From flue measurement to fastened cap in Fisher Island
Band caps that clamp around the top brick
Another style wraps a metal band around the top course of brick and tightens at the corners. It is held by tension alone, so nothing is drilled into the crown or the tile. That can suit a chimney where the crown is thin or the flue tiles sit flush with the top.
The catch is the brick itself. A band cap needs a top course that is square, sound and firmly mortared. Loose or spalled brick at the top gives the band nothing reliable to grip. We check that course before recommending this style, and any masonry repair is priced as its own line.
Screen metal that stands up to heat and weather
The code also asks that a spark arrestor screen resist heat and corrosion to a set standard. Thin, light mesh can burn through near the flue or rust through in the weather. Once holes open up, the screen no longer stops sparks or animals.
We look closely at the screen on your existing cap for burned patches, rust holes and torn edges. A screen that has failed while the lid and frame are sound may be replaceable on its own, if the maker offers the part. Otherwise, we explain why the whole cap should be replaced rather than patched with generic mesh.
A written record of the cap work
After the job, you receive a written record of the work. It names the cap, the metal, the screen and the fastening method, along with any repairs done at the same time. It also notes what we saw but did not repair, such as a crown crack you chose to handle later.
Keep that record with your house papers. It helps anyone who works on the chimney after us, and it helps you if the house is sold. If you had a free inspection without going ahead, you still keep the free written estimate and the findings it lists for your home in Fisher Island.
When another company recommended a new cap
Sometimes we hear from someone after another company has recommended a new cap. A second opinion is reasonable, especially if the reason given was vague. We look at the cap and the chimney top ourselves rather than simply repeating the earlier advice.
Share the earlier estimate if you are comfortable doing so. We explain where we agree, where we see things differently and why. Our free written estimate stands on its own, so you can compare both and choose. If the cap does not need replacing, we tell you that plainly.

Before you replace a chimney cap in Fisher Island
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.
Should the crown be fixed before the cap is replaced?
If the crown is cracked where a multi-flue cap would fasten, yes, or the cap ends up mounted on a weak surface. We describe the crown during the free inspection and price that repair as a separate item.
Can you replace just the screen on my cap?
Where the maker offers a replacement screen and the rest of the cap is sound, that can be enough. A piece of generic mesh is not the same thing, because the opening size affects both sparks and draft.
