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.

A our Chimney Liner & Rebuild in Leesburg typically costs between $2,800 and $8,500 depending on whether you’re replacing a damaged liner or rebuilding masonry, and most projects are completed in one to two days. Hearthstone Chimney Co. has served Loudoun County homeowners for over 42 years, and we back every liner and rebuild job with our 90-Day Done Right Promise in writing. Call (571) 701-7519 - a live person answers 24 hours a day, 7 days a week.
We’ve worked on chimneys across Leesburg’s older neighborhoods near the historic district, in newer developments around Lansdowne, and throughout the rolling acreage west of town toward our Chimney Liner & Rebuild in Purcellville. The clay flue liners in homes built before 1990 were never designed to handle today’s efficient gas appliances, and the freeze-thaw cycles in northern Virginia winters will eventually crack mortar joints in brick chimneys that haven’t been maintained. When a liner fails or masonry deteriorates, you’re looking at carbon monoxide risk, creosote buildup in wall cavities, or structural collapse. We document every condition with a Level-2 camera inspection, show you the photos, and give you a plain-English verdict on what needs to happen now, what can wait, and what it will cost before we start any work.
What Our Chimney Liner & Rebuild Service Includes
Stainless Steel Liner
A stainless steel liner is a continuous metal flue pipe we install inside your existing chimney structure to create a safe, properly-sized passage for exhaust gases. In Leesburg, we most often install these in homes where the original clay tile liner has cracked or where a wood-burning fireplace has been converted to gas - the new appliance needs a smaller flue, and an unlined or oversized flue lets exhaust cool too quickly, causing condensation and creosote problems. Hearthstone Chimney Co. uses DuraFlex and Olympia Chimney stainless steel liners, sized precisely to your appliance’s BTU output and venting requirements, with proper insulation packs where the chimney runs through unconditioned attic or exterior wall space.
Flexible Liner
Flexible liners are corrugated stainless steel tubes that can navigate offsets and bends in chimney structures where a rigid pipe won’t fit. We’ve installed hundreds of these in Leesburg’s historic homes near Morven Park and in the farmhouses along Route 15, where chimneys often have sloped shoulders or angled flues from decades of settling. Our technicians measure the full flue path with a video camera first, then select the correct diameter and length of DuraFlex flexible liner, pulling it through from top to bottom and securing it with a top plate and proper storm collar.
Liner Replacement
Liner replacement becomes necessary when the existing flue liner - whether clay tile, old stainless steel, or poured refractory - has deteriorated beyond repair. In Leesburg, we see this most often after chimney fires have cracked tile, or when acidic condensate from high-efficiency furnaces has eaten through older metal liners installed in the 1990s. We remove the damaged liner completely, inspect the surrounding masonry for hidden damage, and install a new Olympia Chimney or DuraFlex liner system with proper connectors, insulation, and termination fittings, all documented with before-and-after photos you’ll receive in your report.
Partial Rebuild
A partial rebuild addresses specific sections of chimney masonry that have failed while the majority of the structure remains sound. The freeze-thaw cycles in Leesburg’s climate - hard freezes in January and February, followed by rapid warming - pop mortar joints and spall brick faces, especially on chimneys above the roofline where they’re fully exposed. We rebuild from the roofline up, matching existing brick where possible, installing proper through-wall flashing, and capping with a poured concrete crown sloped to shed water. Most partial rebuilds are completed in a single visit with our masonry crew.
Full Chimney Rebuild
A full chimney rebuild is required when the structure has deteriorated throughout - leaning, major cracking, or extensive water damage that has compromised the wythes (the inner and outer layers of brick). This is more common in Leesburg’s rural properties with older chimneys that lacked proper crowns or flashing from the start. We dismantle the chimney to the roofline or below, salvage usable brick if the homeowner prefers, and rebuild to current Virginia building code with proper flue sizing, a reinforced concrete crown, cricket flashing on the uphill side, and a new liner system sized for your appliances. Russell Haines oversees these projects personally to ensure the finished chimney will outlast the next generation.
Liner Repair
Liner repair is appropriate when the damage is localized - a single cracked tile at the top, a gap in a mortar joint, or minor corrosion in a metal liner - and the overall system remains structurally sound. We use HeatShield cerfractory sealant for certain clay tile repairs, creating a smooth, joint-free surface that meets NFPA 211 standards, or we can install a stainless steel sleeve to bridge damaged sections of metal liner. Every repair starts with a camera inspection so we can show you exactly where the problem is and why repair rather than replacement is the right call.

