Plumbing & Drain Services

Protect your home from sewer backups. We install backwater valves that prevent sewage from reversing into your basement — essential for older GTA homes and required for some municipal rebate programs.

Upgrading your kitchen? We install dishwashers with secure hookups, leak-free drainage connections, and code-compliant supply lines throughout the GTA.

From kitchen sinks to main sewer lines, we clear blockages fast using professional-grade equipment. We diagnose the root cause — not just the symptom. Why root cause diagnosis matters →

Corroded, undersized, or repeatedly blocked drains often need full replacement rather than ongoing clearing. We replace drain lines using durable, modern materials built to code.

Dripping taps, low flow, or an outdated fixture — we repair and replace kitchen and bathroom faucets, fix leaks, and upgrade your fixtures across the GTA.

Hidden leaks can cause thousands in water damage before they're noticed. We use modern detection tools to locate leaks behind walls, under slabs, and in concealed pipe runs — then repair them properly. Why preventative plumbing matters →

We install and repair exterior hose bibs that are properly frost-protected for Ontario winters — preventing costly freeze-and-burst damage each season.

Buying or selling a home? We provide thorough plumbing inspections covering pipe condition, fixture function, water heaters, shut-off valves, and drainage — with a clear written report. Why hiring the right plumber matters →

Finishing a basement or remodeling a bathroom? We handle all rough-in plumbing for sinks, toilets, tubs, showers, and appliances — to code, before walls close. Why early planning matters →

Installing a fridge with a water dispenser or ice maker? We connect refrigerator water supply lines safely and to code — no DIY kits, no slow leaks behind appliances.

From aging clay pipes to tree root intrusion — common throughout GTA neighbourhoods — we clean, repair, and where needed replace sewer lines to restore proper flow.

Diagnose the problem without guesswork. We run high-definition cameras through your drain and sewer lines to pinpoint cracks, root intrusion, collapsed sections, or foreign object blockages before committing to any repair.

Inconsistent temperatures, low pressure, or a shower that won't shut off properly — we repair and replace faulty shower valves in homes and condos across the GTA.

Ontario's spring thaw and heavy rainfall put GTA basements at risk. We install, replace, and service sump pumps to keep your foundation dry — and recommend battery backup systems for added protection.

From a running toilet to a full commercial replacement, we install and repair toilets of all types — including pressure-assist models purpose-built for high-traffic commercial environments.

We supply and install traditional tank and tankless water heaters — gas and electric — across Toronto, the GTA, and surrounding areas. All installations include required permits and disposal of your old unit.

Old galvanized steel pipes are a common source of low pressure, discoloured water, and slow leaks in GTA homes built before the 1970s. We replace aging supply lines with modern, durable materials.

Whether it's a lodged object, a blocked S-trap, or a deeper drain obstruction, we clear clogged toilets using commercial-grade augers — and investigate further if the issue extends beyond the fixture.

Grease and food accumulation in kitchen drain pipes is one of the most common plumbing issues in the GTA. We clear the full buildup and offer a mini hydro jet scrub to prevent quick recurrence.

Hair, soap, toothpaste, and bathroom products accumulate into stubborn clogs over time. We clear bathroom sink drains thoroughly — including popup stoppers and deeper pipe sections if needed.

Hair and soap buildup in shower and tub drains can be tricky to reach without the right tools. We clear most blocked shower drains through the overflow — minimizing disruption and avoiding unnecessary damage.

Floor drain blockages can signal sewer-level issues. We use large-format drain cleaning machines suited to the larger pipe diameter, and often run a camera to rule out more serious underlying problems.

When using one drain causes a backup elsewhere, the blockage is typically in the main stack or sewer line — not individual fixtures. This requires immediate attention and proper diagnosis.

Sewage rising from your basement floor drain is a plumbing emergency. Stop using all fixtures immediately and call us. We clear the blockage, assess the cause, and advise on backwater valve installation to prevent recurrence.

Water or sewage backing up into sinks, tubs, or toilets means something is blocked downstream. We identify the location and severity of the obstruction and clear it with the appropriate equipment.

High-pressure water jetting scours the interior walls of drain pipes, blasting away years of grease, scale, and debris that snaking alone can't fully remove. We match the right jetter size to the pipe — residential lines differ from commercial mains.

All drain pipes in your home connect to the main sewer line — a blockage here affects everything. We clear it, then run a camera inspection to determine if a deeper repair is needed.

Tree roots invading sewer lines are extremely common in older GTA neighbourhoods. We cut and clear roots using chain knocker tools and hydro jetting. For a long-term solution, full sewer replacement may be recommended.

Backwater valves should be inspected annually. We service, inspect, and where needed repair or replace existing valves — and install new ones for homes that don't yet have this protection.

Drain clogs don't wait for business hours. We treat blocked drains as the plumbing emergencies they are and provide fast response across Toronto, the GTA, and surrounding areas. When to call an emergency plumber →

From small retail units to large commercial buildings, we handle the full scope of commercial plumbing — supply line installation and repair, fixture upgrades, pressure regulation, shut-off valve replacement, and ongoing maintenance contracts.

High-traffic retail and office washrooms demand fixtures built for sustained heavy use. We supply and install pressure-assist toilets, sensor faucets, commercial-grade flush valves, and full washroom plumbing upgrades — engineered to reduce maintenance calls and keep facilities running.

Commercial drains take on far more volume than residential lines. We clear blockages in commercial kitchens, washrooms, floor drains, and main sewer lines using industrial-grade equipment — including large-capacity hydro jetters designed for commercial pipe diameters.

Grease interceptors are required in commercial kitchens and are subject to municipal inspection. We install, service, and clean grease traps for restaurants, cafeterias, and food service operations across the GTA to keep you compliant and your drains flowing.

Commercial hot water demands exceed what residential units can handle. We supply and install high-capacity tank, tankless, and on-demand water heating systems for offices, restaurants, gyms, and multi-unit buildings — sized to your actual peak demand.

Commercial properties in Ontario are required to have backflow prevention devices tested annually by a certified tester. We install, certify, and test backflow preventers for commercial clients — keeping you compliant with municipal requirements.

Fitting out a new retail unit, restaurant, or office space? We handle all commercial rough-in plumbing from the ground up — sinks, floor drains, washrooms, kitchen lines, and appliance hookups — coordinated with your general contractor and completed to code.

A plumbing failure in a commercial setting means lost revenue, liability risk, and disrupted operations. We provide priority emergency response for commercial clients across Toronto, the GTA, and surrounding areas — any time of day. Know when to call →
