Durable Pipe Repairs

Broken Drain Lines Don't Fix Themselves

Many homes in Glendale, Pasadena and Burbank were built with cast iron or clay drain pipes. Those pipes did their job for decades, but time catches up. Cast iron rusts from the inside out. Joints shift. Cracks open up behind walls and under floors, and you usually don’t find out until there’s a smell, a stain or a drain that won’t stay clear.

We find the damaged section with a camera, show you exactly what we see, and repair it the right way. Sometimes that’s a short spot repair. Sometimes it’s replacing a run of old cast iron with modern ABS or PVC. Either way, you’ll know your options and your price before we start.

How Much Does Drain Line Repair Cost?

The cost depends on where the damage is and how we reach it:

Location: Under a slab or behind finished walls takes more labor than an open crawl space.
Length of damage: A single crack vs a full run of corroded old cast iron.
Repair method: Spot repair, full pipe replacement or trenchless lining.
Pipe material: Cast iron, clay, ABS or PVC.
Permits and restoration: Patching concrete or drywall after the repair is completed.

 Trustindex verifies that the original source of the review is Google. I recently had my entire house repiped, and I couldn’t be happier with the results! Richard was professional, punctual, and extremely knowledgeable throughout the whole process. They explained everything clearly, worked efficiently, and made sure my home was clean after each day of work.

The water pressure is amazing now, and it feels great knowing my plumbing system is brand new and built to last. Finding someone this reliable and skilled is rare—I highly recommend YLP plumbing to anyone needing repiping or any plumbing work done right the first time!

Common Questions

Drain Line Repair FAQs

Should I repair or replace my drain line?

If the damage is in one spot and the rest of the pipe is solid, a repair makes sense. If the camera shows widespread corrosion or multiple breaks, replacement or lining saves you money long term.

Will you need to break my slab?

Not always. We look at trenchless lining first. If we do need to cut concrete, we keep the opening as small as possible and patch it when we’re done.

Do I need a permit?

Many drain line replacements need one. We handle permits and city inspections when required.

How long does a repair take?

Spot repairs are often done in a single day. Larger underground or under-slab replacements can take two to three days.

Why is cast iron failing in my home?

Cast iron rusts from the inside over decades. In many older LA-area homes, those pipes are reaching the end of their functional lifespan.
