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 Cleaning in Staten Island, CA | Alcott Chimney Sweep
We clean and service Gelco chimney systems across Staten Island, from Tottenville up to St. George, and also provide Gelco repair in Brooklyn. One thing separates our Gelco work here from anywhere else: we know how this island’s salt air and post-Sandy rebuild history affects these liners specifically. If you own a home with a Gelco flue, call (336) 863-3889 and we’ll tell you exactly what needs attention before any work starts.
Alcott Chimney Sweep has worked on Gelco stainless liners, triple-wall pipe, and caps since long before the line was discontinued. We’re an independent service provider. We are not manufacturer-authorized, which means we’re free to give you a straight answer about whether your Gelco system can be saved or needs replacement. Ruben Castellano leads our team, and he’s spent nearly twenty years working chimneys across the LA basin before bringing that experience here. If your Gelco flue is showing signs of trouble, we’ll show you what we find and tell you what it actually means.

Why Staten Island Residents Choose Us for Gelco Service
Most chimney companies on Staten Island don’t know Gelco as anything more than a name on a cap. We do. Our techs have opened hundreds of Gelco systems over the years, and we know the weak points: the top three feet of liner where salt spray pits the 304L stainless, the flue collar where rushed Sandy rebuilds left gaps, the triple-wall insulation that soaks up attic moisture in older homes without vapor barriers.
Ruben Castellano grew up in Boyle Heights and learned heating and ventilation systems through the HVAC program at East Los Angeles College before apprenticing under a veteran sweep. That apprenticeship taught him the difference between a flue that looks clean and one that’s actually sound. He brings the same standard to every Gelco inspection on Staten Island.
Every technician we send is background-checked, identity-verified, uniformed, and announced to you by name and photo before the visit. You’ll know who’s coming before the truck pulls up. That’s the Threshold Standard, and it’s not optional. Every job also comes with a written price before work begins and a written guarantee on every repair. If the repair fails within the coverage period, the second visit is free.
Common Gelco Chimney Cleaning Problems We Solve in Staten Island
- Salt-air pitting on the top section of Gelco liners. Staten Island is fully encircled by tidal waterways: the Kill Van Kull, Arthur Kill, and Raritan Bay. Prevailing winds push salt spray inland year-round, and Gelco 304L stainless liners often show pitting at the top two to three feet. We see this on almost every coastal-adjacent home we inspect, especially in South Shore neighborhoods like Great Kills and Annadale.
- Post-Sandy liner misalignment at the flue collar. Hurricane Sandy hit Staten Island hard in October 2012, and hundreds of South Shore chimneys were patched rather than properly rebuilt. Gelco liners installed during those rushed rebuilds in Midland Beach, New Dorp Beach, and Oakwood Beach frequently show gaps, misalignment, and premature corrosion at the collar. A standard sweep that doesn’t look for these specific patterns will miss it.
- Insulation breakdown in Gelco triple-wall pipe. Older Staten Island homes, particularly ranches and Colonials built in the 1970s through 1990s, often lack proper attic vapor barriers. When Gelco triple-wall insulation absorbs moisture in those unheated attics, it rusts from the inside out and draft performance drops. We open these systems and check the insulation, not just the flue surface.
- Crown and flashing incompatibility after masonry rebuilds. Original Gelco caps and flashing often don’t mate correctly with post-Sandy masonry work, especially in Oakwood Beach and Midland Beach. Water gets in, sits at the flue collar, and accelerates corrosion. We replace caps and re-flash using coastal-rated stainless hardware.
- Zero-clearance Gelco fireplaces nearing end of rated lifespan. The South Shore was heavily built out with builder-grade homes in the 1970s – 1990s, and many have prefab zero-clearance fireplaces now 30 – 50 years old. If your Gelco unit is in that range, we’ll tell you plainly whether it’s safe to keep using or time to plan for replacement.
Gelco Service in Staten Island: What Local Conditions Mean for Your Equipment
Here’s what makes Staten Island different from every other Gelco service market in the country. The island is NYC’s only predominantly single-family borough, which means it has the highest concentration of wood-burning fireplaces and masonry chimneys per capita in the five boroughs. But it’s also completely surrounded by tidal water. Salt air and nor’easter winds hit these chimneys differently than anything in Queens or the Bronx. The result: Gelco stainless liners on Staten Island corrode faster than the same liner would with Gelco service in Manhattan or another inland NYC neighborhood. The top few feet of a Gelco 304L liner exposed to Kill Van Kull spray can pit within a decade, while an identical liner in, say, Forest Hills might go twenty years without visible damage.
