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 Bethpage’s Preferred Fireplace Services Company
We’ve served Nassau County communities for over 42 years, and Old Bethpage’s particular mix of mid-century housing and coastal exposure is familiar territory. Our technicians know the difference between a chimney that needs a sweep and one that needs a liner - and we won’t confuse the two to pad a bill.
Our Old Bethpage customers get the same standard we apply everywhere: Level-2 camera inspections with photos you can see, a plain-English verdict, and no-hassle upfront pricing. The number on the estimate is the number on the invoice. Most jobs finish in a single visit, and every repair carries our 90-Day Done Right Promise in writing - if it’s not right, we come back, no arguing, no paperwork chase.
Calls reach a live person 24 hours a day, 7 days a week. Not a callback queue. Not an app. A real voice, because when you smell smoke where you shouldn’t, or your damper won’t open on the first cold night, you don’t want to leave a message.
Our Fireplace Services in Old Bethpage
Gas Fireplace Service
Gas fireplace service in Old Bethpage typically costs $180-$320 and includes burner inspection, gas-line leak test, thermocouple check, and glass cleaning. But the real work often starts above the roofline. Many Old Bethpage gas fireplaces were retrofitted into chimneys that still run original clay liners oversized for the appliance - killing draft and risking carbon monoxide spillback into the room. We size the flue to the appliance, not the other way around. If your gas insert was tied into an old oil flue without relining, we’ll find it and tell you exactly what it takes to make it safe.
Wood Burning Fireplace
Wood burning fireplace repair and restoration in Old Bethpage runs $250-$650 for typical firebox and damper work, with full rebuilds reaching $1,500-$3,500 depending on extent. The humid Nassau coastal climate accelerates mortar joint erosion in these single-wythe chimneys, and Long Island’s freeze-thaw cycles crack crowns that were never designed for 50+ years of weather. We inspect with a camera before quoting - you’ll see what we see - and we use professional-grade materials from HeatShield and Olympia Chimney for repairs that hold up to salt air.
Fireplace Insert
Fireplace insert installation in Old Bethpage ranges $1,200-$2,800 for the unit and labor, with liner adaptation adding $800-$1,600 when the existing flue doesn’t match. This is where Old Bethpage’s oil-to-gas conversion history matters most. An insert rated for a 6-inch flue tied into a 9-inch clay liner from 1968 won’t draft properly - it may not draft at all. We measure, we document, and we install the right DuraFlex liner to match. No guesswork. No “it should be fine.”
Damper Repair
Damper repair in Old Bethpage typically runs $180-$340 for plate replacement or track realignment, with full top-sealing damper installations at $450-$650. Salt air corrodes steel damper plates and frames faster here than inland, and water intrusion from failed caps or crowns rusts the assembly from above. If your damper won’t open fully or seals poorly, you’re losing heat up the flue and inviting downdrafts. We fix the damper and trace the water source so it doesn’t happen again next season.
Firebox Repair
Firebox repair in Old Bethpage costs $350-$850 for refractory panel replacement or tuckpointing, with full firebox rebuilds at $1,200-$2,400. The combination of acidic oil-combustion residue and decades of thermal cycling has degraded many original fireboxes in 1960s-era Old Bethpage homes. We use HeatShield refractory products rated for the temperatures these units see, and we document the repair with photos for your records.
Fireplace Conversion
Fireplace conversion - wood to gas, or oil to gas appliance tie-in - runs $1,500-$4,500 in Old Bethpage depending on liner requirements and gas-line extension. The critical step is flue sizing. We inspect with a camera before any conversion quote, because an oversized clay liner from the oil era is not a safe exhaust path for a modern high-efficiency gas unit. We’ll show you the measurement, explain the code, and install a proper DuraFlex or Olympia Chimney liner sized to the appliance.
Trusted Brands We Service in Old Bethpage
We stock parts and materials from DuraFlex, HeatShield, Gelco, and Olympia Chimney - professional-grade brands, no builder-grade substitutes. For Old Bethpage’s salt-air environment, that means stainless steel caps and copper flashing as the default, not galvanized components that pit through in a decade. We keep common sizes on our trucks to complete most repairs in one visit, and what we don’t carry we source fast. Your fireplace doesn’t stay cold because we’re waiting on a part.
