Chimney Draft & Smoking Problems

A fireplace works on a simple principle: hot air rises, pulling smoke up the flue and drawing fresh air into the fire. When that draft is disrupted, smoke spills into the room instead. It's a frustrating problem — and it has a surprising number of possible causes, from flue sizing to house pressure to a simple blockage.

Frank & Sons diagnoses draft and smoking problems systematically. Rather than selling you a single fix and hoping, we identify which of the common causes is actually at work in your home, because the right correction depends entirely on the reason the draft is failing.

Symptoms of a draft problem

• Smoke rolls back into the room when you light a fire.
• The fire is sluggish or hard to keep going.
• You smell smoke or a campfire odor in the house.
• Downdrafts push cold air and odors down the chimney.
• The problem is worse on windy days or when the furnace runs.

Diagnosing the cause

Common causes include a flue that's too short or improperly sized, a blockage (creosote, debris, or animal nests), a missing or damaged cap, competition from exhaust fans and HVAC that depressurize the house, and cold flues that won't establish an updraft. Each has a different remedy.

We work through the possibilities — checking flue dimensions, clearing blockages, examining the cap and crown, and considering how the house itself affects draft — then recommend the specific correction. Sometimes it's as simple as a sweep; sometimes it calls for a cap change or flue modification.
