We’ve worked the 11222 zip code for 17 years, and Greenpoint’s tight street grid — Manhattan Avenue, Nassau Avenue, the side streets between Driggs and Greenpoint Avenue — means we’re rarely more than 15 minutes from your door. We know the parking constraints, the narrow alley-load entries, the three-story brick rowhouses built shoulder-to-shoulder. Robert Garcia, our owner and lead technician, handles every repair call himself. You’re not getting a dispatched crew from a franchise hub. You’re getting the person whose name is on the company, climbing your roof, reading your flue, and standing behind the repair.

Greenpoint’s chimneys are not like Brooklyn’s elsewhere. The neighborhood’s late-Victorian and Edwardian-era working-class rowhouses — built between roughly 1885 and 1925 for Polish and Italian immigrant laborers — carry original coal-era unlined single-wythe brick chimneys that were crudely adapted for oil burners in the 1940s through 1960s. Now, as a gentrifying ownership class reactivates these as wood-burning fireplaces, we’re seeing a three-fuel-generation chimney history — coal to oil to wood — on un-relined, century-old stacks. This is Greenpoint’s defining chimney repair challenge, distinct from the brownstone belt further south. Our Chimney Repair team has rebuilt, relined, and repointed more of these transitional flues than any other specialist in North Brooklyn.

Why Apex Chimney Cleaning Greater New York Is Greenpoint’s Preferred Chimney Repair Company

Robert Garcia has spent 17 consecutive years on Greenpoint roofs. He knows the salt-laden humidity rolling off the East River and Newtown Creek, the way it accelerates mortar joint erosion faster here than in inland Brooklyn neighborhoods. He knows which rowhouses on Kent Street still share chimneys across two or three units, and which buildings on Franklin Street were converted from No. 2 fuel oil to gas without proper decommissioning. That knowledge changes what we find, how we repair it, and what we charge.

Our reputation in 11222 is documented: 1,096 verified customer reviews averaging 4.7 stars. Greenpoint homeowners specifically mention Robert by name in their feedback — the accountability of having the owner on the ladder, not a subcontractor checking a box. We’re state-licensed, insured & bonded, and we carry professional-grade materials from DuraFlex, HeatShield, and Copperfield on our truck, so most repairs don’t wait for parts.

Response time matters in Greenpoint’s dense housing. A compromised chimney in a two-family rowhouse on Monitor Street doesn’t just affect one unit — it affects the boiler venting for the apartment above, the fireplace below, sometimes a third flue for a water heater. We prioritize same-day inspection calls when water is actively entering or a flue is blocked. Most standard repair assessments happen within 48 hours.

Our Chimney Repair Services in Greenpoint

Mortar Repointing

Greenpoint’s freeze-thaw cycles are brutal on century-old mortar. Salt-laden humidity from the East River and Newtown Creek saturates the joints; winter cold exploits them. We’ve repointed chimneys on Java Street where the mortar was powdering after just 18 months because previous contractors skipped waterproofing — a critical step we never omit. Our repointing runs $850–$2,200 for a typical Greenpoint rowhouse chimney, depending on access height and joint depth. We grind to a proper depth, match the historic mortar composition, and seal with a vapor-permeable treatment formulated for marine-exposed masonry.

Spalling Brick Repair

Spalling — the flaking and crumbling of brick faces — is epidemic on Greenpoint’s waterfront-exposed stacks. We see it worst on roofs facing west toward the East River, where driving rain and salt spray hit year-round. On a recent job near the intersection of Greenpoint Avenue and West Street, we replaced 34 spalled bricks on a 1905 rowhouse chimney and installed a new concrete crown with proper drip edges. Spalling repair in Greenpoint ranges $1,200–$3,800. Left untreated, spalling compromises structural integrity and invites water into the flue system.

Chimney Rebuilding

Sometimes repointing and brick replacement aren’t enough. When a chimney has suffered structural settlement, catastrophic water intrusion, or — most commonly in Greenpoint — dangerous multi-flue configurations that violate current NYC DOB code, we rebuild from the roofline up or perform a full tear-down and reconstruction. We recently repointed the crown and installed a DuraFlex liner for a 1901 rowhouse on Driggs Avenue where the landlord had abandoned an old oil flue without decommissioning it, and the new gas boiler was venting into the same tile liner as the parlor fireplace upstairs — a code violation that required full chimney rebuilding. Full rebuilds in Greenpoint typically run $3,500–$8,500. We use Copperfield components and HeatShield refractory mortar where appropriate, installed to current NYC building code.

Chimney Waterproofing

Waterproofing is non-negotiable in 11222. The marine microclimate here means unsealed masonry absorbs moisture continuously, then freezes, expands, and destroys itself. We apply vapor-permeable waterproofing agents that allow the brick to breathe while repelling liquid water — critical for century-old masonry that needs to dry seasonally. A standard waterproofing treatment runs $450–$950 for a Greenpoint rowhouse chimney. We won’t repoint or rebuild without recommending this protection.

Flashing Repair

Step flashing and counterflashing on Greenpoint’s low-slope rowhouse roofs take abuse from thermal expansion and wind-driven rain. We repair or replace flashing where it meets the chimney structure, using lead or copper as appropriate to the building’s era. Flashing repair typically runs $350–$850. On older Greenpoint homes, we often discover that original flashing was tarred over repeatedly instead of properly replaced — a shortcut that traps moisture and rots roof decking.

Trusted Brands We Service in Greenpoint

We install and work with professional-grade materials from DuraFlex, HeatShield, Gelco, and Copperfield — the same product lines specified by commercial masonry contractors. For Greenpoint’s century-old chimneys, this matters. A DuraFlex stainless steel liner, properly sized and insulated, can safely vent a modern wood-burning fireplace through a coal-era flue that was never designed for it. HeatShield’s cerfractory resurfacing system lets us restore eroded clay tile liners without a full tear-out, preserving historic masonry while meeting current safety standards. We stock common components on our service vehicle, so most Greenpoint repairs don’t wait for a parts run. When a specialized order is needed — a custom Gelco cap for an oversized multi-flue chimney, for instance — we coordinate direct delivery to minimize downtime.

Common Chimney Repair Problems We See in Greenpoint Homes

• Salt-accelerated mortar erosion. Greenpoint’s position between the East River and Newtown Creek exposes chimneys to salt-laden humidity from two waterways. We’ve repointed chimneys on Dupont Street where the mortar was crumbling after just two years because no waterproofing was applied — a failure mode we rarely see this aggressively in inland Brooklyn neighborhoods.
• Abandoned oil flues venting new appliances. Landlords who converted boilers from No. 2 fuel oil to gas in the last decade often left the old flue un-decommissioned. We regularly find that same chimney now venting a restored parlor fireplace upstairs through a compromised, oil-sooted tile liner — a setup that fails NYC Local Law inspection and creates real carbon monoxide risk in multi-family units.
• Multi-unit flue cross-contamination. Two- and three-family rowhouses frequently share a single chimney stack across multiple flues serving different units. Creosote from an active fireplace can migrate through cracked partition walls into a neighbor’s boiler flue, requiring thorough cleaning and structural flue separation repairs before any unit can operate safely.
• Cracked clay tiles glazed with mixed creosote and oil-soot. The mid-century oil conversion era left Greenpoint with clay tile liners (where present) that are cracked and coated with a stubborn, hybrid deposit. This material can reignite at lower temperatures than pure wood creosote, elevating chimney fire risk in buildings now returning to wood-burning use.
