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 Cap & Crown in Roanoke: What to Know First
We provide independent Gelco chimney cap and crown service in Roanoke, with most Gelco cap replacements and crown repairs completed in a single visit. Our no-hassle upfront pricing means the estimate we give is the number on the invoice. Gelco caps and crowns hold up well against Virginia weather, but after fifteen to twenty years in the Roanoke Valley, even the best stainless steel can fatigue and concrete crowns can spall from freeze-thaw cycles. This page is for homeowners who already have a Gelco product on their stack and need to know whether it can be repaired, what a proper fix costs, and who in Roanoke actually stocks the right parts. Call (540) 787-3302 for a free estimate. A clean chimney doesn’t announce itself. Neither does a problem - until it does.
How Gelco Products Fail - and How We Fix Them
- Gelco Ultra-Tops with mesh fatigue in South Roanoke. The 3/4-inch stainless mesh on older Ultra-Tops eventually work-hardens from thermal cycling, especially on homes near Mill Mountain where wind-driven rain accelerates corrosion at the weld points. We replace with OEM-spec Gelco mesh or upgrade to a heavier-gauge aftermarket screen if the homeowner burns pine regularly.
- Gelco Multi-Flue caps with sagging lids in Grandin Court. The cross-braced lid design on Gelco’s multi-flue line can develop a slight bow when flue gases exceed 600 degrees repeatedly, which happens more than you’d think with older Buck stoves. We measure the deflection, straighten or replace the lid, and check draft before we leave.
- Gelco standard caps with base ring separation in Wasena. The rolled base ring on pre-2010 Gelco caps was spot-welded at four points; after a decade of Roanoke’s wet winters, those welds can pop. We either re-weld with 308L filler or replace the entire base if the anchor tabs have torn.
- Gelco crown-forming caps with trapped moisture in Raleigh Court. Gelco’s integrated crown-forming caps are clever, but if the original installer didn’t slope the crown properly, water pools under the cap’s drip edge. We remove the cap, re-pitch the crown with proper slope toward the edge, and reinstall with a bead of high-temp silicone that won’t harden and crack.
- Gelco copper-finish caps with galvanic corrosion in Cave Spring. The copper-bonded finish on decorative Gelco caps looks sharp, but if a homeowner or a previous contractor used galvanized fasteners, the dissimilar metals set up a battery effect that eats the fastener and stains the masonry. We switch to 304 stainless hardware and treat any staining with a mild acid wash that won’t harm the brick.
Our Gelco Chimney Cap & Crown Process
- 1
Call and schedule. A live person answers, 24 hours a day. We ask for the Gelco model if you know it, but most folks don’t, and that’s fine.
- 2
Level-2 camera inspection. Our tech arrives in uniform, runs a camera up the flue, and photographs the cap, crown, and top course of brick. You see the photos on a tablet before we quote anything.
- 3
Parts decision. If your Gelco cap is a current model, we quote OEM. If it’s discontinued, we source quality aftermarket from our regular suppliers or fabricate a match. We explain the trade-off and let you decide.
- 4
The repair. Crown repairs get a bonding agent, new mortar mix with proper Portland-to-sand ratio, and a brush-applied crown sealant rated for 10-year UV exposure. Cap installs get stainless hardware, proper overhang, and mesh sized to your burning habits.
- 5
Test and document. We run the camera again to confirm no debris fell, check draft with a manometer, and email you the photos with a plain-English summary.
- 6
Cleanup and guarantee. We haul off the old material. Your 90-Day Done Right Promise goes in writing before we leave. If it’s not right, we come back. No arguing.

Why Roanoke Homeowners Call Hearthstone Chimney Co. for Gelco Work
We’ve been on roofs in Roanoke since 1984. Russell Haines and our crew have handled Gelco products long enough to know which part numbers changed in 2012, which caps fit older Superior prefab fireplaces common in the Valley, and when a $12 fastener fix beats a $400 cap swap. Our 90-Day Done Right Promise is in writing, no arguing. Photos you can see, a plain-English verdict. Done right - and we stand behind it. We also carry DuraFlex liner parts and HeatShield resurfacing materials, so if your Gelco cap job reveals a deeper problem, we handle it without a second trip. A square deal: no surprises on the bill. We’ll be there when we say.
FAQs
No, as long as OEM-spec parts are used and the work is documented. Gelco’s limited lifetime warranty covers manufacturing defects, not installation errors or weather damage. We keep photos and part numbers on file so any future warranty claim has backup. Call (540) 787-3302 if you need help with a claim.
Yes, for most lines. We maintain relationships with distributors who stock orphan inventory, and we can fabricate custom stainless caps in-house for the few models that are truly gone. If your cap is one of the rare exceptions, we’ll know within ten minutes of seeing it.
If the crown has hairline cracks but solid thickness everywhere, a professional coating usually adds 8 to 12 years. If it’s spalled down to the rebar mesh, or if water is entering the chase, a full rebuild is the only honest fix. We show you the camera footage and give both options when both are viable.
Most single-flue swaps take 45 minutes to an hour and a half. Multi-flue caps or jobs requiring crown work first can run half a day. We book enough time that we’re not rushing, and we don’t schedule another call on top of yours.
Water stains on the ceiling near the fireplace usually mean crown failure. Water running down the outside of the chimney or rust on the firebox usually means cap failure. But both can fail together, and only a camera inspection from the top down tells the full story. Call (540) 787-3302 for an exact quote - estimates are free.
