Why Markham Homeowners Choose ProFlow for Emergency Plumbing
Every community has unique plumbing characteristics shaped by housing age, soil conditions, and local infrastructure. Our technicians are experienced with the specific challenges that local homeowners face — from the properties in Unionville to the homes in Cathedraltown.
Aging Cast Iron Drain Stacks
Heritage homes in Unionville and Markham Village often have 80–120 year old cast iron drain pipes. Internal rust buildup narrows the pipe diameter, causing chronic slow drains and sewage odours. Our camera inspection reveals the pipe's condition, and trenchless relining can extend its life by 50+ years without tearing into walls.
Local Tip
Unionville's protected heritage district contains some of Markham's oldest homes, many dating to the mid-1800s. These properties often have original cast iron drain stacks that have corroded from the inside out over 100+ years. If you hear gurgling drains or notice slow drainage throughout the house, the cast iron stack may need lining or replacement. We use trenchless pipe lining technology to restore heritage home plumbing without damaging walls or floors.
Every ProFlow technician is licensed through the Technical Standards and Safety Authority and carries full insurance coverage. All work meets or exceeds Ontario Building Code requirements.
Our Emergency Plumbing Process
Call Our 24/7 Line
A live dispatcher answers your call, assesses the severity, and provides immediate guidance — like where to find your main water shut-off valve to limit damage while you wait.
Rapid Dispatch
We send the nearest available plumber. Average arrival time across the GTA is 45 minutes. Active flooding and gas leaks are dispatched with the highest priority.
Stop the Damage
The first goal is always to stop water flow or isolate the hazard. We carry temporary repair materials on every truck so we can halt damage within minutes of arrival.
Permanent Repair and Documentation
Once the immediate crisis is contained, we complete a permanent repair — or schedule one if parts are needed. We photograph all damage and provide detailed reports for your insurance claim.
