Sink and Faucet Repair Montreal: Expert Kitchen & Bathroom Solutions
A dripping tap or a leaking sink rarely fixes itself — it just wastes water, drives up your bill, and gets worse the longer it’s ignored. Our Montreal plumbers repair, replace, and install kitchen and bathroom faucets, along with the sinks and supply lines behind them, using quality parts and workmanship we stand behind.
Whether it’s a worn washer, a failing cartridge, low water pressure, or a sink that won’t stop leaking at the base, we diagnose the actual cause before we touch a wrench — so you’re not paying to replace parts that didn’t need replacing.
Available across Montreal and surrounding boroughs, with fast same-day response times for dripping taps, sink leaks, and urgent fixture repairs.

Common Faucet and Sink Problems We Fix
Faucet and sink problems can disrupt your daily routine, damage cabinetry, and quietly waste thousands of litres of water each year. Our licensed Montreal plumbers diagnose and resolve every type of kitchen and bathroom fixture defect:
Dripping or leaking faucets
A faucet that keeps dripping after it’s shut off almost always points to a worn washer, a damaged O-ring, or a cartridge that’s reached the end of its life. We identify which one it is and replace only what’s needed, restoring a silent, watertight seal.
Low or inconsistent water flow
If water pressure at the tap has dropped or flow feels irregular, the cause is often a clogged aerator, mineral buildup in the aerator screen, or a partially blocked supply line. Most of the time this is a quick fix once the blockage is cleared or the aerator is replaced.
Faucet won’t turn on, feels stuck, or the handle is loose
This usually comes down to internal valve wear, mineral scale seizure, or a handle mechanism that’s loosened over time. We repair or replace the internal valve and handle assembly so the faucet operates smoothly and securely again.
Leaking at the base or around the spout
Water pooling around the base of the faucet or dripping along the swivel spout is a common sign of a failed seal, worn O-ring, or a valve body gasket that needs replacing — not necessarily a sign you need a whole new faucet fixture.
Sink leaks and undersink plumbing issues
Beyond the faucet itself, we handle leaks at sink connections, braided supply lines, shut-off valves, slip-joint washers, and drain fittings (P-traps, tailpieces, and basket strainers) for both kitchen and bathroom sinks to keep cabinets bone dry.
Faucet replacement and installation
When a repair no longer makes sense — because the fixture is old, corroded, damaged, or you’re upgrading your kitchen or bathroom aesthetics — we handle full faucet replacement and professional installation, matching new fixtures properly to your existing plumbing lines.
Faucet Types & Internal Cartridge Mechanics
Modern faucets vary substantially in their internal engineering. Knowing how your specific fixture controls water volume and temperature allows our plumbers to source the exact OEM replacement parts and execute precise, durable repairs:
Cartridge Faucets (Single & Dual Handle)
Commonly found in Moen, Delta, and Kohler fixtures. A brass or plastic cartridge moves up and down to regulate flow and rotates to blend temperatures. When internal O-rings or rubber grommets deteriorate, the cartridge must be extracted and replaced.
Ceramic Disc Faucets
State-of-the-art tap technology featuring two diamond-hard ceramic discs that slide against each other. Nearly impervious to wear, leaks usually only occur if sand, grit, or mineral sediment gets trapped between the disc faces or if silicone seals degrade.
Ball Faucets (Single-Handle Kitchen Mixers)
Frequently installed in older kitchen setups. A slotted brass or plastic ball rests over spring-loaded rubber seals. Leaks typically develop when the rubber seats wear down or mineral scale scores the rotating metal ball surface.
Compression Valve Faucets
Traditional dual-handle fixtures where turning the knob screws a threaded brass stem down against a valve seat. A rubber washer at the base compresses to stop flow. Over time, friction squashes the washer, requiring washer and seat replacement.
Pull-Down & Pull-Out Sprayer Hoses
Kitchen faucets with retractable spray wands rely on flexible nylon or stainless-braided hoses weighted beneath the sink. Constant pulling can cause friction tears or hose connection leaks, resulting in hidden water pooling inside cabinetry.
Undersink Shut-Off Valves (Angle Stops)
Dedicated isolation valves beneath your sink allow localized water shut-off. Older multi-turn gate valves frequently seize up or weep water when touched; we upgrade them to modern, reliable quarter-turn ball valves.
Our Diagnostic & Repair Process
We take a systematic, honest approach to every plumbing service call. Rather than jumping to costly fixture replacements, our licensed technicians follow a structured four-step procedure:
Precise Diagnosis & Isolation
We inspect the faucet, sink basin, supply hoses, and drainage connections. We isolate the shut-off valves and test water flow and pressure to pinpoint the exact failure point before loosening a single fastener.
Careful Disassembly
Using specialized non-marring tools, we safely remove handles, decorative escutcheons, and retaining nuts without scratching delicate chrome, matte black, or brushed nickel finishes.
Targeted Repair or Component Replacement
We clean internal mineral scale, replace defective cartridges, stems, O-rings, or aerators with high-grade manufacturer-matched parts, or replace damaged braided supply lines and P-traps.
Pressure Testing & Verification
We restore full water pressure, cycle the hot and cold supplies, inspect all connections with high-intensity lighting for micro-leaks, and verify smooth, uniform aerated water flow.

Frequently Asked Questions — Sink & Faucet Repair Montreal
Answers to common homeowner questions about dripping taps, leaking sinks, cartridge replacements, and repair costs in Montreal.
Why is my faucet dripping even when it’s fully closed?
A constant drip after shut-off is typically caused by a worn rubber washer or a deteriorated internal cartridge that no longer creates a watertight seal against incoming line pressure. In modern single-handle faucets, microscopic scratches or degraded O-rings on the ceramic disc or plastic cartridge allow water to weep through. Both are straightforward to replace once the faucet model and brand are identified.
Why is the water flow from my faucet weak or uneven?
Weak or irregular water flow is most often caused by mineral deposits and calcium scale clogging the fine mesh aerator screen screwed onto the tip of the spout. However, it can also point to a partially blocked supply line or a shut-off valve that isn’t opened fully. Cleaning out the mineral sediment in vinegar or replacing the aerator with a new unit resolves the issue in most cases.
Why does my faucet leak from the base?
Leaking around the base or where the spout swivels usually means the internal O-ring, valve body seal, or cartridge gasket beneath the handle has worn out, allowing water under pressure to escape sideways rather than traveling through the spout. It’s a targeted repair requiring O-ring replacement, not a reason to replace the entire faucet fixture.
Can a stuck or hard-to-turn faucet handle be repaired?
Yes. A stiff or stuck handle is generally caused by internal valve wear, corroded stem threads, or heavy mineral scale binding the rotating components inside the faucet body. It can usually be repaired by taking the handle apart, cleaning the mineral buildup, lubricating the mechanism with plumbing-grade silicone grease, or replacing the internal valve cartridge rather than buying a whole new faucet.
Should I repair my faucet or replace it?
If the fixture body is in good physical condition, matches your bathroom or kitchen décor, and the problem is isolated to a replaceable part like a cartridge, washer, O-ring, or valve, repair is usually the far more cost-effective option. Replacement makes more sense when the faucet is old, the brass casting is internally corroded or cracked, parts are obsolete, or you’re updating the aesthetic look of your room.

Yes, we provide comprehensive service for both kitchen and bathroom sinks and faucets.
