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 serviceAsk a Overlea homeowner when their flue was last scanned with a camera and most cannot say. That gap is exactly where chimney fires and carbon-monoxide leaks come from. The housing here — brick rowhomes, duplexes and bungalows in an established streetcar suburb — sets the chimney workload in Overlea. The drive from our Beltsville shop is routine for our crews; Overlea addresses batch with the rest of the Baltimore County run.
Overlea is about 29 miles from our Beltsville headquarters — typically a 65-minute drive in normal traffic. The full ZIP list for this page — 21206 — 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.

Two-storey stacks and exposed rooflines around Overlea make draft a local science: wind over the ridge, a flue that ends below the highest roof point, or a house sealed tight by new windows can all push smoke back into the room. We measure the stack against the 3-2-10 rule, check the damper and smoke shelf, and fix the geometry or the cap — not with guesses, but with the cause identified on camera. It is also the kind of problem that gets cheaper the earlier it is caught. Insurance files and home-sale paperwork both go smoother with that photo record attached.
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.

Repointing with mortar matched to the original — the difference between a repair that lasts decades on a Baltimore County stack and one that eats the brick.
Humane removal and a clear-flue scan afterwards — then a cap so Overlea critters cannot re-book the flue.
The two leak points we repair most in Overlea: cracked crowns above, tired flashing at the roofline.
Fall in Overlea means the phone rings off the hook — every cold morning books out the week. The households that swept in September watch the rush from beside a working fireplace.
A Overlea winter runs on seasoned wood and a clean flue. Wet or green wood is the fastest creosote builder there is — if the woodpile is questionable, the sweep matters even more.
Spring cleaning in Overlea 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 Overlea: masonry cures properly in the warmth, relining and crown work book faster, and nobody is racing a cold house.
