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 Leesburg
Chimney repair in Leesburg, VA typically costs $350-$1,400 for mortar repointing, $1,800-$3,200 for flue liner installation, and $450-$900 for chimney waterproofing, with most jobs completed in one visit. We work on both sides of Leesburg’s housing divide: the 18th-century brick colonials in the historic district and the 1990s prefab fireplaces throughout Lansdowne and River Creek. If you’re seeing spalling brick, water stains near the firebox, or a gas insert venting into a flue that predates your great-grandparents, call (240) 220-9412 and we’ll put a camera down the flue before we quote anything.
Why Level Two Chimney Ashburn Is Leesburg’s Preferred Chimney Repair Company
Our Chimney Repair team works in Leesburg every week, and the calls we get tend to split cleanly: historic masonry failing from freeze-thaw cycles on the west side of town, and prefab units showing their age in the eastern subdivisions. We’ve inspected over 38,000 chimneys since 2009, and every one of those jobs began with a written price before any work started. That’s Clause 1 of the Haven Standard, and we don’t make exceptions.
Leesburg homeowners get something most chimney companies don’t offer: a camera-scan inspection with a documented photo record on every visit, not just when you’re already worried something’s wrong. Clause 4 of the Haven Standard has required this since 2009, long before insurers started asking for it. When Corrine Halstead founded Level Two, she made the Level 2 camera inspection the default, and that practice became the spine of our entire operation.
We’re not the cheapest shop in Loudoun County, and we’re not trying to be. We’re the shop that shows you the cracked flue tile on a screen before quoting the repair, hands you a written scope with the price on it, and backs it with the 365-Day Done Right Promise. If it’s not done right, we make it right.
Our Chimney Repair Services in Leesburg
Mortar Repointing
Mortar repointing in Leesburg runs $350-$1,400 depending on chimney height, joint depth, and access. The historic brick homes around King Street and Cornwall Street were built with lime-based mortar, which is softer than modern Portland cement and moves with the brick through Leesburg’s freeze-thaw cycles. When someone repoints those joints with hard modern mortar, it traps moisture behind the brick and accelerates spalling. We match the original mortar composition, which matters more on a 1780s colonial than it does on a 2004 colonial in River Creek.
Spalling Brick Repair
Spalling brick repair in Leesburg typically costs $800-$2,400, depending on how many bricks need replacement and whether the damage is cosmetic or structural. We see spalling most often on west-facing chimneys on elevated lots near the Catoctin foothills, where prevailing northwest winds drive rain into the brick and the freeze-thaw cycle does the rest. A brick face that’s popped off is letting water into the chimney system. Left alone, it’s not just ugly: the chimney core starts degrading and the repair bill climbs.
Chimney Waterproofing
Chimney waterproofing in Leesburg runs $450-$900 for a standard one- or two-flue chimney. This is the single best preventive repair for historic brick chimneys in town. We use vapor-permeable water repellents that let moisture escape while keeping rain out, applied after the masonry is cleaned and any failed mortar joints are cut out and replaced. For a brick chimney in Leesburg’s historic district that’s absorbed two centuries of Piedmont weather, waterproofing done right buys years between repointing cycles.
Flashing Repair
Flashing repair in Leesburg runs $400-$1,100 when caught early, and more if water has already rotted decking or framing beneath. The old-town homes with their steep slate roofs and complex rooflines create flashing geometry that suburban roofers often get wrong. We cut out failed flashing, inspect the underlying roof deck, and install new step and counter flashing that actually sheds water rather than channeling it into the chimney chase. Most leaks we find in Leesburg attics trace back to flashing failures, not the brick itself.

BeforeAfterTrusted Brands We Service in Leesburg
We work on factory-built fireplaces from every major manufacturer, and we keep parts on the truck for the common failures in Leesburg’s 1990s and 2000s subdivisions. That means less waiting when a refractory panel cracks in a Lansdowne family room or a gasket fails in a River Creek firebox. We source materials from DuraFlex, Famco, and Copperfield through Haven’s buying network specifically to keep parts pricing honest for Leesburg customers. If you’ve got a unit with a manufacturer’s label still readable, we’ll match the right component to it. If the label’s gone, the camera inspection tells us what we’re working with.
Common Chimney Repair Problems We See in Leesburg Homes
- Gas inserts venting into unlined antique flues. In Leesburg’s historic district, it’s common to find brick flues that were opened up for gas inserts in the 1980s with no stainless liner installed. Gas exhaust is cooler and wetter than wood smoke, so it condenses inside the oversized brick flue and breaks down the masonry from the inside. This is a routine find here that would be unusual almost anywhere else in the DC metro.
