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.

Call (240) 220-9412 and you’ll get a live person, not a voicemail.
Why Level Two Chimney Ashburn Is McLean’s Preferred Chimney Repair Company
McLean isn’t like other Northern Virginia markets. We regularly service homes in Langley Oaks, Chesterbrook, and along Old Dominion Drive where a single address has four fireplaces across three floors, and each one needs its own inspection. That’s the job we built our process around. Since 2009, our crews have completed more than 38,000 chimney inspections and cleanings, and every single one included a documented photo record before we left the property. No other company in the McLean area can show you that archive, because it’s been our default since day one. Clause 4 of the Haven Standard requires a camera record on every visit. We never treat documentation as an add-on.
Our technicians arrive in uniform, background-checked, with a named tech assigned to your job and a text sent when they’re on the way. You’ll get a written scope, a written price, and a written warranty handed to you before any tools come off the truck. That’s Clause 1 of the Haven Standard. If we recommend a liner replacement, we’ll show you the camera footage that justifies it. If we say the crown is spalling, you’ll see photos of the deteriorating mortar. Our Chimney Repair team does not ask you to take anything on faith.
Our Chimney Repair Services in McLean
Mortar Repointing in McLean
McLean’s original 1950s-1970s brick colonials endure 30-40 freeze-thaw cycles per winter. Water infiltrates hairline cracks in the mortar joints, freezes, expands, and slowly pushes the joints apart. Left alone, the mortar crumbles and the bricks begin to shift. Repointing removes the deteriorated mortar to a consistent depth and replaces it with fresh, color-matched material. In McLean, a typical repointing job on a single exposed chimney runs $350-$700, depending on access and how far up the stack the damage extends.
Spalling Brick Repair
Spalling is what happens when bricks themselves start to flake, crack, and shed faces. We see it most often on the windward side of chimneys in McLean’s older neighborhoods, where decades of rain and freeze-thaw have pushed past the brick’s protective surface. Once a brick spalls, it becomes a direct entry point for water into the chimney structure. Repair means removing and replacing the damaged units. The brick has to match, and on a 1960s Chesterbrook ranch that can mean sourcing reclaimed brick rather than a modern equivalent. Spalling repair in McLean typically ranges from $500-$1,200 depending on how many units are affected.
Chimney Waterproofing
McLean’s housing stock splits into two camps: original brick chimneys that have never been sealed, and new construction where the builder skipped waterproofing entirely. Both fail. A breathable siloxane-based waterproofing treatment stops water absorption while still letting moisture vapor escape from inside the masonry. It’s not paint. It’s a penetrating sealant that our crews apply after repair work is done, and it’s one of the most cost-effective steps you can take to slow freeze-thaw damage. Waterproofing a single chimney in McLean runs $450-$950, and we recommend it on every exposed masonry stack we touch.
Flashing Repair
Flashing is the metal transition where the chimney meets the roofline, and it’s the most common leak point we find in McLean homes. Heavy snow melt in January and February, followed by spring rain, puts constant pressure on aging flashing. When it fails, water runs down the chimney chase, soaks the ceiling joists, and shows up as a brown stain on a bedroom ceiling. We cut out the old flashing, install new step and counter flashing, and seal the joint with a polyurethane caulk rated for masonry. Flashing repair in McLean ranges from $400-$900 for a standard single-flue chimney. Copper flashing on a larger estate home may push toward $1,200.

