Chimney sweep logs do not sweep chimneys. They loosen some creosote - which then falls where a brush and vacuum still have to collect it.
Why Lubbock Homeowners Choose Gelco Chimney Cleaning
We provide independent Gelco chimney cleaning and service in Lubbock, TX. That means flue sweeps, insert and stove service, creosote removal, and Level 2 inspections on Gelco equipment, done by technicians who work on these units often and know where they fail. We are an independent service provider. We are not affiliated with, authorized by, or endorsed by Gelco, and we don’t sell their products. What we do is clean, diagnose, and repair the Gelco equipment already sitting in Lubbock homes.

Gelco is a chimney cap brand, and a cap is the first line of defense on a High Plains flue. It keeps rain out, and it keeps the grit out too. In Lubbock, that matters more than most places. A cap that’s cracked, loose, or missing lets wind-driven dust straight into the flue, where it settles on dampers and smoke shelves and mixes with soot into a hard, sticky layer that’s slow to sweep and easy to miss on a quick brush-out. Our technicians have up to 12 years of experience, and they treat the cap as part of the chimney, not an accessory bolted on top.

Why Trust Chimney Sweep Lubbock for Your Gelco Chimney Cleaning?
Because we know what a Gelco cap should look like when it’s doing its job, and what it looks like when it’s quietly failing. A cap is a simple piece of equipment, but the failures aren’t always obvious from the ground. A mesh screen packed with cottonfield grit, a crown that’s pulled loose at one corner, a cap sitting a little off-square after a wind event, all of these read as “fine” from the driveway and read very differently from the roof.
We work with quality parts that fit Gelco caps and the flues they sit on. We don’t claim to stock OEM or genuine Gelco parts, and we’re not a Gelco dealer. What we do is source components that meet the same job: a cap that sheds water, screens sparks, and holds up to the wind. When we replace a cap or repair a crown, we choose materials the trade trusts, and we explain why we picked what we picked.
On the rest of the system, we work with trade-trusted brands including DuraFlex and HeatShield. A Gelco cap on top of a flue with a failing liner is a cap doing its job on a chimney that isn’t. We inspect the whole run, not just the part with the name on it, and we tell you plainly when the cap is fine and the problem is further down.
Every job is scoped by a written estimate before we start. Nothing gets recommended without camera evidence you can see for yourself.

Common Gelco Chimney Cleaning Problems We Fix in Lubbock
Lubbock sits in the heart of the dusty, wind-whipped Texas High Plains. Chimney work here is less about ice and more about dust, soot, and the region’s violent spring wind events. The same west wind that erodes topsoil pushes grit and airborne debris down caps and through drafty dampers. That’s why a cleaning appointment in Lubbock should always pair a flue sweep with a wind-driven dust and creosote inspection. Here’s what we find on Gelco caps and the flues beneath them.
- Mesh screen packed with grit and debris. The screen on a Gelco cap is meant to pass smoke and block sparks. After a spring dust storm, it can be half-plugged with red clay topsoil and grit blown in from the surrounding cotton fields. A clogged screen chokes draft, and the fireplace starts smoking back into the room. Sweeping the flue won’t fix it if the screen is still packed.
- Caps loosened or knocked off-square by wind. High Plains wind events put real load on a cap. Mounting legs bend, fasteners work loose, and the cap sits crooked. A cap that’s off-square can let rain run down the wrong side of the flue and let debris in at the gap. We check the seating and the fasteners on every visit.
- Cracked or rusted cap tops and seams. A cap takes the weather head-on. Seams open, the top panel rusts through, and water finds the flue. In a semi-arid climate with hot dry summers and occasional hard freezes, the cycle of heating and cooling works on those seams year after year. A cracked cap top is a slow leak into the smoke chamber.
- Creosote glaze on the flue below a healthy cap. The cap can be perfect and the flue still a problem. Long idle fireplaces between infrequent cold spells let creosote and soot harden into glaze while wind-blown dust and grit collect on dampers, caps, and smoke shelves year-round. Glaze doesn’t brush off with a standard sweep. It needs proper creosote removal, and it’s the reason we inspect rather than just sweep.
- Wrong-size or missing caps on older Lubbock flues. Lubbock is dominated by single-story brick and frame ranch houses built from the 1950s through the 1970s, and many of those older ranches have undersized or uncapped flues that have never been swept since construction. An uncapped flue on a High Plains roof is an open door for dust, rain, and birds. A correctly sized Gelco cap closes it.
Gelco Parts & Our Repair-vs-Replace Approach
We don’t stock OEM or genuine Gelco parts, and we won’t tell you we do. What we do is fit quality parts that do the job a Gelco cap is supposed to do: shed water, screen sparks, and stay put in the wind. When a cap can be re-seated, re-fastened, or have a damaged screen replaced, that’s the first call, because it’s the least invasive fix and it keeps a sound cap in service.
When a cap is cracked through, rusted at the seams, or the wrong size for the flue, replacement is the honest answer. We choose a cap that matches the flue’s actual dimensions and the chimney’s draft needs, not whatever’s on the shelf. Same logic applies further down. A flue with light glazing gets swept and monitored. A flue with a deteriorated liner gets HeatShield resurfacing where the liner can be restored, or a DuraFlex liner where it can’t.
Our rule is simple: repair what’s safely repairable, replace what isn’t, and show you the camera evidence for either call. If a problem can safely wait until next season, we’ll say so.

