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 Howell, NJ | Hearthstone Chimney Co.
We provide independent Gelco chimney cleaning and repair across Howell’s 1980s-era subdivisions, where most homes rely on factory-built prefab fireplaces rather than traditional masonry. The one thing that makes our Gelco work here different: we’ve spent decades tracing the exact failure chain that Howell’s humid inland climate and heavy softwood burning inflict on these aging metal systems - rusted chase covers, degraded inner liners, and Class A flue leaks that generic sweeps often misdiagnose. Call (609) 657-3371 for a free estimate; estimates come with photos you can see and a plain-English verdict.
Why Howell Residents Choose Us for Gelco Service
Russell Haines picked up his trade fundamentals at Los Angeles Trade-Technical College before heading east and building Hearthstone Chimney Co. into what it is today - over 42 years of answering the phone with a live person, background-checking every technician, and walking every finished job himself before calling it done. That old habit hasn’t broken yet.
We know Gelco prefab systems because we’ve worked on hundreds of them across Howell and the surrounding townships. Our trucks carry OEM-compatible chase covers, storm collars, and liner panels sized for Gelco’s zero-clearance units - the GV series wood fireplaces, the gas direct-vent models from the 1990s build-out, and the Class A metal flue assemblies that run through those enclosed wood-framed chases. When a Gelco sales & service question comes up, we don’t guess at clearances or substitute aftermarket parts that compromise the tested assembly. We measure, match, and stand behind it with the 90-Day Done Right Promise in writing.
Howell’s housing stock demands this specificity. The ranch homes and split-levels off Route 9, the colonials near Ramtown - these weren’t built with brick hearths. They were built with factory-engineered systems that require factory-engineered solutions. We provide those solutions without the factory markup or the factory runaround.
Common Gelco Chimney Cleaning Problems We Solve in Howell
- Rust-through chase covers in Route 9 and Ramtown subdivisions. Howell’s humid Monmouth County climate eats through thin galvanized sheet metal in 15-20 years. Once water funnels through that rusted cover, it hits the inner flue liner directly and starts a rust-and-gap failure sequence. We replace with OEM-compatible covers that fit the tested clearance envelope, not generic hardware-store lids that sit proud and leak worse.
- Deteriorating inner liners on 30-50 year old Gelco prefab fireboxes. The metal inner panels warp, crack, or perforate after decades of burn cycles. In Howell, where winters run colder than the Shore and fireplaces see real use, this degradation accelerates. We inspect with a Level 2 camera, show you the photos, and give an honest verdict: repair the component if the shell’s intact, replace the unit if it’s not.
- Failed storm collars and flashing at roof penetration. This leaks into ceilings and gets misdiagnosed as a roof problem half the time. On Howell’s prefab chases, the storm collar seals the Class A flue pipe where it exits the chase top. When it fails - and it does, regularly, on 1980s and 1990s installs - water tracks down the pipe and into the chase framing. We trace the real source, document it with photos, and fix the flue system, not the shingles.
- Creosote glaze from Pine Barrens softwood burning. Howell sits at the northwestern edge of the Pine Barrens, and plenty of residents burn locally sourced pine and mixed softwoods. That fuel choice plus cold inland winters equals heavy creosote loads. Stage 3 glazed creosote won’t budge with a standard brush. We use mechanical de-glazing and chemical treatment where needed, and we’ll tell you straight if your burn habits push you to twice-a-season cleaning.
- Compromised Class A flue joints from thermal cycling. Howell’s temperature swings - below freezing nights, 50-degree days through winter - expand and contract metal flue pipes at every joint. After 35 years, the locking seams loosen, the sealant degrades, and you get draft problems or worse. We inspect the full vertical run, reseal where possible, and replace sections where the metal itself has fatigued.
Gelco Service in Howell: What Local Conditions Mean for Your Equipment
Howell’s rapid suburban build-out from roughly 1975 through the mid-1990s produced something unusual for a New Jersey township of its age: virtually no pre-war housing stock, and almost no traditional masonry chimneys. What went up instead were zero-clearance prefabricated metal fireplace systems by the thousands - Gelco units among them - tucked into wood-framed chases and vented through Class A metal flue pipes. That single fact changes everything about how we approach Howell service area calls.
We’re not inspecting brick and mortar. We’re inspecting factory-engineered assemblies with tested clearances, metal-to-metal joints, and chase enclosures that rot from the inside out when water gets past a rusted cover. The tools change - camera scopes that navigate metal elbows, not masonry flues. The access changes - we’re often working from attic spaces or rooflines to reach the chase top, not dropping a brush down a straight brick shaft. And the failure points change - we’re hunting rust patterns, liner gaps, and storm-collar degradation, not spalling brick or eroded mortar joints.
