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.

AfterWhy Seaford Homeowners Choose Gelco Chimney Cleaning
We provide independent Gelco chimney cap cleaning, repair, and replacement service throughout Gelco service in Seaford, NY, with same-day diagnosis and Level-2 camera inspection included on every call. Our technicians carry Gelco stainless and copper caps on the truck, so most Seaford homes get a proper fit without waiting on shipping. Call (516) 614-4632 to book.
Seaford’s position on the South Bay waterfront means every chimney cap faces a tougher life than its inland cousins. The salt-laden marine air rolling off Seaford Harbor corrodes metal faster, and the freeze-thaw cycles of Long Island winters force moisture into every seam and solder joint. Gelco caps hold up well against this, but “well” is relative when you’re 60 feet from the tide. We’ve worked on Gelco installations from Seamans Neck Road to the harbor’s edge, and we’ve learned which models survive Seaford’s conditions and which need more frequent attention.
We’re an independent Gelco service provider, not an authorized dealer. That distinction matters. It means we work for you, not for a manufacturer’s sales quota. If your Gelco cap can be repaired, we repair it. If it needs replacement, we size it correctly for your actual flue, not for a catalog number that might not match your 1958 chimney.
A clean chimney is not exciting. That is exactly the point.
Why Trust Hearthstone Chimney Co. for Your Gelco Chimney Cleaning?
Russell Haines learned the building trades through the construction program at Los Angeles Trade-Technical College before coming east and putting down roots in the chimney business on Long Island. For years now, he and our crew have worked chimneys throughout Seaford, including homes backing up to Seaford Harbor. He’s seen every way a flue can fail and a few homeowner repair attempts he’d rather not discuss. That experience shows up in how we handle Gelco products.
We know Gelco’s stainless steel single-flue caps, copper multi-flue caps, and custom configurations down to their mounting hardware and screen weld patterns. When a Seaford homeowner calls with a rattling cap or green stains on the brick, we don’t guess. We inspect, photograph, and give you a plain-English verdict you can see for yourself.
Our our Chimney Cleaning & Sweep services include Level-2 camera inspections that end with photos and a written report. Our 90-Day Done Right Promise covers every job in writing with no arguing. If it’s not right, we come back. That’s the Keystone Standard, and it’s been our way for over 42 years.
We stock genuine Gelco parts and equivalent-gauge aftermarket options from other US makers. We use what fits your chimney and your budget, and we explain the difference before we start. No surprises on the bill. The number on the estimate is the number on the invoice.
Common Gelco Chimney Cleaning Problems We Fix in Seaford
- Screen mesh separation on Gelco stainless caps. Gelco’s spot-welded screen mesh separates from the cap frame after years of coastal salt air and wind exposure. In Seaford, this happens faster than the manufacturer expects. Once the mesh pulls loose, sparks and embers can escape, and squirrels or raccoons gain access to the flue. We find this most often on caps facing the open water toward Seaford Harbor, where the salt load is highest.
- Cracked or stripped mounting legs. Gelco caps mount through legs that bolt into the chimney crown. When that crown is spalling or uneven, which is common on Seaford’s 1950s-60s brick chimneys, the legs crack or their bolt holes strip. The cap leans. It rattles in every nor’easter. We see this constantly on post-Sandy rebuilds where crowns were patched quickly rather than rebuilt properly.
- Pinhole corrosion on copper Gelco caps. Gelco’s copper line develops pinhole corrosion near the solder joints in Seaford’s salt-heavy air. The result is green staining down the chimney face and eventual water intrusion. Copper is supposed to weather, but Seaford’s marine environment accelerates the process beyond normal patination. We catch this early during camera inspection.
- Sizing mismatches on older Seaford chimneys. Gelco caps ordered for nominal flue sizes often don’t fit older Seaford chimneys with out-of-round or oversize clay flue tiles. A cap that sits too small leaves gaps. A cap that sits too large can’t mount securely. We measure the actual flue opening, not the original construction specs, which on a 65-year-old chimney are rarely accurate anymore.
- Storm damage from South Shore weather. Seaford’s exposure to nor’easters and hurricane remnants means Gelco caps take direct wind hits that inland caps never see. We’ve replaced caps after Sandy’s successors that were torn partially loose, bent, or had their spark arrestor screens collapsed inward by wind pressure. The 2012 storm surge itself left salt deposits in flues that continued corroding metal years later.
A Seaford homeowner called us because their Gelco stainless multi-flue cap was rattling in every nor’easter and they’d seen rust flakes on the roof. Our tech found two of the four mounting legs had cracked where they bolted into a spalling crown, and the screen mesh had pulled loose along one edge. We replaced it with a correctly sized Gelco stainless multi-flue cap, repointed the crown bolt holes, and screened the flues. No more rattle. The cap sits level.
Gelco Parts & Our Repair-vs-Replace Approach
We stock genuine Gelco stainless and copper caps as well as equivalent-gauge aftermarket caps from other US makers. Our Seaford warehouse carries common Gelco sizes for single-flue and multi-flue configurations, so most replacements happen in one visit without waiting on freight.
