This chimney was cracked, loose and crumbling due to extensive saturation decay to the brick masonry cells. During saturation, this chimney has gone through extensive expansion and contraction during freezing temperatures. These cracks can cause a leak into your home.
The state of this chimney was due to multiple factors, including: lack of a proper chimney cap and a lack of a water seal treatment. This chimney had become heavily saturated and the bricks and mortar joints have been extensively damaged due to the saturation decay. A proper chimney cap is one that shelters and protects the entire masonry crown footprint and all terminations, with a screen to keep our pests and debris.
A masonry chimney is a clay porous structure that absorbs water and becomes saturated in the PNW climate. In this saturated state, masonry decay is accelerated. It is regular exterior building maintenance to apply a water sealant to any masonry structure every 10 years. With this water seal application and the recommended repairs, we guarantee no leaking to occur. There was no masonry flue tile liner in this chimney. Without a flue tile liner, over time the emissions from the gas log set will break down the masonry in the flue.
Here are, after. We took this chimney down to just below the roofline, and rebuilt using new “Old Town Red” bricks. On top, we built a new crown with two 8″x16″ and one 8″x12″ flue tiles. We also supplied and installed new black roof and masonry counter flashing with ice and water shield. Due to the nature of cedar shake wood roofs, we did have some shake replacement as needed to properly flash this new chimney.
