Why Leak Detection Matters
Plumbing leaks do not always cause immediate damage, but even slow leaks can affect drywall, flooring, cabinetry, and structural materials over time.
Homeowners often reach out for leak detection when they notice:
- Water appearing somewhere it should not be, on a bedroom floor, along a baseboard, or in a spot with no obvious explanation
- Stains, bubbling, or soft spots in ceilings or drywall
- Reduced water pressure
- A sudden spike in water bills
- Musty or damp smells near walls or floors
- Sounds of running water when all taps are off
Identifying the source early gives you more options and often reduces the repair work required.
Residential Water Leak Detection
Residential water leak detection focuses on locating the source of a leak with minimal disruption. The goal is not guesswork, but clarity.
In Calgary homes, leaks are commonly found:
- Behind walls or ceilings, where slow leaks can go unnoticed for months before staining, soft spots, or odours appear
- Under floors, including beneath tile or hardwood, where moisture builds up out of sight and can cause significant damage before it is detected
- Beneath sinks or inside cabinets, where supply line connections and drain fittings can loosen or corrode gradually without any visible sign from above
- In shower and bathtub plumbing, particularly around valves, drain connections, and tile surrounds, where water finds its way through over time
- Along hot water lines, which can develop slow leaks at fittings or joints that show up as warm spots on floors or unexplained increases in water bills
- Toilets, particularly when the flange or wax seal begins to fail — one of the more common sources we find
- Exterior spigots that were not properly winterized developed cracks over the winter, which only became apparent once the weather warmed up
- Dishwasher connections, which can loosen or fail gradually inside the cabinet without obvious signs
- Refrigerator water lines are often overlooked until moisture appears behind or beneath the unit
Knowing exactly where the issue is allows for targeted repairs rather than unnecessarily opening up large areas.
We also prepare written reports, where an insurer requires a plumber’s assessment of where and how a leak originated.
How We Find Plumbing Leaks
Leak detection combines experience with the right tools. We use a practical, methodical approach based on what you are noticing in your home.
Depending on the situation, leak detection may include:
- Camera inspections inside pipes and drains
- Thermal imaging to locate temperature changes from leaking hot water lines
acoustic listening devices - Pressure testing to identify water loss in the system
All our vans are equipped with thermal imaging cameras, which allow us to spot leaks without needlessly cutting into drywall or finished surfaces.
Once the source is identified, we explain what we found in plain language so you understand what is happening and your options.
Emergency Leak Response
Some leaks cannot wait. A burst pipe or sudden water line failure needs immediate attention, and that is exactly what we are set up to handle.
Our team is available 24/7 for plumbing emergencies in Calgary. When you call, we respond with a fully equipped van and a plumber who can quickly assess the situation, stop the water where needed, and help you understand what happened and what comes next.
The goal in any emergency is the same as in any other visit: clear communication, careful work, and no unnecessary alarm. We focus on containing the problem first, then walking you through the repair plan so you can move forward with confidence.

Proactive Steps That Help Prevent Leaks
The best leak is the one that never happens. A few simple habits and upgrades can go a long way toward protecting your home:
- Insulate exposed pipes in unheated spaces like garages, crawlspaces, and basements. Calgary winters are hard on unprotected pipes, and a frozen or burst pipe is one of the most disruptive plumbing emergencies a homeowner can face.
- Install a pressure-reducing valve if your home’s water pressure runs high. Excessive pressure places unnecessary stress on pipes, fittings, and appliances over time and contributes to leaks that could otherwise be avoided.
- Schedule a routine plumbing inspection once a year, or, at a minimum, use seasonal changes as a prompt to walk through your home and look for anything that seems off. Spring and fall are natural checkpoints for checking under sinks, around appliances, and at visible connections.
- Replace worn shut-off valves, hoses, and connectors before they fail, not after. Older supply lines and fittings have a limited lifespan, and swapping them out proactively is almost always simpler and less disruptive than dealing with the leak they eventually cause.

Local Leak Detection FAQs for Calgary and Area
Find quick answers to common toilet repair questions, from running toilets to flushing issues. If you don’t see what you’re looking for, our team is happy to help
Plumbing leaks are not always obvious. Some early signs include higher water bills, damp or musty odours, warm spots on floors, or hearing running water when nothing is turned on. Sometimes it is simply water appearing somewhere it should not be, with no clear explanation.
If you want to check before calling, there is a simple test you can do at home. Turn off all water-using fixtures and appliances, then head outside and check your water meter. If the leak indicator is spinning or the numbers are still climbing after 15 to 30 minutes, water is moving through your system where it shouldn’t be.
That is a strong sign of a hidden leak and is worth having investigated.
If something feels off, leak detection can help confirm what is going on and point you toward the right next step.
Yes. We regularly perform leak detection in southwest Calgary neighbourhoods, including Palliser, Oakridge, Braeside, Cedarbrae, Woodbine, Woodlands, Lakeview, and nearby areas. Many homes in these communities have plumbing concealed behind finished walls or floors, which makes early detection especially valuable.
In many cases, yes. Leak detection often allows us to narrow down the source without opening up large areas. If access is needed, we explain why and keep it as focused as possible.
A sudden increase in your water bill without a change in usage is a common reason Calgary homeowners book leak detection. While it does not always indicate a leak, it is worth investigating.
Some of the most common leaks we find include slow leaks behind walls, failing connections under sinks, and shower or tub plumbing leaks.
Over time, even small leaks can lead to damage, mould, or higher repair costs. Early detection usually means simpler repairs and less disruption.
It is becoming more common, especially in homes with finished basements or homeowners who travel frequently. We install Flo by Moen systems for Calgary-area homeowners who want added peace of mind.
Toilets are one of the more common and easily overlooked sources of water waste in a home. A toilet can lose a significant amount of water each day due to a slow internal leak without making any obvious noise or showing any visible signs.
A simple test can help. Drop a few drops of food colouring or a leak detection tablet into the tank, not the bowl and wait 20 to 30 minutes without flushing. If colour appears in the bowl on its own, water is leaking through the flapper or flush valve, which usually means the seal is worn and needs to be replaced.
Other signs worth paying attention to include a toilet that runs intermittently on its own, a faint hissing sound from the tank, or a water bill that has crept up without an obvious reason. If you notice any of these, it is worth having someone take a look. The fix is often straightforward, but the waste adds up quickly if it goes unaddressed.
When you’re in a pickle, we’re here to help.
We started giving pickles to customers for a simple reason, when you go over to someone’s house, you bring something with you.

We’re working in people’s homes, not just on plumbing systems, and we never want that to feel cold or transactional. The pickles are a small, neighbourly way to say thanks for having us in, and to leave behind something a little more memorable than the usual magnet or business card.
It’s simple, but it reflects how we like to do things around here: personal, thoughtful, and with a bit of character.
