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 Cleaning in Hicksville, NY | Hearthstone Chimney Co.
We provide independent Chimney Cleaning & Sweep - Hicksville, cap replacement, and damper service across Hicksville - not as an authorized dealer, but as a crew that has pulled apart enough corroded Gelco hardware on post-war Cape Cods to know why these parts fail here faster than almost anywhere else on Long Island. The sulfur-based oil soot that coats Hicksville’s clay-tile flues eats Gelco cap screens and damper gaskets from the inside out, even in homes that never burned a log. Call (516) 259-3797 for a free estimate - we’ll show you exactly what your flue looks like inside.
Why Hicksville Residents Choose Us for Gelco Service
Russell Haines picked up the fundamentals at Los Angeles Trade-Technical College before deciding chimneys were the kind of problem he wanted to spend a lifetime solving. That was over 42 years ago. Since then, he and our crew have spent the better part of their careers keeping fireplaces - and boiler flues - honest on the older Cape Cods and colonials off Broadway Mall in Hicksville. We know the hamlet’s housing stock because we’ve been inside hundreds of them.
We don’t claim manufacturer authorization. Our Gelco sales & service credibility comes from documented tear-outs and rebuilds: photos you can see, a plain-English verdict, and the 90-Day Done Right Promise in writing if we touch it. We carry OEM Gelco caps, dampers, and mounting hardware alongside quality stainless aftermarket equivalents sized to Hicksville’s common flue dimensions. When a component is still structurally sound, we repair or reseat it. We’ll tell you plainly when corrosion has ended its life.
A live person answers our phone 24 hours a day, 7 days a week. Our technicians are background-checked, uniformed, and complete most jobs in a single visit. No-hassle upfront pricing means the number on the estimate is the number on the invoice.
Common Gelco Chimney Cleaning Problems We Solve in Hicksville
- Gelco cap screens corroded through by sulfur-oil soot. Hicksville’s post-WWII flues vented oil boilers for decades, and that acidic residue etches stainless screens from the inside while homeowners assume “no fireplace means no chimney problem.” We replace with OEM or upgraded stainless mesh.
- Top-sealing damper gaskets torn or springs seized. Oil-heat cycling - on, off, on, off - for 40+ years hardens Gelco damper seals and fatigues springs. During nor’easters, a failed damper lets wind-driven rain straight down the flue. We reseal or replace with hardware sized to your flue.
- Multi-flue cap mounting hardware rusted through. Nassau County’s freeze-thaw cycles spall exterior brick on Cape Cod and ranch chimneys, and the resulting vibration and moisture rust through Gelco mounting brackets. We’ve found caps lifted or blown completely off after winter storms.
- Cap screens clogged with dense oil soot, not wood creosote. This residue is chemically distinct - stickier, more acidic, and harder on clay tile. A clogged screen reduces draft silently, masking cracked liners until a gas-conversion inspector flags the flue as unfit.
- Crown and flashing deterioration hidden beneath intact-looking caps. Gelco caps outlast the masonry they sit on in Hicksville. We pull the cap, photograph the crown, and tell you whether the cap can be reseated or the crown needs work first.
Gelco Service in Hicksville: What Local Conditions Mean for Your Equipment
Hicksville’s housing stock is overwhelmingly post-WWII Cape Cods and ranches built between the late 1940s and mid-1960s during Long Island’s suburban boom - the vast majority with chimneys designed to exhaust oil-fired boilers, not wood-burning fireplaces. As these 70-year-old flues deteriorate from acidic sulfur-soot deposits, and as homeowners convert from heating oil to natural gas or heat pumps, demand for chimney cleaning, inspection, and stainless-steel relining is exceptionally concentrated here in a way it simply isn’t in newer or more gas-dominant markets.
Here’s what that means for Gelco equipment specifically. The sulfur-based oil soot that coats Hicksville’s clay-tile flues is not the dry, flaky creosote of wood-burning chimneys. It’s acidic, condensing, and migrates upward through every gap in a cap screen or damper seal. Gelco stainless hardware - quality stuff, made to last - still corrodes faster in this chemistry than in a wood-burning flue. We’ve pulled Gelco caps off Jerusalem Avenue ranches where the underside of the screen looked like it had been soaked in battery acid, while the homeowner had no idea their boiler flue was producing anything more harmful than warm air. That distinction shapes every sweep we run in the hamlet. The chimney doesn’t care what you hoped it was - it shows you what it is.
Gelco Models & Products We Service in Hicksville
We work on the full Gelco line found in Hicksville service area homes: single-flue and multi-flue stainless steel chimney caps, top-sealing damper assemblies, and masonry crown and flashing components. Our trucks stock common Gelco cap sizes for the 8×8, 8×12, and 13×13 flue dimensions we see repeatedly in 1950s Cape Cods and ranches. For less common sizes or custom configurations, we order OEM Gelco or fabricate stainless equivalents - no builder-grade substitutes.
Our Hicksville Chimney Repair stance is simple. If a Gelco cap frame is sound and only the screen or mounting hardware has failed, we replace those components and reseat the cap. If the frame itself is corroded through or the flue liner beneath it is spalled and cracked, we’ll show you the camera footage and explain why a full cap replacement - or cap plus reline - is the honest call. No upsell. No surprises on the bill.

FAQs - Gelco Chimney Cleaning in Hicksville
Your boiler flue still vents through that chimney, and Hicksville’s oil-heating history means that flue is coated in acidic sulfur soot that corrodes Gelco cap screens and damper seals from the inside out. We’ve replaced caps on homes where the homeowner never knew they had a chimney problem until water started coming down the flue or a conversion inspector flagged the venting. Call (516) 259-3797 for an exact quote - estimates are free.
The residue is chemically different. Wood creosote is flammable and builds up in layers; Hicksville’s oil soot is acidic, condensing, and etches clay tile while corroding metal components. Our brushes and techniques account for that chemistry, and we inspect Gelco hardware specifically for acid corrosion rather than heat fatigue. Call (516) 259-3797 for an exact quote - estimates are free.
Annually, before December. Nassau County’s freeze-thaw cycles and nor’easters punish exterior masonry and cap mounting hardware; an inspection in September or October catches corrosion, gasket wear, or lifted caps before heating season stress and winter storms compound the damage. Call (516) 259-3797 for an exact quote - estimates are free.
A corroded cap contributes to liner damage by letting rain and debris enter, but it’s usually a symptom of the same acidic conditions that already spalled the clay tile. The cap didn’t cause the liner failure alone - the oil soot did - but a failed cap accelerates it. We document both with camera footage so you understand the full picture before deciding on cap replacement, reline, or both. Call (516) 259-3797 for an exact quote - estimates are free.
Both. We stock OEM Gelco caps and mounting hardware, and we also carry quality aftermarket stainless equivalents. We match the solution to your flue condition and budget - OEM when the fit and finish matter, aftermarket when the application is straightforward and the savings are real. We’ll tell you which we’re recommending and why before any work starts.
