At Plumbing On Site, we understand that plumbing problems come in many forms — from overflowing toilets to sewer line backups and hidden leaks. That’s why we’ve made it easy for you to explore the most common emergency scenarios we handle, all in one place. Tap through the sections below to learn more about how we tackle each issue quickly, cleanly, and professionally — 24/7.
When your toilet won’t flush or starts to back up, it’s often more than a surface clog. We handle deep obstructions, gaskets, or flange issues before they become messy.
Overflowing toilets can lead to water damage and unsanitary conditions. Turn off the water valve and call us — we respond immediately.
A toilet that won’t stop running wastes water and money. It’s usually a worn-out flapper or a misaligned float valve — we fix both fast.
Leaks around the base often indicate wax ring failure or loose bolts. We reseal and tighten everything to restore a clean, leak-free fit.
Toilets that flush slowly might need snaking or deeper line cleaning. We use camera inspections to find the exact cause.
If wastewater is coming up through your drains, it could be a blocked sewer line. We provide emergency snaking and hydro-jetting services.
A foul smell in your home could be from a dry P-trap, venting issues, or a cracked pipe. We investigate thoroughly to eliminate the odour.
Tree roots are a leading cause of underground sewer damage. We detect and remove root blockages, and repair the damaged pipes if needed.
If your basement or bathroom drains emit a rotten smell, it’s likely a sign of a deeper blockage. We provide full diagnostic and deodorizing services.
Cracked or broken sewer pipes can cause long-term damage and odours. We offer trenchless repair or full replacement depending on severity.
Freezing weather or aging pipes can cause splits that lead to flooding. We shut off the supply, repair the pipe, and clean up water damage if needed.
Leaks showing up in your drywall or ceiling often stem from above — we trace the source and handle it before mold takes hold.
Wall stains or dripping noises? We use leak detection tools to find and fix pipe issues hidden behind walls or under floors.
If you notice pooling around your heater, don’t ignore it — pressure buildup or corrosion could lead to failure. We repair or replace on the spot.
Leaks during or after a cycle often come from worn hoses or bad seals. We fix the cause before it damages your kitchen floor or cabinets.
Overflowing washers, broken valves, or loose supply lines can lead to sudden flooding. We respond fast with tools to stop it and repair it.
Whether it’s a broken heater, valve issue, or sediment buildup — we restore your hot water the same day.
When cold taps are dry, it’s often a blocked or frozen line. We fix it at the source and ensure even flow throughout your home.
Weak flow can result from leaks, clogs, or corroded lines. We pinpoint the issue and bring pressure back to normal.
We’re not just plumbers — we’re your neighbours. With deep roots in the community, we deliver dependable service backed by real local experience.
