We’ve been answering calls from Chantilly homeowners for over 42 years, and our dispatch team coordinates scheduling from our Washington, DC office so crews are routed efficiently to subdivisions across the area. Whether you’re in Chantilly Highlands off Route 50, Westfield near the Dulles Airport corridor, or Deer Park south of Braddock Road, we know the housing stock because we’ve worked inside it. The prefabricated fireplaces installed by production builders in the 1980s and 1990s are now hitting their failure window, and the symptoms homeowners notice - smoky drafts, water stains, rust particles in the firebox - often trace back to liner deterioration or chase cover failure that a standard sweep won’t fix.

Why Hearthstone Chimney Co. Is Chantilly’s Preferred Chimney Liner & Rebuild Company

Our reputation in Chantilly was built one job at a time, mostly through neighbors telling neighbors after we pulled a camera out and showed them exactly what was wrong. We don’t quote rebuilds from the roof. Every recommendation starts with a Level-2 camera inspection that ends with photos you can see and a plain-English verdict. That documentation matters in Chantilly, where many homes have factory-built fireplaces with concealed damage behind sheet-metal chase covers.

Response time to Chantilly is typically next-day or within 48 hours for liner and rebuild consultations, with dispatch coordinated from our metro office. We carry the K.E.Y.S. values code on every job: Krafted right, Every time, Your home first, Standing behind it. The 90-Day Done Right Promise backs every liner installation and rebuild in writing - if it’s not right, we make it right, no arguing, no paperwork chase.

Our technicians are background-checked and uniformed, and most liner replacements and partial rebuilds are completed in a single visit with no-hassle upfront pricing. The number on the estimate is the number on the invoice. We’ve earned strong reviews from Chantilly customers specifically for refusing to recommend work without camera evidence, and for explaining why a job can safely wait when that’s the honest answer.

Our Chimney Liner & Rebuild Services in Chantilly

Stainless Steel Liner Installation

Stainless steel liners are the standard for relining deteriorated clay-tile flues in Chantilly’s older colonials, and for upgrading prefab systems where the original factory liner has failed. We use DuraFlex and Olympia Chimney stainless products, sized precisely to your appliance’s BTU output and venting requirements. In Chantilly Highlands and Westfield, we’ve relined dozens of systems where high-efficiency gas inserts were vented into original clay flues never designed for condensing temperatures - the corrosive condensate eats the flue from the inside, so a liner that looks acceptable from the roof can be spalling and failing at the smoke chamber. Our camera finds it before we quote anything.

Flexible Liner Installation

Flexible liners solve the access problem in Chantilly’s tighter chimney constructions, particularly in transitional-style homes built in the 1990s with offset flues or limited cleanout access. We install DuraFlex flexible stainless liners that navigate offsets without breaking the flue’s continuous draft path. This matters in Deer Park and surrounding subdivisions where production builders prioritized speed over serviceability - the offset that saved the builder ten minutes now complicates every liner pull unless you have the right equipment and the patience to use it. Flexible liner installation in Chantilly typically runs $2,200-$3,800 depending on flue length and offset complexity.

Liner Replacement for Prefabricated Fireplaces

Most Chantilly chimney liner work starts as an aging prefab system issue, not a masonry problem. The 1980s-90s production-builder Heatilator and Heat-N-Glo fireplaces in subdivisions like Chantilly Highlands, Westfield, and Deer Park are now 25-40 years old, and their galvanized chase covers have often rusted through, letting water rot the wood framing inside the chase - a failure mode that looks like a simple sweeping call until the cover is pulled. In Chantilly Highlands, we pulled a rusted-through galvanized chase cover on a 1988 Heatilator and found the surrounding wood framing inside the chase rotted where ice-dammed water had been running in for seasons; the flue liner was also deteriorated and the firebox refractory panels were cracked. We replaced the chase cover with a copper field-fabricated unit, installed a new stainless steel liner, and rebuilt the firebox panels, showing the homeowner the camera footage before recommending any of it. After the rebuild, the draft was restored and the system passed a Level 2 inspection.

Partial Chimney Rebuild

Partial rebuilds address the damage that camera inspections reveal beyond simple liner failure. In Chantilly, clay-tile flue liners in older homes crack at the mortar joints after repeated freeze-thaw cycles, and because the adjacent original mortar is often already spalling, a simple liner replacement can turn into a partial rebuild once the camera reveals the full length of the damage. We rebuild from the roofline down to sound masonry, or from the smoke chamber up, matching existing brick and mortar where possible. Partial rebuilds in Chantilly typically range $3,500-$6,500. We don’t guess at scope - the camera shows us exactly where sound structure ends and rebuild begins.

Full Chimney Rebuild

Full rebuilds are rare in Chantilly compared to older Northern Virginia cities, but necessary when freeze-thaw damage, water intrusion, or deferred maintenance have compromised the structural shell. When a full rebuild is genuinely required, we document the structural failure with photos, explain every stage of the work, and provide fixed-price quoting. Full rebuilds in Chantilly generally run $6,500-$12,000.

Liner Repair

Not every liner problem requires full replacement. Localized cracks, joint gaps, or minor spalling in otherwise sound clay flues can sometimes be addressed with HeatShield cerfractory sealant or targeted stainless repair sleeves. We evaluate liner repair candidacy strictly by camera - if the damage is too extensive for repair to be safe, we’ll show you why and quote replacement. Liner repairs in Chantilly run $800-$1,800 when the flue is structurally sound enough to qualify.

Trusted Brands We Service in Chantilly

We work exclusively with professional-grade materials - no builder-grade substitutes that fail in five years. For liner and rebuild work in Chantilly, we stock and install DuraFlex flexible and rigid stainless liners, HeatShield cerfractory resurfacing products, and Olympia Chimney components. We also source Gelco chase covers and caps when a prefab system needs weather protection that outlasts the original galvanized sheet metal. Having these materials on hand means faster turnaround for Chantilly homeowners, especially during the pre-burning-season rush when every day of delay matters.

Common Chimney Liner & Rebuild Problems We See in Chantilly Homes

• Clay-tile flue liners cracked at mortar joints after freeze-thaw cycling. Northern Virginia’s winter temperature swings repeatedly across the 32°F threshold, and the resulting expansion and contraction spalls mortar in Chantilly’s older clay flues. The cracks aren’t always visible from the firebox - our camera finds them at the smoke chamber and above.
• Galvanized chase covers rusted through on 1980s-90s prefab units. The original sheet-metal covers on Heatilator and Heat-N-Glo fireplaces in Chantilly subdivisions have reached the end of their functional life. Once rust breaches the metal, ice-storm water drives straight into the chase framing, and the damage compounds every winter.
• High-efficiency appliances vented into flues never designed for condensing temperatures. Chantilly homeowners who upgraded to efficient gas inserts or boilers often didn’t know the original clay flue couldn’t handle the acidic condensate. The flue deteriorates from the inside, producing draft problems and carbon monoxide risk before exterior damage is obvious.
• Refractory panels cracked and fireboxes warped in aging prefab systems. The factory-built fireplaces installed across Chantilly in the 1980s and 1990s have refractory panels rated for roughly 20-25 years of normal use. Many are now well past that lifespan, with cracked panels that no longer reflect heat properly and warped fireboxes that leak combustion gases.
