Level 1 sweep and inspection to the NFPA 211 annual standard - flue, crown, cap, and flashing checked and photographed
Chimney sweep logs do not sweep chimneys. They loosen some creosote - which then falls where a brush and vacuum still have to collect it.

AfterFast, Reliable Chimney Inspection Across Washington
Most Washington chimneys are over a century old, built for coal, and now asked to do a job they were never designed for - which is why our Chimney Sweep in Washington starts every service with a camera-based inspection. That’s exactly why a camera-based chimney inspection in Washington, DC isn’t optional for rowhouse owners – it’s the only way to know whether your flue is safe before you light a fire or turn on a gas appliance. We serve every ward in Washington, from Capitol Hill to Georgetown to Petworth, with inspections scheduled at your convenience. Schedule yours at (336) 863-3889, and you’ll get a written price before any work begins.
Why Alcott Chimney Sweep Is Washington’s Preferred Chimney Inspection Company
Since 2002, we’ve been inspecting chimneys across Washington’s rowhouse blocks and apartment conversions. We know what a party-wall stack looks like, what an abandoned coal flue hides, and why a chimney crown built in 1920 is failing after a hundred winters of DC freeze-thaw cycles. That local knowledge means we don’t waste your time quoting problems you don’t have – and we don’t miss the ones you do.
Every technician who arrives at your Washington home is background-checked and identity-verified under the Threshold Standard. You’ll know the technician’s name and see their photo before we arrive, and they’ll show a photo ID badge at your door. No exceptions. Ever.
We also put our work in writing. Every repair carries a written guarantee, and the 365-Day Done Right Promise means if a repair fails within the coverage period, the second visit is free. Washington homeowners call us back because we show our work on camera. Not because a sales rep told them to trust us.
Chimney Flue Inspection in Washington
A Chimney Flue Inspection in Washington means documenting the actual condition of the passage your smoke and exhaust travel through – the clay tile, brick, or mortar surface inside the stack. In Washington’s rowhouses, that flue was often built for coal smoke, not wood. A camera inspection in Washington typically runs $189 – $349 depending on the level and whether we’re tracing one flue or multiple flues in a shared stack.
You need one before you burn a single fire in a recently purchased home, before converting a decorative fireplace back to wood, or if you smell something odd when a gas appliance runs. After you’ve watched the footage, you’ll know exactly what’s urgent and what can wait.
Camera Documentation
We run a camera through every flue during an inspection and you watch the footage with us on site. What you see is what we base every recommendation on. No camera, no recommendation – that’s the rule. If a chimney company quotes you a full reline on a Washington rowhouse without running a camera first, that’s a sign to get a second opinion.
Multi-Flue Tracing
Many Washington stacks hold two or three flues. We trace each one from firebox to cap. That’s how we catch the abandoned coal-furnace flue, the unlined gas-appliance flue, and the owner’s assumed wood-ready fireplace flue all in one chimney inspection.
Chimney Fire in Washington
A Chimney Fire in Washington is most often the result of creosote – the tar-like buildup that forms when wood smoke cools and condenses inside the flue – igniting inside a century-old masonry stack that was never designed for wood heat. We’ve inspected enough Capitol Hill rowhouses off East Capitol Street to know what that looks like on camera before it becomes a fire call: glazed, second-degree creosote coating a clay-tile liner that’s already offset at the roofline.
If you suspect a chimney fire has already occurred – loud cracking sounds, dense smoke, a strong hot smell – call DC Fire and EMS first, then call us at (336) 863-3889 for a Level 2 inspection before anyone uses that chimney again. A post-fire chimney inspection in Washington runs $349 – $649 depending on the flue count and whether we’re documenting a full stack or a single fireplace flue.
Creosote Staging
We classify creosote by degree. First-degree is dusty soot that sweeps off. Second-degree is flaky, crusty, and needs rotary tools. Third-degree is a hard, glazed tar that can’t be swept – it usually signals a flue overheating and often requires resurfacing. We’ll show you each degree on camera so you’re not taking our word for it.
Post-Fire Assessment
After any chimney fire, we inspect the flue for cracked tiles, separated mortar joints, and warped or displaced components. You get camera stills and video showing exactly what the fire did. The written price for any repair work comes before we start. Never after.
