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.

Why Level Two Chimney White Plains Is Mamaroneck’s Preferred Chimney Cleaning & Sweep Company

Since 2009, Level Two Chimney has documented more than 38,000 chimney inspections and cleanings, and the Mamaroneck calls follow a pattern we know cold. Homeowners near the Sound read about carbon monoxide risk or hear about a chimney fire in the neighborhood, then they want to know if their flue is actually safe. We answer that question with a camera. Not a flashlight glance from the firebox. A real NFPA 211 Level 2 scan with footage you watch alongside the tech, and a photo record you keep.
Our Chimney Cleaning & Sweep teams come uniformed and background-checked. License information is printed on every page we hand you, and the tech’s name is on the booking. Corrine Halstead oversees operations, and she’s built the company around a simple rule: no recommendation without an image the homeowner can point to. If we tell you a liner needs replacing, you’ll see the crack on camera before you sign anything.
We’re independently owned and operated under the Haven Standard, and that standard has teeth. Clause 4 requires a documented photo record on every job, and we’ve run that archive continuously since 2009. Mamaroneck homeowners in areas like Heathcote Hill and Washingtonville tell us the same thing: the camera changed the conversation. No more taking a contractor’s word on a liner condition. The picture either shows damage or it doesn’t.
Before

Level 2 Inspection
For most Mamaroneck homes, especially those built between 1915 and 1950, we recommend a Level 2 inspection at least every other year, and every year if the chimney is used for heat. This is the full camera scan required under NFPA 211, covering the flue liner, smoke chamber, damper, crown, and exterior masonry. On Mamaroneck’s Sound-facing blocks, we pay particular attention to the south and southwest faces where salt-laden wind does the most damage.

Creosote Removal
Mamaroneck’s humidity means wood fires produce more first-degree creosote than dry-air inland towns, and if that builds into shiny, hard second- or third-degree creosote, it’s a fuel source waiting for a spark. Our techs identify the creosote class with a camera before and after removal, so you know exactly what came out. We use mechanical rotary cleaning on hardened deposits, not just brushes that smear the surface.

Soot Removal
Gas and oil appliances vent through the same stack in many older Mamaroneck homes, and they produce a fine, acidic soot that clings to flue walls. That soot traps moisture from the Sound’s always-humid air and accelerates liner corrosion. We clean it, show you the before-and-after footage, and note any pitting that suggests the liner is approaching replacement age.

Annual Sweep
Homes that burn wood one or more times a week through the Long Island winter should get a sweep every year, full stop. The freeze-thaw cycle here cracks crowns early, and loose mortar falling into the flue gets caught in creosote deposits. An annual sweep keeps the flue clean enough to actually see what the liner looks like. That’s the real point: a clean chimney is an inspectable chimney.

Trusted Brands We Service in Mamaroneck

When a Mamaroneck chimney needs new components, we use materials sourced through Haven’s buying network from manufacturers like DuraFlex, Olympia Chimney, and Copperfield. DuraFlex liners are our standard for relining work because they hold up to the coastal humidity and acidic flue gases we see on the Sound. If your chimney has an Olympia cap or a Copperfield damper, we service those directly and can quote replacements on the spot. No waiting on a supplier from out of state.
Common Chimney Cleaning & Sweep Problems We See in Mamaroneck Homes
- Salt-eaten mortar on windward faces. Chimneys facing south and southwest absorb decades of salt-laden nor’easter rain, and the mortar washes out years before the same failure appears inland in Harrison or Scarsdale.
- Cracked 1920s clay liners. Most original clay tile flue liners from the 1920s and 1930s have vertical cracks by now. The question isn’t whether they’re cracked. It’s whether the gaps are big enough to let heat reach the framing.
- Converted oil furnaces vented into brick chimneys not built for gas. Gas exhaust is cooler and wetter than oil smoke, and it condenses inside old masonry, turning mortar to powder. The liner condition is what determines safety, not the age of the furnace.
- Third-degree creosote gloss. The combination of humid Sound air and irregular burning produces hard, shiny creosote that brushes won’t remove. Homeowners who only burn on weekends are more likely to find this because fires never get hot enough to burn deposits off.
Pricing for Chimney Cleaning & Sweep in Mamaroneck, NY

