Anthony Perez, our owner and lead technician, handles the work personally. Eight years in chimney-only service means we’ve seen what Bohemia’s oil-heat legacy and salt-air climate do to mid-century masonry. Call (833) 719-7193 for a free estimate.
Why Premier Chimney Cleaning Connecticut Is Bohemia’s Preferred Chimney Repair Company
800+ homeowners have reviewed us at a 4.7-star average, and a solid share of those jobs came from central Suffolk County — Bohemia included. Anthony leads every job, so the person quoting your chimney is the same one on the ladder. No subcontractors, no seasonal hires.
We’re familiar with Bohemia’s housing stock because we’ve worked it repeatedly: the 1950s–1970s Cape Cods, ranches, and split-levels with original single-flue masonry chimneys now pushing 50–70 years. Those chimneys were built for oil-fired boilers, not gas conversions or fireplace inserts, and that matters for diagnostics.
Response time to Bohemia is typically same-day or next-day. We’re already making runs through Ronkonkoma and Holbrook, so your job doesn’t sit in a dispatch queue.
From annual sweep to full rebuild, we handle the complete chimney lifecycle. That depth matters in Bohemia, where oil-flue acid damage often escalates from a cracked liner to spalling brick to structural compromise if it’s patched by a generalist who misses the root cause.
Our Chimney Repair Services in Bohemia
Mortar Repointing
Bohemia’s freeze-thaw cycles hit hard. The humid maritime air off the Great South Bay, combined with winter temperature swings, forces moisture into mortar joints, expands it, and crumbles the bond. On a ranch home near Washington Avenue, we found the original 1960s terracotta liner riddled with hairline cracks from decades of oil-flue acid. We installed a DuraFlex stainless steel liner in a single trip, sealing the top with a heavy-duty cap sized for the homeowner’s detached workshop door opener clearance. Mortar repointing in Bohemia runs $450–$950 for a standard single-flue stack, using a custom-matched mix with waterproofing additive formulated for salt-air exposure.
Spalling Brick Repair
Spalling — the flaking and face-loss of brick — is epidemic on Bohemia’s mid-century chimneys. Salt air carried inland from the South Shore accelerates the damage compared to inland Suffolk neighborhoods. We don’t just patch with surface sealers. We cut out spalled units, match replacement brick for color and absorption, and address the moisture source. Spalling brick repair in Bohemia typically costs $650–$1,400, depending on how many courses are affected and whether the crown is the culprit.
Chimney Waterproofing
Standard crown mixes fail within 2–3 winters on Bohemia’s salt-air-exposed chimneys. We spec a waterproofing additive and extra freeze-thaw cycling protection. For the full chimney body, we apply a vapor-permeable silane/siloxane treatment that lets moisture escape while blocking salt-laden rain. Acreage properties with detached workshops need particular attention — those secondary chimneys often get neglected until water stains appear on the workshop ceiling. Chimney waterproofing in Bohemia runs $350–$750 for application, or $800–$1,600 if crown rebuild with additive is included.
Flashing Repair
Cape Cods and ranches dominate Bohemia, and many have 6/12 pitch roofs where step flashing meets the chimney saddle. The constant expansion and contraction from temperature swings loosens the seal. We replace with copper or lead-coated copper, not aluminum that fatigues. Flashing repair in Bohemia typically runs $400–$900.
Chimney Rebuilding
When acid-etched liners, spalled brick, and compromised mortar converge, partial or full rebuild becomes the only safe option. We rebuild with matching brick, proper flue sizing for your current heating system, and a stainless steel liner if the original terracotta is shot. Full chimney rebuilding in Bohemia starts around $2,200 and can reach $5,500+ for taller stacks on split-levels.

Trusted Brands We Service in Bohemia
We use DuraFlex, HeatShield, and Famco — the same materials specified by chimney industry professionals, not hardware-store substitutes. For Bohemia’s oil-heat chimneys, DuraFlex stainless steel liners handle acidic condensate that destroys terracotta. HeatShield’s cerfractory resurfacing works when the liner is structurally sound but surface-eroded. Famco caps and accessories in stainless or copper resist the salt-air perforation that kills galvanized hardware in four years. We stock common sizes, so most Bohemia jobs don’t wait on parts.
Common Chimney Repair Problems We See in Bohemia Homes
- Acid-etched terracotta liners go undiagnosed. Magnetic sweep heads miss sulfate deposits — only camera inspections catch the deterioration oil heat produces. We camera every Bohemia chimney before quoting repair.
- Crown cracks from freeze-thaw cycling. Bohemia’s maritime humidity means more water intrusion, more expansion, more concrete failure. Standard mixes don’t survive.
- Spalling brick from salt-air exposure. South Shore salt carried inland eats mortar and brick faces faster than in central Long Island. The damage starts at the top and works down.
- Oversized caps rusting through. Galvanized caps on acreage properties with detached workshops show perforation within four years. We upgrade to stainless or copper.

FAQs — Chimney Repair in Bohemia
Wood-burning flues show creosote buildup that’s visible to a sweep brush; oil-heat flues hide acid erosion inside terracotta joints that brushing can’t reach. We camera every oil-heat chimney in Bohemia because sulfate deposits and hairline cracks from decades of acidic condensate are invisible without it. Call (833) 719-7193 to schedule a camera inspection — estimates are free.
No. Gas appliances require a properly sized, intact liner; a 1960s terracotta liner sized for oil draft is almost certainly too large and too damaged for safe gas venting. We inspect, measure, and install a correctly sized stainless steel liner if conversion is your goal. Anthony can walk you through the sizing and code requirements on-site. Call (833) 719-7193 for a free evaluation.
Yes. Workshop chimneys in Bohemia are often shorter, exposed on all sides, and built with less overhang protection, so they take more direct weather. We rebuild workshop crowns with a steeper slope, heavier drip edge, and the same salt-air-rated additive we use on main stacks. The repair typically runs $600–$1,100 depending on flue count. Call (833) 719-7193 for an exact quote.
A vapor-permeable silane/siloxane sealer, not a film-forming acrylic that traps moisture. We apply it to clean, dry masonry after any repointing or spall repair, and we add a waterproofing agent to crown rebuilds. The treatment lasts 7–10 years in Bohemia’s climate. Call (833) 719-7193 to schedule — estimates are free.
Yes. Cape Cods with 6/12 pitches are common in Bohemia, and we regularly replace step flashing and counterflashing on these roofs. The angle requires precise bending and longer lap joints to prevent wind-driven rain intrusion. We use copper or lead-coated copper, not aluminum. Typical cost is $400–$900. Call (833) 719-7193 for a free estimate.
