https://chimcheree.com/wp-content/uploads/slideshow-gallery/4G.jpg The mortar wash at the top of the chimney has previously been treated to minimize water penetration. The top course of brick is stepped in, creating a shelf that collects water. A concrete crown or full coverage chimney cap would be the best way to correct that problem.

This allows moisture produced in the chimney to escape, rather than being trapped inside the bricks. ChimneySaver is applied with a low pressure sprayer.

It’s amazing how a chimney changes over time. Because chimneys typically are not built to resist water penetration, the structure is affected by water from the start. Bricks and mortar absorb water, creating a hospitable environment for mold and moss. These minuscule growths slowly tear apart masonry. They also slowly make the chimney look dull and dingy and downright ugly.
This mold growth is usually obvious on most chimneys by the time they are 20 to 30 years old. Significant water damage is visible by 50 to 60 years old, and if your chimney is approaching 100 years, it probably needs significant work.
We recently addressed water penetration problems on a chimney that’s approximately 30 years old. Water was beginning to rust the wood stove insert in the fireplace, so we wanted to stop the water penetration before it caused more damage. We pressure washed the chimney to remove the mold before applying ChimneySaver Water Repellent. Click on the picture and look at the gallery. The transformation is pretty amazing.
If your chimney is looking ugly, give us a call. We can make it look pretty again.
