Do you need drain pipe replacement after the results of sewer camera inspection? Consider pipe relining as a way to repair damaged underground pipes.
Pipe relining can apply to both your sewer line and water line, and it’s a great option compared to traditional pipe repair that requires complete evacuation.

What is Pipe Relining?
Pipe relining refers to the trenchless repair method in residential and commercial plumbing when coating the old pipe with a lining and then allowing it to harden. This creates a new pipe inside the old pipe by way of the new lining.
Relining pipes only requires small access points as opposed to traditional sewer repair that requires complete excavation.
There are two main types of internal pipe coating:
Spray in place relining (SIPP relining): SIPP uses a liner with an epoxy coating, while spray-in-place coating only uses the coating itself, meaning it doesn’t create as thick of a coating and won’t work properly in all situations.
The newly coated and relined pipe will last 50+ years.
Pipe relining services cost $70 per foot for long-distance jobs and $150 per foot for short-distance jobs. Unfortunately, homeowners insurance typically won’t cover plumbing repairs like this. (If water damage was the result of the problem, you can likely make a claim, though.)
Pipe relining offers the following advantages to traditional underground plumbing services:
- No disturbance of utilities
- Service connections reestablished from above ground
- Long-lasting results
- Smooth interior of new pipe can possibly increase water flow
- New industry standard

Why do I need relined pipes?
The number one reason people require trenchless pipe lining is a leaking pipe underground that is not easy to access.
A leak in your underground pipe or sewer lateral can cause a serious problem. If you notice signs of a leak or one is during professional leak detection, pipe relining may be the next course of action.
Alternatively, you may need emergency plumbing if you experience a severely broken pipe due to root intrusion or a frozen underground pipe.
How Does Pipe Relining and Coating Work?
The process starts by creating an access point and pouring or spraying a lining into the old pipe.
After the old pipe is properly coated it will cure or harden to form a new pipe lining unaffected by any sediment buildup or corrosion from the old pipe.
SIPP relining dries more quickly than CIPP relining.
Pipe relining will slightly reduce the diameter of your pipe, making pipe bursting the more ideal option when you’re worried about water pressure and water flow. However, pipe bursting won’t work if you have a blocked drain.
The bottom line is this. Your plumbing professional will recommend the best option for your sewer pipe relining job.
