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.

Why Level Two Chimney Washington Is Gaithersburg’s Preferred Chimney Cleaning & Sweep Company
Gaithersburg homeowners call us because we show them what we found. Every visit ends with a photo record of your flue, your liner, your crown, and any creosote we removed. That’s Clause 4 of the Haven Standard, and we’ve built every inspection around it since 2009. No other company serving Gaithersburg has been documenting chimneys with camera scans that consistently for that long.
Our Gaithersburg customers read the three-star reviews before they call. They’ve heard stories about techs who showed up, shined a flashlight, and handed over a bill for “inspection” that never involved a camera. That’s not what we do. Corrine Halstead and our uniformed, background-checked technicians arrive with a named tech assigned to your job and a text when they’re on the way, per the H.A.V.E.N. standard for verified crews and on-time arrival.
We answer the phone with a live person, 24/7. Not a voicemail. Not a web form. When you call (240) 621-1264 at 9:30 at night because you smell smoke in your Montgomery Village townhome, someone picks up.
Our Chimney Cleaning & Sweep Services in Gaithersburg
Level 1 Inspection
A Level 1 inspection checks the readily accessible portions of your chimney and fireplace: flue interior, damper function, firebox condition, and clearances. For Gaithersburg townhome owners in Montgomery Village, a Level 1 is the right call when you’ve been burning regularly and nothing has changed about the system. It’s included with every annual sweep, not billed as a separate line item.
Level 2 Inspection
A Level 2 inspection is what NFPA 211 requires when you’re buying or selling a home in Gaithersburg, or when something has changed: a new appliance, a chimney fire, a storm, or a smoke smell you can’t explain. We run a camera down the full length of the flue and document every frame. In Gaithersburg’s Montgomery Village specifically, this inspection is where we verify the flue separation wall inside shared chimney stacks is intact. A collapsed clay tile can breach that dividing wall and let smoke or carbon monoxide migrate into the neighboring unit. That’s not a theoretical risk here; it’s a documented pattern in 40-to-60-year-old townhome stacks.
Creosote Removal
Creosote removal in Gaithersburg is a seasonal urgency. Our Piedmont summers are humid, and wood-burning fireplaces that sit idle from April through October develop stage-2 creosote faster than you’d expect. By November, when Gaithersburg homeowners light the first fire of the season, we’re routinely seeing glaze that requires mechanical removal rather than a simple brush sweep. We remove Class I, II, and III creosote using rotary loops and hand tools sized to your flue dimensions, and we photograph the before and after.
Soot Removal
Soot removal is part of every sweep we perform in Gaithersburg, but it matters more in Kentlands and Lakelands single-family homes where decorative gas-log inserts sit in original wood-burning fireplaces. Gas logs still produce soot, and they hide what’s behind them: a missing damper, a rusted smoke shelf, or a flue that was never converted properly for gas venting. We remove the log set, clean the soot, and photograph what we find.

We work on every major chimney system found in Gaithersburg homes, from original 1960s-era clay tile flues in Montgomery Village to prefabricated metal chimneys in newer Kentlands construction. When a liner or cap needs replacing, we source from Gelco and Copperfield, with materials procured through the Haven buying network specifically to keep prices honest for Gaithersburg homeowners. We stock common components locally, which means less waiting when your cap is rusted through and winter is two weeks out.
Common Chimney Cleaning & Sweep Problems We See in Gaithersburg Homes
- Shared-stack flue separation failure in Montgomery Village. Adjacent townhomes share a single exterior chimney stack with two flues running side by side. A collapsed clay tile can breach the dividing wall and allow smoke or carbon monoxide into the neighbor’s home. Only a camera inspection during the sweep catches the breach before it becomes a CO incident.
- Freeze-thaw spalling on original 1970s brick chimneys. Gaithersburg sits around 500 feet elevation in the Piedmont transition zone and averages 20 inches of snow per year with frequent ice storms. That’s more freeze-thaw cycling than Washington, DC proper, and it accelerates mortar joint failure and brick spalling on the older chimney stacks throughout Montgomery Village.
- Accelerated creosote buildup from humid summers. Region-wide summer humidity promotes faster stage-2 creosote development in wood-burning systems that sit idle from April through October. Gaithersburg homeowners often don’t realize how much glaze has formed until the first burn, when it’s already a removal job rather than a standard sweep.
- Gas-log inserts treated as maintenance-free in Kentlands and Lakelands. Decorative gas-log sets still fill flues with soot and can hide a missing or rusted damper. Level 1 inspections routinely flag these, and the fix is usually straightforward if caught before the damper seizes entirely.

FAQs - Chimney Cleaning & Sweep in Gaithersburg
Yes. In Montgomery Village, adjacent units routinely share a single exterior chimney stack with two separate flues running side by side. A collapsed clay tile can breach the dividing wall and allow smoke or carbon monoxide to migrate into the neighbor’s home. We discovered exactly this on a townhome off Montgomery Village Avenue: a collapsed clay tile had breached the shared stack. We installed a HeatShield resurfacing system to restore flue integrity before recommissioning the fireplace. If you smell smoke from an adjacent unit’s fireplace, call (240) 621-1264 the same day.
Gaithersburg sits at roughly 500 feet elevation in the Piedmont transition zone, with an average of 20 inches of snow per year and frequent ice storms. That’s measurably more freeze-thaw cycling than DC proper, and it drives spalling and cracked mortar joints on the original 1970s brick chimney stacks throughout Montgomery Village. Water gets into the flue, and that water accelerates third-degree creosote formation. The fix is usually tuckpointing and a waterproof crown seal, not a full rebuild, if you catch it before the damage reaches the flue liner.
Yes, and the reason is specific to Gaithersburg. Our humid Piedmont summers promote stage-2 creosote development even in flues that were swept the previous spring. A few burns per season is enough to deposit a thin layer of creosote, and six months of idle humidity turns that layer into glaze. The inspection matters as much as the cleaning. For shared-stack Montgomery Village townhomes, the annual sweep is also when we verify flue separation is intact, which you cannot check from the firebox.
Yes. Gas logs burn cleaner than wood, but they still produce soot, and they hide what’s behind them: a missing damper, a rusted smoke shelf, or a flue that was never properly converted for gas venting. A Level 1 inspection on a gas-log fireplace in Kentlands routinely turns up issues that have been sitting there since the home was built in the 1990s. Call (240) 621-1264 and we’ll document the flue condition so you can decide with photos in hand.
We look for three things on every shared-stack townhome in Montgomery Village: flue separation integrity, creosote class, and crown condition. Flue separation is the one that matters for your safety and your neighbor’s. A collapsed clay tile can breach the dividing wall, and the only way to see it is with a camera scan during the sweep. We also check for spalling brick and mortar joint failure caused by Gaithersburg’s freeze-thaw cycles, because water intrusion accelerates every other chimney problem. You walk away with a photo record of all of it, which is Clause 4 of the Haven Standard and has been our default since 2009.
If you own a home in Gaithersburg and want a chimney sweep that documents what it finds, call (240) 621-1264. We’ll give you a written price before work starts, a camera-scan inspection on every visit, and a photo record when we’re done. Corrine Halstead and our Gaithersburg crews answer the phone around the clock.
