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 Alexandria Homeowners
A damaged chimney cap or cracked crown in Alexandria isn’t something to put off, and our Chimney Cap & Crown in Alexandria service can address it quickly. Rain, snow, and freeze-thaw cycles work into the masonry all winter, and by spring you’re looking at spalling brick, a rusted damper, or water staining on the ceiling near the flue. Level Two Chimney Alexandria has inspected and repaired more than 38,000 chimneys since 2009, and we’ve seen what a failed cap and crown does to a home in this climate. Every job starts with a camera-scan inspection and a written price before any work begins. Call (240) 290-6726 and we’ll tell you exactly what’s happening up there and what it costs to fix.
What Our Chimney Cap & Crown Service Includes
A chimney cap and crown are the two parts of your chimney that keep water out. They work together, and when one fails the other usually follows. Here’s what we handle in Alexandria, and how we approach each piece of the job.
Cap Installation
A cap is the metal or masonry cover at the very top of the flue. It keeps rain, leaves, birds, and nesting squirrels out of the chimney, and a properly sized cap also arrests sparks and embers before they can reach your roof or a neighbor’s. We install caps sized to the flue tile rather than using a one-size-fits-all unit with a universal clamp. The cap gets sealed to the flue crown, and you receive a photo record of the installation before we leave.
Cap Replacement
If your existing cap is rusted through, bent, or was never rated for a wood-burning fireplace, replacement is the fix. We see a lot of galvanized caps on Alexandria rooflines that have rusted out in under a decade. We replace with stainless steel or copper units from Olympia Chimney and Copperfield, built to handle the Mid-Atlantic’s rain and humidity. You’ll see the old cap in photos side by side with the new one, so the difference isn’t something you take on faith.
Crown Repair
The crown is the concrete or mortar slab that caps the chimney structure itself, sloping away from the flue to shed water. When a crown cracks, water gets behind it and freezes, which widens the cracks every winter. Small hairline fractures can be routed and sealed. A crown that’s crumbled at the edges or sagging toward the flue needs to be rebuilt. We’ll show you the camera footage of the crown before quoting the repair, so you can see exactly what we’re seeing.
Crown Coating
For crowns that are structurally sound but showing surface wear, a breathable waterproof coating is often the right call before full repair becomes necessary. We apply a flexible elastomeric coating that moves with the masonry through freeze-thaw cycles instead of cracking against them. It’s not a band-aid; it’s the same treatment we’d put on a new crown to extend its life. The coating is documented in the photo record, and the warranty is written, not verbal.
Multi-Flue Cap
Homes in Alexandria’s older neighborhoods often have two or three flues sharing one chimney chase. A single-flue cap doesn’t work for these; you need a multi-flue unit that spans the crown and covers all flue openings while leaving proper draw clearance. We fabricate multi-flue caps to the exact chase dimensions, including custom widths for historic masonry that isn’t square to modern code. Each flue gets its own screen and spark arrestor, so one blocked flue doesn’t choke the whole chimney.
Custom Cap
Some chimneys in Old Town and Rosemont have flue sizes or chase shapes that no stock cap fits. That’s where a custom cap earns its cost. We measure the flue and crown on site, build the cap to spec in stainless steel or copper, and install it with proper mechanical fastening, not just sealant. Custom caps can also match architectural detail where a visible chimney matters to the look of the home. The price is quoted in writing before we fabricate anything, and the lead time is built into that quote.

Brands We Service for Chimney Cap & Crown
We’re a factory-trained installer for Olympia Chimney and Famco caps. Olympia builds the stainless and copper caps we recommend most often in Alexandria because their mesh gauge and spark arrestor design hold up to both wood smoke and gas flue condensation. Famco’s multi-flue and custom-size units cover the odd dimensions we see weekly in homes built before 1960.
Copperfield caps are the choice when a homeowner wants a cap that will patina over time and match existing copper flashing or gutters. We stock Copperfield components and install them with stainless fasteners so the dissimilar metals don’t corrode at the connection points. DuraFlex is our source for liner-compatible cap collars that join a new flue liner to the cap without cement joints that crack. We’ve serviced thousands of chimneys with these products, and whether you have Olympia, Famco, Copperfield, DuraFlex, or a cap we’ve never seen before that a roofer bolted on, we can tell you what’s working and what’s not.
BeforeAfterSigns You Need Chimney Cap & Crown Right Now
- Water staining on the ceiling or walls near the chimney. Water entering through a failed cap or cracked crown travels down the flue and shows up as brown staining on drywall or plaster. By the time the stain is visible, the water has been getting in for months. The fix starts at the top of the chimney, not with repainting the ceiling.
- Rusted damper or firebox components. A damper that’s rusted open or seized shut tells us water has been coming straight down the flue. The damper rust is usually the first visible symptom; the flue liner above it is often worse. We’ll scope the liner with the camera to see the full picture before recommending anything.
- Spalling brick or crumbling mortar at the top of the chimney. When the crown fails, the top courses of brick absorb water and start to flake, or spall. You may see brick chips in the gutter or on the roof. The crown repair and any brick work need to happen together, or the new crown sits on brick that’s already compromised.
