- Creosote
- A tar-like, highly flammable residue that builds up inside a chimney flue as wood smoke cools and condenses. Heavy creosote is the leading cause of chimney fires, which is why annual sweeping matters. Anthony Brown Chimney Inc is glad to explain how this affects your Hermitage home during a free estimate.
- Flue
- The vertical passage inside a chimney that carries smoke, gases, and combustion byproducts safely up and out of the home. If it shows up on your quote, Anthony Brown Chimney Inc will walk you through it in plain language.
- Flue liner
- A protective inner layer (clay tile, metal, or cast-in-place) inside the flue that contains heat and corrosive byproducts, protecting the surrounding masonry and improving draft. Anthony Brown Chimney Inc is glad to explain how this affects your Hermitage home during a free estimate.
- Damper
- A movable metal plate that opens to let smoke escape during a fire and closes to stop heated or cooled air from leaking out when the fireplace isn't in use. Our technicians point terms like this out to Hermitage homeowners as part of the work we do.
- Chimney crown
- The sloped concrete slab at the very top of the chimney that sheds rainwater away from the flue and masonry to prevent water damage. Our technicians point terms like this out to Hermitage homeowners as part of the work we do.
- Chimney cap
- A metal cover with mesh sides fitted over the flue opening that keeps out rain, animals, and debris while acting as a spark arrestor. If it shows up on your quote, Anthony Brown Chimney Inc will walk you through it in plain language.
- Firebox
- The chamber where the fire actually burns, built from heat-resistant firebrick and refractory mortar to withstand extreme temperatures. Our technicians point terms like this out to Hermitage homeowners as part of the work we do.
- Smoke chamber
- The angled area just above the firebox that funnels smoke from the wide fireplace opening up into the narrower flue. Anthony Brown Chimney Inc is glad to explain how this affects your Hermitage home during a free estimate.
- Draft
- The upward flow of air that pulls smoke and gases out through the chimney; poor draft lets smoke spill back into the room.
- Spalling
- Flaking, chipping, or crumbling of brick caused by trapped moisture freezing and thawing — a sign the masonry needs repair before it worsens. If it shows up on your quote, Anthony Brown Chimney Inc will walk you through it in plain language.
- Tuckpointing
- Grinding out deteriorated mortar joints and refilling them with fresh mortar to restore the strength and weather-resistance of the masonry. Anthony Brown Chimney Inc is glad to explain how this affects your Hermitage home during a free estimate.
- Chimney flashing
- The metal sheeting that seals the joint where the chimney meets the roof, preventing water from leaking into the home along that gap.
- Level 1 / Level 2 inspection
- Standardized inspection tiers from the NFPA: Level 1 is a basic visual check of accessible areas; Level 2 adds a video scan of the flue and is required after chimney changes, property sales, or a chimney fire. Anthony Brown Chimney Inc is glad to explain how this affects your Hermitage home during a free estimate.
- CSIA certification
- Credentialing from the Chimney Safety Institute of America, indicating a technician has passed a national exam on chimney and venting safety. Our technicians point terms like this out to Hermitage homeowners as part of the work we do.
