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.

We’ve been working Mamaroneck chimneys for over 42 years, and the pattern we see here is unlike anywhere else in Westchester. This village sits directly on Long Island Sound, and that salt-laden coastal air changes everything about how a chimney ages, what fails first, and how often you need a sweep with a mirror on the back side of your stack, not just a brush down the flue. The north- and east-facing sides of chimney stacks near Mamaroneck Harbor and the west-facing slopes toward the Sound spall years ahead of the sheltered sides - a directional weathering signature from prevailing nor’easter winds that rarely shows up this dramatically even in neighboring Rye or Larchmont.
Why Hearthstone Chimney Co. Is Mamaroneck’s Preferred Chimney Cleaning & Sweep Company
Homeowners in the Village and Town of Mamaroneck know the difference between a sweep who brushes and leaves, and one who documents what they find. We photograph every inspection. You get a plain-English verdict, not a jargon report designed to sell you something. Our 90-Day Done Right Promise is backed in writing - if it’s not right, we make it right, no paperwork and no arguing.
Our technicians are background-checked, uniformed, and carry professional-grade materials from HeatShield, Gelco, and Olympia Chimney on every truck. That means most Mamaroneck jobs finish in one visit. No callbacks for parts. No waiting on a supplier in White Plains.
Calls reach a live person, 24/7. Not a voicemail. Not a callback queue. Not an app. When you’re staring at a drafty fireplace on a February night in Mamaroneck, that matters.
We’ve earned our reputation on the 1920s-1940s housing stock that dominates here - Tudor Revival, Colonial Revival, and Cape Cod homes with original full-height masonry chimneys built before clay flue liner standards were common. We know what to look for before the brush touches the flue.
Our Chimney Cleaning & Sweep Services in Mamaroneck
Level 1 Inspection
Our Level 1 inspection covers all readily accessible portions of your chimney - firebox, damper, smoke chamber, and flue interior - with visual examination from the roof and hearth. In Mamaroneck, we treat this as the baseline for inland homes above Boston Post Road, where salt exposure is reduced but pre-WWII construction still demands careful attention to original clay liners and aging mortar. A Level 1 in Mamaroneck typically runs $189-$249.
Level 2 Inspection
This is where our Chimney Cleaning & Sweep in Mamaroneck work separates from generic sweeps. A Level 2 includes video camera scanning of the entire flue interior, plus accessible portions of the attic, basement, and exterior stack. On waterfront streets and west-facing slopes, we’re specifically hunting the salt-driven mortar deterioration and spalling that stays invisible from the roof ridge. The camera finds cracks in original clay liners before brushing turns them into expensive problems. Level 2 inspections in Mamaroneck range $289-$449, and we include photos you can see with a plain-English verdict.
Creosote Removal
First-degree creosote - flaky, sooty, brushable - is what most Mamaroneck homeowners expect. Third-degree creosote is a different animal: glossy, tar-like, and bonded to the flue wall. It forms when wood burns too cool or green wood is used, and it’s the fuel behind most chimney fires. On Long Island Sound, third-degree buildup is compounded by damp firewood stored in humid coastal air. We remove both with rotary chains for glazed deposits and professional brushes for standard buildup. First-degree removal runs $189-$269; third-degree or heavy glazed deposits requiring rotary treatment range $329-$449.
Soot Removal & Annual Sweep
The annual sweep is structural maintenance in Mamaroneck, not a luxury. Between salt spray, freeze-thaw cycling, and the higher humidity off the Sound, your chimney works harder here than in inland Westchester. Our annual service includes complete soot and debris removal, firebox cleaning, and a written condition report. We recommend annual service for all Mamaroneck chimneys, and twice-yearly for waterfront properties with active fireplaces. Annual sweeps run $189-$249; properties requiring more frequent service receive bundled pricing.