Brands We Service for Chimney Liner & Rebuild
We’ve installed and serviced hundreds of Olympia Chimney liner systems across Loudoun County, from their standard 316Ti stainless steel models to heavy-duty 904 alloy liners for coal and oil appliances. We stock common Olympia components - top plates, storm collars, and flex connectors - so we’re not waiting on shipping when your chimney needs attention. DuraFlex flexible liners are our go-to for offset chimneys in Leesburg’s older homes; we’ve pulled their corrugated stainless through flues with multiple bends and know exactly how much insulation pack to specify for your chimney’s exposure.
Famco chimney caps and termination fittings integrate cleanly with our liner installations, and we’ve used Copperfield specialty components for custom rebuilds where standard catalog parts won’t work. Whether your existing system is Olympia, DuraFlex, HeatShield, Gelco, Famco, or Copperfield - or if you have no idea what brand is in your chimney right now - we can inspect it, identify it, and fix it correctly. Our trucks carry the professional-grade materials we trust, not whatever was cheapest at the supply house that morning.
Signs You Need Chimney Liner & Rebuild Right Now
- White staining or efflorescence on exterior brick means water is moving through the masonry, dissolving salts, and depositing them on the surface. In Leesburg, this shows up most visibly on north-facing chimney exposures after wet winters. The water that’s causing that staining is also degrading your mortar from the inside out, and if it’s reached the flue liner, freeze-thaw expansion will accelerate the damage through every cold snap.
- Flakes of tile or pieces of masonry in the firebox or cleanout indicate that your clay flue liner is spalling or that mortar joints between bricks have failed. These pieces have fallen from somewhere, and that somewhere is the barrier between 2,000-degree flue gases and the wooden structure of your home. We find this regularly in Leesburg homes built during the 1960s and 1970s construction boom, where rapid building left chimneys with substandard mortar mixes.
- Smoke or odors entering living spaces when the fireplace or furnace is running means exhaust is not contained in the flue. This can be a cracked liner, a disconnected section, or a liner that was never properly sized for the appliance now venting through it. Carbon monoxide is odorless and invisible; if you’re smelling smoke, the same pathway exists for gases you can’t detect.
- Visible cracks in the chimney crown or missing chunks of mortar let water straight into the chimney structure. The crown is supposed to be a poured concrete cap that sheds water away from the flue opening and onto the roof. When it cracks - and Leesburg’s temperature swings from single digits to 50 degrees in a winter week guarantee it will - water enters, freezes, expands, and turns small cracks into structural failures within a few seasons.
- Rust stains on the chimney face or metal components mean water is getting in and staying in contact with metal long enough to oxidize it. We see this on galvanized chase covers in Leesburg’s townhome communities and on exposed damper frames in older homes. Rust never sleeps, and the metal it’s consuming is part of your chimney’s structural or functional system - liners, dampers, flashing, or firebox components.

