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 Trenton Homeowners Choose Gelco Chimney Cleaning
We provide Gelco service in Trenton, NJ, with independent chimney cleaning, repair, and installation, with technicians who know these systems from hands-on field work, not from a training manual. Our Gelco service includes Level-2 camera inspections with photos you can see, creosote removal from stainless steel liners, cap and crown replacement, and honest repair-versus-replace guidance backed by our 90-Day Done Right Promise in writing. We are not affiliated with or authorized by Gelco - we are an independent service company that has worked on Gelco-brand chimney systems in Trenton for years, and our expertise comes from the jobs we’ve done, not from any manufacturer partnership.
Trenton’s dense stock of late-19th and early-20th-century factory-worker row homes in Chambersburg, South Trenton, and the Wilbur section present a particular challenge for chimney systems. These original masonry chimneys were sized and drafted for coal-burning furnaces, then converted to gas or oil mid-century without proper relining. The result is a city full of undersized, unlined, or abandoned flues where our Chimney Cleaning & Sweep services pair with Gelco stainless steel liners and multi-flue caps, which are often the right retrofit - and where our familiarity with Gelco construction matters more than generic sweep know-how.
Call (856) 519-0832 to speak with a live person about your Gelco system. We’re here 24 hours a day, 7 days a week.
Why Trust Hearthstone Chimney Co. for Your Gelco Chimney Cleaning?
We’ve been serving local communities for over 42 years, and in that time we’ve developed specific familiarity with how Gelco products perform in the field. Russell Haines, our owner, grew up in Los Angeles and picked up his trade foundation at Los Angeles Trade-Technical College before the work pulled him east. He’s been cleaning and inspecting chimneys for going on two decades now, and his crew has worked jobs from the rowhouses near Broad Street Station to Gelco Chimney Cleaning in Robbinsville, NJ and older colonials throughout Trenton’s Chambersburg neighborhood - the kind of masonry that demands patience more than speed. Russell is known for straightforward inspections: he tells you what he found, what it means, and what it will cost to fix, nothing added and nothing left out.
Our technicians are background-checked, uniformed, and carry the tools and parts to complete most Gelco jobs in a single visit. We document every inspection with photos and a plain-English verdict, and we back every job with the 90-Day Done Right Promise - in writing, no arguing. If it’s not right, we make it right. That’s the Keystone Standard: Krafted right, Every time, Your home first, Standing behind it.
We source professional-grade materials from industry-trusted brands including Gelco, DuraFlex, HeatShield, Olympia Chimney, Famco, and Copperfield. No builder-grade substitutes. When we recommend a repair or replacement on your Gelco system, you get camera evidence you can see for yourself, and we’ll tell you plainly when work can safely wait.
Common Gelco Chimney Cleaning Problems We Fix in Trenton
- Creosote accumulation in Gelco stainless steel liner systems. Trenton’s older homes often have poor draft due to oversized flues originally built for coal. When a Gelco stainless steel liner is retrofitted into one of these chimneys without proper sizing verification, creosote can build up faster than expected. We see this regularly in the row homes around Chambersburg where mid-century conversions left chimneys struggling to vent modern gas appliances. Our Level-2 inspection identifies the accumulation pattern, and we clean with rotary methods safe for Gelco’s 316Ti stainless steel alloy.
- Rusted or deteriorated Gelco multi-flue caps. Trenton sits in the Delaware River valley with pronounced freeze-thaw cycling each winter. That cycling accelerates spalling of historic brick and also attacks the finish on metal caps. Gelco multi-flue caps in Trenton often show rust at the welded seams first, then at the mesh screening. Once water gets through, it leaks into the flue, carries creosote acids down the liner, and invites animal nesting. Our tech recently serviced a Gelco multi-flue cap in Trenton that had rusted through, allowing water to leak into the flue and causing a partial damper seizure. We removed the old cap, cleaned out the debris, replaced it with a new Gelco-compatible cap, and performed a Level-1 inspection to ensure no further damage. The homeowner was relieved to have the leak stopped before it caused more expensive masonry damage.
