Hidden Plumbing Leaks in Saskatoon: How to Detect and Fix Them
Hidden plumbing leaks in Saskatoon can cause far more damage than most homeowners realize. A slow drip behind the wall might not seem like much, but it can quietly raise your water bills, promote mould growth, and even weaken your home’s structure. Because these leaks often happen out of sight, they usually go unnoticed until significant and expensive damage has already occurred.
In this guide, Boss Plumbing, Saskatoon’s trusted plumbing experts, explain how to detect and fix hidden leaks, what warning signs to look for, and how to prevent future issues before they turn into costly repairs.
Hidden plumbing leaks in Saskatoon waste hundreds of litres of water every month, drive up your utility bills, and can lead to costly property damage. According to the City of Saskatoon’s Water and Sewer Services, even small, unnoticed leaks are among the biggest sources of wasted water.
Saskatoon’s harsh winters make the problem worse. As temperatures drop, pipes expand and contract, increasing the risk of cracks and hidden leaks. Once water seeps behind walls or under floors, it can damage insulation, electrical wiring, and drywall, triggering a chain of costly repairs.
Pro Tip: If your water bill suddenly spikes without any change in usage, chances are you’ve got a hidden leak somewhere in your plumbing system.
What Are the Most Common Signs of Hidden Plumbing Leaks?
You might not see a puddle, but your home often gives small clues that something is wrong. Ask yourself these questions.
Why Are My Water Bills Higher Than Normal?
A sudden spike in your water bill without any change in usage is one of the clearest warning signs of a hidden plumbing leak. Even a small drip can waste hundreds of litres of water over time, adding up to unexpected costs on your monthly bill.
Why Does My Home Smell Musty or Damp?
That persistent musty smell you can’t seem to get rid of usually points to moisture trapped behind walls, under floors, or inside cabinets. Hidden leaks create the perfect environment for mould and mildew to grow, no matter how often you clean.
What Causes Water Stains on My Walls or Ceilings?
Brown or yellow stains on your ceiling or walls are a telltale sign that water is seeping through. In most cases, the source is a leaking pipe or a bathroom fixture located above the affected area.
Why Is My Paint Bubbling or Wallpaper Peeling?
If your paint starts to bubble or your wallpaper begins to peel, trapped moisture is likely to blame. Water from hidden leaks breaks down adhesives and weakens surfaces, causing visible damage over time.
Why Are My Floors or Baseboards Warping?
Mould needs moisture to grow, and hidden leaks provide exactly that. Even in rooms that don’t typically get wet, such as bedrooms or hallways, an unseen leak can create the damp conditions where mould thrives.
Why Is My Water Pressure Suddenly Lower?
When water escapes through a leak before reaching your fixtures, you’ll notice a weaker flow from taps and showers. A sudden drop in pressure could mean a hidden leak somewhere in your plumbing system.

Where Should I Check for Hidden Plumbing Leaks in My Home?
Below are common areas you are likely to detect hidden leaks, which might be small but can be quite damaging.
Location | Why It’s Vulnerable | Inspection Tip |
|---|---|---|
Under sinks | Loose fittings or worn seals | Run water and feel pipes with a dry towel to detect moisture |
Around toilets | Faulty wax seals | Look for water pooling near the base |
Behind showers or tubs | Aging plumbing joints | Check for soft drywall or peeling caulk |
Basement pipes | Rust or cold-weather corrosion | Inspect joints for discoloration or residue |
Ceilings below bathrooms | Supply line leaks | Watch for sagging drywall or stains |
Exterior taps | Freeze-thaw stress | Turn the hose on and check for dripping water outside |
🧰 Quick Tip: Turn off all water in your home, then check your water meter. If the dial still moves, you likely have a hidden leak.
How Can I Detect a Hidden Plumbing Leak Before It Gets Worse?
Catching a hidden plumbing leak early can save you from major water damage and expensive repairs. Here are some of the most effective methods homeowners and plumbing professionals use to spot leaks before they escalate.
