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
DuraFlex chimney cleaning and sweep in Annapolis runs $189 to $289 for a standard annual sweep, and we usually get it done in under two hours once we’re on site. That price includes a camera inspection of the liner and a plain-English report of what we saw. If your DuraFlex liner doesn’t need cleaning yet, we’ll tell you that too, and you won’t pay for a sweep you didn’t need.
This page is for Annapolis homeowners who have a DuraFlex chimney liner and want a sweep who actually knows how it’s put together. Not a franchise that sends a different face each year. Call (240) 851-3653 and a live person answers, day or night, and it may well be Wendell Pike himself.
How DuraFlex Products Fail - and How We Fix Them
- DuraFlex 316L single-wall liners eat creosote differently than terra cotta. The corrugated stainless walls create more surface area than a smooth clay flue, so first-degree creosote builds faster in the ridges. On wood-burning fireplaces in Annapolis, we see this most often in homes along the water where damp, salty air adds moisture to the burn. Fix: an aggressive creosote removal pass with a poly brush sized to the corrugation, followed by camera verification that the ridges are clean. Skip the ridges and you’ve left kindling inside your flue.
- DuraFlex Pro 316Ti shows pitting at the tee connection on oil and gas appliances. The tee is where condensation from acidic exhaust settles, and we’ve pulled liners in Annapolis where the tee looked like Swiss cheese while the rest of the liner was sound. That pitting thins the wall and invites exhaust leakage. Fix: during the sweep, we inspect the tee and the first three feet above the appliance collar. If the pitting is surface-level, we wire-brush and treat it. If the wall is compromised, we replace the tee section only - you don’t pay for a whole new liner when one fitting failed.
- DuraFlex SW (the smooth-wall line) is prone to fly-ash adhesion in pellet stove installs. Pellet exhaust is sticky and alkaline. On smooth-wall liners, the ash clings in a hard crust that a standard brush skates right over. Fix: we use a rotary whip for pellet-specific crust, then run a camera to confirm the smooth wall hasn’t been gouged by previous aggressive cleaning. Gouges in a smooth-wall liner become future ash anchors, so we document them and tell you honestly whether the liner still has life or is heading for replacement.
- DuraFlex rain caps and termination kits loosen in Annapolis wind. The houses along Spa Creek and the Severn get real wind off the water, and a loose cap is the start of water entry and animal entry. Squirrels in the flue are not a hypothetical here. Fix: every sweep includes a termination inspection. We reseat loose caps, tighten the clamp band, and verify the screen isn’t rusted through. A missing screen is a $40 fix now or a $400 removal call later when a raccoon has set up residence.
- DuraFlex oval-to-round adapters are the most common source of smoke smell in upstairs bedrooms. When a liner is ovalized to fit an older Annapolis terra cotta flue, the adapter joint is where it leaks. Smoke and carbon monoxide follow the path of least resistance, and that joint is often it. Fix: we drop the camera, find the leak, and seal the adapter with high-temp sealant rated for stainless liners. This is warranty-safe work - we’re not modifying the liner, just correcting the joint.
Our DuraFlex Chimney Cleaning & Sweep Process
- 1
You call. A live person answers, 24/7. We ask what you burn, how often, and when you last had the flue looked at. You get a firm price before anyone sets foot on your property.
- 2
We arrive and lay eyes on the setup. Wendell or one of his crew shows up in uniform, at the window you were given. We inspect the firebox, the appliance connection, and the termination cap before we touch a brush.
- 3
We measure and select the brush. DuraFlex liners are sized by diameter, and using the wrong brush on corrugated stainless does more harm than good. No generic hardware-store brush on a 6-inch liner. We match the brush to the liner.
- 4
We sweep and remove the creosote and soot. Tarps go down, the vacuum runs HEPA, and we brush the full length of the liner. For heavy glaze, we use a rotary treatment appropriate to stainless, never a chemical that eats the liner.
- 5
We run the camera. Before we call it done, you see the footage. We walk you through what’s clean, what’s worn, and what can wait. No camera, no verdict - that’s the rule.
- 6
You get the report and the guarantee. The price we quoted is the price on the invoice. And the 90-Day Done Right Promise is in writing: if it’s not right, one call brings us back at no charge.
What DuraFlex Chimney Cleaning & Sweep Costs in Annapolis
Straight talk on numbers:
- Standard annual sweep with camera inspection: $189-$289 depending on liner length, creosote stage, and when you last had it cleaned.
- Heavy creosote removal (glazed third-degree buildup): $325-$475. This takes rotary treatment and extra passes.
- DuraFlex tee replacement or cap reseating during a sweep: $85-$220 in parts and labor, and we show you the failed part before we replace it.
- Free second opinion on any written estimate from another company. Bring us the paper, and we’ll tell you honestly if that repair is real or if someone’s padding the invoice.
What moves the price: access (steep roofs and three-story Annapolis colonials cost more to work on), creosote stage, and whether the liner needs a fitting replaced while we’re in there. Seniors and veterans get 10% off, always. No trip charge inside the county. Call (240) 851-3653 for a firm quote.

FAQs
No, regular cleaning and inspection is required by DuraFlex’s warranty terms, and our process is warranty-safe. We use poly brushes and rotary treatments sized to your specific liner diameter and profile. We never use chemical cleaners on stainless liners unless the manufacturer rates them for that liner, because the wrong chemical can pit 316L stainless and quietly ruin a liner that should have lasted twenty years. As an independent DuraFlex service provider, we’re not authorized by DuraFlex, but we install and service their products regularly, and we know what their warranty language actually requires you to do.
Once a year, burn or no burn. Chimneys break in the off-season too, and Annapolis humidity and salt air don’t stop at your front door. If you burn more than two cords a year, or burn green wood, sweep twice a year. The rule holds for every liner brand: first-degree creosote is a brush job, third-degree is a glaze - catch it early.
Yes, and we’ll show you the camera footage to prove it. We look for pitting at the tee, wall thinning at the corrugation peaks, seam separation at adapter joints, and rust staining at the termination. We’ll give you a straight answer: clean it and keep going, or replace it before it becomes a carbon monoxide problem. We don’t manufacture urgency that isn’t there.
Both, and we’ll tell you which is going on your chimney and why. For tees, caps, and termination kits, DuraFlex OEM parts fit correctly and keep the liner system consistent. For some adapters and connectors, quality aftermarket stainless parts do the job at a lower price than OEM markup. We don’t pad your invoice with OEM parts where an aftermarket piece serves just as well. The failed part you can hold in your hand before you pay for the replacement.
We schedule sweeps year-round, and outside the October-to-December rush we can usually get to you within a week. During burn season, expect a longer wait for routine cleaning, but we keep emergency slots for active smoke issues, water leaks, or animal entry. Call (240) 851-3653 and you’ll talk to a person, not a voicemail box. We’ll give you a real arrival window, and if it slips, we call you before you have to call us.
