These fireplace systems are prefabricated “kits” that allow builders to install a fireplace and chimney in a house for much less expense than a standard brick and mortar chimney system. There are thousands of these systems that have been installed in Portland, Tigard, Milwaukie, Oregon City, Beaverton and surrounding areas. A chimney sweep will perform approximately 10 to 20 % of his cleanings on these systems. The “zero” means that the system can be installed very close to combustible materials safely, without a danger of causing a structural fire. Cleaning and inspecting these systems is similar to cleaning a brick and mortar chimney, and the same inspection procedure is performed.

Repairs on a zero-clearance system are handled differently than a chimney repair on a brick and mortar system.
