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.

AfterChimney Cleaning in Washington, DC
Chimney cap and crown work in Washington, DC is shaped by one fact more than any other: most of the District’s housing stock is brick rowhouses built between 1880 and 1930, and their chimney crowns are original. That means cracked crowns, missing caps, and water intrusion are not exceptions here. They are the default finding on a first inspection. Call (240) 220-9395 and we’ll put a camera down your flue before we recommend anything.
Why Washington Homes Are Different
Washington’s rowhouses were built for coal. The flues are clay tile, the mortar is lime-based, and the crowns were poured before modern expansion joints existed. Then came gas conversion, then central heat, and nobody relined the chimneys. Today a typical Capitol Hill or Shaw rowhouse has a single exterior stack serving two to four flues, shared party walls, and a crown that has been absorbing 20 to 30 freeze-thaw cycles every winter for a century. The soft Roman brick and lime mortar on pre-1940 chimneys spall badly under that cycling, so crown and mortar deterioration shows up on nearly every inspection we do in Washington.
There is a second layer here that does not exist across the river in Arlington or Silver Spring: DC’s historic preservation districts. Georgetown, Dupont Circle, Logan Circle, Capitol Hill, and Shaw all fall under the Historic Preservation Office, and exterior masonry work, cap replacements, and crown repairs often require coordination with HPO before work begins. That is not a complication to dodge; it is a process we know well and handle as part of the job.
Our Main Washington Services
Washington homeowners call us most often for two things: the annual sweep and the repairs that follow what the camera finds. Here is how each works in the District.
Chimney Cleaning & Sweep in Washington
A proper sweep in Washington starts with identifying which flue serves which appliance. In a shared rowhouse stack, that matters more than in a detached suburban house, because sweeping the wrong flue does nothing for the fireplace you actually use. Our camera-scan inspection is NFPA 211 Level 2 and the photo record is standard on every visit, not an add-on. More detail is on the Chimney Cleaning & Sweep in Washington page.
Chimney Repair in Washington
Repair work here usually means crown repair, mortar repointing, smoke chamber parging, or flue tile replacement. The freeze-thaw cycling in Washington means small crown cracks become wide ones in two or three winters if ignored. We write the scope and the price before anyone starts, and the photo record shows you exactly what we found and what we did. See the Chimney Repair in Washington page for the full breakdown.
Fireplace Services in Washington
Washington’s older homes often have fireplaces that were sealed off during gas conversion and are being reopened by new owners. That means checking the firebox, damper, smoke shelf, and flue before the first fire. We also handle gas log installation and fireplace rebuilds. The Fireplace Services in Washington page covers what to expect.

