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.

AfterDuraFlex Chimney Cleaning in Arlington, DC | Level Two Chimney Washington
A DuraFlex chimney cleaning in Arlington runs $189 to $389 for most single-flue homes, depending on liner condition, creosote class, and whether the flue serves a wood-burning fireplace or a gas log set. Level Two Chimney Washington is an independent DuraFlex service provider, not a manufacturer affiliate or authorized dealer. We clean, inspect, and repair DuraFlex liners across Arlington’s older brick housing stock, and our camera-scan documentation is standard on every job. Call (240) 621-1264 for a written quote before any work starts.
What makes our DuraFlex work different in Arlington specifically? Most of the county’s single-family chimneys are 70 to 90 years old, and a large share of the gas-log conversions from the 1980s and ’90s pushed gas exhaust into oversized clay flues that were never properly lined. That means a DuraFlex liner in Arlington is often living inside a compromised chimney, and the cleaning is as much a liner audit as anything else. We cover DuraFlex DuraFlex sales & service with genuine components, written pricing, and a photo record you keep.
Why Arlington Residents Choose Us for DuraFlex Service
Our techs handle DuraFlex liners in Arlington’s aging masonry chimneys every week, from gas-log retrofits in Ashton Heights to wood-burning multi-flue systems in Lyon Park. We know how DuraFlex’s double-wall aluminum and stainless products behave under Arlington’s freeze-thaw cycles and inside its famously oversized flues. That’s not manufacturer training, it’s field repetition.
Corrine Halstead, owner of Level Two Chimney Washington, picked up her first rotary brush through an Apex Technical School trade program in Manhattan before spending fifteen years running chimney cleaning and inspection work across DC and Northern Virginia. Her crews document everything: liner condition, camera footage, written scope, written warranty. The camera doesn’t lie, and neither does the written price.
We use genuine DuraFlex components, connectors, caps, and termination kits sourced from local distributors. Aftermarket couplers often have sloppy tolerances that leak in Arlington’s high-draft chimneys. We don’t install knockoffs on a liner that’s venting gas into your living space.
Common DuraFlex Chimney Cleaning Problems We Solve in Arlington
- Aluminum liner corrosion from oversized clay flues. In Lyon Park and other 1930s-1950s neighborhoods, a 4-inch aluminum DuraFlex liner sitting inside an original 8×12 clay flue vents a gas log set every winter. The dead air space sweats, condensation forms, and the aluminum develops acid pinholes. We camera-scan first, then tell you plainly whether it can be cleaned or needs replacement.
- 304L stainless kinking at the smoke shelf offset. Old Arlington terra-cotta flues have tight bends where the smoke chamber meets the flue. If a previous installer pulled a DuraFlex liner through a 70-year-old offset without a proper pull cone, the liner can kink right there. Creosote loves to collect behind that kink. We find them with the camera and document the spot.
- Uninsulated liners sweating in exterior chimneys. Arlington’s winter temperatures swing above and below freezing multiple times a week. An uninsulated DuraFlex liner in an exterior masonry chimney condenses flue gases constantly during those swings, and the acidic condensate eats the liner from the inside. This is the most common DuraFlex-specific failure we see in North Arlington and along the Rosslyn corridor.
- Liner chafing against cracked clay tiles. Multi-flue chimneys from the 1940s often have two flues: one for a wood-burning fireplace, one for an old fuel-oil furnace. Decades of differing thermal expansion crack the clay. A DuraFlex liner rubbing against those fractured edges wears through the outer wall. We inspect both flues independently, every visit.
- Blocked connectors and termination caps. Arlington’s tree canopy, the oaks in Dominion Hills especially, drops enough debris that termination caps clog within a season if they’re the wrong style for the flue. We stock the correct DuraFlex caps locally for faster turnaround.
BeforeAfterDuraFlex Service in Arlington: What Local Conditions Mean for Your Equipment
Arlington County’s permit office actively flags unpermitted gas-log conversions during home-sale inspections. This is a known pressure point in the county’s real estate market, and it shapes our DuraFlex work uniquely. We regularly get calls not from a homeowner who wants a chimney cleaning, but from a real estate agent in Ashton Heights or Lyon Park trying to clear a red flag before closing. The inspector found a gas log set venting into an original clay flue with no listed liner, or with a liner that’s visibly deteriorated, and the sale stalls.
For a DuraFlex owner, that call usually means one of two things. Either the liner is aluminum and has pinholes that fail a Level 2 camera inspection, or it’s 304L stainless but was installed without a proper top plate, and the crown has cracked enough that water is running down the outside of the liner. Our job is to document the actual condition, on camera, with a written report the county permit office will accept. We’ve done enough of these in Arlington to know what the office looks for. A 1940s brick colonial in Ashton Heights with a 1987 gas-log conversion, a 4-inch aluminum DuraFlex liner that was never insulated, and acid pinholes running the full length, we pulled it and dropped a new 304L stainless DuraFlex with a proper top plate. The county cleared the permit before the sale closed. That’s Clause 4 of the Haven Standard in action: a photo record on every job, running continuously since 2009.
DuraFlex Models & Products We Service in Arlington
We service the full residential DuraFlex line: the 304L Stainless Steel Liner for wood-burning and multi-fuel applications, the Aluminum Liner for gas-only venting, the Pro Series Insulated Liner for high-efficiency appliances and exterior chimneys, and the Flexible Connector for appliance hookups. Our approach is OEM-first. DuraFlex connectors and termination kits fit correctly the first time, and we stock the common Arlington sizes locally so replacement parts don’t mean a two-week wait.
When a liner is kinked or corroded beyond a patch, we recommend full replacement. A band-aid fix on a gas-venting liner isn’t something we’ll put our name on, and the 365-Day Done Right Promise applies either way.

FAQs - DuraFlex Chimney Cleaning in Arlington
Yes, Virginia residential code and NFPA 211 both require a properly sized liner for gas appliances venting through a masonry chimney, and a 1950s Arlington home with a ’90s conversion almost certainly needs verification. We inspect the existing liner with a camera, measure the flue, and document whether it meets current code. Call (240) 621-1264 to book the scan.
Yes. Arlington’s freeze-thaw cycling and the oversized clay flues common in 1930s-1950s housing push aluminum liners into condensation territory far more often than stainless. Aluminum is gas-only approved, and in an uninsulated exterior-chimney application in Arlington, we see pinhole corrosion within 10 to 15 years. Stainless 304L holds up far longer.
Yes. We can line the fireplace flue for wood burning while leaving the second flue capped or reserved for a future appliance, if it’s structurally sound. Both flues get independent camera inspection first, because a 1930s Lyon Park chimney almost never has two flues in identical condition. The written quote covers each flue separately.
Usually yes. If the brick face is spalling, water has been getting behind it, and that same moisture has likely compromised the liner connection or the mortar bed around it. We pull the liner when needed, repair the masonry, then install a new genuine DuraFlex liner with a proper top plate, as part of our Chimney Repair - Arlington service. Patching brick around a failing liner hides the problem.
Yes. This is one of the most common calls we get in Arlington. We run a Level 2 camera inspection, document the liner condition and flue sizing, provide the written report and photos the county permit office wants to see, and install a code-compliant DuraFlex liner if the existing one fails. Call (240) 621-1264 and we’ll schedule it around your closing timeline.
