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.

We’ve been working on Farmingdale chimneys for decades. The village’s post-war Cape Cods and ranch homes along streets like Melville Road and Conklin Street have chimney systems built for a different era of heating, and that mismatch between old flue sizing and modern appliances is something we address on nearly every call. Our technicians are background-checked, uniformed, and carry the camera equipment and professional-grade materials to complete most jobs without a return trip.
Why Hearthstone Chimney Co. Is Farmingdale’s Preferred Chimney Cleaning & Sweep Company
Farmingdale homeowners know their chimneys. Many have lived in the same house on the South Shore for thirty or forty years, and they’ve seen enough contractors come and go to spot a shortcut from across the yard. We’ve answered the phone with a live person for over 42 years, and we plan to be here when the next generation needs us. That changes how we work.
Our reputation here rests on documentation. Every Level 2 inspection ends with photos you can see and a plain-English verdict - no jargon, no scare tactics, just what we found and what it means. The 90-Day Done Right Promise backs every job in writing. If it’s not right, we make it right. No paperwork to dig up, no arguing about fine print.
Dispatch and scheduling are coordinated from our New York City office, but crews serve Farmingdale locally. We know the difference between a village-center colonial near the Farmingdale LIRR station and a split-level off Route 110, and we know how the South Shore’s salt-laden air hits each one differently. Most jobs finish in one visit, with upfront pricing agreed before we start.
Our Chimney Cleaning & Sweep Services in Farmingdale
Level 1 Inspection
A Level 1 inspection is the baseline for any Farmingdale chimney, and it’s what we recommend annually for systems that haven’t changed and are performing normally. We examine the readily accessible portions of the chimney exterior, interior, and flue, checking for creosote buildup, obstructions, and basic structural soundness. For the thousands of mid-century homes near Farmingdale High School or along Main Street, this annual check often catches crown cracks or mortar deterioration before South Shore storms turn them into ceiling stains.
Level 2 Inspection
Level 2 is where we bring in the camera, and it’s essential for Farmingdale’s housing stock. We run a high-resolution video scanner the full length of the flue, documenting every joint, every crack, every glazed creosote deposit. This is the inspection that reveals what we find on nearly every call here: a 6- or 7-inch clay tile flue still serving a converted gas boiler with no stainless steel liner insert. The oversized flue can’t maintain proper draft. Corrosive condensate soaks into aging mortar joints. Carbon monoxide backdraft becomes a real risk. You get the photos, you get the plain-English verdict, and you get an honest assessment of what can wait versus what can’t.
Creosote Removal
Creosote buildup is the leading cause of chimney fires nationwide, and Farmingdale is no exception. We remove first-, second-, and third-degree creosote using professional-grade brushes, chains, and chemical treatments matched to the deposit stage. Third-degree glazed creosote - the shiny, tar-like layer that forms when wood burns inefficiently - requires specialized removal. We don’t guess. We camera-inspect first, identify the stage, and price the work upfront. No surprises on the bill.
Soot Removal
Soot accumulation reduces draft efficiency and can release odors during humid Farmingdale summers. Our soot removal service cleans the firebox, smoke chamber, and flue to restore proper airflow and eliminate the musty smell that South Shore humidity can amplify. For oil-to-gas conversion homes, we also check for sulfur residue that accelerates liner corrosion.
Annual Sweep
The National Fire Protection Association recommends annual sweeping for all wood-burning systems, and we extend that advice to any Farmingdale chimney serving a fuel-burning appliance. Our annual sweep includes the Level 1 inspection, debris removal, and a written condition report. Many of our Farmingdale customers on streets near Allen Boulevard or the village center book these in late summer, before the first cold snap has everyone calling at once.
Fireplace Cleaning
Fireplace cleaning addresses the visible and hidden components: firebox refractory panels, damper assembly, smoke shelf, and hearth. We remove ash, creosote, and animal nesting material, then inspect for cracks or deterioration that could send heat into surrounding framing. For Farmingdale’s older homes with original masonry fireplaces, this service often reveals the same crown and flashing issues we see on heating-system flues.

