We’ve been working on Hewlett chimneys since the early 1980s, back when the post-war Cape Cods along Franklin Avenue and Broadway were barely thirty years old. Those same chimneys are now seventy-plus, and the salt-laden air off Reynolds Channel and Brosewere Bay has done its slow work on the brick and mortar. We know the housing stock here: the shared flues, the oil-soot mixed with creosote, the Sandy patches that seemed fine in 2013 and are now crumbling. When you call us, you’re not getting a dispatcher in another state reading from a script. You’re getting our Chimney Cleaning & Sweep team - local technicians who understand why a Hewlett chimney fails differently than one in Garden City or Mineola.

Why Hearthstone Chimney Co. of New York City Is Hewlett’s Preferred Chimney Cleaning & Sweep Company

Frank Calucci founded this company in 1984, and we’ve spent over 42 years building a reputation in Nassau County by doing the thing right and standing behind it. In Hewlett specifically, that means understanding the dual-fuel chimneys that dominate the 11557 ZIP - structures built for wood-burning fireplaces above and oil-burning furnaces below, sharing the same clay flue tiles. Most competitors treat a cleaning as a brush-and-vacuum operation. We treat it as a diagnostic opportunity, because in this town, the cleaning often reveals what the homeowner cannot see.

Our Level 2 inspections end with photos you can see and a plain-English verdict. No engineering jargon, no scare tactics. If the flue tile is cracked, we show you the crack. If the crown patch from 2012 is failing, we document the deterioration. Our 90-Day Done Right Promise covers every job in writing - if it’s not right, we come back, no paperwork and no arguing. That’s the Keystone Standard: Krafted right, Every time, Your home first, Standing behind it.

A live person answers our phones 24 hours a day, 7 days a week. Not voicemail. Not a callback queue. And our background-checked, uniformed technicians arrive with upfront pricing - the number on the estimate is the number on the invoice. Most jobs finish in a single visit, because we know Hewlett homeowners have better things to do than wait around for a second appointment.

Our Chimney Cleaning & Sweep Services in Hewlett

Level 1 Inspection

Our Level 1 inspection covers all readily accessible portions of your chimney structure and flue, appropriate for annual maintenance on systems with no known changes. In Hewlett’s 1940s-1960s housing stock, we use this baseline check to monitor the gradual deterioration that salt air and freeze-thaw cycling accelerate on windward chimney faces. We document mortar joint condition, crown integrity, and visible flue tile surfaces. If your chimney has not been inspected since before Hurricane Sandy, we may recommend upgrading to Level 2.

Level 2 Inspection

This is where we do our most important work in Hewlett. A Level 2 inspection includes internal camera scanning of the entire flue, attic and basement visual checks, and inspection of all accessible interior chimney portions. Given the shared oil-wood flues common here, this is the only way to catch the lateral cracks and deteriorated mortar joints that allow carbon monoxide migration between floors. On a recent Level 2 inspection in the Franklin Avenue neighborhood, we found that a post-Sandy patch on the chimney crown had concealed a deep lateral crack in the clay flue tile, allowing carbon monoxide from a downstairs oil furnace to seep into the attic. We cleaned out a heavy deposit of hybrid oil-soot and creosote, then recommended a HeatShield liner repair to restore safety. Every Hewlett homeowner with a pre-1970 masonry chimney and dual-fuel use should consider this inspection essential, not optional.

Creosote Removal

Creosote buildup in Hewlett chimneys is not standard wood-fire creosote. The shared flue configuration means sulfurous oil soot mixes with wood creosote, creating a hybrid deposit that is chemically more aggressive toward clay flue tiles than either fuel produces alone. We remove this corrosive layer using professional-grade rotary systems and hand tools sized to your flue diameter, then evaluate the tile surface beneath for the accelerated deterioration this combination causes. Annual removal is critical for safety and for preserving the remaining life of your original liner.

Soot Removal

Oil soot accumulation in the lower flue sections of Hewlett’s shared chimneys restricts draft and increases the risk of backdrafting into living spaces. Our soot removal service uses high-efficiency HEPA containment to protect your home interior, with particular attention to the smoke chamber and damper assembly where oil soot tends to compact. We finish with a draft test to confirm proper flue function before we leave.

Annual Sweep

For Hewlett homeowners, we recommend annual sweeping for any chimney serving a wood-burning fireplace, and annual inspection with conditional sweeping for oil-wood shared flues. The 11557 climate - wet nor’easters off the Atlantic, freeze-thaw winters, salt air penetration - means your chimney works harder and degrades faster than inland systems. Our annual service includes full debris removal, firebox and damper cleaning, and a written condition report with photos. Schedule before the heating season; our calendar fills by October.

Fireplace Cleaning

Fireplace cleaning in Hewlett addresses the aesthetic and functional buildup that affects hearth performance: ash compaction, smoke staining, deteriorated firebrick, and damper corrosion from salt air exposure. We clean the firebox, smoke shelf, and visible flue throat, with recommendations for firebrick repair or damper replacement as needed.

Trusted Brands We Service in Hewlett

We work exclusively with professional-grade materials from brands that meet our standard for durability in coastal conditions. For liner repairs and restorations in Hewlett’s corrosive dual-fuel environment, we specify HeatShield cerfractory resurfacing systems and DuraFlex stainless relining products where factory relining is indicated. For crown and flashing repairs on chimneys already weakened by salt air and freeze-thaw damage, we use Gelco and Copperfield components rated for marine-zone exposure. We stock common parts for fast turnaround on Hewlett jobs, because a chimney out of service in January is not a situation anyone wants to prolong.

Common Chimney Cleaning & Sweep Problems We See in Hewlett Homes

• Corrosive hybrid soot destroying clay tile joints. The shared oil-wood flues in Hewlett’s post-war housing deposit sulfurous oil soot mixed with wood creosote, a combination that chemically attacks clay flue tile joints faster than single-fuel use. We find deteriorated joints in chimneys less than fifteen years old that should have decades of service remaining.
• Post-Sandy crown patches failing and hiding structural cracks. After Hurricane Sandy’s 2012 wind and flooding damage, many Hewlett chimneys received rapid crown and flashing repairs. More than a decade later, those patches are cracking and separating, concealing deeper lateral cracks in the masonry and flue tiles beneath. Only a thorough cleaning and Level 2 camera inspection reveals the full extent.
• Freeze-thaw spalling on windward chimney faces. Atlantic nor’easters drive sustained moisture into porous aging mortar on south and west-facing chimney walls. Winter freeze-thaw cycling then accelerates spalling and joint failure at rates we do not see in inland Nassau County communities like Garden City or Mineola.
• Carbon monoxide migration from cracked shared flues. A single cracked tile or failed mortar joint in a dual-fuel chimney simultaneously creates fire hazards from wood-fire use and carbon monoxide risks from oil-burner exhaust. The danger is hidden, silent, and more common in Hewlett’s aging shared-flue housing stock than most homeowners realize.
