Leak Detection & Repair Saskatoon — Find It Before It Finds You
Most serious water damage doesn't start with a burst pipe — it starts with a small, hidden leak that goes undetected for weeks or months. Inside walls, under concrete slabs, above ceilings, behind appliances. By the time you see water staining, warped flooring, or mould, the damage is already done. AtlasHC uses a combination of pressure testing, visual inspection, and professional-grade diagnostic tools to locate leaks accurately — without unnecessary demolition — then fix them right.
Whether you've noticed a suspicious wet spot, an unexplained spike in your water bill, or you simply want peace of mind before finishing a basement or buying a home, our licensed plumbers will give you clear answers and a written upfront price before touching anything.
Signs You May Have a Hidden Leak
These are the warning signs Saskatoon homeowners most commonly report before calling us:
Unexplained Water Bill Spike
If your water usage hasn't changed but your bill has climbed, a hidden leak is almost always the cause.
Water Stains or Discolouration
Brown or yellow staining on ceilings, walls, or floors is a classic sign of a slow leak above or behind.
Musty Smell or Mould
Persistent musty odours or visible mould growth in areas that don't get wet from normal use signal a hidden moisture source.
Warped or Buckling Flooring
Hardwood lifting, laminate bubbling, or soft spots in flooring are common signs of moisture from below.
Meter Running with Everything Off
Turn off all water in the house and check your water meter. If it's still moving, you have an active leak somewhere.
Running Water Sounds
Hearing water moving inside walls or under floors when no fixtures are on is a direct sign of a pipe leak.
Our Leak Detection & Repair Process
Precise, minimally invasive, and fully explained at every step:
Initial Assessment
We start with a thorough walkthrough — reviewing symptoms, checking visible plumbing, and testing water pressure throughout the system to narrow down the likely location before any invasive work begins.
Leak Location
Using pressure testing, thermal assessment, and visual inspection techniques, we pinpoint the leak location as accurately as possible — minimising the amount of wall, floor, or ceiling access needed to reach the problem.
Upfront Repair Quote
Once we've located the leak, we give you a clear written price to repair it before any work starts. If there are multiple options — such as a targeted repair vs. a section repipe — we'll explain the trade-offs honestly.
Repair & Verification
We complete the repair, pressure test the system to confirm the leak is fully resolved, and advise on any follow-up steps — including recommendations for drywall or flooring restoration if access was required.

Where We Find Hidden Leaks
- Inside walls — supply lines, elbows, and compression fittings that fail silently
- Under concrete slabs — particularly common in older Saskatoon homes with original copper or galvanized pipe
- Above ceilings — drain lines, supply lines, and wax ring failures from upper floor bathrooms
- Behind appliances — dishwashers, washing machines, fridges with ice makers
- Underground — main water line leaks between the city connection and your home
- Crawl spaces — exposed pipe runs susceptible to freeze damage and corrosion
- Basement mechanical rooms — water heater connections, boiler lines, and pressure valves

Frequently Asked Questions
The quickest DIY check: turn off every water fixture and appliance in your home, then watch your water meter for 15–30 minutes. If the dial or digital display is still moving, you have an active leak somewhere in the system. Other signs include unexplained increases in your water bill, musty smells, water staining, and soft spots in flooring or walls.
Not always — and never more than necessary. We use pressure testing and systematic diagnosis to narrow down the location before any access is made. When access is required, we keep it as targeted and minimal as possible. We'll always explain what's needed and why before we do anything.
Leak detection costs depend on the complexity of the job and how accessible the suspected area is. AtlasHC provides a written upfront quote before any work begins — you'll know the cost before we proceed. In most cases, catching a hidden leak early is far less expensive than the water damage repair it prevents.
Yes. Underground main water line leaks are detected using pressure testing and isolation of sections of the line. Signs of a main line leak include wet patches in the yard, reduced water pressure throughout the home, and a meter that runs continuously even when all interior fixtures are off.
Yes. Many older Saskatoon homes still have original galvanized steel or early copper plumbing that is now 40–60+ years old. These materials corrode from the inside out, and pinhole leaks are common. If your home is older and you're noticing discoloured water, reduced pressure, or any of the warning signs above, a plumbing inspection is worth doing proactively.
