Professional Chimney Downdraft Repair Services | Bob's Chimney
A downdraft repair forces smoke, cold air, and harmful gases back into your home instead of venting them outside. At Bob’s Chimney, we provide expert downdraft solutions to restore proper airflow, eliminate smoke infiltration, and keep your fireplace operating safely.
Why Does Chimney Downdraft Happen?
Downdrafts occur when air pressure imbalances or structural issues reverse the chimney’s natural draft. Common causes include:
Negative Air Pressure – Tightly sealed homes or competing exhaust fans (like HVAC or kitchen vents) pull air backward.
Poor Chimney Height – A short chimney doesn’t create enough draft to overcome wind pressure.
Blockages or Creosote Buildup – Debris, nests, or thick creosote disrupt airflow.
Improper Flue Sizing – An oversized or undersized flue fails to maintain consistent draft.
Wind Turbulence – Nearby trees, tall buildings, or roof peaks deflect wind downward.
Signs You Have a Downdraft Problem
