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 Alexandria
Chimney repair in Alexandria, VA most often comes down to one of three jobs: repointing soft historic brick, rebuilding a deteriorated crown, or replacing flashing that’s let water behind the stack. Before any of that, though, regular Chimney Cleaning & Sweep - Alexandria service helps catch problems early. We work across Old Town, Del Ray, Rosemont, and the West End, and our crews know what Alexandria’s housing stock actually requires. If you’ve noticed spalling brick, a leaning stack, or water staining on the ceiling near your fireplace, call (571) 443-8256 and we’ll schedule a camera-scan inspection with a written price before any work starts.
Why Level Two Chimney Fairfax Is Alexandria’s Preferred Chimney Repair Company
Alexandria homes are not like the rest of Northern Virginia. An 1840s Federal rowhouse on Prince Street and a 1990s colonial off Kingstowne need different materials, different mortar, and different repair approaches. Our techs work with the soft hand-molded brick and lime mortar common in Old Town, and we understand that a chimney stack on a shared party wall carries obligations to your neighbor, your HOA, and the Board of Architectural Review. Repointing with the wrong mortar here isn’t a cosmetic mistake. It’s structural damage within three winters.
We carry that local knowledge into every visit. When you book with us, you get a background-checked, uniformed technician, a text when they’re on the way, and a documented photo record of everything we find. Corrine Halstead, who leads our team, made camera-scan documentation the default on every job back in 2009. That means you see exactly what we see before anyone asks you to spend a dollar.
Our Chimney Repair crews serve Alexandria from the brand’s Washington, DC office, with scheduling and dispatch coordinated so we can typically reach most Alexandria neighborhoods within one to three business days for non-emergency work.
Our Chimney Repair Services in Alexandria
Mortar Repointing
Old Town’s 18th- and early 19th-century rowhouses were built with hand-molded Virginia brick laid in lime mortar, a material that flexes with the building. Modern Portland cement is harder than that brick, so when a past owner or a less careful company repointed with it, the brick face starts spalling within a few freeze-thaw cycles. We repoint with matching lime mortar, joint by joint, so the repair moves with the house instead of fighting it. In Alexandria, repointing typically runs $1,800 to $4,200 for a full stack, depending on height, access, and how much of the old mortar has to be raked out first.
Spalling Brick Repair
Spalling is what happens when water gets into the brick face and freezes, causing the surface to flake, chip, or pop off in sheets. Alexandria’s winter temperature swings, crossing 32°F dozens of times, accelerate this on any chimney that’s absorbed moisture. On an Old Town stack, we cut out the damaged brick, replace it with salvaged or matched brick where possible, and repoint with lime mortar. On newer construction in the West End, we match the original brick and reset it in compatible mortar. Spalling repair in Alexandria generally runs $1,400 to $3,000 per face, more if we’re rebuilding a corner or replacing a significant number of bricks.
Chimney Waterproofing
Alexandria sits on the Potomac, and that proximity means north-facing crowns catch moss and biological growth that holds water against the mortar. Del Ray’s 1930s and 1940s bungalows are especially prone because their crowns were poured thin and often lack a proper drip edge. We clean the crown, repair hairline cracking, and apply a siloxane-based water repellent that lets the masonry breathe while keeping bulk water out. Waterproofing on an Alexandria chimney typically runs $900 to $1,600 including crown prep. This is not a paint, and it won’t change the color of the brick.
Flashing Repair
Flashing is the metal transition where the chimney meets the roof, and in Alexandria it fails in two predictable ways: old galvanized flashing rusts through along the Potomac-facing sides, and poorly installed step flashing leaks at the corners on steep Old Town rooflines. We replace flashing with properly stepped, counter-flashed copper or powder-coated steel, and we document the seam conditions with photos before we close up. Flashing repair in Alexandria runs $850 to $1,800 depending on chimney size, roof pitch, and how much of the old flashing can be reused.

BeforeAfterTrusted Brands We Service in Alexandria
We install and service liners and components from DuraFlex, Olympia Chimney, and Famco. These are the three we turn to most often for Alexandria rowhouses because their stainless liners hold up to the constant heating and cooling cycles we see here, and because we can get their components quickly when a repair can’t wait. When your HOA or the Board of Architectural Review asks for documentation on what we’re installing, we provide specification sheets and our written scope so the approval process doesn’t stall on missing paperwork.
Common Chimney Repair Problems We See in Alexandria Homes
- Portland cement repointing on old brick. A past contractor used hard mortar on soft hand-molded brick. The face spalls within a few winters, and full face replacement becomes necessary. We see this constantly in Old Town.
