What affects the price

The final cost for your chimney service depends on a few specific factors. We look at the total height of the chimney stack, the level of creosote buildup inside the flue, and whether you have a standard masonry fireplace or a prefabricated metal insert. If there are structural blockages like nests or excessive debris that require extra labor, that will also adjust the estimate. We avoid hidden fees, but every setup is unique, so we evaluate the condition of your liner and firebox upon inspection.
