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.

AfterTrusted Chimney Liner & Rebuild for Ashburn Homeowners
A chimney liner and rebuild in Ashburn, VA typically costs between $1,800 for a basic stainless steel liner replacement and $8,500 or more for a full chimney rebuild, with most projects completed in one to two days. Hearthstone Chimney Co. has been serving Ashburn homeowners since 1984, and our Level-2 camera inspections give you photos you can see and a plain-English verdict before any work begins. Call (571) 701-8135 to speak with a live person any hour of the day, or read on to understand exactly what your chimney needs and what it will cost.
We’ve been in Ashburn long enough to know the chimneys here. The clay flue tiles in Brambleton’s 1990s-built homes crack from thermal shock after decades of heating cycles. The unlined masonry in older Great Falls farmhouses lets exhaust gases seep into wall cavities. In South Riding, we’ve replaced dozens of corroded flexible liners that were the wrong alloy for wood-burning appliances. Russell Haines started this company in 1984 because he believed homeowners deserved a square deal: photos they could see, pricing with no surprises, and a promise in writing that the job would be done right. That hasn’t changed in 42 years.
Our technicians are background-checked, uniformed, and carry professional-grade materials from Olympia Chimney, Famco, Copperfield, and DuraFlex. Most liner replacements and partial rebuilds finish in a single visit. You get no-hassle upfront pricing, the 90-Day Done Right Promise in writing, and the certainty that we’ll be there when we say.
What Our Chimney Liner & Rebuild Service Includes
Stainless Steel Liner
A stainless steel liner is a continuous metal flue installed inside your chimney to contain combustion gases and protect the masonry from corrosive condensation. In Ashburn, we install stainless steel liners most often when clay flue tiles have cracked or when a chimney was built without a liner at all, which is common in homes constructed before 1980 in neighborhoods like Belmont and Wolf Trap. Hearthstone Chimney Co. uses 316Ti or 304 alloy liners from Olympia Chimney and DuraFlex, sized precisely to your appliance’s BTU output and venting requirements. We pull a camera through the full length after installation to verify every joint and seam.
Flexible Liner
A flexible liner is a corrugated stainless steel tube that navigates offsets and bends in chimneys where a rigid liner won’t fit, such as the tight flue passages in some Reston townhomes or historic Oakton properties with shifted masonry. You need a flexible liner when your chimney has a significant offset, when you’re relining from the bottom up through a damper throat, or when structural constraints make rigid installation impossible. We specify only UL-listed flexible liners with proper insulation blankets to maintain flue temperature and prevent creosote buildup, and we never use the thin-gauge products that some installers push to cut costs.
Liner Replacement
Liner replacement becomes necessary when your existing liner has deteriorated beyond repair, whether from age, improper original installation, or damage from a chimney fire. In Ashburn, we replace liners most frequently in homes where previous owners installed the wrong liner material, such as aluminum liners in wood-burning systems, which corrode rapidly. Our replacement process starts with a full Level-2 inspection including video documentation of the damage, followed by precise measurement and custom fabrication of your new liner system. We handle the permit coordination with Loudoun County and provide the photo report and written verdict before any contract is signed.
Partial Rebuild
A partial rebuild addresses specific sections of chimney failure, typically the crown, the top several courses of brick, or a deteriorated smoke chamber, without the cost of full reconstruction. In Ashburn’s freeze-thaw climate, we see partial rebuilds most often where water intrusion has spalled the exterior brick above the roofline, particularly on north-facing exposures in neighborhoods like Cascades and Brambleton. Hearthstone technicians rebuild with matching brick where possible, pour new concrete crowns with proper drip edges and expansion joints, and always verify that the underlying liner remains intact before closing up. Most partial rebuilds complete in one day with the crew protecting your roof and landscaping throughout.
Full Chimney Rebuild
A full chimney rebuild is required when the masonry structure has compromised integrity throughout, from foundation to crown, often from long-term water damage, settlement, or catastrophic failure such as a lightning strike or house fire. We’ve done full rebuilds in Ashburn on century-old farmhouses near Great Falls and on chimneys that simply reached end-of-life after 80 years of Virginia weather cycles. Our rebuilds include proper footings, code-compliant clearances to combustibles, new flue liners sized to modern appliance standards, and flashing integration that actually sheds water. Russell Haines reviews every full rebuild plan personally, and we document progress with photos at each stage.
Liner Repair
Liner repair is a targeted fix for localized damage, such as a cracked tile at the top of the flue, a deteriorated joint between liner sections, or minor corrosion spots in a metal liner that don’t warrant full replacement. In Ashburn, we’ve saved homeowners significant expense by repairing rather than replacing liners that were fundamentally sound except for one or two problem areas. We use HeatShield cerfractory sealant for appropriate clay tile repairs and specialized patching compounds for stainless steel, always with the understanding that repair is only recommended when we can document that the remaining liner meets safety standards. If we can’t stand behind a repair with our 90-Day Done Right Promise, we’ll tell you straight and quote replacement instead.

Brands We Service for Chimney Liner & Rebuild
We’ve installed and serviced hundreds of Olympia Chimney liner systems across Loudoun and Fairfax counties, and we stock their full range of rigid and flexible stainless steel components. Their 316Ti alloy liners hold up particularly well in Ashburn’s mixed-hardwood burning environment where flue gas condensation can be aggressive. We also carry Famco termination caps and adaptors, which we specify when the chimney top needs proper rain protection and draft control to match a new liner installation.
