Repipe North Hollywood — Replace Aging Pipes in Your Home or Apartment

If your property was built in the 1960s or 1970s, there is a strong chance the original galvanized steel pipes are still buried in the walls — and they are almost certainly past their useful life. North Hollywood is packed with two- and three-story apartment buildings from that era, and our team at EZ Plumbing sees the same story play out constantly: weak water pressure on the upper floors, rusty discoloration at the tap, and pinhole leaks hiding inside drywall for months before anyone notices. A repipe in North Hollywood is not a luxury upgrade — for many of these older buildings, it is the only permanent fix.

Multi-unit properties along Lankershim, Oxnard, and the residential corridors south of Magnolia present a particular challenge because the original galvanized supply lines feed multiple units off a single riser. When one section corrodes, water pressure drops for every tenant on that stack. Property managers often spend years paying for repeated spot repairs, not realizing the cumulative cost already exceeds what a full repipe would have cost. We work directly with building owners and property managers to schedule repiping work unit by unit, minimizing disruption to tenants and keeping the building occupied throughout the project.

EZ Plumbing has held a California C-36 plumbing license (License #583868) since 1989 and has repiped dozens of properties across the San Fernando Valley. We are familiar with the specific wall construction and pipe routing common to North Hollywood’s post-war apartment stock, and we pull all required City of Los Angeles permits so your work is fully documented and code-compliant.

Why Galvanized Pipes in North Hollywood Buildings Fail Sooner Than You Expect

Galvanized steel was the standard material for residential plumbing through most of the 1970s, but it has a design lifespan of roughly 40 to 50 years. Most North Hollywood buildings built in that window are now well beyond that mark. The corrosion process works from the inside out — mineral deposits and rust accumulate on the pipe walls, steadily narrowing the interior diameter and reducing flow. By the time rust-colored water appears at the faucet, the pipe walls are already dangerously thin. In areas with shared sewer laterals, aging drain lines compound the problem: grease buildup from neighboring restaurant drain lines and years of organic debris can back up into residential laterals, adding drain replacement to the scope of a repipe project. Our technicians assess both supply and drain lines during every evaluation so you get a complete picture before any work begins.

What to Expect from a Repipe in North Hollywood

We replace galvanized supply lines with copper or PEX tubing depending on the building layout and owner preference. PEX is especially practical in older North Hollywood apartments where wall access is tight, because its flexibility reduces the number of cuts needed to route new lines. A typical single-family home repipe is completed in one to two days. Multi-unit buildings are phased so water is only shut off to one section at a time, usually for four to six hours per phase. After installation, we pressure-test every line before patching walls, and we coordinate the final inspection with the City of Los Angeles building department. From the first call to the signed inspection card, we manage the entire process.

Frequently Asked Questions About Repipe in North Hollywood

My apartment building has eight units — do all of them need to be vacated during a repipe?

No. For multi-unit buildings in North Hollywood, we repipe one section or riser at a time so most units remain occupied and functional. Tenants in the active work zone typically experience a water shutoff of four to six hours per phase. We schedule shutoffs in the morning and restore water before the end of the business day whenever possible, which is especially important for buildings with a high number of long-term renters.

Can rusty water from old galvanized pipes in my 1970s building cause health or liability issues?

Corroded galvanized pipes can leach iron and other minerals into the water supply, which discolors water and affects taste. While low-level iron is not acutely toxic, the degraded pipe condition itself creates liability exposure for property owners — particularly if a pinhole leak causes water damage to a tenant’s belongings or the building structure. Documenting a completed repipe with a City of Los Angeles permit also protects you if a future insurance or sale inspection raises questions about the plumbing system.

Is PEX or copper better for a repipe in an older North Hollywood apartment building?

Both materials are durable and code-approved. Copper has a long track record and is preferred by some owners for its rigidity and resale perception. PEX is more flexible, which means fewer wall openings in buildings where pipes were originally run through tight or irregular framing — very common in North Hollywood’s 1960s-era construction. We assess your building’s specific layout and give you an honest comparison of cost, access requirements, and long-term performance before you decide.

We have a restaurant on the ground floor of our mixed-use building — does that affect the repipe scope?

Yes, and it is something we specifically watch for in North Hollywood’s mixed-use corridors. Commercial kitchen drain lines carry heavy grease loads, and in older shared lateral systems that grease can migrate into residential drain stacks over time. If your building has a restaurant tenant, we inspect the drain lines alongside the supply lines and can include grease-affected sections in the repipe scope. Addressing both at once avoids a second round of wall openings and permits down the road.
