Services for Columbia Homes
Most of Columbia was built between the late 1960s and the 1990s, and that shows in its fireplaces and vents. Here is what we do for Columbia homeowners.
Air Duct Cleaning
Dust coming out of the vents, a recent renovation or a new pet are the usual reasons Columbia homeowners call us. Air duct cleaning starts at $99.
Dryer Vent Cleaning
Many Columbia townhouses vent the dryer through a long duct to the roof or a side wall, and long runs clog fast. We clean the full run to the outside hood for $69.
Chimney Cleaning
Older single-family homes in Wilde Lake, Harper’s Choice and Oakland Mills often have 40–50 year old masonry chimneys. A sweep is $199, with photos of the flue.
Chimney Repairs
Crowns, mortar joints, caps and flue tiles wear out with age. We start with a $49 inspection and show you photos of anything that needs repair.
Gas Fireplace Services
Townhouses and newer homes in River Hill and Kings Contrivance often have prefab or gas fireplaces. We inspect, clean and service them.

Signs it’s time to call: the fireplace smells smoky, the dryer needs two cycles to dry a load, the laundry room gets hot, or you see dust around the vents.
