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.

AfterFast, Reliable Chimney Cleaning & Sweep Across Larchmont
A professional chimney cleaning and sweep in Larchmont typically runs $189-$349 for a standard Level 1 service with full debris removal, while a Level 2 camera inspection runs $289-$479 depending on flue accessibility and the number of appliances served. Most appointments are completed in a single visit, and our crews are scheduled from our New York City office with dedicated routing into Larchmont, Mamaroneck, and the Sound shore.
We’ve been answering calls with a live person for over 42 years, and we’ve learned what Larchmont chimneys actually need. The village’s concentration of pre-WWII masonry homes - especially in Larchmont Manor along the water - means we see a pattern of deterioration that inland Westchester crews simply don’t encounter: salt-laden coastal air attacking Sound-facing mortar joints, original terracotta liners that have never been updated, and single-wythe brick chimneys pressed into service for appliances they were never designed to vent. Our Chimney Cleaning & Sweep team documents everything with photos you can see and a plain-English verdict. No recommendation without evidence. Call (516) 927-2678 to schedule - estimates are free.
Why Hearthstone Chimney Co. Is Larchmont’s Preferred Chimney Cleaning & Sweep Company
Larchmont homeowners tend to stay put. They’ve owned their houses for twenty, thirty, forty years. They’ve also been burned by a contractor who talked fast, billed faster, and left behind work that didn’t hold up. We understand that. Our reputation here was built slowly - one chimney at a time, one neighbor telling another that we showed the photos, explained the problem, and charged what we quoted.
Our technicians are background-checked, uniformed, and trained to complete most jobs in a single visit. No-hassle upfront pricing means the number on your estimate is the number on your invoice. And our 90-Day Done Right Promise is in writing with no arguing - if it’s not right, we come back. We’ve stood behind that for over 42 years, and we plan to be answering the phone in Larchmont for decades more.

Our Chimney Cleaning & Sweep Services in Larchmont
Level 1 Inspection
A Level 1 inspection is the baseline service every Larchmont homeowner should schedule annually - a visual examination of readily accessible portions of the chimney exterior, interior, and connecting appliance. For the standard 1910-1950 masonry homes that dominate Larchmont’s housing stock, this catches obvious creosote buildup, blockages from nesting material, and deteriorated firebox conditions. The service typically runs $189-$249. We remove all soot and first-degree creosote and leave the flue clear for safe operation.
Level 2 Inspection
This is where we do our most important work in Larchmont. A Level 2 inspection includes everything in Level 1, plus a camera scan of the full flue interior and examination of attics, crawl spaces, and basements as needed. In Larchmont Manor and the village’s other historic neighborhoods, this is essential. Original 1920s-1940s terracotta liners crack. Single-wythe brick chimneys develop hidden spalling. And salt air corrosion on Sound-facing sides progresses out of sight from the ground.
On a 1928 Tudor Revival in Larchmont Manor, our tech camera-scoped a terracotta flue serving a fireplace the owners had used for years and found cracked liner sections and a collapsing smoke chamber crown. The Sound-facing mortar joints had eroded two to three times deeper than the sheltered side. We laid out the footage on a tablet, removed first-degree creosote, installed a HeatShield liner, and replaced the chimney cap with a Gelco model. Nothing was recommended without the homeowner seeing the evidence first. Level 2 service in Larchmont runs $289-$479.
Creosote Removal
Creosote buildup is the leading cause of chimney fires nationwide, and Larchmont’s older fireplaces - many with shallow fireboxes and restricted flue sizing - tend to accumulate it faster than modern units. We distinguish between first-degree creosote (sooty, easily brushed), second-degree (tar-like flakes requiring rotary tools), and third-degree (glazed, hardened deposits that need chemical treatment or mechanical removal). Third-degree creosote removal in Larchmont typically runs $349-$549 depending on severity and flue length. We use professional-grade equipment and, when needed, Copperfield and Olympia Chimney products to restore proper flue function.
Soot Removal & Fireplace Cleaning
A thorough fireplace cleaning goes beyond the flue. We clean the firebox, smoke shelf, damper assembly, and accessible exterior masonry. In Larchmont’s coastal environment, this matters more than inland homeowners might expect. Salt air corrodes steel dampers and chase covers; combined with soot accumulation, this can cause dampers to seize or leak. Our fireplace cleaning service, typically $229-$329, includes inspection of these components and documentation of any corrosion we find. If your damper is rusted through, we’ll show you the photo and explain your options - repair with Famco components or replacement - before any work proceeds.
Annual Sweep
For Larchmont homeowners who burn regularly, an annual sweep is non-negotiable for safety and for homeowner’s insurance compliance. We schedule these proactively each fall before burning season begins. The service includes full debris removal, a basic condition assessment, and a written report suitable for insurance documentation. Annual sweep agreements are available at a preferred rate - call (516) 927-2678 for details.

