Corroded Drain Pipe Repair in Toronto
We Replace Old, Rusted Cast Iron Drains — Safely and Cleanly
Old cast iron drain pipes were built to last… but not forever. Over time, they corrode from the inside out — leading to leaks, blockages, bad smells, and even pipe collapses. At UPR, we specialize in identifying and replacing corroded drain lines, especially in older Toronto homes.
Whether it’s a small leak or a full replacement, we’ll take care of it with minimal disruption to your home.
Signs of Pipe Corrosion
Persistent drain clogs or backups
Sewer odours near sinks, tubs, or basement drains
Wet spots or puddles under pipes
Flaking, rusty, or discoloured cast iron pipes
Gurgling or bubbling sounds in plumbing
Staining on walls or ceilings near pipe runs
If your home was built before the 1980s, there’s a high chance your drains are cast iron — and overdue for inspection.
