A spring that will not lift the lid
A spring lifts the lid of a top sealing damper, and the cable pulls it down. A spring that has rusted, lost tension or come off its mount leaves the lid half open, which spoils the draft of the next fire. A lid stuck halfway also catches rain and debris without sealing anything.
We replace springs and hinge parts on top dampers in Mayport with the maker's parts, check that the lid opens fully when the cable is released, and show you how to confirm that before lighting.
Mayport is a neighborhood inside Jacksonville city limits. The county for Mayport is Duval County.

Open fully before every fire
Above everything else, a top damper has to be fully open before a fire is lit. A fire under a closed lid sends smoke and carbon monoxide into the room. The handle position shows whether the lid is open, and a look up the firebox confirms it.
The makers also say to leave it open until no fire remains and the ashes have gone cold. Closing it early on smoldering embers traps their smoke in the house. We cover both points at the walk-through, and write them on the ticket. A lid that is only partly open can also spill smoke, so the check is for fully open, not just unlocked.
Keeping animals out of a closed flue
A closed top damper shuts the flue opening, so birds and animals cannot move in while the fireplace is idle. While the lid stands open during a fire, heat and smoke keep animals away from the flue.
Anything already living in the flue has to be removed before the damper is fitted, and some birds and bats are protected by wildlife rules that set the timing. We check the flue before fitting and tell you if that step comes first. Where the chimney also carries an appliance flue, that flue keeps its own screened cap against animals.
Stopping odors from an idle fireplace
The smell of old soot in a room with a cold fireplace comes from air moving down the flue and across the deposits on its walls. The stronger the pull from the house, the stronger the smell.
Closing the flue at the top stops that movement, and a sweep removes the deposits that give off the smell. We check both and say which one your fireplace needs more. A top damper also keeps rain from wetting old deposits, and wet soot smells stronger than dry.

Top damper questions from Mayport
Can a top damper go on any chimney?
It needs a masonry fireplace flue with a sound tile standing high enough above the crown. Flues for other appliances and listed metal chimneys are handled differently, and we tell you which applies.
Is the top damper install guaranteed in Mayport?
Yes, the installation we quote is covered by our satisfaction guarantee. If the lid does not seal or open the way we showed you, we come back and set it right.
