Gelco Chimney Cleaning in Liberty Hill, TX | Boardwalk Chimney Sweep
Boardwalk Chimney Sweep provides independent Gelco chimney cleaning and inspection across Liberty Hill, TX. We work on Gelco factory-built metal chimney systems in both the older ranch houses with wood stoves and the newer custom homes going up around town. The thing that makes our Gelco work different here is what a rushed sweep misses: corrosion at the flue collar, failing caps, and creosote that hardened over a Liberty Hill summer. Call (877) 274-1247 for an estimate.
Why Liberty Hill Residents Choose Us for Gelco Service
Gelco chimneys are straightforward systems, but they don’t all age the same way. A metal flue on a 1980s ranch house off Highway 29 sees different stress than one on a five-year-old build in Santa Rita Ranch. We’ve worked on both. Brent Holloway, our owner, came up through the HVAC and building systems program at Austin Community College’s Riverside Campus and spent years on Hill Country roofs before starting Boardwalk. He’s the one who trained our crew to look for the failure points other sweeps gloss over: rust at the joints, loose caps, dampers that never got adjusted. For Gelco sales & service, that depth matters because the parts you don’t inspect are the ones that fail first. We’re local to the Liberty Hill area and familiar with how these systems behave in our specific climate. That’s the advantage of hiring someone who actually knows the housing stock here, not just the brand name.

Common Gelco Chimney Cleaning Problems We Solve in Liberty Hill
- Corrosion and rust-through on metal chimney sections. Liberty Hill’s occasional freezes and wind-driven rain push moisture into Gelco flue joints. Once rust starts at a seam, it spreads quietly. We find this most often on exposed chimney runs on older ranch homes.
- Loose or cracked Gelco chimney caps. A cracked cap lets water drip straight down the flue and gives squirrels and birds an entry point. In Liberty Hill’s spring and fall, nesting activity spikes hard. We replace damaged Gelco caps before animals turn your flue into a den.
- Hardened creosote in Gelco metal flues. Liberty Hill’s hot summers bake creosote into a hard, glassy layer during the off-season. It doesn’t brush out easily once it’s glazed. Older wood stoves on acreage properties are the worst offenders, and this buildup is a chimney fire waiting for a cold snap.
- Dampers and components that stuck from disuse. Homes that never had a professional cleaning often have dampers rusted open or seized shut. We free them, lubricate, and replace components when necessary during the same visit.
- Water intrusion through failed flashing at the roofline. Liberty Hill’s clay-heavy soil settles, and older homes shift. That movement breaks the seal where the Gelco chimney meets the roof. We identify the leak during the sweep and address it before it rots framing.
Gelco Service in Liberty Hill: What Local Conditions Mean for Your Equipment
In Liberty Hill’s older ranch properties, original clay tile liners often crack from decades of heating and cooling cycles. Homeowners usually learn about that after a chimney fire or a failed inspection. But here’s the detail that gets missed: the same homes frequently have Gelco metal chimney systems installed alongside or in place of the original masonry, and those metal flues carry their own hidden failure point. The joints. Gelco sections are press-fit and sealed, and after enough seasons of Texas heat and those occasional hard freezes we get in Hill Country winters, the sealant degrades. Moisture gets into the joint, rust forms, and you end up with pinholes that would never show up in a basic visual check. A Level 2 inspection with a camera finds them. Most sweep-and-go services skip that step. We don’t, because on a ranch property with a working wood stove, a corroded Gelco joint is a fire hazard and a carbon monoxide risk at the same time. If you can smell the smoke inside, the chimney’s already telling you something, worth listening before it gets louder.
Gelco Models & Products We Service in Liberty Hill
We service Gelco factory-built metal chimney systems used with wood stoves and fireplaces, along with Gelco chimney caps and multi-flue caps. When a repair comes up, we source OEM Gelco components for safety-critical parts like caps and flue sections. If OEM is discontinued or priced unreasonably, we’ll tell you and offer a quality aftermarket equivalent instead, always naming what we’re using and why. We stock common Gelco cap sizes locally for faster Gelco service in Cedar Park turnaround, and uncommon parts we order in. The honest read on repair versus replace is part of every estimate: if your Gelco system has widespread corrosion, replacement is usually the safer and cheaper long-term move than patching one section at a time.

AfterGelco Service Pricing in Liberty Hill
Liberty Hill Gelco chimney cleaning and inspection typically runs from $180 to $350 depending on flue condition, roof access, and whether your system needs a standard sweep or a full Level 2 camera inspection. Cap replacements add parts cost, and we’ll quote the OEM and aftermarket options up front so you choose with the numbers in front of you. The estimate is free and it’s specific to your house, not a menu price. What drives cost here is creosote hardness after a hot Liberty Hill summer, roof pitch on two-story custom builds, and whether animals left debris that has to be removed before cleaning. Call (877) 274-1247 and we’ll give you an exact number. No pressure.

FAQs – Gelco Chimney Cleaning in Liberty Hill
Expect a thorough inspection before any brushing starts. On a never-maintained system we check the cap, the flue collar, the damper, and the exposed chimney sections first. If we find creosote glazing or corrosion, we’ll show you photos before we proceed. First cleanings on old ranch homes often run longer because the creosote has hardened through multiple Liberty Hill summers.
The heat bakes creosote into a hard, tar-like glaze during the off-season. A standard brush won’t fully remove glazed creosote, so we use rotary cleaning tools when needed. The mild winter then fires the stove heavily for a few short months, layering new creosote on top of the old. That’s why annual cleaning matters more here than in places with longer burn seasons.
Yes. We source OEM Gelco caps when available and stock the common sizes locally for faster Liberty Hill service. If OEM is discontinued, we’ll offer a quality aftermarket equivalent and explain the difference in material and fit before any work happens. Call (877) 274-1247 and we’ll identify the cap you need.
A Level 1 is a visual inspection of the accessible portions of the chimney and flue. A Level 2 adds camera scanning of the interior flue and access to the attic, crawlspace, and roof areas. For Gelco in Leander and older Liberty Hill ranch homes, we recommend Level 2 because hidden corrosion at the joints won’t show up in a basic visual check.
We service the Gelco chimney systems connected to wood stove inserts, including the flue, cap, and connection points. We don’t service the appliance itself beyond the chimney side of the connection. If your Liberty Hill home has a wood stove insert that’s been worked hard through winter, call (877) 274-1247 and we’ll check the entire flue path.
