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 Camden: What to Know First
We provide independent Gelco chimney cap and crown service in Camden, typically scheduling within a week and completing most jobs in a single visit. Every Gelco repair starts with a camera-scan inspection and ends with a written price you saw before we touched a tool, backed by our 365-Day Done Right Promise. This page is for Camden homeowners who already own a Gelco cap or crown and need honest answers about what’s failing, what it costs, and whether the fix can wait. Call us at (856) 741-9572 for a free estimate, or read on for the specifics.
How Gelco Products Fail - and How We Fix Them
- Gelco Ultra-Seal series - mesh corrosion at the Jersey shore. The 304 stainless mesh on Ultra-Seal caps holds up well inland, but in Camden’s river-humid summers and salt-air drift from the Delaware, we’ve seen weld-point rust appear in 6-8 years instead of the 15+ you’d expect. We replace with 316L marine-grade mesh or source a factory-spec Gelco replacement when the frame is still sound. Corrine Halstead’s crew logs the mesh grade on every report so you know what you’re getting.
- Gelco Multi-Flue caps - lid sag on wide-set flues. The Multi-Flue line uses a single lid spanning two or three flue tiles. In Camden’s older row homes near Cooper Street, where flue spacing was never standardized, the cross-brace can fatigue and the lid tilts toward the low side. Water pools. We measure the flue spread with a story pole, then either shim the existing brace or fabricate a custom cross-member that carries the load squarely.
- Gelco standard galvanized caps - crown washout underneath. The budget galvanized line is often installed without a proper crown slope beneath it. Rain runs under the cap lip, dissolves the mortar wash, and the crown cracks from freeze-thaw. We don’t just swap the cap. We cut back to sound concrete, repitch the crown with proper drainage, then seat a new cap on a bed of sealant that won’t squeeze out in Camden’s January cold snap.
- Gelco top-mount dampers - cap interference after seasoning. The Gelco Lyemance-style top-sealing damper works well until the chimney cap above it collects creosote or the damper plate warps slightly from over-firing. Then the cap skirt catches the plate on opening. We see this in Fairview and Cramer Hill where homeowners burn pressed logs heavily. The fix is either cap skirt trimming or a damper adjustment, but we camera-check the flue first because the real problem is often Class III glazed creosote adding weight to the cap.
- Gelco crown sealant - UV chalking on south-facing stacks. Gelco’s brush-on crown coating is decent acrylic, but on south and west exposures in Camden’s summer sun, we’ve tracked chalking and micro-cracking at year 4 instead of year 8. We strip to bare concrete, apply a silane-siloxane penetrating sealer first, then topcoat with a modified acrylic that flexes through freeze cycles. The camera shows it. The report names it. The price is written before we ask for anything.
Our Gelco Chimney Cap & Crown Process

- 1
Call and schedule. A live person answers. We book a window, text you when the tech is en route, and send background-checked, uniformed crew - license number on the page, named tech assigned.
- 2
Camera-scan inspection (NFPA 211 Level 2). We run the camera down the flue, photograph the crown from the roof, and measure cap dimensions. You see the footage. We don’t guess at what’s wrong.
- 3
Parts decision: OEM Gelco or quality aftermarket. If your cap is under warranty and the failure is a known defect, we source factory Gelco through Haven’s buying network. If the line is discontinued or the OEM part is back-ordered (we’ve waited 3 weeks for certain Multi-Flue lids), we fabricate equivalent from Copperfield or Famco stock and document the substitution on your record.
- 4
Repair with written scope. Crown rebuilds get formed and poured to NFPA 211 slope specs, minimum 2-inch overhang, drip edge turned. Cap installs get torque-checked fasteners and high-temp sealant rated to 400°F continuous. You get the written price before we start - Haven Standard Clause 1.
- 5
Post-work test and photo record. We run a combustion spillage test if the flue was disturbed, photograph the finished crown and cap from two angles, and upload to your documented record - Haven Standard Clause 4, continuous since 2009.
- 6
Cleanup and 365-Day Done Right Promise. We haul old material. If the cap leaks or the crown cracks through our work in year one, we make it right. No argument.

Why Camden Homeowners Call Level Two Chimney Camden for Gelco Work

We’ve inspected and cleaned more than 38,000 chimneys since 2009, and a healthy share of those were Gelco caps in Camden County row homes, twins, and post-war ranches. Our techs know the difference between a Series 8 and a Multi-Flue at roofline glance. When Gelco parts are scarce, we don’t leave you hanging - our Haven buying network stocks DuraFlex, HeatShield, Olympia Chimney, Famco, and Copperfield equivalents, and we document every substitution so your record stays clean. The 365-Day Done Right Promise is stamped on every job. Calls are answered live, 24/7, by a person who can book you. No voicemail. No web-form black hole.
FAQs
No, if the repair uses OEM-equivalent parts and proper installation methods. As an independent Gelco service provider, we source factory-spec components when available and document everything. If your cap has a remaining manufacturer warranty, we note the serial number and installation date on your record so any future claim stays valid. Call (856) 741-9572 and we’ll check your coverage.
Expect 10-15 years for 304 stainless models inland, 6-10 if you’re near the Delaware with salt-air exposure. The 316L marine-grade line adds roughly 5 years. We see the difference in real time - caps on Cooper Street row homes versus those in Waterfront South - and we note the grade on your report so you know what you have.
Yes. We fabricate custom equivalents from Copperfield and Famco stock when Gelco has retired a line. We measure your flue tile outside dimensions, check draft requirements, and build to match. The substitution is documented under Haven Standard Clause 4, and the price is written before fabrication starts.
Crown coating works when the concrete is sound - no exposed rebar, no through-cracks, less than 1/4-inch surface spalling. We camera the flue interior for water tracks and hammer-test the crown. If water has reached the rebar mesh, the rust expansion will blow the crown apart in 2-3 winters. We show you the footage, quote both options when borderline, and never push rebuild without evidence you can see.
Typically within a week, sooner if the crown is actively leaking into the flue. We don’t do same-day dispatch - a proper inspection takes time - but we do answer live 24/7 and hold seasonal priority slots for active water intrusion. Call (856) 741-9572 for the next available opening.
