Why Bohemia Homes Are Different
Bohemia’s postwar suburban boom built thousands of ranch homes and Cape Cods with single-flue masonry chimneys designed to serve both a wood-burning fireplace and an oil-fired furnace at once. Over the past two decades, many converted to natural gas without relining, leaving cracked, undersized, or acid-contaminated clay tile liners pressed into gas-appliance service. This is a code violation that Town of Islip inspectors increasingly flag, making relining a companion to nearly every cleaning call here.
The hamlet’s inland central-Suffolk location subjects chimneys to a harder freeze-thaw cycle than coastal communities. Damp, cold air accelerates moisture infiltration through failed crowns and mortar joints on 50–70 year old brick. Heavy late-season nor’easters drive wind-driven rain horizontally into chimney tops, and the shallow roof pitches common on Bohemia’s ranches provide little protective overhang. We’ve rebuilt crowns on homes near Johnson Avenue where original mortar had turned to sand after decades of this exposure.
Chimney Repair in Bohemia
Chimney repair in Bohemia demands more than standard masonry skills. The combination of acidic condensate from gas conversions attacking liners from within, and freeze-thaw moisture penetrating failed crown caps from without, destroys brick from both directions. We recently repaired a chimney on a 1965 split-level on Lakeland Avenue where the original clay tile liner was spalling from years of acidic sulfur deposits left by the old oil furnace. The homeowner had converted to gas five years prior, and the oversized flue was creating corrosive condensate that no one had caught. Chimney Repair is what we do, and Bohemia’s housing stock is familiar territory.
Mortar Repointing & Tuckpointing
The mortar joints on Bohemia’s 1950s–1970s masonry chimneys weren’t designed to survive seventy years of Long Island freeze-thaw cycling. We grind out deteriorated mortar to proper depth and repoint with color-matched, Type-N or Type-S mortar formulated for exterior chimney exposure. Tuckpointing on a typical Bohemia ranch chimney runs $850–$1,400.
Spalling Brick Repair
Spalling is epidemic in Bohemia’s older housing stock. We find it on nearly every un-repaired chimney over forty years old in the 11716 area. Surface spalling repairs typically run $600–$1,100, while partial rebuilds of severely damaged brick courses cost $1,200–$2,400. We evaluate severity with a camera inspection before quoting.
Chimney Waterproofing
Bohemia’s inland location produces harder freezes than coastal Long Island, and the shallow-pitch roofs on local ranches expose chimney shoulders to direct rainfall. A proper waterproofing treatment with pre-application repair of minor cracks costs $350–$650 and carries a ten-year performance warranty.
Flashing Repair & Replacement
Step flashing and counterflashing are the most common leak source we find in Bohemia attics. The original galvanized flashings on postwar homes have often corroded through. We fabricate and install proper two-piece copper or stainless systems that integrate with your roofing. Flashing repair in Bohemia typically costs $400–$900.
How much does chimney repair cost in Bohemia?
Most Bohemia chimney repairs fall between $450 and $2,800, with mortar repointing at $850–$1,400 and full rebuilds ranging $4,500–$7,800. Height, accessibility, and whether liner replacement is concurrent all affect the final figure. We provide itemized, upfront pricing before any work begins. Call (888) 975-6389 for an exact quote — estimates are free.
Do I need Town of Islip approval for chimney repair in Bohemia?
Most repairs don’t require a permit, but liner replacements, structural rebuilds, and venting modifications typically do. If your repair is tied to a real-estate transaction, Town of Islip inspectors may require documentation of code-compliant flue sizing for gas conversions in older homes. We handle permit applications as part of our project scope when required.
Chimney Cleaning & Sweep in Bohemia
A typical chimney cleaning and sweep in Bohemia runs $180–$320 for a standard Level 1 inspection and sweep, with Level 2 camera inspections running $300–$520 depending on access. Most appointments are scheduled within 2–3 business days, and we carry the liners, caps, and sealants needed to resolve problems on the spot. If you’re on Lakeland Avenue, Johnson Avenue, or anywhere in the 11716 zip, Gary Murphy handles the work personally.
Level 1 Inspection & Sweep
A Level 1 inspection examines readily accessible portions of the chimney exterior, interior, and connecting flue. For the ranch homes dotting Bohemia’s streets off Lakeland Avenue, this often reveals first warning signs: a crown hairline crack, a damper that won’t fully open, or creosote glazing that standard brushing won’t touch. A Level 1 inspection with standard sweep runs $180–$320.
