From flue check to working damper in Roosevelt Gardens

Routing the cable down the flue

The cable is fed from the lid down through the flue until it reaches the fireplace. On the way, it passes the smoke chamber and the throat, where the old damper frame and the smoke shelf can catch it.

We guide the cable so it hangs clear of sharp edges and does not rub on the old damper plate. Where a snag point cannot be avoided, we explain what we did about it. A cable that runs clean opens and closes the lid smoothly for longer, and it is less likely to fray.

Outside noise through the flue

An open flue carries sound as well as air. Traffic and wind can be heard more clearly near a fireplace with no working damper. One maker lists reducing outside noise among the benefits of its top damper.

We mention that as a side effect, not a promise. How much difference you notice depends on the house and the surroundings. If noise is part of the reason you are asking, tell us, and we explain honestly what a sealed flue top can and cannot change.

Checks once the damper is fitted

Before we leave, the damper is opened and closed several times from the handle. We watch the lid from the roof for a full opening and an even close. The bracket is tested for movement, and the cable is checked for rubbing along its route.

We also confirm that the old throat damper cannot swing into the smoke path. Anything that still concerns us goes into the written record. You should find the damper working as described the first time you use it.

A lid that taps or rattles in wind

A properly set damper sits firmly shut. Tapping at the top of the flue on windy days often means the lid is not pulled down tight. The lug may have slipped, or the hinge may have worn.

Note when you hear it and whether the handle is locked at the time. We check the lug setting, the gasket and the hinge. Often a small adjustment fixes it. If the hinge has worn loose, a replacement part or damper may be needed, and we explain which.

Before you add a top damper in Roosevelt Gardens

How does the 72-hour inspection discount apply to a damper?

It starts at your own free inspection. Damper work, and any other service on that estimate, approved inside 72 hours of it is 10% off. After that, the estimate stands at its written price.

Can I fit a top damper myself?

One maker's instructions recommend professional installation, and the work happens on the roof and inside the firebox. We would rather you stayed off the roof. If you have already bought one, we can check whether it suits your fireplace.

What if my chimney has more than one flue?

The damper goes only on the flue that serves the fireplace. Other flues keep the termination their own appliances call for. We identify each flue before recommending a damper or cap for any of them.
