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 Hearthstone Chimney Co. Is Armonk’s Preferred Fireplace Services Company
Armonk homeowners call us because we’ve earned a reputation for plain talk and documented work. Our Level 2 camera inspections end with photos you can see on our monitor and a plain-English verdict - no sales script, no pressure. We’ve built that reputation across northern Westchester, from homes off Maple Avenue to properties along Route 22 and the winding roads near Whippoorwill Country Club.
Our dispatch is coordinated from our New York City office, but our crews serve Armonk locally every day. That means we understand the town’s specific conditions: the colder temperatures and heavier snowfall that extend burning season into April, the exposed ridgelines that create downdraft problems, and the large wooded lots where homeowners burn oak they’ve cleared themselves. We’re familiar with the 1960s-1980s executive colonials and contemporaries that dominate Armonk’s housing stock - many with two or three fireplaces that have been in continuous use for decades.
Background-checked, uniformed technicians arrive with the parts and materials to finish most jobs in one visit. Our no-hassle upfront pricing means the number on your estimate matches the number on your invoice. And every job is backed by our 90-Day Done Right Promise: in writing, no arguing. If it’s not right, we make it right.
Our Fireplace Services in Armonk
Wood Burning Fireplace Service
Armonk’s wood-burning fireplaces need more than a brush and a vacuum. The town’s heavily forested, rolling terrain creates localized downdraft conditions on exposed lots, especially along ridgelines near the Connecticut border. Incomplete combustion from poor draft produces aggressive stage-2 and stage-3 creosote deposits that a standard sweep won’t fully clear. Many Armonk homeowners burn oak and hardwood cleared from their own multi-acre properties - wood that’s often under-seasoned or mixed with green cuttings, accelerating creosote formation dramatically. We clean the firebox, smoke chamber, and flue; inspect the damper and firebrick; and run a camera to verify the flue’s condition before we declare the system safe for another season. A typical wood-burning fireplace service in Armonk runs $225-$340.

Gas Fireplace Service
Gas fireplaces in Armonk’s older homes present a specific problem: many were retrofitted into chimneys originally built for wood, with venting configurations that don’t meet current standards. Others vent into flues shared with furnaces or boilers - a setup that was common in 1970s construction but creates dangerous cross-contamination risks if the flue liner is compromised. We inspect the gas valve, pilot assembly, thermocouple, and burner; check for proper draft and clearances; and verify that the venting configuration matches the appliance’s rating plate. If your gas fireplace vents into an original clay-tile flue, we’ll camera-inspect that flue. No exceptions. Gas fireplace service in Armonk typically costs $180-$280.

Fireplace Insert Installation & Service
Fireplace inserts are popular in Armonk’s large 1960s-1980s homes, where homeowners want to improve efficiency without losing the hearth’s presence. But inserts in aging chimneys require careful evaluation. The original flue liner must handle the insert’s exhaust temperature and volume; many clay-tile liners in Armonk homes have cracked or shifted after 40-50 years of thermal cycling. We measure the firebox, verify clearances to combustibles, and camera-inspect the full flue before recommending any insert. Our installations use professional-grade components from Olympia Chimney and Famco. A full insert installation with necessary flue modifications in Armonk runs $2,800-$4,500; insert service on an existing unit is $200-$295.

Damper Repair & Firebox Repair
Dampers in Armonk’s older fireplaces often seize from rust, creosote buildup, or decades of disuse. A stuck damper wastes energy and can force smoke into your living space. Firebox brick and mortar deteriorate from repeated thermal shock, especially where water infiltration has accelerated spalling. We rebuild fireboxes with proper refractory materials rated for fireplace temperatures - not standard brick or quick-setting patch products. Firebox repair in Armonk typically runs $650-$1,400 depending on the extent of rebuild. Damper repair or replacement is $225-$450. We always photograph the damage before quoting, and we show you the photos.

Trusted Brands We Service in Armonk
We stock parts and materials from professional-grade brands that hold up in Armonk’s demanding conditions: HeatShield for flue resurfacing, Gelco for chimney caps and accessories, Olympia Chimney for liner systems, and Famco for termination fittings. These aren’t builder-grade substitutes. When we install a chimney cap on an Armonk home exposed to northern Westchester’s wind and snow load, we use a product rated for it. That means faster turnaround for repairs - no waiting two weeks for a special order - and work that lasts.
Common Fireplace Services Problems We See in Armonk Homes
- Cracked clay-tile flue liners hidden below the roofline. In Armonk’s IBM-era executive homes, original clay-tile liners have endured 40-50 years of thermal cycling. The damage is often isolated to one or two courses and invisible from the top or bottom without a camera. We won’t recommend a full relining until we’ve shown you the footage.
- Downdraft from ridgeline exposure. Homes on Armonk’s higher, wooded lots - especially near the Connecticut border - experience wind-induced downdraft that pushes smoke back into the room. This is a draft problem, not a dirty chimney problem, and it requires diagnosis of the chimney height, surrounding terrain, and cap configuration, not just another sweep.
- Appliances vented into unlined or undersized flues. Many Armonk homes have furnaces or boilers vented into chimney stacks never designed for them, often through a second or third flue that hasn’t been inspected in years. A routine Level 1 cleaning of the fireplace flue misses this entirely.
- Heavy creosote from under-seasoned property wood. Burning oak cleared from your own wooded lot is economical, but green or partially seasoned wood produces stage-2 and stage-3 creosote that standard brushes won’t remove. Annual professional cleaning isn’t a suggestion here - it’s necessary for safety.

FAQs - Fireplace Services in Armonk
Both flues need inspection. In Armonk’s multi-fireplace executive homes from this era, the second flue often vents a furnace or boiler into a stack never designed for it, and it typically hasn’t been inspected in years. We camera-inspect every flue that serves a fuel-burning appliance. Call (914) 409-9387 to schedule - estimates are free.

Property-cleared oak in Armonk is frequently under-seasoned or mixed with green wood, which produces aggressive stage-2 and stage-3 creosote deposits that standard brushes won’t fully remove. The town’s extended burning season - colder temperatures keep fireplaces active into April - adds more thermal cycles per year than chimneys in milder areas. Annual professional cleaning removes these deposits before they become a chimney fire hazard. Call (914) 409-9387 to book before the next burning season.

A Level 2 inspection uses a video camera to examine the full interior of the flue, revealing cracked or offset clay tiles, deteriorated mortar joints, and creosote glazing hidden below the roofline - damage invisible from either end of the chimney. In Armonk’s 1960s-1980s homes with original liners, this footage often shows isolated damage that HeatShield resurfacing can repair, avoiding an unnecessary full relining. You watch the footage on our monitor before we quote any work. Call (914) 409-9387 to schedule.

It’s a draft problem. Armonk’s rolling, heavily forested terrain - especially on exposed ridgelines near the Connecticut border - creates localized downdraft conditions that push smoke back into the room. Cleaning won’t fix this. We diagnose chimney height, surrounding topography, and cap configuration to identify the source, then recommend the right correction. Call (914) 409-9387 and we’ll sort it out.

Not all clay-tile liners need full replacement. In Armonk’s IBM-era homes, we’ve found that damage is often isolated to one or two tile courses, and HeatShield resurfacing restores the flue to safe condition at a fraction of relining cost. We make that determination only after a Level 2 camera inspection - never from a roofline glance. If the footage shows widespread failure, we’ll explain why and show you the evidence. Call (914) 409-9387 for a free estimate.
