Sealing a sound crown or replacing a failed one
The written record after crown repair
When the job is done, you receive a written record of the work. It says what was removed, what was applied or formed, and how the flue joints were sealed. It also notes anything we saw that falls outside the crown.
Keep it with your home papers. If you sell the house, change contractors or call us about the chimney again, the record shows what was done at the top. It also makes a later assessment more specific, because nobody has to guess what material is up there.
Stone and metal tops on masonry chimneys
The residential code allows the top of a masonry chimney to be concrete, metal or stone. Concrete is the material people usually picture, but a stone slab or a metal top is sometimes used. Each needs slope, a drip edge and a sealed break at the flues.
If your chimney has a stone or metal top, we assess it against the same requirements. A stone slab may need its joints resealed or its bed repaired. A metal top may need fasteners or seams addressed. We explain what applies before any work is proposed.
The masonry a crown sits on
The residential code defines a masonry chimney as one built of solid units, hollow units grouted solid, stone or concrete. The crown sits on top of that structure and depends on it. A sound crown needs a sound chimney beneath it.
During the inspection we look at the masonry at the top as well as the crown. If the structure is sound, crown work can proceed as planned. If the masonry shows movement or loose units, we explain what needs attention first and price it separately.
Corrosion-resistant fittings on the crown
Anything metal fixed to the crown should resist corrosion. Brick industry guidance says a metal rain cap should be corrosion-resistant, and the same logic applies to fasteners set into the concrete. Rust spreading from a fixing shows where water sits.
When a cap is reset on a new crown, we look at the condition of its fasteners. Rusted fixings are replaced with suitable ones rather than screwed back into fresh concrete. If the cap itself is corroded, replacing it is discussed as a separate item.

Crown repair answers for Mission Bay
Why does a new crown need to overhang the brick?
An overhang with a drip edge throws water clear of the brick face instead of letting it run down the chimney. The code also calls for a drip edge on the top of a masonry chimney. Without one, water can keep soaking the top courses.
How does the inspection discount apply to crown repair?
Approve crown work in the 72 hours after your free inspection and a 10% discount applies to it. The window runs from your own inspection, and it covers any service on the estimate you book in that time.
Can crown repair stop the stain on my ceiling?
It can, if the crown is the confirmed entry point. Stains near a chimney can also come from flashing, the cap or the brick face. We explain which parts we checked, and we add a hose water test only if this job calls for one.
