Project Description


Extending your chimney isn’t just about convenience. It can also be the law. According to New York City’s building code, a chimney has to extend at least two feet above the highest construction within ten feet of it, even if it isn’t part of the same building. That could mean the roof ridge, a nearby antenna, or even the place next door. And if it doesn’t pass inspection, you’re in for a big headache.

Your chimney does more than carry smoke outside: it keeps allergens, dust, and other contaminants from getting inside too. If you’re seeing too much smoke from your fireplace, or you’re noticing pollen and soot building up inside your home, your chimney may need an extension.

Do You Need a Chimney Extension?

Here are just some of the situations that might call for a chimney extension:

Even if you haven’t made any changes to your home or business, the building codes can always change in a way that means you’ll have to extend your chimney. It’s worth keeping up with the law and staying ahead of the next inspection if it means avoiding hefty fines and other penalties.

If you change how you use your chimney, you might need an extension. As a rule, it should be taller than the building and wide enough to avoid a downdraft, which can depend on the temperature. If there isn’t enough pressure in the chimney, the outside pressure can push the smoke right back inside.

By the same token, without enough interior pressure, anything on the outside, whether it’s mold, pollen, or humidity, can make its way down through the chimney and into your building. Chimney extensions create extra space to build up pressure, which keeps the smoke outside where it belongs.

    How Will Chimney Professionals Extend Your Chimney?

    An initial inspection will help us determine whether your chimney needs an extension. If it does, we’ll provide you with an accurate estimate and let you know how long the extension will take.

    We’ll start by precisely measuring your chimney to make sure we install a flue liner that’s a perfect fit. These measurements will also help us plan the extension by ensuring that we obtain the right materials to match your chimney’s unique size and construction. We can easily match the brick, concrete, or any other materials of your existing chimney to ensure a seamless modification.

    Once the extension’s complete, we’ll install a new crown on top of your chimney to leave you with a chimney that performs better and meets all necessary building code regulations.

    • Assessment: Conduct a thorough inspection of the chimney and its surroundings.

    • Customized Solutions: Propose an extension tailored to your chimney’s specific needs.

    • Material Matching: Use materials that match or complement the chimney’s structure.

    • Safety Protocols: Adhere to safety standards and guidelines throughout the extension process to ensure that your chimney continues to function safely and efficiently afterwards.

    • Height Adjustment: Increase the chimney height to improve airflow and prevent downdrafts.

    • Sealing and Insulation: Ensure that your newly extended chimney is well-sealed and insulated in order to prevent heat loss and protect it from weather and contaminants.

    • Inspection: Perform a final inspection to ensure the work meets quality and safety standards.

    • Maintenance Tips: Offer guidance on maintaining your chimney’s optimal performance.
