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.

Call (845) 757-0998 to schedule - a live person answers, any hour.
We’ve been dispatching to Jericho from our New York City office for decades, and we know the hamlet’s housing stock intimately: the post-WWII colonials along the Jericho Turnpike corridor, the split-levels tucked behind Old Jericho Turnpike, the raised ranches near the Long Island Expressway. These aren’t abstract categories to our technicians. They’re specific chimney types with specific failure patterns, and we treat them accordingly. When you call Hearthstone Chimney Co., you’re not getting a generic sweep crew that glances up the flue and moves on. You’re getting Chimney Cleaning & Sweep technicians who understand that a Jericho chimney from 1962 is usually a multi-flue masonry system with a gas insert that may or may not belong there.
Why Hearthstone Chimney Co. Is Jericho’s Preferred Chimney Cleaning & Sweep Company
We’ve served Nassau County communities for over 42 years, and Jericho homeowners have been part of that story since our earliest days. The referrals we get here tend to travel block by block - one neighbor tells another after we’ve documented a cracked liner with photos they could see for themselves. That’s how trust accumulates in a place like Jericho: slowly, person to person, with evidence.
Our response time to Jericho is typically same-week during spring and summer, and we add capacity each September before the October rush. We don’t promise same-day dispatch - we promise we’ll be there when we say, with background-checked, uniformed technicians who complete most jobs in a single visit. No-hassle upfront pricing means the number on your estimate is the number on your invoice.
What sets us apart in this market is our documentation. Every Level 2 inspection ends with photos you can see, a plain-English verdict, and a written report. In Jericho’s tight subdivisions where homeowners know their property lines and their codes, that transparency matters. We file permits properly with the Town of Oyster Bay. We don’t cut corners that would get noticed.
Our Chimney Cleaning & Sweep Services in Jericho
Level 1 Inspection
A Level 1 inspection is the baseline for any Jericho chimney that’s been in regular use with no changes to the system. We examine the readily accessible portions of the chimney, the firebox, and the flue opening. For a 1950s colonial off Jericho Turnpike with an original masonry fireplace that’s been swept annually, this may be sufficient. But in Jericho, we often find that the “routine” call reveals something the homeowner didn’t know: a second flue they forgot about, a gas insert that was never properly lined, or water damage from last winter’s nor’easter that spalled the crown. We always recommend what’s actually needed, not what’s easiest to sell.

Level 2 Inspection
Level 2 is where we do our real work in Jericho. This is the camera inspection - a close visual scan of the entire flue interior, the smoke chamber, and all accessible portions of the chimney structure. We recommend Level 2 for every home sale, every new homeowner, every system that’s had a fuel change or insert installation, and any chimney that’s suffered a weather event or earthquake. In Jericho, that describes most of the chimneys we see. The original clay tile flue liners in these 50-70 year old homes crack, spall, and shift. Our camera finds what a flashlight glance misses. You get photos you can see, a plain-English verdict, and a written report. If we find damage, we show you exactly where and explain what it means for safe operation. Nothing is recommended without evidence you can verify yourself.

Creosote Removal
Creosote builds in layers, and Jericho’s pattern is distinctive: chimneys that sit cold from May through September, then get fired hard when the first October cold front drops in. That stop-start cycle produces glazed creosote - the hard, tarry deposit that standard brushing won’t touch. We use professional-grade rotary systems and, when necessary, chemical treatments to break down heavy buildup. For homes burning seasoned hardwood, annual sweeping keeps creosote at manageable levels. For properties that have burned unseasoned wood or had drafting problems, we may find significant accumulation that requires more intensive cleaning. We price it upfront and explain what we found before we proceed.

Soot Removal
Soot is the lighter, powdery residue that coats flue walls, smoke chambers, and damper assemblies. In Jericho’s gas-converted fireplaces, soot combines with corrosive condensation to attack original clay liners that were never designed for cooler gas exhaust temperatures. We remove soot thoroughly, check for underlying moisture problems, and document liner condition. A clean flue is only the starting point. The real question is whether the system behind the soot is sound enough to operate safely for another season.

Annual Sweep
Jericho homes with multiple fireplaces - common in the larger colonials and custom builds added in later decades - need a systematic annual sweep that addresses every flue, not just the one in the living room. We schedule these as coordinated appointments, inspecting and cleaning each flue in sequence. The oil or gas furnace flue is often the forgotten one, and it’s frequently the most deteriorated. Our annual sweep protocol covers it all, with documentation for each system.

