Chimney sweep logs do not sweep chimneys. They loosen some creosote - which then falls where a brush and vacuum still have to collect it.
Gelco Chimney Cleaning in Lawrenceville, GA | Flint Chimney Co Alpharetta
We provide independent Lawrenceville Chimney Sweep and Gelco service across the area, and the one thing that sets our work here apart is that we don’t just sweep – we document what Lawrenceville’s humidity, clay soil, and older housing stock actually do to Gelco liners and caps. Our techs service Gelco snap-lock and flex liners, multi-flue caps, and custom caps in homes from Sugarloaf Parkway to the downtown square. If your Gelco liner is drafting poorly or your cap is pulling away from the crown, call (762) 600-1468 and we’ll put a written price in your hand before any work starts.
Why Lawrenceville Residents Choose Us for Gelco Service
Hank Delano, our owner, learned the trade at Los Angeles Trade-Technical College and has spent more than two decades on roofs and in fireboxes. He’ll tell you that a Gelco liner holds up fine when it’s installed square and maintained, but Lawrenceville’s wet springs and summer thunderstorms punish any seal or seam that’s even slightly off. That’s why our techs inspect the mounting brackets, the tee connection, and the crown-to-cap joint on every Gelco system we clean. We’re not a manufacturer-authorized shop – we’re an independent Gelco sales & service provider, which means we call it as we see it. If the original parts can be cleaned and re-sealed, we clean and re-seal them. If they’re beyond saving, we say so plainly and hand you options with prices attached.
Our background-checked, uniformed techs arrive inside the window we give you. Every repair carries the 365-Day Done Right Promise: a written guarantee valid one full year from the service date. If a covered repair fails, we come back at no charge. No argument, no re-quote, no fine print.

Common Gelco Chimney Cleaning Problems We Solve in Lawrenceville
- Kinked flex liners at the smoke shelf. In older Lawrenceville bungalows with tight flue offsets, a Gelco flex liner can deflect as it passes the smoke shelf. That kink traps creosote and disrupts draft. We see this constantly in pre-1940 homes near the square, and the fix starts with a camera inspection to confirm the bend before any cleaning method is chosen.
- Rusted multi-flue cap brackets and seam separation. Lawrenceville’s summer thunderstorms hammer exposed cap metal. Gelco multi-flue caps tend to show rust at the mounting brackets and along seams first. We remove the cap, inspect the crown underneath, and re-mount with corrosion-resistant stainless hardware where the deck allows it.
- Creosote creep at the tee connection on snap-lock liners. In 1980s and 1990s Lawrenceville suburban homes, we regularly find thickened glaze in the last foot before the tee. A rotary whip can overshoot that area on a stiff liner, so we switch to sectional cleaning with hand brushes to clear the connection properly.
- Failed caulk seal between custom cap and crown. On downtown square homes with exposed brick chimneys, Gelco custom caps often pull away from the crown as the caulk ages and water gets behind the cap. The cap itself may be fine; the seal usually isn’t.
- Spalling brick below the crown. Older Lawrenceville chimneys without a proper overhanging crown wick water into the brick below. When we’re called for a Gelco cap replacement, we check the crown condition too, because a good cap on a failed crown still leaks.
Gelco Service in Lawrenceville: What Local Conditions Mean for Your Equipment
Lawrenceville is the only city in Gwinnett County with a downtown square where the original 1823 courthouse chimney still stands. The pre-1940 homes radiating out from that square share a common problem: their chimneys often lack proper crowns, so water runs straight down the flue and behind the cap. When we do Gelco cap and crown work around the square, we’re not just sealing the top – we’re matching the historic brick profile so the repair doesn’t look like a patch. A generic cap with a modern profile on a 1920s bungalow chimney near the square sticks out. Our techs carry low-profile Gelco custom caps and a range of aftermarket top plates sized to the original flue openings, which means the finished job sits right on the brick and keeps water out without changing the chimney’s lines.
Our tech pulled a Gelco flex liner from a 1992 rancher off Sugarloaf Parkway and found a kink at the smoke shelf that was trapping creosote and causing a smoky backdraft. We straightened the liner, smoothed the creosote with a rotary whip, and installed a new Gelco multi-flue cap with a corrosion-resistant stainless band. The homeowner’s next burn produced a clean draft and no smoke roll-out. That’s the kind of failure we look for on every Lawrenceville Gelco system, because wet winters and occasional fireplace use mean creosote gets a foothold in exactly those tight spots.
Gelco Models & Products We Service in Lawrenceville
We service all four main Gelco product families: snap-lock round chimney liners, flex chimney liners, multi-flue chimney caps, and custom chimney caps. For liner couplings, top plates, and cap mounting hardware, we stock aftermarket components that match or exceed Gelco specs – this keeps turnaround fast for Lawrenceville service area calls without waiting on factory orders. We only recommend full Gelco liner replacement when the existing liner is cracked or separated beyond repair. Otherwise we clean, re-seal, and re-mount the original parts. When a genuine Gelco cap must be replaced, we install the correct Gelco model for the flue arrangement and match the mounting footprint to the existing crown.

AfterGelco Service Pricing in Lawrenceville
A standard Gelco chimney cleaning in Lawrenceville typically runs $180 – $260, which includes the sweep, our Chimney Inspection in Lawrenceville, and a written condition report with photos. Cap and crown work adds cost depending on the cap size and crown condition: plan for $450 – $700 for a replacement Gelco multi-flue cap with new stainless mounting hardware, and $600 – $950 when the crown needs coating or a rebuild of the top layer. What drives the price here is access – steep roofs, tall flues, and tight downtown clearance all add labor. Every quote is written before work starts, so the number you approve is the number on the invoice. Call (762) 600-1468 for an exact quote; estimates are free.

FAQs – Gelco Chimney Cleaning in Lawrenceville
The kink is almost always at the smoke shelf, where the liner has to make a sharp transition inside the existing flue. In 1980s Lawrenceville builds, the flue tile offset is often tighter than modern specs allow, so a flex liner deflects under its own weight. We confirm the kink with a camera, then decide whether adjusting and re-securing the liner is enough or whether a new liner section is required. Call (762) 600-1468 and we’ll get a tech out to look.
Yes. We can match the existing cap’s footprint and profile with either a genuine Gelco multi-flue cap or an aftermarket equivalent that meets the same spec. We’ll remove the rusted cap, inspect the crown ledge it sat on, and install the new cap with stainless hardware. We’ll also check whether water was getting under the cap and into the flue – which is common here. A quick call to (762) 600-1468 gets you on the schedule.
It can be, because Lawrenceville’s humid air keeps creosote sticky instead of flaking off. A liner used only a handful of times each winter can develop a thick glaze at the tee connection and smoke shelf. For Gelco snap-lock liners, we often use sectional cleaning rather than a rotary whip to clear those sections thoroughly. The sweep is part of the standard rate; call (762) 600-1468 for a written price.
Not necessarily. We coat and rebuild crowns in layers using a masonry bonding agent and a proper overhang, and we re-seat the Gelco cap with fresh mechanical anchors. A full rebuild is only needed when the brick below the crown is loose or the flue tile has shifted. We’ll show you the camera footage and tell you plainly what has to happen. For a fast written estimate, call (762) 600-1468.
Yes. We clean HeatShield-resurfaced liners with lower-torque rotary whips or hand brushes to avoid abrading the surface. The camera inspection beforehand tells us which method is safe for your liner’s condition. We work with HeatShield, DuraFlex, Gelco, and other trade brands, so this situation is straightforward for us. Call (762) 600-1468 to book a clean-and-check.
