CIPP Epoxy Pipe Lining in Boulder, CO
Reline a cracked clay or cast iron sewer line from the inside with a resin-soaked liner that cures into a smooth new pipe wall, usually with little or no digging.
CIPP Epoxy Pipe Lining in Boulder
Cured-in-place pipe (CIPP) lining puts a new pipe inside the old one. A felt liner soaked in epoxy resin is inserted through a cleanout and cured in place, sealing cracks and root entry points. It suits Boulder homes where the old clay or cast iron pipe still holds its shape, especially where the line runs under a driveway, porch or mature tree.
Signs you may need this
- Cracks or root entry at joints, but the pipe is still round
- Cast iron with scale buildup or rough interior walls
- The line runs under a driveway, patio or large tree
- An accessible cleanout is available or can be added
How it usually works
- 1
Scope and measure
A camera inspection confirms the pipe is a good lining candidate and measures the run.
- 2
Clean the line
The pipe is hydro-jetted to remove roots, scale and debris so the liner can bond.
- 3
Insert the liner
The resin-soaked liner is inverted or pulled into the old pipe through an access point.
- 4
Cure and reopen
The liner cures with hot water, steam or light, then any branch connections are reopened.
- 5
Final camera pass
A last inspection records the finished liner for your files.
What affects the price
Typical range: $100 - $160 / ft + setup. Your exact price is set after an on-site look.
Pipe condition
Lining needs a pipe that still holds its shape. Collapsed sections must be dug and repaired first.
Length and diameter
Longer runs and larger diameters use more liner and resin.
Bends and branches
Multiple bends or connections that must be reinstated add labor.
Access
An existing cleanout keeps setup simple. Adding one raises the price.
Questions homeowners ask
Can every sewer line be lined?
No. Lines that are collapsed, badly offset or sagging usually need replacement or a spot dig before lining is possible.
Does lining shrink the pipe?
Slightly, since the liner adds wall thickness. The smooth interior usually keeps flow similar to or better than an old rough pipe.
How long does CIPP lining last?
Cured liners are designed for a long service life. Your contractor can share the specifications of the product they install.
