Sewer lining vs. replacement: a Front Range decision
Clay bells, orangeburg, expanding soils, and when a liner is a 50-year fix — or an expensive postponement.
Expanding clay soils pull joints apart. Cottonwoods find the drip. Orangeburg goes oval. None of that is a moral failing of the house — it is the Front Range. The mistake is choosing lining or replacement from a postcard, not from a camera.
Lining wins when
- The pipe is still mostly round
- Defects are cracks and offset joints, not a collapse
- You want to keep flagstone, mature trees, or a new driveway
- The pitch is still there — lining cannot fix a belly full of water
Replacement wins when
The pipe is collapsed, orangeburg that’s mush, or sitting in a belly. A liner needs a host. If the host is gone, you are buying a pretty tunnel into the next backup. A short, honest dig on the bad section plus a camera of the rest is often the grown-up quote.
Ask for the video
If a company will not show you the footage, they are selling a method, not a diagnosis. We keep the file. You should too — the next buyer of the house will ask.