Trusted Brands We Service in Mamaroneck
We stock professional-grade materials from HeatShield, Gelco, and Olympia Chimney on every Mamaroneck truck. HeatShield for flue liner resurfacing when original clay is cracked but structurally sound. Gelco stainless caps and dampers that outlast galvanised hardware three to one in salt air. Olympia Chimney liners when relining is the right call. No builder-grade substitutes. No waiting on a parts run to Yonkers. When we find corrosion on your galvanised damper during a sweep, we can swap stainless the same day - done right, and we stand behind it.
Common Chimney Cleaning & Sweep Problems We See in Mamaroneck Homes
- Salt-driven mortar joint erosion on north- and east-facing stack faces. On waterfront blocks near Mamaroneck Harbor, the prevailing nor’easter pattern spalls brick and opens mortar joints years before the sheltered sides show damage. A sweep who only looks down the flue from the roof ridge misses it entirely. Our mirror-and-light inspection of the back side catches it early.
- Galvanised dampers, caps, and flashing corroding through while inland hardware survives. We’ve replaced galvanised dampers in Mamaroneck that failed in eight years, while identical units in Tuckahoe or Pelham are still serviceable at fifteen. The stainless upgrade costs more once. Paying twice for galvanised costs more in the end.
- Original clay flue liners cracked during routine cleaning by sweeps who didn’t inspect first. Pre-WWII Mamaroneck chimneys were built before liner standards. A first-degree creosote job becomes a HeatShield install when the brush hits a liner that was already fractured. We camera-inspect before we brush. Every time.
- Freeze-thaw damage to chimney crowns accelerated by salt-weakened mortar. Water driven into crown seams by winter nor’easters expands with each freeze cycle. Annual cleaning and inspection catches crown cracks before they channel water into the stack body and require rebuild rather than repair.

On a 1930s Tudor Revival off Taylors Lane near Mamaroneck Harbor, we pulled first-degree creosote from a firebox that hadn’t been swept in three seasons, then found the original clay flue liner cracked and the galvanised damper rusted solid from salt air. We swapped the damper for a stainless unit, applied HeatShield to the flue, and set a new stainless chimney cap over a crown we rebuilt where freeze-thaw had opened the mortar. The homeowner told us the neighbor’s inland plumber had walked right past the same cracking two years earlier.

FAQs - Chimney Cleaning & Sweep in Mamaroneck
Waterfront chimneys in Mamaroneck should be inspected annually at minimum, and swept twice yearly if the fireplace sees regular winter use. Inland homes above Boston Post Road, with reduced salt exposure and more shelter from prevailing winds, can typically maintain annual sweep and inspection intervals without issue. The difference is the rate of metal corrosion and mortar spall, not superstition. Call (914) 246-5794 to schedule - estimates are free.
Salt-laden air from Long Island Sound accelerates galvanised steel corrosion by a factor of two or more compared to inland Westchester. Your cousin’s damper in Tarrytown faces the same rain but not the same salt spray. We replace failed galvanised dampers with stainless units from Gelco that are rated for coastal exposure. The upgrade pays for itself the first time you don’t replace the same component twice.
Not without a Level 2 camera inspection first. Original clay liners in pre-WWII Mamaroneck housing stock are often fractured, and routine brushing can worsen cracks that were already present. We camera the flue, show you the photos, and give you a plain-English verdict. If the liner is sound, we sweep. If it’s cracked, we discuss HeatShield resurfacing or Olympia Chimney relining before any brush touches the flue. Nothing is recommended without camera evidence you can see for yourself.
First-degree creosote is dry, flaky, and brushes away easily. Third-degree is glossy, tar-like, and bonded to the flue wall - it’s concentrated fuel for chimney fires. Mamaroneck’s coastal humidity means firewood often carries more moisture, and cooler flue temperatures from damp fuel promote third-degree buildup. We remove first-degree with standard brushes and third-degree with rotary chains. The inspection tells us which we’re dealing with before we quote.
Yes. We install and service HeatShield flue resurfacing systems and Olympia Chimney stainless liners, and we carry both on our Mamaroneck trucks. DuraFlex is also in our inventory for specific relining applications. All materials are professional-grade, no builder-grade substitutes, and all relining work carries the 90-Day Done Right Promise in writing. Call (914) 246-5794 for an exact quote on your specific flue condition.
