Chimney Fire Safety Tips for Maryland Winters

Most chimney fires are not accidents of fate. They are the end of a chain — wet wood, heavy creosote, a skipped inspection — that can be broken at any link. Here is the checklist we give our own families before the Maryland burn season.

Start the season clean

An annual inspection and a sweep when deposits reach 1/8 inch is the whole foundation. Creosote is fuel stored inside your exhaust system; the sweep removes the fuel before it ever meets a spark.

Burn dry, seasoned hardwood

Wood should be split, stacked and dried for six to twelve months — under 20% moisture. Wet and green wood burns cooler and dirtier, laying down creosote several times faster and smoking out the neighborhood in the bargain.

Build hot, small fires

Hot fires burn cleaner. Smoldering, damped-down fires are creosote factories. Burn briskly, avoid overnight smoldering, and let the flue fully warm before settling the fire in.

Know the sound of a chimney fire

A chimney fire often announces itself: a loud roaring like a freight train or jet, dense smoke, an intense smell, and sometimes flames or sparks from the top of the stack. If it happens: get everyone out, call 911, and do not use the fireplace again until a Level 2 inspection has cleared it — fires crack liners invisibly.

Keep the hearth zone clear

Three feet around the fireplace: no wood piles against the box, no rugs, no holiday stockings within ember range while burning. Use a screen or glass doors, and never leave a fire unattended overnight.

Ashes are not inert

Ash holds live coals for days. Metal container, tight lid, stored outside away from the house and deck — never a paper bag in the garage.

Detectors are the last line

Working smoke and carbon monoxide detectors on every level, tested monthly. A damaged flue can leak CO silently; the detector is what makes it loud.

Winter in Maryland is burning season. A clean flue, dry wood and a sound liner turn it into the safest heat in the house — and all three start with one inspection.