- Failed mortar joints from freeze-thaw cycling. Leesburg sits at the Piedmont’s edge near the Catoctin Mountain foothills, with colder winters and more snow than Fairfax County. Water gets into hairline cracks in the mortar, freezes, expands, and pries joints open. A decade of that turns 1/8-inch cracks into missing mortar beds and loose bricks.
- Cracked refractory panels in 1990s prefabs. The subdivisions built from roughly 1993-2008 around Lansdowne and River Creek are now hitting the 20-25-year mark where UL-listed refractory panels, gaskets, and steel fireboxes commonly fail. A hairline crack in a refractory panel is not cosmetic; it changes how heat moves through the firebox and can expose the sheet metal behind it.
- Downdraft problems on elevated west-facing lots. Prevailing northwest winds channeled through gaps in the Blue Ridge create downdraft conditions in west-facing chimneys on higher ground. A chimney that backdrafts smoke into the living room on a windy Leesburg evening usually needs a draft correction, not a bigger fireplace.
Pricing for Chimney Repair in Leesburg, VA
Here’s what Leesburg homeowners should expect to pay for common chimney repairs in 2026. Flue liner installation runs $1,800-$3,200 for a typical one- or two-story home, which includes the stainless liner, top plate, crown seal, and the camera verification passthrough when we’re done. Mortar repointing on a standard single-flue chimney runs $350-$1,400. Chimney waterproofing runs $450-$900. Flashing repair runs $400-$1,100. Spalling brick replacement runs $800-$2,400. Full chimney rebuilding in Leesburg’s historic district starts around $4,500 and goes up from there, because matching 18th-century brick dimensions and lime mortar is more involved than a standard rebuild.

FAQs - Chimney Repair in Leesburg
Leesburg doesn’t have a town-specific inspection ordinance, but the National Fire Protection Association (NFPA 211) recommends an annual inspection for any chimney in active use, and many homeowners insurance policies in Virginia now ask for documented inspection records before covering chimney-related claims. What Leesburg does have is aging housing stock: a chimney that hasn’t been used in five years can still be failing from water intrusion, freeze-thaw damage, or the slow degradation of an unlined flue. A camera inspection catches those problems before they become hazards. Call (240) 220-9412 to schedule one; the photo record is included on every visit.
No, it’s not code-compliant, and it’s one of the most common findings we document in Leesburg’s historic district. Gas appliances produce acidic exhaust that condenses inside oversized brick flues and eats the mortar from the inside out. The fix is a stainless steel liner sized correctly for the appliance, typically $1,800-$3,200 in Leesburg. We recently repaired a chimney on Loudoun Street SW where a 1980s gas insert was venting directly into an unlined 18th-century brick flue. Our camera inspection showed spalling brick and missing mortar joints, so we installed a DuraFlex stainless steel liner, re-pointed the interior flue, and sealed the smoke chamber with HeatShield before replacing the damper. The homeowner watched the entire process on our camera feed and signed off only after seeing the liner fully secured and the flue clean. Call (240) 220-9412 for a written quote.
A chimney crown that keeps cracking is usually failing because water is getting behind it, not because the concrete was mixed wrong. In Leesburg’s freeze-thaw climate, a crown with no drip edge or proper slope lets water pool against the flue tile and work its way into the crown’s underside. The fix is a properly formed overhanging crown with an expansion joint around the flue, then a masonry water repellent. Crown repair in Leesburg runs $500-$1,200 depending on chimney size and whether the flue tile needs resetting. Call (240) 220-9412 and we’ll show you what’s actually failing before quoting the repair.
Look for hairline cracks in the refractory panels on the side and back walls of the firebox, a gasket that’s peeling away from the door frame, or any rust or discoloration on the metal panels above the firebox opening. Any one of those means the firebox may no longer be containing heat the way it was designed to. Prefab units in Lansdowne and River Creek are now hitting the 20-25-year threshold where these components commonly fail. A camera inspection will document it. Call (240) 220-9412 and we’ll walk you through what we’re looking at.
Waterproofing alone won’t reverse spalling that’s already happened, but it will dramatically slow future damage. Spalling happens when water inside the brick freezes and pops the face off. A vapor-permeable water repellent keeps rain out while letting moisture escape, which stops the freeze-thaw cycle from doing further damage. For a historic Leesburg brick chimney, waterproofing runs $450-$900 and is best done after any failed mortar joints are repointed. Call (240) 220-9412 for a written estimate.
