Chimney Repair for Foster City homes
Foster City is the one place in our area where almost nothing we do is traditional masonry. The whole city was built from the mid 1960s onward on engineered fill over former bay marshland, and the housing went up with prefabricated metal fireboxes and factory-built Class A chimneys enclosed in decorative wood-framed chases. These are manufactured appliances with a service life and specific replacement parts, not brick structures that can be repointed, and a technician who only knows masonry will misdiagnose them. The common Foster City findings are corroded chimney sections, deteriorated chase covers letting water into the framing, failed firebox panels and missing or damaged spark arrestors. Being surrounded by water on the lagoon system, humidity keeps the corrosion moving along faster than it would inland.
Built entirely from the mid 1960s on engineered fill, with prefabricated metal fireboxes and factory-built Class A chimneys in wood-framed chases rather than masonry. Typical failures are corroded chimney sections, leaking chase covers, cracked firebox refractory panels and missing spark arrestors. Lagoon humidity accelerates corrosion.

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
My Foster City fireplace is metal, not brick. Do you service those?
Yes, and they are the majority of what we see in Foster City. Factory-built systems are manufactured appliances, so they are inspected, serviced and repaired with the manufacturer's parts rather than repointed. It is a different job from masonry and it needs someone who knows the difference.
Water is getting into the chase around my chimney. What is that?
Almost certainly the chase cover, which is the metal lid on top of the framed enclosure. They are frequently built from galvanised steel that corrodes and ponds water, and once it lets go the water goes straight into the wood framing of the chase. It is one of the most common repairs we do in Foster City.
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.
