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.

Our Chimney Repair Services in Leesburg
We handle the full range of Chimney Repair work across Leesburg, from quick cap replacements in newer subdivisions to full rebuilds on pre-Civil War stacks. Here’s what most Leesburg calls come down to.
Mortar Repointing
Leesburg’s freeze-thaw cycles at the foot of the Blue Ridge are rough on mortar joints, especially on the multi-wythe brick chimneys in and around Old Town. Repointing means cutting out the deteriorated mortar and packing in fresh material that matches the original in color, texture, and compressive strength. A careless repoint with the wrong mortar can trap moisture and spall the brick itself. We match it right, and the joints hold for decades.
Spalling Brick Repair
Spalling is what happens when water gets into the brick face, freezes, and pops the surface off in flakes or chunks. We see it constantly on Leesburg chimneys, particularly the upper courses and crown areas of 18th- and 19th-century homes where the original brick was softer than modern fired clay. Depending on the extent, we can surgically replace individual bricks or rebuild entire sections. On historic Old Town properties, we match the brick dimension and mortar color so the repair disappears into the original work.
Chimney Waterproofing
Leesburg sits at roughly 350 feet at the eastern foot of the Blue Ridge Mountains, which means more aggressive freeze-thaw cycling than lower-elevation communities like Herndon or Sterling to the east. A water-repellent treatment, properly applied to clean, sound masonry, stops most spalling and crown cracking before it starts. We use breathable repellents that keep water out while letting the brick release moisture vapor. Sealing with paint or non-breathable coatings is worse than doing nothing, and we’ll tell you if a previous owner made that mistake.
Flashing Repair
Leaks around the roofline are usually flashing failures, and we find them all over Leesburg’s Route 7 and Route 15 growth corridors. Builder-grade flashing from the 1995-2015 buildout rusts through, lifts at the seams, or was poorly lapped in the first place. We remove the old metal, inspect the underlying masonry and roof deck, and install new flashing with proper counter-flashing and sealant integration. It’s a small repair that prevents big water damage, especially in the hard rain events that roll off the Blue Ridge.

Trusted Brands We Service in Leesburg
For factory-built fireplaces and prefab chase systems common in Leesburg’s newer subdivisions, we work with the brands that built them: Olympia Chimney for chase caps and terminations, Gelco for flashing and duct products, and Copperfield for components. If your fireplace’s manufacturer requires specific replacement parts to keep the warranty valid, we source them directly. No universal-fit hardware-store caps that void warranties and leak by spring. We stock the common parts for Leesburg’s builder-grade systems, which means most cap and flashing repairs get done in one trip.
Common Chimney Repair Problems We See in Leesburg Homes
- Rusted chase caps on 1995-2015 prefab systems. The metal flue chase on zero-clearance fireplaces rusts through at the seam where the cap meets the chase. Water gets inside, stains ceilings, and rots framing. General contractors often misdiagnose this as a roof leak. It’s a chimney cap problem, and we see it weekly along the Route 7 corridor.
- Unlined brick flues in Old Town homes. Homes built before clay tile liner requirements often have bare brick from firebox to cap. That’s uninsurable for wood-burning use and a fire hazard. The camera footage shows it plainly, and we document it for your insurer before any wood fire is lit.
- Freeze-thaw spalling at the crown and upper courses. Leesburg’s colder microclimate and elevation mean more actual wood-burning days per season than Ashburn or Reston, and the brick takes a beating each winter. Crowns crack, water enters, and the top three or four courses start popping.
- Warranty-voiding DIY repairs on prefab fireplaces. We’ve opened too many Leesburg fireplaces where someone patched a prefab chase with masonry cement or installed a cheap hardware-store cap. The manufacturer’s warranty is voided, and in tight, newer construction, a warped firebox can backdraft carbon monoxide. The camera footage and a plain-English verdict, every time, no exceptions.

FAQs - Chimney Repair in Leesburg
Yes. Your flue doesn’t care how often the fire looks nice. It cares how it breathes. Even a few fires per season build creosote, and prefab flues in tight newer construction are more sensitive to installation flaws, cap rust, and joint separation than old masonry stacks. Once a year, burn or no burn. Chimneys break in the off-season too, and a small chase cap leak can rot framing for years before you see the ceiling stain. Call (571) 518-5470 to schedule an inspection.
The most common repair is rebuilding the crown and repointing the upper courses, followed closely by Chimney Liner & Rebuild - Leesburg services for unlined brick flues. Old Town’s 18th- and 19th-century homes often have original multi-wythe brick chimneys with no clay tile liner. That’s a serious fire and insurance problem, and many owners don’t know until we put the camera up the flue. Spalling at the crown comes from Leesburg’s freeze-thaw cycles stressing original brick far more than in lower-elevation areas. Call us for an honest assessment.
Because the metal chase is hidden behind siding, and the failure point is almost always at the cap seam, which you can’t see from the ground. Builder-grade chase caps from that era rust through in 10 to 15 years, and the water runs inside the chase, down the flue, and into the ceiling. The fireplace can look perfect from the living room while the chase is quietly rotting. That’s exactly the kind of thing a quick inspection catches, and a $500 cap replacement stops a $6,000 framing repair.
Yes, and we do it routinely. We source brick that matches the original in size, color, and texture, and we match the mortar color and joint profile so the repair disappears. On a Cornwall Street NW Federal-style chimney last year, our crew replaced two dozen spalled bricks and repointed the crown, and the homeowner had to ask which bricks were new. We document everything with camera footage before and after, because you should see exactly what you paid for.
No. A round cap on a builder-grade prefab system is a manufacturer-specific part, and the replacement has to match the flue diameter and termination type. Hardware-store universal caps don’t fit properly, leak within a year, and void the manufacturer’s warranty. Worse, if the leak has already rusted the top section of the flue pipe, a cap swap won’t fix it. We’ll put the camera up, show you the exact condition, and install the right part. The camera footage and a plain-English verdict, every time, no exceptions.
