What the climate does to chimney sweep in Sherman Oaks
Valley summers bake a flat mortar crown until it checks and splits, and the first winter storm pushes water into the brick below it. We reseal hairline cracks and repour crowns that have cracked through, with a slope and a drip edge so water leaves the stack. That's why it drives our timing recommendations, the materials we choose, and what we flag in the written report once the visit wraps up.
