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 serviceFireplaces in Colesville earn their keep on the coldest weeks of the year — and they ask for one honest inspection a year in return. The housing here — tree-lined subdivisions and older village centers — sets the chimney workload in Colesville. The drive from our Beltsville shop is routine for our crews; Colesville addresses batch with the rest of the Montgomery County run.
Colesville is about 4 miles from our Beltsville headquarters — typically a 15-minute drive in normal traffic. The full ZIP list for this page — 20904, 20905 — is checked against the route map every morning before trucks roll. Every visit is documented with photos before and after, and the findings are written up the same day.

Plenty of Colesville fireplaces were converted to gas over the years, and the flue above them was simply forgotten. Gas exhaust is cooler and wetter than wood smoke — it condenses inside clay liners, eats mortar from the inside, and carries carbon monoxide that must never find a crack to leak through. Converted systems need inspection like any other, and ventless or vented questions are ones we answer with the appliance manual and a CO meter, not opinions. Every finding is photographed, because 'trust us' is not documentation. The fix is usually a fraction of the cost of the damage it prevents.
Booked work comes with photo documentation as standard: the flue on camera, the cap and crown from the roof, and the findings written down where you can keep them.

Rotary brushes, HEPA containment and a camera finish: the standard Colesville sweep, documented top to bottom.
The full NFPA Level 2 protocol — camera in the flue, attic and clearances checked — reported with photos for Colesville buyers, sellers and insurers.
Stainless caps measured and fitted on Colesville rooftops — birds, raccoons and rain stay outside where they belong.
There is a reason Colesville regulars book their sweep in early fall: the work is identical in November, but the calendar is not. Same crew, same camera — just a slot that still exists.
Winter is when a marginal chimney in Colesville becomes an urgent one. If the fire suddenly burns lazy or the room smells of smoke, that is the flue asking for a scan, not another log.
Spring cleaning in Colesville 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.
The Colesville households that plan ahead use summer for the big work — liners, rebuilds, waterproofing — when Montgomery County schedules are open and mortar sets the way it should.
