Greenpoint is the northernmost neighborhood in Brooklyn, bordered by Newtown Creek and the East River, with McCarren Park on its southern edge. Manhattan Avenue is the main shopping street, and the G train stops at Greenpoint Avenue and Nassau Avenue. Much of the housing is 19th and early 20th-century: two and three-story frame row houses, many with siding, brick walk-ups with storefronts, and handsome brick and brownstone blocks in the historic district. New high-rise buildings now line parts of the waterfront.

The older buildings have the plumbing problems you would expect from their age: cast iron and clay sewers, galvanized supply lines, and gas piping that has been extended many times. Small walk-ups with three to six apartments are common here, which puts many owners on the Local Law 152 inspection cycle. The new waterfront towers need building systems work like backflow testing and pump service.

Common plumbing issues in Greenpoint
Small walk-ups and gas shutoffs
A three to six unit building with a storefront is a classic Greenpoint building, and many still have old gas piping that has been added onto over the years. When a leak is reported, the utility can shut off gas to the whole building. We find and fix the leak, pressure test, file with the Department of Buildings and coordinate with National Grid to restore service.
Cold walls in frame houses
Frame row houses with siding hold heat less well than brick, and pipes in rear kitchen extensions, along outside walls or in unheated basements are the first to freeze. A split pipe often shows up only when it thaws and starts spraying. We repair burst pipes 24/7 and can move lines away from cold walls so it does not happen again.
Old sewers on low blocks
Blocks near Newtown Creek and the East River sit lower, and older clay and cast iron house sewers there can crack and settle. Add heavy rain and you get basement backups. A camera inspection shows the condition of your line, and a backwater valve can help keep street sewer water out.
Restaurants and bars on mixed-use blocks
Manhattan Avenue and Franklin Street have many restaurants and bars under apartments. Their grease and food waste go into building sewers that the upstairs tenants also depend on. When the line clogs, both back up. Regular jetting with our own van-mounted jetter keeps the line open, and we can set up a cleaning schedule with the owner.

Plumbing in Greenpoint: FAQ
Do small walk-ups in Greenpoint need Local Law 152 inspections?
Yes, if they have gas piping and three or more units. Only one and two family homes are exempt. The inspection is every four years on your community district's schedule and must be done by a licensed master plumber. We inspect, repair and file the GPS2 certification.
The gas was shut off in our building. Who do we call?
Call a licensed master plumber. We locate and repair the leak, pressure test the piping and file with the Department of Buildings. National Grid then inspects and restores gas. We handle the whole process and keep owners and tenants informed.
Can you replace galvanized pipes in an occupied building?
Yes. We can work one riser or one section at a time so most apartments keep water during the job, and we schedule shutoffs with the owner or super. You get a written estimate before any work starts.
