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.

AfterFast, Reliable Chimney Cap & Crown Across Arlington
Chimney cap and crown repair in Arlington typically runs $340-$890 depending on whether you need a cap replacement, crown coating, or full rebuild, and most jobs are completed in a single visit with our crew already working across the county. We answer calls with a live person 24 hours a day at (571) 489-4365, and our technicians are background-checked, uniformed, and carry the professional-grade materials to finish the job on arrival.
Arlington’s housing stock is unlike anywhere else in Northern Virginia. Thousands of brick cape cods and ramblers in Ashton Heights, Westover, Lyon Village, and Dominion Hills were thrown up fast for wartime federal workers in the 1940s, built with soft lime mortar and clay tile flues sized for coal furnaces, not the wood-burning fireplaces owners use today. Our Chimney Cap & Crown team knows these chimneys. We’ve spent 42 years diagnosing why they leak, why they smoke, and why a quick cap swap isn’t always the right fix.
Dispatch and scheduling are coordinated from our Washington, DC office, but crews serve Arlington locally every day. We know the difference between a Dominion Hills rambler with a prefab metal chase and a Westover cape cod with original masonry that hasn’t been touched since Truman was president. That matters when you’re deciding whether a crown needs coating or rebuilding, or whether your flue is even the right size for the appliance venting into it.
Why Hearthstone Chimney Co. Is Arlington’s Preferred Chimney Cap & Crown Company
We’ve been answering the phone with a live person for over 42 years, and that hasn’t changed. Arlington homeowners call us because they’ve dealt with contractors who disappear, or worse, contractors who recommend $4,000 in “urgent” work without showing them a single photo of the problem. We don’t work that way.
Our Level-2 camera inspections end with photos you can see and a plain-English verdict. No camera evidence, no recommendation. That’s our rule, and it protects homeowners in neighborhoods like Lyon Village and Ashton Heights, where unlined clay flues and deteriorated crowns are common but not always catastrophic. The 90-Day Done Right Promise backs every job in writing - if it’s not right, we come back, no arguing, no paperwork games.
Most cap and crown jobs in Arlington are completed in a single visit because our trucks stock DuraFlex, HeatShield, Gelco, and Olympia Chimney materials. No waiting for parts. No return trips. The number on your estimate is the number on your invoice.
We also know Arlington’s specific failure patterns. The 15-25 freeze-thaw cycles each winter spall 1940s lime mortar in crown joints faster than in drier inland Virginia markets. Summer humidity wicks into unlined clay flues so interior tile cracks by the time the first fall fires are lit. A sweep who doesn’t know Arlington’s climate and housing stock might miss that entirely. We don’t.
Our Chimney Cap & Crown Services in Arlington
Crown Repair
Arlington’s original 1940s lime-mortar crowns in Ashton Heights and Westover spall and crack through repeated freeze-thaw, letting meltwater drip down into the smoke chamber and erode flue tile joints from the inside. Crown repair isn’t always a full rebuild. If the structural concrete is sound but the surface is cracked and porous, we can coat it with HeatShield crown repair - a professional-grade refractory compound that seals the surface and sheds water with a proper overhang and drip edge. If the crown has lost its flaunching or the concrete is compromised, we rebuild it. Either way, you see the camera footage before we recommend either path.
Crown Coating
For Arlington chimneys where the crown is structurally intact but weathered, crown coating is the square deal - stops water intrusion without the cost of full demolition. We see this often in Lyon Village and Dominion Hills, where owners have maintained their chimneys reasonably well but the soft original mortar is finally giving out after eight decades. HeatShield crown coating goes on at proper thickness, not the thin wash some operators slap on. It carries our 90-Day Done Right Promise same as a rebuild. Photos first, then the recommendation, then the fix.
Cap Installation & Cap Replacement
A missing or rusted cap is an open invitation to rain, squirrels, and the summer humidity that accelerates interior tile cracking in Arlington’s unlined clay flues. We install and replace caps with Gelco stainless steel mesh screens and proper fit for your flue size - not the big-box adjustable caps that leave gaps. In Dominion Hills, we routinely replace single-flue caps that were never right for multi-flue chimneys, leaving the second flue exposed. Our caps come with no-hassle upfront pricing and are backed in writing.
Multi-Flue Cap & Custom Cap
Many Arlington cape cods and ramblers have multiple flues - one for the fireplace, one for the furnace or water heater - and a single-flue cap leaves the other open to weather and wildlife. We install custom multi-flue caps measured to your chimney’s exact dimensions, with stainless mesh from Olympia Chimney and Famco hardware. For non-standard chimney profiles or chase pans on prefab units in newer Arlington townhouse clusters, we fabricate custom caps that fit properly and shed water. No gaps. No rust-through in three seasons. Done right, and we stand behind it.

