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 Cleaning & Sweep Across McLean
A chimney cleaning and sweep in McLean typically costs $189-$389 depending on the number of flues, creosote condition, and whether you’re adding a camera inspection. For homes with two to four fireplaces, which is common across McLean’s larger Colonials and Tudors, the work takes longer and pricing reflects that. We’re the McLean chimney team that shows up with a named tech, a written price in hand, and a camera that goes down every flue before anyone touches a brush. Call (240) 290-6726 and you’ll talk to a live person who can book your sweep and tell you exactly what to expect.
Why Level Two Chimney Alexandria Is McLean’s Preferred Chimney Cleaning & Sweep Company
McLean homeowners don’t call us because we say we’re good. They call because neighbors in Langley Forest, Chesterbrook, and along Old Dominion Drive have seen what our crews document. Every job ends with a photo record of the flue interior, not a verbal summary. That practice, Clause 4 of the Haven Standard, has been our default since 2009, and it’s now the expectation for anyone working on a McLean chimney.
Our Chimney Cleaning & Sweep team works McLean weekly. We know the difference between a 1960s Colonial off Chain Bridge Road and a 1980s contemporary near Great Falls Street. We know which flues in a three-fireplace Tudor were likely converted to gas in the 1990s and never relined. And we know that in heavily wooded pockets like Langley Forest, a chimney that hasn’t been used in three years may now contain a squirrel nest, not just dust.
Corrine Halstead runs the operation, and she’s built the crew around a simple rule: evidence first. If we say your liner has a gap, you’ll see the photo. If we say the creosote is third-degree tar glaze, you’ll see the scope footage. No scare tactics, no upselling you can’t verify on the spot.
McLean customers also appreciate that we don’t ask for a deposit or a signature before the written scope is in your email. The price is the price. It’s on paper before work starts, and it doesn’t change because the tech found something mid-job.
Our Chimney Cleaning & Sweep Services in McLean
Level 1 Inspection
A Level 1 inspection checks the readily accessible portions of the chimney, flue, and appliance connections. For McLean homes with multiple fireplaces, we do this on every flue, not just the one you use. The inspection is included with every sweep, and the findings are photographed as part of your documented record.
Level 2 Inspection
Level 2 is the camera-scan inspection. It’s required when you’ve changed the appliance, converted to gas, had a chimney fire, or bought the home. In McLean, where gas insert conversions from the 1990s and 2000s skipped Fairfax County liner upgrades with regularity, this inspection frequently finds unlined or undersized flues venting gas appliances. That’s not a cleaning issue. That’s a carbon monoxide exposure issue. The camera tells us which one you have.
Creosote Removal
Creosote builds up as a byproduct of wood combustion, and in McLean’s cooler, damp winters, it doesn’t stay dry. Homes in shaded neighborhoods like Chesterbrook and Langley Forest often have first-degree creosote in secondary flues that haven’t been burned in years. That material is still combustible and still blocks proper draft. We remove it with rotary tools sized to your flue, then scope the flue again to verify. Third-degree tar glaze, which we see in flues that ran hot then sat dormant, usually requires chemical treatment or a liner, not just a brush.
Soot Removal
Soot removal is for gas fireplaces and inserts, or for wood-burning fireboxes after heavy seasonal use. If your McLean home has a gas insert in the family room and a wood-burning fireplace in the living room, both need attention. Soot from gas logs is acidic and sticky, and it accelerates metal deterioration on the damper and firebox components. We clean it, document it, and tell you if the insert’s venting is safe.
Annual Sweep
For a McLean Colonial with three fireplaces, an annual sweep isn’t a luxury. It’s the inspection regime that catches a blocked secondary flue, a deteriorating crown, or a gas venting problem before it becomes a house fire or a CO event. We recommend scheduling in late summer or early fall, before burn season, and before chimney swifts return in spring to nest in uncapped flues.

BeforeAfterTrusted Brands We Service in McLean
We work with liners and components from HeatShield, Gelco, and Olympia Chimney. That matters for McLean homeowners because when a liner fails or a crown needs a poured repair, we’re not ordering parts from a catalog and hoping they fit. We’re using the same materials we install on dozens of chimneys across McLean every year. If your gas insert is venting into an unlined 1960s flue and needs a HeatShield liner, we’ll quote it in writing, show you the camera footage, and schedule the install before burn season. No vague recommendations. No “we’ll get back to you.”
