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.

Why Hearthstone Chimney Co. Is Lindenhurst’s Preferred Chimney Cap & Crown Company
We’ve been serving communities across this region for over 42 years, and Lindenhurst’s combination of salt air, aging masonry, and post-war housing stock is something our technicians have documented hundreds of times. Our Chimney Cap & Crown team knows that a crown that looks sound from Montauk Highway can be spider-cracked and spalling once you’re on the roof.
Homeowners here tell us the same thing: the last contractor gave a verbal estimate, showed no photos, and the problem came back inside two years. We do the opposite. Every inspection ends with photos you can see and a plain-English verdict. Our 90-Day Done Right Promise is in writing with no arguing, governed by our K.E.Y.S. values code: Krafted right, Every time, Your home first, Standing behind it.
Calls are answered by a live person, not a voicemail system or callback queue. Our technicians are background-checked and uniformed, and most jobs are completed in a single visit with no-hassle upfront pricing - the number on the estimate is the number on the invoice. We’ll be there when we say.
Our Chimney Cap & Crown Services in Lindenhurst
Crown Coating
Crown coating in Lindenhurst is often the most cost-effective way to extend the life of a chimney that’s showing early salt-air damage but hasn’t fully failed. A typical crown coating here runs $280-$450 and buys 5-10 years of protection if the underlying masonry is still structurally sound. We use professional-grade flexible crown sealants from HeatShield that can accommodate the thermal expansion and contraction these South Shore chimneys experience through freeze-thaw cycles. Before we coat anything, we perform a Level 2 camera inspection to confirm the flue liner and interior masonry are intact - coating over hidden damage is a shortcut we don’t take.
Custom Cap Fabrication & Installation
Standard off-the-shelf caps don’t fit many Lindenhurst chimneys, especially the oversized or irregular flue openings found on 1950s ranches with multiple appliances venting into a single chase. Custom stainless steel caps fabricated by our Chimney Cap & Crown in Lindenhurst specialists typically run $340-$620 installed, including proper mounting and spark arrestor screening. We work with Copperfield and Famco for custom dimensions and Gelco for standard multi-flue configurations. A proper custom cap stops rain, keeps animals out, and reduces the downdrafts that plague canal-front homes when wind comes off Great South Bay.
Multi-Flue Cap Installation
Many Lindenhurst Cape Cods and ranches have two or more flues sharing a common chimney chase - often one for a wood stove and one for a furnace or water heater. Multi-flue caps cover the entire chase with a single hood, eliminating the gaps between individual caps where water and debris collect. Installed cost in Lindenhurst runs $380-$680 depending on chase dimensions and whether we need to rebuild deteriorated brick before mounting. These caps are particularly effective for homes south of Montauk Highway where wind-driven rain would otherwise penetrate between poorly fitted single flue caps.
Crown Rebuild & Full Replacement
When a crown has spalled through to the brick below or the reinforcing wire is exposed and rusting, coating is no longer the right call. Full crown rebuild in Lindenhurst typically costs $520-$850 and involves pouring a new concrete crown with proper slope, drip edge, and expansion relief to shed water away from the masonry below. We see this need most often on chimneys that went uninspected after Superstorm Sandy’s 2012 surge, when water driven into crowns and cracked masonry set up years of hidden deterioration. Our rebuilds use professional-grade concrete mixes with air-entrainment for freeze-thaw resistance - critical for South Shore conditions.
Cap Replacement
Sometimes the crown is sound but the cap itself has failed - rusted through, blown off in a storm, or never properly installed. Standard cap replacement in Lindenhurst runs $180-$340 for a properly fitted galvanized or stainless unit with mounting hardware and screening. We inspect the crown and flue condition before installing any new cap, because putting a new cap on a failing crown is a waste of your money and our reputation.

Common Chimney Cap & Crown Problems We See in Lindenhurst Homes
- Salt-air spalling on crowns. The village’s position along Great South Bay channels salt-laden moisture onto rooftops year-round, accelerating spalling and mortar erosion on masonry chimneys well beyond what technicians see in inland Suffolk County towns. Crowns that read as sound from the street are often silently failing.
- Step flashing oxidation on canal-front ranches. On the canal-front blocks south of Montauk Highway, step flashing on 1950s ranch chimneys routinely oxidizes through in 10-15 years instead of the expected 25+, because salt spray off the canals combines with the low-slope rooflines typical of those homes.
- Post-Sandy hidden damage. Superstorm Sandy’s 2012 surge flooding drove water into chimney crowns and cracked masonry across Lindenhurst, and many of those chimneys were never fully re-inspected afterward. We still find Sandy-era damage on homes being sold for the first time since the storm.
- Cracked terra-cotta liners in converted systems. Original 1945-1965 terra-cotta flue liners crack from decades of freeze-thaw cycling and heat cycling, and homeowners switching from oil to gas rarely know the liner condition has changed. A proper cap and crown inspection includes camera verification of liner integrity.

Whether we need to repair or replace step flashing adds $120-$280. And if Sandy-era water damage has compromised the brick beneath the crown, masonry repair extends the scope.

FAQs - Chimney Cap & Crown in Lindenhurst
Lindenhurst Chimney Cleaning & Sweep starts with annual Level 2 inspection, and we recommend it every year without exception for canal-front properties south of Montauk Highway. The salt-laden moisture here accelerates crown spalling and flashing oxidation to roughly twice the rate we see 10 miles inland, so the standard “every other year” guidance doesn’t apply. Call (516) 614-4632 to schedule - estimates are free.
You need a camera inspection to know for certain, but original 1950s crowns in Lindenhurst are rarely in good shape after 60-80 years of salt air and freeze-thaw cycling. If the crown has hairline cracks but solid structure, crown coating buys time. If it’s spalling, crumbling, or the wire mesh is exposed, rebuild is the honest recommendation. We’ll show you photos and explain both options with exact pricing.
A cap helps indirectly by reducing moisture infiltration that makes creosote stickier and harder to remove, but it does not eliminate creosote buildup. For homeowners using our Fireplace Services in Lindenhurst and burning wood as primary heat, the real factors are wood moisture content (below 20%), adequate air supply, and more frequent sweeping - often annually rather than every two years. A proper cap plus correct burning practice is the combination that keeps your system safe.
Salt spray off the canals and Great South Bay accelerates galvanic corrosion of step flashing, especially on low-slope 1950s ranch rooflines where water sits longer. Standard galvanized flashing simply doesn’t last here. We specify heavier-gauge stainless or copper flashing for Lindenhurst canal-front homes, and we extend the counter-flashing into the masonry with proper sealant - done right, and we stand behind it.
It starts with a Level 2 camera inspection to verify the terra-cotta liner can handle the heat output of a wood stove - many 1950s Cape Cods in Lindenhurst were built for oil heat and never properly lined for solid fuel. Assuming the liner is sound or has been upgraded, we typically install a stainless insulated cap with integrated spark arrestor and proper clearances, plus verify the crown sheds water away from the chase. For wood-stove-primary homes, we also inspect the connector pipe and thimble condition. Call (516) 614-4632 and we’ll walk through exactly what your setup requires.
