Chimney Sweep Cost

A standard wood-burning fireplace sweep runs $155 to $195. Gas fireplaces cost less to service, $80 to $150, since they do not produce creosote. Enter your fireplace type and condition in the calculator above for a specific number.

At least once a year for a wood-burning fireplace or stove used regularly, which is the standard recommendation across the chimney and fireplace industry. A fireplace used only occasionally can sometimes stretch longer, but an annual inspection at minimum is still the safe default.

A level 1 inspection is a visual check of the readily accessible parts of the chimney and flue, usually paired with a routine sweep. A level 2 adds a video camera scan of the entire flue and is typically required after a chimney fire, before a home sale, or after a change in the appliance connected to the chimney. A level 3, which can involve opening walls, is rare and priced on its own outside a typical sweep.

First-degree creosote is light, dusty, and flaky, the normal result of routine burning. Second-degree is harder and more difficult to remove. Third-degree is a glazed, tar-like coating that forms from slow, smoldering fires, and it requires a chemical treatment before a standard sweep can safely proceed.

It does not produce creosote, so it does not need a traditional sweep, but the venting, burner, and pilot assembly still need periodic checking. That is why gas fireplace service costs less but is not free.