This matters for Gelco owners specifically because these units are now 30-50 years old. The chase covers installed in 1987 were never meant to last until 2025. The inner liners rated for 25 years of normal use have seen 35 years of Howell’s colder-than-coastal winters. When we arrive at a home off Route 9 or out by Ramtown, we’re not surprised by what we find. We’ve seen that failure chain before. We’ll document it with photos, explain it in plain English, and fix it properly - or tell you honestly when replacement is the only safe path.
Gelco Models & Products We Service in Howell
We work on the full range of Gelco factory-built systems found in Howell’s 1975-1995 housing stock:
- Gelco Heat-N-Glo / Heatilator competitor zero-clearance wood prefab models. The builder-grade units from the 1980s-1990s suburban boom, common in Howell’s planned subdivisions.
- Gelco GV series factory-built wood fireplaces. Heavier-duty prefab units with specific liner panel configurations and damper assemblies.
- Gelco gas direct-vent prefab fireplaces. 1990s installs, often in family rooms and master bedroom additions, with sealed combustion and specific venting requirements.
- Gelco Class A metal flue pipe and chimney chase systems. The venting backbone of every prefab install - and the component most vulnerable to Howell’s climate-driven rust-and-leak cycle.
Our trucks stock OEM-compatible chase covers, storm collars, liner panels, and damper hardware sized to Gelco’s original clearances. Aftermarket parts that don’t match the tested assembly? We don’t use them. The zero-clearance certification depends on exact fit. Cut corners there and you’ve cut the safety margin that made the unit legal to install in the first place.
Gelco Service Pricing in Howell
Our $89 Seasonal Tune-Up covers a full sweep and basic inspection for Gelco wood-burning prefab units in normal condition. Level 2 camera inspections - the kind we recommend for any Howell home with a 30+ year old Gelco system - run higher, and we quote upfront before booking. Firebox repair, chase cover replacement, and liner panel work are priced by the specific components and labor involved; no two aging Gelco units fail identically, so we don’t pretend they do.
What drives cost: accessibility of the chase top, extent of rust or liner degradation, and whether we’re performing Chimney Repair in Howell or recommending full unit replacement. Every estimate includes photo documentation of what we found, a plain-English explanation of why it matters, and a written quote with no surprises on the bill. We also honor a permanent 5% Senior and Veteran discount, and we offer $50 off any repair over $250.
For an exact quote on your Gelco system, call (609) 657-3371. Estimates are free, and we bring the camera to every appointment.

FAQs - Gelco Chimney Cleaning in Howell
You don’t, not without a Level 2 camera inspection. The inner liner on a 35-40 year old Gelco wood prefab is past its designed service life, and thermal cycling plus any past water intrusion from a compromised chase cover can warp, crack, or perforate the metal. We run a camera scope through the full flue path, photograph every surface, and show you exactly what we’re seeing. If the liner’s intact, we’ll document that. If it’s not, we’ll explain your repair and replacement options with real numbers. Call (609) 657-3371 to schedule - estimates are free.
Because it was built from thin galvanized steel in an era when 15-20 years was considered acceptable service life for a disposable component. Howell’s humid inland climate accelerates that rust, especially on chase tops that pond water or sit in shade. The replacement covers we install are heavier-gauge, OEM-compatible, and properly pitched to shed water. We also inspect the storm collar and flue seal as part of the job - a chase cover replacement without addressing the collar is half a fix. Call (609) 657-3371 for pricing on your specific chase configuration.
Yes. Pine and softwood produce more creosote per cord than hardwood, and Howell’s colder inland winters mean longer burn seasons with more cycles. For active burners using softwood, we often recommend sweeping twice per season - once mid-winter, once at shutdown - rather than the standard annual schedule. Stage 3 glazed creosote, which standard brushing won’t remove, is more common in these conditions. We can assess your current buildup during a camera inspection and recommend a cleaning frequency based on what we actually find, not a calendar guess. Call (609) 657-3371 to book.
We service both. Gelco’s gas direct-vent prefab fireplaces from the 1990s build-out require different diagnostics - we’re checking sealed combustion chambers, vent terminal clearance, and gas valve operation rather than creosote and liner condition - but our technicians are trained on both fuel types. The same photo-documentation and plain-English verdict applies. If your gas Gelco unit is malfunctioning, not lighting properly, or showing soot patterns it shouldn’t, we’ll trace the cause and fix it or tell you honestly if replacement makes more sense. Call (609) 657-3371 for an exact quote.
A sweep only removes combustible deposits. It doesn’t repair rusted metal, cracked liner panels, or a compromised firebox shell. If your Gelco unit has structural or safety issues, sweeping and using it is not a safe option. That said, “full rebuild” gets thrown around too easily by contractors who don’t want to diagnose precisely. We camera-inspect first, show you the photos, and explain whether component repair (chase cover, storm collar, liner panels) will restore safe operation or whether the firebox shell itself is too far gone. Find what’s wrong, fix it properly, stand behind it - that’s the whole job. Call (609) 657-3371 for a second opinion; we’ll match any written estimate and give you the straight story.
