We’ve been driving to Woodbury from our New York City base for over 42 years, and we know the difference between a Syosset split-level and a Woodbury colonial on Sylvan Lane or Woodbury Road. The tall masonry chimneys here, often three or four stories above grade, take a beating from Long Island’s freeze-thaw cycles that shorter chimneys in flatter neighborhoods simply don’t face. When a crown spalls or a liner cracks on one of these, water finds its way in fast. We’re familiar with the local building department’s expectations for permit documentation on rebuilds, and we photograph every stage so there’s no question about what was done and why.
Why Hearthstone Chimney Co. of New York City Is Woodbury’s Preferred Chimney Liner & Rebuild Company
Woodbury 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 and a plain-English verdict - no jargon, no scare tactics. We’ve completed liner replacements and rebuilds on homes from Sylvan Lane to the Woodbury Heights section, and our technicians are background-checked, uniformed, and trained to complete most jobs in a single visit.
Our response time to Woodbury is typically same-day or next-day for standard calls, and we answer emergency calls with a live person 24/7 - not a voicemail, not a callback queue. The 90-Day Done Right Promise governs every job: if it’s not right, we come back, in writing, no arguing. That’s the Keystone Standard, and it’s how we’ve operated since Frank Calucci founded this company in 1984.
We understand Woodbury’s housing market. Homes here routinely transact above $1 million, and pre-sale Level II chimney inspections have become standard. A documented inspection from Hearthstone, with photos and a clear verdict, protects both seller and buyer. We’ve seen too many Woodbury deals delayed because an unqualified sweep missed cracked terra cotta or spalled crown brick that a proper camera inspection would have caught.
Our Chimney Liner & Rebuild Services in Woodbury
Stainless Steel Liner Installation
Stainless steel relining is our most common Woodbury job, and for good reason. The original terra cotta flue liners in 1970s and 1980s Woodbury homes are at or past their service life, and stainless steel is the permanent fix. We install DuraFlex flexible liners for straight or offset flues, and rigid stainless for straight vertical runs where clearance allows. A typical stainless reline on a Woodbury colonial with one fireplace runs $2,800-$4,200, including the insulated top plate and connection to your appliance. For homes with two or three fireplaces, which is common north of Woodbury Road, we price each flue separately and complete the work in one day when possible.
Flexible Liner Solutions
Not every Woodbury chimney is straight. The custom homes built here in the 1970s and 1980s sometimes have offset flues or chimney shoulders that make rigid liner installation impossible. For these, we use DuraFlex flexible liners that navigate offsets while maintaining proper draft. Flexible liners are particularly useful in Woodbury’s larger homes where the chimney may serve a basement fireplace, a first-floor hearth, and an upstairs bedroom unit - each with different flue paths. Installation runs $3,200-$5,000 depending on length and offset complexity.
Liner Replacement & Repair
Sometimes the liner isn’t fully failed - it’s cracked in sections, or the mortar joints between terra cotta sections have opened. In these cases, we evaluate whether a full replacement is necessary or if HeatShield cerfractory flue sealant can restore a sound surface. HeatShield works well for minor cracking and joint gaps in otherwise sound terra cotta, and costs $1,800-$2,800 versus $3,000+ for full replacement. We never recommend HeatShield for a flue with structural spalling or displaced sections; that’s a reline job, and we’ll tell you so directly. Our Chimney Liner & Rebuild team has the camera evidence to back up either call.
Partial & Full Chimney Rebuild
When the crown is spalled, the brick faces are popping, and water has compromised the wythes between flues, a liner alone won’t solve the problem. Partial rebuilds address the crown, top courses, and damaged wythes while preserving sound lower structure. Full rebuilds are rare but necessary when the chimney leans, the footing has failed, or freeze-thaw damage extends below the roofline. Partial rebuilds in Woodbury run $4,500-$7,500; full rebuilds on tall multi-flue chimneys can reach $12,000-$18,000. We document every stage with photos, pull permits as required, and stand behind the work with our 90-Day Done Right Promise.

Trusted Brands We Service in Woodbury
We don’t use builder-grade substitutes. Our trucks carry DuraFlex stainless liners, HeatShield cerfractory sealant, and Copperfield chimney caps and flashing components - the same materials specified by factory-built fireplace manufacturers and recommended by the Chimney Safety Institute of America. For Woodbury jobs requiring custom fabrication, we source from Famco and Olympia Chimney, with most parts available within 24 hours. That means no waiting two weeks for a specialty top plate while your closing date approaches. The brands matter because a liner system is only as good as its weakest component, and we’ve seen too many failed relines caused by inferior flex pipe or uninsulated caps that condense and corrode.
Common Chimney Liner & Rebuild Problems We See in Woodbury Homes
- Cracked terra cotta in multi-flue chimneys. Woodbury’s 1970s-80s custom homes often feature two to four fireplaces sharing a common chimney mass. The original terra cotta liner sections in these multi-flue chimneys crack and separate with age, causing smoke spillage into adjacent flues - a serious health hazard we catch with our Level-2 camera inspection.
