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.

We’ve been working on McLean chimneys for decades. The houses here are different from what you’ll find in Falls Church or Arlington - larger lots, multiple masonry fireplaces, original clay-tile liners from the 1970s and 1980s that are now well past their prime. Whether you’re off Georgetown Pike, in the Langley area, or closer to Chesterbrook, we know the housing stock and we know what fails on it. Our technicians carry the right materials to fix it on the first trip.
Why Hearthstone Chimney Co. Is McLean’s Preferred Chimney Cap & Crown Company
McLean homeowners tend to stay put. They’ve lived in the same colonial or Georgian for twenty, thirty, sometimes forty years. They’ve also been burned by a contractor who talked a good game and left a mess. We understand that. Our reputation here was built one job at a time - documented with photos, priced upfront, and backed by the 90-Day Done Right Promise in writing. If it’s not right, we come back. No arguing, no paperwork chase.
Our Level-2 camera inspections end with photos you can see and a plain-English verdict. In McLean, where many homes have two or more fireplaces, that documentation matters. You’ll know which flue needs attention now, which can wait, and why. No surprises on the bill - the number on the estimate is the number on the invoice.
A live person answers our phones 24 hours a day, 7 days a week. Not a voicemail, not a callback queue. When you call (571) 489-4365, someone picks up. Our background-checked, uniformed technicians complete most jobs in a single visit, and scheduling is coordinated from our Washington, DC office with crews serving McLean locally.
Our Chimney Cap & Crown Services in McLean
Cap Installation
New cap installation in McLean runs $280-$520 for a standard single-flue stainless steel unit, with custom or multi-flue caps running higher depending on flue count and dimensions. Many of the 1960s-1990s brick colonials in the Chesterbrook area were built with bare flue openings or deteriorated original caps that have long since rusted through. We measure on site and fabricate to fit - no builder-grade substitutes. Our caps are sourced from Gelco and Olympia Chimney, brands we’ve trusted for years.
Cap Replacement
Cap replacement in McLean is one of our most common calls, and it usually tells a story. The old cap is rusted, wind-damaged, or - especially along Georgetown Pike - packed solid with oak and maple leaves that trapped moisture against the crown until something gave way. Replacement typically costs $240-$480. We remove the failed unit, inspect the crown and flue tile beneath it, and install a proper-fitting replacement with correct clearance and spark screening. If the crown is compromised, we’ll show you the photo and explain your options before doing anything.
Crown Repair & Crown Coating
Crown repair and coating is where McLean’s climate really shows up in our work. Northern Virginia’s freeze-thaw cycling from November through March - temperatures crossing 32°F multiple times per week - aggressively spalls the mortar crowns on exposed masonry chimneys. A cracked crown lets water track straight down into the smoke chamber and firebox.
Crown coating with HeatShield, a professional-grade refractory compound, runs $420-$680 for a typical McLean chimney and can add years of service life to a sound but weathered crown. If the crown is too far gone, we’ll say so plainly and discuss rebuild options. We don’t coat a crown that needs rebuilding, and we don’t push a rebuild when coating will do the job.
Multi-Flue & Custom Caps
Multi-flue caps are essential for McLean’s larger homes with multiple fireplaces sharing a chimney structure. A proper multi-flue cap covers all flues with correct clearance, preventing cross-drafting and keeping debris and animals out of every opening. Custom caps, fabricated for non-standard chimney profiles or estate homes with architectural requirements, run $680-$1,400 depending on material and complexity.
In the teardown zones where mid-century ranchers have been replaced by 6,000+ square foot custom builds, we also find complex multi-flue systems that need custom solutions. And in older holdover homes, we regularly discover decommissioned flues inside new construction that were never properly capped or sealed - a detail that gets missed until water shows up somewhere it shouldn’t.
In the Langley area, a 1980s colonial with two masonry fireplaces was getting water into the lower firebox after every storm. The upper flue’s chimney cap was packed with oak leaves and its crown had spalling mortar and a hairline crack; we installed a custom multi-flue cap and coated the crown, and the damper stayed dry through the next freeze-thaw cycle.

Common Chimney Cap & Crown Problems We See in McLean Homes
- Leaf-packed caps along the Georgetown Pike canopy - McLean’s dense mature hardwood canopy fills chimney caps with debris quickly each fall. Clogged caps back up draft, trap moisture against the crown and spark screen, and create the conditions for accelerated corrosion and water intrusion.
- Freeze-thaw crown spalling on 1970s-1990s masonry - Original chimney crowns from McLean’s building boom decades are now failing under Northern Virginia’s aggressive winter cycling. Hairline cracks widen, mortar spalls, and water finds its way to the smoke chamber and firebox below.
- Animal nesting in infrequently used flues - Squirrel and raccoon nesting is one of our most common call types in the older Langley and Chesterbrook neighborhoods. Technicians almost routinely pull animal nests before inspection. Nesting dislodges caps, blocks flue liners, and creates fire and carbon monoxide hazards - often discovered only at a Level 2 inspection.
- Decommissioned flues in teardown-and-rebuild construction - Ongoing teardown activity means we regularly find flues that were abandoned during renovation but never properly capped or sealed. An open flue is an open path for water, animals, and conditioned air loss.

FAQs - Chimney Cap & Crown in McLean
Yes. Homes with two or more masonry fireplaces sharing a chimney structure need a multi-flue cap that covers all flues with correct clearance, or individual properly-sized caps for each flue. McLean’s large colonials and estate homes often have upper and lower fireplaces where a failure on one flue can send water into the system below. We measure every opening and specify caps that prevent cross-drafting and keep all flues protected. Call (571) 489-4365 to schedule an inspection of your multi-flue system.
Hairline cracks and surface spalling on an otherwise sound crown can usually be coated with HeatShield refractory compound, adding years of service life for $420-$680. If the crown has structural cracks, is separating from the brick, or has deteriorated past a certain point, coating will not work and partial rebuild is the honest recommendation. We photograph the crown during our Level-2 inspection and show you exactly what we’re seeing before suggesting any course of action. Nothing is recommended without camera evidence you can see for yourself.
Every 12 months, per NFPA 211 - regardless of how little you burn. In McLean, where many fireplaces see only occasional “decorative” smoldering fires, this is especially important. Those low-temperature burns produce heavy Stage 2 creosote buildup, and infrequent use means caps fill with leaves and animal nests undisturbed. An annual inspection catches crown cracks, cap failures, and flue blockages before they become water damage or safety hazards. Call (571) 489-4365 to book your inspection.
McLean’s defining mature hardwood canopy - especially dense along and off Georgetown Pike - sheds heavily each fall, and standard mesh screening on chimney caps catches that debris quickly. Homes in the Langley and Chesterbrook areas are particularly prone. The fix is usually a cap with proper spark arrestor design and adequate mesh size, or in some cases a custom cap with debris deflection. We also check that your cap is properly secured; a loose or ill-fitting cap shifts and creates gaps that funnel leaves directly in.
Stage 2 creosote - the flaky, tar-like deposit from slow, low-temperature burns - is the hidden risk in McLean’s rarely used fireplaces. Those “decorative” fires for ambiance, not heat, burn below 250°F and produce this sticky, highly combustible buildup. Stage 2 creosote is harder to remove than light soot and creates a significant chimney fire hazard even in infrequently used systems. A Level-2 inspection with camera documentation tells you what stage you’re at and whether sweeping is needed before the next burning season. Call (571) 489-4365 for a free estimate.
