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.

AfterFast, Reliable Fireplace Services Across Dyker Heights
Fireplace service in Dyker Heights typically runs $180-$450 depending on whether you need a basic cleaning, gas log adjustment, or firebox repair, and most appointments are completed in a single visit with our technicians carrying the parts they need. We dispatch to Dyker Heights from our New York City office, and our crews know the neighborhood’s brick homes from 84th Street down to the Narrows - the semi-detached and detached houses built during the 1920s through 1940s that define this part of southwestern Brooklyn.
These houses have a specific problem. Most were built with coal-fired heating systems and later converted to oil, then gas, often without proper chimney relining. The original clay tile flues are still in place, carrying decades of mixed-fuel residue, and many have never had a professional camera inspection. That is why we start every Dyker Heights job with a Level-2 camera inspection - photos you can see, a plain-English verdict - before any work is recommended. Call (516) 613-3035 to book. A live person answers, 24 hours a day.

Why Hearthstone Chimney Co. Is Dyker Heights’s Preferred Fireplace Services Company
We have been serving Brooklyn homeowners for over 42 years, and Dyker Heights has been part of that route since the beginning. The neighborhood’s large brick homes, many passed down through Italian-American families who take pride in their holiday traditions, require a sweep who understands coal-era construction - not a technician reading from a generic checklist.
Our technicians are background-checked, uniformed, and carry professional-grade materials from brands like HeatShield and DuraFlex on every truck. Most jobs are completed in a single visit. Our pricing is agreed upfront - the number on the estimate is the number on the invoice.
Every job is backed by our 90-Day Done Right Promise, in writing with no arguing. If it is not right, we come back. That is the Keystone Standard, and it has governed our work since 1984.
Russell Haines, our owner, built this company on the belief that a homeowner should never have to take a contractor’s word without proof. In Dyker Heights, where multi-generational owners are often told they need thousands of dollars in relining work based on a flashlight glance, that principle matters more than ever.
Our Fireplace Services in Dyker Heights
Gas Fireplace Service
Gas log sets and direct-vent fireplaces are common upgrades in Dyker Heights’s older homes, but they are often installed incorrectly. We regularly find gas inserts dropped into fireboxes still venting through original coal-era clay flues, with dampers rusted open or removed entirely. Our gas fireplace service includes combustion analysis, burner cleaning, pilot and thermocouple testing, and a full camera inspection of the flue to verify it is the correct type and size for gas exhaust. If the flue is unsuitable, we document it on camera and explain the options - no recommendation without evidence you can see.
Wood Burning Fireplace
The wood-burning fireplaces in Dyker Heights’s 1920s-1940s homes were built for coal-era draft patterns and often draw poorly by modern standards. Add decades of creosote buildup from occasional holiday fires, and you have a system that smokes back into the room or burns inefficiently. We rod-brush and HEPA-vacuum the flue, inspect the firebox for cracked mortar or missing bricks, and check the damper operation. Because Dyker Heights sits close to Upper New York Bay, salt-laden air accelerates mortar joint erosion, so we also examine exterior masonry for spalling and water intrusion that can affect draft.
Fireplace Insert
Installing a fireplace insert in a Dyker Heights home requires more than sliding a metal box into an existing opening. The original firebox and flue were sized for open-hearth combustion, not the controlled burn of an insert. Without proper sizing and a compatible stainless liner, the insert can overheat, produce dangerous creosote buildup, or vent carbon monoxide into wall cavities. We measure the firebox, run a camera to assess flue condition, and specify the correct insert and liner combination using DuraFlex or Olympia Chimney components. Most installations are completed in one day, with the old damper sealed or modified as required.
Damper Repair
Dampers in Dyker Heights’s older chimneys are often original cast-iron units that have rusted open, rusted shut, or warped from decades of heat cycling. A damper stuck open wastes heated air all winter and allows rain and animals into the flue. A damper stuck shut traps smoke and carbon monoxide in the home. We inspect the damper mechanism, repair or replace it with a correctly sized unit, and verify full opening and closing range. In homes where the damper was removed during a previous conversion, we can install a top-sealing damper that improves energy efficiency and keeps weather out.
Firebox Repair
The firebox in a 1930s Dyker Heights brick home takes decades of thermal cycling, and the refractory mortar between firebricks eventually crumbles. We repoint fireboxes with HeatShield refractory materials rated for direct flame exposure, replace cracked or spalled firebricks, and verify that the firebox walls maintain proper clearance to combustible framing. This is not cosmetic work - a compromised firebox can allow heat transfer to wall studs, creating a slow-motion fire hazard that shows no visible flame.
Fireplace Conversion
Converting a wood-burning or coal-era fireplace to gas in Dyker Heights requires verifying that the flue can handle gas exhaust temperatures and moisture, or installing a dedicated vent system if it cannot. We handle the gas line coordination, burner and log set specification, and all flue modifications, with every step documented by camera inspection. The conversion is not complete until the system is tested and the homeowner has seen the inspection photos.
Trusted Brands We Service in Dyker Heights
Our trucks carry professional-grade materials from DuraFlex, HeatShield, Gelco, and Olympia Chimney - the brands we specify for our own homes, not builder-grade substitutes that fail in five years. Because we stock these parts locally, most Dyker Heights repairs are completed in a single visit without waiting for special orders. When a firebox needs refractory repair, we use HeatShield. When a flue needs relining, we use DuraFlex or Olympia Chimney stainless steel liners sized to the appliance, not a one-size-fits-all coil. This is how the job is done right, and how we stand behind it.
Common Fireplace Problems We See in Dyker Heights Homes
- Gas log sets vented through coal-era clay flues. The original flue was never designed for the cooler, wetter exhaust of a gas appliance. Condensate mixes with decades of coal dust and old creosote, forming a baked-on residue that no standard brush will clear. We find this on camera, then specify the correct stainless liner or venting solution.
- Dampers rusted open or missing entirely. Salt air from the Narrows accelerates corrosion of cast-iron dampers, especially in homes where the chimney crown has cracked and allowed water intrusion. A rusted-open damper is an energy leak and a water entry point; a missing damper is a code violation and a safety hazard.
- Two-flue chimneys with unchecked mortar erosion. Many Dyker Heights homes have one flue for the heating system and another for the fireplace. Homeowners focus on the fireplace flue and forget the heating flue, but they share exterior masonry. When mortar joints erode from salt air and freeze-thaw cycling, both flues are compromised. Our inspection covers the entire chimney, not just the firebox you can see.
- Firebox refractory mortar turned to sand. After ninety years of heating and cooling, the mortar between firebricks crumbles. Gaps allow heat to reach combustible wall framing. This is not visible from the living room, and it is why we inspect every firebox with a bright light and a mirror, then photograph what we find.

