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.

Our Fireplace Services in St. George
Gas Fireplace Service
Gas fireplaces in St. George’s converted brownstones and row houses often sit in hearths originally built for coal, with flues that were never properly resized for modern gas inserts. We inspect the burner assembly, check gas pressure at the valve, and verify that your venting meets current NYC DOB standards. In harbor-exposed properties near the Ferry Terminal, we also inspect for corrosion on vent terminals where salt air accelerates metal fatigue.
Wood Burning Fireplace
Original wood-burning fireplaces in St. George’s late-Victorian housing stock are beautiful, but many draw through coal-era flues with cracked mortar and no proper liner. We perform Level 2 camera inspections to assess creosote buildup, flue integrity, and whether your chimney can safely handle regular wood fires. If third-degree creosote is present, we’ll explain what we found and recommend the right course of action, documented with photos you can see for yourself.
Fireplace Insert
Fireplace inserts are our most frequent recommendation for St. George homeowners with drafty, inefficient original fireplaces. We size and install inserts from trusted brands including DuraFlex and HeatShield, with stainless steel liners that isolate your firebox from shared masonry stacks. This is especially critical in attached row houses where adjacent flues may carry neighbor’s appliance exhaust. Our insert installations include a camera-verified liner pull, proper termination above the roofline, and a written 90-Day Done Right Promise.
Damper Repair
St. George’s harbor air corrodes cast-iron dampers faster than inland locations. A stuck or rusted damper wastes heat, invites downdrafts, and can allow carbon monoxide to back up into living spaces. We repair or replace throat and top-sealing dampers, using components from Gelco and Olympia Chimney that withstand salt-air exposure. Most damper repairs are completed in a single visit with upfront pricing agreed before we start.
Firebox Repair
Cracked firebox panels or deteriorating refractory mortar in St. George’s century-old fireplaces aren’t cosmetic issues. They’re heat and CO hazards. We rebuild fireboxes with professional-grade materials, matching original dimensions while bringing the assembly up to modern safety standards. Every firebox repair includes a Level 2 inspection of the surrounding flue system.
Fireplace Conversion
Converting a wood-burning fireplace to gas, or updating an old oil-thimble setup to a modern vented system, requires navigating NYC DOB compliance and shared-stack realities unique to St. George’s attached housing. We handle the inspection, permitting guidance, and installation, isolating your new system with proper liners and termination. No shortcuts. No guesswork. The job done correctly, documented in writing.
Trusted Brands We Service in St. George
We don’t use builder-grade substitutes. Our trucks carry professional-grade materials from DuraFlex, HeatShield, Gelco, Olympia Chimney, Famco, and Copperfield, so most St. George repairs don’t wait on parts orders. When we recommend a HeatShield flue liner or a Gelco damper assembly, it’s because we’ve installed hundreds of them and we know how they perform in salt-air, freeze-thaw conditions like St. George’s. The right material for the right application, installed by a background-checked, uniformed technician who completes most jobs in a single visit.
Common Fireplace Services Problems We See in St. George Homes
- Shared-stack cross-contamination. In St. George’s attached row houses, adjacent properties often share a single chimney stack with multiple flues. A neighbor’s oil burner thimble or coal-era flue can vent into the same masonry mass as your fireplace, allowing exhaust odors and carbon monoxide to migrate. Our Level 2 camera inspections identify these configurations and we install proper liners to isolate each flue.
- Salt-air mortar erosion and brick spalling. St. George sits directly on New York Harbor, exposing chimney stacks to persistent salt-laden air and wind-driven moisture that accelerates deterioration at a pace inland Staten Island neighborhoods simply don’t see. We rebuild crowns, repoint mortar joints, and install proper flashing to stop water intrusion before freeze-thaw cycling destroys the stack.
- Original unlined coal-era chimneys adapted for oil heat. Many St. George properties have basement chimneys that were never properly lined when switching from coal to oil, just a thimble punched through old brick. These conversions fail current NYC Building Code standards for clearance and liner integrity, creating genuine carbon monoxide hazards that require documented remediation.
- Third-degree creosote in rarely-swept flues. In older St. George homes where fireplaces saw heavy use through past decades without regular sweeping, glazed creosote builds into a hard, ignitable layer that standard brushing won’t remove. We identify the severity during camera inspection and recommend appropriate mechanical or chemical treatment, never pushing unnecessary work.

And the condition of existing flue liners, which we assess with our camera before quoting, never after starting work. We provide no-hassle upfront pricing, the number on the estimate is the number on the invoice, and estimates are free. Call (516) 613-3035 for yours.

FAQs - Fireplace Services in St. George
Yes, this is a documented hazard in St. George’s attached row houses where multiple flues share one masonry stack without proper liner isolation. We find this configuration regularly on Bay Street and the Ferry Terminal blocks, where a neighbor’s oil thimble was punched through the same brick mass as the fireplace flue. Our Level 2 camera inspection maps the flue separation, and we install a dedicated stainless steel liner to isolate your fireplace from adjacent exhaust. Call (516) 613-3035 to schedule - estimates are free.
Salt-laden air from New York Harbor corrodes cast-iron dampers and accelerates refractory mortar deterioration faster than in inland Staten Island neighborhoods. We replace rusted dampers with corrosion-resistant assemblies from Gelco and repair firebox mortar with materials rated for freeze-thaw cycling. Most of this work is completed in a single visit with upfront pricing. Call (516) 613-3035 for a free inspection.
Third-degree creosote is a hard, glazed, highly combustible deposit that forms when wood smoke condenses in cool or poorly drafted flues over years of use without sweeping. In St. George’s century-old housing stock, we encounter it frequently in fireplaces that saw heavy use through the 1970s and 1980s before natural gas conversion. It cannot be removed with standard brushing and presents a significant chimney fire risk. We identify it during camera inspection and recommend appropriate mechanical removal or chemical treatment, documented with photos you can see. Call (516) 613-3035 - we’ll show you exactly what we’re looking at.
Yes, especially in St. George. Even unused fireplaces in shared-stack row houses can admit neighbor’s exhaust, harbor moisture from harbor-air infiltration, or conceal deteriorating mortar that threatens structural integrity. An annual Level 2 inspection catches these issues before they become expensive or dangerous. Our $89 Seasonal Tune-Up includes a full safety inspection, and estimates are always free. Call (516) 613-3035 to book.
We install DuraFlex stainless steel liners and HeatShield cerfractory flue coatings for liner restoration, with fireplace inserts and components from Gelco and Olympia Chimney. These are professional-grade materials, not builder-grade substitutes, chosen for performance in salt-air, freeze-thaw environments like St. George’s. Every installation is documented with before-and-after photos and covered by our 90-Day Done Right Promise in writing. Call (516) 613-3035 for a free estimate on your insert or liner project.
On a tight street near the St. George Ferry Terminal, our tech opened a shared stack in a late-Victorian row house and found third-degree creosote glazed on the fireplace flue while the neighbor’s oil burner thimble had been punched through the same brick mass, allowing exhaust odors into the living room. We performed a Level 2 inspection, installed a HeatShield flue liner to isolate the fireplace, and rebuilt the smoke chamber - restoring proper draft and stopping the cross-contamination. Photos of the entire process went to the homeowner before we packed up. Done right, and we stand behind it.
