Does a Fireplace Add Resale Value in 2026?
DFW realtor data on wood, gas, and electric fireplaces. ROI by neighborhood and home price tier.
Most chimney fires don't start with a roaring blaze. They start with a layer of glazed creosote, a damper that was left half-open, and a Thanksgiving fire built with damp wood. Twelve years of inspections in DFW homes tells us the same story over and over — and the fix is almost always boring habits, not gear.
01Burn dry, seasoned hardwood (not whatever's stacked outside)
Wet wood is the single biggest creosote producer we see. Moisture content above 20% means the fire runs cool, smolders, and deposits tar instead of clean ash. Oak and hickory split and stacked for 12+ months under cover are ideal. If you can hear the wood sizzle when it burns, it's too wet.
02Get a Level 1 inspection every year — no exceptions
NFPA 211 calls for it. We find issues in roughly 1 in 4 annual inspections that the homeowner had no idea about: spider cracks in the crown, a cap missing after a storm, a flue tile that shifted half an inch. None of these are visible from the firebox.
03Sweep before stage-2 creosote builds up
Stage 1 creosote is a light, fluffy dust — easy to remove. Stage 2 is the granular black flakes most homeowners picture. Stage 3 is the dangerous one: a glassy, tar-like glaze that's nearly impossible to remove without rotary chain restoration. Most homes need a sweep every 70–80 burn-hours.
04Install a cap with mesh — and check it twice a year
A stainless steel cap with 3/4" mesh keeps out rain, animals, and most embers. Inspect from the ground with binoculars after major storms. If the mesh is dented or torn, schedule a replacement before nesting season starts.
05Use a CO detector on the same level as the fireplace
Carbon monoxide from a partially blocked flue is invisible and odorless. UL-2034 listed detectors with digital readouts are cheap insurance. Replace them every 7 years — the sensors degrade.
06Never leave a fire unattended overnight
Sounds obvious. We've responded to four house fires in the past five years that started with a 'small fire that should have burned down.' Embers can stay viable for 48+ hours. Use the damper and a tight-fitting screen.
07Keep combustibles 36 inches from the firebox opening
Couches, magazine racks, Christmas trees, holiday decor — all common ignition sources. The 36-inch rule is the NFPA standard. Marking the floor with painter's tape once at the start of the season is the easiest way to remember it.
None of these are expensive or technical. They're calendar items, habit changes, and one annual phone call. Most chimney fires we respond to could have been prevented by following 3 of these 7 — usually the boring ones.
