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.

Leesburg’s freeze-thaw cycles hit chimneys harder than most homeowners realize. Water seeps into hairline cracks in October, expands when January temperatures drop into the teens, and by March you’re looking at spalled brick, deteriorated mortar, or a leaning chimney stack. We’ve seen it in the older homes near downtown Leesburg, in the neighborhoods around Ida Lee Park, and throughout the newer developments near Route 15. Russell Haines founded this company on the principle that a chimney repair should last - not look good for a season and fail again. That’s why we document every inspection with photos you can see, deliver a plain-English verdict, and back every repair with our 90-Day Done Right Promise in writing. No arguing. If it’s not right, we make it right.
Our K.E.Y.S. values code governs every job: Krafted right, Every time, Your home first, Standing behind it. We’ve been in Leesburg long enough to know which mortar mixes hold up to our wet winters, which waterproofing treatments actually breathe instead of trapping moisture, and which flashing details fail first on the gable-end chimneys common in Brambleton and South Riding. We don’t chase calls with lowball estimates - we give you the number that covers the job done correctly, and that’s the number on your invoice.
What Our Chimney Repair Service Includes
Mortar Repointing
Mortar repointing is the process of grinding out deteriorated mortar between bricks and packing fresh, properly matched mortar into the joints. In Leesburg, we repoint chimneys where winter freeze-thaw has turned mortar powdery or where original lime-based mortar has eroded over decades of exposure. We analyze your existing mortar for compressive strength, sand aggregate size, and color, then mix a repair mortar that bonds without trapping moisture - a common failure when inexperienced crews use standard Portland cement on historic chimneys.

Spalling Brick Repair
Spalling occurs when water-saturated bricks freeze, expand, and flake or pop their faces off - a problem we see regularly in Leesburg’s 1980s and 1990s brick construction where softer, more porous bricks were common. We don’t just seal over spalled brick; we remove and replace damaged units with matching brick, then address the water source that caused the damage. Our crews carry common brick profiles to match Leesburg’s residential architecture, and we source from regional suppliers when needed for historic homes near the courthouse.

Chimney Waterproofing
Chimney waterproofing applies a vapor-permeable sealant to the exterior masonry that blocks liquid water while allowing trapped moisture to escape. We use professional-grade treatments from Copperfield and Olympia Chimney, never the hardware-store coatings that seal water in and accelerate deterioration. In Leesburg’s climate, with 40-plus inches of annual rainfall and humidity that stays high through October, proper waterproofing can add fifteen to twenty years to a chimney’s service life. We apply it only after repairing existing damage - waterproofing over cracked or spalled masonry is a waste of your money.

Flashing Repair
Flashing is the metalwork where your chimney penetrates the roofline, and it’s the single most common leak source we find in Leesburg homes. Our technicians inspect step flashing, counterflashing, and cricket or saddle configurations using close-up photography so you can see exactly where water is entering. We fabricate and install custom flashing from copper and galvanized steel, sealed with high-temperature sealants rated for the temperature swings of Northern Virginia. In neighborhoods like Belmont and Cascades where steep roof pitches are common, we pay particular attention to cricket construction that diverts water around the chimney rather than letting it pool.

Chimney Rebuilding
Partial or full chimney rebuilding becomes necessary when structural integrity is compromised - significant leaning, extensive spalling through multiple wythes of brick, or deterioration of the inner flue liner that can’t be addressed from the top. We rebuild chimneys in Leesburg from the roofline up or from the ground, depending on the scope, always pulling proper permits through Loudoun County and building to current code. Our rebuilds incorporate proper flue sizing, solid crown construction with adequate overhang and drip edge, and ventilation details that prevent the moisture buildup that caused the original failure.

Tuckpointing
Tuckpointing is the decorative and functional technique of removing old mortar and replacing it with new mortar colored to match the brick, often with a thin contrasting line for visual crispness. We perform tuckpointing on Leesburg’s historic homes and on newer properties where homeowners want to restore the clean, intentional look of original masonry. Our color-matching process uses mineral-based pigments that won’t fade, and we tool joints to match the original profile - concave, vee, or weatherstruck - so the repair disappears into the wall.

