Gary Murphy, our owner and lead technician, handles every job personally. Call (844) 660-6590 for a free estimate and same-week scheduling.

Our Chimney Liner & Rebuild Services in Van Nest
Stainless Steel Liner Installation
For most Van Nest homes, a stainless steel liner is the definitive fix for coal-era flue mismatch. We install 6-inch DuraFlex liners rated for gas and oil appliances, sized precisely to your boiler or furnace output rather than the oversized masonry cavity left from coal conversion. Last winter we relined a shared chimney on Barnes Avenue that served two attached two-family homes. The original clay tiles were cracked from decades of coal-to-gas conversion, letting acidic condensate seep into both units. We installed a 6-inch DuraFlex stainless steel liner to solve the chronic backdrafting and protect both families. In Van Nest’s attached rows, this is often the only way to bring a shared chimney into safe, code-compliant operation without rebuilding the entire structure.
Flexible Liner Solutions
Not every Van Nest chimney runs straight. The offset flues common in 1920s–1940s construction—built around stairwells and party walls—need a liner that can navigate bends without losing draft performance. Flexible liners handle those offsets while maintaining the correct diameter for your appliance. We specify flexible solutions only where rigid won’t fit, because draft efficiency matters in low-temperature gas systems. If your Van Nest rowhouse has a kinked or offset flue, we’ll tell you straight whether flexible is necessary or if a rigid stainless run is achievable.
Liner Replacement
When clay tiles have cracked, shifted, or spalled from freeze-thaw damage, spot repair is usually a Band-Aid. Full liner replacement removes the failed material and installs a continuous, properly sized flue that matches your current fuel type. In Van Nest, we see this need constantly: gas appliances venting into flues designed for 1,200°F coal exhaust, where the lower temperatures never properly dry the masonry, accelerating acidic condensate damage. Replacement typically runs $2,200–$4,000 for a standard two-story Van Nest attached home, depending on flue length and access.
Partial Chimney Rebuild
The exposed chimney crowns on Van Nest’s older rowhouses take the worst of the Bronx freeze-thaw cycle. Temperatures cross freezing multiple times each winter, water penetrates mortar joints, and the surface layer of brick spalls off. A partial rebuild addresses crown deterioration, loose brick, and failed mortar above the roofline without tearing down the entire stack. This preserves the structural shell while we install the new liner below. For Van Nest homes with sound lower masonry but crumbling crowns, partial rebuild plus liner replacement is often the most cost-effective path to full safety compliance.

Trusted Brands We Service in Van Nest
We use HeatShield for ceramic flue resurfacing where the clay tile is sound but porous, and Gelco and Olympia Chimney components for caps and termination hardware that actually fit Van Nest’s narrow chimney profiles. Famco supplies our custom-fabricated flashing and storm collars for the irregular rooflines common on these older two-families. We stock standard liner diameters and fittings locally, so Van Nest jobs don’t wait on shipping. When Gary specifies a material, it’s because that product has proven itself on hundreds of real installations—not because it’s what the distributor pushed that month.
Common Chimney Liner & Rebuild Problems We See in Van Nest Homes
- Oversized coal-era flues with gas appliances. Your 1920s chimney was sized for coal combustion at 1,200°F. Your modern gas boiler runs cooler. That temperature mismatch means exhaust stays wet longer, condensing acidic moisture that eats clay tiles from the inside out. We see this in nearly every Van Nest inspection.
- Freeze-thaw spalling on exposed crowns. The Bronx’s freeze-thaw cycle—temperatures swinging above and below freezing repeatedly through winter—destroys mortar and brick faces on chimney crowns. Once the crown fails, water enters the cavity and accelerates liner collapse.
- Shared party-wall chimneys with undetected liner cracks. Because so many Van Nest homes share party walls with their chimneys running through or adjacent to them, a collapsed or cracked flue liner is not a single-family problem—backdrafting CO can migrate laterally into neighboring units through mortar gaps, a hazard NYC DOB chimney inspection and liner requirements specifically target but that many owners in these attached rows don’t realize applies to their shared masonry.
- Clay tile shift from decades of thermal cycling. Original liners in Van Nest’s housing stock have survived 80–100 years of heating seasons. The expansion and contraction eventually gaps the mortar between tiles, creating channels for combustion gases to escape the flue entirely.
Pricing for Chimney Liner & Rebuild in Van Nest, NY
| Service | Typical Range in Van Nest |
|---|---|
| Stainless steel liner installation (standard flue) | $2,200 – $3,800 |
| Flexible liner with offset navigation | $2,800 – $4,200 |

| Chimney inspection with video scan | $175 – $250 |
These ranges reflect Van Nest’s typical two-story attached and semi-detached construction with standard roof access. Taller stacks, multiple flues, or shared party-wall configurations requiring coordination with adjacent owners can push costs toward the higher end. What drives price most: flue length, liner diameter and material, whether we can reuse the existing crown, and how much mortar and brickwork needs attention above the roofline. We don’t guess from the street. Every quote starts with a full inspection and video scan so you see exactly what we see.

FAQs — Chimney Liner & Rebuild in Van Nest
Cracked liners in shared Van Nest chimneys can vent carbon monoxide into adjacent units through mortar gaps, a hazard that NYC DOB chimney laws specifically target in these attached rows. You may not smell it or see smoke—CO is odorless and colorless—but it migrates laterally through deteriorated party-wall masonry. We inspect shared flues with video cameras that document condition for both parties, and we coordinate liner replacement to protect all units served. If you suspect a shared chimney problem, call (844) 660-6590 for an inspection—we’ll assess the full flue, not just your side.
Yes, almost certainly. Coal-era flues in Van Nest’s 1920s–1940s housing are typically three to four times larger than modern gas appliances require. That oversizing causes chronic low-temperature operation, moisture accumulation, and acidic condensate that destroys clay tiles and mortar. A properly sized stainless steel liner corrects the draft, eliminates condensation damage, and brings your chimney into compliance with current fuel-type requirements. Gary can confirm the exact sizing during inspection. Call (844) 660-6590 to schedule—estimates are free.
A partial rebuild fixes crown-area spalling and mortar failure if the structural brick and internal wythes below are sound—which we verify with hammer testing and visual inspection. Full rebuild becomes necessary when deterioration extends multiple courses below the roofline, or when the chimney leans, shows major cracking, or has compromised structural integrity. In Van Nest’s freeze-thaw climate, we catch many crowns early enough that partial rebuild plus liner replacement solves the problem. We’ll tell you honestly which category you’re in after inspection. Call (844) 660-6590 for an assessment.
Annual inspection is the standard for active heating systems in the Northeast, but Van Nest’s severe freeze-thaw cycle and coal-era flue mismatch make pre-season checks especially critical. We recommend inspection every September before heating season, with video scan documentation so you can track year-to-year deterioration. Catching crown spalling or tile cracking early prevents the water infiltration that accelerates liner collapse through winter. Schedule your pre-season inspection at (844) 660-6590.
Intermittent backdrafting in Van Nest homes usually traces to an oversized flue that can’t establish consistent draft at low gas-appliance temperatures, especially on windy days or when indoor-outdoor pressure differentials shift. The coal-era masonry cavity is simply too large for modern gas exhaust to warm and rise properly. A correctly sized stainless steel liner—typically 5 or 6 inches for residential gas boilers—creates the velocity and temperature needed for reliable draft. If you’re experiencing backdrafting, don’t wait for it to worsen. Call (844) 660-6590 and we’ll diagnose whether liner sizing is the culprit.
