What We Do
Our Plumbing Services
Every scope below is performed by licensed plumbers under our general contract, with DOB permits filed where required and all work pressure-tested before closeout.
Complete Plumbing System Replacement
Pre-war NYC buildings frequently contain galvanized steel supply lines and cast iron drain stacks that are 80–100+ years old. These corroded systems cause low water pressure, discolored water, frequent leaks, and eventual pipe failure. We replace entire plumbing systems with copper or PEX supply lines and PVC or cast iron drain piping — bringing your property into compliance with current NYC plumbing code. Full system replacement is typically performed during apartment or brownstone gut renovations when walls are already open.
Kitchen renovations require plumbing rough-ins for sinks, dishwashers, ice makers, pot fillers, and garbage disposals. We relocate supply and drain lines for new layouts, install proper venting, and connect gas lines for ranges and cooktops. All kitchen plumbing work is coordinated with other trades to maintain project schedules.
Bathroom renovations depend on reliable plumbing for showers, tubs, toilets, sinks, and heated floor systems. We rough-in new drain and supply lines, install mixing valves for temperature control, and connect all fixtures with proper shut-off valves and access panels. Our waterproofing coordination ensures drain connections are properly sealed before tile installation.
We install and replace all residential plumbing fixtures — toilets, sinks, faucets, showerheads, tubs, bidets, and water filtration systems. Fixture installation includes proper supply connections, drain sealing, and caulking for a finished, leak-free result.
Water Heater Installation
We install tankless and traditional tank water heaters sized appropriately for your property. For townhouses and brownstones with multiple bathrooms across several floors, we design recirculation systems that deliver hot water quickly at every fixture.
We locate and repair leaks in supply lines, drain pipes, and fixture connections. For concealed leaks causing water damage, we use non-invasive detection methods before opening walls, minimizing unnecessary demolition.
Gas Line Installation and Repair
We install and repair gas lines for cooking ranges, dryers, fireplaces, and outdoor grills. All gas work is performed by licensed technicians and inspected per DOB requirements.
Drain Cleaning and Sewer Line Service
We clear clogged drains in kitchens, bathrooms, and main sewer lines using professional equipment. For recurring issues, we inspect lines with cameras to identify root causes such as root intrusion, pipe collapse, or grease buildup.

Warning Signs
Signs Your Pipes Need Replacement
Galvanized steel supply lines and cast iron drain stacks in pre-war buildings corrode from the inside out. If you notice any of the following, schedule an assessment before a leak becomes water damage.
Low water pressure at multiple fixtures
Discolored or rusty water
Frequent leaks at joints and fixture connections
Visible corrosion on exposed supply lines
Water stains on ceilings or walls
Silver-colored galvanized supply pipes, likely 60–100+ years old
Stack access, vertical distribution, and building policies differ by property type. We work within each one — apartments, brownstones, and managed buildings.
Apartment Plumbing
Apartment plumbing in NYC involves working with shared stacks, coordinating water shutdowns through building management, and fitting modern fixtures within space constraints. Our experience with managed buildings means we know how to schedule stack tie-ins efficiently.
Brownstone and Townhouse Plumbing
Multi-floor brownstone and townhouse plumbing requires vertical distribution across 3–5 floors, proper sizing for simultaneous multi-fixture use, and coordination with structural work when routing new lines through existing framing.
Co-op and Condo Plumbing
Co-op and condo plumbing work requires building approval, scheduled access to shared infrastructure, and compliance with building-specific plumbing requirements. We coordinate all logistics with building management.
Supply, drain, and vent layout set during rough-in, while walls are open — the least expensive point to relocate fixtures.
