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 Sands Point’s Preferred Fireplace Services Company
We’ve served local communities for over 42 years, and in that time we’ve learned that Sands Point homeowners don’t want a sales pitch. They want someone who understands that a ten-fireplace estate built in 1926 isn’t maintained the same way as a 1990s split-level in Port Washington. Our technicians are background-checked, uniformed, and trained to document every finding with photos you can see for yourself.
Our 90-Day Done Right Promise means if it’s not right, we come back. In writing, no arguing. That’s the Keystone Standard we’ve operated under since 1984. Calls are answered by a live person 24 hours a day, 7 days a week - not a voicemail queue, not an app. Most jobs are completed in a single visit, with no-hassle upfront pricing: the number on the estimate is the number on the invoice.
We know the local architecture. The Colonial Revival estates near Beacon Hill Road. The multi-flue stacks on the waterfront properties facing Hempstead Harbor. The decorative corbeled chimneys that require specialized scaffold access just to inspect properly. This isn’t generic suburban work, and we don’t treat it that way.
Our Fireplace Services in Sands Point
Gas Fireplace Service
Gas fireplaces in Sands Point often trace back to mid-century conversions, when estate owners moved away from coal or oil and installers vented new appliances into existing flues never designed for them. We see this constantly: a 1930s clay-tile flue retrofitted for a gas insert in the 1960s, the liner cracked or mis-sized, venting into a neighboring flue in a multi-fireplace stack. Our gas fireplace service includes combustion analysis, burner inspection, and a camera run to verify the flue is actually doing its job. We service units from all major manufacturers and stock common parts to avoid delays.
Wood Burning Fireplace
A wood-burning fireplace in a Sands Point estate is often the original centerpiece of the home, with a firebox built from firebrick and lime mortar that’s now approaching a century old. The salt-laden air off Long Island Sound accelerates spalling of brick faces and erosion of mortar joints, so what looks like a simple sweep often reveals deeper masonry concerns. We inspect the firebox, smoke chamber, and flue with a camera, document creosote buildup, and give you a clear picture of what’s safe to use and what needs attention before the next burning season.
Fireplace Insert
Fireplace inserts are common in Sands Point, where homeowners wanted to improve efficiency without losing the original mantel and surround. But inserts installed decades ago, especially during the oil-conversion era, frequently vent into damaged or improperly sized liners. We were at a Shingle Style estate off Middle Neck Road where the homeowner smelled smoke in an upstairs bedroom whenever the living-room fireplace ran. A camera run down the flue showed the mid-century oil-conversion era had left a cracked terra-cotta liner hidden behind a decorative chimney front. We relined the flue with a HeatShield-applied liner, reset the firebox, and showed the homeowner the footage before and after. If you’re considering a new insert, we size the liner properly and use professional-grade materials - no shortcuts that leave you with a venting problem six months later.
Damper Repair
Original throat dampers in Sands Point’s older fireplaces are often rusted, warped, or missing entirely after decades of salt-air exposure. A failed damper means heat loss up the flue, smoke spillage into the room, and in some cases, a complete inability to use the fireplace safely. We repair and replace dampers, including top-sealing damper installations that seal at the chimney crown rather than the throat, improving efficiency and keeping out the rain and wildlife that plague waterfront properties. Every repair is documented with before-and-after photos.
Firebox Repair
The firebox takes the direct heat, and in Sands Point’s century-old fireplaces, the firebrick and refractory mortar are often deteriorated to the point of exposing the surrounding structure to heat and combustion gases. We rebuild fireboxes with HeatShield refractory materials, matching the original construction where possible while meeting modern safety standards. This isn’t cosmetic work - a compromised firebox is a genuine fire hazard, and we show you exactly where the damage is before quoting any repair.
Fireplace Conversion
Converting a wood-burning fireplace to gas, or updating an older gas installation, requires more than dropping in a new appliance. In Sands Point’s multi-flue systems, we verify that the target flue is properly sized, undamaged, and not cross-connected to a neighboring fireplace. We handle the conversion from start to finish, including gas line coordination, proper venting, and final inspection. The result is a fireplace you can use with confidence, backed by our 90-Day Done Right Promise.
Trusted Brands We Service in Sands Point
We work exclusively with professional-grade materials from industry-trusted brands: HeatShield for refractory repair and liner restoration, Gelco for caps and accessories, and Copperfield for specialty chimney supplies. We stock common parts and materials locally, so most Sands Point repairs don’t wait on shipping. When a damper fails or a cap blows off in a winter storm off the Sound, we can usually get it handled quickly. No builder-grade substitutes, no guessing whether the part will fit your 1920s flue.
Common Fireplace Services Problems We See in Sands Point Homes
- Cracked terra-cotta liners hidden behind decorative fronts. The mid-century oil and gas conversions on Sands Point estates often left original clay-tile flues with new appliances venting into them. The damage sits behind ornate chimney fronts and is only found with camera evidence. A Level 1 visual sweep misses this entirely.
- Salt-air spalling and mortar erosion. The Cow Neck Peninsula’s exposure to Long Island Sound means sustained coastal winds carry salt that attacks brick faces and lime mortar joints year-round. Chimney crowns, flashing, and stack masonry fail here faster than anywhere inland in Nassau County.
- Cross-connections between flues in multi-fireplace systems. Estates with four to ten fireplaces share chimney structures, and a damaged liner or missing partition can vent one appliance into a neighboring flue. This is a carbon monoxide risk that only a Level-2 camera inspection reveals.
- Freeze-thaw damage after insufficient winter maintenance. Water enters cracked crowns and deteriorated mortar, then expands in cold snaps. Annual cleaning appointments in Sands Point should include a masonry condition check before and after each heating season.

FAQs - Fireplace Services in Sands Point
Because the original clay-tile flues in Gold Coast estates are frequently cracked or mis-sized after mid-century conversions, and the damage is hidden behind decorative chimney fronts that a visual sweep cannot see past. Salt-air masonry deterioration also progresses faster here than inland, so what looked sound last year may not be now. We document every inspection with photos and a plain-English verdict. Call (516) 927-2678 to schedule - estimates are free.
An unlined flue in a century-old Sands Point estate is not automatically unusable, but it must be evaluated with a camera to determine if the masonry is intact and properly sized for your appliance. Many unlined flues can be restored with a HeatShield applied liner, avoiding a full rebuild. We show you the footage and explain your options before any work is quoted. Call (516) 927-2678 for an inspection.
The sustained coastal winds off Long Island Sound carry salt that accelerates spalling of brick faces and erosion of lime mortar joints at a rate far more aggressive than inland Nassau County. This means chimney crowns, flashing, and exterior masonry often need attention before the flue itself shows problems. Every fireplace service visit we make in Sands Point includes an exterior masonry assessment. Call (516) 927-2678 to schedule before the next heating season.
Third-degree creosote is a hardened, tar-like deposit that forms when wood burns at low temperatures or with insufficient airflow, and it is highly combustible. In Sands Point’s older fireplaces with damaged dampers or restricted flues, incomplete combustion is common, leading to rapid creosote buildup. It cannot be removed with a standard brush and requires specialized treatment. We check for it during every sweep and show you what we find. Call (516) 927-2678 if you’ve been burning without an annual inspection.
Watch for soot buildup around the insert, moisture stains on the surrounding masonry, or any smell of combustion gases - all signs that the original flue may be cracked, mis-sized, or improperly vented. Decades-old inserts in Sands Point estates were often installed by contractors who never ran a camera to verify flue condition. We inspect the full venting path and show you what we’re seeing before recommending any work. Call (516) 927-2678 for a safety check.
