Why Hicksville Homes Are Different
Hicksville is a textbook post-WWII Nassau County boom suburb. Virtually the entire residential stock was built between roughly 1947 and 1965 as Cape Cods, ranches, and split-levels, most with masonry chimneys originally designed to serve oil burners. Decades of oil-to-gas conversions, mandated or incentivized by PSEG Long Island, left thousands of those original terra cotta-lined flues either retrofitted without proper relining or simply abandoned. Chimney cleaning calls in Hicksville almost routinely surface cracked liners, improper flue sizing for the new appliance, or sealed-off but unlined oil flue openings that now pose carbon monoxide risks.
The climate here adds its own layer of trouble. Hicksville sits in interior Nassau County, exposed to humid continental winters with repeated freeze-thaw cycles that accelerate mortar joint deterioration in aging brick chimneys. The modest but real maritime influence from Long Island Sound, roughly 10-12 miles north, adds enough salt-laden air to speed oxidation of metal flue components and chase covers compared to fully inland markets. Original terra cotta flue tiles of that era are at or past their service life and show high rates of cracking and spalling under Nassau County inspection standards.
Many Hicksville homes from the 1950s were built with a two-flue chimney chase - one for the fireplace, one for the oil burner - and when oil systems were removed, contractors commonly bricked over the oil flue opening inside the basement without capping the flue at the top. Technicians doing a routine cleaning frequently pull the damper and find an unsecured interior flue that has never been properly addressed.
Chimney Repair in Hicksville
Chimney repair in Hicksville is rarely a simple matter of patching what you see. The housing stock’s age, the conversion history, and the local climate mean we almost always find interconnected problems: a cracked crown letting water into spalled brick, an abandoned oil flue accelerating deterioration of the active flue, or improper gas conversion sizing creating condensation that destroys mortar from within. We document everything with our Level-2 camera, show you photos you can see, and give you a plain-English verdict before any work begins. Our Chimney Repair crews carry professional-grade materials from Copperfield and Olympia Chimney, and most repairs finish in a single visit.
Chimney Rebuilding
We rebuild from the roofline up or perform partial rebuilds of deteriorated courses, using matching brick and professional-grade materials. A full rebuild on a Hicksville Cape Cod typically runs $3,500-$6,500; partial rebuilds of the top 3-5 courses start around $1,800. We complete most rebuilds in 1-2 days.
Mortar Repointing
The mortar in a 1950s Hicksville chimney has endured 60-75 winters of expansion and contraction. Once joints recede past a half-inch, water infiltrates the wall cavity and the freeze-thaw cycle begins destroying brick from within. Our repointing matches original mortar composition and compressive strength, not a quick tuck with whatever’s in the truck. Typical repointing on a Hicksville chimney runs $1,200-$2,400 depending on access and extent. Done right, it buys you another 30 years.
Flashing Repair
Hicksville’s two-flue chimneys often have complex step-flashing geometries where the chimney meets a low-slope ranch roof or a Cape Cod’s steep pitch. Failed flashing is the single most common source of “we thought it was the roof” leaks. We fabricate custom flashing from heavy-gauge material and seal with professional-grade compounds. Most flashing repairs in Hicksville run $450-$950 and are completed in a single visit.
Spalling Brick Repair & Waterproofing
Spalling, brick faces popping off from water trapped inside, is epidemic in Hicksville’s older chimneys. The maritime air accelerates it. We remove damaged brick, install matching replacements, and apply breathable waterproofing agents that stop water intrusion without trapping moisture inside. Spalling repair with waterproofing typically runs $800-$1,800. Waterproofing alone, as preventive maintenance on sound masonry, runs $350-$550.
My Hicksville home was built in the 1950s and has two flues - one for the fireplace and one for the old oil burner. The oil flue is bricked over in the basement but not capped at the roof. Is this safe?
No. An open, unlined flue shaft drafts moisture and debris directly into your chimney structure and can allow carbon monoxide or combustion gases to migrate between flues. We inspect this condition constantly in Hicksville’s two-flue chases and seal abandoned flues properly with appropriate materials per code. Call (855) 950-3861 for a free estimate.
How do I know if my original terra cotta flue tiles are cracked?