Fireplace Cleaning
The firebox, smoke shelf, and damper assembly collect ash, debris, and animal nesting material that a standard flue sweep doesn’t fully address. We clean these accessible areas as part of our comprehensive service, checking for cracked firebrick, deteriorated mortar, and proper damper operation. In Jericho’s older homes, we’ve found everything from collapsed smoke shelves to improperly installed gas-log sets that obstruct the flue. We fix what’s broken, document what we can’t, and never declare a system safe when it isn’t.

Common Chimney Cleaning & Sweep Problems We See in Jericho Homes
- Multi-flue colonials inspected as single-flue jobs. Many Jericho homes have two or even three flues - fireplace, furnace, and sometimes a wood stove or second fireplace. A sweep that only addresses the visible fireplace flue leaves dangerous creosote buildup and liner damage hidden in the others. We inspect and document every flue on the property.
- Gas inserts in unlined or improperly lined wood-burning fireboxes. The 2000s conversion boom dropped gas-log sets into Jericho fireplaces that still had original clay tile liners sized for wood combustion. Those liners crack from thermal shock, and the gas exhaust cools too quickly in the oversized flue, producing corrosive condensation. We see this weekly. It requires relining, not just a sweep.
- Freeze-thaw damage from Nassau County winters. Jericho’s brick chimneys absorb moisture through aging mortar joints, then the winter oscillation across freezing expands that water and spalls the brick face. Nor’easters drive rain directly into uncapped flues. By October, the damage is done and the first fire reveals the problem. We catch it in inspection before you light up.
- Unpermitted reline work in Town of Oyster Bay jurisdiction. Jericho’s governing municipality requires permits for liner replacements and significant repairs. In these tight, well-watched subdivisions, skipping the permit step risks neighbor complaints and failed future inspections. We file properly, every time. No exceptions.

FAQs - Chimney Cleaning & Sweep in Jericho
Yes, and the inspection matters more than the sweep itself. Gas burns cleaner than wood, but the original clay flue liner in your 1960s split-level was sized for wood combustion temperatures. Gas exhaust is cooler and wetter, and it condenses corrosive moisture against that oversized liner. The liner cracks. The metal insert corrodes. Carbon monoxide can leak into wall cavities. We inspect the liner condition with a camera, verify proper sizing for the gas appliance, and document what we find. If the liner is intact, a basic sweep and inspection may suffice. If it’s cracked, we discuss relining before you operate another season. Call (845) 757-0998 - estimates are free.
Your colonial likely has one flue for the fireplace and a second serving the oil or gas furnace or boiler. Both exhaust into the same chimney structure but through separate passages. Our sweep covers every flue on the property - we don’t stop at the pretty one in the living room. The furnace flue is often more deteriorated because it runs more hours per year and produces acidic condensation. We inspect and clean both, document each separately, and explain any differences in condition. A square deal means nothing hidden.
A Level 2 inspection adds a camera scan of the entire flue interior, close examination of the smoke chamber and accessible attic portions, and a written photo report. On a 50-70 year old Jericho chimney, that’s the difference between “looks fine from the bottom” and “here’s the cracked liner at course 12 that will leak combustion gases into your bedroom wall.” We recommend Level 2 for every new homeowner, every fuel change, every home sale, and any chimney that’s been unused for more than a season. The cost difference is typically $170-$290 above a Level 1, and the information it provides is the basis for every safety decision that follows.
Yes. Town of Oyster Bay requires permits for liner replacements and significant chimney repairs. We handle the filing as part of our reline service - it’s not an extra charge or a separate step for you to manage. In Jericho’s tight subdivisions where neighbors know the code enforcement officers, unpermitted work gets noticed. We’ve been called to fix other companies’ permit shortcuts. We don’t create that problem. Everything we do is documented, permitted, and inspectable.
Usually, yes - and the problem is often worse than you expect. Nassau County’s freeze-thaw cycle attacks mortar and brick whether the chimney is in use or not. Water intrusion through a missing cap or cracked crown spalls flue liners and rusts dampers. Animals nest in idle flues. The first fire in October doesn’t “warm things up gently”; it applies full combustion temperatures to a system that may have deteriorated significantly. We recommend a Level 2 inspection before that first fire, especially for chimneys idle two or more years. The inspection costs less than emergency service after a chimney fire or CO alarm. Call (845) 757-0998 to schedule before the October rush.
