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.

Seismic Chimney Retrofit in San Luis Obispo
The systems we see in San Luis Obispo 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.
64% of homes in San Luis Obispo heat with natural gas, so oversized flues left behind by an earlier fuel are the recurring finding here. (US Census ACS 2022)
What unreinforced means and why it matters
Masonry built before modern code is brick laid in mortar and nothing else. There is no reinforcing steel running through it and typically no mechanical tie between the chimney and the structure it leans against. In a lateral event the chimney and the house move independently, and the chimney is the part with no tensile strength.
The failure mode is not subtle. Stacks shear at the roofline and fall, and they fall through the roof or onto whatever is beside the house.
What the retrofit involves
Galvanized steel strapping and anchor plates connecting the chimney to the roof and floor framing, usually reached through the attic. On a typical single-family house it is a day of work rather than a rebuild, and it does not change what the chimney looks like from outside.
When bracing is not the answer
Where the stack is already badly cracked or has moved, strapping a compromised structure to the building is not a fix. The honest options then are rebuilding in reinforced masonry, or removing the chimney above the roofline and venting differently — which, if nothing vents into it any more, is frequently the most sensible outcome.
Permits and who does the work
Seismic retrofit is structural work. Many California cities and counties require a permit and an inspection, and some have specific prescriptive standards for chimney bracing.
Ask who pulls the permit
It should be the contractor, and the CSLB license classification should cover structural work. Check the license on the board's free lookup before anything starts.
Insurance and disclosure
An unbraced unreinforced stack is a known hazard and it comes up on sale. Having the retrofit done and documented is worth more than the cost of it when the property changes hands.

Seismic Chimney Retrofit in San Luis Obispo — 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 Luis Obispo?
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 a retrofit take?
A day on a typical house. Access through the attic is what determines how straightforward it is.
Will it change how the chimney looks?
No. The work is inside the roof structure, not on the visible masonry.
