Why Markham Homeowners Choose ProFlow for Bathroom Renovation 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.
Cross-Connections from DIY Renovations
Markham's active renovation market sometimes leads to improper plumbing connections — like garden hose bibs without backflow preventers or incorrectly vented drain lines. Cross-connections can contaminate your drinking water. We perform cross-connection inspections and install certified backflow prevention devices.
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 Bathroom Renovation Plumbing Process
Consultation and Planning
We review your renovation plans, assess existing plumbing, and create a detailed scope of work. If you're working with a general contractor, we coordinate directly with their schedule.
Rough-In Plumbing
Before drywall goes up, we run new water supply lines, drain and waste pipes, and venting to match the new layout. We pull permits and schedule the rough-in inspection.
Fixture Installation
Once tiling and finishing are complete, we return to install toilets, vanities, faucets, showerheads, and any specialty fixtures. Every connection is pressure-tested for leaks.
Final Inspection and Walkthrough
We complete a final inspection, verify code compliance, and walk you through every fixture. You'll receive documentation for warranty registration and future reference.
