North Hills Structural Work Around the Chimney
A brick chimney checked first, then tied, cut down or removed: North Hills structural work after a fire, engineered and permitted through LADBS.
If a North Hills house has a brick chimney, we probe its mortar joints ahead of pricing anything else. Heat from a fire inside the house, or close by, can soften mortar and open cracks where the chimney passes the roofline. We scrape a few joints, look for a gap between the masonry and the wall framing, and check for steel straps tying the chimney to the house. Those readings tell the engineer what the chimney needs.
Repair, brace or take it down
An unreinforced chimney is heavy and stiff, and in an earthquake it can crack loose from the house it stands beside. After a fire, the engineer weighs the options. A sound chimney may be repointed and tied to the floor and roof framing with steel straps. A damaged upper section can come down to the roofline or the firebox, with a framed chase and a listed metal flue built above. A chimney past saving is removed, and the wall framing behind it is closed in. Whichever path applies is priced as a separate item.
Clearances, framing and plan check at LADBS
Wood framing near a chimney keeps a set clearance from the masonry, and a fire repair is a chance to confirm it, since charring sometimes starts where a joist was set too close. New framing around the chimney follows the engineer's details, with blocking where straps attach. LADBS reviews the chimney work with the rest of the structural repair for a North Hills address, then inspects straps and framing before any finish hides them. Floors and walls elsewhere in the house get their own measurements, and anything soft or out of level joins the same scope.

Structural Work in North Hills: questions
Measured readings make the answer firm. We run a long level across each floor, check doors and windows for square, and push an awl into the sill and joist ends wherever water from the fire hoses ran. Masonry gets its own look for cracks and loose mortar. Those numbers, logged room by room, are what the engineer designs from.
A chimney that needs bracing or partial rebuilding is engineered work, as is any repair to a beam, post, footing or braced wall. Repointing mortar and patching a scorched stud of the same size usually is not. The engineer's chimney and framing details travel with the North Hills permit application, and you learn which items need them before any price.
Straps can join the chimney to the house while the framing beside it is exposed. They fasten masonry to the floor and roof framing at each level, and hold-downs and sill anchors are added wherever the engineer places plywood shear panels on the open walls. An inspector signs off each strap and anchor before it disappears behind drywall.
