Chimney Leaks & Storm Damage for Baldwin Hills Homeowners

Baldwin Hills is where our trucks start each morning, and the chimneys here shaped how we work. The neighbourhood went up in waves between the late 1920s and the 1950s, which means two very different systems sitting a few streets apart. The older Spanish Revival and period-revival houses along the slopes carry substantial unreinforced masonry stacks, frequently with original clay tile liners that have been through every significant shake this basin has produced since. The mid-century houses below them tend toward smaller fireboxes, shallower flues, and a great many gas conversions done at some point in the last forty years, not all of them done well. On top of that, this is hill terrain. The bluffs above Kenneth Hahn sit in a mapped fire hazard severity zone, which makes an approved spark arrestor a compliance question rather than an optional extra, and the grade means water that gets into a stack has somewhere to travel.

Late-1920s to 1950s period revival on the slopes with unreinforced masonry stacks and original clay tile, mid-century houses below with smaller fireboxes and many older gas conversions, and mapped fire hazard zone terrain along the bluffs.

A chimney is the only part of a roof that is deliberately full of holes, and Los Angeles tests that arrangement in a punishing way. Months of dry heat open joints and shrink sealant, and then a season's rain arrives inside a few atmospheric river systems, hitting masonry that has had no chance to acclimatise. Water gets in at four places: a cracked crown, failed flashing where the stack passes through the roof, a missing or damaged cap, and brickwork that has become porous enough to drink. The difficulty is that the stain inside the house rarely appears under the actual entry point — water tracks down the outside of the flue and shows up a storey below, in a different room. Sealing where the stain is achieves nothing, which is why people end up paying for the same leak three times. Finding it properly means getting on the roof and testing, not guessing from the ceiling.
