What goes into a top damper job in Fisher Island
One damper among several flues
On a chimney with several flues, a multi-flue cap may cover all of them. A top damper, by contrast, seals only the fireplace flue and needs its own space to open. The two can conflict if the cap sits too low.
We look at how the flues are arranged and what covers them now. Sometimes the damper fits under the existing cap. Sometimes the cap has to be raised or changed to give the lid room. We explain the arrangement and list any cap work separately from the damper.
The crown around the damper
The damper sits on the flue, but the crown around it still sheds water off the chimney. A cracked or crumbling crown can let water into the masonry even with a sealed damper above the flue.
We look at the crown during the damper inspection and tell you what we see. Crown repair is quoted as its own item, so you can decide on it separately. A damper does not waterproof the crown, and we would rather tell you now than have you discover it with the first heavy rain.
Workmanship warranty and product terms
Our workmanship warranty covers the installation we carry out: the bond to the tile, the cable route, the bracket and the seal setting. We go through what it covers with you before you agree to the work.
The damper itself usually comes with its maker's own terms. We pass those on with the written record. If something goes wrong later, describe it to us. We look at whether it is an installation issue, a product fault or wear from use, and explain what happens next.
When we advise against a top damper
Some fireplaces are poor candidates for a top damper, and we tell you so. The usual reasons are a gas appliance in the firebox or a flue that also vents another appliance. A factory-built chimney whose maker does not allow it, or a flue top that cannot hold a frame, are others.
In those cases, we explain what else can be done, such as a throat damper repair, a cap or leaving the arrangement as it is. You receive that advice in writing. We would rather lose a sale than fit a damper that works against the fireplace.

Top sealing damper FAQs for Fisher Island
Can I add a top damper if gas burns in the firebox?
Usually not with the common products. A vented decorative gas appliance needs the damper held fully open while it burns, and several top damper products are marked not for that use. We read both sets of instructions before giving you an answer.
Does a top damper replace my old throat damper?
It takes over the job of closing the flue. The old throat damper is then fixed open, removed or left in place, depending on its condition and the fireplace. We explain which applies and list it on the estimate.
Will a top damper lower my cooling or heating bills?
One maker's instructions say a closed damper keeps conditioned air from escaping up the flue. We do not promise a savings figure, because that depends on the house and how the fireplace is used. We recommend a damper for fit and function.
