What gas fireplace cleaning actually protects 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. A typical visit here covers pilot assembly and thermocouple cleaning, ceramic log inspection and repositioning, and burner port cleaning for even flame, scoped to what the chimney actually needs rather than a number quoted over the phone.