BeforeAfterChimney Cap & Crown in Washington
A cracked or missing chimney crown is the single most common cause of water damage in Washington rowhouse chimneys, and water is what turns a $400 repair into a $4,000 rebuild. Here, the original crowns on 1880 to 1930 rowhouses were poured with no expansion joint and often no proper overhang, so water runs straight down the brick face. Freeze-thaw cycling does the rest. Whether you need a stainless cap, a multi-flue cap for a shared stack, or a full crown recast, this is the work that keeps everything else standing. For the full service breakdown, see Chimney Cap & Crown.
Cap Installation
Signs you need it
You can see daylight through the top of your flue, or birds and squirrels are getting in.
What it costs in Washington
Cap installation in Washington typically runs $180 to $480 depending on flue size and cap material.
How we do it
We measure the flue, match the cap to your stack, secure it with stainless hardware, and photograph the finished install.
Crown Repair
Signs you need it
Hairline cracks, spalled brick at the top of the chimney, or water staining on the ceiling near the fireplace.
What it costs in Washington
Crown repair in Washington typically runs $350 to $900 depending on crack severity and crown size.
How we do it
We clean the crown surface, fill and seal cracks with the right material for DC’s freeze-thaw load, and document before and after.
Multi-Flue Cap
Signs you need it
Your rowhouse stack has two or more flues exposed to rain, and single caps keep blowing off or failing.
What it costs in Washington
Multi-flue cap work in Washington typically runs $400 to $950 depending on total stack dimensions and material.
How we do it
We template the full stack, order the cap to fit your exact crown dimensions, and install it with no gaps for rain or animals.
What Chimney Cap & Crown Costs in Washington
| Item | Typical range in Washington |
|---|---|
| Cap installation | $180 - $480 |
| Crown repair | $350 - $900 |
| Multi-flue cap | $400 - $950 |
Do I need HPO approval for a chimney cap in Washington?
In historic districts like Georgetown, Capitol Hill, and Dupont Circle, yes, often you do. Exterior changes to a visible chimney stack can trigger Historic Preservation Office review. We handle the coordination and paperwork as part of the job. Call (240) 220-9395 to talk through your specific block.
Can I just patch my crown instead of recasting it?
Small cracks can be sealed effectively, but if the crown is spalled or pulling away from the flue, patching buys one winter at most. Washington’s freeze-thaw cycling will reopen it. We only recommend recasting when the camera and surface evidence support it, and we show you the photos. Call (240) 220-9395 for a written assessment.
Chimney Liner & Rebuild in Washington
Washington’s rowhouses were built with clay tile flues sized for coal, and most were never relined when the homes converted to gas. Today those original clay tiles are cracked, deteriorated, or completely missing in spots, and gas appliances are venting through them every day. In a shared party-wall stack, that failure lets combustion gases migrate between flues, into neighboring homes, or into basement apartments added decades after original construction. A stainless liner solves this definitively. Full details are on the Chimney Liner & Rebuild page.
Stainless Steel Liner
Signs you need it
Your gas furnace or water heater vents into an original clay tile flue built for coal, or the flue is unlined entirely.
What it costs in Washington
A stainless steel liner in Washington typically runs $1,800 to $3,200 installed, depending on flue height and diameter.
How we do it
We run a camera first to confirm flue condition, size the liner to your appliance’s BTU output, and install it with proper insulation.
Liner Replacement
Signs you need it
Your existing liner is cracked, rusted through, or was installed without insulation or the correct sizing.
What it costs in Washington
Liner replacement in Washington typically runs $1,900 to $3,500 depending on access and existing liner removal.
How we do it
We remove the failing liner, photograph what remains of the flue, and install the correctly sized replacement with a written warranty.
Partial Rebuild
Signs you need it
The top five to ten courses of brick are spalled or loose, but the flue below is structurally sound.
What it costs in Washington
Partial rebuild work in Washington typically runs $1,500 to $3,200 depending on height and brick matching needed.
How we do it
We dismantle to sound brick, rebuild with matched brick and correct mortar, and recast the crown over the new work.
What Chimney Liner & Rebuild Costs in Washington
| Item | Typical range in Washington |
|---|---|
| Stainless steel liner | $1,800 - $3,200 |
| Liner replacement | $1,900 - $3,500 |
| Partial rebuild | $1,500 - $3,200 |
How do I know if my liner has actually failed?
You cannot know from the ground. The only way is a camera scan of the flue interior, which is exactly what we do on every visit. We show you the footage. Call (240) 220-9395 to schedule a Level 2 inspection.
Do shared rowhouse stacks need separate liners for each flue?
Yes. Each flue serving an active appliance needs its own properly sized liner. In Washington’s party-wall stacks, deteriorating clay tiles allow combustion gases to cross between flues, which is why camera verification of the correct flue matters. Call (240) 220-9395 for a written scope.
Brands We Service in Washington
We install and service liners and caps from Olympia Chimney, DuraFlex, and Copperfield. Parts are stocked at our Washington metro office, so most standard cap and liner jobs do not require a return trip. See our brands for the full list.

FAQs About Chimney Cleaning in Washington
Most Washington appointments are scheduled within five business days, and we text when the technician is on the way. Historic district jobs may add a day or two for HPO coordination depending on the block. Call (240) 220-9395 to check availability in your neighborhood.
For interior work like sweeping or relining, generally no. For exterior work on a visible chimney stack in a historic district, you may need Historic Preservation Office review. We handle that coordination as part of the written scope, and we tell you up front if it applies to your address.
Yes, and we do it regularly. The key is camera-verifying which flue belongs to which appliance before any work starts, because shared stacks in Washington often have two to four flues and cross-contamination is a real risk. The photo record shows exactly what we found in your flue.
If your chimney has not been looked at in a year or more, call (240) 220-9395. We will put a camera down the flue, show you what we find, and hand you a written price before anyone touches the brick. That is how every Washington job starts.
