Choosing and fitting chimney caps in Seven Isles
Spark arrestor mesh and its opening size
Where a spark arrestor screen is fitted to a masonry chimney, the Florida Building Code limits the size of its openings in both directions. The mesh must be fine enough to stop embers and open enough not to choke the flue with soot.
That is why screen choice is not only about keeping animals out. A mesh that is too fine can clog and hold smoke back, while one that is too open can let larger embers through. We choose a screen that meets the code and suits how you use the fireplace. The estimate states the screen type so you can see what was chosen.
A cap that comes off for cleaning
The Florida Building Code requires a spark arrestor to be placed with access for cleaning. Its screen or the cap itself must be removable so the flue can be cleaned. A cap sealed permanently to the tile makes later sweeping harder and can hide a clogged screen.
We fit caps so they can come off the way the maker intends, with bolts, screws or a removable lid. At handover, we show you how it opens, even if you do not plan to do it yourself. Anyone sweeping the chimney in Seven Isles later will be able to reach the flue without breaking anything.
Flashing leaks are not cap problems
Flashing is the metal that seals the joint where the chimney passes through the roof. Water that enters there runs down the outside of the flue and shows up on ceilings, walls or in the fireplace. It can look like a cap problem from indoors.
We check the flashing when water is part of the complaint. If it is the source, we tell you, and flashing repair is quoted as its own job. A new cap would not change that leak. Knowing where the water really comes in saves you paying for a cap that was not the cause.
Galvanized caps in air that carries salt
Galvanized coatings wear faster where the air carries chlorides from nearby salt water. Corrosion data for zinc coatings rank warm marine air close to industrial air in how hard it is on the metal. Wind direction and distance from the shore change the rate.
For a home close to the coast, that shifts the metal choice for a cap. A galvanized cap may still be an option, but we explain what to expect from it in that exposure. The estimate names the metal we recommend for the flue and the reason, so you can weigh cost against how the cap will weather.

Settling chimney cap questions in Seven Isles
Why does smoke come into the room after a cap was fitted?
A clogged screen, a lid set too low or a cap that is too small for the flue can hold smoke back. Stop using the fireplace and ask us to look at the cap and the flue before the next fire.
How does the inspection discount apply to cap replacement?
Your own free inspection starts the window. For the next 72 hours, the cap and any other item on that estimate can be approved at 10% off, and later approvals keep the written price.
What happens if the flue tile is cracked under the cap?
A cap clamped to a cracked tile may not hold, and the crack can let water into the chimney. We list the damaged tile as its own line on the estimate so you can decide on that repair before the cap goes on.
