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.

We’re Hearthstone Chimney Co., and we’ve been serving Northern Virginia homeowners for over 42 years. Our dispatch and scheduling runs from our Washington, DC office, with crews working Ashburn neighborhoods daily. Call (571) 701-8135 - a live person answers, 24 hours a day.
Ashburn’s housing story is unique. This was farmland before 1990, then Loudoun County exploded into planned communities like Ashburn Farm, Ashburn Village, and Broadlands. Nearly every home went up between 1993 and 2008 with factory-built zero-clearance prefabricated fireplaces - Heatilator, Heat & Glo, or Superior units - not traditional masonry chimneys. Those systems are now hitting their 20-30 year lifespan. The service conversation here is fundamentally different than in older Northern Virginia towns. We’re not sweeping soot from 1920s brick flues. We’re inspecting metal firebox panels for cracks, checking refractory components for deterioration, and replacing rusted chase covers before they let water destroy the flue assembly.
Why Hearthstone Chimney Co. Is Ashburn’s Preferred Chimney Liner & Rebuild Company
We’ve earned our reputation in Ashburn one inspection at a time. Homeowners here talk to neighbors. They compare notes at Broadlands community events or Ashburn Village HOA meetings. When a family in Belmont Country Club tells another family that we showed them camera footage of their cracked refractory panels before quoting a dime, that carries weight. No upselling. No mystery. Photos they can see, a plain-English verdict.
Our Level-2 camera inspections end with documented images and a written report. The 90-Day Done Right Promise backs every job in writing - if it’s not right, we make it right, no paperwork and no arguing. That’s the Keystone Standard: Krafted right, Every time, Your home first, Standing behind it.

Our Chimney Liner & Rebuild Services in Ashburn
Stainless Steel Liner Installation
Ashburn’s prefab metal flue liners corrode faster than homeowners expect, especially when rusted chase covers let freeze-thaw moisture into the assembly. We install professional-grade stainless steel liner systems from DuraFlex and Olympia Chimney - materials rated for the temperature swings and humidity of mid-Atlantic winters. A typical stainless steel liner replacement in Ashburn runs $2,200-$3,800, including removal of the damaged factory liner and proper connection to the appliance. We size every system to the specific firebox or insert, because an improperly sized liner creates draft problems that show up as smoke in the living room or carbon monoxide risk.
Flexible Liner Systems
Some Ashburn homes - particularly townhomes in Ashburn Farm with offset flue passages or tight chase clearances - need flexible liner systems that navigate bends rigid pipe cannot. We use DuraFlex flexible stainless for these applications, installed with proper support and termination per manufacturer specs. Flexible liner work in Ashburn typically falls between $2,400-$4,100 depending on chase height and access. Every installation includes a post-install smoke and draft test.
Liner Replacement for Prefab Fireplaces
This is the core need in Ashburn. Those 1990s-2000s Heatilator, Heat & Glo, and Superior units came with factory metal flue liners that simply weren’t built to outlast the mortgage. We replace the entire flue liner assembly, inspect the firebox panels and refractory brick, and document everything with camera footage before recommending any additional work. Liner replacement alone in Ashburn typically costs $1,800-$3,200. If the firebox panels are cracked - and in our experience, they often are in 25-year-old units - we’ll show you the damage and quote panel replacement separately. Nothing gets added without evidence you can see.
Partial and Full Chimney Rebuild
When a prefab firebox is compromised beyond panel replacement, or when a masonry chimney in one of Ashburn’s earlier-built homes has suffered structural failure, rebuild becomes necessary. Partial rebuilds - firebox reconstruction, chase rebuild, or crown replacement - range from $3,200-$5,500 in Ashburn. Full chimney rebuilds, rare here but needed when masonry stacks have been neglected or improperly modified, run $5,800-$7,800. We use professional-grade materials from Gelco and Copperfield, and every rebuild carries the 90-Day Done Right Promise in writing.
A family in Broadlands called us after their first season burning in a home they’d just bought; the firebox panels on their original Heatilator were cracked and the chase cover had rusted through at the seams. We ran a Level 2 inspection with camera footage and showed them the failing refractory, then replaced the damaged panels and installed a new stainless steel liner system. They could see every defect before we quoted a single repair.

