With spring in full bloom and the struggles of shoveling 28 inches of snow as a dull memory, the most popular repair for chimneys this time of year is stucco resurfacing. After a long and cold winter, the freeze thaw effect takes its toll on any masonry structure. If a chimney has any type of small crack or defect in its surface, it has the ability to wick water inside of it’s mass. When enough water is absorbed and the air drops to freezing temperatures it tends to pop or delaminate the face of a brick, cinder block, and or stucco finish. This is usually when a homeowner notices pieces of brick or stucco laying on their roof shingles in the area of the chimney.
