5 Signs You Need an Emergency Plumber in Oakville

Plumbing problems can strike at the worst possible times—late at night, over a holiday weekend, or right before an important family gathering or business opening. When they do, you need to know the difference between a plumbing issue that can wait and one that requires immediate attention from an emergency plumber in Oakville.

Delaying service in a true emergency can lead to water damage, mold growth, structural issues, and expensive repairs. At 17 Plumbing & Construction Design Ltd., we’ve helped hundreds of homeowners and businesses across Oakville and the GTA deal with after-hours plumbing emergencies—quickly, professionally, and affordably.


In this blog, we’ll highlight 5 key signs that it’s time to stop searching “licensed plumbers near me” and pick up the phone for fast, 24/7 help.



1. Water Backing Up Into Sinks, Tubs, or Basement Drains

One of the most obvious signs you need an emergency plumber is when water starts coming back up instead of going down.

If you notice:

  • Dirty water bubbling into your basement drain
  • Sewage rising in your shower or bathtub
  • A strong, unpleasant odor from lower-level fixtures

…you likely have a main sewer line blockage or failure. These types of issues aren’t just inconvenient—they’re serious health hazards and require urgent attention.

We provide sewer line repair services in Oakville, including:

  • Emergency drain snaking
  • High-pressure hydro jetting
  • Camera inspections
  • Trenchless sewer line repair

These tools help us pinpoint the problem fast, whether it’s caused by grease, foreign objects, or tree root intrusion—a common issue in older Oakville neighborhoods.


2. Burst or Leaking Pipes

Pipe bursts don’t always look dramatic—but they can cause thousands of dollars in damage in just minutes. If you notice:

  • Sudden water pooling near the base of walls
  • Wet drywall or bubbling paint
  • Strange hissing or gurgling sounds behind walls
  • A drastic drop in water pressure

…it could indicate a hidden pipe leak or complete rupture. Whether from freezing temperatures or old corroded copper, you need to shut off your water main and call an emergency plumber immediately.

Our licensed team at 17 Plumbing can isolate and repair the leak, and if needed, reroute water lines or upgrade outdated plumbing.


3. Toilet Overflowing or Constantly Backing Up

A single clogged toilet may not feel like an emergency—but if:

  • It happens repeatedly
  • Plunging doesn’t work
  • Multiple toilets or drains back up simultaneously

…you may be facing a more serious mainline blockage or drain vent issue. Overflowing toilets can flood your floors, seep into subflooring, and damage drywall or nearby cabinetry in hours. If you have kids or run a commercial space like a daycare or clinic, this becomes even more urgent.

We often get calls from homeowners who waited too long, and now they need water restoration in addition to plumbing. Don’t wait—our emergency plumbers in Oakville are available 24/7 to fix the problem and prevent additional damage.


4. No Hot Water or Water Heater Failure

Waking up to a cold shower isn’t just annoying—especially in winter—it could be the sign of a failing water heater or plumbing system.

Some warning signs include:

  • Rust-colored water from hot taps
  • Popping or banging sounds from the tank
  • Water pooling around the base of the heater
  • A complete lack of hot water

In homes and businesses alike, no hot water can bring daily life (or operations) to a halt. Our team of licensed plumbers near you can diagnose and address the issue—whether it’s a failed thermostat, burned-out element, or faulty valve—so you’re not left in the cold.

Note: While we don’t install new water heaters, we do offer reliable diagnostic and repair solutions.


5. Frozen Pipes or Unusual Drop in Water Pressure

During Oakville’s colder months, frozen pipes are a real risk—especially in older homes, poorly insulated basements, or commercial buildings with exposed plumbing.

Signs of freezing:

  • No water flow from one or more taps
  • Pipes covered in frost
  • Odd odors coming from drains
  • Sudden low pressure in one section of your home

Frozen pipes can expand and burst, leading to major flooding once they thaw. Acting fast can often prevent this. At 17 Plumbing, we have heat tracing tools, thawing systems, and insulation solutions to address frozen lines quickly and safely.


Why It Pays to Call a Licensed Emergency Plumber in Oakville

In moments of stress, it’s tempting to search “handyman near me” or call someone offering a quick fix—but that decision could cost you more in the long run. Only a licensed plumber can:

  • Properly shut off or isolate water lines
  • Handle high-pressure drainage equipment
  • File permits (if needed) for sewer repairs
  • Ensure repairs meet Ontario plumbing code

At 17 Plumbing, our team is licensed, WSIB-insured, and equipped to handle emergencies across:

  • Lakeshore West
  • Bronte
  • Glen Abbey
  • Kerr Village
  • River Oaks and Uptown Core

We respond fast, show up on time, and do the job right—every time.


What to Do in a Plumbing Emergency

Here’s what you should do while waiting for your emergency plumber to arrive:

  1. Shut off the water:
    Use your main shut-off valve if there’s a burst or overflowing issue.
  2. Avoid using other drains or appliances:
    Don’t run the dishwasher, washing machine, or additional faucets if you suspect a mainline issue.
  3. Clear the area:
    Remove belongings or furniture that may be at risk of water damage.
  4. Document the issue:
    Take photos if the damage is severe—especially if insurance may be involved.
  5. Call 17 Plumbing at 647-862-1317
    Our emergency line is always open.
