Chimney repair with a free inspection in LaVina

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 LaVina says which part of the crown has failed and whether it can be repaired or has to be replaced.

Spark arrestor screens and their size

Some chimney caps carry a mesh screen around their sides. That screen is a spark arrestor, and on a masonry chimney the Florida Building Code lists what it has to meet.

A spark screen only helps while its mesh is open. Soot, creosote or leaves packed into it cut down the opening the smoke has to pass through, which works against the open area the code sets.

Where a screen is clogged, bent or rusted through, our crew checks whether cleaning will do or the cap needs replacing, and whether a replacement is sized for your flue. Screen and cap then share one priced line.

• Its open area is at least four times the open area of the flue outlet
• The screen resists heat and corrosion
• It can be reached and removed so the flue can be cleaned

A framed chase around a metal chimney

A chase is a wood-framed box built around a factory-built chimney pipe, finished with siding or stucco to look like part of the house. The pipe carries the smoke. The chase only covers and hides it, so its walls are built like any other exterior wall.

That means the Florida Building Code rules for exterior walls apply. A water-resistive barrier goes over the sheathing, continuous behind the siding and lapped upper layer over lower, and flashing keeps water out of the wall cavity and away from the framing. When a chase leaks, the top and the roof line are the first places to look.

Water inside a chase can stain the ceiling beside the fireplace or soften framing long before the siding looks wrong. Our chimney chase repair service opens only what needs opening, replaces wet sheathing and barrier, and closes the wall with matching siding. Each layer carries its own price.

Decorative shrouds on a factory-built chimney top

A shroud is a decorative metal housing set over the top of a chimney to hide the cap and pipe. On a factory-built chimney, the Florida Building Code allows one only where it is listed and labeled for that specific chimney system and installed per the maker's instructions.

The top of a factory-built chimney is part of what was tested. A shroud that encloses the cap can change conditions at the outlet, and the code ties it to the system's own listing. A catalog shroud can look right and still sit outside it.

If a shroud is already in place, the details below show whether it was made for your system. A listed one is repaired or replaced with the listed part. An unlisted one comes off, and the estimate shows the cap or listed shroud that replaces it.

• The maker and model on the chimney label
• A matching listing for the shroud itself
• An install that follows the shroud maker's instructions
