Brooklyn Plumber, Heating & HVAC

Licensed Master Plumber Serving All of Brooklyn

Karl's Plumbing Heating & Cooling has served Brooklyn property owners since 1935 — four generations of Licensed Master Plumbers who understand the unique plumbing and heating challenges of Brooklyn's diverse building stock. From the brownstone-lined streets of Park Slope and Cobble Hill to the apartment towers of Downtown Brooklyn and the residential neighborhoods of Bay Ridge and Flatbush, our team delivers dependable plumbing, heating, and HVAC service across the entire borough.

Brooklyn's buildings are architecturally diverse and often old. Pre-war brownstones with original cast iron waste lines, row houses with galvanized supply pipes, and apartment buildings with steam heating systems all require a Licensed Master Plumber who has seen these systems before. Karl's Licensed Master Plumbers Brian Karl (DOB License #921) and Chris Deifel (DOB License #2060) have worked on thousands of Brooklyn properties and bring that experience to every job.

Brooklyn Neighborhoods We Serve

North Brooklyn: Williamsburg, Greenpoint, Bushwick, and Bedford-Stuyvesant. These neighborhoods have experienced significant development alongside their historic housing stock. We work on both renovated brownstones and new construction.

Brooklyn Heights & Downtown: Brooklyn Heights, DUMBO, Boerum Hill, Cobble Hill, Carroll Gardens, Red Hook, and Downtown Brooklyn. Some of New York City's oldest and most valuable brownstones are here, with plumbing and heating systems that demand experienced care.

Park Slope & Prospect Park Area: Park Slope, Prospect Heights, Crown Heights, Prospect Lefferts Gardens, and Windsor Terrace. These neighborhoods are dominated by landmarked brownstones and multi-family row houses with shared heating systems and aging pipe infrastructure.

South Brooklyn: Bay Ridge, Dyker Heights, Bensonhurst, Borough Park, Sunset Park, and Bath Beach. South Brooklyn has a mix of single-family homes, two- and three-family houses, and small apartment buildings — many with oil-fired boilers that are prime candidates for oil-to-gas conversion.

East & Southeast Brooklyn: Flatbush, East Flatbush, Canarsie, East New York, Brownsville, and Sheepshead Bay. Diverse residential neighborhoods with a range of building ages and construction types.

Southern Waterfront: Brighton Beach, Coney Island, Manhattan Beach, and Gravesend. Coastal proximity means salt air corrosion can accelerate pipe deterioration — something we address with appropriate materials and protective measures.

Plumbing Services in Brooklyn

Brooklyn plumbing is our bread and butter.

Heating & Boiler Services in Brooklyn

Brooklyn's older buildings depend heavily on boiler-based heating — steam systems in pre-war brownstones and hot water systems in mid-century apartment buildings. Karl's has maintained, repaired, and replaced boilers in Brooklyn for nearly 90 years.

Drain & Sewer Services in Brooklyn

Brooklyn's sewer system includes some of the oldest infrastructure in the city, and tree root intrusion from the borough's mature street trees is a persistent problem. Karl's provides:

  • Drain Cleaning — Kitchen, bathroom, and main drain line clearing for Brooklyn homes and restaurants

  • Rooftop Units — RTU installation and repair for Brooklyn commercial buildings
  • AC Installation & Replacement — Central AC, split systems, and through-wall installations

What plumbing issues are common in Brooklyn brownstones?

Brooklyn brownstones commonly have aging cast iron waste stacks, galvanized supply pipes that restrict water flow, and steam boilers that need regular maintenance. Tree roots from Brooklyn's street trees frequently infiltrate sewer lines. These are all issues we deal with daily.

Do you handle oil-to-gas conversions in Brooklyn?

Yes. Many Brooklyn buildings, especially in South Brooklyn and Flatbush, still use oil-fired boilers. We handle the full conversion including oil tank removal, new gas boiler installation, and all DOB and DEP permits. See our oil-to-gas conversion guide for more details.
