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.

We’ve been working on Bethpage chimneys for over 42 years. We know the post-war Cape Cods along Stewart Avenue, the ranch houses off Hempstead Turnpike, and the rural-edge properties near the Levittown border where wood stoves still shoulder the heating load. That local knowledge matters because Bethpage’s chimneys fail in specific ways that generic sweeps miss.
Why Hearthstone Chimney Co. Is Bethpage’s Preferred Chimney Liner & Rebuild Company
Bethpage homeowners call us back. They mention our technicians by name to neighbors. Our reputation here was built one chimney at a time - documented inspections, plain-English verdicts, and no arguing if something needs correction.
Our reviews from Bethpage customers consistently note the same things: the photos they can see for themselves, the written 90-Day Done Right Promise with no paperwork games, and the live person who actually answers the phone at 10 PM on a Saturday. We’re not the cheapest outfit advertising in central Nassau County, and we don’t try to be.
Response time to Bethpage is typically next-day or within 48 hours once materials are confirmed in stock. For liner replacements, we pre-stage DuraFlex or Olympia Chimney components so the crew isn’t waiting on freight. Rural-edge properties outside Bethpage proper sometimes add 15-20 minutes to the drive, but we schedule accordingly and don’t charge travel fees within our service area.
What separates us from chains and one-truck operators is simple: we document, we explain, and we stand behind it in writing. Russell Haines has run Hearthstone Chimney Co. since 1984 with the same standard - Krafted right, Every time, Your home first, Standing behind it.
Our Chimney Liner & Rebuild Services in Bethpage
Stainless Steel Liner Installation
Stainless steel liners are our most common recommendation for Bethpage’s converted oil-to-gas homes. The original clay flue tiles in your 1950s Cape Cod or ranch were sized for an oil furnace’s higher exhaust temperature and volume. When natural gas replaced oil - often in the 1970s or 1980s - the flue became oversized, causing chronic underdrafting and acidic condensate that erodes mortar from the inside. A correctly sized 316Ti stainless steel liner from DuraFlex or Olympia Chimney restores proper draft, contains condensate, and carries a lifetime warranty when professionally installed. We wrap and insulate per manufacturer spec, install a new top plate and cap, and leave you with photos of the completed flue.

Flexible Liner Solutions
Not every Bethpage chimney is straight. The offset flues in some 1960s ranches, or chimneys with minor settling, require a flexible liner that navigates bends without breaking the draft path. We use professional-grade flexible products from trusted manufacturers, never builder-grade substitutes. The installation still ends with a Level 2 camera inspection and photo report you can see.

Liner Replacement
Full liner replacement becomes necessary when clay tiles are cracked, shifted, or the flue is actively spalling from condensate damage. In Bethpage, we regularly find this condition hidden behind what looks like a sound chimney from the roofline. Our process: camera inspection first, photos you can see, then a plain-English verdict on whether replacement can wait or needs immediate action. No recommendation without evidence. If replacement is indicated, we remove the compromised tiles, install the new liner system, and rebuild the smoke chamber and firebox as needed. Most liner replacements in Bethpage run $2,800-$4,500 depending on flue height and diameter.

Partial Chimney Rebuild
Central Nassau County’s freeze-thaw cycles are hard on 60-75 year old mortar joints. After a harsh winter, we get calls from Bethpage homeowners whose brick faces are spalling or whose mortar is crumbling to sand. A partial rebuild addresses the damaged section - often the top several courses, the crown, and sometimes the firebox - without tearing down the entire structure. We match existing brick where possible and use professional-grade crown repair materials from HeatShield or Copperfield. Partial rebuilds in Bethpage typically start at $3,200 and range to $6,500 depending on how far the deterioration extends. We’ll tell you honestly if the damage is cosmetic and can wait, or if it’s structural and needs immediate attention.

