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.
Fast, Reliable Chimney Cleaning & Sweep Across Ashburn
A chimney cleaning and sweep in Ashburn typically runs $189-$289 for a standard gas fireplace, and $229-$349 when we’re also pulling the camera down the flue for a Level 2 inspection through our Ashburn Fireplace Services. Most Ashburn homes we service were built between 1993 and 2015, and the factory-built gas fireplaces in those houses are now old enough to have real problems hiding behind the wall. We coordinate scheduling from our Washington, DC office and send background-checked, uniformed technicians into Ashburn communities like Broadlands, Brambleton, and Belmont every week. If you want a written price before anyone steps inside your door, call (240) 220-9395.
Why Level Two Chimney Gaithersburg Is Ashburn’s Preferred Chimney Cleaning & Sweep Company
We’ve cleaned and inspected more than 38,000 chimneys since 2009, and a large share of those are in Ashburn’s planned communities. What Ashburn homeowners tell us they value most is the camera. Every visit includes a documented photo record, per Clause 4 of the Haven Standard, which means you see exactly what we saw inside your flue. No flashlight-and-handwave. When we find a rusted chase cover or a separated B-vent seam, we show you the image and explain what it means in plain terms before we quote anything.
Our Ashburn customers consistently mention three things in reviews: the written price before work starts, the technician’s license number displayed on the page, and the fact that a real person answers the phone 24/7. That last one matters when you’re standing in front of a cold fireplace on a January morning and wondering if the gas valve is safe to light. Corrine Halstead, who leads our team, set the standard early: no job proceeds without a written scope and written warranty delivered first. That’s Haven Standard Clause 1, and it has never been negotiable.
Our Chimney Cleaning & Sweep Services in Ashburn

Ashburn’s housing stock is overwhelmingly factory-built gas fireplaces in homes from Toll Brothers, NV Homes, and similar volume builders. That changes what a proper sweep looks like. We’re not shoving brushes up a masonry flue and calling it done. We’re inspecting metal liners, chase covers, draft seals, and termination caps, then cleaning what actually needs cleaning. Our Chimney Cleaning & Sweep team handles the full range, but these four services cover most of what Ashburn needs.
Level 1 Inspection
A Level 1 inspection is the baseline check for a fireplace that has been used regularly and shows no signs of trouble. In Ashburn, we perform Level 1 work most often on gas fireplaces that homeowners light a few times each winter. We check the accessible portions of the flue, the chimney cap, the firebox, and the gas valve operation. The written report tells you whether the unit is safe to use this season, not just whether it’s dirty.

Level 2 Inspection
This is the camera-down-the-flue standard required by NFPA 211 whenever a home changes hands, or after weather events, or if the fireplace hasn’t been used in years. In Ashburn, Level 2 inspections are the single most important service we offer. Because most direct-vent and B-vent gas fireplaces hide their flue liners inside framed chases, the only way to see a separated seam or rust perforation is with a camera. If you bought your Ashburn home between 2015 and 2025 and never had the fireplace checked, start here.

Creosote Removal
Yes, gas fireplaces can accumulate creosote-like residue. In Ashburn’s humid summers, moisture entering a dormant flue coats the liner walls and traps fine soot and dust, forming a sticky film that builds up over repeated cycles. If you occasionally burn those store-bought duraflame logs in a wood-burning prefab unit, the creosote can reach Class II or even Class III, which is a glazed, tar-like coating that standard brushing won’t remove. We use rotary whip systems and chemical treatments appropriate to the creosote class we document on camera.

Soot Removal
Soot removal matters even in gas systems because the dark residue on your firebox walls and glass isn’t harmless. It signals incomplete combustion, which can mean a draft problem, a dirty burner, or a failing seal. We clean the firebox, burner, and log set, then verify the draft seal integrity so exhaust goes up the flue instead of into the room. Ashburn homes with direct-vent fireplaces in tight, energy-efficient enclosures are especially prone to draft-seal degradation that causes exactly this.

When your 2004 direct-vent unit needs a new termination cap or a replacement draft seal, we can usually source the specific part through our buying network and have it on the truck for the next trip to your neighborhood. No “we’ll order it and come back in three weeks” runaround.
Common Chimney Cleaning & Sweep Problems We See in Ashburn Homes

- Rusted-through galvanized chase covers. The builder-grade steel covers installed on 1990s and early 2000s Ashburn chases are now failing, and the first sign is usually a rust stain streaking down the brick or siding. HOA architectural review boards in Broadlands and Brambleton flag these stains regularly.
- Separated B-vent seams behind the wall. Metal flue liner sections in older B-vent systems can pull apart at the elbows, especially in homes where the chase has shifted slightly from freeze-thaw cycles. A camera inspection catches this before exhaust leaks into the wall cavity.
- Draft-seal failures in rarely used fireplaces. When a gas fireplace sits unused for months, its seals dry and crack. Then the first cold night arrives, you light a fire, and products of combustion backdraft into the room. We see this pattern constantly in Ashburn townhomes.
- Moisture-driven flue corrosion from humid summers. Ashburn’s high summer humidity pushes moisture into dormant flues, where it sits against metal liners and promotes rust. By the time you notice a problem, the liner may already be perforated.

FAQs - Chimney Cleaning & Sweep in Ashburn

Because the metal flue liner, chase cover, and draft seals in a 1998 gas fireplace are now 25-27 years old, and they fail whether or not you use the fireplace. Moisture gets in through a rusting chase cover, humid summer air corrodes the liner, and dry seals crack. When you finally light it on a cold night, a failed seal can let carbon monoxide into the room. A camera inspection costs $229-$289 and shows you the actual condition inside the flue. Call (240) 220-9395 to schedule one.
Rusted chase covers, by a wide margin. The original galvanized steel covers installed on 1990s and early 2000s homes are now rusting through, which stains the brick or siding below them and triggers HOA architectural review notices. We replace them with painted-aluminum covers that won’t rust, typically for $350-$650 installed. Call (240) 220-9395 and we’ll bring the camera out to confirm what’s actually leaking.
Yes. Class III creosote is the glazed, tar-like form that brushes alone won’t touch. You need either rotary whip cleaning, a chemical treatment, or both, depending on what our camera shows. In Ashburn, this glazed creosote is most common in prefabricated wood-burning fireplaces that homeowners used with store-bought logs a few times each winter for 20 years. Expect to add $75-$150 to the cost of a standard cleaning. Call (240) 220-9395 for a written quote after the inspection.
Rust stains on the firebox floor or walls of a direct-vent gas fireplace almost always mean water is getting in from above. The usual culprit in a 20-year-old Ashburn home is the chase cover, which has rusted through and is letting rain drip down onto the firebox. Sometimes a failed termination cap gasket is the issue. We diagnose it with the camera, replace the failed component, and clean the rust residue so the unit looks and runs correctly. A written quote comes before any work, always.
NFPA 211 recommends an annual inspection with cleaning as needed, and that holds for gas fireplaces in Ashburn even if you never light them. Gas systems build up dust, insect nests, and flue-film residue from humid air, and their seals dry out over time. Once a year, before burning season, is the right cadence. Call (240) 220-9395 to schedule your annual check. We’ll give you a written price before anything starts, and you’ll walk away with a photo record of exactly what we found.
