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 Repair Across McLean
Chimney repair in McLean, VA typically costs between $450 and $3,800 depending on what’s actually wrong, and most jobs take one to two days once we’re on site. That’s the honest range: a flashing patch sits at the low end, a full flue liner replacement or partial rebuild at the top. We inspect first, show you the camera footage, and put a written price in your hand before any work starts. Call (240) 290-6726 to schedule an inspection in McLean, and we’ll be out within the week.
Our crews know McLean’s housing stock well: the tall Colonials off Dolley Madison Boulevard, the brick Tudors tucked into Langley Forest, the contemporaries along Georgetown Pike. These homes were built for multiple fireplaces. When one flue has a problem, the others usually aren’t far behind. That’s why we inspect the whole system on every visit, not just the fireplace you called about.
Why Level Two Chimney Alexandria Is McLean’s Preferred Chimney Repair Company
We’re not the oldest company in the book, and we’re not trying to be. What we do is document everything: photos of the liner, the crown, the smoke chamber, the flashing, all before we recommend a single repair. Since 2009, under the Haven Standard, every job gets a written scope, a written price, and a written warranty before work begins. That’s Clause 1 of the Haven Standard, and it’s not negotiable.
Corrine Halstead, who leads our team, built this company around the inspection standard most sweep companies skip: an NFPA 211 Level 2 camera scan, documented and archived, on every single visit. That means when we tell a McLean homeowner the liner is spalling, they can see exactly what we’re seeing. No flashlight theatrics, no “trust me.” We’ve completed more than 38,000 chimney inspections and cleanings since 2009, and every one ended with a written record.
McLean homeowners call us because we show up on time, the tech’s name is on the page, and the job doesn’t start until the price is in writing. Our phones are answered by a live person around the clock. For the full picture of where we work, see our Chimney Repair in McLean service area details.
Our Chimney Repair Services in McLean
McLean’s housing stock runs large: multiple masonry fireplaces per house, tall flues, and decades of deferred maintenance. These are the four repair categories we handle most often here.
Mortar Repointing
McLean’s winter freeze-thaw cycles chew through mortar joints on exposed chimneys faster than most homeowners expect. Water works into hairline cracks, freezes, expands, and pops the mortar loose. Repointing in McLean typically runs $700 to $1,600 per chimney face depending on height and access. We match the mortar color and composition so the repair doesn’t look like a patch job.
Spalling Brick Repair
Spalling means the brick face itself is flaking, cracking, or popping off, usually because water got behind the surface and froze. On a three-story McLean Colonial with a full-height masonry chimney, we regularly see spalling concentrated on the north and east faces where freeze-thaw cycles hit hardest. Spalling brick repair here runs $900 to $2,400 depending on how many bricks need replacement and whether we’re working from a ladder or scaffolding.
Chimney Waterproofing
McLean’s high summer humidity keeps chimney masonry damp for months, and shaded chimneys in Langley Forest and Chesterbrook can stay wet year-round from tree canopy alone. Waterproofing is a penetrating siloxane treatment, not a paint, and it lets the brick breathe while shedding water. A full waterproofing treatment for a typical McLean chimney runs $500 to $1,100, and we recommend it after any repointing or brick replacement so the new work doesn’t start absorbing water immediately.
Flashing Repair
The flashing where chimney meets roofline is the most common leak point we find in McLean homes, especially on steep rooflines where original flashing was done with thin aluminum or galvanized steel. Flashing repair runs $450 to $900 for a standard front-flashing replacement and $1,100 to $3,000 when the roof side has to be lifted and the whole saddle, apron, and step flashing system replaced. We use copper or powder-coated steel, not the thin stuff that got installed in 1978.

Common Chimney Repair Problems We See in McLean Homes
- Third-degree creosote glaze in seldom-used wood fireplaces. McLean’s decorative fireplaces burn cool and dirty, producing a hard tar glaze that a brush alone can’t remove. That glaze accelerates liner spalling, which becomes a repair job, not a sweep job.
