How our crew installs top dampers in Johnson Village
Details our Johnson Village team explains on every top damper visit.
Planning a gas conversion later
If you are thinking about adding a decorative gas appliance in a year or two, say so before choosing a damper. That appliance's instructions may call for a permanent opening, and a sealing top damper would then need to come off or be fixed open.
Knowing your plans lets us recommend the right step now. Sometimes that means a top damper for the years of wood fires ahead, and sometimes it means repairing the throat damper and waiting, with both choices laid out in writing. Whatever you decide, the reasoning goes into the estimate so it is there when the gas question comes up again.
The adhesive bead that holds the frame
Top dampers are usually glued to the tile with the maker's high-temperature adhesive. The Lock-Top instructions call for a 1/4 inch bead of the supplied adhesive around the top of the opening, the damper centered and pressed down firmly, and any gaps filled for a proper seal.
We follow the instructions for the model you choose, which is why the product is named in your estimate. A continuous bead with no gaps is what keeps rain and air from sneaking under the frame. The bead is checked all the way around before the damper is left to cure.
Running the cable down the flue
The cable is fed down the inside of the flue before the frame is set, then pulled through the throat into the firebox. It has to run freely, without snagging on ledges, a throat plate or rough mortar.
Once the damper is set, the whole run is tested by working the lid several times from the firebox. A cable that drags or catches is rerouted before we leave, so the lid opens and closes the same way every time. The route is also checked with any throat plate in its final position, so nothing changes after we leave.
The gasket that makes the seal
The lid of a top damper closes against a gasket rather than bare metal. One retailer's listing for the Lyemance damper describes a high-temperature silicone gasket on the flap that seals against downdrafts, moisture and insects.
A clean, soft, unbroken gasket is what makes the damper worth fitting. We check it at installation, and on older top dampers we look for hardening, cracks or gaps that let light show through with the lid closed. A damaged gasket on an otherwise sound damper can often be replaced without changing the whole unit.

What Johnson Village homeowners ask about top dampers
Straight answers from our specialists in Johnson Village, with no sales pressure.
When can I close the damper after a fire?
Only once the ashes are completely cool. The Consumer Product Safety Commission advises keeping the damper open until then and never closing it at bedtime over warm ashes.
Does a top damper need maintenance?
Very little. A yearly check of the gasket, cable, spring and bracket keeps it reliable, and the clamp may need re-setting if the cable stretches. We can do that during a yearly chimney inspection.
