Spark Arrestor Installation in California
In State Responsibility Areas a spark arrestor over the flue is a legal requirement with a specified mesh aperture. It is also the least expensive part on the chimney, which makes it strange how often it is missing.
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.

What these repairs look like
Illustrative examples of the work described here. More in our disclaimer.
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 — frequently asked questions
Is an arrestor legally required?
In State Responsibility Areas, yes, with a specified mesh aperture. Many local codes require one anywhere. Check with your local fire authority if you are unsure.
Is the arrestor the same as the cap?
Usually the same component — a cap with mesh sides does both jobs. A cap without mesh is not an arrestor.
Will the mesh restrict the draft?
Correctly specified mesh does not. Mesh too fine, or mesh that has loaded with soot, does — which is the more common problem.
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.
