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 Apex, NC
We provide independent DuraFlex service across Apex, and the thing that sets our work apart here is that we diagnose your flue before we recommend parts, not after. DuraFlex is a flexible stainless steel chimney liner, and in Apex’s mix of 1990s clay-tile chimneys and newer prefab builds, the way those liners fail is rarely the same twice. We are not affiliated with or authorized by DuraFlex. We’re a chimney shop that knows the product and fixes what’s actually wrong.
Why Apex Residents Choose Us for DuraFlex Service
We’ve been sweeping and repairing DuraFlex chimney systems across the Triangle since these liners were going into 1990s and 2000s Apex builds. That matters. We’ve seen their stainless inner-wall and insulation behavior firsthand, through years of humid summers and hard cold snaps, and we know where the seams tend to give out in this climate. Because we’re independent, we don’t work from a factory script.
We figure out what your flue needs and source parts to match. Sometimes that’s a full DuraFlex reline. Sometimes it’s a resealed top plate and a re-wrapped liner section. Raleigh Chimney Cleaning has called Apex home for this work since 2013, and Greg Hanson, our owner, has spent most of his adult life on Triangle chimneys. He grew up in Raleigh’s Mordecai neighborhood, trained in building construction technology at Wake Technical Community College, and spent well over a decade in the trade before he started this company. That background shapes how we look at a flue: we check the whole system, not just the firebox.

Common DuraFlex Chimney Cleaning Problems We Solve in Apex
Here’s what we actually find on DuraFlex systems around Apex:
- Liner seams and collar joints loosening. Repeated heat-cool cycling works on the seams and collar joints in DuraFlex liners until they start to open. Once they do, creosote and moisture migrate into the insulation wrap. Apex fires run in intermittent bursts through cold snaps, then sit idle for months, and that swing accelerates the cycle. We check seams at every sweep, not just the visible run.
- Insulation wrap compression or tearing in clay flues. When a DuraFlex liner gets pulled through a clay flue with rough or cracked tile, the insulation wrap can compress or tear. In ZIP 27502’s 1990s clay-tile chimneys that’s a common call. A torn wrap means the liner loses its protection against the masonry and against heat, and it’s something a standard sweep won’t catch.
- Top-plate and cap sealing failures. Apex’s summer humidity and driving rain wick down between the liner and the masonry when the top plate or cap seal fails. The sealant dries, cracks, and pulls away. Water gets in, insulation gets saturated, and you end up with a chimney that smells even when it hasn’t been used in months. We check the seal from the rooftop on every service.
- Liner separation at the appliance connector. Many Apex homes were remodeled in the 2010s and 2020s, and we regularly find a wood-burning insert retrofitted into a prefab firebox. When that happens, the liner-to-connector connection can work loose. That’s a fire and gas-escape risk, and it’s not visible from inside the firebox.
- Creosote buildup no one noticed. Annual burning during a few weeks of cold weather leaves more creosote than people expect. On DuraFlex systems, that buildup settles into the seam areas and the liner texture where brushes have to reach to actually remove it. A proper sweep and camera check tells you what’s really in there.
DuraFlex Service in Apex: What Local Conditions Mean for Your Equipment
Here’s the local fact that shapes almost every DuraFlex call we take in Apex. In the older core around Laura Duncan Road and the surrounding 27502 streets, many chimneys were built through the 1990s with clay flue tiles that crack after a freeze-thaw event. Homeowners often notice that crack as a smoky smell in summer, not during a fire. On a DuraFlex-lined flue, that means the crack can press against the liner’s insulation wrap long before you’d ever think to call someone. So we scope from the rooftop even when the sweep comes back clean. On one 1998 brick home off Laura Duncan Road, the owner called in July about a smoky odor. Our tech found a cracked clay tile pressing against the DuraFlex insulated liner, with the top-plate sealant dried and pulling away. We pulled the liner, replaced the damaged tile section, re-wrapped and re-seated the liner, sealed a new top plate, and waterproofed the crown. The smell was gone before the first fall fire. That’s the sequence: rooftop scope first, then the fix. If you don’t know what’s in your flue, you don’t really know what’s heating your house.
DuraFlex Models & Products We Service in Apex
We service the DuraFlex flexible stainless liner systems common in Apex homes, including the Pro stainless flexible relining kit, the Standard single-wall flexible liner, the Insulated flexible liner used on exterior masonry chimneys, and the Pro-Flex smooth-wall liner. We use DuraFlex OEM liner sections, top plates, and caps when your existing system is still serviceable. When a full DuraFlex replacement isn’t warranted, we use quality aftermarket stainless connectors that fit properly. We don’t carry a big-box substitute and call it close enough. The parts either match your system or they don’t.
To talk through what system you have, DuraFlex service starts with an inspection. Call (833) 304-2125.

AfterDuraFlex Service Pricing in Apex
What drives cost on a DuraFlex job in Apex: the line condition, the number of stories, liner length, whether the insulation wrap and top plate need replacement, and whether we’re reseating an existing liner or installing a new one. Sweeping, creosote removal, and a Level 2 inspection start at typical area rates, and any repair is priced separately so you can decide. We give you a written estimate before any work begins. The written estimate sets the final price. There’s no fee for the estimate itself, and nothing gets recommended without camera evidence you can see for yourself. Chimney Waterproofing on the crown and masonry is often quoted alongside liner work when we find moisture intrusion, but it’s a separate decision.
To get an exact number for your Apex chimney, call (833) 304-2125. We answer 24/7. Fast dispatch from 7am to 7pm, Sunday through Friday.

FAQs – DuraFlex Chimney Cleaning in Apex
No. Raleigh Chimney Cleaning is an independent DuraFlex service provider. We are not manufacturer-affiliated, authorized, or sponsored by DuraFlex. That independence is why we can diagnose your flue and recommend the parts it actually needs, rather than working from a single-product playbook.
We use DuraFlex OEM liner sections, top plates, and caps when the original system is still serviceable. When a full DuraFlex replacement isn’t warranted, we use quality aftermarket stainless connectors that fit properly. Our stance: reline and reseal when the liner integrity holds; replace the whole system only when the inner wall is perforated or the insulation is saturated.
A Level 1 inspection covers the readily accessible parts of the chimney and firebox without special tools; a Level 2 inspection goes further and includes the flue interior, typically with a camera, and is what you want when there’s a liner, a change in the system, or a suspected problem. On Apex’s clay-tile chimneys, we scope from the rooftop and use camera inspection, so you’ll usually see a Level 2-level check on any DuraFlex flue we service.
A standard sweep and inspection usually takes about an hour to ninety minutes depending on the system and how much buildup there is. If we find a problem and you approve repair work, we’ll give you a time estimate in the written estimate. Same-day scheduling is often possible.
Sweeping and inspection start at typical area rates, and repair or reseating work is priced separately based on what we find. The estimate is free and the written estimate sets the final price. Call (833) 304-2125 for an exact quote.
