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.
Fast, Reliable Chimney Cap & Crown Across Chantilly
Chimney cap and crown work in Chantilly typically runs $285-$640 for a standard cap replacement and $175-$425 for crown sealing, with most jobs completed in a single visit. For routine maintenance, consider our Chantilly Chimney Cleaning & Sweep service. The bigger issue in this town is age: Chantilly’s 1980s and 1990s subdivisions were built almost entirely with factory-built zero-clearance fireplaces, and the galvanized chase covers on those units are now 25 to 40 years old. When they rust through, water gets into the wood framing before you ever see a stain on the ceiling. Wendell Pike and his crew know exactly what to look for on these Chantilly systems, because we have been opening them up since 1999. Call (571) 518-5470 if you suspect a cap or crown problem, or if you simply want us to take a look before burning season starts.
Why Top Hat Chimney Is Chantilly’s Preferred Chimney Cap & Crown Company
We are not a franchise that rotated into Chantilly last spring. Top Hat Chimney was founded by Wendell Pike in 1999, and Wendell still puts his name on every job. That matters in a place like Chantilly, where homeowners around Greenbriar, Brookfield, and Pleasant Valley have seen enough national outfits quote one number on the phone and a different one at the door. Wendell gives you the price before a single tool comes off the truck. The number on the invoice is the same number you heard on the phone.
Ask anyone on your street. Chantilly homeowners call us because we answer the phone with a live person, around the clock. Not a voicemail box. Not a call center in another state. Often it is Wendell himself picking up. He has been working Chimney Cap & Crown in Chantilly long enough to know which subdivisions have the rusted chase covers, which ones have the cracked refractory panels, and which streets see the most pre-sale inspection requests from the federal contractor turnover near NRO headquarters.
Every job we complete in Chantilly carries the 90-Day Done Right Promise, in writing. If it is not done right, one call brings Wendell back. No arguing, no re-quoting, no charge. That promise is stamped on every invoice. We also run all technicians through background checks, they arrive in uniform, and they give you a real arrival window. If that window slips, we call you.
Our Chimney Cap & Crown Services in Chantilly
Our Chimney Cap & Crown team handles everything from a single-flue cap to full custom crown rebuilds on Chantilly’s larger properties. Here is what we actually do most often in this area.
Cap Installation
A proper cap is the first line of defense for a Chantilly fireplace that rarely gets used. Without one, rain falls straight down the flue and sits in the firebox. Birds and squirrels move in. On prefab units around Greenbriar, we often install caps alongside chase cover replacement because the original covers have rusted through. New stainless steel caps start around $285 installed in Chantilly.

Cap Replacement
If your existing cap is rusted, bent, or missing mesh, replacement is straightforward and usually done same-day. On Chantilly homes with multiple flues, we often replace a single cap with a multi-flue unit that covers the entire crown. If the crown itself is damaged, we may recommend Chimney Repair in Chantilly to address underlying issues. That is a big upgrade for larger properties with several fireplaces, because it simplifies the whole top of the chimney and keeps water out of the concrete crown itself.

Crown Repair
The crown is the concrete slab that caps the masonry around your flue. Once it cracks, water works its way in, freezes, and widens the gaps. On Chantilly’s older masonry chimneys, crown repair usually means grinding out failing material and re-forming the crown with a proper slope so water runs off instead of pooling. We also inspect the flue liner while we are up there, because a cracked crown often hides a compromised liner below it.

Crown Coating
For crowns that are still structurally sound but starting to hairline-crack, a Gelco crown coating seals the surface and buys you real time. This is the most common request we get from Chantilly homeowners who just had a pre-sale Level 2 inspection and need an affordable fix before closing. Coating runs roughly $175-$425 depending on crown size and prep work. It is not a forever fix, but it stops water intrusion immediately and extends the life of the crown by years.

