Leave the building and call from outside — that is an emergency services call, not a service call. A blocked or failed flue is one of the ways carbon monoxide reaches a living space, and headaches that clear when you leave the house point the same way. If you have had a chimney fire — a roaring sound, dense smoke, or debris on the roof — do not light another fire until the flue has been inspected.

Chimney Cap Installation in San Francisco
The systems we see in San Francisco tend to share a history — a heating system replaced once or twice, cooling added later, and ductwork extended as rooms were added rather than designed for the house as it now stands. Most comfort complaints here start there.
About 46% of homes in San Francisco were built before 1940 — old enough to have been built with radiators and no ductwork at all; 33% of them heat with electricity, so a fireplace here is used by choice rather than by necessity and tends to be inspected far less often. (US Census ACS 2022)
One component, two jobs
A cap keeps rain out of the flue and stops birds and squirrels nesting in it. The mesh sides stop embers leaving. In California those are not separate purchases — a cap with correctly specified mesh satisfies both, and in a State Responsibility Area the mesh is a requirement rather than an option.
Mesh aperture is specified
The opening size is set, not left to preference. A cap without mesh is not an arrestor, and mesh that is too fine loads with soot and chokes the draft — which is why it needs looking at annually rather than fitting and forgetting.
Marine air eats galvanized
From San Diego up through the Bay Area, galvanized caps corrode within a few years and streak rust down stucco. Stainless cap, stainless mesh and stainless fixings — a stainless cap on plated screws fails at the screws.
Fitting on a tile roof
Access is the cost driver on much of California housing. Terracotta barrel tile breaks underfoot, so reaching a chimney means lifting tiles and working off battens, and a contractor who simply walks the roof will leave you with broken tiles as well as a new cap.
Do it with the crown
Same access, same visit. Fitting a cap while crown work is happening costs far less than a second trip.
Fixing method in wind
A cap that clamps to the flue tile or anchors into the crown stays put. One relying on friction does not, and in a Santa Ana wind that gets tested.

Chimney Cap Installation in San Francisco — FAQs
Should the chimney be repaired or rebuilt?
It depends how far the damage goes. If a key scrapes mortar out but the brick is intact, that is repointing. Once brick faces have flaked through, a brick can be rocked by hand, or the stack leans, repointing has nothing sound to bond to and a rebuild is the honest answer. Most rebuilds stop at the roofline, because that is the section taking weather from every side.
Do you charge for a quote in San Francisco?
We charge nothing at any point — contractors pay us, you never do. What a company charges to attend or to carry out an inspection is theirs to set, so agree it with them before they come out. An inspection is a real piece of work with a written report attached, and it is reasonable for it to be chargeable.
How often should a chimney be inspected?
Annually, whatever it vents — that is the NFPA 211 standard and it covers gas and oil appliances as well as wood. Sweeping frequency is separate and depends on what and how much you burn. An appliance used twice a year still needs the annual look, and those are the ones where neglected faults turn up.
Do we need a chimney liner?
If a camera survey finds cracked tile, washed-out joints or a separated liner, yes. You also need one whenever the flue is the wrong size for the appliance now venting into it, which is the common case after any change of fuel or appliance. A liner is sized from the appliance manufacturer venting tables, not from what happens to fit down the chimney.
What does a Level 2 inspection include?
Everything in a Level 1 visual check, plus a camera survey of the entire flue and an examination of accessible attic, crawl space and basement areas. It is required on a property transfer, on any change of fuel or appliance, and after a chimney fire. A general home inspection does not include it.
Is chimney waterproofing worth doing?
On sound, porous, exposed masonry it genuinely slows the water absorption that destroys brick. On masonry that has already started to flake it is worse than doing nothing, because it traps water behind the damaged face. And it has to be a breathable repellent rather than a film-forming sealant — the film is what causes the damage people then blame on waterproofing.
How long does stainless last on the coast?
Decades. Galvanized in marine air may not manage five years.
Something is nesting in the chimney.
It has to be empty before capping. Some birds have legal protection in nesting season, so the order is remove, then cap.
