Smoke that rolls out of the opening

Smoke rolling out from the first match can come from a damper that stops partway. The plate looks open from below, yet it stops short of its full travel, so the passage above the fire is smaller than the flue it feeds.

We measure how far the plate actually opens and compare it with the throat. A bent stop, a warped plate or a crank that runs out of thread can each hold it short. Once the plate swings all the way back, the smoke usually goes where it should. Fireplace smoking in St. Nicholas? Call (904) 920-5495 and our damper specialists will test it for free.

Old dampers in St. Nicholas fireplaces

Damper wear depends on the fireplace's age and use rather than the town. A frame that has been heated for many seasons shows it in pivot wear and small cracks.

We grade the frame on every St. Nicholas visit so you know whether a new plate is worth fitting to it.

Cast iron plates and stamped steel plates

Throat damper plates come in two broad kinds. Heavy cast-iron plates hold their shape well under heat and rust slowly because of their thickness. Stamped steel plates are lighter and cheaper to make, and they give less warning before rust eats through them.

Both are ferrous metal, which is what the code asks for. The difference shows up in the repair: a cast plate that has only scaled can usually be cleaned and kept, while a thin steel plate with pitting along the edge rarely justifies the effort. We name which kind you have on the estimate, because it decides whether freeing it is worth the labor.

Worn pivot holes and a floating plate

The holes the pivots ride in wear with every opening and closing. When they wear oval, the plate sits lower on one side, stops meeting its seat evenly and can lift and tap in a gusty wind.

A plate with worn holes in a sound frame can often be replaced alone, because the new plate brings new pivot points. When the wear is in the frame's lugs, the frame is the part that has failed, and a new plate will float just like the old one. We check both before ordering anything, so the part that goes in solves the rattle and the leak together.

Using the fireplace while a part is on order

Some damper repairs need a part ordered, a matched plate or a control assembly that fits the frame. Whether a fire can be lit while you wait depends on where the plate is stuck.

A plate held fully open lets a fire burn safely, though room air escapes between fires. A plate stuck closed or partway closed means no fire until the repair is done. Where we can, we leave the plate secured fully open so the fireplace stays usable while the part arrives, and we tell you which situation you are in before we leave the house.

Damper questions from St. Nicholas homeowners

Will a new plate do, or does the whole damper go?

A new plate is enough when the frame is flat, uncracked and has sound pivot lugs, and a matching plate is still made. If the frame has failed, the whole damper is replaced or a top seal is fitted instead.

How long does a damper replacement take?

Freeing or rehanging a plate is usually done in one visit. Cutting out a frame and setting a new damper takes longer, and the refractory mortar needs its cure time before the first fire, which the estimate states.
