The damper controls airflow through your chimney. When it’s stuck open, your conditioned air pours straight up the flue — costing hundreds in wasted energy per year. When it won’t open properly, smoke backs up into your living room. We repair and replace both throat dampers and top-sealing dampers for Allen homeowners. Call (972) 521-7225.

When a throat damper fails beyond repair, we recommend upgrading to a top-sealing damper. Top-sealing dampers sit at the top of the flue and are operated by a stainless steel cable running down to the firebox. They seal better than throat dampers, double as a rain cap, and last 20+ years. It’s a better product in every way.
We check the damper during every chimney sweep and inspection. If yours isn’t working right, we’ll let you know and quote the fix on the spot. If smoke still comes back into the room after the damper is fixed, our fireplace downdraft repair and chimney fan installation services find and fix the cause.
Throat damper repair (lubrication, handle, hinge): $150–$350. Top-sealing damper installed: $300–$600. The top-sealing option replaces the throat damper entirely and also serves as a chimney cap, so you’re getting two products in one.
If the frame is intact and the damper plate just needs lubrication or a handle, repair is fine. If the plate is warped, the frame is cracked, or the damper is severely rusted, replacement is better. In most cases, we recommend upgrading to a top-sealing damper — it costs a bit more than a throat damper repair but lasts longer and seals better.
It’s a damper that mounts at the top of the chimney instead of inside the firebox. A stainless steel cable runs down the flue to a handle or bracket in the firebox. When closed, a silicone gasket creates an airtight seal. It also works as a chimney cap, keeping rain and animals out.
Most gas fireplaces have a damper, but it should be locked open or removed entirely per manufacturer requirements. Gas fireplaces need constant ventilation when in use. If your gas fireplace damper is closing accidentally, that’s a safety hazard — call us to inspect it.