What Is the Water Meter Test?
Start by turning off all taps and water-using appliances in your home. Then, check your water meter. If the dial or numbers continue to move after 10–15 minutes, it means water is still flowing somewhere, indicating a hidden leak.
Can I Hear a Leak Through My Walls or Floors?
Yes. When your home is quiet, listen carefully near walls, ceilings, or floors. A faint hissing, dripping, or running-water sound often points to a hidden leak behind your surfaces.
How Do Plumbers Use Moisture Meters and Infrared Cameras?
Professional plumbers use specialized tools like moisture meters and infrared cameras to detect temperature changes caused by water buildup. At Boss Plumbing, we use infrared imaging to locate leaks precisely, without the need to cut into your walls or floors.
What Is the Food Colouring Test?
This quick test helps identify toilet leaks. Add a few drops of food colouring into your toilet tank and wait 10–15 minutes without flushing. If coloured water appears in the bowl, your flapper valve is leaking and should be replaced.
Can My Appliances Cause Hidden Leaks?
YES. Appliances like washing machines, dishwashers, and water heaters can develop slow leaks that go unnoticed. Check underneath and around them for moisture, rust, or condensation. especially during colder months when connections can shift or crack.

How Should I Fix a Hidden Plumbing Leak Safely?
Minor leaks can sometimes be handled with DIY tools, but hidden or recurring leaks should always be inspected by a licensed plumber.
Leak Type | DIY Fix (If Minor) | Professional Solution |
|---|---|---|
Loose pipe under sink | Tighten joint carefully | Replace worn washers or fittings |
Toilet base leak | Replace wax ring | Inspect and reseal the entire fixture |
Pipe behind wall | Shut off water, patch visible area | Camera locate and replace damaged pipe section |
Ceiling leak | Patch and dry area | Identify and fix the hidden line above |
Avoid guessing where the water is coming from. Water often travels along beams and appears far from the actual leak. At Boss Plumbing, we use non-invasive leak detection methods to find the exact source with minimal disruption.
When Should I Call a Professional Plumber for a Leak?
You should contact a plumber if:
- You hear running water when taps are off
- Water stains continue spreading
- A DIY repair doesn’t last
- The leak is near electrical wiring or foundations
Moreover, Saskatoon homes are especially vulnerable during winter. Even a slow leak can freeze and burst overnight. For immediate help, call Boss Plumbing’s Emergency Plumbing Services in Saskatoon, available 24 hours a day.
How Can I Prevent Hidden Plumbing Leaks in the Future?
Regular plumbing maintenance is the most effective way to prevent hidden leaks and protect your Saskatoon home from costly water damage. Here are some proactive steps you can take to keep your plumbing system in top shape year-round.
Why Should I Schedule Annual Plumbing Inspections?
Booking a yearly inspection with a licensed Saskatoon plumber helps identify leaks before they cause damage. During these checkups, your plumber will test water pressure, tighten loose fittings, and inspect pipes for early signs of corrosion or wear.
How Do I Protect Pipes During Saskatoon Winters?
Saskatoon’s freezing temperatures make pipes especially vulnerable. Insulate exposed plumbing with foam sleeves or heat tape, particularly in unheated areas like basements, crawl spaces, and garages, to prevent pipes from freezing and bursting.
How Can I Control My Home’s Water Pressure?
High water pressure might feel convenient, but it puts unnecessary stress on your plumbing. Use a pressure regulator to keep your home’s water pressure below 60 PSI and reduce the risk of leaks or pipe damage over time.
Should I Replace Old Fixtures and Hoses?
Yes. Aging hoses and connections. especially on washing machines and dishwashers, are common sources of hidden leaks. Replace them every five years, or sooner if you notice bulging, rust, or cracks around fittings.
Why Should I Keep Gutters and Downspouts Clear?
Clogged gutters can cause water to pool around your home’s foundation, adding pressure to underground pipes and increasing the risk of leaks. Keep gutters and downspouts clear so rainwater can drain safely away from your property.
