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 & Sweep in Annapolis: What to Know First
We clean and inspect DuraFlex chimney systems throughout Annapolis with a camera down the flue and a written price in your hand before any work starts. A standard DuraFlex sweep and Level 2 inspection runs $289-$429 in this market, depending on flue height, accessibility, and how long it’s been since the last cleaning. The camera footage and photo record come with every job, whether the findings are simple or complicated.
This page is for Annapolis homeowners who own a DuraFlex liner or chimney system and want someone who actually knows how that product ages, what its serial failures look like, and when a sweep is enough versus when the liner itself needs real attention. We’re an independent DuraFlex service provider, not a manufacturer-authorized shop, and that matters: we have no incentive to sell you parts you don’t need. Call (443) 274-4231 and a live person answers, 24 hours a day.
How DuraFlex Products Fail - and How We Fix Them
- DuraFlex 316L liners and salt-air pitting in Eastport and waterfront homes. The 316L alloy is good material, but Annapolis humidity and salt spray accelerate surface pitting on the inner wall, especially in chimneys that vent gas appliances and rarely get hot enough to burn off condensation. We see this on liners installed eight to twelve years ago. The fix is usually a thorough sweep with nylon brushes, not steel, followed by a camera pass to measure pitting depth. If the pitting is surface-level, the liner stays. If it’s through-wall anywhere, that section gets replaced.
- DuraFlex Pro connectors separating at the seam after repeated thermal cycling. Connectors take the brunt of expansion and contraction. On wood-burning fireplaces in older Annapolis homes, the seams between connector sections can loosen over five to seven seasons, especially where the liner makes the bend at the smoke chamber. We catch this on camera before it becomes a leak into the chimney chase. The fix is a reseat of the joint and, where necessary, a replacement connector, which we keep in the truck for common DuraFlex diameters.
- Class III creosote glaze in DuraFlex smooth-wall liners used for frequent wood burning. Smooth-wall liners are easier to sweep than corrugated, but they’re not immune. When homeowners burn unseasoned wood or run fires low and slow, creosote bakes into a hard glaze that a standard sweep won’t remove. We identify the class on camera, then use a rotary chain whip designed for smooth-wall stainless, followed by a camera verification. If we don’t get it clean, we say so and show you the footage. Clause 4 of the Haven Standard requires that photo record on every job we do.
- DuraFlex ovalized liners collapsing slightly under masonry pressure in older chimneys. This is a homeowner-visible symptom: a liner that’s no longer round when you look down from the top. It happens when the original clay tile flue shifted and pressed against the liner. Most ovalization is cosmetic, but we measure the cross-section on camera and compare it to the appliance’s minimum flue area. If it’s under spec, you need a liner replacement, not a sweep. We’ll show you the measurement in the video and write it in the report.
- DuraFlex rain caps and termination kits coming loose at the crown in high-wind exposure. Annapolis gets real wind off the Severn and the Bay, and we regularly find termination caps that have walked loose from the liner’s top ring. A loose cap lets rain in, and rain mixed with creosote makes an acidic slurry that accelerates liner corrosion at the top three feet. We reseat and resecure the cap and inspect the crown seal during every sweep. It’s a two-minute fix that prevents a four-figure liner problem.
Our DuraFlex Chimney Cleaning & Sweep Process
Every DuraFlex job in Annapolis follows the same sequence, and nothing gets skipped. Corrine Halstead set this process years ago and we don’t deviate from it.
- 1
Call and schedule. A live person answers, takes your address, and asks what appliances vent into the chimney and when it was last swept. If you have photos of the setup, we want them.
- 2
Camera-first inspection. Before any brush touches the flue, we run the camera down and document the liner’s condition, seam integrity, creosote class, and cap status. You see the footage too.
- 3
Written scope and price. We tell you what the camera found, what we recommend, and what it costs. Written, not verbal. We don’t start work until you’ve read it and signed it. That’s Clause 1 of the Haven Standard.
