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.
Chimney Cleaning in Chantilly, VA
Chimney work in Chantilly is mostly about prefab metal fireplaces built in the 1980s and 1990s, and the galvanized chase covers and caps that have been rusting on top of them for 35 years. The most common call we get from Greenbriar, Chantilly Highlands, and South Riding isn’t a simple sweep. It’s water getting into a wood-framed chase because the cap or crown pan failed, and the homeowner didn’t see any interior staining yet. If you need a chimney cap or crown looked at in Chantilly, call (571) 946-2300 and we’ll put a number in writing before anything starts.
Why Chantilly Homes Are Different
Chantilly’s housing stock is overwhelmingly 1980s and 1990s planned-subdivision construction. Most single-family homes in Greenbriar, Chantilly Highlands, and the neighborhoods around Route 50 and the Air and Space Museum Parkway are Colonial or transitional-style houses built around factory-installed zero-clearance fireplaces from Heatilator, Superior, or Majestic. Those units are now 30 to 40 years old, and the prefab fireboxes themselves were typically rated for 20 to 30 years of service. The chase, the vertical box that encloses the flue, is wood-framed and clad in vinyl or stucco. On top sits a galvanized steel chase cover or cap pan. Northern Virginia winters don’t freeze deep and stay frozen; they cycle through freezing and thawing repeatedly, which stresses galvanized metal seams and screws. Summer humidity then drives condensation on the inside of that steel, and rust-through begins. In Chantilly, a chimney sweep who doesn’t inspect the chase cover, the cap, and the wood framing below them is leaving the actual failure mode unchecked. That’s the dominant repair pattern in this market, not cracked masonry crowns, because most of these homes don’t have masonry chimneys at all.
Our Main Chantilly Services
Most Chantilly homeowners call us about two things: the cap and crown on top of the chase, and the condition of the flue liner or firebox inside it. These three pages cover the work we do most often in this area.
Chimney Cleaning & Sweep in Chantilly
A sweep here is rarely just a sweep. On Chantilly’s prefab systems, we remove creosote from the flue and smoke chamber, but we also inspect the chase cover, cap, and firebox refractory panels while we’re there, because those parts fail before the flue gets dangerously dirty in most of these homes. If you haven’t had the chimney cleaned in two or more years, or you don’t know its history, start here. Chimney Cleaning & Sweep in Chantilly

Chimney Repair in Chantilly
Repair work in Chantilly usually means replacing rusted chase pans, damaged caps, warped dampers, or cracked refractory panels in zero-clearance fireplaces. In older Colonials, we also see flashing failures where the vinyl or stucco chase meets the roof. Every repair we quote includes a camera scan and a written price before we touch anything.

Fireplace Services in Chantilly
Factory-built fireplaces in Chantilly often get ignored because they look fine from the living room while the metal components above the firebox quietly degrade. We inspect, clean, and repair gas log setups, wood-burning fireboxes, and the surrounding chase. If the fireplace smokes, smells damp, or the glass doors don’t seal, this page covers what we find.

