- Creosote
- Creosote is a dark, tar-like residue that forms inside your flue when wood burns incompletely. Because it is highly flammable, thick buildup is the leading cause of dangerous chimney fires in Cherry Hill Township. Our team uses specialized brushes to remove this hazard during every routine chimney sweep.
- Flue
- A flue is the vertical vertical channel inside your chimney that safely guides toxic smoke, gases, and sparks out of your living space and away from your roof. Keeping this pathway clear is vital for preventing deadly carbon monoxide leaks into bedrooms and living rooms.
- Flue liner
- A flue liner is a protective clay tile, metal, or cast-in-place barrier installed inside the flue. It shields your home framing from intense heat and corrosive combustion acids. Damaged liners violate fire codes and require immediate repair or relining by qualified technicians.
- Damper
- A damper is a metal valve located near the top of the firebox or inside the throat of the chimney. You open it to let smoke escape when burning wood and close it tightly when the fireplace is not in use to stop heated or cooled indoor air from escaping.
- Chimney crown
- The chimney crown is the solid concrete slab at the very top of your masonry structure. It seals the top against rain and melting snow, preventing water from soaking into the bricks and causing freeze-thaw damage during harsh New Jersey winters.
- Chimney cap
- A chimney cap is a metal hood with mesh screening installed over the flue outlet. It blocks rain, leaves, and wildlife like raccoons or birds from nesting inside your flue while allowing smoke to vent freely. Learn more about protecting your roof in our maintenance tips.
- Firebox
- The firebox is the open masonry enclosure where you actually build and burn your fires. Built with high-temperature firebricks and refractory mortar, it must withstand extreme heat without cracking and exposing surrounding wooden walls to dangerous flames.
- Smoke chamber
- The smoke chamber is the sloping transitional space located directly above the firebox and below the main flue. Its engineered geometry compresses smoke and funnels it smoothly upward so it does not spill back into your living room during a fire.
- Draft
- Draft refers to the natural upward flow of warm air and exhaust gases rising up the chimney. A strong draft pulls fresh air into your fire for clean burning, while a weak draft causes smoke to back up into the room due to cold air blockages.
- Spalling
- Spalling is a destructive masonry defect where brick faces pop, flake, or crumble away due to trapped moisture freezing and expanding. Left unaddressed, spalling structural bricks can compromise the entire stability of your chimney stack and lead to costly reconstruction.
- Tuckpointing
- Tuckpointing is the essential mason repair process of grinding out decayed exterior mortar joints and replacing them with fresh, durable mortar. This stops water infiltration, strengthens old brickwork, and keeps your chimney structurally sound through seasonal temperature shifts.
- Chimney flashing
- Chimney flashing is the overlapping metal shielding installed where your masonry cuts through the roof deck. Correctly sealed joints stop rainwater from seeping into your attic insulation, which avoids toxic mold, rotting timber, and costly ceiling repairs.
- Level 1 / Level 2 inspection
- A Level 1 inspection is a visual check of readily accessible areas during routine cleanings. A Level 2 inspection is more thorough, requiring specialized video cameras to check hidden flues inside walls after a property sale, a severe storm, or an unexplained chimney fire.
- CSIA certification
- CSIA certification is the gold standard credential awarded by the Chimney Safety Institute of America after rigorous testing. Certified sweeps understand complex building codes and fire safety standards, giving Cherry Hill Township homeowners complete peace of mind during service visits.
- Dryer vent cleaning
- Dryer vent cleaning is the specialized service of removing flammable lint buildup from your laundry exhaust ductwork. Scheduling this alongside your chimney sweep prevents residential dryer fires and lowers your monthly energy bills by helping appliances run efficiently.