Trusted Brands We Service in Washington
Washington homeowners don’t call us for box-store substitutes. We carry and install the professional-grade trade materials chimney pros specify: HeatShield for flue resurfacing, Gelco chimney caps and chase covers, and Olympia Chimney liners and components. Stacked inventory locally means we don’t wait a week for a crown to ship. When a gas-appliance flue in a Capitol Hill rowhouse needs a liner, the material is here and the job gets scheduled – not deferred.
Common Chimney Inspection Problems We See in Washington Homes
- Abandoned coal-flue stacks marked as wood-ready. The chimney that originally vented a coal furnace is now uncapped and open to rain, and the owner assumes the fireplace flue next to it is fine. It isn’t – not until we’ve put a camera through it and proven it.
- Offset clay-tile liners at the roofline. A century of DC’s freeze-thaw cycles shifts clay tiles at the roofline joint, and an offset liner is a carbon monoxide pathway. We see this most often in Georgetown and LeDroit Park rowhouses.
- Gas appliances venting into unlined masonry. A mid-century gas conversion often vented the furnace or water heater into the old coal flue with no liner. On camera, that flue looks like crumbling brick and mortar. We flag it and quote a repair, but we show the footage before you spend a dollar.
- Spalling chimney crowns on single-wythe brick. Washington’s oscillating around 32°F all winter means water freezes in the crown, expands, and breaks the brick apart. Pieces fall, water gets in, and the flue behind it deteriorates faster. It’s a DC rowhouse problem, not a generic chimney problem.
Pricing for Chimney Inspection in Washington, DC
A standard Level 1 chimney inspection in Washington runs $189 – $279 when the chimney is already clean and accessible. A Level 2 inspection – the one you want when buying a rowhouse, after a chimney fire, or before converting a fireplace back to wood – runs $349 – $649 depending on how many flues run through the stack. If you’re on Capitol Hill with a three-flue chimney, expect the higher end: we’re tracing and filming three separate passages, not one.
What changes the price: flue count, roof access, whether we’re hoisting a camera through a steep DC slope, and whether Historic Preservation Office coordination is needed before we touch the exterior masonry. You get the written price before we start. Always. Call (336) 863-3889 for a free estimate.

FAQs About Chimney Inspection in Washington
Almost always no, not without a Level 2 inspection first. Washington’s pre-1930 rowhouse stacks were sized and drafted for coal, not wood. If the flue still has its original clay-tile liner, it’s likely cracked, offset, or missing a cap after a century of freeze-thaw cycles. If it was abandoned when the coal furnace left, it may be uncapped and open to water. Call (336) 863-3889 and we’ll run the camera before you burn anything.
Because Washington rowhouses share party walls, and a cracked, unlined flue can allow carbon monoxide to migrate through deteriorated mortar into the neighboring unit – not just your living room. That’s why a thorough chimney inspection in Washington means tracing every flue in a shared brick column, not just the one you think is active. If you’re in a party-wall home and haven’t had your stack inspected, call us for a camera-based Level 2 inspection.
Often yes. Large parts of Capitol Hill, Georgetown, LeDroit Park, and Petworth fall under DC Historic Preservation Office jurisdiction. Exterior masonry work on a chimney crown, cap, or flashing can require HPO coordination before a contractor touches it. We handle that coordination, but the approval is a real step, not a formality. We’ll tell you on the inspection report whether your address needs it.
Every 24 months at minimum, because your gas-appliance flue is venting through the same century-old stack as your neighbor’s. DC’s high year-round humidity accelerates moisture intrusion into cracked flue tiles, and freeze-thaw cycles work the exterior masonry year-round. An inspection every two years catches deterioration before it becomes a carbon monoxide problem. Call (336) 863-3889 to schedule.
First-degree is light, dusty soot that sweeps off. Third-degree is a hard, glazed tar that can’t be swept and usually indicates the flue has already overheated. In Washington’s rowhouse stacks, third-degree creosote on an old clay-tile liner is a red flag: the liner is often already cracked underneath. We show you the degree on camera and only recommend what you can see. If you haven’t had a camera-based chimney inspection, start with a call to (336) 863-3889.
