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.

AfterGelco Chimney Cap & Crown in Sandy Springs: What to Know First
We provide independent Gelco chimney cap and crown service in Sandy Springs, with most cap replacements and crown repairs completed in a single visit once parts are confirmed. A written price, written scope, and written warranty are delivered before any work begins - no exceptions. If you own a Gelco multi-flue cap, a Gelco stainless single-flue, or you’re seeing water stains on the firebox ceiling, this page covers what fails, what it costs, and how we document it. Call (470) 480-0885 for a free estimate or to schedule a camera inspection.
How Gelco Products Fail - and How We Fix Them
- Gelco Multi-Flue Series (Model M-xxx): Hood separation at the weld seams. The multi-flue hoods use a rolled-edge seam where the top panel meets the skirt. In Sandy Springs, the thermal cycling between 95°F summer attic heat and winter firebox temperatures fatigues this joint after 8-12 years. We see the hood lift or separate entirely, exposing the flue terminals to direct rainfall. Our fix: remove the failed hood, assess the mesh condition, and install a replacement Gelco hood or a compatible aftermarket unit with fully welded seams. We photograph the seam failure before quoting so you see why replacement beats re-welding.
- Gelco Single-Flue Caps (SC series): Mesh screen collapse from creosote weight. The SC line uses a finer 5/8-inch mesh that traps more debris - good for spark arresting, bad when homeowners skip sweeps. Heavy Class III creosote, the hard, tar-like buildup from smoldering fires, loads the mesh until it sags into the flue opening. Our fix: sweep the flue first, then replace the cap with either an OEM Gelco SC or a DuraFlex equivalent with a heavier-gauge mesh. We won’t install a new cap over a dirty flue; that’s a repeat failure in two seasons.
- Gelco Band-Around-Brick mounting: Corrosion of the galvanized tension band. Sandy Springs gets 50+ inches of annual rainfall, and the standard Gelco galvanized band rusts through at the adjustment slot within 6-10 years on north-facing exposures. The cap loosens, tilts, and eventually detaches in wind. Our fix: replace with a 304 stainless band or upgrade to a Gelco screw-mount cap if the flue tile allows. We note the exposure and band material on every quote.
- Gelco crown-mounted caps (CC series): Crown deterioration hidden beneath the cap flange. The CC line bolts through the crown concrete, which is fine until the crown itself cracks or spalls - concrete flaking away in layers - underneath the flange. Homeowners see a cap that looks intact while water migrates through the crown and down the flue liner. Our fix: lift the cap, assess the crown with a hammer test and photo documentation, then either reseat on a repaired crown or recommend crown coating with HeatShield if the damage is surface-level. We show you the spalling before we recommend anything.
- Gelco wind band accessories: Missing or improperly tensioned secondary straps. The optional wind band kit is supposed to anchor the cap to the chimney body below the crown, but we find roughly half the installed bands in Sandy Springs are either overtightened (crushing the mesh) or left loose enough to chafe in a storm. Our fix: remove and inspect, replace with stainless hardware, and torque to Gelco’s spec. If the original band is absent, we quote it as part of the cap replacement - a $45-$75 add-on that prevents a $200+ cap loss in the next derecho.
Our Gelco Chimney Cap & Crown Process
- 1
Call and schedule. A live person answers, notes your Gelco model if you know it, and books a camera inspection. You’ll get a text when your tech is en route.
- 2
NFPA 211 Level 2 inspection. Corrine Halstead’s crews camera-scan the flue, inspect the crown and cap from the roof, and document everything. The camera doesn’t guess. Neither do we.
- 3
Parts decision. We check Gelco OEM availability against our Haven buying network (DuraFlex, Olympia Chimney, Famco equivalents). If OEM lead time exceeds five business days and an aftermarket part meets or exceeds Gelco spec, we present both options with warranty terms.
- 4
Written quote delivered. Scope, price, warranty, and timeline - in writing, before any tool comes out. Clause 1 of the Haven Standard.
- 5
Repair and test. Cap or crown work is completed, the flue is smoke-tested for draft integrity, and all fasteners are torqued to spec.
- 6
Photo record and cleanup. Before-and-after images, a documented completion record, and your copy of the warranty. Clause 4 of the Haven Standard, same as every job since 2009.

FAQs
Gelco’s original warranty on materials typically expires after the stated term regardless of who services the cap; installing a non-Gelco replacement does not void coverage on other Gelco components that remain under warranty. As an independent Gelco service provider, we source OEM when available and document part numbers for your records. If warranty status matters for a specific component, we’ll check it before ordering. Call (470) 480-0885 for a free estimate.
Most Gelco cap replacements are completed in 45-90 minutes once our tech is on site, assuming no hidden crown or flue damage. Crown repairs add 2-4 hours. We book enough time to do it once and do it right - rushed cap installs are why we find loose bands and tilted hoods on other people’s work. Call (470) 480-0885 to schedule.
Surface cracking without structural spalling can often be addressed with crown coating (HeatShield or equivalent), which we apply after wire-brushing and priming. Deep cracks, crumbling edges, or exposure of the reinforcing mesh mean the crown needs partial or full rebuild - we show you the camera and hammer-test footage before recommending either path. Call (470) 480-0885 for an inspection and written quote.
We stock common Gelco SC and M-series caps and maintain relationships with regional distributors for next-day availability on less common sizes. If Gelco lead time exceeds five business days, we present a quality aftermarket equivalent from our Haven buying network with equivalent or better specs and warranty. You choose before we order. Call (470) 480-0885 to confirm availability for your model.
Water in the firebox, rust stains on the damper, or white efflorescence on the firebox walls are symptoms of either cap or crown failure - or both. The only way to know is to lift or remove the cap and inspect the crown surface and flue liner top. We do this as part of our standard camera inspection, photograph what we find, and explain it before quoting. No guessing, no scare tactics. Call (470) 480-0885 to book.