Trusted Brands We Service in Bethpage
We don’t guess on materials. Hearthstone Chimney Co. works exclusively with professional-grade brands: DuraFlex and Olympia Chimney for stainless and flexible liners, HeatShield for crown and smoke chamber repair, Gelco for caps and top-mounted dampers, Famco for termination fittings, and Copperfield for specialty rebuild components. We stock common liner diameters and cap sizes for Bethpage’s typical flue configurations, which means faster turnaround and no waiting on backordered parts. When we specify a material, it’s because we’ve installed it, watched it perform through Nassau County winters, and trust it to outlast the job.
Common Chimney Liner & Rebuild Problems We See in Bethpage Homes
- The hidden condensate problem. Bethpage’s signature failure mode: a post-war Cape Cod converted from oil to gas decades ago, with an oversized original flue that looks fine from the roofline but is silently eroding from acidic condensate inside. We find this weekly on Stewart Avenue and throughout the 1950s developments.
- Freeze-thaw mortar destruction. Central Nassau County’s repeated freeze-thaw cycles open mortar joints and spall brick faces on 60-plus-year-old chimneys. After a hard winter, what was a hairline crack becomes a structural gap that lets water into the flue system.
- Rural-edge creosote overload. Properties on Bethpage’s outskirts burning wood as primary heat load creosote far faster than suburban occasional-use fireplaces. Third-degree glazed creosote can build in a single season, and the safe sweeping interval drops from annual to semi-annual or quarterly depending on burn practices.
- Smoke chamber and firebox deterioration. The original parged smoke chambers in Bethpage’s builder-era chimneys were never designed for decades of use. We regularly find sanded-out mortar, exposed brick, and gaps that allow heat transfer to surrounding framing - a condition that camera inspection reveals and that partial rebuild corrects.

FAQs - Chimney Liner & Rebuild in Bethpage
Yes. The original oil-era flue tiles in your Cape Cod are almost certainly oversized for your gas appliance, causing chronic underdrafting and acidic condensate that erodes mortar from the inside while the exterior looks unchanged. We were called out to a 1950s Cape on Stewart Avenue for what the owner thought was a routine cleaning; a Level 2 inspection revealed the original oil-era clay tiles were badly oversized for the home’s modern gas insert, and the flue liner was coated in acidic condensate with eroded mortar joints behind it. We wrapped and installed a correctly sized stainless steel liner with a new top plate and cap, restored the firebox and damper, and left the homeowner with a burn-practice card to cut the condensate cycle. The fireplace drafted correctly for the first time in years - no more smoke rollback on cold starts. Call (845) 757-0998 for a camera inspection and a free estimate.
Semi-annually at minimum, and quarterly if you’re burning unseasoned hardwood or running the stove continuously through winter. Rural-edge Bethpage properties with wood as primary heat load creosote faster than suburban occasional-use fireplaces. Third-degree glazed creosote can form in a single season and requires mechanical removal - not just brushing. We’ll assess your burn practices, fuel moisture, and stove model to recommend a safe interval. Call (845) 757-0998 to schedule.
It depends on where the damage is and how deep it goes. Surface mortar deterioration often indicates a partial rebuild of the affected courses plus crown repair. If the flue itself is compromised by condensate erosion, you’ll need both reline and masonry restoration. We don’t guess - our Level 2 camera inspection shows you exactly what we’re seeing, and we explain whether work is urgent or can be scheduled. Call (845) 757-0998 for a documented inspection.
Those symptoms together point to creosote buildup and possible smoke chamber deterioration. The tar smell is volatile compounds off-gassing from creosote deposits, often worse in humid weather. A sticking damper suggests corrosion, creosote glazing, or mortar debris in the throat. In Bethpage’s older chimneys, we often find both conditions plus an undersized or damaged smoke chamber behind the damper. Camera inspection confirms the extent; cleaning and partial rebuild correct it. Call (845) 757-0998 - estimates are free.
Yes. We work the rural-edge properties near the Levittown border and beyond.