Before
AfterChimney Cap & Crown in Chantilly

On Chantilly’s prefab chimneys, the “crown” isn’t a poured concrete slab; it’s usually a galvanized steel chase cover, and the cap is the metal assembly above it. Both are rusting on homes built in the 1980s and early 1990s across Greenbriar and Chantilly Highlands, and water getting through is the reason most of these homeowners eventually need framing repairs, flue liner replacement, or both. That’s why our Chimney Cap & Crown work in Chantilly always starts with a camera scan and a photo record of what’s happening on top of the chase before we recommend anything. If the chase cover is rusted through, we’ll show you the photo. If it can wait a season, we’ll say so and put it in writing.
Cap Replacement
Signs you need it
Rust staining on the chase top, a cap that’s loose or missing, or water dripping into the firebox after rain.
What it costs in Chantilly
Cap replacement in Chantilly typically runs $180 to $340 for the cap and install on a standard prefab chase.
How we do it
We remove the old cap, inspect the chase cover underneath, install the new cap with stainless hardware, and photograph the finished work.
Crown Repair
Signs you need it
Rust-through on the galvanized chase cover, water stains on the ceiling near the chase, or rust flakes in the firebox.
What it costs in Chantilly
Repairing or coating a chase cover in Chantilly typically falls between $220 and $480 depending on whether we’re patching or replacing the pan.
How we do it
We camera-scan the chase cover, patch or replace the pan with materials from Copperfield or Olympia, and seal every seam before documenting the repair.
Crown Coating
Signs you need it
A chase cover that hasn’t rusted through but shows surface corrosion, especially on the screw heads and seams.
What it costs in Chantilly
Chase cover sealing and coating in Chantilly runs roughly $190 to $290 for a standard single-flue chase.
How we do it
We prep the surface, apply a high-grade sealant, and coat the pan seams so water stops pooling against the metal.
What Chimney Cap & Crown Costs in Chantilly
| Item | Typical range in Chantilly |
|---|---|
| Cap replacement (single flue) | $180 - $340 |
| Chase cover repair or replacement | $220 - $480 |
| Crown coating / seam sealing | $190 - $290 |
How long will a replacement chase cover last in Chantilly?
A new galvanized or stainless chase cover typically lasts 10 to 20 years here, but our freeze-thaw cycles shorten that if the seams aren’t sealed correctly. We recommend stainless when the budget allows, and we write the material and warranty into the quote. Call (571) 946-2300 for an exact number.
Can the cap be replaced without touching the siding?
Yes, in most Chantilly chases we work from the roof and never touch the vinyl or stucco siding. If the chase itself is water-damaged, we’ll show you the camera evidence before discussing any siding work.
Chimney Liner & Rebuild in Chantilly

In Chantilly, the flue liners we replace most often are the class-A double-wall metal sections inside prefab chases, not terra cotta tiles in a masonry chimney. These 30 to 40-year-old systems were never designed to last the life of the house, and when the liner or firebox fails, a Chimney Liner & Rebuild is the repair that keeps the fireplace safe to use. We see this constantly in Greenbriar and Chantilly Highlands: a homeowner stops using the fireplace because it smokes or smells, and the camera reveals a failed liner joint or a firebox panel that’s cracked through.
Liner Replacement
Signs you need it
Visible rust on the flue interior, smoke backing into the room, or the fireplace suddenly drafting worse than it used to.
What it costs in Chantilly
Liner replacement in Chantilly for a prefab fireplace typically runs $2,800 to $5,500 depending on flue height and access.
How we do it
We run a camera up the flue, specify the right DuraFlex or HeatShield liner, and install it with a written scope and price before work begins.
Partial Rebuild
Signs you need it
A rusted chase cover that’s let water into the flue, with visible corrosion on the upper sections but a serviceable firebox below.
What it costs in Chantilly
A partial rebuild of the upper flue and chase top typically runs $3,500 to $6,800 in Chantilly.
How we do it
We replace the damaged flue sections and chase cover, leaving the firebox intact, and document every step with photos.
What Chimney Liner & Rebuild Costs in Chantilly
| Item | Typical range in Chantilly |
|---|---|
| Liner replacement (prefab) | $2,800 - $5,500 |
| Partial flue rebuild | $3,500 - $6,800 |
| Firebox repair / panel replacement | $600 - $1,200 |
Does a rusted liner really need to be replaced, or can it wait?
A rusted liner with visible holes or separated joints should not be used. Exhaust gases and heat can escape into the wood chase framing. We’ll show you the camera footage and tell you plainly if it can wait. Get a written price by calling (571) 946-2300.
How do I know I’m not being oversold a new liner?
You get a camera video and still photos of your actual flue, not a generic photo. If the liner is sound, we’ll say so and recommend next steps, which are often just a cleaning. Nothing is quoted without evidence you can see.
