Stainless steel, copper and multi-flue caps with animal guards and spark arrestors — measured, fitted and warrantied.
About this serviceFireplaces in Dunn Loring earn their keep on the coldest weeks of the year — and they ask for one honest inspection a year in return. The housing here — split-levels, ramblers and colonials from the postwar building wave — sets the chimney workload in Dunn Loring. The drive from our Beltsville shop is routine for our crews; Dunn Loring addresses batch with the rest of the Fairfax County run.
Dunn Loring is about 21 miles from our Beltsville headquarters — typically a 50-minute drive in normal traffic. The full ZIP list for this page — 22027 — 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.

The concrete crown is the chimney's roof, and across Fairfax County it is the part that fails first: poured thin, cracked by freeze-thaw, it funnels water straight into the brick core below. By the time white efflorescence or spalling shows on the Dunn Loring chimney's face, the crown has usually been leaking for seasons. We rebuild crowns with a proper overhang and drip edge, or seal sound ones with a flexible crown coat — matched to what the inspection actually finds. The fix is usually a fraction of the cost of the damage it prevents. Left alone for another season, it rarely stays the same size of problem.
One more thing Dunn Loring 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.

Factory-built units need panels measured, dampers freed and chase covers checked — the Dunn Loring subdivision specialty our crews run weekly.
The full rotary sweep, HEPA-contained, ends with a camera look up the flue — the Dunn Loring visit most homes book every fall.
When tiles crack, the durable answer is an insulated stainless liner sized to the appliance — scanned before, scanned after, warranted in writing.
The first frost is Dunn Loring's chimney deadline: caps checked, flues swept, crowns sealed before freeze-thaw starts its work on Fairfax County masonry.
When Fairfax County temperatures drop hard, Dunn Loring fireplaces run nightly — and heavy-use weeks are exactly when creosote and draft problems announce themselves. Emergency dispatch stays 24/7 all winter.
Spring is when winter's damage shows: crown cracks opened by freeze-thaw, flashing lifted by storms, nests started in open Dunn Loring flues. A spring inspection prices repairs while they are still small.
The Dunn Loring households that plan ahead use summer for the big work — liners, rebuilds, waterproofing — when Fairfax County schedules are open and mortar sets the way it should.