Add Hurricane Sandy to that equation. The rushed rebuilds along Midland Beach, New Dorp Beach, and Oakwood Beach produced a wave of Gelco installations that were never properly sized or code-compliant. We routinely find liners that passed informal post-storm repairs but now show hidden corrosion at the flue collar, something a generic sweep would never catch. That’s why every Gelco cleaning we do on Staten Island includes a Chimney Inspection - Staten Island focused on corrosion as standard, not as an add-on. We check the cap, the top three feet of liner, the flue collar, and the flashing, because those are exactly the places this island’s conditions attack first.
Gelco Models & Products We Service in Staten Island
We work on the full Gelco product line: 304L stainless flexible liner kits, Triple-Wall insulated chimney pipe, Rain Cap and Multi-Flue Cap series, and Top-Plate and flashing kits. For replacement parts, we source OEM-spec stainless liners and caps from legacy stock when available. When legacy stock runs thin, we use UL-listed aftermarket equivalents that match Gelco’s dimensions and alloy to the millimeter. Nothing improvised, nothing box-store. If your existing Gelco pipe passes a Level 2 inspection, we’ll recommend relining over full replacement every time. But we will not patch a corroded Gelco liner that’s already failing. That’s a false economy, and we’d rather tell you the truth than sell you a temporary fix.
Gelco Service Pricing in Staten Island
A standard Gelco chimney cleaning and inspection on Staten Island typically runs $180 – $340, depending on chimney height, accessibility, and the amount of creosote buildup. If repairs are needed, you’ll get a written price before any work begins. That’s not negotiable. It’s how we’ve operated since 2002. What drives cost up: coastal corrosion repair, liner section replacement, cap replacement with coastal-rated hardware, and masonry re-flashing. What the free estimate includes: a thorough inspection, photos of what we find, and a plain-English explanation of what needs attention now versus what can wait. Call (336) 863-3889 and tell us what you’re seeing. We’ll tell you what it actually means and what it costs to fix.

FAQs – Gelco Chimney Cleaning in Staten Island
Yes. If your Gelco liner was installed during the post-Sandy rebuild period in South Shore neighborhoods like Midland Beach, New Dorp Beach, or Oakwood Beach, a Level 2 inspection is the only way to verify the liner was properly sized, secured, and code-compliant. Many of those installations were rushed and never inspected. We routinely find gaps at the flue collar, misaligned sections, and early-stage corrosion in these systems. A Level 2 inspection gives you a camera view of the full flue interior, so you can see exactly what’s there. Call (336) 863-3889 to schedule yours.
Staten Island’s salt air attacks the top two to three feet of Gelco stainless liners first, because prevailing winds carry salt spray inland year-round from the Kill Van Kull, Arthur Kill, and Raritan Bay. Over time, the 304L stainless develops pitting, especially near the cap and flashing. Left unchecked, pitting becomes through-wall corrosion, and the liner loses its structural integrity. We inspect the top section with a camera on every Gelco cleaning, and we’ll show you the photos. If we find early pitting, we can often replace just the damaged top section rather than the entire liner. Call (336) 863-3889 to book a coastal-corrosion inspection.
In many cases, yes, we can replace just the top damaged section. If a Level 2 inspection confirms the lower liner is sound, we cut out the corroded top portion and install a custom-fabricated stainless extension that matches Gelco’s dimensions and alloy. We did exactly this at a ranch in Great Kills where a 1990s Gelco liner had heavy pitting on the top three feet from salt exposure. The lower liner was fine, so a full reline would have been waste. We’ll tell you honestly when a section replacement is appropriate and when a full reline is the only safe option. Call (336) 863-3889 for a camera inspection and a straight answer.
First, don’t use the fireplace until the cap is inspected. A damaged cap lets water and wind-driven rain into the flue, and on Staten Island that water carries salt. Within a season you can have corrosion at the liner top. We stock Gelco Rain Caps and Multi-Flue Caps locally, along with coastal-rated stainless replacements when legacy Gelco stock is exhausted. We’ll also check the flashing and crown while we’re up there, because nor’easter damage rarely stops at the cap. Replacement is straightforward, and you’ll get a written price before we start. Call (336) 863-3889.
Yes. Waterproofing is one of the most effective things you can do for a Gelco chimney on Staten Island, especially if your crown is original to a 1970s – 1990s build. We apply vapor-permeable waterproofing agents to the masonry, which repels water while still letting the chimney breathe. The goal is to keep salt-laden moisture from soaking into the crown and flashing, which is what accelerates liner corrosion at every point of contact. We include waterproofing recommendations in every Gelco inspection, and we’ll tell you if your existing crown needs repair before waterproofing will help. Call (336) 863-3889 for an assessment.
