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.

AfterFast, Reliable Fireplace Services Across Chantilly
Fireplace service in Chantilly typically runs $180-$650 depending on whether you need a routine tune-up, refractory panel replacement, or full prefab system repair, and most appointments are scheduled within a few business days with our Fireplace Services team. We’ve been dispatching crews to Chantilly from our Washington, DC office for decades, and we know the difference between a Greenbriar colonial built in 1989 and an Oakton-era home with a factory-built chase. That matters because the fix for a rusted chase cover is nothing like rebuilding a masonry crown, and sending the wrong technician wastes your afternoon.

Why Hearthstone Chimney Co. Is Chantilly’s Preferred Fireplace Services Company
We’ve worked in Chantilly long enough to recognize the Ryan Homes floor plans by the chase cover. Homes in Walney, Sequoia Farms, and Metrowest were built during the same late-1980s through mid-1990s boom, and they share the same prefabricated zero-clearance fireplaces with the same galvanized steel chase covers now hitting 30 years of exposure. That repetition is not a liability. It means our technicians arrive with the right panels, the right liners, and the right expectations instead of figuring it out on your time.
Our background-checked, uniformed technicians complete most jobs in a single visit. No-hassle upfront pricing means the number on the estimate is the number on the invoice. Every job is backed by our 90-Day Done Right Promise in writing, with no arguing and no paperwork to chase down. We’ve been serving local communities for over 42 years, and we plan to be here when your next service is due.

Our Fireplace Services in Chantilly
Gas Fireplace Service
Gas fireplaces in Chantilly townhomes, especially the Greenbriar units built in the early 1990s, often sit unused from April through October. That idle period lets moisture accumulate in the burner assembly and valve train. We clean the burner ports, test gas pressure at the manifold, inspect the thermopile output, and verify the safety shutoff. Annual service prevents the slow degradation that turns a reliable ignition into a cold morning surprise. Even if you barely use it, the seals and gaskets age regardless.
Wood Burning Fireplace
Chantilly’s wood-burning fireplaces are almost exclusively factory-built zero-clearance units in framed chases, not site-built masonry. That distinction changes everything about how we service them. The refractory panels lining the firebox are rated for 20-25 years and begin cracking or warping well past that mark. The metal flue liner, often a HeatShield or similar product, can show heat scoring or seam separation. We inspect with a camera, document what we find, and show you before recommending anything. A sweep alone will not fix a cracked panel.
Fireplace Insert
Many Chantilly homeowners with aging prefab fireplaces choose inserts for efficiency, but the insert must be paired with a liner sized correctly for the unit’s exhaust. We’ve seen inserts dropped into flues with no liner connection, or connected to clay tile that cannot handle the concentrated heat. Our Level-2 inspection measures the flue, documents the connection, and gives you a written specification for what the insert manufacturer actually requires. We work with DuraFlex and Olympia Chimney liner systems, sized and installed to code.
Damper Repair
Prefabricated fireplace dampers in Chantilly homes are typically throat dampers integrated into the firebox assembly, not the cast-iron throat dampers of older masonry. They corrode, they warp, and the seals fail. A damper that does not seat fully costs you conditioned air year-round and can allow downdrafts that carry chimney odors into the living space. We assess whether the damper is repairable or if the entire assembly needs replacement, and we show you the camera footage before you decide.
Firebox Repair
This is where Chantilly’s housing stock shows its age most dramatically. The refractory panels in zero-clearance fireboxes are not permanent. After 25 years of thermal cycling, they crack, spall, or warp out of plane. A cracked panel is not a cosmetic issue. It exposes the surrounding wood framing to direct heat and is a genuine fire hazard. We replace panels with factory-matched or compatible refractory materials, never generic substitutes, and we document the condition of the surrounding chase structure while we’re inside.
Fireplace Conversion
Converting a wood-burning prefab to gas in Chantilly requires more than a burner kit. The flue must be evaluated for the different exhaust characteristics, the firebox must be compatible with the new appliance, and the gas line must meet Fairfax County requirements. We handle the inspection, specify the correct components from Famco or Copperfield where applicable, and coordinate with licensed gas fitters. The result is documented, warranted, and done right the first time.
Trusted Brands We Service in Chantilly
We stock and install professional-grade materials from DuraFlex, HeatShield, Olympia Chimney, Famco, and Copperfield. For Chantilly’s prefab-heavy market, that means we carry the liner systems, chase covers, and termination caps most common to the factory-built units installed here in the 1990s. We don’t substitute builder-grade parts that will fail in five years. Most repairs are completed in a single visit because our trucks are loaded for the specific failures these homes develop.
Common Fireplace Problems We See in Chantilly Homes
- Rusted chase covers letting water into the frame. The original galvanized sheet-metal chase covers on 1980s-90s prefab units are a near-universal failure point in Chantilly. They rust through, water pools inside the framed chase, and the surrounding wood rots long before you see a ceiling stain. We catch this on camera during routine inspection.
- Cracked refractory panels misdiagnosed as creosote buildup. A standard sweep will not fix a firebox panel that has cracked from decades of thermal cycling. We’ve seen homeowners in Sequoia Farms and Walney quoted for repeated sweeps when the real issue was panel failure visible to any camera.
- Third-degree creosote from humid summers. Chantilly’s mid-Atlantic humidity promotes secondary creosote deposits, sometimes tar glaze, on flue liners that sit damp through six months of disuse. A standard brush sweep cannot remove it. We evaluate whether mechanical removal or liner replacement is the appropriate path, and we show you the footage.
- Deteriorated metal flue liners on prefab systems. The aluminum or stainless liners in factory-built units can separate at seams, corrode from condensation, or show heat scoring that indicates over-firing. Camera inspection reveals what a sweep cannot.

