A chimney sweep will:
•check the firebox for damaged brick and missing or crumbling mortar. •open the damper completely to BE sure it moves freely and fits snugly against the smoke shelf. •USE a flashlight to check the damper for cracks. Pitting or RUSTED-OUT sections. (broken or corroded dampers should BE replaced. )
•look for ANY debris that MAY restrict AIR flow and remove it. •check for cracked. Damaged or voided flue tiles. (vertical cracking in the liner is a sure sign of a previous flue fire and is a serious problem that will need REPAIR. )
•CHECK and remove creosote deposits Greater than 1/8 inch thick. •inspecting smoke chamber for separations. Cracks or corbel voids. •inspect flashing around chimney casing. •inspection chimney CAP and crown wash and shoulders if present. •take photos of finds that DO NOT meet NFPA 211 code standards.
