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.

AfterTrusted Chimney Cap & Crown for Ashburn Homeowners
A cracked chimney crown or a missing cap is not a cosmetic issue. In Ashburn, where freeze-thaw cycles run from November through March, water gets into the crown’s hairline cracks, freezes, expands, and turns a $400 repair into a $3,000 rebuild in two winters. Corrine Halstead and the team at Level Two Chimney Ashburn have repaired or replaced caps and crowns on more than 38,000 chimneys since 2009, every one documented with a camera before and after. We serve Ashburn homeowners with written pricing before any work starts, and you can reach a live person at (240) 220-9412 any hour of the day or night.
Key Takeaways:
- A chimney cap and crown are your first defense against water damage, animal entry, and chimney fire risk.
- Repair costs in Ashburn typically run $150-$800; full replacement with a quality cap runs $350-$1,200.
- Every Level Two job includes a camera-scan inspection and a documented photo record under Haven Standard Clause 4.
- Written price, written scope, written warranty, delivered before anyone starts work.
What Our Chimney Cap & Crown Service Includes
Your chimney’s cap and crown sit at the very top of the system, where they take the full force of Ashburn’s weather. The crown is the concrete or mortar slab that seals the top of the chimney around the flue. The cap is the metal cover that sits above the flue opening. Together, these two components keep rain, snow, animals, and debris out of your fireplace system. When either one fails, the damage works its way down: into the flue liner, into the smoke chamber, and eventually into the masonry itself. Here is what we do, component by component.
Chimney Cap Installation
A chimney cap is a metal cover placed over the top of your flue to keep rain, birds, squirrels, and leaves out while still allowing smoke and gases to escape. Many older Ashburn homes, especially those built before 2000 in neighborhoods like Ashburn Farm and Ashburn Village, either never had caps installed or have caps that have rusted through. You can learn more about our Chimney Cap & Crown in Ashburn. Our technicians install caps sized precisely to your flue dimensions, not just whatever fits from the truck. Every installation includes a camera scan of the flue before the cap goes on, because sealing the top without checking what is below is how you trap problems instead of preventing them.
Chimney Cap Replacement
If your existing cap is bent, rusted, or has mesh that is pulling away from the frame, it is doing more harm than good. A damaged cap can actually restrict draft, forcing smoke back into your living room instead of up and out. We remove the old unit, inspect the flue crown beneath it, and install a replacement cap rated for northern Virginia weather. We stock caps from Famco and Copperfield, and Corrine Halstead personally reviews every replacement recommendation before it goes to you in writing.
Chimney Crown Repair
The crown is the mortar or concrete slab at the top of the chimney that slopes away from the flue to shed water. When it cracks, water seeps in and the freeze-thaw cycles we get every winter in Ashburn widen those cracks fast. We can repair minor crown damage with crown coat sealant or full crown rebuild work when the damage has gone too far. Our techs will show you photos of your crown from the roof or from the camera before recommending a material, and the written estimate always distinguishes between what must be done this season and what can safely wait.
Chimney Crown Coating
Crown coating is a flexible, waterproof sealant applied over the existing crown to close small surface cracks and prevent moisture intrusion. It works on crowns that are still structurally sound but are starting to show their age. We use crown-specific coating products and apply them under the right conditions, not in rain or when temperatures are below 45 degrees. This is often the single most cost-effective service we offer in Ashburn, because it buys ten-plus years of crown life for a fraction of a rebuild.
Multi-Flue Cap Installation
If you have two flues, maybe a wood-burning fireplace and a furnace vent, a multi-flue cap covers both openings under one custom unit. These caps are more complex to install because they require accurate measurement across the full width of the chimney crown. We measure, fabricate, and install multi-flue caps that fit your exact crown dimensions. Ashburn homes with dual-flue setups built in the last 15 years are especially common, and this is a service we handle several times a month across Loudoun County, including Leesburg Chimney Cap & Crown work.
Custom Cap Fabrication
When the flue size or chimney top configuration does not match a standard cap, a custom cap is the only correct solution. Older Ashburn chimneys, especially those on brick ramblers and split-levels from the 1970s and 1980s, frequently have non-standard flue dimensions. We also handle Chimney Cap & Crown - Sterling projects with similar needs. We measure, order, and install custom caps built to spec, often from Copperfield or Olympia Chimney. You receive the exact dimensions in writing before we order anything, and the installation is documented with photos before, during, and after.

