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.

Why Chantilly Homes Are Different
Chantilly’s residential landscape was built almost entirely during the 1985-2000 Northern Virginia suburban boom. That means the overwhelming majority of homes here contain factory-built, zero-clearance prefabricated metal fireplaces rather than traditional masonry chimneys. These units are now 25-40 years old, at or well past their rated 20-30 year service life. When we clean a Chantilly fireplace, we’re routinely diagnosing cracked refractory panels, rusted-through chase covers, and failing firebox seals alongside standard creosote removal.
The climate compounds the problem. Northern Virginia’s humid summers accelerate rust and moisture infiltration into the metal chase covers and prefab housings that dominate Chantilly’s stock. Then winter’s freeze-thaw cycles, with January lows averaging around 28°F, crack the minimal mortar caps and crown sealants found on the area’s few masonry chimneys. Fireplaces are used enough each winter to build meaningful creosote, but moisture damage from off-season humidity is often the bigger driver of service calls in Chantilly. Many 1990s subdivisions used vinyl or thin-gauge galvanized steel chase surrounds that are now warping, rusting, and allowing water behind drywall. We frequently find this during a routine cleaning visit.
Our Main Chantilly Services
Most Chantilly homeowners call us for one of two reasons: their prefab fireplace has stopped drafting correctly, or water is getting in around the chase cover and cap. These are the services we handle most often in this area.
Chimney Cleaning & Sweep in Chantilly
A standard sweep in Chantilly includes removing creosote from the flue, inspecting the refractory panels, checking chase cover seals, and documenting everything with a camera. Given the age of most prefab units in this area, we pay close attention to firebox integrity and metal fatigue on the chase enclosure. A detailed report with photos comes with every visit. See the full scope on our Chimney Cleaning & Sweep in Chantilly page.
Chimney Repair in Chantilly
Repair work in Chantilly typically involves cracked refractory panels, rusted chase tops, damaged caps, or water-damaged framing around the chase enclosure. We source materials from manufacturers like Olympia Chimney and Famco so parts match the original system. Every repair gets a written scope and a written warranty before work begins. Learn more on our Chimney Repair in Chantilly page.

BeforeAfterChimney Cap & Crown in Chantilly
Chimney cap and crown work in Chantilly is driven by one dominant problem: water. The galvanized and aluminum chase covers installed on most 1990s-era prefab chimneys are now rusting through, warping, and letting moisture into the chase enclosure and behind drywall. A crowned masonry chimney, rare in Chantilly but present on some older or custom homes, suffers the same fate through freeze-thaw cracking of the mortar crown. If water is getting in, a new cap or a Chimney Cap & Crown is the fix. Replacing a rusted chase cover or installing a properly sized cap stops water damage before it reaches framing and drywall.
Cap Installation
Signs you need it
You see rust streaks running down the chase, water staining on the ceiling near the fireplace, or the existing cap is missing, bent, or the wrong size for the flue.
What it costs in Chantilly
A standard single-flue cap installation in Chantilly typically runs $250-$500 depending on flue size and access.
How we do it
We measure the flue, select a correctly sized cap from Olympia Chimney or Famco, fasten it securely, and photograph the finished installation.
Chase Cover Replacement
Signs you need it
The galvanized steel top of the chase enclosure is rusted through, warped, or no longer sheds water, and you may see interior water staining below the fireplace.
What it costs in Chantilly
Chase cover replacement in Chantilly typically runs $500-$1,000 for a custom-fabricated stainless or aluminum cover.
How we do it
We remove the old cover, fabricate or order a correctly pitched replacement, seal the seams, install the new cover, and document with photos.
Crown Repair
Signs you need it
The mortar crown is cracked, spalling, or missing sections, and water is pooling on top of the chimney instead of draining off.
What it costs in Chantilly
Crown repair in Chantilly typically starts around $400 and runs up to $900 for a full recoat with a flexible sealant.
How we do it
We clean the crown, fill cracks, apply a waterproof membrane or crown coat, and re-slope the surface if needed so water drains away from the flue.
What Chimney Cap & Crown Costs in Chantilly
| Item | Typical range in Chantilly |
|---|---|
| Single-flue cap installation | $250-$500 |
| Chase cover replacement | $500-$1,000 |
| Crown repair with sealant | $400-$900 |
How long does a chase cover last in Chantilly?
A galvanized steel chase cover lasts 10-15 years in Chantilly’s humid climate before rust sets in. Stainless steel lasts 20 years or more and is worth the cost when the old cover has already failed.
Do I need a new cap if my chimney is prefab?
Yes. Prefab chimneys need caps sized for their air-cooled metal flues, and a missing or wrong-sized cap lets rain, leaves, and birds into the chase enclosure. We measure every flue before ordering.
Chimney Liner & Rebuild in Chantilly
Chimney liner and rebuild work in Chantilly looks different from older neighborhoods because most chimneys here are air-cooled prefab metal flues, not clay tile or masonry. The liner problems we see in Chantilly are typically rusted-through flue sections, separated seams, or liners damaged when a chase cover failed and let water in. Masonry chimneys, where present, face spalling brick and failing mortar joints from freeze-thaw cycles. A proper Chimney Liner & Rebuild stops flue gases from leaking and restores the structure’s integrity.
Stainless Steel Liner
Signs you need it
You see rust flakes inside the existing liner, the prefab flue sections are separating, or a camera inspection shows holes or corrosion.
What it costs in Chantilly
A stainless steel liner system in Chantilly typically runs $1,500-$3,500 including installation and connections.
How we do it
We size the liner, run it through the existing flue, insulate where needed, connect it at the appliance and termination, and document the full install with a camera.
Liner Replacement
Signs you need it
The old clay tile or metal liner is cracked, spalling, or has gaps that allow flue gases to leak into the chase or the home.
What it costs in Chantilly
Full liner replacement in Chantilly typically falls between $2,000 and $5,000 depending on length, bends, and access.
How we do it
We remove the failed liner, inspect the chase, install the new liner with proper terminations, and provide a written warranty along with photos.
Partial Rebuild
Signs you need it
The top rows of brick are spalling, the mortar cap has failed, or the chimney above the roofline is leaning or loose.
What it costs in Chantilly
Partial rebuilds in Chantilly typically start around $2,000 and run up to $6,000 depending on how many courses of brick need replacing.
How we do it
We remove the damaged section, rebuild with matched brick and mortar, install a new cap or crown, and photograph the finished work.
What Chimney Liner & Rebuild Costs in Chantilly
| Item | Typical range in Chantilly |
|---|---|
| Stainless steel liner system | $1,500-$3,500 |
| Full liner replacement | $2,000-$5,000 |
| Partial chimney rebuild | $2,000-$6,000 |
Can I keep using my fireplace with a damaged liner?
No. A damaged liner can leak flue gases into the chase cavity or the home. If a camera inspection shows liner damage, stop using the fireplace until it is repaired or replaced.
How do I know if my prefab chimney needs a new liner?
A camera inspection shows rust holes, separated seams, or failing joints. On Chantilly homes past the 25-year mark, we recommend a Level 2 camera inspection before each burning season.
