Why London Homeowners Choose Mr. Rooter Plumbing
London winters are tough on plumbing. Freeze-thaw cycles crack pipes, and many homes in older neighbourhoods like Old South, Old North, and Lambeth still have galvanized or cast-iron pipes that corrode over time. Tree roots can work their way into sewer lines, and hard water can build up sediment in water heaters. These are not inconveniences. They are real risks to your home and your family's comfort. Our London plumbers know these challenges because we work in this community every day. We understand what causes a backup, how to spot hidden water leaks before they damage your walls, and when a repair makes sense versus a replacement. You get upfront pricing before any work begins, so you know exactly what to expect. No overtime charges. No surprises.

Comprehensive Plumbing Services for London Homes and Businesses
Your plumbing system works hard every single day, delivering clean water, removing waste, and keeping your home comfortable and safe. When something goes wrong, you want the issue fixed quickly and correctly. Our licensed, insured plumbers in London, Ontario, handle everything from emergency plumbing repair to planned installations, and we back every job with the Neighbourly Done Right Promise®. Customer satisfaction is not just a goal: it's how we've built our reputation in this community.
We specialize in drain cleaning with professional-grade tools, including hydro jetting, which uses high-pressure water to scour the inside of drain pipes and remove grease, scale, and even light root intrusion without damaging the pipe. This differs from a traditional drain snake, which punches a hole through a clog but often leaves buildup on the pipe walls to clog again. For recurring blockages or in older homes, we recommend a camera inspection first to see exactly what is causing the problem. The camera shows us whether the line has roots, a belly in the pipe, grease buildup, or a collapsed section. Visual confirmation helps you make the right decision rather than guessing and hoping the problem doesn't come back.
We repair and replace water heaters, including traditional tank models and tankless systems, and we help you choose the option that best fits your home's hot water needs. If you are dealing with recurring drain clogs, a toilet that won't flush properly, low water pressure, or water taking forever to heat up, these are signs of underlying issues that a professional plumber can diagnose and resolve before they become expensive emergencies. Our team also handles sewer line repair and replacement, sump pump installation and maintenance, leak repair, pipe repairs, kitchen faucet installation, and plumbing installations for bathrooms and kitchens. For homes with hard water, we also install water softeners and filtration systems to protect your fixtures and improve water quality.
Schedule a time for you. We are available 24/7 for plumbing emergencies. Financing options are available for larger plumbing projects, so you get the plumbing service you need without delay.
How We Diagnose Common London Plumbing Problems
The difference between a quick fix and a lasting solution starts with an accurate diagnosis. When we arrive at your home, the first thing we do is ask questions and gather information. What symptoms have you noticed? When did they start? Have you tried anything already? Those details help us narrow down the cause before we even open a toolbox.
For water leaks, we trace the source and check for secondary damage. A small drip under a sink or a leaky faucet rots cabinet bases and subfloors if the issue has been going on for a while. For a clog, we determine whether the blockage is in a fixture trap, a branch line, or the main drain. If one sink drains slowly, the issue is usually a local clog. If multiple fixtures back up at once, or the lowest drain in the home overflows first, the problem indicates a main line issue. For water heater problems, we check the unit's age, inspect the tank and components, test the system, and look for signs such as rust, leaks, or sediment buildup, which tell us what is failing and why.
In older London homes, we also look at the plumbing materials. Many homes built between the 1920s and 1970s have galvanized steel supply pipes corroding from the inside, reducing water pressure and causing rusty water. Cast iron drain stacks rust at the joints, and you often do not notice the problem until water stains appear on a ceiling or wall. If you are buying or renovating an older home, we run a camera through the drain lines and inspect visible supply piping to help you understand what you are working with. In many situations, a targeted repipe of the worst sections buys you years of reliable service without the cost of a full-house repipe.
there are multiple ways to solve the problem, we walk you through the pros and cons of each so you can choose the option that fits your home and budget.
Protecting Your London Home's Plumbing Through the Seasons
London's climate puts real stress on plumbing systems. Freeze-thaw cycles in winter crack pipes, spring thaws reveal hidden leaks, and summer heat increases water use and puts extra demand on water heaters and sump pumps. A little seasonal attention prevents expensive emergencies.
