Fast, Reliable Chimney Repair Across Bohemia
Chimney repair in Bohemia typically runs $450–$2,800 depending on scope, and most jobs are completed in a single day. We carry DuraFlex liners, HeatShield refractory mortar, and professional-grade crown sealants on every truck, so we’re not making a second trip to fix your flue.
We’re familiar with the 11716 zip code and the surrounding central Suffolk corridor.

Gary Murphy, our owner and lead technician, has spent 14 years in this trade — not as a generalist, but exclusively on chimneys. He handles every Bohemia call personally. If you’re seeing crumbling mortar, water stains on your ceiling, or white efflorescence blooming on your brick, call (888) 975-6389 for a free estimate. We’ll give you a straight answer and a firm price before any work starts.
Why Sterling Chimney Cleaning Bridgeport Is Bohemia’s Preferred Chimney Repair Company
More than 1,200 homeowners have trusted us with their chimneys, and our 4.7 average star rating across 1,234 verified reviews reflects the kind of repeat business you only earn by showing up prepared and finishing clean. Bohemia customers aren’t looking for the cheapest sweep in Suffolk County — they’re looking for someone who recognizes that their 1968 Cape Cod has an original clay liner sized for an oil furnace that was decommissioned fifteen years ago.
Our response time to Bohemia is typically same-day or next-morning, because we keep our trucks stocked with the materials that matter here: DuraFlex stainless liners for gas conversions, HeatShield cerfractory foam for resurfacing degraded flues, and Copperfield professional-grade waterproofing compounds formulated for freeze-thaw climates like central Suffolk’s. We don’t dispatch subcontractors. Gary Murphy is the person who diagnoses your chimney, climbs your roof, and signs off on the repair. That accountability is why Bohemia homeowners call us back when their neighbors need a referral.
We also understand the local inspection landscape. Town of Islip building inspectors have tightened scrutiny on chimney conditions during real-estate transfers, and we’ve completed enough pre-sale repairs in Bohemia to know what they’ll flag before they do. That local knowledge saves you a failed inspection and a delayed closing.
Our Chimney Repair Services in Bohemia
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. On homes near the Great South Bay’s influence zone, we’ve found accelerated joint failure where prevailing winds drive rain into the northeast faces — we address that with proper joint profiling and, when needed, supplementary waterproofing. Tuckpointing on a typical Bohemia ranch chimney runs $850–$1,400.
Spalling Brick Repair
Spalling — the flaking and crumbling of brick faces — is epidemic in Bohemia’s older housing stock. 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 ago, and the oversized flue was creating condensation damage. We installed a DuraFlex stainless steel liner to meet code and prevent further deterioration. Surface spalling repairs start around $600; partial rebuilds of severely damaged courses run $1,200–$2,400.
Chimney Waterproofing
Bohemia’s inland location doesn’t protect your chimney from moisture — it subjects it to a harder freeze-thaw cycle than coastal communities, where maritime temperatures moderate winter lows. We apply vapor-permeable, professional-grade waterproofing agents that allow the masonry to breathe while blocking liquid water penetration. This is critical on the shallow-pitch roofs common to Bohemia’s ranches, where minimal overhang exposes the chimney shoulder 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 around chimney penetrations are the most common leak source we find in Bohemia attics. The original galvanized flashings on postwar homes have often corroded through, and previous “repairs” with roofing cement or caulk are temporary at best. We fabricate and install proper two-piece copper or stainless flashing systems that integrate with your roofing — not just seal over it. Flashing repair in Bohemia typically costs $400–$900 depending on roof pitch and accessibility.
Chimney Rebuilding
When deterioration exceeds repair economics, we rebuild from the roofline up or complete full-height reconstruction using matching brick and proper structural reinforcement. Bohemia’s soil conditions and foundation settling patterns are familiar territory — we’ve rebuilt chimneys on homes from the original Bohemia development tracts that required integrated structural solutions, not just cosmetic rebuilds. Partial rebuilds start at $2,200; full rebuilds range $4,500–$7,800.

