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 in Lakewood, CO
We provide independent DuraFlex service across Lakewood, and what sets our work apart here is that we know exactly how these liners behave inside this city’s mid-century exterior brick chimneys after years of freeze-thaw. DuraFlex is a flexible stainless steel chimney liner, and cleaning one properly means inspecting it, not just brushing it. Our technicians have up to 14 years of experience, and we handle the sweep, the inspection and any repair on the same visit so nothing gets handed off. Call (888) 320-6023 for a free estimate.
Why Lakewood Residents Choose Us for DuraFlex Service
We work with a curated roster of professional-grade brands, and DuraFlex is one of them. That matters because a flexible liner is a system, not a tube. The top plate, the cap, the support brackets and the appliance connector all have to fit the liner that’s already in your chase, and generic universal parts don’t always do that.
We’re an independent shop. We’re not affiliated with DuraFlex and we’re not a dealer, so our recommendation comes from what your flue actually needs, not from what we’re supposed to move. When a liner has years of life left, we clean it, re-seat the connections and re-seal the top. When it’s pitted or the insulation is gone, we tell you that too.
Scheduling is straightforward. You get a window, a written estimate before any work, and one point of contact from the sweep through the repair. That’s how we prefer to run it, and it’s why homeowners around Lakewood keep calling back.

Common DuraFlex Chimney Cleaning Problems We Solve in Lakewood
- Top-plate and cap seals failing. The seal at the top of a flexible liner takes everything the Front Range throws at it. UV breaks down the sealant over time and freeze-thaw works it loose, so snowmelt runs down into the annular space and starts corroding the liner or the appliance collar. We re-seal and replace caps as part of the service.
- Insulation shedding at elbows. Insulated liners in exterior masonry chases can lose wrap or insulation at the bends. In Lakewood’s long cold-burn cycles that shows up as condensation and glazed creosote, which is harder to sweep and needs to be seen on camera to be removed properly.
- Loosened twist-lock and slip joints. Years of heating and cooling work these connections loose or slightly out of line. Creosote collects right at the joint, and a basic sweep from the top can miss it entirely. A Level 2 camera inspection is how you find it.
- Unsupported liners in oversized flues. Mid-century brick chimneys often have a flue opening much wider than the liner running through it. Without proper top support the liner can rub, kink at an offset or sit off-center, and that’s a re-seating job before it becomes a replacement job.
- Glazed creosote from cordwood burning. Homes that heat with wood through a cold winter build creosote in layers, and the third-degree glaze doesn’t come off with a brush alone. It needs proper removal, and it’s the single biggest reason a DuraFlex liner in Lakewood needs attention before the next burning season.
DuraFlex Service in Lakewood: What Local Conditions Mean for Your Equipment
Here’s the local detail that shapes nearly every DuraFlex job we see in Lakewood. Around Eiber and Belmar, the 1950s and 1960s ranches have exterior brick chimneys with original clay flues that were sized for a fireplace, not for the wood stove or insert many owners added later. Those flues are too narrow for the new appliance, so a flexible liner was retrofitted inside the old masonry to make it work. The trouble is that the original narrow clay hides the liner. You can’t see the condition of the stainless from the top, and you can’t see it from the firebox either. That’s why a camera inspection is often the difference between a routine sweep and discovering a joint that’s been collecting creosote for years. Decades of freeze-thaw on those same Belmar and Eiber exterior chimneys add cracked crowns and spalling brick, which lets moisture in behind the liner.
DuraFlex Models & Products We Service in Lakewood
We service the full range of DuraFlex flexible liner systems in Lakewood, including flexible relining kits, professional flexible liner systems, factory-insulated liner kits and rigid stainless reline sections used in masonry chases. Each one has its own cleaning considerations. Insulated liners need their wrap checked, not just their interior brushed. Rigid reline sections need their joints looked at. Flexible kits need the top support and connector verified.
Because DuraFlex is a proprietary system, replacement components should be genuine DuraFlex parts or the manufacturer’s specified equivalents rather than generic universal pieces. We choose parts that fit the liner that’s already installed in your Lakewood home, and we tell you plainly when a component can be re-sealed instead of replaced.

AfterDuraFlex Service Pricing in Lakewood
Pricing is set per job by a written estimate. A few things drive the number: whether your liner is flexible or rigid, how accessible the top plate and cap are, whether the chimney is an interior or exterior chase, how much glazed creosote needs removal, and whether a Level 2 inspection is required to see the liner’s condition at the joints.
| Service | What it covers |
|---|---|
| Chimney sweep | Flue cleaned top to bottom, creosote removed, work area protected |
| Level 2 inspection | Camera inspection of the liner interior, joints checked, top plate and cap assessed |
| Creosote removal | Glazed deposits removed where a standard brush won’t reach |
| Cap and top-plate re-seal | Seals re-done, components replaced where seals have failed |
| Liner re-seating or support repair | Liner re-centered and re-supported in an oversized flue |
The estimate is free and the number you get in writing is the number you pay. Call (888) 320-6023 to book a visit and get an exact quote for your Lakewood home.

FAQs – DuraFlex Chimney Cleaning in Lakewood
Because the original clay flue hides the liner. In a lot of Lakewood’s mid-century ranches the retrofit liner sits inside masonry that’s too narrow to see past, so there’s no way to check the joints, the insulation or the appliance collar from a basic top-down sweep. The Level 2 inspection uses a camera to look at the liner’s interior directly, and that’s how we know whether what we’re cleaning is intact. Call (888) 320-6023 to book one.
It’s common here, but it isn’t normal and it shouldn’t be ignored. Lakewood’s freeze-thaw winters break down top-plate seals over time, and once water gets in behind the liner it runs down to the firebox and starts corroding the stainless. Re-sealing the top plate and checking the cap is usually the fix, and it’s far less than a reline. Call (888) 320-6023 for an estimate.
Yes. Glazed creosote is harder to remove than the fluffy kind, but a flexible stainless liner can be cleaned properly with the right tools for the job, and sometimes a chemical treatment first. It doesn’t mean the liner has to be replaced. It does mean the sweep takes longer and the liner gets inspected after, to confirm nothing underneath was affected. Call (888) 320-6023 to get it looked at.
They can. The Front Range wood-burning rules from the 2010s and the requirements many insurers now place on wood-burning appliances both affect what you can burn and whether your setup is compliant. A DuraFlex liner is part of that picture. We’ll tell you what we see on inspection, and for the regulatory side we suggest checking with the city or your insurer directly. Call (888) 320-6023 to book an inspection.
It can, yes. Spalling brick and a cracked crown let moisture into the chimney structure, and once water gets behind the liner it can reach the insulation or the stainless itself. That’s why we look at the outside of the chimney as well as the inside when we’re servicing a DuraFlex liner in Lakewood. Sometimes the liner is fine and the crown needs attention. Call (888) 320-6023 for a free estimate.