Brands We Service for Chimney Repair
We work exclusively with professional-grade materials from manufacturers who stand behind their products the way we stand behind our work. For chimney liners and relining components, we specify DuraFlex stainless steel liners for their corrosion resistance in the acidic flue gases of gas and oil appliances, and we’ve installed hundreds of their systems in Leesburg homes with zero material failures. Olympia Chimney supplies our premium liner systems and termination caps - their multi-flue caps with integrated dampers are our standard recommendation for Leesburg homeowners dealing with down drafts on windy sites near the Potomac or in the exposed elevations of western Loudoun County.
Famco manufactures the chimney caps, dampers, and termination hoods we use for custom installations where standard sizes won’t work, and their galvanized and stainless products hold up to our regional salt and pollution exposure. Copperfield provides specialty repair materials including professional-grade waterproofing treatments, crown repair compounds, and flue joint sealants - we apply their products according to manufacturer specifications, which is why our waterproofing warranties remain valid. Whether your chimney was built with these brands originally or any other make, we can source compatible repair materials and install them to manufacturer standards.
Signs You Need Chimney Repair Right Now
- White efflorescence or green staining on exterior brick - These deposits indicate water moving through the masonry and carrying salts to the surface. Efflorescence means water is getting in somewhere above the stain line, and the freeze-thaw cycle is actively damaging your chimney. In Leesburg, we see this most on north-facing exposures where sun doesn’t dry the masonry quickly.
- Cracked or missing mortar joints you can pick at with a key - Mortar should be harder than your fingernail. If you can gouge it, water can penetrate it, and winter will widen those gaps exponentially. We repoint chimneys every spring where homeowners noticed this the previous fall and waited.
- pieces of brick or mortar in your yard or fireplace - Spalling produces debris. If you’re finding flakes at the base of your chimney or in the firebox, the face of your brick is separating from the body. This never stops on its own; it accelerates as more surface area becomes exposed to water.
- Damp patches on interior walls or ceilings near the chimney - Water staining inside means flashing failure, crown cracks, or deteriorated mortar has allowed water past the masonry shell. By the time you see interior damage, the structure behind your walls has been wet for months. We use thermal imaging during inspection to trace the full extent.
- Your chimney crown is cracked, sloped toward the flue, or missing chunks - The crown is your chimney’s umbrella. A proper crown sheds water past the masonry edges; a failed one funnels water directly into the structure. We rebuild crowns with proper concrete mix, reinforcement, and overhang - never the thin mortar wash that cracks within two seasons.

How Much Does Chimney Repair Cost in Leesburg?
Chimney repair costs in Leesburg vary with the scope of damage, accessibility, and materials required. Here’s what we typically see in our market:
| Repair Type | Typical Range in Leesburg | What Affects Price |
|---|---|---|
| Mortar repointing (standard chimney) | $350 - $1,200 | Height, mortar type match, extent of deterioration |
| Spalled brick replacement (localized) | $500 - $1,800 | Number of bricks, matching difficulty, underlying moisture source |
| Chimney waterproofing | $400 - $950 | Surface area, prep work needed, number of coats |
| Flashing repair or replacement | $650 - $2,100 | Roof pitch, chimney size, cricket/saddle construction |
| Crown repair or rebuild | $800 - $2,400 | Size, reinforcement, accessibility |
| Partial chimney rebuild (roofline up) | $2,500 - $4,500 | Height, liner condition, permit requirements |
| Full chimney rebuild | $5,500 - $12,000+ | Height, foundation condition, flue system replacement |
Several factors push costs toward the higher end of these ranges. Chimneys over two stories require additional scaffolding and safety setup. Historic homes in downtown Leesburg may need custom brick matching or lime mortar that costs more than standard Type N. Water damage that has compromised the interior flue liner adds relining costs to the exterior repair. And chimneys with poor access - tight side yards, steep roofs, or heavy landscaping - take more time to work around safely.
The most expensive repair is the one you pay for twice. We’ve been called to Leesburg homes where a previous contractor’s “waterproofing” trapped moisture inside the masonry, or where repointing with the wrong mortar accelerated deterioration. Our upfront pricing includes the right materials and methods for your specific chimney, not a generic approach that fails in our climate.
Every estimate from Hearthstone Chimney Co. is free and carries no obligation. We don’t pressure you to decide on the spot. For repairs over $250, mention our standing offer for $50 off. Seniors and veterans receive a permanent 5% discount.

Frequently Asked Questions - Chimney Repair in Leesburg
Chimney repair fixes structural and functional damage to your chimney’s masonry, liner, crown, cap, or flashing, while a chimney sweep removes combustible creosote deposits from the flue.

Many Leesburg homeowners bundle a Level-2 inspection with their sweep, which lets us catch repair needs early.
Most standard repairs - repointing, flashing replacement, waterproofing - are completed in a single day.