Trusted Brands We Service in Larchmont
We don’t use builder-grade substitutes. For Larchmont’s demanding coastal environment, we specify professional-grade materials from Gelco, Olympia Chimney, Famco, and Copperfield - brands engineered to withstand corrosive salt air and temperature cycling. We stock common caps, dampers, and flashing components for faster turnaround on Larchmont jobs, and we source HeatShield refractory mortar and DuraFlex liner systems for relining projects that require factory-certified materials. Every product carries a manufacturer’s warranty in addition to our 90-Day Done Right Promise.
Common Chimney Cleaning & Sweep Problems We See in Larchmont Homes
- Salt-spray asymmetry on Sound-facing chimneys. In Larchmont Manor, the chimneys facing Long Island Sound suffer mortar joint erosion two to three times faster than sheltered sides. This isn’t visible from the street. A close cap and crown inspection - standard in our Level 2 service - catches it before water intrusion spalls brick faces and compromises structural integrity.
- Original terracotta liners cracked by age and thermal shock. The village’s 1920s-1940s chimneys were built with clay tile liners that have now seen a century of heating cycles. Cracked sections allow flue gases to contact surrounding masonry, accelerating deterioration and creating carbon monoxide intrusion risk. A camera inspection reveals what a standard sweep cannot.
- Modern appliances vented into chimneys never designed for them. Many Larchmont homeowners have added high-efficiency furnaces or water heaters that vent into original single-wythe brick flues. These appliances produce cooler, wetter exhaust that condenses on flue walls and destroys liners from the inside. Draft problems and backdrafting are common symptoms we diagnose during Level 2 inspection.
- Deteriorated chimney crowns and rusted metal components. The combination of freeze-thaw cycling and elevated humidity from salt air destroys concrete crowns and corrodes steel chase covers, dampers, and flashing faster than in inland Westchester. We document crown condition and metal integrity on every Larchmont inspection.

FAQs - Chimney Cleaning & Sweep in Larchmont
A standard sweep is sufficient if your chimney is relatively new, undamaged, and burning the same fuel it was designed for. In Larchmont, most chimneys are none of these things. The village’s original 1920s-1940s terracotta liners have aged past their design life, and salt air corrosion on Sound-facing masonry creates hidden damage that a ground-level visual inspection misses. We recommend a Level 2 camera inspection for any Larchmont home with a chimney over 50 years old, any change in appliance or fuel type, or any suspected damage. The camera footage shows you exactly what we see - no recommendation without evidence. Call (516) 927-2678 to schedule; estimates are free.
Salt-laden coastal air accelerates mortar joint erosion and metal corrosion far faster than the same freeze-thaw stress would cause inland. In Larchmont Manor specifically, we’ve documented Sound-facing mortar joints eroding two to three times deeper than sheltered sides - an asymmetry invisible from the street but obvious on close inspection. This spalls brick faces, compromises crown integrity, and rusts dampers and chase covers prematurely. A thorough exterior inspection, standard in our Level 2 service, catches this pattern before structural damage requires rebuild rather than repair.
We look for camera-documented evidence of cracked, shifted, or missing terracotta liner sections; gaps between liner tiles allowing flue gas contact with surrounding masonry; or deterioration sufficient to compromise draft and safety. We also evaluate whether the chimney is being asked to vent an appliance it was never designed for - a common situation in Larchmont’s 1910-1950 housing stock. No liner is recommended without footage you can review yourself, a plain-English explanation of the hazard, and a written estimate with no pressure to decide immediately. Some conditions can be monitored; others require prompt action. We’ll tell you which is which.
Yes - though perhaps not for the reason you expect. Even infrequent use produces some creosote, and in Larchmont’s coastal climate, an unused chimney faces separate risks: moisture intrusion from deteriorated crowns, animal nesting in uncapped flues, and salt-air corrosion of metal components. An annual inspection catches these problems before they become expensive repairs. For very light burners, we may recommend inspection every two years with sweep as needed, but we make that determination based on what we find - not a blanket schedule. Call (516) 927-2678 and we’ll advise based on your specific chimney and usage.
First-degree creosote is light, sooty, and brushes away easily with standard sweep tools - what we remove in a routine annual service. Third-degree creosote has hardened into a glazed, tar-like or shiny black deposit that adheres to flue walls and requires rotary mechanical removal, chemical treatment, or both. It forms when combustion is incomplete, often due to burning unseasoned wood, restricted air supply, or oversized fireboxes - all common in Larchmont’s older fireplaces. Third-degree creosote is the most combustible form and the leading fuel for chimney fires. We assess creosote type during every inspection and document severity with camera footage so you understand what you’re dealing with.
