Fireplace Inspection in Calabasas, CA

Why most fireplace calls here end up being water calls

Nobody tells you the crown is mortar. Builders often troweled leftover brick mortar flat on top. It wicks, freezes, and splits along the flue tile. Look up from the yard with binoculars. A dark stain streaking one face means the crown already lost.

Chase-top metal on sided chimneys rusts at the seam first. Those boxed-out framed chases hold prefab units. Rust bleeds orange down the siding below. That streak is visible from the sidewalk.

Inside, the tell is a damper that will not seat. Rust welds the plate to the frame. Then you smell wet ash in humid weather. People blame the chimney. It is a lid problem.

Prefab panels crack at the back vertical seam. Run a fingernail across it. If the nail catches, the panel is done. Only the manufacturer's listed panel goes back in. That means finding the label plate on the firebox rail. Remodelers paint it over constantly.

Scratch a mortar joint in the smoke chamber with a key. Sandy joints mean water has been working a while. Corbelled brick ledges there hold creosote a brush skips. We look at lintel bearing and hearth extension depth as separate items. They fail for separate reasons.
