24/7 Emergency Plumber Ottawa Homeowners Call First

Plumbing emergencies don't wait for business hours. A burst pipe can flood your home in minutes. A failed sump pump during spring runoff can destroy a finished basement. A sewage backup is both a health hazard and a crisis that needs immediate attention. When you call our emergency plumbing service, you reach a real person who dispatches a licensed Ottawa plumber to your home as quickly as possible.

We respond to major leaks, basement flooding, sewage backups, frozen pipes, and sump pump failures 24 hours a day, 7 days a week, including holidays. Ottawa winters are hard on plumbing. When temperatures drop well below freezing and stay there for days, pipes in unheated crawl spaces, exterior walls, and uninsulated basements are at serious risk. Water expands when it freezes, and that pressure can split even copper and PEX lines.

If a faucet doesn't turn on, or you hear running water behind a wall when everything is turned off, shut off your main water valve if you can and call us immediately. The faster we respond, the less damage your home sustains.

Areas We Serve

Comprehensive Plumbing Solutions for Ottawa's Unique Challenges

Real plumbing service means more than fixing what you can see. It means understanding what caused the problem, how it's likely to develop if left alone, and what the right long-term solution looks like for your home. Our licensed plumbers bring experience with Ottawa's housing stock, from century homes with cast iron stacks to new builds with modern PEX systems, and we tailor our approach to your specific situation.

Drain Cleaning Services in Ottawa

When a drain slows down, most homeowners reach for a bottle of chemical cleaner. That might clear a minor clog temporarily, but it doesn't address what's actually happening inside the pipe. Caustic chemicals can corrode older pipes, and they do nothing to remove the buildup that caused the blockage in the first place. If you have recurring slow drains, gurgling when water flows, foul odors near drains, or multiple fixtures backing up simultaneously, the problem is deeper in your system. Tree roots are one of the most common causes of persistent drain problems in Ottawa. Roots seek moisture, and even a hairline crack in a clay or cast-iron sewer line provides an entry point.

Once inside, they expand, catch debris, and eventually block the entire pipe. Grease buildup is another frequent culprit, especially in kitchen lines. Grease clings to pipe walls, narrows the opening, and traps food particles and soap residue. Over time, the pipe becomes completely blocked. We use camera inspection to see exactly what's happening inside your drain lines. A small waterproof camera travels through the pipe and sends a live video feed back to our technician. We can identify root intrusion, grease accumulation, collapsed sections, offset joints, and corrosion without digging up your yard. Once we know the cause and location, we recommend the most effective solution. Professional jetting scours the buildup from pipe walls. Mechanical snaking clears localized clogs. If the line is damaged, we explain what pipe repair or replacement involves. A camera inspection is not just about finding a clog. It is about understanding why the clog keeps coming back. 

When we run the camera, we are looking for changes in pipe diameter, standing water in sections that should drain clear, root intrusion points, grease coating thickness, and any cracks, offsets, or separations in the joints. In Ottawa homes built before 1960, we often find clay tile sewer laterals with oakum-and-mortar joints that have separated due to ground settlement. Those joints leak, roots grow in, and no amount of snaking will fix the root cause. The camera shows whether you need a one-time cleaning or if the pipe has reached the end of its service life. If the pipe is failing, we explain what replacement entails, how we minimize disruption to your yard, and the required permits and inspections. 

If the pipe is in good condition and the clog is isolated, we clear it, confirm flow with a camera, and provide a realistic estimate of how long the repair will last based on what we see inside the line. If you notice water pooling around basement floor drains after heavy rain, that's often a sign that your main sewer line is partially blocked or that stormwater is overwhelming the system. Don't wait until a full backup causes sewage to enter your basement. Contact us for drain cleaning and camera inspection to identify the issue before it becomes an emergency.

How We Diagnose Persistent Drain Problems in Ottawa Homes

When you call about a recurring clog, we start by asking which fixtures are affected and whether the problem happens during or after heavy use. If only one fixture drains slowly, the blockage is usually in that fixture's branch line. If multiple fixtures back up at once, or if you hear gurgling from a floor drain when you flush an upstairs toilet, the restriction is farther downstream in the main drain or sewer lateral.

We run a camera line through the cleanout to see the inside of the pipe in real time. Tree roots look like white or brown hair-like strands pushing through joints or cracks. Grease shows up as a thick, waxy coating that narrows the pipe opening. A bellied section, where the pipe has settled and holds standing water, shows up as a dip with debris collecting in the low spot. Each of these causes requires a different fix. Roots require mechanical cutting and, in some cases, pipe repair at the entry point. Grease needs jetting to scour the walls clean. A belly may need excavation and re-grading of that section. The camera identifies the fix that best matches your pipe condition, so you are not paying for guesswork.

Leaky Faucet and Toilet Repair in Ottawa

A running toilet wastes hundreds of gallons of water and drives up your utility bill. A toilet that won't flush properly, leaks at the base, or requires multiple flushes is more than an annoyance. It's a sign that internal components are failing or that the wax seal has deteriorated. Our licensed plumbers quickly diagnose toilet problems, replace worn flappers, fill valves, and flush mechanisms, and reseal leaking toilets at the base. A dripping faucet might seem minor, but even a slow drip wastes thousands of gallons over the course of a year. More importantly, a leak often indicates that internal washers, O-rings, or cartridge seals are failing. If left unaddressed, a small leak can worsen and damage cabinets, countertops, and flooring. We repair and replace faucets in kitchens, bathrooms, and utility sinks, and ensure your fixtures are installed correctly to prevent future leaks.

Plumbing Fixture Upgrades and Installations

If you're remodeling a bathroom or kitchen, upgrading to water-efficient fixtures, or replacing outdated plumbing, we install toilets, faucets, sinks, and showers, as well as kitchen plumbing, with attention to code compliance, water efficiency, and long-term reliability. We provide options that balance performance and cost, and we outline the timeline and any additional work required before we start. For commercial properties, we install and maintain grease traps, backflow prevention devices, and commercial kitchen plumbing systems. We understand the code requirements for commercial plumbing in Ottawa and ensure your systems meet health and safety standards.

Frequently Asked Questions About Our Plumber: Ottawa

  • In Ottawa, you typically need a permit for new construction, building drains, backwater valves, or building sewer installations. You do not need a permit to remove a fixture and reinstall it with a new one, or to replace hot water tanks or sump pumps; these are re-installations, not new installations, so they also don’t require a permit. You’ll be told whether a permit is needed, and you can either have us pull the permit for you or guide you through the City of Ottawa’s process. The permit ensures the work meets the Ontario Building Code and gets inspected by a City building inspector at key stages. When your estimate includes work that requires a permit, it covers the permit application, the permit fee, and inspection scheduling.
