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.

Why Hearthstone Chimney Co. Is Rego Park’s Preferred Chimney Cap & Crown Company
Rego Park homeowners and co-op boards call us because we show up understanding what we’re looking at. Most chimney companies in the tri-state area are built around single-family fireplace flues - a technician drives up from Nassau or down from Westchester expecting a brick chimney with a damper and a firebox. In Rego Park, that technician is walking into a 1950s co-op with a shared masonry stack serving a central oil-fired boiler room, and the job stalls before it starts.
We’ve built our reputation in Rego Park on doing the job correctly the first time, with no surprises on the bill. Our Level 2 camera inspections end with photos you can see and a plain-English verdict - documented like an engineer, explained like a craftsman. The 90-Day Done Right Promise backs every job in writing: if it’s not right, we make it right, no paperwork and no arguing. Background-checked, uniformed technicians complete most jobs in a single visit, and our no-hassle upfront pricing means the number on the estimate is the number on the invoice.
Calls are answered by a live person, 24 hours a day, 7 days a week - not a voicemail, not a callback queue. We’ve been serving local communities since 1984, and we plan to be here in thirty more years. That changes how we treat every job.
Our Chimney Cap & Crown Services in Rego Park
Multi-Flue Cap Installation
Most Rego Park chimneys aren’t residential fireplace flues at all - they’re shared multi-flue masonry stacks serving a single oil-fired boiler in 1940s-1960s co-op and rental buildings, so a cap-and-crown job here is a commercial-class, building-wide scope requiring DOB filing and super/property-manager coordination, not a one-home sweep. We measure the full stack, fabricate a multi-flue cap with proper clearances for all active flues, and install it with stainless-steel anchoring rated for Queens wind exposure. Every installation includes the signed DOB filing package your board or property manager needs.

Crown Repair
The flat lime-mortar crown on Rego Park’s postwar brick stacks has taken a beating. Queens’ freeze-thaw cycle - multiple temperature swings across the freezing point each winter - is particularly hard on these older lime-mortar joints and brick crowns, causing spalling and open joints that allow moisture intrusion into shared flue systems serving the whole building. We were called to a six-story 1950s co-op off Queens Boulevard near the 63rd Drive corridor after a top-floor unit reported water stains tracking down the wall beside the flue. Our tech ran a Level 2 inspection with camera, found the original terra cotta flue liner cracked and separated after six decades of thermal cycling, the lime-mortar crown spalled wide open from the freeze-thaw swings, and no cap at all on a shared multi-flue stack. We installed a custom multi-flue cap with a DuraFlex liner assembly and rebuilt the crown, giving the super and board a signed DOB filing package and the camera footage they could forward to every shareholder.

Custom Cap Fabrication
Standard big-box caps don’t fit Rego Park’s irregular multi-flue configurations. We fabricate custom caps to exact stack dimensions, with welded seams and proper slope for drainage - critical in a neighborhood where the high relative humidity from the position between Flushing Bay and Jamaica Bay watersheds accelerates deterioration between inspections. Custom caps in Rego Park typically run $1,200-$2,400 installed, depending on stack size and access.

Crown Coating
For crowns with surface cracking but sound structural integrity, we apply a professional-grade flexible crown coating - not the hardware-store brush-on products that fail in two seasons. This buys time for boards budgeting a full rebuild, and we document the crown’s condition with camera footage so you know exactly what you’re getting. Crown coating in Rego Park runs $650-$1,100, with a clear written assessment of expected service life.

Trusted Brands We Service in Rego Park
We work exclusively with professional-grade materials from DuraFlex, HeatShield, Gelco, and Olympia Chimney - no builder-grade substitutes. For Rego Park’s shared boiler stacks, that means DuraFlex liners rated for the temperature swings of oil-to-gas conversion, Gelco multi-flue caps with proper mesh screening against Queens’ leaf and debris load, and HeatShield crown repair products that flex with the thermal expansion these stacks see daily. We stock common sizes locally, so most Rego Park jobs don’t wait on parts.
Common Chimney Cap & Crown Problems We See in Rego Park Homes
- Uncapped shared stacks letting rain directly into oil-boiler flues. The original shared multi-flue chimney stack was never capped, letting rain directly into oil-boiler flues and accelerating terra cotta liner separation in a building where a liner failure means a boiler shutdown for every unit. We see this constantly in the 1940s-era buildings along Yellowstone Boulevard and the 63rd Drive corridor.
- Spalled lime-mortar crowns from decades of freeze-thaw. The flat lime-mortar crown on 1940s-1960s brick stacks has spalled and opened at the joints after 60-plus winters of Queens freeze-thaw, and because the crown is shared, one open joint becomes a moisture path into the whole building’s flue system. The high humidity between Flushing Bay and Jamaica Bay watersheds makes this worse than in drier parts of Queens.
- Out-of-borough crews quoting single-family scope for building-wide stacks. Out-of-borough crews quote a cap-and-crown job as a single-family scope, then discover the stack serves a central boiler room and needs a multi-flue commercial-class cap plus DOB filing - the job stalls and the board is left with an exposed, leaking stack. We’ve been called in to finish jobs that sat open for months after this exact scenario.
- Terra cotta liner separation hidden until camera inspection. Older terra cotta tile liners in Rego Park’s stacks have commonly cracked or separated after 60-plus years of thermal cycling. A separated liner behind an apparently sound crown is a carbon monoxide and fire risk for the whole building - and it’s invisible without a Level 2 camera inspection.

FAQs - Chimney Cap & Crown in Rego Park
Yes. Rego Park’s shared multi-flue stacks require commercial-class multi-flue caps with proper clearances for all active boiler flues, not the single-flue caps sold at hardware stores. A cap that blocks or undersizes one flue can back exhaust into boiler rooms or neighboring units. Call (516) 531-6315 and we’ll measure your stack correctly.
Not necessarily, but it’s often the smartest timing. Oil flues are oversized for gas exhaust, so conversion requires relining - and relining requires a sound crown and proper cap to protect the new liner. Doing cap, crown, and liner together avoids scaffolding twice and gives your board one DOB filing instead of two. We can inspect now and phase the work to your board’s budget cycle. Call (516) 531-6315 for a camera inspection and written phasing plan.
The camera tells the truth. We run a Level 2 inspection and show you the footage - spalling depth, joint separation, and whether water is reaching the flue liner. A coating works for surface cracking with sound structure underneath. A rebuild is needed when the crown has lost structural integrity or water has penetrated to the liner. You’ll see the difference yourself before we recommend either. Call (516) 531-6315 to schedule.
Queens sees multiple freeze-thaw cycles each winter - temperatures cross 32°F repeatedly, sometimes within a single day. Water enters micro-cracks in lime mortar, expands when it freezes, and widens those cracks with every cycle. Rego Park’s position between Flushing Bay and Jamaica Bay means higher ambient humidity, so more moisture is available to enter. After 60-plus years, this spalls the crown surface and opens joints that become pathways into the whole building’s flue system. Call (516) 531-6315 for an inspection if your building’s crown is original to the structure.
Most cannot, and we’ve been called to fix the results. Rego Park’s shared boiler stacks require DOB filing for repairs on buildings of this class, multi-flue commercial-grade caps, and coordination with supers or property managers - not the single-family scope most suburban chimney companies are equipped for. A technician expecting a fireplace flue will discover a boiler room stack and stall. We handle the filing, the fabrication, and the board communication. Call (516) 531-6315 - estimates are free.
