Brownstones, Steam Heat & Cast Iron Since 1898

What We See in Brooklyn
Brooklyn's building stock is roughly 70% brownstones and row houses built between 1870-1940. These are 2-4 story buildings with shared walls, original cast iron drain stacks, galvanized water lines, and steam or hot water heating systems. The remaining 30% is a mix of pre-war apartment buildings, post-war mid-rises, and newer construction.
Common Plumbing Issues in Brooklyn
Brownstone Sewer Lines
Original terracotta sewer lines under brownstones crack and shift over 100+ years. Root intrusion from street trees is extremely common in Park Slope and Crown Heights.
Steam Heat Problems
Most Brooklyn brownstones run on steam heat. Banging radiators, failed air vents, and water hammer are the most common winter calls we get.
Galvanized Pipe Corrosion
Original galvanized water lines corrode from the inside over decades. Upper-floor apartments in brownstones often experience low water pressure as the pipe diameter shrinks.
Basement Flooding
Brooklyn basements flood during heavy rain when backflow preventers fail or sewer lines can't handle the volume. Garden-level apartments are especially vulnerable.

Read guideBrooklyn Plumbing FAQ
How much does it cost to re-pipe a Brooklyn brownstone?
Full copper re-piping of a typical 3-story Brooklyn brownstone runs $15,000-$35,000 depending on the number of bathrooms and kitchen locations. This replaces all galvanized water supply lines with copper (NYC code requires copper, not PEX).
My Brooklyn brownstone radiators are banging - what's wrong?
Banging radiators in Brooklyn brownstones are almost always caused by water hammer in steam heating systems. The radiator isn't pitched properly toward the supply valve, or the air vent is clogged/painted over. Both are fixable without replacing the radiator.
Do I need a plumbing permit for a Brooklyn brownstone renovation?
Yes, if you're moving any plumbing fixtures to new locations or doing any gas work. Cosmetic bathroom updates (new fixtures in existing locations) typically don't require permits. All permit work in NYC must be filed by a licensed Master Plumber.
How do I prevent my Brooklyn basement from flooding?
Install a backwater valve on your sewer line, ensure your sump pump works, and check that your sewer lateral isn't compromised. During heavy rain, NYC's combined sewer system can back up into basement-level drains.
Should I replace my brownstone's cast iron drain stack?
Not necessarily. Cast iron can last 100+ years if it's in good condition. Have it scoped with a camera first. If there are cracks, heavy scaling, or bellies, then replacement makes sense. Partial replacement (just the damaged section) is often possible.
