Flue Extension Installation: Trust Us for Quality Protection

When your Air Flow drafting properly — or when new construction, roofline changes, or code requirements leave your flue too short — a flue extension is the safest and most effective solution. Installed correctly, it ensures smoke, gases, and sparks exit your home safely while protecting your chimney from long-term damage.

Air Flow Flue Extension Failing?

Just like other parts of your flow system, flue extensions are exposed to constant weathering, heat, and stress. Over time, even the most durable extension can begin to fail — and when it does, it impacts both safety and performance.

Signs Your Flue Extension May Be Failing

  • Visible Rust or Corrosion
    Stainless steel extensions that once looked solid may show rust streaks, pitting, or discoloration.

  • Loose or Wobbly Connection
    If the extension no longer feels secure at the top of the flue, it may allow water or gases to escape.

  • Cracked or Damaged Masonry
    For masonry extensions, shifting or cracking bricks can weaken draft and invite leaks.

  • Smoke or Draft Problems
    Smoke backing into the home, increased creosote, or persistent downdrafts can point to a failing or improperly sized extension.

  • Water Leaks
    Stains around the chimney or moisture inside the flue may indicate gaps or failed seals at the extension joint.