- Cracked or spalling Gelco chimney crowns. Gelco crowns are poured concrete or pre-formed units meant to shed water from the chimney top. In Trenton’s climate, water infiltrates hairline cracks, freezes overnight, and widens them through the winter. By March, a crown that looked sound in October can be channeling water directly into the chimney structure. We inspect Gelco crowns as part of every service and repair or replace based on what the camera shows, not guesswork.
- Corroded or stuck Gelco dampers. Gelco dampers seal the flue when the fireplace or appliance is not in use. When moisture enters through a failed cap or crown, the damper plate and frame corrode. In Trenton’s attached row-home blocks, where a single exterior stack often contains four stacked clay-tile flues, a stuck damper in one unit can mean carbon monoxide or smoke finding paths into neighboring units. We free, repair, or replace Gelco dampers and test the seal with a smoke pencil before we leave.
- Improper Gelco liner sizing in converted flues. This is the Trenton-specific issue we see most. Original coal flues in these row homes are far too large for modern gas or oil appliances. A Gelco stainless steel liner installed without proper downsizing creates sluggish draft, condensation in the flue, and accelerated creosote formation. Our inspection measures the appliance output against the liner diameter and documents whether the match is correct. If the liner is wrong for the appliance, we say so, and we explain what sizing correction would involve.
Gelco Parts & Our Repair-vs-Replace Approach
We source OEM Gelco parts when available for critical components like caps and crowns. For many applications, high-quality aftermarket alternatives from our trusted brand partners are equally durable and more cost-effective. We don’t default to replacement because it’s easier. We provide an honest assessment of whether repair or full replacement is the better long-term value for your Gelco system, and we show you the camera evidence so you can see what we see.
We stock Gelco-compatible caps, crown repair materials, and liner cleaning equipment locally for fast turnaround. Most Gelco jobs in Trenton are completed in a single visit. No-hassle upfront pricing means the number on the estimate is the number on the invoice. Call (856) 519-0832 for a free estimate.
Our Gelco Service Process - Step by Step
- 1
Diagnosis with Level-2 camera inspection. We insert a high-resolution camera into your Gelco flue system and photograph every joint, every liner section, every damper condition. You see the photos. We explain what they mean in plain English. No jargon, no scare tactics.
- 2
Repair or install with warranty-safe methods. We use techniques and parts that maintain any remaining Gelco warranty where applicable, and we document our work with photos. For liner cleaning, we use rotary systems rated safe for Gelco’s 316Ti stainless steel. For cap or crown replacement, we verify proper fit and clearance.
- 3
Test and verify. We run a smoke test or draft test to confirm your Gelco system vents properly after our work. Dampers are cycled and checked for full closure. Caps are inspected for secure mounting and proper mesh clearance.
- 4
Warranty documentation. You receive written documentation of the inspection findings, the work performed, and our 90-Day Done Right Promise. If something’s not right, we come back. No paperwork to dig up, no argument.

Once per year for wood-burning systems, per NFPA 211. Gas and oil appliances with Gelco liners should be inspected annually and cleaned as needed based on inspection findings. In Trenton’s row-home blocks, where shared chimney stacks mean one neighbor’s problem can affect others, annual inspection is the safer practice. Call (856) 519-0832 to schedule.
Yes. We often install high-quality aftermarket caps that match or exceed Gelco specifications, particularly when Gelco OEM caps are backordered or discontinued. We verify proper fit, mesh sizing, and clearance before mounting, and we warranty our installation work regardless of cap brand.
We repair when the crack is surface-level and the crown structure is sound. We replace when cracks penetrate through, when spalling has compromised the concrete, or when the crown is improperly sloped and channels water inward. The camera inspection and photos show you which category you’re in.
Gelco’s 316Ti stainless steel liners resist corrosion well but can be scratched by overly aggressive tools. We use rotary cleaning systems with poly or wire brushes selected for the liner diameter and creosote type, never generic rods jammed through blindly.
Moisture is the primary cause. Water enters through a failed cap, corrodes the damper plate and pivot, and eventually seizes the mechanism. Creosote buildup on the damper edges can also cause sticking. We identify the root cause, not just the symptom, so the repair lasts.