BeforeAfterTrusted Brands We Service in McLean
We install and repair chimney systems from manufacturers we trust: Gelco for crowns and cap products, Olympia Chimney for stainless liners and termination kits, and Copperfield for caps and chase covers. We stock common parts for these systems regionally, which means a McLean homeowner with a cracked Gelco crown or a wind-damaged Copperfield cap doesn’t wait weeks for a special order. If your home has a different brand installed, we’ll assess it honestly and tell you whether it’s worth repairing or replacing with something better.
Common Chimney Repair Problems We See in McLean Homes
- Freeze-thaw spalling on older exposed brick chimneys. McLean’s 30-40 freeze-thaw cycles per winter are brutal on 1950s-1970s brick stacks. Water gets in, freezes, and bricks start shedding faces. This is the single most common repair call we get in neighborhoods like Langley Oaks and along Dolley Madison Boulevard.
- Multiple fireplaces, undocumented history. McLean’s teardown-and-rebuild cycle means many 6,000-12,000 sq ft homes have three, four, even five fireplaces. High turnover among federal officials and diplomatic staff means new owners often inherit systems with zero service records. We frequently find cracked liners and deteriorating fireboxes on chimneys that were never used.
- Leaf and debris loads from mature oak and tulip poplar canopies. Chesterbrook and parts of McLean’s western edge have heavy tree cover. Every October and November, uncapped flues fill with leaves, twigs, and the occasional squirrel nest. That debris holds moisture against the flue walls and becomes kindling inside the chimney.
- Flashing failures after heavy snow or rain. McLean gets real winters and real spring storms. Old flashing bends, cracks, and pulls away from the masonry. By the time you see a ceiling stain, water has been moving through the chase for weeks.

FAQs - Chimney Repair in McLean
Because McLean gets 30-40 freeze-thaw cycles every single winter, and each one works the mortar joints a little further apart. A 1960s brick chimney that was repointed a decade ago with the wrong mortar mix may already be showing joint deterioration again. The fix is using the right mortar for the brick’s age and hardness, plus waterproofing to slow water absorption. If you’re seeing crumbling mortar or sandy residue at the base of the chimney, call (240) 220-9412 and we’ll put a camera on it to confirm the extent before quoting anything.
You don’t, until someone puts a camera down each flue. McLean’s teardown-rebuild cycle means many estate homes have multiple fireplaces that were installed for aesthetics and rarely, if ever, used. The liner may be cracked, the smoke chamber may be unparged, or the firebox may have hidden spalling. Our Level 2 inspection covers every flue in the home, and you walk away with a photo record of each one. That’s exactly what a new owner in McLean should insist on. Call (240) 220-9412 and we’ll inspect all of them in one visit.
Yes, and it’s not subtle. An uncapped flue under a mature oak canopy in Chesterbrook will fill with leaves, twigs, and acorn debris every fall. That organic material sits on top of the smoke shelf, holds moisture, and restricts draft. We’ve also pulled raccoon and squirrel nests out of flues on homes that sat vacant during an ownership transition, which happens more in McLean than almost anywhere else in Northern Virginia. The fix is a properly sized chimney cap, which we install as part of most repair jobs. Call (240) 220-9412 and we’ll check whether your cap is doing its job.
First-degree creosote is a flaky, soot-like coating that brushes off during a standard sweep. Third-degree creosote is a hard, tar-like glaze that forms when a flue runs cool and wet, often in chimneys that are used occasionally rather than daily. McLean has a real fire season from October through April, and a lot of homes are used for entertaining rather than daily heat, which means those chimneys run at exactly the wrong temperature for creosote to harden. Third-degree creosote requires mechanical removal and sometimes chemical treatment, and it’s a serious fire hazard in any flue where it’s present. If you haven’t had a sweep this year, call (240) 220-9412 and we’ll identify what’s actually in your flue.
You have the chimney swept, inspected, and the damper sealed shut before you leave. Seasonal residents in McLean are common, and we routinely find chimneys in second homes that sat unused for six months with animal nesting, water intrusion, or a failed damper. If you’re leaving before the coldest months, we recommend one visit: a sweep to remove whatever’s accumulated, a camera inspection to confirm the liner and crown are intact, and a top-sealing damper or chimney cap if the existing one isn’t doing its job. You’ll leave with photos of every flue and a written record of the condition. Call (240) 220-9412 to schedule before you go out of town.
