Everything You Need to Know About Hiring the Best Plumber in Toronto

What Makes a Plumber Truly the “Best” in Toronto?

Toronto homeowners searching for the best plumber aren’t just looking for someone who can tighten a pipe; they want reliability, speed, transparency, and expertise. And between the different hundreds of plumbing companies operating across the GTA, there are a few things that differentiate between average and exceptional: Licensing, response time, quality of parts, and how a company treats its customers after the job is completed.

All four are our four cornerstones, and that’s what we’ve made our reputation about at BOS Plumbing & Drains. Our plumbers are licensed by the Province, on time, use industry standard materials and guarantee the workmanship of each of their jobs. We’re not just a company that shows up, we’re a company that gets it, that’s why we’re the best plumber in Toronto.

Emergency Plumbing in Toronto – When Every Minute Counts

No burst pipe, no sewage backup and no hot water runs according to the schedule for 9 AM. For this reason, BOS Plumbing provides genuine 24 hour emergency plumbing Toronto services in Toronto, Etobicoke, North York, Vaughan and Brampton. If you call us during an emergency, we will do the following: 

  • A live dispatcher answers immediately — no voicemail, no bots
  • A licensed plumber is dispatched to your address right away
  • You receive a real-time ETA and status updates en route
  • The issue is diagnosed, quoted, and resolved often in a single visit

Our Emergency Response team has the ability to operate throughout the GTA quickly and accurately, from Etobicoke basements to North York condos and Brampton family homes.

Signs You Need An Emergency Plumber

Plumbing issues don’t make themselves known. Then one minute it’s fine, and the next minute water is falling out the ceiling or sewage is backing up through the basement floor drain.

This is exacerbated by the older housing stock in Toronto. Pipes that date from the 1950s don’t fail over time. They fail fast.

If you observe any of these, please contact us on the spot: 

  • Sudden loss of water pressure across the whole house
  • Burst pipes or visible flooding anywhere on the property
  • Sewage backup or a strong sewer smell coming from drains
  • A toilet that won’t stop overflowing
  • Water heater leaking or completely dead
  • Water coming up through floor drains during or after heavy rain

Drain Cleaning & Sewer Services in Toronto

A slow drainage problem is one of the most prevalent and least addressed plumbing problems among Toronto residences. If left unaddressed, a partial blockage can transform into a complete blockage, sewage backup and even structural damage. BOS Plumbing employs professional hydro jetting, drain cleaning and camera inspection technology to find and unclog blockages, rather than just covering up the symptoms.

Our sewer service goes beyond. In older Toronto neighborhoods, where infrastructure is aging, we take care of your homes with full sewer line replacement, main drain repair, installation of back water valves, and French drain systems to protect your home from flooding and sewage intrusion.

Drain Cleaning, Drain Repair And Clog Services In Toronto

One of the most disruptive plumbing problems that a Toronto homeowner can experience is a blocked drain. When left to their own devices, a drain clog gets from a slow-draining sink to a sewage backup in no time at all. BOS Plumbing offers Toronto and the GTA residents the best drain cleaning and drain repair solutions to eliminate the issue and keep the drain pipes safe and sound from further damage.

Drain Clog Repair And Drain Unclog Services: The plumbers employ professional snaking and high-pressure hydro jetting to clear drain clog in kitchen drains, bathroom drains, laundry lines, floor drains and sewer main lines. Over time, chemical drain cleaners deteriorate your drain pipes. We are effective, safe for pipes and leave no residues.

Drain Repair In Toronto: Cracked, corroded, offset or root-invaded drain pipes require more than a snake for repair. A camera inspection is conducted first to give us a clear idea of what’s going on, and once we have, we can make a targeted drain repair from issues that can be fixed right on the spot to a full drain line replacement if the damage is severe. Whether it’s a blocked bathroom drain or a broken main sewer lateral, our drain cleaning service Toronto homeowners used for clients throughout the city.

Drain Line Installation: New/finished basement, additions, or new construction may require new runs of drain pipe. We plan, design and install drain pipes in compliance with the building code of Ontario to ensure proper drainage and long-term operation.

Hydro Jetting: Use hydro jetting if there is a significant amount of grease buildup, mineral scale, or debris that is stuck very deep that snaking is not effective at removing. A high pressure water jet washes the inside walls of the drain pipe, allowing for maximum flow. It’s particularly effective in older Toronto plumbing drainage systems and commercial plumbing kitchen areas.

Drain Snaking: When the blockage is due to hair, grease or small debris, the cost is relatively low, and it is done in just one visit, it’s a quick and effective cleaning solution. The plumber in our Toronto Ontario has professional tools that are capable of going much deeper into pipes than tools at a hardware store. 

Sump Pump Installation, Repair And Replacement In Toronto

Having a sump pump that works is the first line of defense against flooding the basement. Etobicoke and other mature neighbourhoods in Toronto, particularly in waterfront areas or low areas, are susceptible to spring snowmelt and events of significant rain that cause the water to move more rapidly than the drainage systems can handle. Your sump pump is used all year round to prevent basement flooding, so it’s essential for its proper sump pump installation, repair sump pump, and complete replacement by BOS Plumbing.

Sump Pump Installation: When installing a new sump pump or replacing an old one, we will size the sump pump based on the true water level in your basement, install the sump pump and/or expand the sump pit, discharge the water to a safe distance from the foundation and test the system before we leave. Pedestal pumps and submersible pumps, as well as battery backup pumps, are also installed which will continue to pump during a power outage when you need it the most.