You usually cannot see flue tile cracks from the firebox or roof without a camera. Our Level-2 inspection uses a video scanner to document every inch of the flue - photos you can see, a plain-English verdict. Warning signs include white efflorescence staining on exterior brick, a persistent smoky odor when the fireplace is not in use, or pieces of terra cotta in the firebox.
Chimney Cleaning & Sweep in Hicksville
A typical chimney cleaning and sweep in Hicksville runs $180-$320 for a standard Level 1 service, with Level 2 camera inspections running $350-$550. Most cleanings are completed in a single visit, and our technicians carry the equipment to handle the legacy flue issues common to Hicksville’s post-war housing stock. We know these chimneys: the two-flue chases with abandoned oil flues, the cracked terra cotta from decades of freeze-thaw, the improper sizing after PSEG Long Island conversions. Our Chimney Cleaning & Sweep service starts with inspection, not assumptions. Call (855) 950-3861 anytime - a live person answers, 24 hours a day.
Level 1 Inspection & Sweep
A Level 1 inspection is the standard annual check for chimneys that have not changed and are performing normally. In Hicksville, we often perform these on 1950s ranches and Cape Cods where the fireplace has seen light seasonal use. We examine the readily accessible portions of the chimney exterior, interior, and flue, check for obstructions and combustible deposits, and verify basic structural soundness. Cost typically runs $180-$250.
Level 2 Camera Inspection
Level 2 inspections are where we find what other sweeps miss. Using a high-resolution camera, we inspect the entire flue interior from top to bottom, and in Hicksville, we almost always find something worth documenting. The freeze-thaw cycles of interior Nassau County beat hard on 60-year-old mortar joints. Salt-laden air from Long Island Sound speeds oxidation of metal components that newer suburbs simply do not face. Level 2 camera inspection runs $350-$550.
Creosote & Soot Removal
Creosote builds up in every wood-burning flue, but Hicksville’s older chimneys often have additional complications. Undersized flues from oil-to-gas conversions can create poor draft, causing smoke to linger and creosote to accumulate faster than it should. Abandoned flues that draw cold air can chill the active flue, reducing draft velocity and worsening condensation. We use professional-grade brushes and vacuum systems, and for glazed creosote that resists standard sweeping, we apply HeatShield products to break down the deposit safely. Heavy creosote removal in Hicksville typically runs $280-$420 depending on buildup severity.
My 1950s Hicksville home has two flues - one sealed in the basement. Do I need both cleaned?
Yes, both flues need attention, though not necessarily the same service. The active fireplace flue requires regular sweeping and inspection. The abandoned oil flue, if it was bricked over in the basement but left open at the top, needs to be capped and inspected for debris accumulation and structural integrity. We find this exact condition constantly in Hicksville’s two-flue chases. Call (855) 950-3861 and we will check both - estimates are free.
How often should I get my chimney cleaned in Hicksville given the freeze-thaw cycles?
Annual cleaning and inspection is the minimum for Hicksville homes, and we recommend it without exception for chimneys over 60 years old. The freeze-thaw cycles of interior Nassau County accelerate mortar deterioration, and the only way to catch spalling flue tiles or crown cracks before they become hazardous is to look every year. If you burn wood more than three times per week during heating season, consider mid-season checks as well.
Fireplace Services in Hicksville
Fireplace service in Hicksville typically runs $180-$650 depending on whether you need a routine cleaning, damper adjustment, or full firebox rebuild, and our technicians complete most jobs in a single visit with upfront pricing before any work begins. The fireplaces in these post-war homes were built for a different era of heating, and 60-75 years of use has taken its toll on refractory panels, dampers, and flue liners. Our Fireplace Services team carries the parts and materials to handle the legacy chimney systems common here, from gas burner replacements to full firebox rebuilds. Call (855) 950-3861 - a live person answers, 24 hours a day.
Gas Fireplace Service
Gas fireplaces in Hicksville’s 1950s and 1960s homes often sit in original masonry fireboxes that were never designed for gas inserts. The burner ports clog with dust, the pilot assemblies corrode from that maritime-influenced air, and the venting frequently ties into chimney flues that were improperly sized when the oil furnace was converted. We clean burners, test gas pressure, inspect venting with our Level-2 camera, and flag any flue sizing mismatch before it becomes a carbon monoxide issue. A standard gas fireplace service in Hicksville runs $180-$280.
