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 usually costs between $250 and $2,800 depending on whether we’re repointing a few rows of brick or rebuilding a crown and relining a flue. Most mortar and flashing repairs run $350-$900, while a partial rebuild or liner installation can push into the $1,800-$4,500 range on older multi-flue stacks. We get it. You want a straight answer before anyone rings your doorbell. Call (240) 220-9395 and we’ll give you a written price before work starts. Not a ballpark. A written price, a written scope, and a written warranty, every time.
We work both halves of Leesburg: the 18th- and 19th-century masonry chimneys along King and Cornwall Streets, and the prefab fireplace chases in Lansdowne, Potomac Station, River Creek, and Stratford. A chimney repair diagnostic in Old Town is not the same job as one three miles east in a 1998 colonial. That split is the entire reason this page exists.
Why Level Two Chimney Gaithersburg Is Leesburg’s Preferred Chimney Repair Company
Since 2009, we’ve completed more than 38,000 chimney inspections and cleanings, every one documented with a camera scan and a photo record before our tech leaves the property. That’s Clause 4 of the Haven Standard, and we wrote it into our operating practice years before insurers started asking for it. In Leesburg, that matters more than most places, because an 1840s multi-flue stack hiding spalling brick at the smoke chamber and a 1996 prefab chase with a failing flashing saddle are completely different repair problems. You can’t fix what you can’t see, and we don’t ask you to take our word for it. We hand you the footage.
Corrine Halstead leads our team, and she’s the reason every job runs on evidence, not enthusiasm. Background-checked, uniformed technicians arrive on schedule with a named tech assigned and a text before we pull up. Calls go to a live person 24 hours a day. No voicemail tree. And if our work isn’t done right, the 365-Day Done Right Promise means we make it right. Stamped on every job under the Haven Standard.
We’re not the oldest name in Loudoun County, and we won’t pretend to be. We’re the company that puts a written price and a written warranty in your hand before any brick gets touched. Homeowners in Leesburg who bought between 2015 and 2025 tend to research first and call second. We respect that. That’s why the price is on this page.
Our Chimney Repair Services in Leesburg
We focus on the storm-driven failures Leesburg actually sees: wind and rain driving into cracked crowns, flashing that lets water run down a chase, brick that’s been spalling for years under the Piedmont freeze-thaw cycle. Here’s what we do most often.
Mortar Repointing
Leesburg sits in a cold-air drainage zone at the edge of the Blue Ridge foothills. Dulles Airport, a few miles east, routinely records the coldest overnight temperatures in the metro. That means masonry chimneys in Leesburg absorb more freeze-thaw cycles per winter than chimneys just a dozen miles closer to DC. Old Virginia lime mortar is porous by design; add decades of moisture penetration and you get crumbling joints. We repoint with a compatible lime-based mortar, never a hard Portland mix that traps moisture and blows out the face of the brick. Typical repointing on a single-family chimney in Leesburg runs $400-$1,100 depending on access and condition.
Chimney Waterproofing
Wind-driven rain in Leesburg doesn’t just run down the outside of the brick. It soaks in. On an unlined Old Town stack, that moisture migrates through the wythe and shows up as damp plaster on the interior wall, sometimes two floors down. We apply a vapor-permeable waterproofing membrane after repointing and crown work, so water beads and rolls off while the brick still breathes. Plan on $300-$700 for a standard residential chimney in Leesburg.
Flashing Repair
Where a prefab Chase-style chimney meets the roofline on a 1990s Lansdowne or Potomac Station home, the flashing is the weak point. High wind works the metal loose, sealant cracks, and water follows the chase down to your ceiling. We see the resulting brown stain more than we want to. Flashing repair or replacement in Leesburg typically runs $350-$950 depending on whether we’re resealing or cutting in new step flashing. We don’t caulk over rusted metal and call it done. If it’s compromised, we replace it.
Spalling Brick Repair
Spalling is brick shedding its face because trapped moisture expands and contracts. It’s the most common cosmetic failure we find in Old Town Leesburg chimneys, and it’s never just cosmetic. Once the face is gone, the softer core erodes fast. On Federal-period homes along Cornwall and King Streets, we cut out compromised brick and rebuild with matched historic-size units and lime mortar, not modern oversized brick and gray Type S. Spalling repair in Leesburg runs $500-$1,800 depending on the number of units and chimney height.
Chimney Rebuilding
When a crown has failed, the cap is displaced, and the top three to five courses are mush, repointing won’t hold. We rebuild from a stable point down, set a new poured crown with a proper drip edge, and install a multi-flue cap. On an Old Town stack serving three flues with no individual liners, this is the time to address liner separation. Full or partial chimney rebuilds in Leesburg run $2,000-$6,000. It sounds steep, and it’s cheaper than a chimney fire or a carbon monoxide event in the parlor.

