Trenchless Sewer Repair & Pipe Lining in Los Angeles
A new pipe. Inside your old one.
Cured-in-place pipe lining renews a cracked or root-damaged sewer lateral without digging it up — typically 30–40% less than a dig-and-replace, with a 50-year design life. We install the Perma-Liner system: a resin-saturated liner inverted into your existing pipe and cured hard — a smooth, jointless new pipe with minimal excavation. Camera inspection first, flat-rate price before we start.

How pipe lining works.
Six steps, usually done in a day. You watch the before and after on camera.
Camera & clean
We inspect the full lateral on camera, then clean it — usually with hydro jetting — so the liner bonds to a sound host pipe.
Measure & map
Exact length and diameter come from the footage. Branch connections are mapped so every one can be reopened later.
Wet-out & inversion
The liner is saturated with resin, then inverted — turned inside-out — into the pipe, pressing the resin tight against the host wall.
Cure in place
Held under pressure while the resin cures hard, the liner becomes a structural new pipe inside the old one — with minimal digging.
Reinstate branches
Each branch connection is reopened robotically from inside the new liner — then verified on camera, one by one.
Final camera
You watch the finished line on screen: smooth, jointless, and flowing — proof the job is done before we pack up.
When lining is the right call.
Lining is powerful — but honest. Here's where it shines, and where it doesn't.
Cracked pipe, holding its shape
Cracks, separated joints, and root-entry points in a line that's still structurally sound — the liner bridges all of it.
Pipe under hardscape
Laterals running under driveways, patios, and landscaping you don't want torn up — lining needs only small access points.
Drains under the house
Secondary drains under the slab are perfect lining candidates — renew the pipe without breaking through your floor.
When lining is NOT the answer.
We'd rather tell you now than after the liner is in.
Collapsed sections
A flattened or collapsed pipe has no shape for the liner to follow — that section needs excavation or pipe bursting.
Severe bellies & back-pitch
A liner follows the old pipe's grade. Standing water and reverse slope stay problems after lining — the grade has to be fixed. Deep dive: sewer line belly.
Major offsets
Pipe sections shifted far out of alignment can't be bridged by a liner. The camera shows us exactly how far things have moved.

Pipe lining FAQ
Straight answers about trenchless lining.
How long does a pipe liner last?
A cured-in-place liner is a structural new pipe with a 50-year design life — independent of the old pipe around it. It's rated far beyond the clay, cast iron, or Orangeburg it renews.
Does lining make my pipe smaller?
Barely. The liner is thin, and its smooth jointless interior often flows as well as — or better than — the rough old pipe it replaces. We verify flow on the final camera run.
How long does a lining job take?
Most residential laterals are lined in a day once the pipe is cleaned and prepped. You'll have a straight timeline with your flat-rate quote before work begins.
What happens to my branch connections?
Every branch is mapped before the liner goes in, then reopened robotically from inside the cured liner and verified on camera — no digging to each connection.
Lining vs. pipe bursting — which do I need?
Lining renews the pipe from the inside and keeps the same diameter; bursting pulls a full new replacement pipe through the old line's path. Lining suits cracked-but-sound pipe; bursting suits lines that need full replacement. The camera decides.
Can you line the drains under my house?
Yes — secondary drains under the slab are some of the best lining candidates there are, because the alternative is breaking through your floor. If the camera shows the pipe is a fit, we line it with minimal disruption inside your home.
How much does trenchless sewer lining cost?
It depends on the line’s length, diameter, access, and condition — lining is usually priced by the foot, and every job is different. A camera inspection comes first so you can see the pipe’s condition, then we give you flat-rate options in writing before any work begins. Estimates are free.