- Freeze-thaw spalling on tall multi-story chimneys. The DC metro’s winter temperature swings repeatedly cross the freezing point, and McLean’s exposed masonry takes the worst of it. Crowns crack, mortar pops, and brick faces flake anywhere water has gotten behind the surface.
- Unlined or undersized flues on gas conversions. This is the big one for McLean, and we’ll dive into it below. The short version: many 1990s and 2000s gas insert installations skipped the liner upgrade Fairfax County’s code required at the time.
- Animal blockages and damp flues in wooded neighborhoods. In Langley Forest and Chesterbrook, mature oak and tulip poplar canopy keeps flues shaded and humid, which attracts chimney swifts, squirrels, and raccoons. We pull animal nests out of McLean chimneys far more often than we do in the more open-lot suburbs like Falls Church or Vienna.

FAQs - Chimney Repair in McLean
Because during McLean’s 1990s and 2000s renovation wave, gas insert conversions were routinely done without the flue liner upgrade Fairfax County’s code required. The original clay tile flue was sized for a wood fire, not a gas appliance venting at lower temperatures, and the smaller gas exhaust volume condenses acidic water vapor inside the flue, which dissolves clay tile from the inside out. We’ve documented this in dozens of McLean homes: the homeowner says “it works fine,” and the camera shows a spalled smoke chamber and a liner that’s actively deteriorating. A gas appliance venting through a compromised flue is a carbon monoxide safety issue, not a performance issue. That’s why we always check liner condition on gas fireplaces, even when the call is for a simple sweep. If you have a gas insert and don’t know what’s in your flue, call us. We’ll show you the camera feed.
Yes and no. Some repointing is normal on a 40-year-old McLean Colonial, but if you’re repointing the same faces every two or three years, the real problem is water getting behind the brick, not just surface mortar failure. Freeze-thaw cycling drives the damage, but it’s water entry that starts it. The fix is usually a combination of repointing, waterproofing, and sometimes a rebuilt crown with a proper drip edge. That’s the long-term solution. Call (240) 290-6726 and we’ll show you where the water’s actually getting in.
Every year, and the reason is specific to McLean’s housing stock. When you have two to four fireplaces per house, the ones you don’t use are the ones that develop hidden problems: animal nests in the unused flue, creosote glaze in the decorative fireplace, a gas insert venting through a liner nobody’s checked since 1997. An NFPA 211 Level 2 inspection with a camera scan covers all the flues in one visit, and it’s cheaper than repairing one failed liner. In McLean, we recommend scheduling inspections in late summer, before burning season starts.
First-degree creosote is soft soot and can be brushed out. Third-degree creosote is a hard, glossy tar glaze that forms when fires burn cool and incomplete, which is exactly what happens in McLean’s decorative fireplaces that get lit a few times a year for ambiance. Third-degree creosote cannot be removed by brushing, and it’s both highly flammable and chemically active enough to accelerate clay tile spalling. When we find third-degree creosote in a McLean fireplace, we treat it as a liner condition problem, not just a cleaning problem. The repair is usually chemical removal plus, in many cases, a liner replacement. Call (240) 290-6726 and we’ll tell you what degree you’re at and what it means.
The difference is tree canopy. McLean’s heavily wooded neighborhoods like Langley Forest, Chesterbrook, and areas along Potomac School Road sit under mature oak and tulip poplar canopy year-round. That shade keeps the top courses of masonry damp for months at a time, which accelerates mortar deterioration and creates exactly the right environment for moss, organic growth, and animal nesting. Chimney swifts, squirrels, and raccoons all prefer shaded, quiet flues, and McLean has more of them than the more open-lot suburbs. A chimney cap with a proper spark arrestor and a waterproofing treatment on the top three feet of masonry is the standard fix. We do these together all the time on McLean jobs.
