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.

Our Chimney Cap & Crown Services in Melville
Cap Installation
New cap installation in Melville runs $280-$520 for a standard single-flue stainless unit, with multi-flue caps starting around $450. We size for your flue and your exposure - and in Melville, that means specifying stainless over galvanized. The salt-laden Sound air, even at five miles inland, pits galvanized caps at the seams and skirt within seasons, not decades. We install caps from Gelco and Olympia Chimney, brands that hold up to Suffolk County’s coastal weather. Every installation includes a Level-2 inspection to check what’s below the cap before we seal it.

Cap Replacement
Cap replacement is our most common call in Melville. The original builder-grade caps on 1960s-1980s homes here are often Famco-style galvanized units that have rusted through at the seams after twenty-plus years of salt and freeze-thaw. Replacement typically costs $340-$620. We remove the corroded unit, inspect the flue opening for spalling brick or eroded mortar, and install a stainless replacement sized to your flue. If your home had an oil-to-gas conversion - extremely common in Melville’s aging stock - we also check whether your oversized clay flue is etching from acidic condensate. That interior damage isn’t visible from the roof, which is why our Chimney Cap & Crown team includes a camera inspection with every cap job.

Crown Repair
Crown repair in Melville addresses the concrete or mortar wash that seals the chimney top between the flue tile and the brick edge. A cracked crown lets nor’easter rain run directly into the smoke chamber and firebox, and in Melville’s climate, freeze-thaw cycling turns hairline cracks into spalled channels within a season or two. Repair costs $380-$650 depending on whether we’re patching localized cracks or rebuilding the full crown perimeter. We use professional-grade crown mixes, not bagged concrete from the hardware store. The crown is your chimney’s umbrella - when it fails, everything below it is at risk.

Crown Coating
Crown coating is a flexible membrane application that bridges hairline cracks and seals weathered mortar - a cost-effective alternative to full crown rebuild when the underlying structure is sound. In Melville, we recommend crown coating at $320-$480 for crowns showing early spalling but no structural separation. The coating flexes with freeze-thaw movement rather than cracking again, and it’s particularly effective on the builder-grade clay crowns common to Melville’s postwar stock. We use HeatShield crown coating products, applied to manufacturer specification. Not every crown qualifies - if the crown has dropped, separated from the brick, or shows through-cracking, we recommend repair or rebuild instead. We’ll show you the photos and explain which category yours falls into.

Multi-Flue Cap
Larger Melville homes - common in the hamlet’s more affluent sections - frequently have multi-flue chimney stacks serving both a fireplace and a furnace or water heater. These require multi-flue caps that cover the entire chimney top, not just individual flue extensions. Multi-flue cap installation in Melville runs $520-$890 depending on chimney dimensions and cap material. We measure on site, fabricate from stainless, and ensure proper clearance for each flue’s draft. The multi-flue design also reduces the exposed crown area, which helps in Melville’s salt-air environment by limiting the mortar surface directly exposed to weather.

Custom Cap
For non-standard flue configurations or heritage chimneys, we fabricate custom caps to specification. Custom work in Melville starts around $680 and is priced after measurement. We’ve built custom solutions for oversized flues, offset twin flues, and chimneys with irregular crown profiles - common in additions and renovations across Melville’s decades of residential growth.

Trusted Brands We Service in Melville
We work exclusively with professional-grade materials - no builder-grade substitutes. For cap and crown work in Melville, we stock and install Gelco and Olympia Chimney stainless caps, HeatShield crown coating and repair products, and Famco hardware where original equipment needs matching. These brands are specified for coastal exposure and carry the warranties that matter when you’re five miles from salt air.

For relining work flagged during cap or crown inspection, we carry DuraFlex and Copperfield liner materials - the same professional-grade products we’d use on our own homes.
Common Chimney Cap & Crown Problems We See in Melville Homes
- Galvanized caps rusted through at the seams. The salt-laden Sound air pitts galvanized cap skirts and seams faster than in truly inland Suffolk towns. We regularly remove original caps on Melville’s 1960s-1980s homes that look intact from the ground but are perforated at the flange. Wind-blown rain enters through these gaps and runs down the flue liner, saturating the smoke chamber below.
- Freeze-thaw crown cracking on builder-grade clay crowns. Melville’s original crowns were often a thin mortar wash over clay tile, not structural concrete. After forty to sixty winters of freeze-thaw, these crowns spall and crack, opening channels that feed water directly into the chimney structure. We find this on colonials off Old Country Road and split-levels throughout the hamlet.
- Oversized clay flues etching from gas condensate. Decades of oil-to-gas conversions left many Melville homes running modern gas appliances through flues originally sized and glazed for oil combustion. The low-temperature exhaust condenses inside the oversized liner, etching tile with acidic moisture. This interior damage corrodes cap hardware from the inside out and can pit stainless if the condensate reaches the cap base - a problem generic sweeps often miss because they don’t camera the flue during a cap call.
- Multi-flue chimneys with missing or undersized caps. Melville’s larger homes frequently have two or three flues in a single stack, but only the fireplace flue may have a cap while mechanical flues vent open to weather. This exposes the crown center to direct rain and accelerates mortar erosion across the full chimney top.

FAQs - Chimney Cap & Crown in Melville
We recommend annual inspection in Melville, versus every 18-24 months for truly inland Suffolk towns like Commack or Dix Hills. The salt-laden Sound air, even at Melville’s mid-island distance, accelerates cap corrosion and crown spalling measurably. That shorter interval lets us catch crown hairline cracks before freeze-thaw opens them to full channels, and spot galvanized cap rust before it perforates. Call (934) 348-4832 to schedule - estimates are free.
On homes built in the 1960s-1980s, the crown usually fails first, but the cap gets the blame. The original builder-grade clay crown cracks and spalls, opening gaps that let water reach the flue. Homeowners notice water in the firebox and assume the cap is leaking, but the real problem is often the crown beneath it. We inspect both before recommending a fix - no point in a new cap if the crown is channeling water underneath it. Call (934) 348-4832 and we’ll show you exactly what we found on camera.
Decades of oil-to-gas conversions left oversized flues throughout Melville’s housing stock. Oil combustion required larger, hotter flues; gas exhaust is cooler and more acidic. The resulting condensate etches clay tile from within and can corrode cap hardware from the inside out. This doesn’t change the cap or crown installation itself, but it means every cap or crown job we do in Melville includes a camera inspection of the flue interior. If the liner is acid-pitted, we flag Gelco relining before capping - otherwise you’re sealing a deteriorating system. Call (934) 348-4832 for an inspection that checks the full stack, not just the roofline.
Yes. A multi-flue chimney needs a cap that covers the entire chimney top with screened outlets for each flue, not individual caps stacked side by side. This is common in Melville’s larger homes where one stack serves a fireplace and a furnace or water heater. Multi-flue caps run $520-$890 installed, protect more of the crown from direct weather exposure, and prevent cross-drafting between flues. We measure on site and fabricate to your chimney’s exact dimensions.
Crown coating works when the crown is structurally intact - no separation from the brick edge, no through-cracks, no dropped or hollow sections. Good candidates show surface spalling, hairline cracking, or weathered mortar but still shed water in a light rain. If you see pieces of the crown missing, gaps between crown and brick, or water staining on the chimney breast inside, you likely need repair or rebuild instead. We’ll photograph the crown during inspection and explain which category yours falls into. Call (934) 348-4832 for a free evaluation - no obligation, no pressure.
