Malverne sits three miles inland from the South Shore, square in the nor’easter track. That means your chimney takes wind-driven rain and salt-laden air straight on the brick. The freeze-thaw cycle here pumps water into micro-cracks, widens them winter after winter. We’ve seen it. We’ve measured it. We’ve fixed it. That’s why local expertise matters: a technician who doesn’t know Nassau County’s hard groundwater, or the village’s oil-to-gas conversion wave, or the specific code violations common to Malverne’s shared-flue chimneys, will miss what matters.

Why Hearthstone Chimney Co. of New York City Is Malverne’s Preferred Chimney Cleaning & Sweep Company
We’ve worked Malverne chimneys since before PSEG Long Island ran natural gas lines through Nassau County neighborhoods. Homeowners here remember when their oil truck came every autumn. Now they’re converting to gas, and they’re discovering what we’ve known for decades: that oversized terracotta flue liner, sized for high-heat oil combustion, becomes a hazard with lower-temperature gas exhaust. We document every inspection with photos and a plain-English verdict. The homeowner sees what we see. No jargon, no surprises.
Our 90-Day Done Right Promise governs every job in ZIP 11565. In writing. No paperwork to file, no arguing. If it’s not right, we come back. That promise has been our standard since 1984, and we intend to be here in thirty more years to honor it.
A live person answers our phones every hour of every day. Not a callback queue. Not an app. When a Malverne homeowner smells smoke in the living room at 10 p.m. on a February night, someone picks up. Our technicians are background-checked, uniformed, and carry professional-grade materials from DuraFlex, HeatShield, and Gelco. Most jobs finish in one visit. The number on the estimate is the number on the invoice.
We recently serviced a 1930 Tudor on Hempstead Avenue, Malverne, where the homeowner had just converted from oil to gas. Our Level 2 Inspection revealed a single flue serving both the fireplace and new gas boiler, a code violation. We lined the boiler flue with a 5-inch DuraFlex stainless liner and sealed the fireplace flue with a HeatShield crown repair, ensuring both systems met Nassau County code. The homeowner had the photos, the verdict, and the permit paperwork before we packed our tools.
Our Chimney Cleaning & Sweep Services in Malverne
Level 1 Inspection
A Level 1 Inspection is the annual check every Malverne homeowner with a working fireplace or heating appliance should schedule. We examine the readily accessible portions of your chimney’s interior and exterior, looking for creosote buildup, obstructions, and structural soundness. For the Cape Cod and bungalow stock near West Hempstead’s border, where chimneys often serve both a modest fireplace and a basement boiler, this basic sweep catches developing problems before they require a permit job. The inspection takes about an hour. You’ll get a verbal summary on site, with photos if we spot anything that needs attention.
Level 2 Inspection
Level 2 Inspection is where our Chimney Cleaning & Sweep team does its deepest work in Malverne. We use a high-resolution camera to scan the full length of the flue, documenting every cracked liner tile, every gap in mortar joints, every trace of glazed creosote. This is the inspection we recommend - and often insist upon - for any home in the oil-to-gas conversion pipeline. Malverne’s high concentration of single-flue chimneys shared by both fireplace and oil burner means that every conversion triggers a mandatory code-required separation and reline, a job uniquely common here. The camera doesn’t lie, and the photos don’t vanish. You see what we see. The verdict comes in plain English, not code-speak. A Level 2 Inspection in Malverne runs $280-$450 depending on flue accessibility and the number of appliances served.
Creosote Removal
Creosote glazing is the hidden danger in Malverne’s converted chimneys. When a homeowner switches from oil to gas, the oversized terracotta flue that once handled 600°F oil exhaust now carries 300°F gas exhaust. The lower temperature means incomplete combustion. Moisture condenses. Creosote hardens into a glazed, tar-like coating that standard brushes won’t touch. We’ve pulled glazed creosote deposits an inch thick from Malverne chimneys that “passed” a visual inspection. Our technicians use mechanical whipping tools and professional-grade solvents to break that glaze before it becomes a chimney fire hazard. Creosote removal as a standalone service in Malverne typically runs $180-$340; when bundled with a Level 2 Inspection, we discount the combined price.
Soot Removal
Soot accumulation is the everyday enemy of draft efficiency. In Malverne’s older masonry chimneys, where mortar joints have softened from decades of groundwater seepage, soot combines with crumbling mortar to form dense, obstructive deposits. We see this especially in the pre-WWII colonials near the village center, where chimneys have never been relined. Our soot removal service restores proper draft, reduces smoke backup into living spaces, and gives us a clean view of the flue walls for inspection. Most soot removal jobs in Malverne finish in under two hours and cost $150-$280.
Annual Sweep
The annual sweep is preventive maintenance done right. For Malverne homeowners who burn wood even occasionally, NFPA 211 recommends yearly service. We schedule these sweeps during daylight hours, work cleanly with drop cloths and HEPA vacuums, and leave no trace except a swept chimney and a written condition report. Our $89 Seasonal Tune-Up covers the sweep and basic Level 1 inspection for standard fireplaces. For heating-plant flues or combined fireplace-boiler setups, we quote upfront based on what we find.
Fireplace Cleaning
Fireplace cleaning in Malverne addresses the firebox, smoke chamber, and damper assembly - the parts you see and the parts you don’t. Smoke chambers in 1930s-1950s construction often have corbelled brick that collects creosote in angles a standard brush misses. We hand-scrape these chambers, clean and lubricate dampers, and inspect the firebox lining for heat damage. A clean fireplace draws better, smells better, and burns safer. Fireplace cleaning typically runs $120-$220 as a standalone service.