Level 2 Camera Inspection
Level 2 is where we deploy the camera, and in Bohemia it’s where we earn our keep. Required for home sales, fuel changes, or suspected damage, this internal video scan reveals what no flashlight can. Last winter, we swept a 1965 split-level on Benson Avenue where the homeowner had converted from oil to gas five years ago but left the old clay liner. Our Level 2 inspection found spalled tiles and a cracked crown. Chimney Cleaning & Sweep with camera documentation gives you facts, not guesses.
Creosote & Soot Removal
Bohemia’s wood-burning households produce creosote at rates that surprise newer residents. Stage 1 brushes off clean; Stage 2 requires rotary chains; Stage 3 demands chemical treatment and mechanical removal. Stage 2–3 creosote removal runs $280–$450. Soot from gas appliances is finer and more acidic, especially in converted homes where an oversized liner produces condensate that mixes with residual sulfur deposits.
How often should I have my chimney cleaned in Bohemia?
The NFPA recommends annual inspection for all chimneys; active wood-burning fireplaces in Bohemia should be swept annually, and gas-venting systems inspected at the same interval. Given the age of local housing stock and prevalence of oil-to-gas conversions, we advise not extending beyond twelve months. Call (888) 975-6389 to set a recurring annual appointment.
My Bohemia home converted from oil to gas — do I need a chimney relining?
Yes, almost certainly. Your clay tile liner was sized for oil combustion and is likely damaged by acidic sulfur deposits from decades of oil service. Gas appliances produce cooler, wetter exhaust that condenses in oversized flues, creating corrosive conditions and improper draft. We inspect Bohemia conversions like yours weekly; most require a stainless steel liner sized to the gas appliance’s BTU output.
Fireplace Services in Bohemia
Fireplace services in Bohemia typically run $180–$650 depending on whether you need a gas insert tune-up, damper repair, or full relining after an oil-to-gas conversion. If your home was built during Bohemia’s postwar boom between the 1950s and 1970s, your chimney likely has a clay tile liner that served both your fireplace and your old oil furnace. That shared-flue setup creates problems most generalist repair crews simply don’t recognize.
Gas Fireplace Service
Bohemia’s gas fireplace conversions from the 2000s and 2010s are reaching the age where burner ports clog, pilot assemblies fail, and venting problems emerge. A typical gas fireplace service runs $180–$320 and includes burner cleaning, thermocouple testing, gas pressure verification, and draft assessment. We check for sulfur staining that indicates your liner spent decades serving an oil furnace.
Wood-Burning Fireplace Restoration
The original wood-burning fireplaces in Bohemia’s 1960s ranches and Cape Cods were built with throat dampers and clay tile liners sized for open-hearth drafting. After decades of disuse or conversion, these systems often have cracked firebrick, deteriorated smoke chambers, and dampers frozen by rust. A full restoration typically ranges from $450 for firebox repair and damper replacement to $2,800–$4,500 if relining is required for safe wood-burning use. Fireplace Services from us include honest assessment of whether your chimney can safely return to wood service.
Damper Repair & Replacement
Original spring-loaded throat dampers from Bohemia’s postwar construction era are now 50–70 years old. We’ve found them rusted solid, missing pivot pins, or warped from heat cycling. Damper repair costs $180–$340 if the assembly can be rebuilt; full top-sealing damper replacement runs $650–$950 installed. The top-sealing option seals the flue at the crown, keeping out wind-driven rain that accelerates mortar decay.
Can I run my gas fireplace and gas furnace into the same flue?
No — current NFPA 211 and manufacturer requirements prohibit common venting of gas appliances into a single flue, and the sizing is almost always wrong anyway. Your old oil furnace and fireplace shared a large flue designed for high-temperature oil draft; gas appliances need smaller, properly sized liners. We’ll size each appliance independently and install separate liners or a properly engineered common vent where code allows.
My gas fireplace produces a strong odor — is that from the chimney?
The odor is usually combustion spillage or residual deposits heating up, both pointing to a venting problem. In Bohemia’s converted homes, the most common cause is an oversized flue that can’t establish proper draft for a low-BTU gas insert, allowing exhaust to linger. Another frequent cause is a cracked clay liner or failed crown letting water into the flue. Call (888) 975-6389 for diagnosis.

