Chimney Extension in Brooklyn, NY
Safeguard Your Fireplace with Expert Chimney Extensions by King Chimney Masters
When your fireplace doesn’t draft properly, smoke fills your room, or your chimney isn’t up to code, the problem could be its height. In Brooklyn’s mix of historic brownstones, classic row houses, and modern homes, many chimneys are simply too short—or get left behind when rooftops are modified. That’s where King Chimney Masters comes in. Our chimney extension services restore safe operation, boost efficiency, and keep your home compliant with NYC building codes.
What Is a Chimney Extension and Why Might You Need One?
A chimney extension is the process of adding height to your existing chimney structure, usually by building up with matching bricks or installing a prefabricated flue extension. This isn’t just a cosmetic upgrade—chimney height directly affects how well your fireplace or wood stove draws smoke and gases safely outside.
Why does chimney height matter?
- Proper Draft: The taller the chimney, the more effectively it pulls smoke, gases, and fumes out of your home. If your chimney is too short, smoke can linger or flow back into your living space.
- Building Code Compliance: New York City and national codes require chimneys to extend a certain distance above the roofline for safety and function.
- Wind & Downdrafts: A chimney that’s too low can be affected by wind swirling off nearby roofs, leading to smoke blowback and poor performance.
New Construction or Additions: If you’ve added a second story, roof deck, or neighboring building rises higher than your chimney, you might need an extension to maintain safe airflow.
Signs You Need a Chimney Extension
Not sure if your home needs a chimney extension? Look for these common warning signs:
- Smoke Enters Your Home: If smoke blows back into the room when you use your fireplace, poor draft may be the culprit.
- Hard-to-Start or Low-Burning Fires: A short chimney can starve your fireplace of oxygen, making it hard to keep a fire burning.
- Recent Roof Work or Additions: If your roofline has changed or a neighbor’s building is now higher than your chimney, it may need to be raised.
- Constant Downdrafts or Unpleasant Odors: Wind patterns can push air down a short chimney, sending cold air and smells inside.
- Not Up to Code: NYC requires most chimneys to rise at least 3 feet above the highest point where the chimney passes through the roof, and 2 feet higher than any part of the building within 10 feet.
If you’re experiencing any of these issues, call King Chimney Masters for a thorough inspection and honest advice.
Our Chimney Extension Process
