Started the business in '99 when I realised the magnitude of shoddy work occurring in home constgruction in the Atlanta, Ga. Metro area. Whether your fireplace is brick or prefab I can service it. After sweeping the flue I run a camera up the flue to verify that the brick chimney flue sections are in need of replacing or that the sheet metal flue of the prefab unit is still intact. Additionally there is the problem of the high efficiency furnaces. Actually the problem is the water heater venting into the old furnace flue and there isn't enough heat available to draw the exhaust gases out of the flue. Soon the carbon monoxide detector is going off. Call me!