Brands We Service for Chimney Cap & Crown
Our crews work on caps and crowns across every major brand, and we stock components from the manufacturers that Northern Virginia chimney professionals respect most. We install and service Copperfield caps regularly, which are known for their heavy-gauge stainless steel construction and tight mesh that keeps even the smallest birds out. We also work extensively with Famco caps, a brand common on older homes, where replacement mesh or frame repairs are often needed.
For crowns and custom fabrication, we source Olympia Chimney materials through the Haven buying network, which keeps our material costs reasonable and our prices to Ashburn homeowners steady. Whether your existing equipment is Copperfield, Famco, Olympia, or any other make, our technicians can service it. What matters is the flue dimensions, the crown condition, and the draft, and we evaluate all three before recommending anything.
BeforeAfterSigns You Need Chimney Cap & Crown Right Now
- Water in the firebox after rain. If you see puddles in your fireplace after a storm, your cap and crown are not doing their job. Water entering the firebox is the result, but the cause is almost always at the top of the chimney. This needs a camera inspection now, because wet fireboxes corrode dampers and rust fireplace components fast.
- You hear animals inside the chimney. Squirrels or birds in the flue are not a fluke. They entered through a missing or damaged cap. Beyond the noise, their nests are a chimney fire risk and can block the flue entirely.
- Visible rust on the cap from ground level. Rust means the metal is already compromised. It will get worse, and patching rusted cap surfaces is rarely worth it. A replacement, sized and installed correctly, is the honest fix.
- Cracks you can see in the crown from the ground or roof. Those cracks are water highways. In Ashburn’s freeze-thaw climate, every winter cycle widens them. Crown cracks never self-heal.
- Your last chimney inspection recommended cap or crown work. If you have a report that mentions crown spalling, cracked mortar, or a missing cap, that work does not get safer with time. The failure mode is water and fire risk, and both are cumulative.
If any of these sound familiar, call (240) 220-9412. We will send a named technician to your Ashburn home, photograph what we find, and show you the evidence on the spot.
Our Chimney Cap & Crown Process - Step by Step

You call and speak to a person. No voicemail trees, no web forms. A live person answers 24/7. You describe what is happening, and we book a time that works for you, with a text when the technician is on the way.
- 2
Camera-scan inspection and roof-level assessment. The technician arrives, checks the flue from the top and bottom, and puts a camera down the chimney to document liner condition, crown condition, and cap condition. This is NFPA 211 Level 2 inspection standard, and it has been our default since 2009.
- 3
Written price, written scope, written warranty. Before any work starts, you get a written document that shows exactly what we found, what we recommend, what it costs, and what is covered after. Haven Standard Clause 1 requires it, and you should never accept less from any chimney company.

The work is performed. Whether it is a crown coat, a cap replacement, or a full crown rebuild, our uniformed, background-checked technicians do the job to spec. You know who is on your roof, and you know what they are doing because it is written down.

Documented photo record on completion. Under Haven Standard Clause 4, every job ends with photos of the completed work. You walk away with an archive you can keep, not a handshake and a promise.
How Much Does Chimney Cap & Crown Cost in Ashburn?
A typical chimney cap replacement in Ashburn runs $350-$800 depending on cap size, material, and whether it is a standard or custom fit, as detailed in our Chimney Cap & Crown cost guide. Crown coating on a standard single-flue chimney usually lands between $250 and $500. Full crown repairs and rebuilds, where the old crown is removed and re-poured, range from $800 to $1,800 depending on access and chimney height. Multi-flue and custom cap projects run higher because of measurement, fabrication, and installation time.
What affects the price:
- Roof pitch and chimney height; steep or tall roofs cost more in labor time.
- Flue dimensions; non-standard openings require custom caps.
- Crown condition; minor cracking can be coated, but spalling or structural damage requires rebuild materials.
- Number of flues; multi-flue caps and crown work across two flues cost more than single-flue jobs.
How to avoid overpaying in Ashburn: get the price in writing before work starts, ask for photos of the problem, and never accept an estimate that does not specify cap size, material, and warranty term. We provide all of that on every job, no exceptions. Your free estimate includes the full written scope, and the price we quote is the price you pay. Call (240) 220-9412 to book one.

Frequently Asked Questions - Chimney Cap & Crown in Ashburn
A chimney crown is the sloped concrete or mortar top that seals the chimney around the flue, and a chimney cap is the metal cover that sits over the flue opening. The crown sheds water, and the cap keeps out animals and debris while allowing smoke to vent. Both sit at the highest point of your chimney and take direct weather exposure all year. When either fails, water and animals get inside the system.
Most cap installations, cap replacements, and crown coating jobs are completed in a single visit lasting two to four hours. Full crown rebuilds may take a half day or longer, depending on curing time and roof access. We give you a written time estimate before we begin, so you know what to expect. The work itself is not disruptive; you may not even notice we are here until the photo report arrives.
Cap replacement runs $350-$800, crown coating $250-$500, and full crown repairs or rebuilds $800-$1,800 in Ashburn.
