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.

Spark Arrestor Installation in San Mateo
Much of San Mateo's housing was built before central cooling was normal and often before ductwork was, so heating and cooling arrived separately and at different times. That is why so many houses here run a boiler for heat and something entirely different for cooling.
About 58% of homes in San Mateo predate 1970, so the original heating system has usually been replaced at least once and cooling added afterward; 37% 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)
What it is for and where it is required
An arrestor is mesh over the flue opening that stops burning fragments leaving the chimney. In fire country that is not a theoretical concern, and California requires it across State Responsibility Areas with the mesh opening specified rather than left to preference. Many local fire codes require one regardless of SRA status.
It is usually combined with the cap, so one component does both jobs — rain out, embers in.
Mesh that blocks is its own hazard
Arrestor mesh loads with soot over time, particularly on a wood- burning appliance. A blocked arrestor stops the flue drawing, which pushes smoke into the room and makes the appliance burn badly. That is why the annual look matters as much as the original fitting.
Corrosion near the coast
Galvanized mesh does not survive marine air. From San Diego up through the Bay Area, stainless mesh and stainless fixings are the only sensible specification.
Checking what you have
A great many older California chimneys have no arrestor at all, or have one that corroded through years ago, or have one blocked solid. None of that is visible from the ground.
What to ask for
Confirmation that the mesh meets the required aperture, that it is stainless, and that it is fixed so it cannot lift in wind. Photographs of the fitted part are reasonable to expect.
Do it with the annual inspection
The arrestor is at the top of the chimney, which is where the inspection goes anyway. Checking and clearing it costs almost nothing as part of that visit and a great deal as a separate one.

Spark Arrestor Installation in San Mateo — FAQs
Nothing vents into our chimney any more. Does it still matter?
Less urgently, but yes. An uncapped disused flue collects rain, leaves and nesting for years with nobody noticing, and water sitting inside it damages the structure from within. If the chimney is genuinely finished with, removing it above the roofline and roofing over is a legitimate option. If anything at all still vents into it — a water heater in particular — then it matters as much as it ever did.
What chimney problem is most common around San Mateo?
Unreinforced Victorian and Craftsman stacks on active fault country. That pattern is regional rather than universal — san Francisco, Oakland, Berkeley, San Jose and the Peninsula. It is worth knowing before you book, because it tells you what someone should be looking hardest at here.
How much does chimney work cost in San Mateo?
It depends entirely on what the chimney turns out to need, and the spread is wide. Sweeping, an inspection, a cap or a damper repair are the inexpensive end and are usually done in one visit. Relining, rebuilding above the roofline and full crown recasting are the expensive end. Nobody can quote it honestly over the phone, which is why the inspection comes first. The contractor you are introduced to sets their own prices and agrees them with you directly.
Do you cover all of San Mateo?
Yes — all 5 ZIP codes in San Mateo and the surrounding towns. Tell us where you are and we put you in touch with a company that covers it.
How quickly can someone get to me in San Mateo?
For a routine inspection or sweep, usually within a few days, and sooner outside the fall rush. Late spring through early fall is the quiet season and the easiest time to book. If you have had a chimney fire, or you can smell gas or have a carbon monoxide alarm sounding, that is not a scheduling question — leave the building and call emergency services from outside.
My fireplace smokes into the room. What is wrong?
Several possible causes, and they need different work. A blocked cap or arrestor, a damper not opening fully, a smoke chamber that was never parged, a flue too small for the fireplace opening, or a chimney too short relative to the roof around it. A house sealed tight enough to run under negative pressure will also pull air down the flue. An inspection separates them; guessing does not.
How often should it be checked?
Annually, with the inspection. On a regularly used wood appliance, expect it to need clearing.
Can I fit one myself?
The part is available. Working at the top of a chimney is the risk, and getting the aperture and the fixing right matters if it is a code requirement.
