per week to evaporation in moderate summer weather, and slightly more during hot, dry, windy stretches. Sustained loss of more than ½ inch per week — especially without unusual heat — is worth investigating.
Will you find every leak in one visit?+
Most pool leaks are isolated in a single structured diagnostic visit. Complex multi-leak systems (an aging shell with multiple cracks, or a property with both equipment-side and plumbing leaks) may require a second pass. Our process is designed to confirm sources, not just guess at them.
Do you do the leak repair too?+
Yes for most equipment-side and accessible plumbing repairs. Deeper structural work (concrete shell repair, underground plumbing replacement, deck demolition) is coordinated with vetted specialty trades — we provide the diagnostic report so the repair scope is accurate.
Can you tell if a vinyl liner is leaking?+
Yes — vinyl liners are dye-tested at suspected cracks, seams, and fittings (skimmer faceplate, returns, light niche, drain). Liner replacement is usually more cost-effective than patching once the liner is over 10–12 years old.
How urgent is a suspected leak?+
Equipment-side leaks (pump seal, heater, unions) are usually low-urgency cost issues. Underground plumbing leaks and shell cracks can undermine decks, hardscape, and structural anchors over time — those deserve a same-week diagnostic visit before the damage compounds.
