Emergency Drain Cleaning

When sewage backs up into your basement or multiple drains fail at once, you need more than a plunger. We respond fast with professional augers (aka. drain snakes) and drain cameras to clear the blockage and identify the root cause, whether it's actual tree roots, grease buildup, damaged pipe or something else.

Main sewer line blockages are the most urgent. When your waste can't exit your home, it backs up through toilets, showers, and floor drains which can turn into a huge inconvenience and become costly. We contain the mess, clear the line, and prevent contamination from spreading.

Common emergency drain situations:

Foul sewage odours from drains

Sewage backing up through basement drains

Multiple fixtures draining slowly at once

Gurgling toilets when running water elsewhere

Emergency Sewer Line Repairs

A collapsed or severely damaged sewer line creates an immediate health hazard. We use cameras to pinpoint the problem fast, whether it's root intrusion, cracked clay pipes, or complete collapse.

Older Niagara Region homes often have original clay or cast-iron sewer lines that can fail during freeze-thaw cycles or heavy rain. We handle excavation and sewer line repairs to stop sewage from flooding your basement or yard.

We repair:

Backed-up main lines

Collapsed clay sewer lines

Root-damaged pipes

Separated joints in aging systems

Emergency Toilet Repairs

A toilet emergency means water flooding your bathroom, sewage backing up, or no working toilet in a single-bathroom home. We arrive equipped to handle any toilet repairs including overflows, complete blockages, and structural failures.

Critical toilet situations:

  • Toilet overflowing and won't stop
  • Detached or wobbly toilet leaking at the base
  • Complete blockage in your only bathroom
  • Cracked tank flooding the floor

For frozen or burst toilet supply lines (common in winter), we stop the water flow, thaw frozen pipes safely, and replace damaged components.

Emergency Water Leak Repair

Burst pipes, failed supply lines, and hidden leaks cause serious damage fast. We shut off water, contain flooding, and repair the source, whether it's a frozen copper line, corroded galvanized pipe, or failed connection.

High-priority leak situations:

  • Burst pipes flooding rooms
  • Supply lines spraying under pressure
  • Water stains spreading across ceilings
  • Mysterious puddles or unexplained water bills

Niagara homes have different vulnerabilities: copper develops pinhole leaks, galvanized steel corrodes from inside, and even PEX can fail at fittings. We pinpoint and repair water leaks fast using moisture detection and repair them properly.
