Chimney Ventilation & Draft Repair

Poor draft has many causes, creosote buildup, blockages, an incorrectly sized or short flue, a missing cap, or negative air pressure in the home. We diagnose the real cause rather than guessing, then fix it: clearing blockages, adjusting the flue, or adding solutions like a properly sized cap or flue extension. The goal is a fireplace that drafts strongly and keeps smoke and carbon monoxide out of your home.

Why Ventilation Problems Are Serious

Poor venting can push smoke and carbon monoxide back into your home, which is a safety risk.

A chimney’s entire purpose is to draw smoke and combustion gases up and out of your home, and when that draft fails, the consequences go beyond annoyance. A fireplace that smokes into the room is a sign that dangerous gases, including odorless, potentially deadly carbon monoxide, may also be entering your living space. Draft problems can be caused by creosote buildup, animal nests, a missing or wrong-sized cap, a flue that is too short or improperly sized, or negative pressure created by tight modern homes. Because the causes vary, proper diagnosis is essential. Professional ventilation repair identifies the true source and corrects it, restoring a strong, safe draft so your fireplace works the way it should and keeps harmful gases out of your home.
