Damper Repair & Replacement
Throat damper repair and top-sealing damper installation — stopping the draft, the drips and the energy loss at the flue's door.
About this serviceFrom the outside, a Occoquan chimney is brick and a cap. Inside, it is a heat-and-exhaust system that ages with every fire — and it ages fastest when nobody checks it. The housing here — historic mill-town homes and riverfront properties on the Occoquan River — sets the chimney workload in Occoquan. Because Occoquan is about 32 miles from our Beltsville headquarters, route days here run several times a week in season.
Occoquan is about 32 miles from our Beltsville headquarters — typically a 75-minute drive in normal traffic. Coverage here spans 1 ZIP codes (22125), all dispatched from the same Beltsville shop that answers the phone. Every visit is documented with photos before and after, and the findings are written up the same day.

Plenty of Occoquan households burn several nights a week once the cold sets in, and steady burning lays down creosote faster than the once-a-season fire people picture. By the second or third season that layer can glaze — the hard, shiny stage that brushes alone cannot fully remove and the stage most likely to ignite. Our Prince William County sweeps read the deposit before choosing tools, and the camera scan afterwards shows exactly what came off the flue walls. This is our standard approach: inspect on a schedule, repair on evidence. The fix is usually a fraction of the cost of the damage it prevents.
We are a chimney-only company — sweeps, scans, masonry and liners are the whole business, and it shows in the questions we ask and the photos we bring back down the ladder.

The full rotary sweep, HEPA-contained, ends with a camera look up the flue — the Occoquan visit most homes book every fall.
Nests and the occasional raccoon, removed humanely and legally — then a scan to prove the flue is clear and a cap to keep it that way.
Joints cut out and repointed with matched mortar; spalled brick replaced on Prince William County stacks of every era.
The first frost is Occoquan's chimney deadline: caps checked, flues swept, crowns sealed before freeze-thaw starts its work on Prince William County masonry.
Mid-winter in Occoquan is no time to discover a blocked flue. Burn dry, seasoned hardwood, keep the damper routine consistent, and call at the first sign of smoke spilling into the room.
Spring cleaning in Occoquan should include the flue: a winter of ash and soot left in the firebox corrodes metal and stinks up the house on humid days. We vacuum it out and close the season properly.
Summer is the cheapest chimney season in Occoquan: masonry cures properly in the warmth, relining and crown work book faster, and nobody is racing a cold house.