BeforeAfterHow We Diagnose Before We Quote in Leesburg
Every repair in Leesburg starts with an NFPA 211 Level 2 camera inspection. Not a flashlight up the flue. A camera. We’re looking for Class III creosote, cracked flue tiles, liner separation, spalling at the smoke chamber, crown fractures, and water tracks from a failed cap. You get the photo record. If we’re recommending a rebuild or a liner, we’re showing you the frame that justifies it. No liner replacement gets recommended without footage showing why. No flashing work gets sold on a hunch. This is the practice that became Clause 4 of the Haven Standard in 2009, and it’s been running continuously for 38,000-plus inspections since.
We also bring a Free Second Opinion on any written estimate. If another company quoted you a rebuild, bring us the paperwork. We’ll put our own eyes on it and tell you what’s actually required under NFPA 211 and what can safely wait. In Leesburg, where Old Town chimneys often get quoted for full rebuilds that a repoint and crown would solve, that second opinion saves real money.
Common Chimney Repair Problems We See in Leesburg Homes
- Wind-driven water through cracked crowns. Leesburg storms drive rain horizontally. A hairline crown crack becomes a water channel. On an unlined 18th-century stack, that water migrates into interior plaster and lathe. We see it on Cornwall Street regularly.
- Flashing failures on 1990s prefab chases. Lansdowne, Potomac Station, and River Creek homes were built fast in the 1990s and early 2000s. The flashing saddle where the chase meets the roofline fails, moisture runs down, and the first sign is often a ceiling stain two floors down.
- Displaced caps after severe storms. A multi-flue cap that gets knocked off an Old Town chimney lets rain pour directly into three separate flues at once, soaking the shared masonry mass and accelerating spalling on already-fragile lime mortar. This is the single most common post-storm failure we respond to in Leesburg.
- 20-30 year old prefab fireplaces at end of life. The zero-clearance units installed throughout east Leesburg from roughly 1995 to 2005 are now reaching manufacturer end-of-life. Homeowners treat them as maintenance-free. They aren’t. A chase panel inspection and liner assessment tells you whether your unit is safe to burn another season.
There’s a specific reason this list matters in Leesburg more than in, say, Ashburn. Old Town is one of Virginia’s oldest intact town cores, established in 1758. The masonry chimneys along King Street were built before metal liners existed. They often serve two or three flues in a single stack with no individual liner separating them. That configuration creates cross-draft and carbon monoxide migration risks that fail current NFPA 211 standards. Meanwhile, three miles east, the suburban subdivisions are full of factory-built fireplaces that were never designed to last 30 years and are now all aging out at the same time. A chimney cleaning visit in Leesburg gets diagnosed completely differently depending on which side of town you’re on. That’s not something a generic chimney company notices. We notice because we’re crawling the flues with cameras every week.

FAQs - Chimney Repair in Leesburg
Homes built in the 18th and 19th centuries in Leesburg were constructed before stainless steel liners existed, so a single exterior chimney stack often serves two or three separate flues (parlor, kitchen, upstairs bedroom) with only the original masonry separating them. That means cross-draft between flues, carbon monoxide migration risk, and no individual liner to repair or replace. When we repair these stacks, we often recommend parging the flue interior and installing a multi-flue cap with a Gelco system to isolate each flue path. Call (240) 220-9395 for an inspection; we’ll show you the camera footage before we recommend anything.
The most likely cause is flashing failure where the prefab Chase-style chimney meets the roofline. High wind loosens the flashing saddle, sealant cracks, and rainwater runs down the chase and pools at the ceiling level. In a 1990s Lansdowne or Potomac Station home, this is the single most common post-storm chimney failure we see. We’ll inspect the flashing, reseal or replace as needed, and camera-check the chase interior to confirm water hasn’t compromised the firebox. Estimates are free.
Yes. The original mortar in Old Town Leesburg chimneys is Virginia lime mortar, which is soft, porous, and breathable. Repointing with a hard Portland cement mortar traps moisture in the brick and accelerates spalling. We use a compatible lime-based mortar matched in color and texture to the existing joints. A typical repointing job in Leesburg runs $400-$1,100, and it’s the single most effective repair for stopping water intrusion into an unlined historic stack.
Once a year, even if you only burn occasionally. Leesburg sits in the coldest part of the Northern Virginia metro due to cold-air drainage off the Blue Ridge foothills, which means the fires you do burn run hotter and hotter fires produce heavier creosote accumulation than a once-a-year cleaning schedule assumes. Add wind-driven rain exposure to an aging crown or cap, and an annual Level 2 inspection is the minimum for safety. If it’s been more than a year, call (240) 220-9395.
Check the cap first: is it still seated properly or has wind displaced it? Then look at the crown for cracks, and scan the interior ceiling around the chimney for any new staining. If you see displaced caps, cracked crowns, or water tracks, don’t light a fire until a pro has camera-inspected the flue. Wind-driven rain that poured directly down an open flue accelerates spalling and creosote bonding. In Leesburg, where storms move off the Blue Ridge with real force, a post-storm inspection before the first burn is the single smartest thing you can do. Call (240) 220-9395 and we’ll get a Level 2 camera inspection scheduled on the next available visit.
