Poorly designed or outdated construction can lead to several different chimney problems from the top/crown all the way down to the bottom/roof line!
Wood is NOT the answer!
The problems with wood siding have been well documented. Not only does it need routine maintenance (painting/staining) – but eventually it will rot!
Whichever siding material is to be installed, a ‘house-wrap’ should be installed over the wood/sheathing (typically plywood) and behind the exterior siding. In all cases, the house wrap is the last line of defense in stopping incoming water or exterior water condensation. Tyvek® is the original house-wrap, incorporating unique material science that helps keep air and water out, while letting water vapor escape. It’s a house wrap engineered to keep homes cool in the summer, warm in the winter, and dry all year round!
Composite Siding & Trim
James Hardie fiber cement siding is specifically formulated to better resist damage from the elements (moisture, freezing temperatures, humidity, pests and fire) that pose threats to wood-based products. Wood may split, crack and deteriorate over time, while James Hardie siding resists weather damage and keeps its shape for a much longer time, which means less maintenance to worry about year after year.
The solution for replacing rotten wood trim is MiraTEC Composite Trim. The authentic woodgrain texture looks like wood but at the same time resists moisture, rot and termites!
The crown is the cement part on top of the chimney that keeps the rain from going into the structure below. The crown catches more sun, wind and rain than the rest of the chimney and with that being said, forming and pouring a new 4” thick concrete crown will last for a LONG time!
Step & Counter Flashing
The aluminum step and counter flashing on a chimney is often done incorrectly and sometimes just re-used when a roof is replaced (not a good idea!) Replacing the existing step flashing and cutting the counter flashing INTO the brick/mortar will ensure a leak-free chimney for a LONG time!
Chimney leaks are more common than you might think. Spalling describes the chipping off or loss of surface from a masonry material. Tuckpointing restores the masonry mortar joints between your bricks to eliminate water intrusion, prevent structural compromise, and restores the integrity & aesthetic value of your chimney. Sometimes it may be just as easy to dismantle and rebuild the chimney from the roof line up!