- Dormant flues packed with debris. In a three- or four-flue stack serving a single active fireplace, the unused flues collect bird nests, leaves, and collapsed tile. Because the flues share a masonry party-party wall, debris in one becomes a fire hazard for all.
- Crown moss on north-facing walls. Shade and Potomac humidity keep the crown damp, moss takes root, and freeze-thaw cycles widen the cracks the moss created. By the time you see it from the street, the crown usually needs repair, not just cleaning.
- Flashing failures on shared stacks. When a rowhouse stack serves two homes, each side has its own flashing, but water entry on one side travels through the shared masonry. What looks like your neighbor’s leak becomes a repair that needs both owners, and often both HOAs, in the loop.

FAQs - Chimney Repair in Alexandria
Yes, if the cap is visible from the street or changes the exterior appearance of the structure, you’ll need BAR approval before installation. Alexandria’s Board of Architectural Review governs exterior alterations in the Old Town National Historic Landmark District, and caps, crowns, and repointing all fall under that review. We prepare the written scope and material specifications for your submittal, and coordinate scheduling around the BAR calendar so the work happens after approval, not before. Call (571) 443-8256 and we’ll walk you through the timeline.
We remove the old mortar by hand or with low-impact tools, never with an angle grinder that chips the brick face, and we repoint with a lime-based mortar matched to the original, not with Portland cement. The mortar has to be softer than the brick so it takes the movement instead of transferring it. On Old Town stacks, we also sample the existing mortar to match color and aggregate. In a full repointing job, we work a section at a time so the stack stays stable while we rake, clean, and repoint.
In most cases, yes, you can repair just your flue, but the work and the access often involve the neighboring property. Shared stacks are common in Old Town rowhouses, and when your side needs a liner or tuckpointing, the repair can disturb the party wall between flues. We inspect the full stack by camera, document the condition of all flues - yours and the shared ones - and provide a written scope that makes clear what’s on your side, what’s on your neighbor’s side, and what’s in the shared wall. We coordinate with the neighbor’s HOA or property manager and the BAR where needed. If there’s a fire hazard in a dormant flue you don’t use, our record makes that clear with photos so you’re not guessing.
North-facing crowns in Del Ray stay damp through most of the winter because of low sun exposure and Potomac humidity, and moss takes root in the pores and hairline cracks. Each freeze-thaw cycle widens those cracks, which lets more water in. The fix is a proper crown repair or rebuild with a drip edge that sheds water away from the brick, followed by a siloxane waterproofing treatment. This typically runs $1,600 to $2,900 in Alexandria. Call (571) 443-8256 for a written quote.
Yes, and any competent home inspector will flag them if they’re damaged. Alexandria’s older rowhouse stacks commonly contain multiple flues, and unused flues frequently hold bird nests, creosote, and collapsed tile that create a fire hazard for the entire stack. Before a sale, we recommend a camera inspection of every flue, active or not, so you have a documented photo record to show the buyer and their inspector. If repair is needed, we quote it in writing and coordinate with any HOA or BAR requirements so the sale isn’t delayed.
Shared Structures, HOAs, and the Old Town Reality
Most chimney repair companies work on detached houses. Alexandria, especially Old Town and parts of Del Ray, is a different world. A single stack may serve three or four flues across three floors, with some flues active and some that haven’t been used in decades. When a dormant flue fills with debris or collapses, the fire risk travels through the shared masonry wall to your neighbor’s fireplace. And because the Old Town district is a National Historic Landmark, exterior work on that stack, whether it’s repointing, a new cap, or a crown rebuild, requires Board of Architectural Review approval before a single brick is removed. That combination, shared flues plus historic review plus HOA coordination, is exactly what our Chimney Repair team was built to handle.
We worked on a Federal rowhouse near Prince and Lee Streets in Old Town where the stack held three flues. The active flue served a wood stove with no liner. The two dormant flues were packed with decades of bird nesting, and one had tile that had partially collapsed from the adjacent flue. We repointed the soft hand-molded brick with matching lime mortar, installed a DuraFlex stainless liner in the active flue, sealed the dormant flues, and coordinated with the HOA and the Board of Architectural Review to get the cap approved for the stack. The homeowner didn’t have to manage any of that paperwork.
If you’re in a shared-structure property and you’ve been told by an inspector that your chimney needs work, or you’re just trying to figure out what you’re actually looking at, call (571) 443-8256. We’ll schedule a Level 2 camera inspection, give you a written price with a written scope, and document everything with photos so you have a record to share with your HOA, your neighbor, or your real estate agent.