FAQs - Fireplace Services in Dyker Heights
Yes. Even occasional burning produces creosote, and in Dyker Heights’s older chimneys, that creosote layers onto decades of existing residue from coal and oil conversion. Annual inspection catches buildup before it becomes a hazard, and the NFPA recommends yearly Level-2 inspection for all masonry chimneys regardless of use frequency. Call (516) 613-3035 to schedule before the holiday rush.
That black coating is typically a mixture of first-degree creosote, oil-flue condensate, and fossilized coal dust from the original heating system. When your home converted from coal to oil or gas, the flue was often left unlined, and the new fuel produced different exhaust that bonded to the old residue. It is a common finding in Dyker Heights, and it is why we camera-inspect before cleaning - to determine whether brushing alone is sufficient or whether the liner needs replacement. Call (516) 613-3035 and we will show you exactly what is in your flue.
Often yes, but only after camera verification that the flue is suitable or can be lined correctly. The holiday-display rush in Dyker Heights means our October and November schedule fills quickly, so planning ahead matters. We measure the firebox, assess the flue, and specify the insert and liner combination in one visit. Most installations are completed in a single day once parts are confirmed. Call (516) 613-3035 to reserve a pre-holiday appointment.
It should be addressed before you use the fireplace, but it is not an emergency unless you are actively burning. A stuck-open damper allows heated air to escape continuously, drives up heating bills, and admits rain and animals. In Dyker Heights’s salt-air environment, the rust causing the jam will only worsen. We can typically free or replace the damper in one visit. Call (516) 613-3035 to book.
Buildup speed depends on wood moisture, burn temperature, and draft quality, but Dyker Heights’s older chimneys have an additional factor: restricted draft from coal-era flue dimensions and deteriorating mortar joints. Poor draft produces cooler fires and more creosote. Most of our Dyker Heights customers who burn regularly need annual sweeping; those who burn only during the holidays may stretch to every two years, but the inspection should still be yearly. Call (516) 613-3035 and we will assess your specific burn pattern.
At a semi-detached brick home off 84th Street, an owner had a gas log set dropped into a firebox that still fed into the original coal-era clay flue, and our tech ran a camera up first: the flue liner was coated in baked-on first-degree creosote and fossilized coal dust, with the damper rusted open - a set-up that would have drafted smoke straight back into the room. We documented it on camera for the homeowner, HEPA-vacuumed and rod-brushed the flue, freed the damper, and fitted a correctly sized HeatShield stainless liner, with a first-degree creosote note for the next annual sweep before the holiday displays went up.
Dyker Heights’s fireplace rush is seasonal in a way no neighboring Brooklyn neighborhood shares: multi-generational owners time their first cleaning in years to the December Christmas-light display season, so late-October through November is the only window when these 1920s-1940s coal-era flues get looked at. The result is clay tile liners carrying oil-flue condensate layered over decades-old coal dust, with no prior inspection on record. If you live in one of these homes, the condition of your flue is unknown until a camera shows it. That is why our Fireplace Services team starts every Dyker Heights job with documented evidence, not a sales pitch.
