Chimney Repair in Manhattan Beach

The California Residential Code requires a chimney to stand at least 3 feet above where it passes through the roof and 2 feet above anything within 10 feet. Raise the roof around an existing chimney and the old top may end up too short, or even below the new roofline.

Extending a masonry stack means checking that the base can carry the added weight and height; often a lighter metal flue extension or a framed chase on top is the better answer. The City of Manhattan Beach building department decides what the extension needs as part of the remodel's permit.

Not every chimney is worth repairing. If the fireplace will be converted to gas or removed, the options are to repair the stack for a gas insert, to cap and seal it as a decorative feature, or to take it down below the roofline and close the roof.

A heavy brick chimney nobody plans to use still has to stand safely through an earthquake, and Earthquake Country Alliance advises having an inadequately braced chimney checked. Reducing its height or removing it can be simpler than bracing it.

For a stack that stays, the typical work is repointing open joints with a mortar matched to the brick, replacing spalled bricks, rebuilding a cracked crown with an overhang, and replacing a corroded cap. Near the ocean, stainless steel is the sensible metal for caps and ties.

For a factory-built chimney, repair is by parts. The code requires factory-built chimneys to be installed to the maker's instructions, so damaged sections, caps and supports are replaced with components listed for that system.

Scope first: a crown and cap is a smaller job than an extension or a partial rebuild. After that, height and access, especially on a narrow lot where equipment has to share space with a neighbor's construction, whether mortar and brick need matching, and whether the work is coordinated with a larger remodel.
