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 Old Westbury’s Preferred Fireplace Services Company
Old Westbury homeowners know their masonry. They’ve lived with these fireplaces for decades, and they can spot a salesman fast. We’re not that. Our Fireplace Services team documents every flue with a Level-2 camera inspection - photos you can see, a plain-English verdict - and nothing gets recommended without the footage to back it up.
We’ve earned a strong local reputation in Nassau County’s interior, with homeowners in Old Westbury and nearby communities returning to us for annual service year after year. Our reviews from Old Westbury customers consistently mention the same things: the technician showed up in uniform, explained what the camera found, and the price matched the estimate exactly. No arguing, no paperwork shuffle - just the 90-Day Done Right Promise in writing.
Response time to Old Westbury is typically within a few business days for standard scheduling, though we always recommend booking before September if you have multiple formal fireplaces that saw light use last winter. Our crews know the difference between a Westbury split-level with one prefab unit and an Old Westbury estate with eight original masonry stacks - and they plan the visit accordingly.
That local knowledge matters. We know the soft historic brick and natural lime mortar common to pre-WWII estates here deteriorates differently than modern materials. We know the northwest wind exposure accelerates creosote layering in flues that only see use at Christmas. And we know that a crew unprepared for multi-flue Gold Coast work will miss things - or sell things - they shouldn’t.
Our Fireplace Services in Old Westbury
Gas Fireplace Service
Many Old Westbury estates converted their formal room fireplaces to gas log sets in the 1980s and 1990s, often venting into the original unlined coal-era flue. That setup works until it doesn’t. We service the burner assembly, check gas pressure and valve function, and run a camera up the flue to confirm the venting path is intact. On a recent visit to a property off Post Road, we found a gas fireplace venting into a flue that had partially collapsed at the second floor - invisible without the camera, and dangerous to keep running. We shut it down, showed the homeowner the photo, and relined with DuraFlex the same week. Most gas fireplace services in Old Westbury run $180-$320.
Wood Burning Fireplace
The wood-burning fireplaces in Old Westbury’s older homes were built for a different fuel and a different era. Original terra-cotta flue tiles from the 1920s frequently show cracks or full separation under modern wood-burning temperatures, and the soft historic brick fireboxes erode faster than hard modern firebrick. We clean, inspect with camera, and assess whether the unit can continue as-is or needs repair. A standard sweep and Level-2 inspection for a wood-burning fireplace in Old Westbury is typically $280-$380. If we find Stage 2 or Stage 3 creosote - common in low-use formal fireplaces that never get hot enough to burn it off - the removal runs $450-$650.
Fireplace Insert
Fireplace inserts are one of our most requested services in Old Westbury, and for good reason. A properly sized insert with a stainless liner dropped down the existing flue can transform a drafty, inefficient formal fireplace into a genuine heat source. But sizing matters enormously on these old stacks. The original flue dimensions were engineered for open-hearth drafting, not insert airflow, and a unit jammed into too large a flue will soot, smell, and underperform. We measure twice, specify inserts from trusted manufacturers, and complete the liner installation with Olympia Chimney or DuraFlex components sized to the appliance. Full insert with liner installation in Old Westbury typically runs $2,800-$4,500 depending on flue height and access.
Damper Repair
Seized or rusted dampers are routine on Old Westbury estates where fireplaces sat unused for decades. A damper that won’t open fully chokes the fire and sends smoke into the room. One that won’t close bleeds heated air up the flue all winter. We free, repair, or replace dampers - including top-sealing dampers that stop drafts at the chimney crown where they’re more effective. Damper repair or replacement in Old Westbury runs $240-$480 for standard throat dampers, $520-$780 for top-sealing units with installation.
Firebox Repair
The firebox takes the direct heat, and in Old Westbury’s historic homes it’s often built of soft brick with lime mortar joints that have turned to powder. We rebuild with HeatShield refractory mortar or full firebrick replacement where the structure has compromised. Firebox repair in Old Westbury typically runs $850-$2,200 depending on whether we’re patching localized deterioration or rebuilding full walls.
Fireplace Conversion
Converting a wood-burning fireplace to gas - or vice versa - on an Old Westbury estate requires more than a new burner. The flue must be evaluated for the new fuel’s venting requirements, and multi-fireplace homes often have shared or adjacent flues that complicate the design. We handle the full scope: gas line coordination, burner specification, flue relining if needed, and permit-ready documentation. Fireplace conversions in Old Westbury run $1,800-$3,600 for gas-to-wood or wood-to-gas with basic relining.
