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.

If you live in a Reston cluster townhome, a condo near Lake Anne, or a single-family off Wiehle Avenue, you know the chimneys here aren’t like other Northern Virginia chimneys. The Reston Association’s Architectural Review Board adds a step to exterior work that most companies don’t account for. We do. We’ve coordinated ARB submissions for chase cover replacements, cap installations, and full masonry rebuilds across Reston’s villages. That experience matters when a failed flashing is letting water into your chase in February and the freeze-thaw cycle is actively spalling your brick face.
This page covers Chimney Repair pricing, timing, and local requirements for Reston homeowners. What follows is specific to Reston’s housing stock, climate, and review board process. Not Northern Virginia in general. Reston.
Why Level Two Chimney Ashburn Is Reston’s Preferred Chimney Repair Company
We’ve built our reputation in Reston by doing something most chimney companies don’t do: we document everything with a camera before we recommend anything. Clause 4 of the Haven Standard, which we’ve followed since 2009 and now governs every job we complete, requires a photo record on every visit. When we tell you your flue liner is cracked, you’re looking at the crack on your phone. When we say your mortar joints are failing, you see the missing mortar. You don’t take our word for it. You take the evidence.
Reston homeowners repeatedly call us for three reasons. First, the written price comes before any work starts. No “we’ll let you know after we open it up.” Clause 1 of the Haven Standard says the scope, the price, and the warranty are in writing before our tech arrives. You compare. You decide. Second, our 365-Day Done Right Promise backs every job we complete. If something isn’t right, our team makes it right, period. Third, you’ll talk to a live person when you call. Twenty-four hours a day, seven days a week. Not a voicemail. Not a form. A person at (240) 220-9412.
Led by Corrine Halstead, our team knows Reston’s specific repair patterns from the ground level: the shared chases in cluster townhome sections, the ARB process for exterior modifications, and the early-generation prefabricated fireboxes that look fine from the living room but have failed dampers and compromised smoke chambers behind the face. We don’t just serve Reston. We understand its buildings.
Our Chimney Repair Services in Reston
Mortar Repointing
Repointing replaces the deteriorated mortar between your chimney’s bricks. In Reston, the dominant cause is freeze-thaw cycling: Northern Virginia’s winters cross the freezing point dozens of times per season, and water that enters micro-cracks expands when it freezes, pushing mortar out in small chunks. Homes in Hunters Woods and South Lakes built during the 1960s and 1970s expansions are at the highest risk because their original mortar has had 50 to 60 years of this punishment. Repointing in Reston typically runs $12-$25 per square foot of brick face, with most jobs landing between $500 and $1,500 depending on the chase height and access. Skipping repointing is the fastest way to let water behind the brick, which then spalls the face brick and turns a repointing job into a full rebuild.
Spalling Brick Repair
Spalling is when the face of a brick pops off, leaving a recessed, flaky surface behind. In Reston’s cluster townhome sections, spalling on shared chases affects multiple units, not just yours. We regularly find that one exterior masonry chase on a Reston cluster townhome contains two or three separate terracotta flues serving different units. Water that penetrates the shared brick face migrates into every flue in the chase. A repair that patches only your side of the wall leaves your neighbor’s flue lining exposed to the same moisture. Spalling brick repair in Reston averages $800-$2,400, and the longer it’s deferred, the more brick needs to come out and be replaced.
Chimney Waterproofing
Waterproofing is a silicate-based penetrating sealant applied to the exterior masonry. Unlike paint or sealant films, silane and siloxane treatments let water vapor escape from the brick while preventing liquid water from entering. In Reston, waterproofing matters more than in dryer parts of the state because the region’s icy, wet winters drive water deep into existing micro-cracks before temperatures drop. A proper waterproofing on a two-story Reston chimney runs $450-$900 and takes about a day. We apply it only after repointing and crack repair are complete, because sealing over gaps just traps water inside the masonry.
Flashing Repair
Flashing is the metal barrier where the chimney meets the roofline. In Reston, failed flashing is the most common cause of chimney leaks, and we see it year-round, not just after storms. The freeze-thaw cycles lift the flashing edges away from the masonry, and once the seal is broken, water gets in. Flashing repair in Reston runs $350-$850 depending on whether we’re replacing a section or the entire surrounding system. If you’re seeing water stains on the ceiling near your chimney, the flashing is the first thing we inspect. Corrine Halstead and her team replace flashing with materials sourced through Haven’s buying network, including Olympia Chimney, Famco, and Copperfield, which keeps the price honest without sacrificing quality.