- Spalled crowns and deteriorated mortar from freeze-thaw cycles. Long Island’s humid winters deliver repeated freeze-thaw cycles that are particularly destructive to the exposed brick crowns on Woodbury’s tall, multi-story chimneys. Water infiltrates through hairline cracks, freezes, expands, and pops the brick face - accelerating damage that a crown coat or rebuild can stop.
- Gas-to-wood reconversion complications. A significant share of Woodbury’s 1970s-80s homes had wood-burning fireplaces converted to gas inserts during the 1990s and 2000s. When the home sells and the new buyer wants to restore wood-burning use, the flue typically needs a full inspection and often a stainless reline. These reconversions are a recurring local job type that techs in nearby all-rental or newer-build markets almost never see.
- Third-degree creosote in restored fireplaces. Consistent winter use of wood-burning fireplaces - more common in Woodbury’s large homes than in more modestly heated properties - means creosote at the third-degree stage is a realistic find, especially in fireplaces that went unused for years before a luxury resale. A stainless liner with proper insulation maintains flue temperature and reduces creosote accumulation going forward.
Pricing for Chimney Liner & Rebuild in Woodbury, NY
Here’s what chimney liner and rebuild work costs in Woodbury’s market. These are upfront, no-surprise ranges based on jobs we’ve completed in ZIP 11797:
| Service | Typical Range in Woodbury |
|---|---|
| HeatShield flue sealant (minor cracks) | $1,800 - $2,800 |
| Single-flue stainless steel liner (DuraFlex) | $2,800 - $4,200 |
| Multi-flue stainless reline (2+ fireplaces) | $4,500 - $7,500 |
| Partial chimney rebuild (crown, top courses) | $4,500 - $7,500 |
| Full chimney rebuild (tall multi-flue) | $12,000 - $18,000 |
| Level-2 camera inspection with photos | $289 - $389 |
What moves the number? Height of the chimney, accessibility of the flue, whether we need to remove an existing gas insert, and the condition of the crown and exterior brick. Homes over 3,500 square feet - typical in Woodbury - often have taller chimneys and multiple flues, which adds material and labor. We provide no-hassle upfront pricing: the number on the estimate is the number on the invoice. Our $89 Seasonal Tune-Up includes a basic visual inspection; if we find issues, we’ll show you the camera footage and explain your options before any additional work. Call (855) 950-3861 for a free estimate.

FAQs - Chimney Liner & Rebuild in Woodbury
You can convert back, but it’s rarely “easy” - the flue needs a full Level-2 inspection, the insert must be properly removed and capped, and the original terra cotta liner almost always needs replacement with stainless steel. On a 1978 colonial on Sylvan Lane, the homeowner wanted to convert back from a gas insert to wood-burning. Our crew removed the insert, inspected the original 8×8 terra cotta flue, and found spalled sections from past freeze-thaw cycles. We installed a 7-inch DuraFlex stainless steel liner with an insulated top plate, restoring full wood-burning function and meeting Level II inspection standards for a pending sale over $1.2 million. Call (855) 950-3861 for an inspection - estimates are free.
Spalling on the crown alone usually calls for a partial rebuild, not a full chimney reconstruction. We remove the damaged crown, rebuild with proper concrete or precast cap, and install a drip edge to direct water away from the brick faces. If the spalling has extended below the roofline or the wythes between flues are compromised, then full rebuild territory begins. Our camera inspection shows exactly how far the damage goes. Most Woodbury crown repairs run $2,200-$4,500; we’ll tell you honestly which side of that range you’re on.
A stainless steel reline on a Woodbury home over 3,500 square feet typically runs $3,800-$6,500. These homes usually have taller chimneys, multiple flues, and sometimes offset flues requiring flexible liner. The square footage itself doesn’t drive cost - chimney height, flue count, and configuration do. A 4,000-square-foot colonial with three fireplaces and a straight 35-foot flue may cost less than a 3,500-square-foot home with two offset flues at 45 feet. We measure and camera-inspect before pricing; call (855) 950-3861 for your exact quote.
The unused chimney needs inspection too - water infiltration through a cracked liner can damage the chimney structure even without combustion gases. However, an unused flue in good condition may not need immediate relining. We evaluate both chimneys with our Level-2 camera, document what we find, and prioritize based on safety and your plans. If you’re selling, buyers and their insurers often require both chimneys to pass inspection regardless of current use. The inspection cost is the same; the repair scope depends on what the camera reveals.
In Woodbury’s 1970s-1980s housing stock, we perform roughly three liner replacements for every full rebuild. Most chimneys here have sound structural brick below the roofline; the crown, cap, and liner take the worst of the weather. Full rebuilds become necessary when freeze-thaw damage extends deep, when the chimney leans, or when previous improper repairs have accelerated deterioration. An honest inspection tells the difference, and we’ll show you the photos so you can see what we see. Call (855) 950-3861 to schedule - a live person answers 24/7.
