Most residents have their doubts about the modern techniques of trenchless sewer repair. So when they decide to repair the sewer pipes in their homes in West Seattle, WA, they opt for the traditional method of excavation.
Do you know what you have on your hands when you opt for the traditional method?
- A ruined beautiful lawn.
- A front driveway with patches of cement.
- Hefty labor charges.
- The huge cost of a replacement pipe.
- The time and money to re-grow a beautiful lawn.
So if you intend to repair or replace your damaged sewer pipes, don’t go for the age-old excavation method. Unless of course, the initial camera inspection reveals that the roots of the tree in your lawn have grown into the sewer pipe.

Trenchless Repair Method
The sewer pipes in your house will first be flushed with pressurized water to clear the pipes of all debris and other material sticking to the walls of the pipes. Our plumbers insert a non-woven felt tube with outer and inner polyethylene sleeves in the damaged sewer pipe.
Then we pump a liquefied thermosetting resin into the felt tube to completely soak the felt lining with the resin. The thermosetting resin will later form an impervious lining inside the damaged pipe.
A flexible pipe which is called the bladder is inserted into the felt and polyethylene sleeve assembly. We fill the bladder with pressurizing fluid to inflate it. Depending on the type of thermosetting resin used, the curing fluid may be air, hot water, or steam. We maintain the pressure inside the bladder for the time it takes for the resin to set and form the new lining of the pipe.
Once the curing time is reached the pressure of the fluid in the bladder is removed and the deflated bladder pipe is removed from inside the pipe. We then test the new pipelining for integrity.
This method is a replacement technique rather than a lining technique. We go with this method when the damage to your sewer pipes is extensive.
Our plumbers fit a cone-shaped bursting assembly at the end of a new pipe. We then insert this cone in the damaged pipe. After applying force to the old pipe, we burst it away and replace it immediately with a new pipe.