- 4
Sweep and any needed repairs. We use liner-safe brushes sized to your DuraFlex diameter, plus rotary tools for glaze. If a connector, cap, or section needs replacing, we use OEM DuraFlex parts where available and quality aftermarket equivalents when they’re the better value. We tell you which one and why.
- 5
Post-work camera verification. We run the camera again after the sweep. You see the before and after. If something’s still not right, we fix it before we call the job done.
- 6
Documentation and warranty. You walk away with the photo record, the written scope, the written price, and the written warranty. The 365-Day Done Right Promise is stamped on the paperwork: if it’s not done right, we make it right.
BeforeAfterWhat DuraFlex Chimney Cleaning & Sweep Costs in Annapolis
Here are the real numbers for the DuraFlex jobs we handle most often in Annapolis. These aren’t teaser prices and we don’t add surprise line items after the fact.
- Standard DuraFlex sweep with camera inspection (Level 2): $289-$379 for a single-flue chimney with reasonable roof access.
- Two-flue home or difficult roof access: $379-$429. Older Annapolis rooflines, especially on brick Colonials and waterfront homes with steep pitches, take longer.
- Class III creosote glaze removal (rotary whip): $150-$250 add-on, depending on flue length.
- DuraFlex connector or cap replacement during a sweep: $85-$180 parts and labor, depending on diameter and access.
What moves the price: flue height, roof pitch, how long since the last sweep, and whether the creosote has glazed. What doesn’t move it: the way your house looks, the car in your driveway, or how busy our schedule is. The price you sign is the price you pay.

Why Annapolis Homeowners Call Level Two Chimney Annapolis for DuraFlex Work
Most of our DuraFlex customers in Annapolis came to us after another company gave them a quote they couldn’t verify. They were told the liner was failing and they needed a full replacement, but nobody showed them footage that proved it. We do that differently. Every inspection includes the camera run, and the photo record is yours to keep. If your liner is fine, we tell you it’s fine and we put it in writing.
Our techs are background-checked and uniformed, with license information printed on every job document. They’ve worked on hundreds of DuraFlex systems in this area, from wood-burning fireplaces in Murray Hill to gas furnaces in Hillsmere. When a DuraFlex liner has run its course, we also work with HeatShield and Gelco systems, which gives us the ability to recommend the right replacement for your setup rather than the one we happen to sell. The 365-Day Done Right Promise applies to every DuraFlex job we do in Annapolis. If we miss something, we come back and make it right.
FAQs
Every year if you burn wood, and every one to two years for gas appliances, even if the liner looks clean. Salt air and humidity in Annapolis accelerate the kind of slow corrosion that a camera catches but your eyes won’t. A skipped year is rarely a savings. Call (443) 274-4231 to schedule and we’ll give you a firm written price before the tech arrives.
No, provided the sweep uses liner-safe methods appropriate to your liner type. We use brushes sized to your exact DuraFlex diameter and rotary tools only when glaze requires it. The camera record we provide documents that the liner was maintained correctly, which actually helps if you ever file a warranty claim. We’ll include the pre- and post-sweep footage in your job file.
Yes, and you’ll see the evidence. The camera measures pitting depth, seam separation, and cross-sectional distortion, and we show you the footage on-site. If the liner is serviceable, we say so. If it’s not, we write down exactly why with the measurements. You’re never asked to take a recommendation on trust.
Common parts like connectors, top plates, and rain caps for standard DuraFlex diameters are on our trucks. Less common sizes or full liner kits are ordered and typically arrive within a few business days. We’ll tell you before any work is scheduled what’s in stock and what isn’t, and the written quote reflects real lead times.
Most Annapolis jobs are scheduled within three to seven days, and we keep slots open for urgent situations where a flue is blocked or backdrafting. Fireplace season in Maryland runs roughly October through March, and the best time to book is late summer before the rush. Call (443) 274-4231 and we’ll find you a time that works.
