How do I know if I have a hidden pipe leak in my London home?

The clearest sign is usually the water bill. If it jumps without an obvious reason, a hidden leak is worth checking first. Watch for a water meter that keeps moving when every tap in the house is off, a musty smell in one room, or a warm spot on the floor above a hot water line. Older homes in neighbourhoods like Old North and Old South are more prone to this, since their galvanized supply lines corrode from the inside over decades. Call before a drip becomes a soaked subfloor.

What causes pipes to leak in older London homes?

Age and material are the two biggest factors. Galvanized steel supply lines, common in homes built before 1970 across areas like Lambeth and Old South, narrow and weaken from internal corrosion until a pinhole finally gives way. Cast iron drain stacks fail the same way from the inside out. London's moderately hard water adds mineral scale on top of that corrosion, and freeze-thaw cycles stress any pipe running through an uninsulated space. Put those factors together in a 60- or 70-year-old house, and a leak becomes a question of when, not if.

Is a leaking pipe a plumbing emergency?

It depends on what's leaking and how fast. A slow drip under a sink can usually wait for a scheduled appointment. A burst supply line, a wall spraying water, or a puddle near your electrical panel is not something to sit on. Shut off the water at the main valve, move valuables out of the way, and call our 24/7 line right away. We treat active leaks the same as running toilets or sewer backups: urgent calls dispatched immediately, day or night, with no overtime fee for after-hours service.

How We Diagnose and Repair a Leaky Pipe in London, ON

Most calls start with the same question: where is the water actually coming from? Our plumbers use moisture meters, acoustic listening equipment, and video camera inspection to trace a leak without tearing the home apart. A ceiling stain below a bathroom often points to a supply line, not the fixture itself.
Not every leak needs full pipe replacement. A single pinhole in a copper line can often be patched or sleeved. A longer stretch of corroded galvanized pipe, common in London homes built before 1970, usually calls for section replacement with copper or PEX. For damaged drain sections, we sometimes use trenchless pipe lining instead of digging up the yard.
After the repair, we pressure test the line to confirm the leak is gone and check nearby fittings for wear. We clean the work area, haul away old pipe, and explain what we found. Every job carries the Neighbourly Done Right Promise®.

Leaking Pipe Repair for Every Part of Your London Home

Leaking pipe repair looks different depending on where the leak sits in your plumbing system. Supply line leaks put pressurized water behind walls or under floors and can soak insulation within days. Drain pipe leaks move slower but still rot cabinet bases and stain ceilings over time. In older neighbourhoods like Old South, Old North, and Lambeth, we still find galvanized steel supply lines and cast iron drain stacks in homes built between the 1920s and 1970s. Galvanized pipe corrodes from the inside, and London's moderately hard water speeds that process along. Freeze-thaw cycles add another risk, since pipes running through unheated crawl spaces or exterior walls take the brunt of expanding ice. Water heater connections and washing machine supply lines wear out too, usually with a slow drip rather than a sudden failure. Our plumbers carry parts for copper, PEX, and older galvanized systems, so most leaks get fixed on the first visit.
