Leaking water line under a sink

Finding leaking water pipe or faucet is not something anyone looks forward to. When it happens, you should call a plumber right away to prevent further damage. But how much will it cost to repair?

The average homeowner will pay $300 repair a plumbing leak. However, it might only cost $50 or as much as $800. Plumbers typically charge $50 – $150 per hour.

The most significant consideration about repairing a plumbing leak is the leak’s location, what materials will you need to make the repair, and how long the repairs will take. The type of leaks, such as gas or water, will also affect the expense.

Cost to Fix a Dripping Faucet

One of the most common and often frustrating plumbing leaks is the dripping faucet. Not only are these leaky faucets irritating but can add to your water and water heating bill. This fix could be a DIY project if you have the time, tools, and talent, or a how-to book or video.

If not, expect to pay between $50 and $150. Some DIY and even professionals merely replace the entire faucet. This method is the easiest and most convenient, though finding and repairing the leak might be cheaper. It might only require a 50 cent washer.

Burst Pipes Repair Costs

Burst pipes can be a disaster, due mainly to water damage, but there’s also the expense of repairing walls, ceilings, and floors that might need to be torn out to make the repairs. Although the national average to repair drywall is $500, check out our drywall repair guide for more information on the cost of wall and ceiling repairs.

When the source of the burst pipe is easy to locate and repair, figure about $200 to $400 to repair the pipe.

Water damage could cost $1,000 to $5,000, depending on its extent. If the leak caused extensive damage, the bill for repairs could be even higher. Water damage allowed to set could cause mold and mildew growth, which might require a specialist to clean up and cost up to $2,500.

Leaking Pipes in Ceilings & Walls

Finding the leak within a ceiling or wall might require removing pieces of the wall or ceiling’s sheetrock, or other wall/ceiling coverings. Just because the leak appears in one area, does not mean the source is behind that section of the wall or ceiling.

It could require video scoping to determine where the source of the leak is. Expect to pay $100 to $400 to find the source of the leak and more for the repair. After you repair the pipe, you will need to repair the sheetrock or wall covering.

Septic or Sewer Line Leaks

Wherever the sewer line leak is, you will want to get it repaired quickly. Sewer leaks can contaminate well water, not only yours but your neighbors’ as well. Therefore, you will want to minimize damage by getting it repaired sooner rather than later. Replacing a section of pipe could cost as little as $500, and up to $1,500.

Leaks in the Water Mainline

The cost to replace the shutoff valve is between $150 – $300. The average price of a mainline repair is $750.

Leaks Under a Concrete Slab

Leaks under concrete are notoriously difficult to locate. When leaks occur under a concrete slab, you might need to jackhammer away the surrounding concrete to make the repair.

Leaks may also occur within floors where the pipes run to provide radiant heat. The concrete over radiant tubes is not as thick, but it still makes a mess and must get repaired. Finding the leak typically requires a video line inspection. These usually cost $400 or $500.

Repairing the leak could cost up to $5000 to find it, make the repair, and then repair the concrete slab and floor coverings. Learn more about the cost of removal and repair in our concrete slab removal price guide.

Gas Line Leaks

Everyone in your home should know where the main gas line shutoff is. When you suspect a gas leak, shut off the mainline, get out of the house, and call the gas company. DO NOT stay in the house to call.

It typically costs more to repair gas line leaks than water even though you need a plumber for either type of leak. You can expect to pay $300 – $750 for a gas line repair.

How to Find a Plumber
