Why Your Suffolk County Chimney Smells — and What Fixes It
A chimney smell in the house is one of the most common warm-weather complaints from Suffolk County homeowners. The cause is almost always creosote activated by summer heat, negative air pressure pulling flue odors down, or moisture causing a musty smell from mold or deteriorating mortar.
Creosote odor — annual cleaning removes the source
Summer backdraft smell — top-sealing damper seals flue from above
Musty smell — moisture from a failed crown or missing cap
Animal smell — nesting material in the flue
Chemical/gas smell — call 911 immediately

Frequently Asked Questions — Suffolk County Chimney Services
Why does my chimney smell in summer when I'm not using it?
Air-conditioned homes create negative pressure that draws air down the chimney — pulling creosote odors into the living space. A top-sealing damper stops this. Annual chimney cleaning removes the creosote causing the odor.
What does a creosote smell in the house mean?
Creosote odor means deposits inside the flue are being activated by heat and humidity. Annual cleaning removes the source.
My fireplace smells musty — is that a chimney problem?
A musty smell usually means moisture in the flue from a cracked crown, missing cap, or failed flashing. Have the crown, cap, and flashing inspected.
Why does my fireplace smell in summer even when I haven't used it?
Summer chimney odors are almost always one of two things: creosote activated by heat and humidity coming down an open damper, or animal debris in the flue. A top-sealing damper eliminates the open flue path that allows outside air — and odors — to enter. Annual cleaning removes the creosote source.
Why does my chimney smell like a campfire?
Campfire or wood-smoke smell from an unused fireplace means creosote deposits in the flue are off-gassing as temperatures rise. Annual cleaning removes Stage 1 and Stage 2 creosote before it becomes a persistent odor problem. A top-sealing damper prevents the chimney from acting as an intake during warm months.
Is chimney smell a safety hazard?
Creosote odor is unpleasant but not immediately dangerous when the fireplace isn't in use. Animal debris and nesting material in the flue creates both odor and a blockage risk — and should be removed before using the fireplace. Call DME Maintenance at 516-690-7471 to identify the source.