FAQs - Fireplace Services in Chantilly
A Level 2 inspection is the correct starting point for any prefab unit over 20 years old, because the failure modes are structural and not visible from the firebox opening. We camera the flue, inspect the chase cover from the roof, and document refractory panel condition. If everything checks out, the sweep is included in the service fee. Call (571) 701-8135 to schedule - estimates are free.
Water enters the framed chase, saturates insulation, rots the surrounding wood structure, and can migrate into interior ceilings and walls before any visible stain appears. By the time you see damage inside, the chase structure may need significant repair. We catch this early with roof-level inspection and show you the chase cover condition on camera. Replacement with a proper galvanized or stainless cover stops the intrusion.
Third-degree creosote, or tar glaze, often cannot be removed by brushing alone and may require rotary mechanical removal or chemical treatment. If the underlying liner is intact and properly sized, we can restore it. If the liner is degraded, improperly sized, or incompatible with your appliance, replacement with a DuraFlex or Olympia Chimney stainless liner is the safer long-term solution. We show you the camera footage and explain which path applies before you decide. Call (571) 701-8135 for an exact quote - estimates are free.
Yes. Moisture accumulation, insect debris in the venting, and slow seal degradation happen whether you light the burner or not. Annual service verifies ignition safety, gas leak integrity, and venting performance. The $89 Seasonal Tune-Up covers this completely. Call (571) 701-8135 to book.
We show you. Every Level-2 inspection ends with dated, labeled photos and video on a tablet we review together before any recommendation is made. No camera evidence, no upsell. In Sequoia Farms, our tech pulled the firebox on a 1991 Ryan Homes colonial and found the original refractory panel cracked in three places and a HeatShield liner on the metal flue showing heat-scored seams - the homeowner had been told by another company it just needed a sweep. We shot camera footage of the cracked panel and the liner scoring, walked the homeowner through it on the tablet, and replaced the panel and lined the flue; no upsell, just what the camera showed. That’s our K.E.Y.S. code: Krafted right, Every time, Your home first, Standing behind it.
