Older homes here often need first-time creosote removal, smoke chamber parging, and tuckpointing of failed lime mortar joints.. Central San Diego's older Mission Hills, Kensington, and North Park chimneys often have no cap at all — original 1920s-50s construction predates modern cap requirements.
Do I really need a chimney cap?
Yes. CalFire requires spark arresters on chimneys in fire severity zones — and most of inland San Diego County qualifies. A cap also keeps rain out (preventing flue and crown damage), keeps animals out (preventing nests, smoke backups, and dead-animal odors), and improves draft. Caps are the cheapest insurance you can buy for a chimney.
What is the spark arrester requirement?
California Building Code requires a spark arrester on any chimney serving solid fuel in a Wildland-Urban Interface zone. The mesh must be 12-gauge or heavier with openings 3/8" minimum and 1/2" maximum. All our caps meet this code by default.
