Chimney Cap & Crown Repair for Running Springs Homeowners

Running Springs sits at about 6,100 feet where Highway 18 meets Highway 330, and it is a genuinely year-round mountain town rather than a weekend one. The proportion of permanent residents is high, the burning season is longer than it is further down the rim, and a substantial number of households here use a wood stove or an insert as real primary or backup heat rather than as an occasional evening fire. That changes the work considerably. A stove that runs daily from October through April puts far more through the flue than an open fireplace lit twenty times a winter, and the flues serving inserts are frequently the original fireplace flue with an appliance dropped into it and no properly sized liner run to the top. That combination — heavy continuous use and an oversized, uninsulated flue — produces more glazed creosote and more genuine chimney fires than anything else we deal with on the mountain.

Wood stove and fireplace insert installations dominate the work here, and the most common serious finding is an insert vented into an unlined original fireplace flue. Manufacturers require a correctly sized liner run continuously to the cap, and a great many local installations do not have one — the appliance was simply set into the opening. Daily-burn households also need a different service interval to the rest of the rim: once a season is a starting point, and heavy burners are often better served by a mid-season check. Elevation means the season starts earlier and finishes later here than in Crestline or Blue Jay.

Almost every expensive chimney problem starts as a cheap one at the top. The crown is the sloped masonry slab that sheds water off the chimney's shoulders; when it cracks — and thin, unreinforced mortar-wash crowns crack early — water runs into the brick and the flue instead of off them. Freeze-thaw then does the rest, spalling brick faces, washing out mortar joints and separating tile. A missing cap adds direct rain into the flue, plus birds, squirrels and nesting debris that block it outright. Replacing a cap and sealing a crown is the least costly work on the chimney; a rebuild caused by ten years of skipping it is among the most expensive.
