Restorations & Re-Builds
Site Inspection Required for Pricing
Many older chimneys are in need of relining, especially when having a new stove or fireplace insert installed. It may be that you are able to smell smoke in other areas of the house, or the flue is full of tar and soot. Even though every flue is different, we can supply and fit the lining which best suits your chimney.
We also provide complete chimney relining, restoration, repair, as well as removal of old and/or unsafe chimneys.
Chimney Crown/Top Wash Repairs
The chimney crown (also referred to as the chimney wash or Top Wash) is the top element of a masonry chimney. It covers and seals the top of the chimney from the flue liner(s) to the chimney edge. It seals the chimney top opening around the flue and sheds rainwater which prevents moisture from deteriorating the chimney. For the chimney crown to fulfill its purpose, it must be properly shaped and installed.
Most masonry chimneys are built with a crown constructed from common mortar mix, the same mixture used to lay the bricks of the chimney. This mortar is not designed for, and will not withstand years of weather abuse without cracking, chipping or deteriorating – situations that allow water to penetrate the chimney. In fact, most sand and mortar crowns crack almost immediately after installation because of shrinkage.
A proper chimney crown should be constructed of a Portland cement-based mixture and cast or formed so it provides an overhang, or drip edge, projecting beyond all sides of the chimney by a minimum of two inches.
The flue liner tile(s) should project above the crown a minimum of two inches. The crown should provide a downward slope that will direct the water from the flue to the edge of the crown.
The 2″ over-hanging drip edge, by directing the run-off from the crown away from the sides of the chimney, helps prevent erosion of the brick and mortar in the chimney’s vertical surfaces. This can be poured in place on top of the chimney or precast on the ground and lifted into place.
