LightRay UV sewer lining in Spokane Valley, WA

A resin-soaked liner goes into your old sewer and cures hard under UV light, forming a new seamless pipe inside the old one. No trench across the yard, and the lining itself takes a few hours.

Know the signs

Lining, bursting or open trench?

Three ways to fix a sewer. The camera shows which one your line can take, and we tell you plainly.

Lining

The old pipe still holds its shape. A liner seals cracks, joints and root entry points inside it, with little digging and sometimes none.

A patch

One bad spot in a sound line can take a patch in place up to 5 feet long, a semi-permanent fix for that spot.

Pipe bursting

The old pipe is collapsed, crushed or Orangeburg. A new seamless pipe is pulled through as the old one breaks apart.

Open trench

The line has a belly or offsets nothing can pass. Lining and bursting follow the old path, so we dig.

How it works

Film. Clean. Line. Film again.

Most residential lining jobs are finished in one day.

  1. 01

    Film

    The camera confirms the pipe is a lining candidate and finds every side connection.

  2. 02

    Clean

    Roots and scale are cut out and the pipe is cleaned.

  3. 03

    Line

    The liner goes in and cures under UV light. Hold off on water for that window.

  4. 04

    Verify

    Side connections are reopened and the camera checks the finished pipe.

Questions

LightRay UV sewer lining, answered.

Answers from licensed plumbers. Still unsure? Call (509) 535-5946, 24 hours a day.

What is LightRay UV sewer lining?
It is cured-in-place pipe: a resin-soaked liner is pulled into your existing sewer and hardened with UV light, forming a new seamless pipe inside the old one without a trench. Gold Seal is the region’s exclusive LightRay UV provider.
How much does trenchless sewer lining cost?
At Gold Seal, lining starts from $6,426 for up to 50 feet and $8,775 for up to 100 feet, and a patch over one spot starts from $4,116. Lining equipment, descaling and permits are their own lines on the free estimate, and LightRay UV repairs are $500 off right now.
When is lining not the right choice?
When the pipe is collapsed, badly deformed or out of alignment, or has a belly that holds water. Lining rebuilds a pipe along its existing path but does not correct its slope; pipe bursting or an open trench handles those lines.
Will lining stop roots for good?
Along the lined section, yes. Roots get in through joints and cracks, and a seamless liner leaves them no way in, provided the whole affected run is lined.
How long does sewer lining take?
The lining itself takes a few hours. Most residential jobs, with the cleaning and the camera before and after, are finished in one day, and you will be asked not to run water while the liner cures.