Trusted Brands We Service in Ashburn
We work exclusively with professional-grade materials - no builder-grade substitutes that fail in five years. Our trucks stock DuraFlex and Olympia Chimney liner components, Gelco chase covers and caps, and Copperfield refractory and rebuild materials so Ashburn homeowners aren’t waiting on parts. Famco termination fittings round out our prefab system inventory. These are the brands that professional sweeps specify when they’re doing the job for their own homes. Fast turnaround matters in Ashburn, where October and November cold snaps drive sudden demand. Having the right parts on the truck means we complete most liner replacements and firebox rebuilds in a single visit.
Common Chimney Liner & Rebuild Problems We See in Ashburn Homes
- Cracked firebox panels in aging prefab units. Heatilator, Heat & Glo, and Superior fireboxes installed during Ashburn’s 1993-2008 construction boom were never designed for decades of regular use. Refractory panels crack, allowing heat to reach the metal cabinet and surrounding framing. We find this in homes across Ashburn Village and Broadlands where original owners are still burning, or where new buyers have started using dormant fireplaces.
- Rusted or seam-split chase covers letting moisture destroy flue assemblies. Ashburn’s freeze-thaw cycles are brutal on the sheet-metal chase covers that top prefab chimneys. Once seams split, water runs directly onto the metal flue liner, accelerating corrosion and creating drafting problems that a homeowner might mistake for a “smoky fireplace.” This is a more common failure point here than crown or mortar cracking on masonry stacks.
- Improper venting of gas logs or inserts into stacks never designed for them. Homeowners or prior contractors in Ashburn frequently vent new appliances into existing prefab flues without verifying compatibility. The result is improper draft, dangerous creosote accumulation in metal liners, and conditions that only a Level-2 camera inspection reveals. We document these violations with photos and specify the correct liner or rebuild solution.
- Refractory deterioration in lightly used fireplaces now seeing heavy use. In neighborhoods like Belmont Country Club, large builder-grade homes sold with upscale-looking surrounds concealing mid-range prefab units. Original owners never burned heavily, but as homes turn over, new owners fire them up in systems with 25-year-old refractory. Post-sale inspection calls are extremely common in Ashburn’s resale market, and we routinely find panels that should have been replaced years ago.

FAQs - Chimney Liner & Rebuild in Ashburn
Most 1990s Ashburn prefab fireplaces have a factory metal flue liner that can be replaced independently of the chase structure. We run a Level-2 camera inspection to confirm the liner’s condition and check whether the firebox panels, refractory, or chase cover also need attention. Full rebuild is only necessary if the firebox cabinet itself is compromised or the chase structure has suffered moisture damage beyond panel replacement. Call (571) 701-8135 to schedule an inspection - estimates are free, and you’ll see the camera footage before we quote any work.
Level 1 covers visible, accessible portions of a chimney you use regularly with no changes to the system - rare for Ashburn’s 20-30 year old prefab units. Level 2, which we recommend for virtually every Ashburn liner or rebuild inquiry, adds camera inspection of the full flue interior, attic and basement access where applicable, and documented photo evidence - required by NFPA 211 for real estate transactions, new appliance installations, or suspected damage. Level 3 involves demolition of building materials to access concealed areas, and we only recommend it when Level 2 reveals evidence of serious structural compromise. Most Ashburn homeowners need Level 2. Call (571) 701-8135 to book one.
Rusted chase covers are a real problem in Ashburn, not cosmetic. Our freeze-thaw cycles open seams that let water run directly onto the metal flue liner and firebox top, accelerating corrosion and creating drafting problems. We’ve replaced chase covers in Ashburn Farm and Broadlands where rust had completely penetrated the metal, allowing water to pool in the chase and damage the liner below. A new Gelco or Copperfield chase cover typically runs $650-$1,200 installed. Call (571) 701-8135 and we’ll inspect it with the camera - you’ll see exactly what’s happening inside.
Yes. We show you camera footage of your flue interior, firebox panels, and chase cover before recommending any work. Our Level-2 inspection produces photos you can see and a plain-English verdict - documented like an engineer, explained like a craftsman. If your liner is intact and your only issue is a cracked chase cover, we’ll tell you that. If the liner is sound but firebox panels are failing, we’ll show you the cracks and quote panel replacement only. No work is recommended without evidence you can verify yourself. The 90-Day Done Right Promise backs whatever we do - in writing, no arguing. Call (571) 701-8135 for an inspection that puts you in control.
Yes, especially in Ashburn. Dormant prefab systems suffer the same freeze-thaw damage to chase covers and the same refractory deterioration from temperature cycling - problems that don’t require active burning to develop. Many Ashburn homeowners who “never use the fireplace” call us after a home inspection reveals hidden damage, or after a new buyer’s inspector flags issues that could have been caught years earlier. An unused system with a corroded liner or cracked panels is still a safety hazard if future owners or guests light a fire. Call (571) 701-8135 for a Level-2 inspection - $250-$350, with photos you keep whether or not you hire us for repairs.
Done right - and we stand behind it. A square deal: no surprises on the bill. We’ll be there when we say. Photos you can see, a plain-English verdict. In writing, no arguing.
