Fast, Reliable Chimney Cap & Crown Across Annandale
A properly fitted chimney cap and sound crown in Annandale typically runs $280-$890 depending on whether we’re sealing a hairline crack or fabricating a multi-flue cap for a oversized colonial flue. Most of our Annandale customers get same-week scheduling, and our technicians carry the common Gelco and Olympia Chimney cap sizes on the truck for homes along Braddock Road and Little River Turnpike.
We’ve been driving to Annandale since 1984, back when Fairfax County’s building boom was still fresh and those brick split-levels were new. Forty-two years later, we’re still the ones homeowners call when they spot water stains on the ceiling below the hearth or hear squirrels scrambling in the flue. You can reach us at (844) 803-1545. A live person answers, 24 hours a day.
Why Hearthstone Chimney Co. Is Annandale’s Preferred Chimney Cap & Crown Company
Annandale’s housing stock is our specialty. The post-war brick colonials and split-levels that line the neighborhoods between Braddock Road and Little River Turnpike were built with generous masonry chimneys, but the original caps and crowns are now sixty to seventy years old. We’ve replaced hundreds of them. We know which homes in the 22003 ZIP have the oversized flues that require custom-fabricated caps, and we know which ones still have the mid-century furnace tie-ins that complicate every repair.
Our reputation here is built on showing up when we say we will and leaving the job finished. The 90-Day Done Right Promise governs every cap and crown we install in Annandale: if it’s not right, we make it right, in writing, with no paperwork and no arguing. Our Level-2 camera inspections end with photos you can see and a plain-English verdict, so you understand exactly why your crown is spalling or your cap is failing before we quote a dollar.
Calls to (844) 803-1545 are answered by a live person, not a menu tree. Our background-checked, uniformed technicians complete most chimney cap and crown jobs in a single visit, with no-hassle upfront pricing. The number on the estimate is the number on the invoice.
Our Chimney Cap & Crown Services in Annandale
Chimney Cap Installation
New cap installation in Annandale’s 22003 neighborhoods often means solving a sizing problem. Those original masonry flues from the 1960s and 1970s are frequently larger than modern stock caps cover, especially on homes near Annandale High School where the colonial revival builds clustered. We fabricate and install custom stainless steel and copper caps from Gelco and Olympia Chimney that fit properly, with correct mesh screening to keep out the squirrels and starlings that are active year-round in Fairfax County’s mature tree canopy. A standard single-flue cap installation in Annandale runs $280-$450. Custom or oversized caps range $480-$720.
Chimney Cap Replacement
Cap replacement is our most common call from Annandale homeowners, and there’s usually a story behind it. The original cap blew off in a March windstorm, or it rusted through after twenty years, or a previous owner installed the wrong size and water’s been getting in ever since. We remove the failed unit, inspect the flue and crown beneath it for hidden damage, and install a replacement that matches your chimney’s actual dimensions. Because our Chimney Cap & Crown team stocks common sizes, most Annandale replacements are done in under two hours. Replacement pricing starts at $250 for straightforward swaps and runs to $580 when we need to address underlying crown deterioration.
Crown Repair
The crown is the concrete or mortar wash that seals the top of your chimney, and on Annandale’s mid-century brick homes it’s often the first thing to fail. Our Northern Virginia winters deliver 50-70 freeze-thaw cycles annually, and that expansion and contraction cracks the soft-brick crowns common to this era. Water gets in, freezes, and pries the crown apart from the inside. We repair minor crown damage with professional-grade crown coating materials, rebuilding the slope and seal so water sheds properly. More extensive deterioration requires partial or full crown reconstruction. Crown repair in Annandale typically costs $350-$650. Full rebuilds run $720-$1,100 for standard-sized chimneys.
Crown Coating
Crown coating is preventive maintenance that extends the life of a sound but aging crown, and it’s particularly valuable in Annandale’s climate. Summer humidity along this inland Fairfax County corridor promotes moss and algae growth on north-facing chimney crowns, which holds moisture against the surface and accelerates deterioration. A proper crown coating with HeatShield or similar professional-grade material seals existing micro-cracks, restores positive drainage, and provides a barrier against that biological growth. We recommend crown coating every 8-12 years for Annandale homes with original mid-century chimneys. The service runs $320-$480 and takes about three hours.

Trusted Brands We Service in Annandale
We don’t use builder-grade substitutes. Our Annandale cap and crown jobs are built with professional-grade materials from Famco, Gelco, and Olympia Chimney, brands that have proven themselves through decades of freeze-thaw cycling in climates like ours. We stock common cap sizes and crown coating materials locally, which means faster turnaround for Annandale homeowners and no waiting on special orders for most jobs. When we do need to fabricate a custom cap for one of those oversized colonial flues near Braddock Road, we work with the same suppliers we’ve used since the 1980s. Done right, and we stand behind it.
Common Chimney Cap & Crown Problems We See in Annandale Homes
- Spalling brick and crumbling mortar from freeze-thaw damage. Annandale’s 50-70 annual freeze-thaw cycles attack the soft brick and aging mortar joints on mid-century chimneys. Water enters through cap gaps or crown cracks, freezes overnight, and fractures the masonry. We see this most on homes built between 1955 and 1975 that still have their original crowns.
- Improperly sized or missing caps on oversized flues. The colonial and split-level homes that dominate Annandale’s 22003 ZIP were built with flue dimensions that exceed modern stock cap sizes. A too-small cap leaves gaps where water and animals enter; no cap at all invites squirrels, raccoons, and nesting birds directly into the flue.
- Crown slope failure causing ponding and infiltration. Original crowns on Annandale’s post-war homes were often poured flat or with inadequate overhang. Water ponds on the surface, finds its way through micro-cracks, and rots the framing beneath the hearth. North-facing crowns with moss accumulation deteriorate fastest.
- Hidden damage from decades of mixed-fuel use. In Annandale’s older neighborhoods, it’s common to find chimneys where the original contractor ran both fireplace and furnace exhaust through the same clay liner. That mid-century shortcut, now a code violation under Fairfax County standards, leaves acidic condensate eating the mortar joints beneath the crown. Our Level-2 inspections catch this before we install any new cap.

Annandale pricing is comparable to Burke and Arlington, though homes here often need custom cap sizing for those oversized mid-century flues, which can add $150-$270 to a standard installation. Oakton and Reston have more newer construction with smaller, standardized flues, so their typical cap jobs run at the lower end of our ranges.