Wood-Burning Fireplace Restoration
The wood-burning fireplaces in Hicksville’s Cape Cods and ranches were built for a different era of heating. After 60-75 years, the original terra cotta flue tiles are at or past their service life, cracking and spalling under repeated Nassau County freeze-thaw cycles. We see this constantly in homes near the 11801 and 11815 ZIP codes. Our wood fireplace service includes a full Level-2 camera inspection, creosote removal, and a written verdict on whether your flue liner can be repaired with HeatShield or needs full relining with DuraFlex. Expect $220-$380 for standard service.
Firebox Repair & Damper Service
Damper failure is one of the most common calls we get in Hicksville, and it’s often the first clue to a deeper problem. We serviced a 1957 split-level on Newbridge Road where the homeowner reported smoke backing up; dropping the damper revealed a bricked-over oil flue opening in the basement, the old flue had never been capped at the top, allowing debris to pile up and block the fireplace flue. Firebox repair in Hicksville ranges from $450 for panel replacement to $1,800-$2,800 for full rebuilds.
My Hicksville home was built in 1955 with a two-flue chimney. Do I need to worry about the old oil flue even if I don’t use it?
Yes. An uncapped oil flue draws cold air and debris into your chimney structure, and we’ve found these blockages causing smoke to back up into living rooms. The opening may have been bricked over in your basement while the top was left open to the weather. We inspect both flues with our camera, cap abandoned flues properly, and seal them against water and pest intrusion. Call (855) 950-3861 and we’ll assess both.
Can I convert my wood-burning fireplace to a gas insert in an older Hicksville home?
Usually, yes, but the chimney must be evaluated first. Original flues in 1950s Hicksville homes are often oversized for modern gas inserts, and the terra cotta may be cracked. We install a properly sized liner as part of the conversion, ensuring safe venting and proper draft. The complete project typically runs $2,800-$4,500. We’ll inspect first and tell you exactly what your chimney needs.

Chimney Cap & Crown in Hicksville
Chimney cap and crown repair in Hicksville typically runs $280-$890 depending on whether you need a simple cap replacement or full crown rebuild, and most jobs are completed in a single visit. We’re familiar with the post-war Cape Cods, ranches, and split-levels that define Hicksville’s neighborhoods, from the homes near Hicksville station down Jerusalem Avenue to the quiet streets off Old Country Road and the Cantiague Park area. The crowns on these 60-75-year-old chimneys have endured repeated freeze-thaw cycles and salt-laden air from Long Island Sound; by the time you see interior water staining, the crown is often beyond simple patching. Our Chimney Cap & Crown service measures precisely, fabricates to fit, and seals against the weather Hicksville actually gets. Call (855) 950-3861 - a live person answers, 24 hours a day.
Multi-Flue Cap Installation
Hicksville’s two-flue chimneys demand specific solutions. Many homes built between 1947 and 1965 have one flue for the fireplace and a second for an oil burner that’s long gone. On a recent job near the Hicksville station on Jerusalem Avenue, we found a cracked crown and an uncapped secondary flue from a removed oil burner. We sealed the abandoned flue, installed a custom multi-flue cap from Olympia Chimney, and applied a HeatShield crown coating to prevent freeze-thaw damage. Multi-flue custom caps for these common configurations typically cost $480-$720.
Crown Repair & Rebuild
Original mortar crowns on post-war homes are past their service life. Sixty to seventy-five years of humid continental winters, with repeated freeze-thaw cycles and salt-laden air from Long Island Sound, have spalled and cracked most of them. We remove the deteriorated crown down to sound masonry, form a new concrete crown with proper drip edges and slope, and seal it against the flue with expansion joints that move with the chimney. Full crown removal and rebuild runs $680-$1,240.
Crown Coating & Cap Replacement
When crown damage is caught early, before water has saturated the brick below, a professional-grade crown coating can add years of protection. We use HeatShield and other professional-grade materials, never builder-grade substitutes. Standard single-flue stainless steel cap installation runs $280-$450. For Hicksville homes with legacy terra cotta flue tiles, we verify the tile condition before capping; a cracked tile capped over will only trap moisture and accelerate deterioration.
My Hicksville home was built in 1955 with two flues; one was for the oil burner that’s now gone. Do I need a special cap for the abandoned flue?
