Level 1 sweep and inspection to the NFPA 211 annual standard - flue, crown, cap, and flashing checked and photographed
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 Repair in Alpharetta: What to Know First
We provide independent Gelco chimney repair in Alpharetta with written prices before any work starts, typically scheduling within three to five business days during peak season. Most Gelco repairs run $450 to $2,800 depending on whether we’re repointing mortar joints, rebuilding a spalled crown, or replacing failed flashing on a multi-flue stack. The camera doesn’t soften anything, and neither do I - you’ll see the footage, get the written scope, and know the exact price before we touch a tool.
This page is for Alpharetta homeowners who already know they have Gelco components on their chimney and want a technician who understands how those specific parts age in north Georgia’s freeze-thaw cycle. Call (678) 679-0171 for a free estimate.
How Gelco Products Fail - and How We Fix Them
- Gelco Multi-Flue Chimney Caps (Model M-8, M-12 series): The 304 stainless mesh on these caps traps pollen and pine debris from Alpharetta’s heavy loblolly stands, accelerating corrosion at the corner welds where water pools after our sudden March temperature swings. We remove the cap, document the weld cracks with the camera, and either source a direct Gelco replacement through our Haven buying network or fabricate a heavier-gauge custom cap if the flue spacing is non-standard.
- Gelco Single-Flue Caps with Hip-Lid Design: The lid hinge pin seizes after five to seven years of pollen buildup mixed with condensation, which means the lid won’t lift properly during a chimney fire event. We disassemble the hinge, show you the galling on the pin, and replace with either an OEM Gelco pin or a marine-grade stainless equivalent that won’t bind - your call, priced both ways in writing.
- Gelco Top-Mount Dampers (Pre-2018 units): The cast-aluminum throat plate warps if the fireplace was ever operated with the damper partially closed, a mistake we see constantly in Alpharetta’s 1990s-era brick ranches off Webb Bridge Road. Warping creates a permanent gap that bleeds heat and lets rain in. We measure the throat opening, quote a Gelco replacement damper or a Lock-Top equivalent, and show you the smoke test before we leave.
- Gelco Chase Covers on Prefab Fireplaces: The factory bead around the collar pipe separates when the galvanized steel fatigues, usually around year twelve in our climate. Water runs straight down the pipe and pools in the firebox. We fabricate a replacement chase cover in .032 aluminum or copper, cut the collar to your exact pipe diameter, and seal with high-temp silicone - not the roofing caulk some crews use that turns to gum in six months.
- Gelco Spark Arrestor Screens: The 5/8-inch mesh required by some Alpharetta HOA covenants clogs with cottonwood fluff in May and June, creating a draft restriction that shows up as smoking into the room. We clean the screen, check the underlying cap for salt corrosion from our occasional ice events, and replace with a Gelco arrestor or a Copperfield equivalent that meets your HOA spec - documented with photos for your records.

Why Alpharetta Homeowners Call Emberly Chimney Cleaners Alpharetta for Gelco Work

We’ve worked chimneys across Alpharetta long enough to know which builders spec’d Gelco caps on their 2005-2015 builds and where the freeze-thaw damage tends to concentrate on north-facing exposures. Corrine Halstead and our crew don’t guess at parts fitment - we source Gelco, DuraFlex, HeatShield, and Olympia Chimney materials through the Haven buying network, which means we can offer both OEM and quality aftermarket without inflating either price.
The 365-Day Done Right Promise applies to every Gelco repair we touch. Background-checked, uniformed technicians. License number on the page. Written price before work starts, every time, no exceptions. That’s Haven Standard Clause 1, and it’s how we’ve operated since 2009.
FAQs
No - Gelco’s limited lifetime warranty on stainless caps covers manufacturing defects, not installation or subsequent damage, so independent repair doesn’t affect it. As an independent Gelco service provider, we document the cap’s condition before we start so you have a dated record if a defect claim ever arises. Call (678) 679-0171 for a free estimate.
Yes - we stock common Gelco damper components and can source discontinued throat assemblies through our Haven buying network, usually within five business days. When a part is truly obsolete, we quote a direct-fit replacement from Lock-Top or another quality line, with both options priced in writing. Call (678) 679-0171 for a free estimate.
The camera decides - not us, and not a guess from the ground. We run the Level 2 inspection, show you the flue footage, and explain whether the issue is surface spalling (repairable) or structural compromise requiring rebuild. Nothing is recommended without photo evidence you can see yourself. Call (678) 679-0171 for a free estimate.
Most Gelco cap, damper, or repointing jobs finish in one working day; crown rebuilds or partial rebuilds may need two days for proper cure time. We don’t rush mortar or sealant work - Haven Standard Clause 3 requires workmanlike completion, and that means letting materials set to spec. Call (678) 679-0171 to schedule.
Yes - we regularly repair and replace DuraFlex liners, HeatShield cerfractory coatings, Olympia Chimney components, and Famco hardware. Multi-brand fluency matters because most Alpharetta chimneys have mixed systems, and we won’t force a Gelco part where another manufacturer’s component is the better fit. Call (678) 679-0171 for a free estimate.
