You probably found this page because you looked up at your chimney and saw something wrong at the top, or because a home inspector flagged crown damage before a sale. Maybe you noticed pieces of mortar on the roof after a storm, or dark staining running down the brick. That’s how crown failure usually announces itself: quietly at first, then all at once with water where it doesn’t belong. The crown is the concrete or mortar cap sitting on top of the chimney stack, the first line of defense between San Francisco’s fog and rain and the inside of your flue. When it cracks, water gets in and starts working on everything below it.

Which Famco Models This Applies To

Famco manufactures chimney caps and related crown components, and most of what we see in San Francisco falls into two groups: the standard galvanized or stainless mesh-top caps sized for common flue diameters, and the custom-cut crown caps used on older masonry chimneys where the flue tile dimensions don’t match modern sizing. The compatibility gotcha we run into constantly: a Famco cap’s base plate diameter must match your flue tile’s outside measurement, not the inside opening, and older San Francisco homes frequently have flue tiles that are slightly out of round. Over 60 years of damp salt air and seismic settling, a clay tile that started circular is now a little egg-shaped, and a cap sized by guesswork won’t seat right.

The best way to identify exactly what you need is to check the label on the underside of your existing cap, which typically carries the Famco model number and diameter. No label? Measure the flue tile’s outside width across its widest point, in inches, and bring that with you when you call. For genuine Famco replacements, we order direct from factory distribution. For common sizes where Famco’s lead time runs long, we also carry quality aftermarket equivalents that match spec, which is often the faster fix with no functional downside.

Signs Your Famco Crown Repair Is Failing

• Visible cracks running across the crown surface. This is the most direct sign. San Francisco’s freeze-thaw cycles are mild compared to the Sierra, but years of fog, rain, and the occasional cold snap still work cracks wider over time. A hairline crack becomes a water channel.
• Spalling, or flaking, of the crown material. If you’re finding small concrete or mortar chips on the roof or in the gutter near the chimney, the crown is shedding. This means water has already penetrated the surface and is breaking the material apart from within.
• Efflorescence, which is white staining on the brick below the crown. That white powder is salt left behind when water evaporates out of the masonry. It’s a reliable marker that water is moving through the crown and into the chimney structure.
• Rust staining around the base of a Famco cap. If the metal cap’s anchoring bolts or the cap base itself show rust bloom, water is pooling around the crown’s edge instead of draining away. Pooling water means the crown’s slope or overhang has failed.
• Water in the firebox after heavy rain. This is the symptom that gets people on the phone fastest. Water showing up inside means the crown, the cap, the flashing, or all three have opened a path from roof to hearth.

Replacement Cost & What’s Included

In San Francisco, a Famco crown repair or replacement with a new cap typically lands between $375 and $750 installed. The range comes down to a few things: how much of the old crown is sound enough to build on, whether we’re repairing with a resurfacing compound or pouring a new crown from scratch, chimney height and roof access, and which cap configuration your flue requires.

Every repair starts with a written price delivered before work begins, with parts and labor separated so you can see exactly what you’re paying for. That price covers removal of the failing material, crown preparation, application of the new crown, and installation or reinstallation of the Famco cap. If there’s flue damage below the crown, that’s scoped and priced separately, and you’ll see the camera footage yourself before we recommend it. There are never surprise charges at the end of the job.

The work is covered by our 365-Day Done Right Promise. If the repair fails within a year, we come back and fix it at no cost. The written guarantee is included on every repair we do, not sold as an add-on.

DIY or Call Us?

Here’s an honest split. What an owner can safely do is look: check for visible cracks from the ground or an upper window, note whether the cap is still sitting square, and keep an eye out for water in the firebox after rain. Tell me what you’re seeing, and I’ll tell you straight what it means.

What shouldn’t be done as a DIY project is the crown work itself. A proper crown repair requires removing and re-pouring material on a sloped surface, typically from a ladder or roof staging, while matching the crown’s overhang and drip edge. It’s cumbersome, and it’s dangerous when it goes wrong: losing footing means a fall, and a poorly mixed crown with the wrong slope will fail again inside two years. We’ve repaired more than a few DIY crowns in neighborhoods like the Richmond and Noe Valley where the homeowner saved a few hundred dollars the first time and paid double the second. If your crown is cracked, call us at (831) 534-3789 and we’ll give you a straight answer and a written price.