Trusted Brands We Service in Bohemia
We don’t source from hardware store shelves. Our trucks carry DuraFlex stainless steel and aluminum liners, HeatShield cerfractory resurfacing systems, and Copperfield professional-grade waterproofing and repair compounds — the same brands specified by chimney professionals nationwide. For Bohemia homeowners, that means no waiting on special orders for standard repairs. When Gary Murphy arrives to inspect your chimney, he’s already carrying the materials your repair likely requires. That stock-on-hand discipline is how we complete most Bohemia repairs in a single visit, including same-day liner installations that would take other companies a week to schedule and supply.
Common Chimney Repair Problems We See in Bohemia Homes
- Oversized clay liners venting gas appliances. Bohemia’s oil-to-gas conversions have left thousands of homes with flues designed for 500°F oil exhaust now handling 120°F gas condensate. The acidic moisture eats mortar joints from within and destroys liner integrity — a condition Town of Islip inspectors increasingly flag during real-estate transfers.
- Freeze-thaw crown cap failure. Bohemia’s genuine inland freeze-thaw cycle — harder than coastal Long Island — cracks aging crown caps, allowing water to infiltrate and trigger brick spalling. We find this on nearly every un-repaired chimney over forty years old in the 11716 area.
- Rusted damper assemblies. The cast-iron throat dampers original to 1950s–1970s Bohemia construction are commonly rusted shut or warped beyond operation, trapping moisture in the flue and accelerating liner decay. Replacement with a stainless top-sealing damper solves the problem permanently.
- Acid-contaminated clay tile from dual-service history. Chimneys that served both oil furnaces and wood fireplaces carry decades of sulfuric acid residue in their liners. Once the oil burner is removed, this residue continues degrading the clay, often revealed only when the gas conversion inspector mandates a Level 2 internal evaluation.

FAQs — Chimney Repair in Bohemia
Your clay tile liner was sized for the 500°F exhaust of an oil furnace, and it’s now handling the cooler, moisture-laden exhaust of a gas appliance. The oversized flue allows exhaust to cool too quickly, producing corrosive condensate that degrades mortar joints and liner surfaces from the inside out. This is the most common hidden chimney failure we find in Bohemia’s converted ranch homes, and it’s why we recommend a Level 2 inspection with any fuel conversion. Call (888) 975-6389 to schedule — estimates are free.
Most chimney repairs in Bohemia do not require a permit, but liner replacements, structural rebuilds, and any work involving appliance venting modifications typically do. If your repair is tied to a real-estate transaction or renovation, Town of Islip inspectors may require documentation of code-compliant flue sizing — especially for gas conversions in older homes. We handle permit applications as part of our project scope when required. Call (888) 975-6389 and we’ll clarify whether your specific repair needs filing.
Surface spalling repairs in Bohemia typically run $600–$1,100, while partial rebuilds of severely damaged brick courses cost $1,200–$2,400. The price depends on how many courses are affected, whether the underlying liner is also compromised, and whether crown cap replacement is needed to prevent recurrence. We evaluate spalling severity with a camera inspection before quoting. Call (888) 975-6389 for an exact assessment — estimates are free.
Yes, and we typically recommend replacing a rusted throat damper with a stainless steel top-sealing damper rather than attempting repair. The original cast-iron dampers in Bohemia’s 1950s–1970s Cape Cods are usually corroded beyond reliable operation, and a top-sealing damper provides a better seal, improved energy efficiency, and easier operation. Installation runs $450–$750 depending on flue size and accessibility. Call (888) 975-6389 to schedule.
Yes — Bohemia’s inland freeze-thaw cycle is harder on masonry than coastal Long Island’s moderated temperatures, and the shallow roof pitches on local ranches provide minimal chimney protection from wind-driven rain. Professional waterproofing is vapor-permeable (it doesn’t trap moisture inside the brick) and prevents the liquid water infiltration that triggers spalling and joint failure. At $350–$650 with a ten-year warranty, it’s preventive maintenance that pays for itself by avoiding rebuild costs. Call (888) 975-6389 to add waterproofing to your next service.
