Chimney sweeping and creosote removal
Sweeping is the foundation of chimney safety, and it is the service most misunderstood in South Florida because so few homes burn wood regularly. The point of a sweep is not only creosote. It is removing anything in the flue that restricts airflow or can ignite — soot, glazed creosote, nesting material, leaf litter, crumbled mortar, fallen tile fragments and insect nests.
Creosote forms in three stages. First-degree creosote is a light, flaky soot that brushes away easily. Second-degree is a harder, flaky tar that needs aggressive brushing. Third-degree is a glassy black glaze, nearly impossible to remove by brush alone and extremely combustible — it is the material behind most chimney fires. We remove glazed deposits with rotary chain and whip systems rather than chemical treatment alone, because chemicals soften glaze but rarely clear it.
Our process: seal the fireplace opening, run a HEPA negative-air machine so the flue is under suction for the whole job, sweep from the appropriate direction for the flue type, vacuum the smoke shelf and firebox, then run a camera up the full length so you can see the result. If the sweep reveals a defect — a cracked tile, a missing mortar joint, a rusted damper — you get the photo before we pack up.
How often: after roughly one cord of wood burned, or annually for light users. Gas appliances still need annual flue evaluation because acidic condensate attacks masonry even without soot. Restaurants with wood ovens generally need quarterly service, sometimes monthly.
What drives cost: flue height and access, number of flues, degree of creosote buildup, and whether animal removal or obstruction clearing is needed.