Common Chimney Cleaning & Sweep Problems We See in McLean Homes
- Raccoon and squirrel blockages in shaded flues. McLean neighborhoods like Langley Forest and Chesterbrook have mature oak and tulip poplar canopies that keep chimney tops damp and inviting. We pull animal nests from flues here far more often than in open-lot suburbs like Falls Church or Vienna.
- Unlined gas flues from 1990s conversions. Many McLean Colonials and Tudors converted wood-burning fireplaces to gas inserts during the 1990s renovation wave, and Fairfax County’s liner upgrade requirements were skipped. The gas appliance is venting into an unlined masonry flue, which is a code violation and a CO-safety issue. A routine sweep that ignores this leaves the homeowner exposed.
- Third-degree creosote in secondary flues. Multi-fireplace McLean homes often have one fireplace that gets all the use while the others sit dormant. Creosote still accumulates in the unused flues, sometimes hardening into tar glaze that a standard brush can’t remove. We see this consistently in three-fireplace Colonials along Old Dominion Drive.
- Moss and spalling on shaded crowns. The DC metro freeze-thaw cycle is hard on exposed masonry, but in McLean’s wooded lots, high humidity and shade keep crowns damp for months. Moss grows into hairline cracks, water expands when it freezes, and the crown starts to spall. A cleaning alone doesn’t fix that, but an annual sweep is when we catch it before the water reaches the firebox.
Pricing for Chimney Cleaning & Sweep in McLean, VA
A single-flue chimney sweep in McLean typically runs $189-$249. A two-flue home, common in smaller split-levels and ramblers near Westmoreland Street, runs $249-$319. A three-to-four-flue Colonial or Tudor, which is the McLean norm in neighborhoods like Langley Forest and along Chain Bridge Road, runs $329-$389. If we add a Level 2 camera inspection because you converted to gas or just bought the house, plan on $99-$149 extra, and we’ll send the footage to your phone before we leave.
What changes the price is creosote condition. Third-degree tar glaze requires chemical treatment, rotary removal, or a liner, and that’s quoted separately after the camera shows us what’s there. We give you the written price before anything starts, and the written warranty after it’s done. Call (240) 290-6726 for a free estimate on your McLean chimney.

FAQs - Chimney Cleaning & Sweep in McLean
Every flue should be swept and inspected annually, even the ones you don’t burn. Unused flues in McLean homes still accumulate creosote from prior use, and they’re where animals nest, damp chimney caps grow moss, and gas exhaust gets blocked. A three-fireplace Colonial on Old Dominion Drive needs three flues inspected, not one. Call (240) 290-6726 and we’ll quote the whole house, not just the main fireplace.
Yes, because the venting is often the problem, not the firebox. Many 1990s gas insert conversions in McLean skipped the Fairfax County liner requirement, so the insert vents into a bare masonry flue. That causes condensation, acidic soot buildup, and carbon monoxide risk inside the home. A Level 2 camera inspection will show us exactly what’s behind that insert. If you haven’t had the flue scoped since the conversion, call (240) 290-6726 and we’ll schedule it.
McLean’s tree canopy is the difference. Neighborhoods like Langley Forest and Chesterbrook have mature oaks and tulip poplars that overhang rooftops and keep chimney tops shaded, damp, and quiet. That’s ideal nesting habitat for chimney swifts, squirrels, and raccoons. Open-lot suburbs like Vienna and Falls Church have fewer overhanging branches and less animal pressure. The fix is a proper chimney cap with a screen, and we’ll show you the nest before we remove it.
Third-degree creosote looks like hardened tar glaze, shiny and black, baked onto the flue walls. It forms when a flue runs hot, then sits dormant through humid seasons, and it’s common in McLean’s multi-flue Colonials where secondary fireplaces rarely get used. A standard wire brush skates over it. Rotary tools can sometimes remove it, but often the flue lining is compromised and a liner like HeatShield is the actual fix. We’ll show you the scope footage and tell you which path yours needs. Call (240) 290-6726 for a camera inspection.
It’s a repair issue that we catch during cleaning. Moss grows in the cracks, holds water, and the freeze-thaw cycles in the DC metro area expand those cracks until the crown spalls. In McLean’s shaded neighborhoods, this happens faster than on open-lot chimneys. If we see it during your sweep, we’ll document it, explain whether it can wait, and give you a written repair quote. You decide, and you’ll have the photos to back up whatever we recommend.
