CIPP, or Cured-in-Place-Pipe Lining, is a trenchless technique for repairing sewers. Compared to other sewage repair techniques available in Mount Vernon, it takes a lot less time to complete and requires little to no digging. Both short and long lines of pipes that do not require sizing up can be repaired with it.

In CIPP, a flexible liner is inserted into an existing pipe, inflated, and then the liner is exposed to heat or UV light to dry and harden it. In essence, the liner creates a smooth surface inside the old pipe, basically renewing it. We recently updated a home’s sewer line using cure-in-place plastic pipe lining. The work took place in Mount Vernon WA.

The Problem

The rental home kept experiencing clogged and backed-up sewage. The majority of pipe problems take place within the foundation or inside the walls of your house or place of business. Fortunately, there are some indicators you may look for to identify whether your pipes require expert attention. 

Low water pressure, leaky faucets, loud pipe noises, strange scents emanating from the inside or outside of your home, constantly clogged fixtures, interior or outside floods, and a lack of hot water are all signs that your pipes need to be repaired.

The Process

We scoped the line using our sewer camera. The sewer line was originally constructed of old concrete tile pipes. The sewer line was neatly 100 years old and well beyond its life expectancy. You see the pipe simply wore out. The flow path in the pipe was worn out leaving exposed aggregate as the mortar washed away. This leaves the line very rough with cracks and holes developing inside the pipe. This old line became more like sandpaper instead of smooth. Sewage hangs up and no longer smoothly exits on our sewer pipes.

Luckily there are more modern methods to update these old failing lines. In past times the lines had to be completely replaced by excavating and replacing. This is very destructive and costly. This is compounded because many municipalities hold property owners responsible for the sewer line out in the street. Street excavations get very costly due to many complications like road pavement restoration, traffic control, and permitting.

In this case, we worked directly with City engineers and inspectors and were able to update the line by installing a cure-in-place plastic pipe liner / CIPP liner. We even updated the lateral sewer line out in the street without excavating the road at all.

Why Use CIPP Lining?

The following are the key advantages of acquiring CIPP lining for your damaged pipes over trenchless pipe lining:

Far More Cost-Effective Than Conventional Techniques

Older pipe repair techniques required a large team, a lot of digging, and heavy equipment. Pipe lining businesses can swiftly and effectively address the base of the problem without overly extensive digging or taxing machinery thanks to contemporary technology and tools. Because of this, the service is ultimately more economical for both the client and the business.

Stops Pipe Leaks

Pipe leaks can be expensive and time-consuming to fix, especially if they cause flooding or water damage inside the house. Water and waste can leak through pipes as they age and deteriorate, which gives them a chance to do so. To stop leaks and reduce pipe shock, a protective layer is placed against the pipes during the CIPP pipe lining process.

CIPP Lining Reduces Time and Effort

The CIPP lining procedure can be completed in less than three hours thanks to the latest tools and technology now in use. The entire procedure depends on how complicated the project is and what the professionals involved are asked to do.

It is important to always check with your sewer and drain specialist or the contractor doing the work for instructions and guidelines, as often the services may be temporarily unavailable during the lining process:

  • Avoid using water-intensive equipment, such as showers, bathtubs, washing machines, and dishwashers.
  • Disconnect all sump pumps from the sewage line.
  • Use toilets only occasionally.
  • Do not continuously pour or run water down the drain.

These steps are crucial because, while the pipe lining operation is taking place, connections from private properties to the public sewer will be temporarily shut off. To avoid water from backing up into a residence during the pipe lining process and filling a private sewer line, less water must be used.


CIPP lining saved a lot since the whole side sewer was updated with only 2 relatively small excavations. We have been helping people resolve their sewer line issues for over 20 years. We work in the greater Puget sound area including Mount Vernon.