Trusted Brands We Service in Chantilly
Wendell and his crew install and service products from Olympia Chimney, Copperfield, and DuraFlex because those are the brands that hold up to Northern Virginia weather. We keep common cap sizes and crown materials stocked for Chantilly jobs, which means less waiting on a second trip. If you have a Copperfield cap that needs replacement mesh or a DuraFlex liner that is showing wear, we know the product lines and can match what is already on your roof. We also work with HeatShield when a liner needs structural repair rather than full replacement. You will never hear us push a liner job you do not need.
Common Chimney Cap & Crown Problems We See in Chantilly Homes
- Rusted galvanized chase covers on 1980s-1990s prefab units. This is the number one issue in Chantilly subdivisions like Greenbriar. The original galvanized sheet-metal covers installed with factory-built fireplaces rust through at the 20-30 year mark, sometimes sooner if trees shade the chase and keep it damp. We find water dripping onto the firebox and rot starting in the wood framing beneath the vinyl or hardiplank siding.
- Glazed creosote from damp shoulder-season burns. October and March in Chantilly are wet and cool. Homeowners light low, smoldering fires, and those oxygen-restricted burns produce Stage 3 creosote that hardens into a glaze. Standard brushing cannot remove it. That glaze accelerates liner degradation, and once a cap or crown leak lets moisture mix with creosote, you get a corrosive slurry that damages the flue faster.
- Cracked refractory firebox panels found during pre-sale inspections. High turnover from federal contractor relocations near the NRO in Chantilly means buyers and sellers are ordering NFPA 211 Level 2 inspections before closing. Those inspections routinely uncover cracked firebox panels on 25-40 year old factory-built units, and the inspector will flag a missing or rusted cap in the same report. Sellers end up repairing the cap and crown just to get to the closing table.
- Water-stained ceilings below the chase on second floors. By the time a homeowner in Chantilly sees a stain on the bedroom ceiling below the chimney, the chase cover has usually been leaking for months if not longer. The water travels down the framing, so the damage is not where the leak is. A cap and crown inspection is the fastest way to confirm the source before the drywall gets cut open.
Pricing for Chimney Cap & Crown in Chantilly, VA
Here are real numbers for the Chantilly market, not national averages. A standard single-flue stainless steel cap runs $285-$380 installed. A custom cap for a larger masonry chimney runs $425-$640. Crown sealing with Gelco runs $175-$425. Full crown rebuilds run $600-$1,200 depending on access and the condition of the underlying masonry. Multi-flue caps, which we install regularly on Chantilly homes with two or more fireplaces, run $480-$850.
What moves the price is condition and access. A rusted chase cover that requires framing repair before a new cap can go on is a different job than a simple swap. A steep roof pitch on a three-story Chantilly colonial adds ladder work. We give you the number upfront, and we stand behind it. You also get $40 off any repair over $200, and seniors and veterans always get 10% off. Call (571) 518-5470 for an exact quote. The estimate is free.

FAQs - Chimney Cap & Crown in Chantilly
Because the caps and chase covers installed on Chantilly’s 1980s and 1990s factory-built fireplaces were galvanized sheet metal, and galvanized metal rusts through at the 20 to 30 year mark whether you burn or not. Humidity, rain, and shaded chases accelerate it. We regularly replace caps on Chantilly fireplaces that have not had a fire in years, because the cap still failed from weather exposure. Call (571) 518-5470 and we will inspect yours before the next big rain.
Yes. A multi-flue cap covers the entire crown and all the flues at once, which is what we recommend for larger Chantilly properties with two or more appliances venting through the same chimney. It is cleaner than three separate caps, it protects the crown itself, and it is what we installed on a Greenbriar cul-de-sac where a rusted chase cover had already let water into the wood framing. Wendell can tell you if your setup is a candidate, usually just from photos and a quick roof look.
Yes, when the crown is still structurally sound and the leak is coming from hairline cracks, a Gelco crown coating stops water intrusion immediately. We apply it to Chantilly prefab crowns all the time, especially after a pre-sale inspection flags minor crown cracking. It is not a substitute for a full rebuild if the crown is crumbling or the chase cover beneath is rusted through, but for surface-level cracks it works and it costs a fraction of a rebuild. Call (571) 518-5470 to have Wendell assess which situation you have.
A Level 2 inspection is a video scan of the entire flue interior, plus a full exterior check of the cap, crown, chase cover, and firebox. On a 1980s Chantilly prefab unit, the inspector is looking for cracked refractory firebox panels, deteriorated dampers, rusted chase covers, and glazed creosote buildup from damp shoulder-season burns. Any of those findings can hold up a closing. We perform these inspections regularly for Chantilly sellers, and we show you the camera footage and give you a plain-English verdict, every time, no exceptions.
October and March in Chantilly are damp and cool, so fires burn low and smoldering. That produces glazed creosote that hardens inside the flue and holds moisture against the liner. Then, if the cap or crown has even a small leak, that moisture mixes with the creosote and creates a corrosive slurry that eats at the liner and the crown’s underside. Your flue doesn’t care how the fire looks. It cares how it breathes. Catch the cap and crown problem early and you avoid the liner problem entirely.
Call Wendell at Top Hat Chimney
If you live in Chantilly and you have a fireplace that is 20 years old or older, the cap and crown are the first things to check before burning season. You do not need to know what you are looking for. Wendell does. Call (571) 518-5470 for a free estimate, or to book an inspection. A live person answers, around the clock, and it may well be Wendell himself. Once a year, burn or no burn. Chimneys break in the off-season too.
