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 serviceWhen Lansdowne homeowners light the first fire of the season, they are trusting a flue nobody has looked inside since last winter. The housing here — resort-style subdivisions of large colonials near the Potomac — sets the chimney workload in Lansdowne. Because Lansdowne is about 31 miles from our Beltsville headquarters, route days here run several times a week in season.
Lansdowne is about 31 miles from our Beltsville headquarters — typically a 70-minute drive in normal traffic. Every ZIP in 20176 is inside our standard pricing map; the price quoted is the price charged, with no distance surcharges. Every visit is documented with photos before and after, and the findings are written up the same day.

Wood stoves around Lansdowne run long, low burns that coat liners with creosote faster than open fireplaces do, and many were installed into oversized masonry flues that cool the exhaust and speed the build-up. A right-sized insulated stainless liner transforms both safety and performance. We scan first, size the liner to the stove's actual flue collar, and show you the before-and-after camera footage. The camera does not guess, and neither do we — the scan settles what the flue actually holds. Left alone for another season, it rarely stays the same size of problem.
One more thing Lansdowne customers get on every ticket: a named technician, an arrival window we keep, and a written record of the work — the same standard on a cap install as on a full relining.

Camera scans for home sales, insurance files and post-fire checks across Loudoun County — photo reports in writing.
Factory-built units need panels measured, dampers freed and chase covers checked — the Lansdowne subdivision specialty our crews run weekly.
The full rotary sweep, HEPA-contained, ends with a camera look up the flue — the Lansdowne visit most homes book every fall.
Fall in Lansdowne 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.
Mid-winter in Lansdowne 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.
Chimney swifts return to Loudoun County in spring, and an uncapped flue in Lansdowne is prime nesting real estate. Spring is cap season — before the birds file their claim.
Dry summer weeks are when waterproofing and crown coats actually cure to spec. Lansdowne chimneys sealed in July shrug off the fall rains that find every crack in October.

“It was a pleasure to work with Eagle Chimney Service — from scheduling, to explaining all of the steps beforehand, to the day of the visit. They saved me money by teaching me how to keep a healthy flame and the right way to pack new sand when it arrives.”

Geography helps Lansdowne: Ashburn is the next stop on most runs, with Poolesville and Broadlands close behind, so a crew is rarely more than a few miles away on route days. That density is also why emergency calls from Lansdowne get answered by a local truck instead of a call center. Measured from the center of Lansdowne, the nearest stops are Ashburn (about 3 miles), Poolesville (about 4) and Broadlands (about 6) — straight-line distances, before the truck's actual route.
