Crown repair choices for homes in Dolphin Isles
Moss and organic growth on the crown
A crown that stays damp can support moss or other growth. The growth holds moisture against the concrete and keeps the surface wet longer after rain. It also hides cracks that would otherwise be easy to see.
Before any crown repair, the surface is cleaned so the concrete can be assessed. If growth has returned after earlier cleaning, that tells us water lingers on the top. We look at slope and drainage as the cause, rather than treating the growth as the only problem.
Appliances that vent into the chimney during crown work
A chimney may serve more than the fireplace. A furnace or water heater can vent into one of its flues. Crown work must not block a flue that an appliance depends on, even for a short time.
Tell us about every appliance connected to the chimney before the visit. We plan the work so that flue stays open, and we explain whether the appliance should be turned off during any part of the job. Its own servicing is not part of crown repair.
When crown sealing is the wrong recommendation
Sealing is a smaller job than replacement, so it is tempting to hear that a crown only needs a coat. On the wrong crown, that answer buys a short delay and another repair later. The coating will not hold loose concrete in place.
We recommend sealing only when the crown meets the conditions the product requires. When it does not, we say so plainly and explain what replacement involves. You make the decision, but you make it with an accurate picture of the top of your chimney.
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.
Crown work we price line by line
- Firmness of the existing concrete
- Cap removal and reinstallation
- Top course brick condition below the crown
- Separate lines for cap or liner defects
Chimney crown questions we hear
Will a new cap stop water coming through the crown?
No. A cap covers the flue opening, while the crown covers the masonry around it. Water that enters through a broken crown keeps entering under a new cap. We check both parts and price each one on its own line.
Can you repair the crown on a stone or stucco chimney?
The code allows a concrete, metal or stone top on a masonry chimney, and a stucco or stone face does not change the crown's job. We assess the top the same way and treat repairs to the sides as separate work.
What should I tell you when I call about the crown?
Mention what you have seen, such as concrete pieces on the roof, a stain inside or cracks visible from the yard. Tell us about earlier patches or coatings and any appliance that vents through the chimney.