Chimney Cap & Crown in Bohemia
A chimney cap and crown repair in Bohemia typically costs between $275 and $1,850 depending on whether you need a simple coating, cap replacement, or full crown rebuild. We carry DuraFlex and Copperfield caps on our trucks, so Bohemia homeowners aren’t waiting on parts. If you’re seeing water stains on your ceiling near the fireplace, or chunks of mortar on your roof, the crown is the first place we look.
Cap Installation & Replacement
New cap installation runs $275–$550 for a standard stainless single-flue unit, and $650–$1,200 for a multi-flue cap. Most homes off Orville Drive and in the Lakeland section have shallow roof pitches that offer little protection from wind-driven rain. Cap replacement often reveals deeper problems: rusted dampers, cracked crown edges, or spalling brick where the old cap leaked for years. Replacement with removal of the failed unit runs $325–$675. Chimney Cap & Crown work is preventive maintenance that pays for itself by avoiding rebuild costs.
Crown Repair & Coating
Crown repair addresses what we see constantly on 1960s and 1970s construction: concrete crowns poured too thin, without proper overhang or drip edge, now cracked and letting water straight into the structure. A partial crown repair runs $450–$850; full crown rebuilds range $1,100–$1,850. For crowns that are cracked but structurally sound, coating runs $350–$575 and can add five to ten years of service life.
Why do Bohemia homes with gas conversions need new chimney caps?
Gas conversions often leave the original oversized oil flue unlined, producing corrosive condensate that weakens mortar and cracks crowns from within. The existing cap may have been removed during conversion and never properly replaced, or it may no longer seal against a deteriorated crown. We check the flue condition and cap fit together on every call.
How does a crown coating help a 1960s ranch chimney in Bohemia?
A crown coating adds a waterproof, flexible membrane that bridges hairline cracks and stops water infiltration without the cost of full rebuild. For a 1960s ranch with sound structural brick but surface deterioration from decades of acidic exposure, this is often the right middle-ground repair. The coating breathes, so trapped moisture escapes instead of building up behind a sealed surface.
Chimney Liner & Rebuild in Bohemia
Chimney liner installation and chimney rebuilds in Bohemia typically run $2,800–$8,500 depending on scope. If your Bohemia home still vents a gas conversion through an old oil flue, you’re likely running a code violation that Town of Islip inspectors flag during real-estate transfers. Gary Murphy makes the trip to Bohemia himself, not a subcontractor.
Stainless Steel Liner Installation
Bohemia’s oil-to-gas conversions demand stainless steel liners sized precisely for the new appliance’s BTU output and draft requirements. The old clay tiles were engineered for 1950s oil furnaces, not the cooler, condensing flue gases of modern gas boilers. We install rigid and flexible stainless liners from DuraFlex, sized to NFPA 211 standards. Standard gas boiler liner installation runs $2,800–$4,200; flexible liners for offset flues in split-levels run $3,200–$4,800.
Liner Replacement & Relining
Full liner replacement usually follows one of three paths: cracked clay tile spalling into the flue; an undersized liner from a previous gas conversion; or acid-contaminated clay incompatible with new stainless. We remove the damaged liner when accessible, or break it out section by section if locked in place. Liner replacement with clay tile removal runs $3,500–$5,500. Every relining includes a video scan before and after. Chimney Liner & Rebuild work is documented for permit compliance.
Partial & Full Chimney Rebuild
When freeze-thaw cycles and decades of oil-furnace sulfur exposure have compromised more than just the liner, we rebuild. Partial rebuilds address the firebox, smoke chamber, or above-roof stack and run $4,500–$7,000. Full rebuilds handle chimneys where structural masonry is failing, ranging $6,500–$8,500. We match existing brick where possible and specify proper crown slope and overhang to shed water.
My 1960s home had a single chimney for fireplace and oil furnace — do I need a new liner for gas?
Yes — switching to gas without relining is a code violation and safety hazard. The old clay tiles are sized for oil-furnace exhaust temperatures and will produce corrosive condensate with cooler gas flue gases, accelerating liner failure and risking carbon monoxide spillage. We inspect, size, and install the proper stainless liner as part of every gas conversion we touch.
I’m selling my house and the inspector flagged the chimney liner — can you meet my deadline?
We can typically inspect and estimate within 24–48 hours in Bohemia, and most liner installations complete in one day. We understand Town of Islip inspection timelines and real-estate closing pressure. We stock DuraFlex and HeatShield materials so we’re not waiting on delivery while your buyer’s attorney asks questions. Call (888) 975-6389 for an exact quote — estimates are free.
