Chimney Repair for South San Francisco homes
The housing in South San Francisco splits neatly into two eras and the chimney work follows the split. The older neighborhoods below Sign Hill, laid out for workers at the steel plant and the shipyards, hold compact 1920s and 1930s homes with brick stacks that have now had a century of salt air on them. Westborough and the developments up the hill are a different proposition, built from the 1960s onward and far more likely to have a prefabricated metal firebox and a factory-built Class A chimney behind a decorative chase. Those two systems fail in completely different ways and are repaired with completely different parts, which is why the first question we ask on a South San Francisco call is which side of town the house is on.
A clear split between pre-war masonry near the older downtown and Sign Hill, and 1960s-onward hillside housing with prefabricated metal fireboxes and factory-built chimneys in decorative chases. Salt-laden air accelerates corrosion on metal systems and erodes mortar on the older brick.

Process
How the visit works
Diagnose the cause
Inspection first, including the roof and the flue, so the quote addresses the reason and not just the visible damage.
Scope and quote in writing
What we will do, the materials, the access needed and the price. Free, and yours to compare.
Protect the site
Roof and grounds protected before the work starts, and access arranged so nothing is dropped where it should not be.
Carry out the repair
Repointing, crown rebuilding, liner replacement, flashing, cap fitting or a full rebuild, depending on what the diagnosis found.
Water test and photograph
Where the repair addressed a leak we test it, and you get before and after photographs on completion.
Questions
FAQs
How do I know if I have a real masonry chimney or a metal one?
Look inside the firebox. Firebrick laid in courses with mortar joints means masonry. Smooth panels, often with a visible seam or a metal lip, mean a prefabricated unit. It matters, because a prefab firebox is a manufactured appliance with specific replacement parts rather than something that can simply be repointed.
Does the salt air really affect the chimney?
It does, particularly on the metal components. Caps, flashing, dampers and factory-built chimney sections corrode noticeably faster on this side of the Peninsula than they do inland, and a rusted-through cap is one of the more common findings here.
How do I know whether it needs repointing or rebuilding?
It depends on how deep the failure goes. If the mortar has eroded but the bricks are sound and the stack is straight, repointing is the answer. If bricks are spalling, the stack is leaning, or the structure has moved, rebuilding the affected section is the safer and often cheaper long-term option. The inspection tells us which.
My chimney leaks when it rains. Where is the water coming from?
Usually one of four places: a cracked crown, missing or failed flashing where the chimney meets the roof, porous or unpointed brickwork, or a missing cap letting rain straight down the flue. They present identically inside the house, which is why we diagnose before quoting.