Yes, you need a multi-flue cap that seals the abandoned flue permanently, not just a cap on the active fireplace flue. Leaving the abandoned flue open at the top allows rain, debris, and cold air to enter the chimney structure, accelerating crown deterioration and creating a path for carbon monoxide if the seal inside the basement ever fails. We typically seal the abandoned flue with a proper termination and install a cap sized to your exact chase dimensions.
After a PSEG Long Island gas conversion, my chimney crown cracked. Is that related?
Often yes. Improper flue sizing after conversion is a leading cause of premature crown failure in Hicksville. Gas appliances produce more water vapor than oil burners, and if the flue was not properly relined for the new appliance, that excess condensation saturates the crown from the inside, then freezes and expands during Hicksville’s cold snaps. We inspect the flue sizing and crown condition together, because coating or rebuilding a crown without fixing the underlying condensation problem is temporary at best.
Chimney Liner & Rebuild in Hicksville
If your Hicksville home was built between 1947 and 1965, your chimney is likely 60 to 75 years old. A stainless steel liner installation in Hicksville typically runs $2,800-$4,500, while a partial rebuild starts around $3,500 and a full chimney rebuild can reach $8,000-$15,000 depending on height and access. The original terra cotta flue tiles in these chimneys are at or past their service life, and the oil-to-gas conversion history here means we frequently find oversized flues, abandoned oil flues left open at the crown, and improper appliance connections that fail Nassau County standards. Our Chimney Liner & Rebuild service starts with a Level-2 camera inspection - photos you can see, a plain-English verdict - and we give you the full price before any work begins. Call (855) 950-3861 - a live person answers, 24 hours a day.
Stainless Steel Liner Installation
Most Hicksville chimneys need a stainless steel liner. The original terra cotta flue tiles in your 1950s Cape Cod or ranch have reached the end of their service life. Spalling, horizontal cracking, and flue gas erosion are standard findings in our Level-2 inspections here. We install DuraFlex stainless steel liners, sized precisely for your current heating appliance. A proper 7-inch liner for a gas furnace retrofit corrects the oversizing that causes condensation damage in converted oil chimneys. In Hicksville, a stainless steel liner installation typically runs $2,800-$4,500.
Liner Replacement & Flexible Liners
If your existing liner has failed - corrosion, separation at joints, or improper original sizing - we remove and replace it. Hicksville’s maritime-influenced climate, with salt-laden air from Long Island Sound roughly 10 miles north, accelerates oxidation of lower-grade metal components. We replace with professional-grade DuraFlex, properly sized and sealed. Liner replacement in Hicksville runs $2,200-$4,000 depending on flue length and accessibility. For chimneys with offset flues or tight clearances, flexible liners navigate obstacles without dismantling chimney sections.
Partial & Full Chimney Rebuild
When the upper courses of brick, the crown, or the flue surround are compromised but the lower structure is sound, a partial rebuild is the right call. In Hicksville, we commonly rebuild crowns and the top 4 to 6 feet of chimney on 1950s ranches where freeze-thaw cycling has destroyed mortar joints. The abandoned oil flue opening, often left uncapped at the crown, accelerates this deterioration by allowing water and debris directly into the stack. Partial rebuilds in Hicksville start around $3,500 and typically top out at $6,500. When the structure is failing from the roofline down, a full rebuild on a typical Hicksville ranch or Cape Cod runs $8,000-$15,000.
My Hicksville home was built in 1952 and has a bricked-over oil flue in the basement. Is that a safety hazard?
Yes, it often is. If the oil flue was bricked over at the basement level but left open at the crown, you have an uncapped shaft that drafts cold air, moisture, and debris directly into your chimney structure. This creates a potential carbon monoxide pathway and accelerates mortar deterioration. We inspect this condition with our Level-2 camera and seal it properly with a chase cover or full rebuild as needed.
Do I need a full rebuild or can I just reline my 1950s chimney?
Most Hicksville chimneys can be relined if the exterior brick and structure are sound. We recommend a full rebuild when there’s extensive spalling brick, compromised lateral stability, or multiple flue failures throughout the structure. Our Level-2 inspection gives you photos and a plain-English verdict so you can decide with confidence. Call (855) 950-3861 for an exact assessment.
