Chimney Rebuild for Sausalito Homes

Chimney rebuild in brief

A chimney rebuild takes down the damaged part of a masonry chimney, often everything above the roofline and sometimes more. It then lays the chimney back up course by course with new brick and mortar. The job usually includes a new crown, new flashing where the stack meets the roof, and a cap or spark arrester on top. It fits when a chimney leans, has lost the mortar that holds it together, or has failed beyond what spot repairs can fix. The steps from tear-down to finished crown are in how chimney rebuild works.

What Sausalito's rules mean for a masonry chimney rebuild

Two sets of City of Sausalito requirements bear directly on rebuilding a chimney. One comes from the Building Division's Local Building Ordinances. The other comes from the city's Historic Design Guidelines (September 2011). Both affect the plan before any brick comes down.

Required clearance above nearby roofs

The City of Sausalito Building Division asks that plans specify chimney spark arresters and dimension the arrester's lowest opening at least two feet above any roof within ten feet horizontally (source: City of Sausalito Building Division, Local Building Ordinances). For a rebuild, that clearance shapes the design. The finished height of the stack has to leave the arrester's lowest opening at that distance above every roof surface within ten feet, including dormers, upper roofs and other sections of your own roof. That means measuring before tear-down, not after the crown is poured. It also means the arrester is part of the plan from the start, with its height shown on the drawings.

Historic properties: repair comes before rebuild

The City of Sausalito's Historic Design Guidelines (2011), guideline 2.71, direct that decorative roof elements, including chimneys, be preserved on historic properties. Guideline 2.51 lists chimneys among significant concrete features to preserve and advises against rebuilding a major portion that could be repaired (source: City of Sausalito, Historic Design Guidelines, September 2011).

If your home is a historic property, the first question is whether the chimney can be repaired instead of rebuilt. Repointing, crown work or rebuilding only the failed section may keep more of the original. Where a larger rebuild can't be avoided, matching the original brick, mortar color, profile and any decorative detail matters more than usual. We document the damage at the estimate so you can see why a repair will or won't hold.

When a rebuild fits, and when a smaller job is better

A rebuild is the right call when the structure itself has failed. Smaller problems, like a cracked crown, a few eroded mortar joints or a leak at the flashing, usually call for targeted masonry or crown repair that keeps more of the original chimney. That matters even more on a historic property. For a side-by-side look at both options, read our guide to chimney repair vs rebuild.

• A leaning chimney that has pulled away from the house or roofline usually needs rebuilding from the point where it shifted.
• Brick that is loose, spalled or missing across a large area, not just a few units, points toward a rebuild.
• Mortar that has washed out deep into the joints over much of the stack can mean the masonry no longer holds together.
• Isolated cracks, a damaged crown or one bad course of brick are usually repair jobs.