Trusted Brands We Service in Old Westbury
We stock parts and specify materials from the brands that hold up in real chimneys: DuraFlex stainless liners for relining jobs, HeatShield refractory systems for firebox and smoke chamber restoration, Gelco caps and accessories, and Olympia Chimney components for new construction and inserts. We don’t use builder-grade substitutes - these are the materials we install in our own homes, and they’re what we carry on our trucks for Old Westbury service calls. That means faster turnaround when your formal dining room damper fails the week before Thanksgiving. No waiting on a parts order from three states away.
Common Fireplace Services Problems We See in Old Westbury Homes
- Cracked terra-cotta liners in original coal-era flues. The flue tiles installed in 1920s estate homes were never designed for modern wood-burning temperatures. We regularly find horizontal cracks, spalled surfaces, and separated joints - damage that a basic Level 1 sweep from the top down will miss entirely without a camera.
- Stage 2 and Stage 3 creosote in seldom-used formal fireplaces. Old Westbury’s cold northwest wind exposure and long heating season mean flues that never reach sustained high temperatures build glazed creosote faster than heavily used family room fireplaces. The library or parlor hearth that gets two fires a year is often the most dangerous.
- Chimney swift nesting in low-use flues. The heavy oak and beech canopy around Old Westbury estates provides ideal nesting habitat, and chimney swifts - federally protected - frequently occupy formal fireplace flues by June. Active nests cannot legally be removed, which means a fall service call becomes a November appointment. We see this pattern every year on properties with this combination of age, canopy cover, and infrequent use.
- Appliances vented into flues never designed for them. On multi-fireplace estates, the basement utility or kitchen hearth often vents into a stack that was originally built for a different appliance or no appliance at all. A sweep who assumes one flue per fireplace will miss it. We map every flue to every appliance, every time.

FAQs - Fireplace Services in Old Westbury
Yes. The unused fireplaces are often the ones with the worst creosote buildup and the most deterioration, because they never get hot enough to dry moisture or burn off residue. In Old Westbury’s climate, a formal fireplace that sees two fires a winter can accumulate dangerous glazing while sitting apparently idle. We inspect all seven, document each flue with photos, and tell you which can wait and which can’t. Call (845) 757-0998 to schedule a full-estate inspection - estimates are free.
You see the footage yourself. Our Level-2 inspection ends with photos of your flue’s interior on a tablet screen, and we explain what you’re looking at in plain English. Cracked terra-cotta, missing mortar joints, or an unlined masonry stack venting a modern gas appliance - that’s not opinion, it’s visible damage. We don’t recommend liners for flues that don’t need them, and we don’t ask you to trust a verbal report. The camera doesn’t upsell. Call (845) 757-0998 and we’ll show you your flue.
Most often it’s a combination of a cold, oversized flue and a deteriorated smoke chamber. Old Westbury’s formal room fireplaces were built for open-heath drafting with tall, wide flues that don’t establish proper draw with a small modern fire. Add a smoke chamber eroded by a century of heat and acid, and the smoke finds the path of least resistance - into your dining room. We camera-inspect to confirm, then rebuild the smoke chamber with HeatShield or specify a properly sized insert. The fix is mechanical, not mysterious. Call (845) 757-0998 for a camera inspection.
If they’re chimney swifts, no - not while the nest is active. Chimney swifts are federally protected under the Migratory Bird Treaty Act, and removing an active nest carries heavy penalties. In Old Westbury, this is a recurring issue on estate properties with heavy canopy cover and low-use formal fireplaces that provide ideal nesting habitat. By October, the swifts have usually migrated, but if they’ve nested, we must wait. The solution is prevention: a properly fitted cap installed in spring, before nesting season. Call (845) 757-0998 and we’ll inspect, identify the species, and schedule accordingly.
Yes. On multi-fireplace Old Westbury estates, we routinely service gas log sets, wood-burning hearths, and inspect dampers and caps in a single visit. We plan the day around your property’s scope - not around squeezing in another stop. Background-checked, uniformed technicians, most jobs completed in one visit, and the price is set before we start. Call (845) 757-0998 to book a full-estate service day.
On a 1920s estate off Store Hill Road we pulled three seasons of Stage 2 creosote out of the library flue, found the original terra-cotta liner cracked and separated at the third joint, then HeatShield-relined the flue and rebuilt the smoke chamber so the formal fireplace could finally draft. In the same visit we serviced the gas log set in the dining room, freed a seized damper, and capped a stack that had been funneling oak leaves and beechnut debris all fall. One day, one crew, one invoice - and the homeowner had photos of every flue before we left.
That’s how we work in Old Westbury. No flash, no shortcuts, just the thing done correctly.
