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.

About this service

A chimney sweep is a professional who cleans the chimney flue to remove creosote, a flammable byproduct of burning wood. You should have this done annually if you use your fireplace regularly. If you hear scratching noises, see debris in the firebox, or notice smoke staying in the room, it is time for a visit. We use specialized tools to scrub the walls of the flue, ensuring your chimney draws air correctly and stays safe.

Summer is the best time to inspect your chimney while the weather is clear. We can easily spot structural issues, loose mortar, or cap damage that might have gone unnoticed during the winter. Getting your chimney serviced now means you are fully prepared for the first cold snap of autumn. Give us a call to book your inspection.