In the fall, disconnect and drain garden hoses, shut off the water supply to exterior faucets, and insulate any exposed water lines in unheated areas, such as crawl spaces or along exterior walls. If you have a basement bathroom or laundry room on an outside wall, leave cabinet doors open during extreme cold so warm air reaches the pipes. If you are leaving town during winter, the City of London's Water By-law requires property owners to shut off the water supply and drain the plumbing if the home will be left vacant without heat.
In the spring, check for signs of water leaks that may have developed during winter. Look for water stains on ceilings, walls, or basement floors, and listen for dripping sounds. Spring is also a good time to test your sump pump before the rainy season begins. Pour a bucket of water into the sump pit and make sure the pump activates and drains properly. If you notice your sump pump running constantly or not turning on at all, you need professional sump pump installation or repair service.
In the summer, be mindful of what goes down your drains. The City of London warns homeowners about fats, oils, and grease, which solidify in drain lines and cause blockages over time. Let the grease cool, then dispose of it in the garbage, not down the sink. Use a sink strainer to catch food scraps, and avoid flushing anything other than toilet paper and waste, even if the package says flushable.
A practical tip is to test your main water shutoff valve now, before you need the valve in an emergency. Many older gate valves seize up over time, and if you cannot turn the valve when a pipe bursts, you will have a much bigger problem. If your shutoff is stiff or leaking, we replace the valve with a modern ball valve that turns smoothly and seals reliably.
Common Plumbing Mistakes London Homeowners Make
Over the years, we have seen the same preventable problems repeatedly. Here are a few tips to help you save money and stress.
Using chemical drain cleaners on a slow drain is one of the most common mistakes. If the drain is already sluggish, the cleaner hardens into a gel, which makes the clog worse and harder to clear. A professional plumber clears the issue properly the first time without damaging your pipes.
Flushing so-called flushable wipes is another frequent issue. The City of London warns against this. Most wipes do not break down like toilet paper, and they are a leading cause of sewer backups. If the material is not toilet paper, the material does not belong in the toilet.
Ignoring a running toilet or a leaky faucet might seem minor, but a toilet running constantly wastes hundreds of litres of water per day. A dripping kitchen faucet wastes water and can indicate worn washers or valve seats that are failing completely if not addressed. Both issues usually mean a failed component that costs little to replace and can be fixed quickly.
Pouring grease down the drain is a mistake building up over time. Even if you run hot water, grease solidifies over time and creates blockages. The City offers free FOG disposal cups at libraries and EnviroDepots, making proper disposal easy.
Overtightening fittings during DIY repairs can crack pipes or strip threads. Plumbing connections should be snug, not forced. If you are not sure, call a professional rather than risk a leak or a broken fitting.
Skipping backflow prevention devices is another common oversight. If your home has an irrigation system, a boiler, or certain plumbing fixtures, you need a backflow preventer to protect your drinking water from contamination. A licensed London plumber assesses your system and installs the proper protection if required.

Frequently Asked Questions About Plumbing Services in London, Ontario
You deserve clear answers when something in your home isn't working the way it should. Below are common questions we hear from London homeowners, along with straightforward guidance from our experienced plumbers. If you want help with your specific situation, you can contact us anytime.
Yes! We understand plumbing emergencies do not wait for business hours, which is why our emergency plumber team is always available. The key in an emergency is to limit damage while you wait for help. If it's safe, shut off the water at the nearest valve, and stop using fixtures that feed the problem area. A practical tip is to take a quick photo of the leak source and any visible fittings before you wipe things down. This helps your plumber understand what happened and speeds up the diagnosis once we arrive.
If you are not sure who should handle the problem, you are not alone. In London, the City asks residents to report water issues such as a suspected water main break, no water, a leaking water meter, or frozen water service by calling 519-661-4739, which is available 24/7. For wastewater backups, the City's sewer guidance recommends contacting them to inspect the sewer main under the road. If the issue is inside your home, affects your fixtures, or involves leaks, clogs, water heater trouble, sump pump problems, or a blockage in your sanitary lateral, a licensed plumber is the right call. A helpful rule is this: if the problem is on your property or involves your plumbing fixtures, you will usually need a plumber, even if the City helps confirm the main is clear.
