Masonry and factory-built chimney repair in South Apopka

The crown is the roof of a masonry chimney

The top of a masonry chimney is its roof. Homeowners call it the crown, and the Florida Building Code calls it the chimney cap. The code wants it made of concrete, metal or stone, pitched so water runs off, with a drip edge and a caulked bond break at every flue liner.

Every part of that list does a job. The slope sends rain off the top instead of letting it sit. The drip edge lets water fall clear of the brick faces below. The bond break keeps the liner and the cap from being locked into one rigid piece.

Wear tends to show at the surface and the edges first, as cracks, crumbling corners or low spots where water now stands. Our chimney crown repair service handles the fix, and the estimate for homes in South Apopka says which part of the crown has failed and whether it can be repaired or has to be replaced.

Cracks in a stucco chimney finish

A crack in stucco is a break in the outer skin, and the real question is what sits behind it. On a framed chimney, the Florida Building Code puts a water-resistive barrier behind the plaster. Over wood-based sheathing that barrier is normally two separate layers, with flashing directed between them so water that gets in has a way to drain.

Caulking a crack from outside can look tidy for a season. If water has already reached the barrier or the sheathing, the bead just seals it in. Brown streaks below the crack, spots that give when pressed and paint that bubbles can mean the damage runs deeper than the finish.

That is the decision our stucco chimney repair service makes first. When the layers behind are sound, the crack is cut out and patched in coats that match the wall. When they are not, the section is opened, the barrier and flashing are rebuilt and the plaster goes back on. The estimate states which case applies.

The metal top of a framed chase

The top of a chase is sheet metal, and on a factory-built chimney it is part of the system. One maker's instructions, DuraVent's for its DuraChimney II chimney, set the chase top flashing on spacers above the framing, leave a ventilation opening around the pipe, seal a collar to the pipe just above the flashing and place the chimney cap above that.

A flat or sagging top holds water, and rust starts where water sits, then runs down the siding as streaks. A top sealed tight to the pipe or pushed down onto the framing can also close off the ventilation space those instructions call for.

Replacing it means matching the chimney system underneath, not only the size of the box. Our chase cover replacement service checks the points below before a new top is specified, and the estimate lists the top, the collar and any framing repair as separate items.

• The chase size and the pipe diameter
• The collar and its seal to the pipe
• Rot or rust in the framing under the old top
• Clear ventilation space around the pipe

Same-day visits when the schedule allows

Same-day service is available when the schedule allows. A sudden leak around the chimney, a damper stuck open or a piece of masonry that has come loose are the problems where an early look helps most, because each one can get worse while it waits.

The first visit is for finding the cause and writing the estimate. No repair work goes ahead until you have approved that estimate, even when the fix turns out to be small, and homeowners in South Apopka see what the repair involves before anything starts.

When you get in touch, a clear description helps us plan the visit. These details cover most of it.

• What you see, where it is and when it started
• Whether it shows up only when it rains
• Whether the fireplace has been used since
• Roof access, gates and pets