Trusted Brands We Service in Farmingdale
We don’t use builder-grade substitutes. Our trucks carry professional-grade materials from DuraFlex, HeatShield, Gelco, and Olympia Chimney - brands that meet or exceed NFPA standards and hold up to Long Island’s marine climate. When a Farmingdale chimney needs a stainless steel liner insert to properly serve a converted gas appliance, we size and install DuraFlex or Olympia Chimney liners engineered for the specific appliance BTU output and flue configuration. We stock common cap and crown repair materials locally, so most Farmingdale repairs don’t wait on shipping.
Common Chimney Cleaning & Sweep Problems We See in Farmingdale Homes
- Storm-lifted caps and cracked crowns after nor’easters. Farmingdale’s exposed South Shore position means wind-driven rain and salt spray hit chimney crowns harder than inland markets. After a nor’easter rolled off the Atlantic last season, a homeowner on Melville Road in the village center called about a water stain spreading across the ceiling beside the chimney. Our tech found the storm had lifted a displaced chimney cap and cracked the crown on their 1950s Cape Cod, letting rain run down a 7-inch clay tile flue that was still serving a converted gas boiler with no liner insert. We reset the cap and rebuilt the crown, then recommended a stainless liner insert sized to the appliance so the flue could actually hold draft instead of soaking the mortar in condensate.
- Failing Hurricane Sandy patch repairs. Sandy’s 2012 strike dislodged or cracked crowns and caps across Nassau County’s South Shore. The patch repairs from a decade ago are now failing themselves. We regularly find a second-generation crown crack under a homeowner’s “already fixed” assumption. A proper rebuild with professional-grade crown sealant - we use HeatShield for many of these - lasts longer than the quick patches that followed the storm.
- Corroded flashing from salt-laden marine air. The same humidity that makes Farmingdale summers uncomfortable accelerates flashing corrosion at the roofline. A storm-driven leak that looks like a cracked crown often traces back to failed step flashing or counterflashing. We camera-inspect to confirm the source before recommending repair, so you’re not paying for a crown rebuild when the real problem is eight inches lower.
- Oversized clay tile flues serving converted gas appliances. This is the Farmingdale signature problem. Nassau County adopted oil-fired boiler sizing in the 1950s and 1960s, and when Long Island’s conversion wave switched those homes to gas, many were never fitted with the required stainless steel liner insert. The 6- or 7-inch flue can’t hold draft. Corrosive condensate deposits directly into aging mortar joints. Carbon monoxide backdraft risk is real. We find this on nearly every call here, and we document it with photos you can see.

FAQs - Chimney Cleaning & Sweep in Farmingdale
Yes. Even gas appliances produce corrosive condensate, and an unused chimney can harbor moisture damage, animal nesting, or structural deterioration that you won’t notice until there’s a leak or draft failure. In Farmingdale’s humid, salt-laden climate, mortar joints and flashing corrode faster than inland markets, so annual inspection catches problems before they become expensive repairs. Call (934) 348-4832 for a free estimate - estimates are free, and the camera inspection shows you exactly what we find.
Your chimney was built in the 1950s or 1960s for an oil-fired boiler, and oil burners needed large flues to handle their exhaust volume. When Long Island converted to gas, many installers never pulled permits or added the stainless steel liner insert that a modern gas appliance requires. The oversized flue can’t maintain proper draft, so corrosive condensate deposits into your aging mortar joints while carbon monoxide backdraft risk increases. This is the single most common condition we find in Farmingdale’s mid-century homes, and it’s why we camera-inspect every system we touch. Call (934) 348-4832 - we’ll show you the photos and explain your options.
Look for three things: water stains on the ceiling near the chimney (indicating crown, cap, or flashing failure), debris or animal nesting in the firebox or at the damper, and any sulfur or musty odor when you open the damper. But here’s the critical one for Farmingdale - if your home converted from oil to gas and you’ve never had a camera inspection, you may have an unlined oversized flue creating a carbon monoxide risk you cannot see from the living room. We recommend a professional Level 2 inspection before the first burn. Call (934) 348-4832 to schedule.
Third-degree creosote looks like shiny, tar-like black glass coating the flue walls. It forms when wood burns at low temperatures or with insufficient airflow, and it’s the most dangerous stage because it ignites at lower temperatures and burns intensely. You cannot safely determine the stage by looking up from the firebox. We run a camera to identify the deposit type, then match the removal method - rotary chains for glazed creosote, chemical treatment for severe buildup - to what we actually find. Call (934) 348-4832 for an inspection and exact quote.
We do both, and in Farmingdale they’re often related. A leak that shows as a ceiling stain frequently traces to a cracked crown, displaced cap, or corroded flashing - all conditions we diagnose during our inspection. We rebuild crowns with professional-grade materials, reset or replace caps, and repair flashing. If the leak has damaged the flue liner, we install stainless steel inserts from DuraFlex or Olympia Chimney sized to your appliance. The camera inspection determines whether you’re looking at a $400 cap repair or a $3,000 liner replacement, and we show you the evidence before you decide. Call (934) 348-4832 for a free estimate.
