Repipe Granada Hills: Replacing Aging Pipes in 1960s Tract Homes

If your Granada Hills home was built during the neighborhood’s rapid tract development era of the 1960s, there’s a strong chance the original plumbing is still working — or rather, struggling — behind your walls and under your slab. Those galvanized steel supply lines and cast iron drain pipes that were standard in that era have a finite lifespan, and for many homes in the Chatsworth Avenue corridor and throughout the Porter Ranch-adjacent neighborhoods, that lifespan is either up or nearly there. A repipe in Granada Hills isn’t a luxury upgrade — for many homeowners here, it’s a necessary fix to protect the home they’ve owned and maintained for decades.

At EZ Plumbing, we’ve been repiping homes across Los Angeles since 1989, and we know Granada Hills well. We’ve seen firsthand how the combination of older galvanized supply pipes and original cast iron drain lines creates a perfect storm of plumbing problems: low water pressure, rust-colored water, slow drains, recurring leaks, and sewage odors that no amount of drain cleaner will fix. These are symptoms of infrastructure that has simply reached the end of its useful life, and they won’t get better on their own.

Our licensed team (C-36 License #583868) handles complete whole-house repiping using modern copper or PEX piping for supply lines and ABS or PVC for drain replacements. We work efficiently to minimize disruption to your family, and we handle the permitting process with the City of Los Angeles so you don’t have to. Whether you’re a long-time Granada Hills resident or a property manager overseeing a rental home in the neighborhood, we’ll give you a clear, honest assessment before any work begins.

Why Granada Hills Homes Need Repiping Now

The 1960s construction boom that shaped Granada Hills produced thousands of nearly identical tract homes with nearly identical plumbing systems — and those systems are now 55 to 65 years old. Galvanized supply pipes corrode from the inside out, gradually narrowing until water flow becomes a trickle and rust flakes make their way into sinks and showers. Cast iron drain lines, meanwhile, crack, root-intrude, and corrode at joints, often showing no visible signs until a backup or a slab leak forces the issue. We regularly perform Granada Hills repiping projects where homeowners had no idea how compromised their drain system was until we ran a camera inspection. The good news: catching it before a major failure saves thousands in water damage repairs.

What the Repipe Process Looks Like for Your Home

A typical repipe in Granada Hills begins with a free on-site evaluation where we assess your current pipe material, condition, and layout. From there, we provide a detailed written estimate. During the repipe itself, our crew accesses pipes through strategic wall and ceiling openings — kept as small as possible — and replaces the full run of supply lines or drain lines depending on the scope. Most whole-house repipes are completed in one to two days. We patch drywall, restore water service before we leave, and schedule a final inspection. Many Granada Hills homeowners tell us they wish they hadn’t waited as long as they did. When you’re dealing with a 60-year-old system, Granada Hills repipe work done proactively is always less expensive than emergency repairs after a failure.

Frequently Asked Questions About Repiping in Granada Hills

My Granada Hills home still has the original cast iron drain lines — do they all need to be replaced at once?

Not necessarily, but we strongly recommend a camera inspection before deciding. Cast iron from the 1960s degrades unevenly — some sections may be structurally sound while others have significant cracking or corrosion at the joints. We’ll show you exactly what we find on camera and give you options for a phased approach or a full replacement, depending on the condition. Partial repiping in Granada Hills homes is common when budget is a concern, as long as the remaining sections are documented and monitored.

Will a repipe require me to open up all my walls?

We minimize wall disruption as much as possible. For supply line repiping, we typically access pipes at key junction points and use flexible PEX tubing to navigate around obstructions without cutting every wall section. For cast iron drain replacements under a slab, some concrete cutting may be required, but we restore everything before the job is complete. Our goal is to leave your Granada Hills home functional and clean — not torn apart.

How do I know if my water pressure issues are from galvanized pipes or something else?

Low water pressure in a 1960s Granada Hills home is one of the most common signs of galvanized pipe buildup. Over decades, mineral deposits and corrosion narrow the interior diameter of galvanized steel pipes significantly. We can test your pressure at multiple points in the home and run a quick inspection to determine whether the source is your supply pipes, your water heater, or the main line. In our experience, when a Granada Hills home has both low pressure and discolored water, galvanized pipes are almost always the cause.

Does EZ Plumbing handle the permits for a repipe in Granada Hills?

Yes — we manage the entire permitting process with the City of Los Angeles on your behalf. A repipe is a permitted job, and pulling the proper permits protects you as the homeowner, ensures the work meets current code, and is essential if you ever sell the property. We schedule and coordinate the required inspection so you don’t have to navigate the city process yourself. It’s part of how we’ve built our reputation in this area since 1989.
