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 Repair Across Washington
Chimney repair in Washington, DC typically runs $450-$2,800 depending on what’s failing, and the most common culprits on DC row houses are corroded flashing, spalled brick from freeze-thaw cycling, and cracked flue liners hiding behind shared wythe walls. We work across every ward, from Georgetown’s Federal-era stacks to Petworth’s three-flue Victorian chimneys, and we show you camera footage of exactly what we find before quoting a written price. Call (240) 290-6726 and we’ll send a background-checked, uniformed technician who arrives with a scope, not a flashlight.
Why Level Two Chimney Alexandria Is Washington’s Preferred Chimney Repair Company
Since 2009, our crews have inspected and repaired more than 38,000 chimneys, and a good share of those sit on the tight brick rows of Capitol Hill, Shaw, and Bloomingdale. Washington homeowners deal with a very specific problem: original multi-flue stacks built for coal and wood in the 1890s through the 1920s, now venting gas furnaces and water heaters through flues that were never sized or lined for modern exhaust. We know these stacks. We know what fails first, we know what Historic Preservation Review Board rules apply in Georgetown, and we know which cracks matter and which ones can wait.
Every visit includes a camera-scan inspection under NFPA 211 Level 2, a documented photo record you keep, and a written price before any work starts. That’s Clause 4 and Clause 1 of the Haven Standard, and we’ve operated that way from day one. No tech ever starts a repair without handing you a written scope and written warranty first.
Our Chimney Repair team coordinates dispatch and scheduling from our Washington, DC office, so we’re not a franchise sending someone from three counties away. When you call, a live person answers, 24/7, and you get a named tech with a text when they’re on the way. That’s H.A.V.E.N. ‘Arrive on schedule’ and ‘Verified crews’ in practice.
Our Chimney Repair Services in Washington
Flashing Repair
Corroded flashing is the single most common repair we make on Washington row houses, and it fails faster here than almost anywhere else in the Mid-Atlantic. The Potomac basin humidity keeps the masonry damp year-round, and the thin galvanized flashing used on many 1920s rowhomes simply gives out after 30 or 40 winters. On Capitol Hill we regularly replace step flashing and counter-flashing with copper or heavy-gauge stainless, re-sealing the roof-to-chimney joint so water stops running down the brick face. Flashing repair in Washington runs $450-$1,200 for a standard single-flue stack, more if the cricket needs rebuilding.
Mortar Repointing
Washington’s humid subtropical climate is uniquely hard on mortar joints. Warm wet air off the Potomac keeps brick saturated into the winter, then freezes, expanding inside the joint and eroding the mortar from within. In Petworth and Columbia Heights we see crown and shoulder repointing needed on chimneys that inland cities wouldn’t touch for another decade. A typical repointing job on a DC row house runs $1,200-$2,600 depending on stack height and access. We use lime-based mortar matched to your original joints, because Portland cement on century-old soft brick causes spalling, not fixes.
Spalling Brick Repair
Loose bricks falling from multi-flue stacks are a weekly sight on Petworth and Columbia Heights row houses. Spalling happens when water penetrates the brick face, freezes, and pops the surface off. Left alone, a spalled chimney loses structural integrity and becomes a falling-brick hazard onto your roof or your neighbor’s. We replace spalled brick with salvage-matched or new brick of matching compressive strength, then waterproof the stack with Gelco to slow future moisture intrusion. Spalling repair in Washington typically runs $800-$2,000 when the damage is caught before it reaches structural depth.
Chimney Rebuilding
When freeze-thaw damage has gone too deep, when the stack is leaning, or when multiple flues have cracked liners, rebuilding is the honest answer, and we’ll tell you that plainly. A full chimney rebuild in Washington runs $4,000-$12,000 depending on stack height, flue count, and whether you’re in a Historic District with material restrictions. We rebuild with modern brick, proper crown overhang, and new stainless liners where the flues have failed. Every rebuild gets the same written warranty and the 365-Day Done Right Promise: if it’s not done right, we make it right.

BeforeAfterCommon Chimney Repair Problems We See in Washington Homes
- Corroded flashing at the roof line. Decades of damp Potomac air and freeze-thaw cycles eat through thin galvanized flashing on 1920s-era row houses. You’ll see it as water stains on the ceiling near the chimney, but the leak starts at the shingle joint.
- Spalled brick and eroded mortar on the stack. The DC humidity cycle is worse than Philadelphia or Baltimore for brick decay, because the Potomac basin keeps masonry damp going into every freeze. Loose brick faces and crumbling joints follow quickly.
- Hidden flue cracks in multi-flue stacks. Original unlined or terra-cotta flues from the 1890s-1920s, now venting gas furnaces and water heaters, crack under modern exhaust temperatures. The crack leaks carbon monoxide into wall cavities and adjacent flues, invisible from the street and undetectable without a camera.
- Historic district compliance issues. In Georgetown, older Federal-period chimneys may be unlined rubble masonry, and the DC Historic Preservation Review Board restricts what liners and caps can be installed without approval. We handle the paperwork and know which materials pass review.

Trusted Brands We Service in Washington
We install and service liners and components from HeatShield, Gelco, Olympia Chimney, and Famco, and we keep a local parts inventory at our Washington, DC office so most repairs don’t wait on shipping. A cracked terra-cotta liner in a Capitol Hill row house gets a DuraFlex stainless replacement or a HeatShield resurfacing system, matched to the flue’s original dimensions. We use Gelco waterproofing on brick stacks because it breathes, which matters in DC’s humid climate where sealed moisture rots brick from the inside. You get the manufacturer’s warranty plus our 365-Day Done Right Promise on top.

FAQs - Chimney Repair in Washington
Georgetown’s Historic Preservation Review Board requires approval for visible exterior changes like liner caps, crown materials, and brick color, and many Federal-period homes predate 1820 with unlined rubble masonry stacks. We prepare the application, document the existing condition with photos, and specify materials that pass review; the process typically adds two to six weeks before work starts.
Because the Potomac basin holds humidity against the brick through the winter, and every freeze cycle works on damp masonry. Petworth’s late-Victorian stacks sit fully exposed on three-story open rows where wind drives moisture into the face, making the freeze-thaw erosion measurably worse than in the drier inland counties. Call (240) 290-6726 if you’re seeing brick flakes on your roof or sidewalk; catching spalling early is the cheapest fix.
If the mortar joints are eroded but the bricks themselves are intact, tuckpointing ($600-$1,500 localized) usually restores integrity. If bricks are spalling, the stack leans, or a camera inspection shows cracked flues in multiple columns, you’re looking at a partial or full rebuild. We scope every flue and hand you the footage before recommending anything. No repair gets recommended without evidence you can see.
Every year, before burning season, which in DC means September or October, schedule Chimney Cleaning & Sweep in Washington. Row house stacks often carry three or four flues sharing thin brick wythes, and a crack in one column can back-draft combustion gases into an adjacent active flue. Annual Level 2 inspection with camera scoping is the only reliable way to catch that before it becomes a CO problem. The 38,000 plus inspections we’ve done since 2009 have turned up exactly this failure pattern more times than I can count.
Usually yes. We replace the step and counter-flashing at the chimney base, leaving the rest of your roof untouched, and we do it in copper or heavy-gauge stainless so you don’t repeat the repair in ten years. Typical job runs $450-$1,200 and we include a written warranty on the flashing work, not just the materials.