Trusted Brands We Service in Arlington
We work exclusively with professional-grade materials - no builder-grade substitutes. For Arlington’s cap and crown work, we stock HeatShield for crown coating and repair, Gelco stainless steel caps and mesh, and Olympia Chimney and Famco components for multi-flue and custom installations. These are the brands specified by sweeps who plan to be in business thirty years from now, not the disposable hardware that box stores move by the pallet. Our trucks carry inventory for most common Arlington chimney profiles, so we’re not ordering parts while your chimney takes on water.
Common Chimney Cap & Crown Problems We See in Arlington Homes
- Spalled crown joints from freeze-thaw damage. Arlington’s 15-25 annual freeze-thaw cycles destroy the soft 1940s lime mortar in chimney crowns, especially in Ashton Heights and Westover. Meltwater enters hairline cracks, freezes, expands, and opens the joint wider each cycle. By spring, the crown is shedding chunks and water is running down the flue walls.
- Wrong-size flue tiles in postwar add-on fireplaces. In Westover and Lyon Village, we regularly find fireplaces that were added to chimneys originally built for coal furnace flues. The clay tile is too large for wood-burning, draft is chronically poor, and first-degree creosote accumulates fast. A proper cap can’t fix draft, but it can keep rain from compounding the problem while we diagnose the flue sizing.
- Single-flue caps on multi-flue chimneys. Homeowners in Dominion Hills and Lyon Village often inherit a cap that covers only the fireplace flue, leaving the furnace or water heater flue open to rain and squirrels. We replace these with properly sized multi-flue caps that protect every penetration.
- Original crowns with no drip edge or overhang. Many 1940s Arlington chimneys were finished with a simple mortar wash that sheds water poorly and offers no protection to the brick below. We rebuild with proper crown geometry - minimum 2-inch overhang, drip edge, and positive slope - or coat existing sound crowns to achieve the same protection.
Pricing for Chimney Cap & Crown in Arlington, VA
Here’s what cap and crown work actually costs in Arlington’s market. These are the ranges we quote after inspection, not bait-and-switch numbers that balloon on the invoice.
| Service | Typical Range in Arlington |
|---|---|
| Standard cap replacement (single flue) | $340-$520 |
| Multi-flue cap installation | $580-$890 |

What moves the number? Accessibility (steep roof pitches common in Ashton Heights and Westover add time), the condition of the existing crown substrate, and whether we find flue damage that needs addressing before capping. We don’t upsell. If coating will last, we say so. If the crown is too far gone, we show you why on camera. Estimates are free. Call (571) 489-4365 for an exact quote.

FAQs - Chimney Cap & Crown in Arlington
It depends on whether the structural concrete beneath the mortar is sound. If the crown still has integrity and the damage is surface cracking and spalling, HeatShield crown coating is often the right fix at roughly half the cost of rebuilding. If the concrete is cracked through, flaunching is washed out, or water has reached the smoke chamber, rebuilding is the only durable option. We determine this with a Level-2 camera inspection - you’ll see the footage before we recommend either path. Call (571) 489-4365 for a free estimate.
Smoking back into the room usually indicates a draft problem, and in Westover’s postwar cape cods, the most common cause is a flue tile sized for a coal furnace, not a wood-burning fireplace. The flue is too large for the fireplace opening, so smoke cools and sinks before it rises. A chimney cap with proper mesh and overhang won’t fix draft, but it can keep rain from worsening creosote buildup while we diagnose whether relining or a smoke guard is the real solution. We never recommend cap work alone for a smoking fireplace without camera-verifying the flue size first. Call (571) 489-4365 to schedule.
If your flue is standard size and the chimney has a single flue, a stock Gelco stainless replacement cap is usually sufficient. If the chimney has multiple flues, an unusual profile, or a prefab chase pan that’s integrated with the cap, a custom fabrication is often the better long-term value. We measure on site and quote both options when applicable. No surprises on the bill. Call (571) 489-4365 for pricing.
Yes - more than in drier inland Virginia markets. Arlington’s 15-25 annual freeze-thaw cycles, combined with soft 1940s lime mortar, cause aggressive spalling and joint failure. Water enters micro-cracks, expands 9% when it freezes, and opens the crack wider each cycle. A crown that looks sound in October can be shedding chunks by April. Annual inspection catches this before water reaches the flue interior. Call (571) 489-4365 to book.
Before burning, you need a Level-2 inspection to verify the clay tile condition, flue size compatibility with your stove’s BTU output, and whether the crown and cap are keeping water out of the flue. Summer humidity in Arlington wicks into unlined clay and accelerates interior cracking; by fall, cracked tiles can leak combustion gases or allow creosote to build in wall cavities. We document everything with photos and give you a plain-English verdict on whether the flue is safe for wood stove use, needs relining, or just needs a proper cap and crown repair. Call (571) 489-4365 to schedule before your first fire.
