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 Centennial, CO
We provide independent DuraFlex service across Centennial, from the original 1970s and 1980s prefab flues along the 80111 corridor to modern stainless liner systems in newer builds. DuraFlex makes a flexible stainless steel chimney liner, and a chimney is only as safe as the parts around that liner: the cap, the crown, the top plate, the joints. That’s the difference in how we work here. We don’t just sweep the flue and hand you a report. We inspect the whole system, tell you what’s actually failed, and fix it in the same visit.
Our technicians have up to 15 years of experience with flexible liner systems, and we’re fully licensed and insured. To book your DuraFlex chimney cleaning in Centennial, call (833) 749-6226. We answer 24/7. Fast dispatch from 7am to 7pm, Sunday through Friday.
Why Centennial Residents Choose Us for DuraFlex Service
We know how DuraFlex systems age in Centennial’s climate. The long heating season builds creosote fast, and the spring hail that rolls through the south metro does real damage to caps and crowns up top. When we open a chase or pull a cap, we know what we’re looking at before we start.
We’re an independent shop, not affiliated with DuraFlex or authorized by them. That independence matters. We have no reason to recommend a full reline when a new cap and crown repair will solve the problem. We use DuraFlex-compatible OEM or listed aftermarket caps, top plates, and liner components when they match your existing system. A generic cap or an unlisted adapter on a factory-built flue is a false economy, and we won’t install one to save a few dollars.
Scheduling is straightforward. We book a sweep, show up when we say we will, and give you a written estimate before any repair work begins.

Common DuraFlex Chimney Cleaning Problems We Solve in Centennial
- Cottonwood seed and storm debris packing the spark arrestor. After a July hailstorm knocks a multi-flue cap loose or dents it, cottonwood fluff and debris pack into the arrestor screen. The result is restricted draft and, often, pests finding their way in. We clear the screen, straighten or replace the cap, and check that the arrestor is doing its job.
- Cracked mortar crowns letting water track down the liner. Centennial’s freeze-thaw cycles work on cracked crowns all winter. Water runs down the outside of a DuraFlex liner, then expands and contracts at the top plate and joints. We repair or coat the crown and reseal the top plate before that water does more damage.
- Rusted or seized dampers on older DuraFlex-equipped fireplaces. Long Front Range heating seasons and dry, high-altitude air take a toll on dampers and firebox panels in masonry fireplaces from the 1970s through the 1990s. A seized damper means you can’t control the burn, which wastes heat and builds creosote faster. We free, repair, or replace it.
- Separated or misaligned flexible liner sections in original prefab chases. In 1970s and 1980s prefab chases, liner joints can separate after decades of heating and cooling. This usually turns up during a Level 2 inspection after a homeowner reports a draft complaint or water staining. We confirm the joints, reseat them where possible, and tell you honestly if a section needs replacement.
- Corrosion at the liner top plate and cap connection. Hail season is hard on the hardware up top. Dented caps, loose top plates, and corrosion at the connection point all let water in and draft out. We replace the failing parts with listed components that fit the system.
DuraFlex Service in Centennial: What Local Conditions Mean for Your Equipment
Much of Centennial’s 80111 housing went up between the 1970s and the 1990s as two-story and split-level suburban homes, many with original masonry fireplaces and wood-burning inserts or, in newer builds, factory-built metal flues. That matters for DuraFlex owners because it means a large share of the systems we see are original factory-built flues now at the age where the top plate, storm cap, and flexible liner joints tend to fail together, often after a single hail season. A homeowner in an older 80111 subdivision might notice draft problems or water staining after a spring storm and assume the liner itself has failed. What we usually find is a dented or dislodged multi-flue cap with cottonwood seed packed into the arrestor and a hairline-cracked concrete crown letting meltwater run down the liner. The fix is often a new listed cap, crown repair or coating, and a Level 2 inspection to confirm the liner joints and top plate are still sealed, followed by a sweep and waterproofing to keep the next storm from repeating the pattern. Matching the symptom to the right service is the whole job. For a deeper look at how we handle flexible liner systems, see our DuraFlex service page.
DuraFlex Models & Products We Service in Centennial
We service the full range of DuraFlex flexible stainless steel liner systems in use around Centennial, including round and oval flexible chimney liners, direct vent and factory-built chimney systems, masonry fireplace insert liner kits, and insulated flexible liner assemblies. Each type has its own failure patterns and its own part requirements.
When a part needs replacing, we match it to the existing system. Caps, top plates, and liner components are selected to fit the specific flue, not swapped in from whatever’s on hand. Unlisted adapters and generic caps on factory-built flues are a recurring source of draft problems and water intrusion, and we don’t install them. We also offer HeatShield liner resurfacing when a damaged flue can be restored without a full liner replacement, and we’ll tell you plainly when that option applies and when it doesn’t.

AfterDuraFlex Service Pricing in Centennial
Pricing for a DuraFlex job in Centennial depends on what the inspection finds: a straightforward sweep and cap replacement sits at the low end, while crown repair, liner joint work, or a Level 2 inspection adds cost. We give a written, flat-price estimate before any work begins, so you know the number before we start.
- Chimney sweep with inspection: estimated based on flue count and access, quoted in writing before the visit.
- Cap replacement: estimated per system, including the listed cap and hardware.
- Crown repair or coating: estimated based on crown size and condition.
- Level 2 inspection: estimated per system, including a photo report.
Nothing gets added to the bill without your approval, and nothing gets recommended that you can’t see for yourself in the inspection photos. Call (833) 749-6226 for a free estimate.

FAQs – DuraFlex Chimney Cleaning in Centennial
A dented cap is usually replaced rather than repaired, because a dent distorts the draft path and can loosen the arrestor screen. We inspect the cap, top plate, and crown together, since hail damage often hits all three. If the cap is only slightly bent and the screen is intact, we may be able to straighten it, but replacement with a listed cap is often the more reliable fix. Call (833) 749-6226 for an exact quote; estimates are free.
The most reliable way to know is a Level 2 inspection, which lets us see the full length of the liner and check each joint. Signs that point to separation include draft problems, water staining near the top plate, and visible gaps during inspection. We confirm the joints and tell you whether reseating or section replacement is needed. Call (833) 749-6226 to book an inspection.
Cottonwood seed packs into the spark arrestor screen because the screen mesh catches the fluff, and Centennial’s mature suburban trees put out a lot of it. A screen that’s too fine or a cap that’s been knocked loose by hail makes it worse. We clear the screen, check the cap for hail damage, and replace it with a listed cap with an appropriate mesh size if needed. Call (833) 749-6226 for a quote.
Crown repair is usually enough when the crown is cracked but the brick and liner below it are sound. Repointing, crown coating, and cap replacement solve most Centennial DuraFlex calls. A full rebuild is reserved for genuinely failed sections, and we’ll show you the photos that support either recommendation. Call (833) 749-6226 for an exact quote; estimates are free.
We service DuraFlex gas fireplace inserts and wood-burning systems both, along with direct vent and factory-built chimney systems. The inspection and cleaning approach differs by system type, but the safety checks, cap and crown inspection, and joint verification apply across the board. Call (833) 749-6226 to book service.
