Why Apex Chimney Cleaning Greater New York Is Hillside’s Preferred Chimney Repair Company
We’ve earned our reputation in Hillside one stack at a time. Over 1,096 verified customer reviews averaging 4.7 stars back up what we do, and a solid share of those come from Queens homeowners who’ve watched us navigate the complications their chimneys throw at us. When you’re dealing with a shared flue system in a two-family house, you don’t want a crew that’s learning on the job.
Robert handles it himself.

Seventeen years of chimney-only focus means we’ve seen virtually every failure mode these 1920s–1950s stacks can produce.
Our response time to Hillside is same-day or next-day for most repair calls. We stock professional-grade materials — including Gelco caps, Olympia Chimney components, and Copperfield sealants — so we’re not waiting on parts while water keeps eating your mortar. Our Chimney Repair team understands the local building department requirements that apply in NYC-territory Hillside, not the looser rules that suffice in Nassau or Westchester.
Our Chimney Repair Services in Hillside
Mortar Repointing
The freeze-thaw cycles that hit Hillside every February and March don’t forgive weak mortar. On a 90-year-old shared stack, deteriorated joints between bricks become entry points for water that expands when it freezes, loosening the whole structure. We grind out failed mortar to proper depth and repoint with color-matched, weather-resistant mortar formulated for Queens’ temperature swings. On Hillside’s attached two-families, we also inspect the party-wall side that many homeowners never see — the side that’s often worst-hit because it’s harder to spot from the street.
Spalling Brick Repair
Spalling — that flaking, crumbling surface on brick faces — is epidemic on Hillside’s converted coal-era chimneys. When original clay flues weren’t properly relined for gas exhaust, condensation forms, soaks the brick from inside, and pushes the face off in sheets. We don’t just patch over it. We remove spalled units, assess whether the flue needs relining to stop the root cause, and rebuild with matching brick where possible. Last February, we repaired a shared chimney stack on 109th Avenue where the upper unit’s raw gas vent had cracked a clay tile liner, spilling carbon monoxide into the lower unit’s bedroom. We installed a DuraFlex liner through the common flue and obtained a DOB permit, also tuckpointing the crown to stop water entry.
Chimney Waterproofing
Hillside’s dense housing means chimneys sit close together, creating wind tunnels that drive rain sideways into porous brick. We apply breathable, vapor-permeable waterproofing agents — never the cheap sealers that trap moisture inside — specifically chosen for the freeze-thaw exposure these stacks face. For shared-stack buildings, we pay special attention to the vertical joints where two structures meet; these are common leak paths that standard roofers often miss.
Flashing Repair
The intersection where chimney meets roof is a failure point on every Hillside home, but it’s worse on older structures where multiple roof layers have buried original flashing or where amateur repairs have layered tar over rusted metal. We remove it properly, install new step flashing and counterflashing integrated with your roofing, and seal with high-temperature compounds. On the low-slope sections common behind Hillside’s parapet walls, we use specialized techniques to create positive drainage that prevents the ponding water that destroys standard flashing in three to five years.
Chimney Rebuilding
When a Hillside stack has deteriorated past the point where repointing or partial repair makes sense, we rebuild from the roofline up or from the foundation if necessary. This is more common than you’d think on the 1920s–1950s housing stock here, especially where decades of deferred maintenance have compounded freeze-thaw damage. Robert manages the structural assessment, the DOB filing if required, and the rebuild itself — including proper flue lining for each unit in a two-family shared stack. We source matching brick and rebuild to current code, not just to “good enough.”
Tuckpointing
For Hillside homeowners who want to preserve the original aesthetic of their interwar brickwork, tuckpointing offers a precise, decorative restoration of mortar joints. We remove deteriorated mortar and replace it with historically appropriate formulations, sometimes adding the fine white lines that give classic Queens brickwork its distinctive appearance. It’s labor-intensive work that requires steady hands and an eye for detail — the kind of job Robert personally oversees rather than delegating to a crew you’ve never met.

Common Chimney Repair Problems We See in Hillside Homes
- Unlined or improperly relined flues from coal-to-gas conversions produce condensation that spalls clay tile and blocks flues within years. These original conversions, common throughout 11432’s housing stock, leave exhaust gases too cool to rise properly, and the resulting acidic condensation literally eats the flue from inside out.
- Freeze-thaw cycles crack shared brick crowns, letting water into both flues and accelerating mortar joint decay between annual cleanings. Every February and March, we see the seasonal spike — homeowners who noticed nothing in October are calling with water stains and loose brick by March.
- Partition wall flues in attached homes allow liner deterioration to leak CO into adjacent units, often undetected until a tenant reports headaches. In Hillside’s two-family shared stacks, this isn’t a hypothetical risk — it’s a pattern we’ve documented multiple times, and it’s why we inspect the full flue system even when only one unit reports a problem.
- NYC DOB permit requirements surprise homeowners who expected a simple sweep to stay simple. Any structural repair or liner replacement in Hillside requires a licensed contractor and proper filing; crews who skip this step leave you exposed to violations, insurance issues, and failed inspections when you sell.

FAQs — Chimney Repair in Hillside
Yes, absolutely. In Hillside’s shared-stack two-families, the flues are separated by thin clay tile partitions that deteriorate over time, so a liner failure or improper installation in one flue can create carbon monoxide pathways into the adjacent unit. We always inspect the full flue system, document conditions for both units, and install separate, properly sleeved liners when needed. If your neighbor’s flue is compromised too, we’ll show you exactly what we found and coordinate access. Call (866) 884-9512 for a full-stack inspection — estimates are free.
Yes. Hillside falls under NYC Department of Buildings jurisdiction, and any chimney liner replacement or structural repair requires a licensed contractor and may require a DOB filing and inspection. Homeowners are often caught off guard when a routine sweep reveals a liner issue that triggers this requirement. We handle the filing, the scheduling, and the inspection coordination as part of our standard process — not as an afterthought that delays your project. Call (866) 884-9512 and we’ll walk you through what’s needed for your specific job.
Sometimes, but often not. Spalling that returns annually usually signals an active moisture source — typically an unlined or failed flue that’s condensing water into the brick from inside. Repointing without addressing the root cause buys you two to three years before you’re back in the same spot. We assess the flue condition first; if the liner’s compromised, we’ll quote repointing plus relining so the repair actually lasts. Seventeen years of chimney-only focus means we’ve learned to fix the cause, not just the symptom. Call (866) 884-9512 for an inspection that looks at the whole system.
Urgent enough that we flag it at every cleaning visit in Hillside. Original clay tiles sized for oil exhaust are too large for gas, which burns cooler and produces more acidic condensation. That condensation pools in the flue, attacks the mortar between tiles, and eventually spalls brick or blocks the flue entirely. We’ve seen complete flue blockages within five to seven years of conversion on Hillside’s housing stock. The risk isn’t theoretical — it’s carbon monoxide backing up into living spaces. If your conversion was more than a few years ago and the flue was never properly lined, call (866) 884-9512 for priority inspection.
No. A cracked crown can often be rebuilt or sealed with proper crown-coat material if the underlying brick structure is sound. We see this in Hillside regularly — a hairline crack from freeze-thaw gets diagnosed as “needs full rebuild” by a contractor who doesn’t do precision crown work. Robert assesses the structural integrity of the brick below, the extent of water infiltration, and whether the flue itself has been compromised. If the stack is otherwise sound, a crown rebuild or professional-grade sealant application runs $1,400–$2,800 versus $5,500+ for unnecessary full reconstruction. Get a second opinion from someone who’ll show you the actual condition. Call (866) 884-9512 for a free, no-pressure assessment.
