Repiping Brooklyn Homes: From Galvanized to Done-Right
Hundred-year-old galvanized steel rusts from the inside until a pipe that started at three-quarters of an inch flows like a drinking straw. That’s where the weak shower, the rusty morning water, and the repeat pinhole leaks come from.
Repiping replaces the failing system instead of patching its symptoms: whole-house or phased, copper or PEX, in occupied homes, with the walls restored and the permits filed.
Signs Your Building Is Asking for It
- Weak pressure that collapses when the second fixture opens — the signature of occluded galvanized.
- Rust-tinted water first thing in the morning, clearing as it runs.
- Pinhole leaks that keep returning to different spots on the same era of pipe.
- Gray threaded-steel supply piping visible in the basement — original galvanized, on borrowed time.
- A renovation in planning: walls opening anyway is the cheapest repipe you will ever be offered.

What Repiping Involves in an Occupied NYC Home
The order of operations is built around one promise: water on every night. New mains and risers go in alongside the old where possible, branches move over fixture by fixture, bathrooms are sequenced so one always works, and the old system comes out only when the new one is carrying the house. Wall openings are cut cleanly and mapped, and we coordinate the restoration.
Brownstones get the extra respect their plaster and woodwork demand: routing that favors closets, chases, and existing paths, and PEX where it saves walls without compromising the system.
The Renovation Pairing
If a kitchen, bath, or gut renovation is in your future, sequence the repipe into it — open walls make it dramatically cheaper, and new fixtures deserve better than century-old supply lines. It's also the natural moment for the upgrades that ride the same pipes: whole-house filtration → and radiant floor heating →
Permits, and Why They're Part of the Value
A repipe is permitted work: DOB filings by the installing Licensed Master Plumber, inspections, and sign-off — closed out properly, so the project that fixed your water also cleans your building record. When you sell, the documented repipe answers the buyer's inspector in advance.
FAQ
Frequently Asked Questions
How do I know my home needs repiping rather than repairs?
The signals: pressure that drops when a second fixture opens, brown or rusty water after the tap sits overnight, repeat pinhole leaks in the same runs, and any remaining galvanized supply piping — visible as gray threaded steel in the basement. One failing section can be repaired; a failing system re-announces itself every season until it’s replaced.
Copper or PEX?
Both are legitimate, and we install both. Copper is the proven century material — rigid, time-tested, and what most NYC inspectors grew up with. PEX runs faster through finished buildings (fewer wall openings, fewer joints) and shrugs off the acidic-water pinhole problem. Many of our repipes mix them: copper where exposed and at the service, PEX through the concealed runs. The estimate spells out what goes where and why.
How long does a repipe take, and can we live in the house?
Most one- to four-family repipes run several days to two weeks depending on scope and access, and homes stay occupied. We phase the work so water is back on every night, protect and close up as we go, and sequence bathrooms so one always works.
What drives the cost?
Five things: the size of the system (fixture count and floors), access (open basement ceilings are cheap; plaster walls are not), material choices, what the walls need afterward, and the permit scope. A written, itemized price follows the walkthrough, and where a phased repipe spreads cost across seasons sensibly, we’ll propose it.
Do I need permits to repipe?
Significant supply replacement is permitted plumbing work — DOB filings by a Licensed Master Plumber, inspections, and sign-off. That paper trail is part of the product: unpermitted plumbing surfaces at sale time, and a documented repipe is a selling point instead of a closing-table problem.