Our Gelco Service Process – Step by Step
- 1
Diagnosis. We start at the cap and work down. Cap seating, fasteners, screen condition, and crown are checked from the roof, then the flue is swept and camera-inspected. On the High Plains, that inspection always includes looking for grit and dust intrusion at the damper and smoke shelf, not just creosote.
- 2
Repair or install. If the cap needs re-seating, a new screen, or replacement, we do it with quality parts that fit the flue. If the flue needs creosote removal, resurfacing, or relining, we scope that separately in writing before any work starts.
- 3
Test. The cap goes back on square and fastened. We check draft and confirm the flue pulls the way it should before we call the job done. A cap that fits but chokes the draft is a failed install.
- 4
Warranty and documentation. You get a photo report of what we found and what we did, plus the written estimate that set the price. If a part we supplied fails, you call us back. No handoff to a second contractor.

AfterGelco Products We Service & Install in Lubbock
Gelco is a chimney cap brand, and caps are what we service and install. That covers the standard single-flue cap, multi-flue caps for chimneys with more than one flue, and caps sized for the smaller flues common on older Lubbock ranch houses. We handle cap replacement, screen and mesh repair, re-seating after wind damage, and cap sizing when an existing cap is too small or too large for the flue opening.
We don’t service or install anything else under the Gelco name. If your chimney has a Gelco cap and you’re not sure of its condition, that’s exactly what an inspection answers. We also service the flue, firebox, damper, and liner beneath the cap, because a cap is only as good as the chimney it sits on. Renters near the Texas Tech campus often have fireplaces that haven’t been swept since the last tenant moved out, and those are frequently uncapped or fitted with a cap nobody has looked at in years.
We Also Service These Brands
Caps are one part of the system. We also work with DuraFlex liner systems for full relining jobs, and HeatShield for restoring a deteriorating flue liner without full replacement. That multi-brand capability means we’re not dependent on one product line to solve a problem. If your Gelco cap is sound but the liner below it isn’t, we can handle both in one visit and one written estimate.

We service Gelco caps and the chimneys they sit on using quality parts that fit the equipment. We don’t sell Gelco products or claim factory training.

Yes. We use parts that fit Gelco caps and perform the same job: shed water, screen sparks, and hold up to wind. We don’t claim to stock OEM or genuine Gelco parts, and we’re upfront about that. When a cap needs a new screen or a replacement, we choose a component that matches the flue’s dimensions and draft needs. You’ll know what we’re installing and why before we install it.
Most Gelco cap inspections and cleanings take about an hour, and a cap replacement adds a bit more time on the roof. A full sweep plus inspection is typically a single visit. If we find glazing that needs creosote removal, or a liner issue that needs resurfacing or relining, that’s scoped as separate work with its own written estimate. We’ll tell you at the inspection what the timeline looks like. Call (855) 617-0455 for a free estimate.
Gelco is a chimney cap brand, and caps are what we service and install. That includes single-flue caps, multi-flue caps, and caps sized for smaller flues. We handle re-seating after wind damage, screen and mesh repair, and replacement when a cap is cracked, rusted, or the wrong size. We also service the flue, damper, and liner beneath the cap, since a cap alone doesn’t make a chimney safe.
Servicing a cap with quality parts that fit it shouldn’t void a manufacturer warranty, but warranty terms are set by the manufacturer, not by us. We’re an independent provider, so we can’t speak for Gelco’s warranty policy. What we can do is document exactly what we found, what we installed, and why, so you have a clear record. If you have warranty questions, check with the manufacturer directly.
Typical Gelco cap inspection and cleaning in Lubbock runs in the range most homeowners expect for a standard sweep plus cap check, and cap replacement is priced separately based on flue size and access. The written estimate sets the final price, and the estimate itself is free. Nothing gets recommended without camera evidence you can see. Call (855) 617-0455 for an exact quote.
