Our technicians carry professional-grade equipment for every job, from basic soot removal to full Level 2 camera inspections.
We’ve been driving to Jericho for over 42 years - since 1984 - and we know the roads well: the split-levels clustered near Jericho Turnpike, the raised ranches off Cantiague Rock Road, the Colonials lining the streets of the Strathmore neighborhood. These aren’t abstract addresses to us. They’re the homes where original masonry chimneys built during the 1950s and 1960s Long Island boom now demand careful, knowledgeable attention.

Why Hearthstone Chimney Co. of New York City Is Jericho’s Preferred Chimney Cleaning & Sweep Company
Jericho homeowners don’t hire strangers. They hire people who show up when promised, explain what they found, and leave the job site cleaner than they found it. Our reputation in Jericho has been built one appointment at a time - neighbors telling neighbors, the way trust spreads in a community where people stay put for decades.
Our reviews from Jericho customers consistently mention the same things: the technician arrived in a marked truck and uniform, the photos from the inspection were clear, and the estimate matched the final bill. No arguing, no paperwork games. The 90-Day Done Right Promise covers every job in writing - if it’s not right, we come back. Period.
Response time to Jericho is typically same-week for standard cleaning, and we keep routes efficient by grouping appointments in Nassau County. If you’re in ZIP 11753 or 11853, you’re on our regular rotation. We also understand the local housing stock in a way that matters: Jericho’s post-WWII split-levels, raised ranches, and Colonials often contain two separate flue systems - one originally for oil heat, one for the fireplace - and our Chimney Cleaning & Sweep team inspects both, every time.
Our Chimney Cleaning & Sweep Services in Jericho
Level 1 Inspection
A Level 1 inspection is the standard annual check for chimneys with no changes in use or fuel type. In Jericho, we perform these on active fireplace flues and on gas-venting systems that remain in service. The technician examines accessible portions of the chimney exterior, interior, and connecting appliances, checking for obstructions, creosote buildup, and structural soundness. For Jericho’s mid-century homes, this baseline inspection often reveals early mortar joint deterioration from coastal salt exposure - caught early, it’s a minor repair; missed, it becomes a rebuild.
Level 2 Inspection
Level 2 inspections are where our work in Jericho diverges from standard practice. Required by NFPA 211 whenever a fuel type changes, a home sells, or damage is suspected, this inspection uses a specialized camera to examine the entire flue interior. In Jericho, the oil-to-gas conversion history makes this essential. Thousands of homes here switched fuels without relining the original oversized oil flue to the correct diameter for gas equipment. Our camera reveals what the eye cannot: cracked clay liners, moisture damage, and dangerous draft failures hiding behind brick that looks sound from the outside.
On a recent sweep in Jericho’s Strathmore neighborhood, we diagnosed a 1960s split-level where the original oil flue had been abandoned after a gas conversion - our Level 2 inspection revealed a cracked clay liner and heavy efflorescence from years of trapped condensation, requiring a HeatShield liner repair before we could safely clean the active fireplace flue. The homeowner had no idea. That’s why we document every inspection with photos and a plain-English verdict.
Creosote Removal
Creosote is the combustible residue of wood smoke, and it accumulates in every fireplace flue. Jericho’s homeowners who burn seasoned hardwood - oak and maple are common here - typically need annual creosote removal to maintain safe operation. Stage 1 creosote brushes off easily; Stage 3, glazed and hardened, requires rotary equipment and chemical treatment. We carry both. For Jericho’s seasonal residents who close up homes for winter travel, creosote left sitting through humid summers can harden aggressively - another reason we recommend annual service before the heating season begins.
Soot Removal
Soot removal addresses the fine carbon residue that coats flue walls, smoke chambers, and fireplace faces. In Jericho’s gas-converted homes, soot accumulation in the active fireplace flue often signals incomplete combustion or a drafting problem - sometimes caused by the oversized abandoned oil flue creating pressure imbalances. Our technicians don’t just vacuum soot; we determine why it’s there. We use professional-grade HEPA containment to protect your home’s interior, and we finish with a condition report that tells you what we found and what it means.
Annual Sweep & Fireplace Cleaning
Annual sweeping is the foundation of chimney safety, and in Jericho it’s particularly critical given the age of the housing stock. Our annual service includes full cleaning of the firebox, smoke chamber, and flue, plus a Level 1 inspection. For homes with two flues, we price the second flue at a reduced rate when both are serviced together. We schedule these appointments from late summer through fall to beat the rush, and we send reminder calls to our Jericho regulars so nothing gets forgotten.