In London, the City recommends calling them right away if wastewater is backing up, because City staff inspect the sewer main under the road to confirm whether the blockage is on the City side or on your sanitary lateral. If the problem is in the city's main, the City repairs the issue. If the problem is in your sanitary lateral, you will need a qualified plumber for emergency plumbing repair. A plumbing tip is to avoid running water anywhere in the home during a backup, since even a single shower can push more wastewater into the lowest drain.
In the City of London, the homeowner is financially responsible for the entire sanitary lateral pipe, including the portion from the property line to the City's sanitary sewer main, known as the Private Drain Connection. The City is responsible for the sanitary sewer main located within the roadway. This matters because a blockage outside your foundation walls is still your responsibility to address. A good tip is to request a camera inspection when you have recurring backups. Seeing inside the pipe helps confirm whether you are dealing with roots, grease buildup, a belly in the line, or a collapsed section, so you can fix the cause instead of paying for repeated drain clearings.
If you suspect frozen pipes, the City of London recommends checking multiple cold taps first. If even one cold tap still runs, the issue is in the home's internal plumbing, and a plumber can help you locate and safely thaw the frozen section. If all water service has stopped or you are not sure where the freeze is, the City asks residents to contact the Water Department. Never use an open flame to thaw a pipe. A safe thaw protects your pipes and reduces the risk of a hidden split leaking after the ice melts.
Often, yes. The City of London states a permit is required when you add, remove, or relocate plumbing fixtures such as sinks, tubs, toilets, or showers, and also for plumbing drainage installation, replacement, or repair. The City also notes that replacing a plumbing fixture in the same location generally does not require a permit. If you are planning a renovation, a smart first step is to confirm whether your project changes any drain locations or venting, since those are common triggers for permit requirements. Common code issues we find in older homes include S-traps under sinks that allow sewer gas into the home, missing or undersized vent stacks, and drains that lack proper slope.
Common warning signs include slow-draining water, gurgling sounds, recurring clogs, and unpleasant odours coming from a sink, tub, or floor drain. Gurgling usually means air is being displaced in the line, either because of a partial blockage or a venting issue that prevents proper airflow. If your toilet bubbles when the tub drains, or your basement floor drain backs up during laundry, that indicates the restriction is in the main drain line, not in a single fixture trap.
Repair makes sense when the unit is in good condition and the issue is isolated, such as a failed thermostat, heating element, or a leaking temperature and pressure relief valve that can be replaced. Replacement is usually the better choice when the tank itself is leaking, the heater cannot keep up with normal demand (called poor recovery rate), or you are facing recurring breakdowns. One component most homeowners are not aware of is the anode rod, a sacrificial metal rod inside the tank that corrodes instead of the tank walls. Once the anode rod is fully corroded, the tank starts to rust from the inside, and this is not repairable. If you hear rumbling or popping sounds, it usually means sediment buildup at the bottom of the tank, which insulates the heating element and forces it to work harder. Flushing the tank helps if caught early, but heavy sediment often means the tank is near the end of its service life.
Your final cost depends on what we find, what parts are required, and how much access we have to the problem area, but you should not be left guessing. With Mr. Rooter Plumbing of London ON, you get upfront pricing, which means you see the price before work begins. This approach helps you make decisions with clear information, especially during stressful situations such as leaks or backups.
Maintenance helps you catch small issues before they turn into water damage, backups, or sudden failures. In London, the City calls out fats, oils, grease, and so-called flushable wipes as common contributors to blockages, noting that these problems build over time rather than appearing overnight.
Yes, if you or your contractor plan to dig. Ontario One Call states you must submit a locate request at least 5 business days before you dig; this is legally required. This protects you from hitting buried utility infrastructure, which can cause injuries and costly damage. Don't feel stressed about this step; we'll help you understand the locate process before anyone breaks ground.
You schedule service by calling us or reaching out online, and choosing a time that works for you. If your issue is urgent, such as an active leak, a sewer backup, or no water, tell us what is happening so we can help you take the right first steps while you wait. Mr. Rooter Plumbing of London ON will ensure your plumbing system is back up and running quickly.
