How Much Does It Cost to Fix a Leaking Pipe Under a Sink?

Fixing a leaking pipe under a sink is a common plumbing issue that many homeowners face. The cost to repair this type of leak can vary depending on several factors, including the severity of the leak, the type of pipe, and the plumber's hourly rate. Here's a detailed look at what you can expect to pay to fix a leaking pipe under a sink.

What is the price to repair a leaky pipe under the sink? Average Cost of Repair

On average, the cost to fix a leaking pipe under a sink in Canada ranges from $150 to $400. This estimate includes both the cost of labor and any necessary materials. For more complex repairs or if additional parts are needed, the cost could be higher.

Cost to fix a leaking pipe beneath a sink Factors Influencing the Cost

Several factors can influence the cost of repairing a leaking pipe under a sink:

  • Severity of the Leak: A minor leak that only requires tightening a fitting or replacing a small section of pipe will cost less than a major leak that requires extensive repairs or replacement of a large portion of the plumbing system.
  • Type of Pipe: The type of pipe material (e.g., PVC, copper, PEX) can affect the cost. For instance, repairing a copper pipe may be more expensive than fixing a PVC pipe due to the higher cost of materials and the need for specialized skills.
  • Access to the Pipe: If the leaking pipe is easily accessible, the repair will be quicker and cheaper. However, if the plumber needs to remove cabinetry or cut into walls to access the pipe, the labor costs will increase.
  • Plumber’s Hourly Rate: The hourly rate for plumbers can vary depending on their experience, location, and whether the repair is done during regular business hours or as an emergency service. In Canada, plumbers typically charge between $60 and $130 per hour.

Additional Costs

In addition to the basic repair costs, there may be additional expenses to consider:

  • Travel Fees: Some plumbers charge a travel fee, especially if they are coming from a significant distance.
  • Emergency Service Fees: If you need the repair done outside of regular business hours or require immediate attention, you may incur additional emergency service fees. For example, JZ Plumbing offers emergency services starting from $175.
  • Replacement Parts: If the repair requires replacement parts, such as new fittings, pipe sections, or seals, these will add to the overall cost.

DIY vs. Professional Repair

While some minor leaks can be fixed by homeowners with basic plumbing knowledge and tools, it's often best to hire a professional plumber to ensure the repair is done correctly and to avoid further damage. Attempting a DIY repair without proper knowledge can lead to more significant issues and higher costs in the long run.