Trusted Brands We Service in Jericho
We stock parts and materials from the brands that professional sweeps actually trust - no builder-grade substitutes that fail in two seasons. For liner repairs and relining work in Jericho’s converted chimneys, we use HeatShield cerfractory sealant and DuraFlex stainless steel liners, sized precisely to the appliance they serve. For caps, crowns, and exterior repairs exposed to Long Island’s coastal air, we specify Copperfield and Gelco components that withstand salt degradation. These materials live in our trucks, which means most Jericho jobs finish in a single visit. No ordering delays, no return trips, no waiting.
Common Chimney Cleaning & Sweep Problems We See in Jericho Homes
- Abandoned oil flues silently deteriorating. Homeowners assume a retired oil flue needs no maintenance, yet it silently spalls and leaks moisture into the adjacent living space. We find cracked liners and efflorescence in these “inactive” flues during routine cleaning calls - the damage has been progressing for years while the owner focused only on the active fireplace.
- Freeze-thaw and salt damage to exterior masonry. Jericho sits roughly 10-12 miles from Long Island Sound and 20 miles from the Atlantic, so prevailing winds carry measurable salt content that gradually degrades mortar joints and chimney crowns. Combined with Long Island’s repeated freeze-thaw cycles each winter - temperatures crossing 32°F dozens of times per season - the aging brick chimneys of Jericho’s mid-century housing stock experience accelerated spalling and joint erosion that neighbors in more inland areas do not see at the same rate.
- Multiple flues serviced separately, creating missed hazards. Many Jericho homes have two flues: one for the former oil boiler, one for the fireplace. When different contractors handle heating and fireplace service, neither inspects the complete system. We examine both flues every time, because a breach in one can affect draft and safety in the other.
- Gas-conversion draft failures from oversized flues. Nassau County’s near-universal shift from oil to natural gas left Jericho chimneys built for oil equipment now venting gas appliances. The mismatch produces chronic condensation, accelerated liner deterioration, and dangerous draft failures that demand professional assessment at every cleaning visit.

FAQs - Chimney Cleaning & Sweep in Jericho
Yes - the abandoned flue still requires inspection, and often repair. Jericho’s oil-to-gas conversions left thousands of chimneys with oversized flues that trap condensation and develop cracked liners while homeowners assume they’re “retired.” We recommend a Level 2 inspection for any converted system to assess hidden moisture damage before it affects your home’s structure or the active flue. Call (855) 950-3861 for a free estimate.
Efflorescence is mineral salt deposited by moisture migrating through masonry - it signals water intrusion, not surface dirt. In Jericho, this pattern is common on abandoned oil flues where gas-conversion condensation has accumulated for years, and on exterior crowns exposed to salt-laden coastal air. The staining is a symptom; the cause is a liner or crown breach that needs professional diagnosis. We document the source with camera inspection and explain the repair path in plain English.
Active wood-burning fireplaces need annual cleaning; gas vents and inactive flues need annual inspection at minimum. Jericho’s freeze-thaw climate and aging masonry make yearly professional assessment particularly important - small cracks become major breaches faster here than in milder inland zones. We send reminder calls to our Jericho customers each August so you can book before the fall rush.
Sometimes - if the draft issue is caused by creosote buildup, soot obstruction, or a blocked cap. Often in Jericho, though, draft problems trace to the oil-to-gas flue mismatch: an oversized flue creates sluggish draft that pulls combustion gases back into the living space. Cleaning alone won’t fix this. Our technician will diagnose the root cause during inspection and explain whether cleaning, relining, or repair is the right path. Estimates are free.
A Level 2 inspection is a camera examination of the entire flue interior, required when fuel type changes, a home sells, or damage is suspected. In Jericho, we strongly recommend it for any home with an oil-to-gas conversion history, because the original flue was sized for oil equipment and is now mismatched to gas appliances. The camera reveals cracked liners, moisture damage, and draft failures that a standard visual inspection cannot see. Every Level 2 ends with photos you can review and a written verdict - documented like an engineer, explained like a craftsman.