Common Fireplace Services Problems We See in Old Bethpage Homes
- Galvanized caps and flashing corroded through from salt air. Within 10-15 years, galvanized steel pits and fails in Nassau’s coastal climate, letting water track down the flue to rust dampers and degrade fireboxes. We replace with stainless DuraFlex caps and copper flashing as standard.
- Original clay flue liners spalled and oversized for modern gas appliances. Decades of oil combustion etched the interior surface, and the 9-inch liner engineered for a 150,000 BTU oil boiler is dangerously oversized for a 35,000 BTU gas insert. Draft collapses. Carbon monoxide risk rises. We measure, document, and install properly sized liners.
- Mortar crowns cracked from freeze-thaw cycles. Nassau County’s wet winters and hard freezes open cracks that funnel water into the chimney structure. We rebuild with proper slope and overhang, sealed with professional-grade crown coat.
- Blocked or deteriorated flues discovered on the first cold night. Long Island nor’easters drive sustained cold that pushes homeowners to light fireplaces they haven’t touched since March - and that’s when they find the bird nest, the spalled liner, or the damper frozen shut. We inspect before burning season, camera and all.

The Old Bethpage Difference: What Actually Fails Here
Old Bethpage developed almost entirely as a post-WWII suburban hamlet in the 1960s-70s, meaning the vast majority of its homes have original masonry chimneys with clay tile flue liners that are now 50-60+ years old and were engineered to serve oil-fired boilers - not the gas or heat-pump systems most homeowners have since switched to. That oil-to-gas conversion wave left behind oversized, acid-etched clay liners that are both undersized for modern appliance exhaust and structurally compromised, making full liner inspection and relining the defining chimney job in this market - not simple creosote sweeping.
On a 1968 split-level off Haypath Road in Old Bethpage, our tech found the original galvanized chimney cap pitted through from salt air, rust streaks bleeding down the brick above the firebox; the damper had seized and a Level 2 inspection showed the clay flue liner spalled and oversized for the newer gas insert. We replaced the cap with a stainless DuraFlex model, rebuilt the crown, re-flashed in copper, and installed a properly sized liner - restoring safe draft and passing the buyer’s inspection.
When Old Bethpage homeowners converted from oil heat to gas in the 1990s-2010s, many contractors tied the new gas appliance into the original oversized oil flue without relining - a code-compliance and safety problem chimney techs routinely uncover here, especially during the real estate inspection surge that accompanies home sales in the Town of Oyster Bay. If you’re buying or selling in 11804, expect this to come up. We document what we find, explain it plainly, and fix it if you want the job done.

FAQs - Fireplace Services in Old Bethpage
The smell usually comes from a deteriorated clay liner or a blocked flue, not surface creosote. In Old Bethpage’s oil-conversion chimneys, the liner interior is often etched and porous, trapping combustion byproducts that bleed odor into the house even when the flue looks “clean.” A Level 2 camera inspection finds the source - call (934) 348-4832 for a free estimate.
Yes, almost certainly. The original liner was sized for oil combustion and is now oversized for your gas appliance, which destroys draft and can allow carbon monoxide to spill into living space. We measure the flue and appliance output, then install a properly sized liner if the mismatch is confirmed - estimates are free.
Every 12 months, without exception. Nassau’s salt air and freeze-thaw cycles accelerate cap, crown, and mortar damage compared to drier inland areas, and the oil-conversion legacy adds liner deterioration to the checklist. Annual Level 2 inspection with camera documentation catches what a visual sweep misses.
The galvanized cap and crown go first - typically within 10-15 years in this salt-air environment. Once the cap fails, water tracks down the flue and attacks the damper and firebox from above. Stainless caps and properly sloped crown rebuilds are the preventive fix we recommend as standard here.
You need an inspection immediately, and likely a liner. An oversized oil flue paired with a modern gas appliance is a known carbon monoxide risk and typically violates current code. We see this exact scenario routinely in Old Bethpage’s 1960s-70s housing stock. We’ll camera the flue, measure the mismatch, and quote the proper liner installation - call (934) 348-4832 for a free estimate.
