Top damper installation, step by step, for Lake Avalon homes
Practical notes from the damper installers serving Lake Avalon.
Measuring the flue before ordering
Each top damper is sold to fit a specific flue size, so we measure the outside and inside of the tile at the top, note whether it is square, rectangular or round, and check how far it stands above the crown.
Those numbers go into the estimate beside the model we propose. Ordering from a guess made in the yard is how a frame ends up overhanging a rim it cannot grip or sitting inside a tile it cannot seal against. The measurements are kept in your records, which helps if the damper ever needs parts or replacing.
Setting the clamp for a tight seal
The seal depends on how firmly the lid is pulled down. In the Lock-Top instructions, the adjustment clamp is slid up the cable to the bracket, the cable is pulled to close the damper, and the clamp is set for the tightest seal.
We set the tension, then check the closed lid from the roof to confirm it sits evenly on its gasket. Too little tension leaves gaps, while too much strains the parts, so the setting is checked rather than guessed. The clamp setting is noted, so a later adjustment starts from a known point.
Keep it open until the ashes are cool
The Consumer Product Safety Commission advises keeping the damper open until the ashes are cool, because an open damper prevents poisonous gases building up inside the home.
Because a top damper makes the flue so easy to close, this rule matters all the more. Leave the handle released until the ashes are fully cold, then pull it down and lock it at the bracket. If you are unsure whether the ashes are cold, leave the lid open until morning.
Our 100% satisfaction guarantee
We want the damper to open when you release the handle, close firmly when you lock it and make sense to everyone in the house. If something about the installation is not right, tell us and we will make it right.
That promise comes from a family-owned business that depends on local word of mouth. It is backed by the written scope, so both of us know exactly what was agreed. A follow-up call after the first few fires is welcome, and so are any questions that come up.

Answers about top-sealing dampers for Lake Avalon homeowners
Our family-owned team in Lake Avalon answers the damper questions homeowners raise before booking.
Can a top damper go on a factory-built fireplace?
Only where the fireplace maker lists a damper or termination part for that system. The top dampers we install bond to masonry flue tile. We check your fireplace's documentation and explain what it allows.
Is the damper inspection really free?
Yes. We check the fireplace, the throat damper, the flue top and the crown at no charge and give you a written estimate. There is no obligation to book.
