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 Masonry Repair 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)
Two different kinds of crack
Weather damage looks like surface scaling and spalled faces, spread across the exposed elevations of a stack. Without much freeze-thaw, California sees far less of it than the northeast does.
Movement damage looks different. It is a single crack running diagonally in steps, following the mortar joints, or a clean separation where the chimney meets the wall. That is the structure telling you it has shifted, and on a pre-war unreinforced stack in seismic country it is the finding that matters.
Why the distinction decides the job
Weather cracking is repointed and that is the end of it. Movement cracking is repointed only after the movement has been understood, and frequently the correct work is a seismic retrofit rather than a masonry repair.
Stucco hides everything
A great many California chimneys are stucco over brick or block, which means the masonry condition is unknown until the render cracks or sounds hollow. Tapping it and putting a camera in the flue tells you more than looking at the outside.
Repointing and rebuilding
Repointing rakes out failed mortar to a sound depth and replaces it, and it works while the brick is still good. Rebuilding takes the stack down to a sound course and lays it again, which is what is needed once faces have gone or the stack has moved.
Rebuild in reinforced masonry
Where a California stack is rebuilt, it should go back with reinforcement and a proper tie into the framing rather than as another unreinforced stack. Rebuilding it the way it was is a missed opportunity and, in seismic country, a poor one.
Access and cost
Tile roofs complicate access considerably — tiles break underfoot and have to be lifted and relaid. Ask for access to be itemized so quotes compare honestly.

Chimney Masonry Repair 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 long should repointing last?
Twenty to thirty years with matched mortar on a stable structure.
Should we rebuild or remove?
If nothing vents into the chimney any more, removing above the roofline is legitimate and often cheaper. If something does, rebuilding in reinforced masonry is the route.
