Chimney Masonry Repair for Larkspur Homes

Masonry repair on a home in Larkspur's historic Resources Inventory

The City of Larkspur states that any project, including repairs, affecting the exterior of a structure listed in Larkspur's Historic Resources Inventory may be subject to design review to protect its historic character (source: City of Larkspur, Historic Structures Standards To Be Applied For Design Review). A chimney is part of a home's exterior, so replacing brick, repointing joints or repairing a crown on a listed structure can fall under that review.

Who this applies to

The rule covers owners of structures listed in the Historic Resources Inventory. If your home isn't on that list, design review under these standards doesn't describe your project. If you aren't sure, ask the City of Larkspur before scheduling the repair. The Inventory is the City's list, and the City decides whether review applies.

What it changes about the repair

The same City of Larkspur design-review standards for historic structures bar chemical or physical treatments, such as sandblasting, that damage historic materials, and call for the gentlest cleaning means possible. For masonry repair, this matters most during prep. Soot, staining and old mortar residue on a listed chimney get cleaned with the gentlest method that does the job, and they are not blasted off. If your home is listed, tell us when you request the estimate so the scope is planned around that requirement.

Chimney masonry repair in brief

Masonry repair covers the brick, mortar and crown of a masonry chimney. That means replacing cracked or spalling brick, tuckpointing crumbling mortar joints, repairing a cracked or deteriorating crown, and rebuilding sections too damaged to patch. The aim is to stop water from getting into the masonry, because water drives most chimney deterioration. The chimney masonry repair service explains the steps, the materials and what to expect on the day in more detail.

Is it masonry repair, or a different job?

• Cracked, flaking or spalling brick, or mortar you can scrape out with a key: this is masonry repair.
• A crown that is cracked or crumbling at the top of the stack: this is masonry repair, focused on the crown.
• Damage running through much of the stack, or a chimney that leans: this may need a partial or full rebuild. Our guide to chimney repair vs rebuild explains how that decision is made.
• Water coming inside while the brick looks sound: the source may be the flashing where the chimney meets the roof. That calls for leak or flashing repair, not brickwork.
• An open flue top that lets in rain, debris or animals: a cap is the fix. Details are under chimney cap installation in Larkspur.
