How Much Does It Cost To Replace A Sewer Line Under A Slab?

To get a general idea of how much it will cost to replace a sewer line under a slab, there are a few things to keep in mind: Price per foot, time frame, materials, permits, and permit fees. Read on for some tips to get the best deal. You may be surprised by what you learn. Read on to find out how much it really costs. There are a few different types of under slab plumbing.

Price per foot

If you are planning to install a new sewer line, you should consider the cost per foot before hiring a plumber. The cost can vary, but it will be around $150-200 per foot for a basic repair. The price per foot will depend on whether you need a trench or trenchless sewer line. For smaller jobs, you can save money by doing it yourself. However, if you’re working with a large project, the cost can increase to $20,000 or more per foot. The process of trenching under a slab may require $150-200 per foot.

In addition to the cost per foot, you should know that the plumbers must bring all of the necessary tools and materials to your property. In addition, they’ll have to dig up your yard in order to do the job. This means the price per foot to replace sewer line under slab will be more expensive than that of an ordinary replacement. Getting a professional estimate is therefore the best option. However, you should remember that this type of work is not for every homeowner.

The price per foot to replace sewer line under slab can range from $50 to $250, depending on the length of the sewer pipe and the material it is made of. You can expect to pay anywhere between $50 to $125 per foot, but the actual costs will depend on the pipe material and the length of the pipe. If you are planning to replace the entire sewer line, however, you may be better off figuring out who will be doing it yourself.

A good plumber will use the most expensive material available. If you have an older property, you should go with PVC pipes. They’re the most durable, and last for up to 100 years. You can also go with ABS pipes, which are made of rubber resin. ABS pipes can cost between $1.87 and $5.35 per foot and are available in ten-foot lengths. Cast-iron pipes last between 50 to 75 years before they need replacement.

Time frame

Whether your sewer line under your slab is leaking, or you’re just tired of paying top dollar for the repiping, you’ve probably wondered how long it will take to repair it. Fortunately, technology has advanced considerably in recent years. A licensed plumber can easily repair a broken pipe under a slab with a simple camera inspection. But you should always seek professional help before attempting the repair yourself.

Before tackling a repair or replacement, it’s important to get a good estimate. While it may be tempting to use a ballpark figure, it’s best to get an accurate estimate. The more thorough the inspection, the less you’ll have to pay. In addition, a trenchless approach can save up to 75 percent on labor costs. In this case, you can save money and time by lining your sewer line instead of having to tear up the concrete underneath it.

Having the pipe relined may not be your best option, but it can be a quick and inexpensive fix if you’re facing a leaking slab. Professional relining companies pull a liner into place and then cure it inside the pipe. Because the new pipe is laid outside the perimeter of the slab, future plumbing issues won’t require the same level of excavation. And you can save money by negotiating manual labor with the plumber.

If you’ve recently discovered a crack in your sewer line, you can call a plumber for emergency services. Your insurance company may cover the cost of the repair. However, if the problem originated beyond the sidewalk, you may have to pay for the repair yourself. Fortunately, this is not an uncommon situation. If you have a home warranty, your insurer may cover the costs. Otherwise, your best bet is to hire a professional plumber.

While repairing your sewer line is relatively easy, it can take a few days. It may take longer if you need permits or inspections. If you’re unsure, ask plenty of questions and get everything in writing – including the price – before the job gets underway. Many people panic when faced with an issue and try a temporary solution. This can end up costing you even more money. Instead, it’s better to hire a professional plumber who can do it quickly and efficiently.


Fortunately, there are many affordable materials available to replace a sewer line under a concrete slab. These materials are lightweight, easy to cut, and easy to install. A 4-inch plastic pipe can be purchased at any home center. You can also tie the new pipe into an existing cast-iron pipe for an extra-strong connection. While cast-iron pipe is associated with older homes, it is still used in new construction. Both PVC and ABS pipes are resistant to root anchorage and are relatively easy to install.

Clay sewer pipes are popular in older homes, but they have several disadvantages. Clay pipes are easily cracked, and they can get damaged by tree roots. These pipes are less common in buried infrastructure than other materials. Steel sewer pipes, on the other hand, are more durable and are easier to install. Unlike clay pipes, steel pipes do not rust easily, making them a more cost-effective option for sewer applications. However, steel pipes tend to be heavier than plastic and require smaller lengths. Consequently, they can develop more leaks over the life of the pipe.

Another option for replacing a sewer line under a concrete slab is pipe relining. A relining service uses four different types of pipe lining materials to repair a cracked or corroded pipe without digging it up. This method involves using a professional sewer and drain company to remotely line the affected section of the pipe. The company then cleans and dries the inside of the pipe, applying the lining. It is then cured in place using hot steam.

Another option for replacing a sewer line under a concrete slab is trenchless sewer lining. This process is much cheaper than a traditional excavation. Instead of digging up the concrete slab and replacing it with a new pipe, the plumber will replace the existing pipe with an epoxy lining. These new pipes can last between 50 and 80 years. However, the process is very time-consuming and expensive, and will leave you with more work than you expected.


If you need to replace your sewer line under your slab, you must obtain a permit first. While most plumbing work doesn’t require a permit, sewer line replacements may require one. The city may require you to have a permit if the work is on its property. Contact the building and safety department to get the proper permits. A plumber can help you get the required permit if needed. Pipelining is another option for replacing your sewer line. This process will cause minimal disruption to your property.

If you’re thinking about replacing your sewer line under the slab, you should remember that this job is not an easy one. There are many costs involved, including permits.

You’ll save hundreds of dollars in the long run.

Before you get started, make sure you check your local building and safety department’s website. They will have detailed information about plumbing permits for your county.
