The Chimney Sweep Process:
Depending on how many floors you have, how big your fireplace is and how dirty it may be, as well as how prepared the area is will depend on how long the process will take. A sweep with an inspection could take anywhere from 30 minutes to 1 ½ hours.
When your chimney sweep arrives, it would be time saving if you have removed everything out from in front of the fireplace including rugs, and any decorations off of the mantle, as well as moving any outdoor furniture or planters away from the area that the sweeps will be placing their ladders to gain access to the chimney from. They will put on booties wear a mask and will begin by covering any nearby furniture and floors, if there are two sweeps one will access the roof and the other will bring in a HEPA certified ash vacuum. The vacuum nozzle will be placed in the smoke chamber by the smoke shelf so the ash, soot and creosote that is being pushed down by the sweep on the roof will not enter into your home. Once the sweep on the roof is finished brooming the flue he will begin the inspection of the outside portion of the chimney, they will be looking for cracked bricks and crumbling mortar, efflorescence (a discoloration that signifies moisture problems) and cracks in the crown.
The technician on the inside will be cleaning the inside portion of the flue and fireplace until it is free of any ash, soot or creosote once clean the technician will then begin the inspection of the inside aspects of the fireplace