If a Gelco cap has only a failed screen or leg, we repair it. We weld mesh, fabricate legs, or repoint mounting points. If the frame itself is corroded, if the cap is undersized for your flue, or if the crown beneath it needs rebuilding, we recommend full replacement with a correctly sized unit. We show you the camera photos and explain which path costs less over time. Sometimes repair is the square deal. Sometimes replacement is. We don’t profit from selling you what you don’t need.
Call (516) 614-4632 and we’ll give you an honest assessment.
Our Gelco Service Process - Step by Step
- 1
Diagnosis with camera inspection. We arrive with a Level-2 camera system and inspect the flue, crown, and existing Gelco cap from top to bottom. You see the photos. We explain what we found and why it matters for your specific model.
- 2
Repair or replacement with proper parts. We use genuine Gelco components or matched-aftermarket equivalents sized to your actual flue dimensions. For Seaford’s older chimneys, we often need to measure on site rather than rely on original specs.
- 3
Testing and verification. We verify draft, check cap alignment, and confirm screen integrity. On multi-flue caps, we make sure each flue is properly vented and that the cap doesn’t create downdraft problems in Seaford’s prevailing winds.
- 4
Warranty documentation. Every job gets written documentation of work performed, parts used, and our 90-Day Done Right Promise. If something’s not right, we come back. No paperwork to dig up, no argument.
Gelco Products We Service & Install in Seaford
We work with the full Gelco residential line: stainless steel single-flue caps, copper multi-flue caps, custom chimney caps for non-standard flue configurations, and universal spark arrestor screens, offering Gelco service in Wantagh as well. Our Seaford-area trucks carry the most common Gelco stainless and copper sizes, plus mounting hardware and screen mesh for field repairs.
For chimneys converted from oil to gas, we frequently install Gelco multi-flue caps that cover multiple flues with a single properly sized unit. This is common in Seaford’s split-levels and Cape Cods where the original construction left two or three separate flue tiles clustered together.
We Also Service These Brands
We’re not a single-brand shop. Our technicians are equally familiar with DuraFlex liner systems, HeatShield cerfractory flue resurfacing, Olympia Chimney components, Famco venting products, and Copperfield chimney supplies. If your Seaford chimney needs more than a cap, we handle it without calling in subcontractors.
FAQs - Gelco Chimney Cleaning Service in Seaford
No. We are an independent Gelco service provider, not an authorized dealer or factory representative. We work for homeowners, not manufacturers. This means we repair when possible instead of pushing replacement, and we source parts from multiple suppliers to get the right fit at a fair price.
Yes, when they’re the right choice. We stock genuine Gelco stainless and copper caps, and we also carry equivalent-gauge aftermarket options from other US makers. We explain the difference and let you decide. Both paths are covered by our 90-Day Done Right Promise.
Most Gelco cap repairs or replacements in Seaford take two to four hours from arrival to completion. We carry common sizes on our trucks, so most jobs finish in a single visit. Complex crown repairs or custom sizing may require a return trip.
We service and install Gelco stainless steel single-flue caps, copper multi-flue caps, custom chimney caps, and universal spark arrestor screens. If you’re unsure which model you have, we identify it during inspection and match replacement parts accordingly.
Gelco’s warranty covers manufacturing defects, not installation or field modifications. As an independent provider, our work doesn’t extend or void the manufacturer’s original warranty on the product itself. We document everything we do in case you need to file a claim with Gelco directly.
Gelco cap inspection and cleaning typically runs $150-$250 when done as part of a full chimney sweep. Cap replacement with a new Gelco unit ranges from $400-$900 depending on size, material (stainless vs. copper), and whether crown repair is needed. We give upfront pricing before starting, and estimates are free. Call (516) 614-4632 for an exact quote on your specific chimney.
Yes. We match the cap to your flue and your budget, not to a brand loyalty program. If another manufacturer’s cap fits better or costs less for equivalent quality, we’ll tell you. Most Seaford homeowners choose Gelco again because the fit is proven, but the decision is yours, and we also provide Massapequa Gelco service.
Gaps larger than half an inch between the cap’s screen wall and the flue tile edge mean the cap is undersized. You might also notice debris collecting on the smoke shelf, animal activity, or water staining on the firebox walls. We measure with a ruler during camera inspection and show you the photo.
Yes. Gelco’s multi-flue cap line covers two, three, or more flues under a single hood. We install these frequently in Seaford’s 1950s-60s homes where the original construction clustered flue tiles together. Proper sizing is critical; we measure the full footprint including the space between flues.
Seaford’s salt air accelerates galvanic corrosion at the solder joints, where dissimilar metals meet. Normal copper patina is uniform and protective. Green staining concentrated at joints indicates active corrosion that will eventually pinhole. We catch this during inspection and can re-solder or replace before water intrusion starts.
Yes, and we often do both in the same visit. A cap mounted to a deteriorated crown will fail again quickly. We repoint or rebuild the crown, let it cure if needed, then install the cap to a sound surface. The photo report shows you the crown condition before we start.
