What CIPP Lining Does
Cured-In-Place Pipe (CIPP) lining is a trenchless method for rehabilitating damaged or deteriorating sewer lines without replacing them. A felt or fiberglass liner saturated with epoxy resin is inserted into the existing pipe, inflated to press against the walls, and then cured — using hot water, steam, or UV light — into a hard, seamless pipe inside the old one.
The result is a structurally independent pipe that seals cracks, covers root entry points, spans offset joints, and restores full flow capacity. No excavation required.
What Lining Fixes
- ✓Hairline cracks and stress fractures in the pipe wall
- ✓Corrosion in cast iron lines
- ✓Root entry points at pipe joints (epoxy surface is impenetrable to roots)
- ✓Minor joint offsets and separations that would otherwise require spot excavation
- ✓Age-related deterioration in clay tile pipe
- ✓Leaking lateral connections and service connections
The Five-Step Lining Process
Camera inspection
We document the pipe's current condition and confirm lining is structurally appropriate.
Cleaning and preparation
The pipe is cleaned thoroughly — roots, debris, grease, and scale removed so the resin bonds directly to the wall. Heavy cast iron buildup may require mechanical pipe descaling before hydro jetting.
Liner installation
The resin-saturated liner is positioned inside the pipe using air pressure or a pull cable from the access point.
Curing
Hot water, steam, or UV light activates the resin, hardening the liner to the pipe wall. This typically takes 2–4 hours.
Final camera inspection
We verify the new surface, confirm full diameter, and document the finished liner before closing up.
Preparing the Pipe for Lining
CIPP lining requires a clean host pipe — the epoxy must bond directly to the wall. When aging cast iron or clay laterals have heavy rust scale or mineral buildup, we recommend mechanical pipe descaling before lining. Descaling restores the interior diameter; lining then seals and reinforces the pipe structurally.
If the pipe is too deteriorated for lining to be effective, we will recommend trenchless replacement or traditional excavation instead.
50-Year Service Life
A properly installed CIPP liner is rated for 50 years. The epoxy surface is non-corrosive, impermeable to water infiltration, and smooth enough to actually improve flow rates in pipes that previously had heavy mineral buildup. Our installations come with a written guarantee covering materials and workmanship.

Terrain
Generally flat northwestern Valley terrain with standard sewer laterals; some larger lots have longer runs to the street main.
Trees & roots
Mature landscaping around older homes increases root-intrusion risk in aging laterals.

Common questions about pipe lining
What is CIPP pipe lining?
Cured-In-Place Pipe (CIPP) lining inserts a resin-saturated liner into your existing sewer line, inflates it against the pipe wall, and cures it into a hard, seamless pipe inside the old one. It seals cracks, stops leaks, and blocks root entry — all without excavation.
Will lining reduce my pipe's interior diameter?
Slightly. The liner wall is typically 5–8mm thick. For a standard 4-inch residential pipe, this reduces the interior by less than 10% and has no measurable impact on flow — the smooth epoxy surface actually improves flow compared to a corroded or scale-coated original.
Can you line a pipe that has tree roots in it?
Yes, but the roots must be removed first. We use mechanical cutting and pipe descaling followed by hydro jetting to clear the pipe completely. The cured epoxy liner then creates a sealed interior surface that roots cannot penetrate.
How does CIPP compare to pipe bursting?
CIPP lining is ideal when the existing pipe's structure is largely intact but has cracks, leaks, or root entry points — the liner reinforces what is already there. Pipe bursting is used when the pipe is too deteriorated to serve as a structural guide and a completely new pipe is needed.
Does the pipe need to be cleaned before lining?
Yes. The host pipe must be free of scale, grease, and debris so the epoxy bonds directly to the wall. Heavy cast iron buildup may require mechanical pipe descaling before hydro jetting — we handle both steps when needed.
How long does pipe lining take?
Most residential CIPP projects complete in a single day. The curing process itself takes 2–4 hours depending on the liner material and method used, with camera verification before we close up.
Common questions about plumbing in Northridge and nearby communities
Why start with a camera inspection in Northridge?
Housing ages and remodel histories vary block by block. Video shows whether you have clay, cast iron, or PVC — and whether roots, offsets, or collapse are the real problem.
Do earthquake-era remodels change plumbing codes?
Remodeled sections should meet the code in force at the time of work. We evaluate what’s actually in the ground/walls rather than assuming everything matches the original build year.
Can you clear a main-line backup same day?
Yes in most cases. We clear the line, camera it, and give you a flat-rate recommendation if repair is needed.
