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 Lakeway, TX | Boardwalk Chimney Sweep
We provide independent DuraFlex chimney cleaning and inspection across Lakeway, including the steep ridge lots and tall exterior chases that define this side of the lake. What makes our DuraFlex work here different is simple: we know where these liners fail on Lakeway homes, because we’ve anchored to enough ridge lines above limestone slopes to map the failure points. If you need a straight answer about your liner’s condition, call Brent Holloway at Boardwalk Chimney Sweep: (877) 274-1247.
Why Lakeway Residents Choose Us for DuraFlex Service
DuraFlex is one of the most spec’d stainless flexible liner systems on Lakeway’s tall exterior chimneys, and we’ve installed, re-seated, and serviced their components across the 78738 hill builds for years. We’re an independent sweep shop, not affiliated with or authorized by DuraFlex, so our call on your liner is based on what we measure inside your flue, not a brand program. That independence matters when a homeowner needs to know whether a liner can be repaired or should be replaced.
Brent Holloway has lived in the Lake Travis Highlands area long enough to remember when half these lakeside neighborhoods were still cedar scrub. He learned the fundamentals through the HVAC and building systems program at Austin Community College’s Riverside Campus, then spent years working every kind of flue you find in the Hill Country: clay-tile liners, stainless inserts, the old double-wall metal systems from the eighties lake house boom. These days he’s the guy neighbors call when they want a straight answer about creosote buildup or whether a prefab firebox can handle another season without a new liner.
We carry DuraFlex factory components, top plates, caps, connectors, and liner sections, so we’re not waiting on a supply house order when your chimney needs attention. The same brands chimney professionals specify. One call, two fire hazards addressed when you bundle a chimney sweep with dryer vent cleaning.

Common DuraFlex Chimney Cleaning Problems We Solve in Lakeway
- Glazed creosote bridging the liner’s corrugations. Lakeway’s hot, dry summers mean fireplaces sit unused for months. Deposits harden into a glaze that clings to the corrugated walls of a DuraFlex liner, restricting draft in vaulted, hard-to-draft chases. We remove it with the right mechanical brushes and solvents, not a quick pass that leaves the glaze behind.
- Crushed or kinked liner sections where the flue jogs around limestone. A lot of Lakeway homes are built on ridge lines and hillsides where masons jogged flues around limestone shelves. Insulated DuraFlex liners can develop crushed or kinked sections at those offsets. We camera the flue to find them before they become a full blockage.
- Top-plate and cap seals baked loose by the sun. Exterior chimneys in Lakeway take direct summer sun and storm-driven rain. Top plates and cap seals expand, contract, and eventually pull loose. That lets rain into the smoke chamber and down the liner. It’s the outdoor end of a DuraFlex system that fails first, and it’s exactly what our ridge-anchored inspections catch.
- Liner-to-appliance connectors loosening on retrofitted fireboxes. On second-story chases where a firebox was retrofitted years after the original flue, the connector between liner and appliance sees a lot of movement. We check those connections on every Level 2 inspection and re-seat them when they’ve shifted.
- Pollen and caliche grit accumulating under a compromised cap. The spring live oak pollen dump in Lakeway is heavy, and caliche dust rides the wind. A loose or damaged cap lets both into the liner, where they mix with creosote into an abrasive paste. We clean the liner and address the cap so it doesn’t happen again next season.
DuraFlex Service in Lakeway: What Local Conditions Mean for Your Equipment
Many Lakeway chimneys sit on rooflines pitched above limestone slopes. A DuraFlex top-plate and cap inspection here often means anchoring to the ridge and rigging down, a fall-risk setup most flat-lot Austin sweeps never train for. It’s exactly where the weather-thrashed outdoor end of a DuraFlex liner fails first.
Take the ridge roads above Lake Travis, off the main DuraFlex service in Barton Creek artery. A few winters back our crew anchored to the ridge to reach a tall exterior chase where the DuraFlex top plate had worked loose after a spring freeze. The cap was letting oak pollen and rain straight into the smoke chamber. We pulled the cap, cleaned the liner’s corrugations of glazed creosote and grit, re-sealed the top plate to the flue tile, and fitted a fresh DuraFlex-compatible multi-flue cap. The owner’s first fire that fall drafted clean instead of puffing into the vaulted room. That’s the kind of thing you only catch when you can actually get to the top of the chimney, and it’s why we bring the rigging.
DuraFlex Models & Products We Service in Lakeway
We service the full DuraFlex in Briarcliff line homeowners around Lakeway commonly have installed: DuraFlex Pro stainless flex liner in both single-wall and insulated configurations, DuraFlex Reline kits for masonry fireplace conversions, and DuraFlex stainless multi-flue and top-mount cap systems.
When parts need replacing, we match DuraFlex factory components rather than generic substitutes. The system’s clearances and UL listing depend on staying within the manufacturer’s parts family. Generic caps and adapters are where we see seals fail, and that failure is predictable enough that we won’t install one. We keep common DuraFlex top plates, caps, and connectors in our local stock, so a repair doesn’t get held up waiting on a parts shipment. For a broader look at the brand, see our DuraFlex sales & service page.

AfterDuraFlex Service Pricing in Lakeway
DuraFlex chimney cleaning in Lakeway typically runs between $180 and $340 for a standard sweep, depending on liner length, access difficulty, and how much glazed creosote has built up. A Level 2 inspection with camera runs higher because we’re documenting the liner’s condition along its full length, and on steep-lot homes the access work is more involved.
What drives cost: the height of the chase, whether we’re anchoring to the ridge or working from a ladder, how much glaze and grit has accumulated, and whether top-end hardware like the cap or top plate needs replacement. A free estimate includes the access assessment and a look at your liner’s history. Call (877) 274-1247 and we’ll give you a straight number before any work is booked.

FAQs – DuraFlex Chimney Cleaning in Lakeway
Because Lakeway’s climate and building stock create failure points a standard sweep won’t catch. The summer heat bakes top-plate seals loose, storm-driven rain works into exterior chases, and limestone-ledged flue offsets crush or kink liner sections. A Level 2 inspection with a camera shows us whether the liner is sound or whether a fix is needed before you burn. Call (877) 274-1247 to schedule one.
Usually, yes. If the liner itself is sound and only the top-end hardware failed, we’ll pull the old cap, inspect the top plate, clean the exposed liner section, and fit a fresh DuraFlex-compatible cap with a proper seal to the flue tile. If the freeze also cracked the crown or shifted the top plate, we’ll address that too before the next rain. Call (877) 274-1247 for a free estimate.
Yes, significantly. Many Lakeway chimneys sit above limestone slopes where we anchor to the ridge and rig down rather than ladder up. That access changes how we inspect the top plate, cap, and upper liner, and it’s why we don’t quote a flat-lot price over the phone for a hill property. We assess the roof pitch and access route before quoting. Call (877) 274-1247 and we’ll come look.
It’s the idle months that do it. Lakeway’s hot, dry summers bake the creosote from those few fires into a hardened glaze that clings to the liner’s corrugations. A light-use fireplace can still develop a serious glaze over time. If you can smell the smoke inside, the chimney’s already telling you something, worth listening before it gets louder. Call (877) 274-1247 to get it cleaned properly.
Yes. We install DuraFlex flexible liner systems, which work well for the offset flue configurations and long runs common in Lakeway homes. We measure the flue, camera it for obstructions, and size the liner to the appliance and flue dimensions, exactly what the UL listing requires. Call (877) 274-1247 and we’ll talk through what your fireplace needs.