Trusted Brands We Service in Malverne
We stock professional-grade materials from DuraFlex, HeatShield, and Gelco for Malverne jobs, with Copperfield and Famco hardware on our trucks for our Chimney Cap & Crown in Malverne and flashing repairs. These are not builder-grade substitutes. A DuraFlex stainless liner carries a lifetime warranty when we install it. HeatShield’s cerfractory resurfacing system lets us restore a deteriorated smoke chamber without rebuilding it. We keep these materials on hand because Malverne’s chimney problems don’t wait for shipping. When our technician finds a cracked crown on a February afternoon, we fix it then. Not next week. The turnaround matters when nor’easter season is active.
Common Chimney Cleaning & Sweep Problems We See in Malverne Homes
- Creosote glazing from incomplete combustion in oversized terracotta flues after oil-to-gas conversion. The flue that worked fine for oil becomes a condensation trap for gas exhaust. Glazed creosote reduces draft and can cause carbon monoxide spillage into living spaces. We catch this with Level 2 camera inspection, then remove it with mechanical tools.
- Spalling brick crowns from freeze-thaw cycles. Malverne’s location in the nor’easter track means repeated wet-dry and freeze-thaw stress on chimney crowns. Once the crown cracks, water seeps to the flue liner below, accelerating tile cracking and mortar deterioration. We repair crowns with HeatShield or rebuild them with proper concrete mix and overhang.
- Blocked flues from deteriorated mortar joints shedding debris. Decades of hard Nassau County groundwater weakens mortar. It crumbles. The debris falls into the flue, obstructing sweep tools and creating fire hazards. During cleaning, we remove the blockage and assess whether repointing or relining is the right next step.
- Shared-flue code violations surfacing during oil tank removal. Many Malverne homes ran fireplace and oil burner through one flue, standard practice in 1940 but prohibited now. When the oil tank gets decommissioned and gas comes in, the Nassau County Building Department requires separation. A cleaning call becomes a reline-and-separation job with permit. We handle the inspection, documentation, and coordination.

What moves the price? Flue accessibility matters. A chimney on a steep roof requires more setup time. The number of appliances served matters: a single fireplace is simpler than a fireplace-plus-boiler combination. The condition matters: light soot sweeps quickly; glazed creosote does not. We give you the full price before we start. No surprises on the bill. Call (855) 950-3861 for a free estimate - the number we quote is the number you pay.

FAQs - Chimney Cleaning & Sweep in Malverne
Yes, almost certainly. The oversized terracotta flue liner sized for your old oil burner is dangerously inadequate for modern gas exhaust, and if your fireplace and boiler share that single flue, Nassau County code requires separation. We perform a Level 2 Inspection to document the exact condition, then install our Chimney Liner & Rebuild in Malverne - typically 5-inch DuraFlex for the boiler flue - and seal or reline the fireplace flue independently. Call (855) 950-3861 to schedule - estimates are free, and we coordinate directly with the Nassau County Building Department on permitting.
If one flue tile carries exhaust from both a fireplace and any heating appliance, it’s a violation of current NYS and Nassau County code. You cannot see this from the street or the firebox. Our Level 2 camera inspection reveals the flue’s interior configuration in photographs you can see. We’ve found shared flues in homes from Hempstead Avenue to the Lakeview border, often where homeowners didn’t know their 1950s installation was ever non-compliant. The fix is straightforward once documented. Call for an inspection - we’ll show you exactly what you have.
That’s glazed creosote, and it’s caused by low-temperature gas exhaust condensing in a flue still sized for high-temperature oil combustion. The moisture mixes with residual soot, hardens into a tar-like glaze, and reduces draft efficiency. In Malverne’s climate, where winter temperatures oscillate around freezing, this condensation problem worsens. We remove glazed creosote with mechanical whipping tools and professional solvents, then assess whether your flue needs resizing or relining to prevent recurrence. The removal itself typically runs $180-$340.
Yes. Malverne’s position in the nor’easter track means your crown takes direct wind-driven rain, and Nassau County’s freeze-thaw cycle will pump water into those cracks every winter, widening them and sending water down to your liner and smoke chamber. A cracked crown that looks minor in September becomes a major water intrusion by March. We repair crowns with HeatShield cerfractory coating or rebuild with proper concrete mix and drip edge, depending on deterioration extent. Crown repair in Malverne typically runs $280-$550. Waiting costs more.
Not automatically, but practically, yes. When you decommission an oil tank and convert to gas, the utility and building inspector will require proof that your chimney meets code for the new appliance. If your chimney has a shared flue or an oversized terracotta liner - common in Malverne’s 1920s-1950s stock - the inspector will flag it. We recommend scheduling a Level 2 Inspection before your tank removal, so you know what work is needed and can coordinate timing. Call (855) 950-3861 - we’ll walk you through the sequence so you’re not caught mid-conversion with a red tag.
