A kitchen sink is more than just a basin for washing dishes. It's a vital space in your home where water flows frequently and plumbing works overtime. But over time, wear and tear, aging components, and poor installations can lead to frustrating issues that affect both functionality and safety.
If you're experiencing slow drainage or a sink that's come loose from your countertop, it's crucial to identify the issue and address it effectively.
Why Identifying the Sink Issue Matters
Catching a sink issue early can be the difference between a minor fix and a major repair. As Curtis McGrath, one of our skilled plumbers, emphasizes, many problems "start small, like a bit of moisture or a small drip, but if left unchecked, that can escalate into cabinet damage, mould, or even a full re-piping job."
Likewise, understanding what's going on helps avoid unnecessary costs. For example, while a clogged drain might seem like a simple fix, if it recurs, it may signal deeper issues, such as corrosion or misaligned piping.
Leaky Faucet
Price Range: $300 - $650
A dripping kitchen faucet may seem harmless at first, but it's often a symptom of worn-out cartridges or internal seals. Over time, mineral buildup and daily use can wear down these parts, leading to persistent leaks around the handle or spout.
Aside from wasting water, a leaky faucet can lead to staining on your sink, damage to surrounding countertops, or mould growth if it drips underneath. Fixes usually involve replacing the faulty cartridge, tightening internal components, or, in some cases, swapping out the entire faucet fixture.
Clogged Drain
Price Range: $320 - $580
Kitchen sinks often clog due to a mix of grease, food particles, and soap scum that builds up in the drain over time. This slows water drainage or blocks it completely, making everyday tasks like washing dishes frustrating.
Using professional tools like augers or drain snakes, experts can quickly clear out even the most stubborn clogs. If clogs return frequently, it may indicate underlying issues such as pipe corrosion, misaligned plumbing, or more severe blockages that require attention.
Leaky Drain Fittings (up to 2)
Price range: $600 - $995
Drain fittings connect your sink's drain to the rest of the plumbing, and when they leak, the signs usually show beneath your cabinets. These leaks often go unnoticed until water damage, warping, or musty odours occur.
Causes range from aging or corroded fittings to installation errors, manufacturing defects, or other issues. Sometimes, a simple tightening or resealing is enough. In more severe cases, damaged sections of the drain line may need to be removed and replaced to ensure a proper seal.
Leaking P-Trap and Waste Arm
Price range: $720 - $1,200
The P-trap is the curved pipe under your sink that holds water to block sewer gases, while the waste arm connects it to the main drain line. Leaks here are typically noticed as puddles inside the cabinet or foul odours due to escaping sewer gas.
Common causes include corrosion, worn seals, or physical damage, especially if the system has been disturbed during drain cleaning. Depending on the extent of the damage, repairs may involve resealing joints or replacing the entire trap and waste arm for a long-term solution.
Reinstallation of Undermount Sink
Price range: $1,200 - $2,000
Undermount sinks are secured beneath the countertop, often with silicone and, ideally, brackets. Over time, poor adhesive or a lack of bracing can cause the sink to separate and fall, sometimes damaging the plumbing beneath.
Reinstallation involves removing the old silicone, applying a stronger sealant, and adding proper support brackets. This not only restores functionality but also prevents leaks and long-term structural damage to your countertop and cabinetry.
Emergency Valves (up to 3 Units)
Price range: $460 - $1,280
Kitchen plumbing typically includes up to three emergency shut-off valves for hot and cold water lines, as well as the dishwasher. When these valves fail, you may notice leaking, rust, or an inability to stop water flow during repairs.
Often, this failure results from the use of cheap or aging components. Replacement involves shutting off the main water supply and installing new valves, either by crimping or soldering, depending on whether your system uses plastic or copper pipes.
Ice Maker Copper Water Line (up to 10')
Price range: $710 - $1,200
If you've upgraded to a fridge with an ice maker or water dispenser, you will need a copper line to supply it with water that is usually run from your kitchen sink up to 10 feet away. This is not a repair issue, but rather a standard kitchen upgrade.
Installation can involve routing the line through the ceiling, cabinetry, or walls, depending on your layout. A professional plumber will ensure a secure connection and avoid drilling into wires, ducts, or other sensitive areas of your home.