- 1
Schedule your inspection. Call (571) 701-7519 any time - day, night, weekend, holiday - and a live person will answer. We’ll find a time that works for your schedule, not ours. Most Leesburg homeowners choose morning appointments so they’re present for the technician’s arrival and can review findings together.
- 2
Level-2 camera inspection and documentation. Our technician arrives in a marked vehicle, in uniform, background-checked and identified. We run a high-resolution video camera the full length of your flue, recording every crack, gap, and creosote deposit. You’ll see exactly what we see, in real time, on a screen we bring into your home. No hidden damage, no guessed-at conditions.
- 3
Plain-English verdict and upfront pricing. Russell Haines or a senior technician reviews the footage with you, explains what the problem is, what caused it, and what your options are - repair, reline, partial rebuild, or full rebuild. We provide a written estimate with line-item pricing before any work begins. The number on that estimate is the number on your invoice.
- 4
Professional installation with documented materials. Our crew arrives with the specified DuraFlex, Olympia Chimney, HeatShield, or other professional-grade materials, installs to manufacturer specifications and Virginia building code, and photographs the completed work. For rebuilds, we match existing brick and mortar color as closely as possible, and we never leave a chimney without proper crown, cap, and flashing protection.
- 5
Final inspection, photo report, and written guarantee. We run the camera again to verify the new liner or rebuilt structure is clean, properly connected, and functioning. You receive a photo report documenting before, during, and after conditions, plus our 90-Day Done Right Promise in writing. If anything isn’t right, we make it right - no paperwork, no arguing.
How Much Does Chimney Liner & Rebuild Cost in Leesburg?
A typical stainless steel liner installation in Leesburg runs $2,800-$4,500 for a standard fireplace or furnace flue, with the variation depending on flue diameter, chimney height, and whether insulation is required for exterior or unconditioned chimney runs. Learn more about how much Chimney Liner & Rebuild costs. Flexible liner installations in offset chimneys typically fall in the $3,200-$5,000 range because of the additional labor to navigate bends and the specialized connectors needed. Liner replacement where we must remove an existing damaged liner first adds $400-$800 for extraction and disposal.
Partial rebuilds from the roofline up in Leesburg generally cost $3,500-$6,500 depending on chimney size, brick matching requirements, and whether the crown and flashing systems also need replacement. Full chimney rebuilds are the most variable, ranging from $6,500 to $12,000+ for multi-flue structures or chimneys that must be rebuilt from below the roofline with significant structural integration into the home.
What affects your specific price: chimney height and accessibility (steep roofs or limited yard access add labor), the number of appliances being vented (each requires proper connector and sizing), whether the chimney is interior or exterior (exterior chimneys in Leesburg need insulated liners to prevent condensation), and the condition of existing masonry that must be addressed before a liner can be safely installed. We also factor in proper permitting through Loudoun County when required for structural rebuilds.
How to avoid overpaying: get a second opinion on any estimate over $3,000 - Hearthstone Chimney Co. provides free second opinions on any written estimate from another company. Be wary of anyone who quotes a liner installation without a camera inspection; you cannot price what you cannot see. And never accept a verbal-only guarantee - our 90-Day Done Right Promise is in writing before we start.
What’s included in our free estimate: the Level-2 camera inspection, a written report with photos, line-item pricing for recommended work, and a clear statement of what can wait and what cannot. Call (571) 701-7519 for your estimate - there’s no obligation and no pressure.

Frequently Asked Questions - Chimney Liner & Rebuild in Leesburg
Chimney liner and rebuild work restores the safe passage for exhaust gases from your fireplace, stove, or furnace to the outside air. A liner is the protective sleeve inside your chimney that contains heat and combustion byproducts; a rebuild addresses the brick, block, or stone structure that surrounds and supports it. Hearthstone Chimney Co. handles both, starting with a camera inspection to determine whether your situation needs relining, repair, or structural reconstruction.
Most stainless steel or flexible liner installations are completed in one day; partial rebuilds typically take one to two days; full rebuilds require two to four days depending on weather and masonry curing requirements. We schedule the work to minimize disruption, and our technicians arrive with the materials already on the truck so we’re not waiting for deliveries. Call (571) 701-7519 to discuss timing for your specific project.
Stainless steel liner installations typically run $2,800-$4,500, flexible liners $3,200-$5,000, partial rebuilds $3,500-$6,500, and full rebuilds $6,500-$12,000 or more depending on scope.

Yes - we install, repair, and replace Olympia Chimney, DuraFlex, HeatShield, Gelco, Famco, and Copperfield systems, and we stock common components for each. Even if your existing liner is an older brand or unmarked, we can identify it during inspection and source compatible replacement parts or a complete new system as needed. Our trucks carry professional-grade materials, not generic substitutes.
A failed or damaged liner can create immediate carbon monoxide exposure risk or structural fire hazard, and we treat those situations with appropriate urgency. However, most liner deterioration is gradual, and the right response is a prompt inspection to determine whether the chimney must be taken out of service immediately or can be scheduled for repair within days or weeks. We’ll give you a straight answer on urgency after we see the condition - never a scare tactic to force a same-day sale.
Every job is covered by our 90-Day Done Right Promise - in writing, with no arguing. If anything about the installation or rebuild is not right, we return and make it right at no additional cost. This is governed by our K.E.Y.S. values: Krafted right, Every time, Your home first, Standing behind it. For manufacturer-specific liner warranties, we register your installation with Olympia Chimney or DuraFlex as applicable so you’re covered by both our promise and their product guarantee.
Clear a path to your fireplace or appliance and remove any fragile items from the mantel or hearth area; for exterior work, ensure we can access the chimney with our ladders and that pets are secured. You do not need to clean the chimney first - that’s part of our process. For rebuilds, we protect your roof, landscaping, and interior with drop cloths and tarps, and we haul away all debris. A live person is available at (571) 701-7519 24 hours a day if you have questions before we arrive.
