There are approximately 40 million masonry chimneys in North America and the most common problem with these structures is water penetration due to missing or damaged Chimney Caps. Water causes over a billion dollars in damages annually in the form of staining, loss of insulation value, freeze-thaw damage, deterioration, and ultimately structural failure.
Animals see an uncapped chimney as an open invitation to move in. These unwanted guests can cause a multitude of problems. The installation of a chimney cap will keep these problems at bay.
More chimney damage is caused by moisture than any other source. Rain causes premature deterioration to the chimney interior and can damage metal fireboxes and dampers. Moisture will erode flue tiles, mortar joints causing crumbling, cracks, and blockages. Installing a chimney cap will stop these costly problems.
