Chimney Flue & Vent Installation
Every combustion appliance — fireplace, stove, insert, water heater sharing a chase — needs an exhaust path sized and routed for how it actually burns. An oversized flue breeds creosote; an undersized one chokes the fire. Most “smoky fireplace” complaints are sizing stories.
Sized by arithmetic, not habit
Flue sizing follows the appliance: firebox opening area, BTU rating, vent type, and run length all feed the calculation. We do the math, then route the system — clearances to combustibles, correct rise, sealed joints, proper termination height above the roofline — so it drafts on paper before it drafts in your living room.
Direct vent, B-vent, and everything between
Gas appliances bring their own alphabet: direct-vent systems that seal combustion entirely from room air, B-vent for draft-hood appliances, and flexible aluminum for some conversions. Each has its own clearance and termination rules — we install all of them and pull the right spec for yours, not the one that’s on the truck.
The Chimney Visit
- Appliance-based sizing calculation
- Class A, direct-vent, and B-vent systems
- Clearance-compliant routing through the structure
- Sealed joints and storm collar at penetrations
- Code-height termination with cap
Common Questions
Can two appliances share one flue?
Sometimes (two gas appliances with the right common-vent math), often not (never wood + anything). It’s a code calculation, not a preference — we run it and show you.
Why does termination height matter so much?
Draft is driven by the column and ruined by rooflines: terminate too low and pressure zones around the roof shove exhaust back down. The 10-foot/2-foot rule exists because physics doesn’t negotiate.
