What affects the price

Cleaning costs depend on a few specific things regarding your fireplace setup. We look at the total height of the chimney, the number of flues, and how much creosote buildup has accumulated over time. If your chimney has been neglected for several seasons, or if there are blockages like animal nests or heavy debris, the labor required increases. The type of liner and the fireplace architecture also play a role in the complexity of the service. Exact pricing confirmed free on the call.

We come out to inspect your flue, remove creosote buildup, and check for obstructions like bird nests. You should schedule this annually before the first cold snap of the season.
