Our bathroom ceiling was dripping from an upstairs leak. Richard came the same day, cut only where needed, and repaired a pinhole in a copper pipe with no fuss. Incredible work.

We had a mystery leak soaking the basement carpet. These guys found a cracked cast iron drainpipe hidden behind a finished wall. They fixed it quickly for less than we thought.

What Kind of Pipes Leak — And Where It Happens in Niagara Homes

Different neighbourhoods across St. Catharines, Niagara Falls, and Welland have different plumbing systems — and each comes with its own leak risks. Here’s what we commonly see on the job:

St. Catharines

Copper Pipes: Common in homes throughout Glenridge, Secord Woods, and Port Dalhousie, where aging copper develops pinhole leaks or fails at soldered joints.
Cast Iron Stacks: In older two-storey homes in Merritton and Downtown, we often see cracked or weeping drain stacks behind walls.
PEX Lines: In newer homes across Vansickle and Western Hill, PEX pipes are common but can leak at expansion fittings or burst from freezing if not insulated.

Niagara Falls

Galvanized Steel: Many older homes in Stamford and Chippawa still have these rust-prone lines, which often clog or rupture after decades of wear.
ABS/PVC Drains: Common in homes built post-2000, especially in Mount Carmel and Garner, where joint failures or improper slope can cause slow leaks behind walls or ceilings.
Copper Supply Lines: Running toilets, tub surrounds, and basement ceilings often hide slow copper leaks in homes across Lundy’s Lane area.

Welland

Mix of PEX and Copper: In Dain City and other newer developments, we frequently repair PEX joint leaks and fixture connections.
Old Cast Iron & Galvanized: Homes in Downtown Welland and Cooks Mills often have aging metal piping that leaks inside walls or below slab floors.
Drain Leaks from ABS: Improperly glued or unsupported ABS drain lines are a common culprit in finished basements across newer subdivisions.

No matter the pipe type or where it’s leaking, we’ve repaired it before—and we know how to fix it right the first time.

Water Leak Repair FAQ

Below are some of the most common questions we’ve received from customers across the Niagara Region regarding water leaks in their home.

Look for signs like water stains on ceilings or walls, a musty smell, bubbling paint, or a sudden spike in your water bill. If you hear dripping or running water when no taps are on, that’s also a red flag.

Leaks in Niagara homes are often caused by a combination of aging plumbing materials, temperature swings, and installation issues. In older neighbourhoods like Downtown St. Catharines, Merritton, or Stamford in Niagara Falls, leaks are commonly due to corroded copper, galvanized steel, or cracked cast iron drain lines. In newer areas like Vansickle, Garner, and Dain City, leaks usually stem from PEX fittings, plastic drain joints, or poor sealing around fixtures. Seasonal freezing and thawing can also stress pipes—especially in basements, crawlspaces, or homes with poor insulation. Whether it’s a slow drip or a sudden burst, the root cause usually ties back to pipe material, age, and environmental stress.
