What does it take to fix an old brick chimney in Oakland?
Chimney repair in Oakland means fixing the brick, mortar and firebrick of your chimney so it keeps water out and holds together. On an old chimney built without steel inside, it also means deciding whether to repair it, brace it, shorten it or take it down. At Anchorstone Oakland Concrete and Masonry, I go through those choices with you before we touch a brick.
Most calls start with something you can see, like mortar sanding out of the joints, bricks loose at the top, a crack that showed up after a shake or a stain on the ceiling by the fireplace. The price turns on how far the damage goes, how tall the chimney is, how hard it is to reach on your roof and which way you decide to go, because bracing or removing a chimney is a bigger job than fixing its joints. The schedule turns on dry days for roof work, any design work bracing needs and the city's permit when the job needs one. My written estimate gives you your own figure and my honest take on what can wait.
How we handle chimney repair
I start on the roof and inside the house, checking the top courses of brick, the crown, which is the concrete cap on top, the mortar joints, the firebox where the fire sits, and the chimney where it passes through the attic, because the damage you see usually starts somewhere else, most often with water. With an old brick chimney, I lay out every option with you, from repairs to taking it down, before anything gets fixed. If you're repairing it, we cut out failed mortar and pack the joints fresh, reset or replace loose brick, rebuild the top where it's come apart and replace cracked firebrick. If you want to keep the chimney standing for the long run, I tell you up front that bracing it properly takes a design made for that chimney, so you can plan for it before we start.
Chimney trouble usually doesn't stop at the chimney. If the mortar is worn on the walls around it too, tuckpointing refills those joints before water gets behind them, and cracked or flaking bricks elsewhere on the house are brick repair work we can do on the same visit.
Repair it and keep it
This suits a chimney that's mostly sound, with worn joints, a few loose bricks up top or a cracked crown. It's the smallest job, but it doesn't change how an old unreinforced chimney behaves in a strong quake.
Brace it in place
This suits owners who use the fireplace and want the chimney to stay. It's the most involved way to keep one, because the bracing has to be worked out for how your chimney was actually built.
Lower it near the roofline
This suits a chimney you no longer use but don't want to fully remove. Taking it down to just above the roof leaves far less brick up high where it can fall.
Replace it or remove it
This suits owners who'd rather be done with the risk for good. We take the brick out and either put in a lighter metal flue or close up the wall and roof where the chimney stood.
If bricks have come loose at the top or the chimney shifted in a quake, keep people clear of it and call (510) 216-0213 right away.

(510) 216-0213Chimney repair in Oakland: permits, licensing and woodsmoke rules
Whether your chimney job needs a permit depends on the work, and the city's Bureau of Building is the office to ask, since it oversees construction in Oakland. The city requires anyone applying for a building permit to first turn in an approved recycling plan and recycling summary report, and when your job needs a permit, we handle that along with the application and the inspections. The state licensing board's C-29 masonry class covers chimney work and refractory work, which is the firebrick that lines a firebox. We're licensed and fully insured, and it's fair to ask any contractor which license they hold. If you burn wood, check the Bay Area Air District's current woodsmoke rules before any fireplace work, because they've been amended.
We're based in Oakland and work across the East Bay, and most of the chimneys we see sit on older houses, laid without steel and worn at the joints by years of rain. We find the same kind on jobs in Berkeley and Piedmont, so whichever way you go, I start by checking how yours was built.
Chimney repair questions we hear in Oakland
How much does chimney repair cost in Oakland?
Chimney repair in Oakland usually runs about $750 to $10,500 per project, from simple cleaning tasks at the low end up to structural repairs or a full replacement at the top. Where yours lands depends on how much brick is failing and whether you repair, brace or remove the chimney, and the written estimate gives you your own figure. Your satisfaction, guaranteed.
Can my brick chimney fall in an earthquake?
Yes, an unreinforced brick chimney, one built without steel inside, can come down in a strong earthquake. FEMA warns these chimneys can fall outward onto people walking by or into the house onto the people inside. A retrofit makes it more likely you can stay in your home right after a quake.
What is the most reliable fix for an unreinforced brick chimney?
The same federal guidance says the most reliable fix is to replace the brick chimney with a metal flue inside a framed enclosure, or to remove the chimney and firebox altogether. Both take the brick out, so it's worth weighing removal before paying for smaller repairs. For a chimney you don't use, the guidance says lowering it to no more than 1 to 2 feet above the roofline limits the damage it can do, and that's usually where I'd point you.
When should I get a chimney inspection in Oakland?
The chimney trade association recommends a Level 2 inspection, the more thorough kind, before relining the flue, when you sell, and after a fire, storm or earthquake likely to have caused damage. In Oakland, that means booking one after any real shake. The inspector goes up on the roof and checks the chimney through any attic, basement or crawl space they can reach, so clear a path to those before the visit.
How do I know if my chimney needs repair?
Look for mortar crumbling out of the joints, loose or flaking brick near the top, a cracked crown or water stains around the fireplace or ceiling. A chimney that leans or pulls away from the house needs a call right away, while a few worn joints can usually wait for dry weather.
What causes a brick chimney to crumble?
Water is usually the cause, soaking into worn mortar and the top bricks and breaking them down as they wet and dry year after year. A cracked crown lets it in fastest, which is why I fix that before patching the joints below it, or the same damage comes back.
Other brick work that often goes with a chimney
Worn mortar joints let water into a wall long before bricks come loose, and refilling them with matching mortar keeps the rest of the masonry sound.
Cracked, chipped or flaking bricks on walls, steps or the house itself can be cut out and replaced so water stops working its way in.