Our written sweep pricing for Mamaroneck homes runs $189 to $329 for a standard cleaning with Level 1 inspection and photo documentation. A Level 2 camera inspection added to a sweep brings the visit to $249 to $399 depending on chimney height and flue count. Creosote removal in third-degree condition starts at $349 and goes up from there because it requires rotary equipment and takes longer. Relining work runs $2,900 to $6,500 depending on liner diameter and length, and we quote that in writing with the camera images that justify it.
Every quote is line-item, signed, and handed to you before work starts. If a competitor’s written estimate is lower for the same scope, bring it in. The Free Second Opinion applies, no charge. Call (914) 350-5204 and a live person answers, day or night.

A Coastal Chimney Problem You Won’t See Inland
Mamaroneck sits directly on Long Island Sound, and that changes how chimneys age. Salt air is relentless on the south- and southwest-facing faces, the ones that catch prevailing wind. Mortar joints erode like soft sandstone, and brick faces spall, flake, and crumble decades earlier than the same construction just a few miles north in Scarsdale or Harrison. From the street, a Mamaroneck chimney can look straight and solid. Up close, the windward face tells a different story.
The dense concentration of 1920s to 1940s Tudor and Colonial homes built along the New Haven Line commuter corridor means a large share of Mamaroneck’s housing stock carries original clay flue liners now a hundred years old. Those liners were never designed for modern gas furnaces or weekly wood fires, and most have never been relined. Combine hundred-year-old clay with salt-eaten mortar and a crown that’s been through ninety winters of freeze-thaw, and you’ve got a chimney system that needs annual inspection, not a five-year check-in.
On a 1927 Tudor near Orienta Point, our crew found exactly this. The south-facing crown was heavily spalled, and the clay flue liner had cracked in three separate sections after decades of salt-laden nor’easter rain. We swept out first-degree creosote, ran the Level 2 camera down the flue while the homeowner watched in real time, and documented the liner damage with stills before recommending a DuraFlex reline. The homeowner saw the cracks with their own eyes before any price was discussed. That’s the way it should work.

FAQs - Chimney Cleaning & Sweep in Mamaroneck

Salt air and wind-driven rain from Long Island Sound erode mortar and brick on exposed faces faster than the inland climate in White Plains, so chimneys in Mamaroneck show spalling and crown cracking at younger ages. We recommend annual Level 2 camera inspections for Sound-facing homes, even if the fireplace gets light use. Call (914) 350-5204 for a written quote and camera record; the inspection is part of every visit.
An annual sweep is necessary but not sufficient on a 1930s clay liner, because sweeping removes creosote but doesn’t reveal cracks that let heat reach combustible framing. A Level 2 camera scan is the only way to see liner condition, and on a ninety-year-old clay system we recommend it at least once a year. We won’t sell a reline without camera evidence you watch yourself. Call (914) 350-5204 to book a sweep plus inspection at one written price.
That white crust is mineral salt left behind when saltwater from Sound winds soaks into the masonry and evaporates, leaving salt crystals that pop the mortar and brick surface; the crumbling is spalling. It’s the signature Mamaroneck coastal failure pattern, and it means the brick and mortar on that face need repair before interior flue damage follows. We document it with photos and give you a written crown and repointing quote before any work starts. Call (914) 350-5204 for an exterior assessment.
Third-degree creosote, the hard shiny glaze that forms in humid Mamaroneck fires, can usually be removed with rotary mechanical cleaning rather than a reline, but the liner underneath must then be camera-inspected for cracks. A reline is only justified if the camera shows the liner is structurally compromised; a glaze removal alone won’t fix a cracked clay liner. The footage makes the call. Call (914) 350-5204 and we’ll show you the before and after.
Yes, because in most older Mamaroneck homes the chimney also vents a gas or oil appliance like a furnace or water heater, and a damaged liner can leak carbon monoxide even if the fireplace is decorative. The camera scan reveals the flue condition independent of firebox use. If the liner is intact, you leave with photo proof and no upsell. Call (914) 350-5204 and schedule the one hour it takes to know for sure.