BeforeAfterTrusted Brands We Service in Reston
When your chimney repair requires parts, we source from manufacturers with proven records in Northern Virginia’s climate. Our team works with Olympia Chimney and Famco for caps and dampers, Copperfield for flashing and termination equipment, and DuraFlex for stainless steel and aluminum flue liners. Because we order through Haven’s buying network, Reston customers pay a fair price for real parts, not whatever is left on a home center shelf. We keep common components stocked locally for Reston jobs, which means less waiting when a chase cover needs replacing in the middle of ARB review season. When a spec sheet or part match matters, you’ll see the documentation, not just our word.
Common Chimney Repair Problems We See in Reston Homes
- Shared masonry chases in cluster townhomes. In Reston’s cluster sections, one exterior masonry chase frequently houses two or three terracotta flues serving different units. A blockage or creosote buildup in one flue can backdraft into a neighbor’s system, which means the repair scope expands from one unit to the entire chase. We coordinate access and billing across multiple Reston Association-governed homeowners before work can begin, a step most chimney companies skip.
- ARB approval delays on exterior components. Reston’s Architectural Review Board requires homeowner approval for exterior modifications, including chimney caps and chase covers. If a cap fails in January, the ARB review process can add weeks to the repair timeline. We prepare the submission package, document the failure with photos, and coordinate the filing so your repair isn’t stalled longer than necessary.
- Early-generation prefabricated fireboxes. Many Reston townhomes built in the 1970s through 1980s retain their original factory-built fireplaces. The firebox looks fine from the living room. The smoke chamber and damper, which are inside the chase and invisible without a camera, are often the first components to fail. A Level 2 inspection on a 40-year-old prefab fireplace reveals issues that a visual check from the hearth misses completely.
- Crown cracking from freeze-thaw cycles. Reston’s winters oscillate around freezing dozens of times per season. Water saturates the crown’s hairline cracks, freezes, and widens them. Within three to five years, a cracked crown becomes a channel for water into the masonry. We replace crowns in Reston with a proper overhang and drip edge, not just a cosmetic patch.

FAQs - Chimney Repair in Reston
The Reston Association’s Architectural Review Board requires approval before exterior modifications, including chimney caps, chase covers, and any visible masonry changes. What this means for your chimney repair timeline: if a cap fails and water is getting in, we can’t just swap it out the same day. The ARB submission adds days to weeks depending on the review cycle and whether your application is complete when filed. We prepare the ARB submission package with photos and a written description of the repair scope, so the board gets what it needs without back-and-forth delays. The inspection itself doesn’t require ARB approval, only the exterior work. If you’re facing an active water intrusion, call us at (240) 220-9412 and we’ll document the failure first, then start the ARB process while you decide on the repair scope.
Your 1980s prefabricated fireplace has a metal flue, a smoke chamber, and a damper that are all hidden inside the chase, and all of them are now 40 to 45 years old. The outside and the firebox face look fine because firebrick and metal fronts don’t show internal corrosion. A Level 2 camera scan goes down the flue, into the smoke chamber, and across the damper to document what’s actually there: cracked flue tiles, rusted damper frames, and creosote accumulation that a visual check misses. Corinne Halstead’s team has run 38,000+ camera-scan inspections since 2009 under Haven Standard Clause 4, and the photo record is included on every visit. If your fireplace hasn’t been scanned in the last three years, call (240) 220-9412 to schedule one.
Yes, and we see this in Reston’s cluster townhome sections more than anywhere else in our service area. When one exterior masonry chase contains two or three terracotta flues serving different units, a raccoon nest or heavy creosote deposit in your neighbor’s flue can depressurize the chase and push exhaust gases into your living space. Draft reversal doesn’t respect property lines. The fix requires coordinated access across multiple units, and we manage that coordination with the Reston Association-governed homeowners so the repair isn’t incomplete. In Reston’s Hunters Woods cluster, our tech once found a third-degree creosote tar glaze inside a 1970s prefabricated metal flue that had caused draft reversal into a neighboring unit. We removed the damaged flue liner, installed a new DuraFlex liner, and replaced the rusted chase cover with a Galco cap, then coordinated with the Reston Association to have the shared masonry chase inspected for spalling and repointed before winter freeze-thaw cycles could worsen the brick face. If you smell smoke when your neighbor uses their fireplace, call us at (240) 220-9412.
Freeze-thaw cycling. Reston’s winters cross the freezing point dozens of times per season, and every time water enters a small crack in your crown and then freezes, it expands and widens that crack. What was a hairline fissure in November becomes a quarter-inch gap by March. If your crown is made from a poor mix or lacks a proper overhang and drip edge, the cracking repeats every few years. We replace crowns in Reston with a proper slope, overhang, and drip edge as part of the repair, which stops water from running down the brick face. A crown replacement in Reston typically runs $700-$1,400. Call (240) 220-9412 for a written estimate before the next freeze.
The answer comes from the camera scan and the structural assessment, not a guess from the ground. If the bricks are sound and only the mortar joints are failing, tuckpointing is the fix. If the bricks themselves are spalling, cracked through, or the chase is leaning, the repair is a partial or full rebuild. In Reston’s shared chases, that assessment impacts multiple units, not just your side of the wall, so we document the entire chase condition. You get the photos and the written recommendation, and the decision is yours. A rebuild is never recommended without camera evidence you can see for yourself. Corrine Halstead and her team have completed over 38,000 chimney inspections since 2009, and the documentation practice is written into Haven Standard Clause 4. Call (240) 220-9412 for a Level 2 camera inspection on your chimney.
