Chimney Sweep 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
Set up and seal
Drop cloths over the hearth and floor, and the fireplace opening sealed so nothing escapes into the room.
Sweep the full run
Rotary and hand brushes from the firebox through the smoke chamber, throat and flue to the cap, sized to your flue.
Vacuum under negative pressure
A HEPA vacuum runs the whole time so the soot goes into the machine rather than onto your furniture.
Inspect what the brush exposed
Camera and visual check of the liner, damper, smoke shelf and crown now that the surfaces are clean.
Report and photograph
We show you what we found, photograph anything that needs attention, and give you the written estimate before any repair work.
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 often should the chimney be swept?
Once a year for anything you burn regularly, and the industry standard is an annual inspection regardless of use. If you burn most evenings through the winter, or you burn wood that was not fully seasoned, it is worth doing before every heating season.
How long does a sweep take?
A straightforward single fireplace usually runs about an hour to ninety minutes. Heavy glazed creosote, a blocked flue or a second fireplace adds time, and we will tell you before we start rather than after.