- Birds, squirrels, or nesting material in the chimney. A missing or damaged cap is an open door. We’ve pulled dead birds, squirrel nests, and a full raccoon’s winter den out of Alexandria flues. Beyond the mess and odor, nesting material pressed against a flue liner is a fire risk. A properly installed cap with the right mesh closes that door for good.
- Chunks of mortar on the roof or in the yard after a storm. Crown material doesn’t come off unless it’s failing. If you’re finding small pieces of concrete or mortar after weather, the crown is degrading and water is working into the structure below it. Don’t wait for the next freeze cycle to make it worse.
Our Chimney Cap & Crown Process - Step by Step
Here’s what happens when you call Level Two Chimney Alexandria for a cap or crown job. The process is the same whether it’s a $300 cap replacement or a full crown rebuild.
- 1
Call and schedule. You’ll reach a live person at (240) 290-6726, 24/7. We ask what you’re seeing, whether there’s been visible water or animal activity, and when in the past any work was done. We book a two-hour window and assign a named technician before the day of the job.
- 2
On-site camera inspection. Your technician arrives in uniform, introduces themselves, and sets up. The NFPA 211 Level 2 camera scan runs the full flue, and we photograph the cap and crown from the roof. You’ll see the footage in real time if you want to stand with us, and every image goes into your file.
- 3
Written scope and price. Before anyone touches the chimney, you get a written proposal that names the specific repair, the materials (including brand and gauge where relevant), and the price. No ranges, no verbal estimates, no “we’ll see once we’re in there.” If it’s a crown coating versus a full rebuild, the proposal says which one and why.
- 4
Repair or installation. We do the work the same day in most Alexandria cases. Cap replacements and coatings are quick. Crown rebuilds take a full day including cure time. Your technician documents the repair in progress and after completion; you’ll see the finished crown with the old photos side by side.
- 5
Documented close-out and warranty. Before we leave, you get the written warranty for materials and labor, and the full photo record is sent to you digitally. This is Clause 4 of the Haven Standard, and we’ve done it on every job since 2009. If anything isn’t right, the 365-Day Done Right Promise means we return and make it right.
How Much Does Chimney Cap & Crown Cost in Alexandria?
A typical cap replacement in Alexandria runs $285-$475 depending on flue size and whether it’s a standard single-flue unit or a wider chase, as detailed in our Chimney Cap & Crown cost guide. Cap installation on a chimney that never had one starts around $350 and goes up with flue count. Crown repair for routing and sealing hairline cracks runs $225-$450; a full crown rebuild is $1,200-$2,400 depending on chimney width and access. Crown coating runs $350-$700. Multi-flue and custom caps are quoted per chimney, starting around $650 and ranging up to $1,800 for large custom copper work. Structural repairs with matching brick are extra and priced line by line.
The variables that move the price are flue size, chimney height (which affects equipment setup), roof pitch for access, and whether the existing crown masonry is sound or needs a rebuild first. You avoid overpaying by getting the camera footage and seeing exactly what needs repair before agreeing to anything. Our free estimate includes the Level 2 camera scan, which most Alexandria chimney companies charge separately or skip. If you have a written quote from another company, bring it in, and we’ll give you a free second opinion on it.

Frequently Asked Questions - Chimney Cap & Crown in Alexandria
A chimney cap is the metal cover over the flue opening that keeps rain, animals, and debris out while containing sparks. The crown is the concrete or mortar slab that tops the chimney structure and slopes to shed water away from the flue. Together they form the weatherproof top of your chimney; when either fails, water enters the masonry and flue. We rebuild and replace both, often on the same visit.
Most cap installations or replacements are done in under two hours from setup to photo record. Crown coating is a half-day including cleaning and prep. A full crown rebuild typically runs a full day, sometimes two if the chimney is tall or roofline access requires extra safety setup. We’ll tell you the exact time window in the written quote before work begins.
Cap replacements run $285-$475, cap installations from $350, crown coatings $350-$700, and full crown rebuilds $1,200-$2,400. Custom and multi-flue caps start around $650. Every quote is written and itemized before work starts, so there’s no guesswork. Call (240) 290-6726 for a free estimate with the camera inspection included.
Yes, we install and service Olympia Chimney and Copperfield caps regularly across Alexandria, and we stock Olympia stainless units in common flue sizes. We also work with Famco and DuraFlex components for liners and cap collars. If your cap is a make we don’t recognize, the camera inspection will identify what you have and what will actually fit the flue.
If you have an exposed flue, active water entry during a storm, or animals in the chimney, we’ll try to get a technician to you the same day or next morning. Same-day availability in Alexandria depends on the schedule, and we’ll tell you honestly when the next window is. For a damaged cap that’s still in place, a repair within the week is typically fine. Call (240) 290-6726 and we’ll triage it with you.
Every cap and crown job comes with a written warranty covering materials and labor, and the 365-Day Done Right Promise means if it isn’t right, we return and make it right at no cost. The warranty is in writing with your job file, not a verbal promise. Crown coatings and stainless caps also carry manufacturer warranties we’ll provide at installation.
Clear any items near the fireplace, and if you have a gas log set, turn off the pilot. We’ll handle roof access, including setup on sloped roofs; you don’t need to provide ladders or clear gutters. If you have pets, let us know so we can manage door traffic while moving between the roof and the fireplace. That’s all we need; everything else is on us.
