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.
DuraFlex Chimney Cleaning & Sweep in Woodland Park: What to Know First
We clean and sweep DuraFlex chimney systems in Woodland Park, and we do it as an independent DuraFlex service provider, meaning we answer to you, not a manufacturer’s rep. Most DuraFlex cleanings in Woodland Park take under two hours door to door, and you’ll have a written price before a single brush goes up the flue. If your liner doesn’t need sweeping, we’ll tell you that first and save you the trip charge if you’re inside Passaic County.

This page is for Woodland Park homeowners who own a DuraFlex liner or chimney system and want to know what cleaning actually involves, what it should cost, and what can go wrong if it’s ignored. If you’ve got creosote you can see or smell, or you haven’t had the flue looked at in over a year, call (973) 846-1622 and ask for Wendell.
How DuraFlex Products Fail - and How We Fix Them
DuraFlex makes a solid liner. But no liner is a set-it-and-forget-it product, and after enough Woodland Park winters, we see the same handful of issues show up at this elevation and humidity. Here’s what actually happens:
- DuraFlex 304L and 316L liner surface pitting from acidic condensate. Woodland Park gets real temperature swings, and a liner that runs cold on the exterior wall collects acidic moisture, which eats at the inner wall. When we sweep these, we’re checking for pinholes and thin spots, not just brushing soot. The fix depends on what the camera shows: sometimes a cleaning and a cap adjustment solves it, sometimes the liner needs a section replaced before it becomes a carbon monoxide path.
- DuraFlex Smooth Wall creosote loading that a standard brush won’t fully clear. The Smooth Wall series has a slick interior, but “smooth” doesn’t mean “nothing sticks.” Second-degree creosote can still glaze onto it, and if someone has been burning unseasoned wood, you’ll get tar-like buildup that a flat wire brush just glazes over. We use the right brush for the job and let the camera verify it’s actually clean before we call it done.
- DuraFlex Aluminum liner seams separating at the pop-rivet points. This one shows up more on older installations, especially where the liner was pulled tight around an offset. You’ll see soot staining at the seams, which tells us the liner’s no longer a continuous flue path. On a cleaning job we flag it, show you the camera still, and you decide whether it’s a repair or a replace. We won’t push a liner job that isn’t there.
- DuraFlex Pro connection bands slipping after thermal cycling. Every heat cycle expands the liner, and over a few seasons the connection bands can walk a little. When that happens, the joint opens a hair and exhaust starts leaking inside the chase. A sweep and inspection will catch it, because we’re looking at every joint with the camera, not just the big obvious stuff.
- Insulation wrap sagging and letting the liner run too cool. Insulated DuraFlex liners rely on the wrap staying put. When it sags or pulls away, the flue gases cool too fast, which means more creosote and a liner that drafts poorly. A good cleaning is also a good time to have the wrap re-secured, because the liner will just load up again if we don’t fix the underlying problem.
Our DuraFlex Chimney Cleaning & Sweep Process
Every job follows the same order, and nothing gets skipped just because it’s a “simple cleaning.” Here’s what a DuraFlex sweep looks like when we do it:
- 1
You call, and a person answers. Wendell or one of the crew picks up, asks where you are in Woodland Park, and books the appointment right then.
- 2
We show up in a real window, in uniform, with drop cloths and a plan. Before anything comes off the truck, you get the price and we shake on it. The number you hear is the number on the invoice.
- 3
The flue gets inspected before it gets swept. Camera down the stack, looking for the DuraFlex-specific issues above: pitting, thin spots, separated seams, slipped bands, sagging insulation. You see the footage.
- 4
We sweep with the right brush for your liner and your creosote load. First-degree creosote is a brush job. Third-degree is a glaze. We match the tool to the problem, not the other way around.
- 5
Camera again after the sweep. You see clean flue walls on the screen before we pack up. If something still looks wrong, we stop and tell you.
- 6
You get a plain-English report and the 90-Day Done Right Promise in writing. If the sweep wasn’t thorough or we missed something that should have been caught, one call brings us back at no charge.
What DuraFlex Chimney Cleaning & Sweep Costs in Woodland Park

Why Woodland Park Homeowners Call Top Hat Chimney for DuraFlex Work
Wendell Pike started Top Hat Chimney in 1999, and he’s been in more Woodland Park flues since then than he can count and a fair few over by Rifle Camp Park. He’ll tell you straight: your flue doesn’t care how the fire looks. It cares how it breathes. That’s why every DuraFlex job gets the camera, and the camera footage comes with a plain-English verdict. If it doesn’t need doing, Wendell will tell you that first.
We work on DuraFlex, HeatShield, Gelco, and a handful of other systems, so we’re not married to one product line and we won’t try to sell you a liner you don’t need. Every job carries the 90-Day Done Right Promise in writing. Seniors and veterans save 10% every day. And when you call, a live person answers, around the clock. No voicemail box. No call center. Sometimes it’s Wendell himself, which is how it’s been for over 29 years.
FAQs
No. In fact, skipping annual cleaning is one of the fastest ways to have a warranty claim denied, because creosote buildup and clogged flues are considered maintenance failures, not manufacturing defects. What can void your DuraFlex warranty is using the wrong cleaning method or a brush that scores the liner. We sweep DuraFlex systems with brushes matched to the liner material and creosote stage, and we keep records of every job, which matters if you ever need to file a claim. Call (973) 846-1622 and we’ll walk you through what your specific liner is rated for.
Once a year, burn or no burn. Chimneys break in the off-season too, and a Woodland Park summer with humidity and temperature swings can work on a liner just as surely as a January fire. If you burn every weekend or you burn wood that isn’t fully seasoned, twice a year is smarter. The rule is simple: sweep it before the creosote gets to the stage where a brush can’t handle it.
You can sweep without one. But on a DuraFlex liner, the sweep without the camera is half a job. The camera is the only way to see the pinholes, thinned walls, and seam separation that a brush won’t catch and that your eyes can’t reach. We don’t charge extra for the camera on a standard sweep. You get the footage and the verdict either way.
Most of the time, we can get a crew to your house within a few days, and if you’ve got a burning season bearing down on you, we do our best to work you in sooner. We don’t promise same-day service and we won’t rush the job. But a scheduled sweep is usually done within a week of your call, and if something slips, we call you.
Depends on what the camera shows. A slipped connection band, sagging insulation, or a minor seam issue can often be repaired without a full liner replacement. If the liner is pitted through or the seams are open in multiple places, you’re looking at a replace. We’ll show you the footage and tell you straight if it can safely wait. If you’ve got a written estimate from another company, bring it in and we’ll give you a free second opinion. Call (973) 846-1622 to set that up.