Sump Pump Repair: If a sump pump has a constant run time, grinds or rattles, short cycles or it fails to start when the water level rises, it will not fix itself. The technicians can easily diagnose your unit and will let you know if you need replacing the float switch, clearing the intake screen, replacing check valve, or if you need to replace the entire unit. The majority of sump pump repairs can be completed during one visit. Parts are available for all leading brands of pumps. 

Backwater Valve Installation: A backwater valve is a one-way valve installed on your main drain line that physically blocks sewage from flowing back into your home when the municipal sewer system gets overwhelmed during a storm. It’s one of the best flood protection investments a Toronto homeowner can make, and many municipalities offer substantial rebates on qualifying installations. BOS Plumbing installs CSA-approved backwater valves to full Ontario building code standards, and we’ll walk you through the rebate process so you don’t leave money on the table.

Sewage Pump And French Drain Installation: When plumbing sits below grade or yard drainage isn’t moving water fast enough, we install sewage pumps and French drain systems to redirect water away from your foundation before it becomes a basement problem.

Plumbing Repair And Maintenance Services In Toronto

Small plumbing problems have a way of turning into expensive ones when they sit. Consistent maintenance is how you avoid the 2 AM emergency call and the four-figure repair bill that comes with it.

BOS Plumbing offers scheduled plumbing repair and maintenance for both residential and commercial plumbing clients across Toronto and the GTA. Our maintenance visits cover pipe inspections, water pressure testing, fixture assessments, drain flow checks, water heater servicing, and full system reviews for older properties with aging infrastructure.

For Toronto homeowners dealing with pre-1970s plumbing, a scheduled annual inspection catches the early signs of pipe corrosion, root intrusion, and scale buildup before any of them become a plumbing emergency. For commercial clients, our scheduled maintenance plans reduce the chance of a disruption that costs you a full business day.

Plumbing Challenges Toronto Homes Face

Toronto’s plumbing has a history problem. Large parts of the city sit on infrastructure that’s 50 to 80 years old, and aging clay or cast iron drain pipes weren’t built for today’s water demand or tree canopy.

Root intrusion is a real issue in established neighbourhoods like Leslieville, The Beaches, and Roncesvalles, where mature trees have had decades to work their way into old drain lines. In East York and Scarborough, corroded sewer laterals are responsible for a big chunk of the backup calls we get.

Hard water is another factor. Mineral scale builds up inside drain pipes and on fixtures over time, dropping water pressure and shortening the life of water heaters and appliances. And every January, we get a wave of plumber for frozen pipes calls from homes where the insulation around exposed lines just doesn’t hold up.

Common plumbing challenges across Toronto:

  • Aging clay and cast iron drain pipes in pre-1980s homes
  • Tree root intrusion blocking sewer laterals in older neighbourhoods
  • Hard water scale reducing pressure and damaging appliances
  • Frozen pipes in poorly insulated crawl spaces and exterior walls
  • Basement flooding from storm surges and overwhelmed municipal sewers
  • Permit and inspection requirements for major drain or sewer work

By neighbourhood:

  • The Beaches and Leslieville: Root intrusion and cracked sewer laterals from old clay pipe systems
  • East York and Scarborough: Corroded cast iron drains and aging municipal connections
  • North York and Willowdale: Hard water buildup affecting fixtures and water heaters
  • Etobicoke: Foundation waterproofing gaps and frequent sump pump overload during spring melt

Vaughan and new builds: Drainage design issues and warranty-period pipe failures

Every call is different. But the problems we see most often in Toronto homes are predictable enough that our trucks come stocked for them. As a full-service plumbing company trusted across the city, here’s what we handle on the residential side:

Every call is different. But the problems we see most often in Toronto homes are predictable enough that our trucks come stocked for them. As a full-service plumbing company trusted across the city, here’s what we handle on the residential side:

  1. Toilet Installation And Replacement: A toilet installation that runs constantly, cracks, or won’t flush properly is wasting water every day. We install all brands and models including low-flow and dual-flush units, and replace aging toilets completely when repair stops making sense.
  2. Bathroom Fixtures: Faucets, showerheads, bathtub drains, shut-off valves, sink assemblies. If it’s leaking, corroded, or outdated, we replace it cleanly. No drips, no loose connections left behind.
  3. Kitchen Sink Drain Services: A slow kitchen sink drain usually means a partial clog deeper in the drain line. We clear it with professional snaking and hydro jetting, and repair or replace any deteriorated drain pipes and p-traps while we’re in there.
  4. Bathroom Drain Cleaning And Repair: Most blocked bathroom drains in Toronto homes are caused by hair, soap scum and mineral buildup. We do more than push the blockage down; we can clear the bathroom drain sink, tub and shower drain completely. We use a camera inspection for drains which repeatedly fail.
  5. Plumber For Frozen Pipes: Ontario winters are a harsh treatment on exposed plumbing. The damage to a pipe from freezing and cracking is when it thaws. When they get frozen pipes, Toronto homeowners call BOS Plumbing for the services they need. Frozen lines are safely thawed, any splits are fixed and pipes that are susceptible to freezing are insulated to prevent the issue from happening again in February.
  6. Leak Detection: Damaged mold and walls can be caused by leaks, which can be hidden for many months under floors, in walls and above ceilings until people notice them. Our leak detection service utilizes non-invasive diagnostic tools to accurately pinpoint the source of the leak, so the repair is as targeted as possible, and the impact on your home is minimized.