Copperfield chimney supplies have been in our inventory since the 1990s, and their firestop assemblies and insulation products meet the strict clearance requirements we encounter in multi-story Ashburn homes with chimneys passing through finished attics. DuraFlex flexible liners are our go-to for tight offset installations, with their proprietary corrugation profile that maintains structural integrity through bends that would kink lesser products. Whether you have one of these brands already or need guidance on what system suits your chimney, we can help. Every recommendation starts with what the camera shows, not with what we have in the truck.
Signs You Need Chimney Liner & Rebuild Right Now
- White staining or efflorescence on exterior brick indicates that moisture is migrating through the masonry, which in Ashburn’s climate usually means a compromised liner is allowing condensation to saturate the chimney structure. Left unaddressed, this freeze-thaw cycling spalls brick faces and deteriorates mortar joints from the inside out, turning a liner problem into a rebuild project.
- Flakes of clay tile in the firebox or cleanout are pieces of your flue liner that have detached due to thermal shock, age, or previous chimney fire damage. Once tiles begin shedding, the underlying masonry is exposed to corrosive flue gases and the risk of carbon monoxide leakage into living spaces increases substantially.
- Smoke or odors entering rooms when the fireplace is not in use suggests a liner breach or negative pressure issue that allows downdrafts to carry chimney air into your home. In Ashburn’s newer tight-construction homes in South Riding and Brambleton, this often couples with inadequate makeup air and a deteriorated liner to create persistent air quality problems.
- Visible cracks or gaps in the chimney crown allow water directly into the flue system and onto the liner, accelerating corrosion of metal liners and freeze-thaw damage to clay. The crown is your chimney’s umbrella, and when it fails, everything beneath it deteriorates faster, especially during Virginia’s wet winters and spring temperature swings.
- A recent home inspection flagged the chimney for “further evaluation” means a generalist inspector saw something they couldn’t fully assess, and the burden of proof now falls on you as the homeowner or buyer. We’ve performed hundreds of these follow-up inspections in Ashburn real estate transactions, and our Level-2 camera documentation either clears the concern or defines exactly what repair is needed with costs attached.
Our Chimney Liner & Rebuild Process - Step by Step
- 1
Schedule and confirm. When you call (571) 701-8135, a live person answers, checks availability, and confirms your appointment with a two-hour window. We ask about your chimney’s age, fuel type, and any symptoms you’ve noticed so our technician arrives prepared with the right equipment and materials.
- 2
Level-2 inspection with camera documentation. Our technician conducts a full interior and exterior examination, including video scanning of the flue from top to bottom. You see the footage in real time on a tablet screen, and we explain what we’re seeing in plain English, not contractor jargon. The inspection produces dated photos and a written verdict.
- 3
Upfront estimate with options. If repair or replacement is needed, we present a detailed estimate with line-item pricing before any work begins. For liner replacement, you’ll see separate costs for liner material, insulation, termination, and labor. For rebuilds, we break out masonry, scaffolding if needed, and liner integration. The number on the estimate is the number on the invoice.
- 4
Professional execution with site protection. Our background-checked, uniformed technicians protect your floors, furniture, and landscaping before starting work. We use HEPA filtration when cutting masonry indoors, and we work methodically through the agreed scope. Most liner replacements and partial rebuilds complete in a single visit; full rebuilds are scheduled with clear milestones.
- 5
Final inspection, documentation, and written guarantee. We camera-verify every liner installation and photograph completed rebuild work. You receive copies of all documentation, a maintenance schedule, and the 90-Day Done Right Promise in writing. If anything isn’t right, we come back. No paperwork to file, no arguing.
How Much Does Chimney Liner & Rebuild Cost in Ashburn?
A typical stainless steel liner replacement in Ashburn runs $1,800 to $3,400 for a straightforward single-flue installation with standard access, so you can see how much chimney liner and rebuild costs in our market. Flexible liner installations in tight chimneys range from $2,200 to $4,100 depending on length, diameter, and whether insulation blanket is required by code. Partial rebuilds, including crown replacement and top course masonry repair, generally fall between $1,500 and $3,800. Full chimney rebuilds start around $6,500 and can exceed $12,000 for tall structures with complex scaffolding requirements or matching of discontinued brick.
Several factors move these numbers. Chimney height and accessibility matter: a three-story colonial in Belmont costs more than a single-story ranch in Chantilly. The number of flues, appliance connections, and whether the fireplace is a prefab unit or site-built masonry all affect material and labor. Permit fees in Loudoun County add a modest but necessary line item. And the condition of the existing structure, if a simple liner replacement reveals hidden water damage during inspection, may expand the scope.
To avoid overpaying, get a camera inspection first. We’ve seen Ashburn homeowners quoted full rebuilds by companies that never looked inside the flue, when a $2,400 liner replacement would have solved the problem. Conversely, we’ve caught unlined chimneys that were about to receive cheap cap repairs instead of the liner they desperately needed. Our free estimate includes the Level-2 inspection documentation, so you have evidence you can verify independently. Nothing is recommended without photo proof you can see for yourself, and we’ll tell you plainly when work can safely wait.
Standing offers that apply: $50 off any repair over $250, free second opinion on any written estimate, and a permanent 5% senior and veteran discount. The $89 seasonal tune-up includes inspection and can identify liner issues before they become expensive emergencies.
