Fast, Reliable Chimney Cap & Crown Across Melville
Chimney cap and crown repair in Melville typically runs $280–$850 depending on whether you’re sealing a single crown or installing a multi-flue cap system, and most jobs are completed in one visit. We’re familiar with the specific challenges these 1960s–1980s colonials and split-levels present — original clay-tile-lined chimneys, abandoned oil flues, and crowns that have taken a beating from Long Island’s coastal freeze-thaw cycles. Gary Murphy and our Chimney Cap & Crown team make the drive from Bridgeport to Melville regularly, and we know the difference between a quick cap swap on a Route 110 corridor home and a full crown rebuild on a Sweet Hollow colonial with two flues and a conversion history. Call (888) 975-6389 for a free estimate — we’ll give you an honest assessment of what your chimney actually needs.
Why Sterling Chimney Cleaning Bridgeport Is Melville’s Preferred Chimney Cap & Crown Company
More than 1,200 homeowners have trusted us with their chimneys, and that 4.7-star average across 1,234 verified reviews reflects the accountability that comes from owner-operated work. Gary Murphy handles every cap and crown job personally — he’s the one climbing the ladder, not a subcontractor you’ve never met.
We’ve built repeat business throughout Suffolk County over 14 years, one trade. That means when we pull up to a Melville home, we’re already thinking about what we’ll find: the oversized oil-burner flue that should’ve been capped after the gas conversion, the spalled crown from last winter’s nor’easter, the multi-flue setup that needs a custom solution rather than a big-box store universal cap.
Our response time to Melville is typically same-day or next-day for crown emergencies — water pouring into a flue doesn’t wait, and neither do we. We carry DuraFlex and Gelco multi-flue caps on the truck, plus HeatShield crown coating materials, so most Melville jobs don’t require a second trip.
Our Chimney Cap & Crown Services in Melville
Cap Installation
New cap installation in Melville starts around $280 for a standard single-flue galvanized or stainless unit, but most of the homes we service here need more. The larger executive colonials near West Hills and Dix Hills frequently have two- or three-flue chimney systems serving both the fireplace and mechanical equipment. We install DuraFlex and Olympia Chimney multi-flue caps sized precisely for these setups — not the adjustable universal caps that gap and leak. For a 1970s split-level on Bagatelle Road with an abandoned oil flue and an active fireplace flue, a custom multi-flue cap is the only way to seal both properly without creating a new moisture path.
Cap Replacement
Cap replacement is our most common Melville call, and there’s a reason. The original caps on these 40–50-year-old chimneys were often thin galvanized steel that rusted through years ago, or they were never installed at all on secondary flues. We see this constantly on homes that converted from oil to gas — the oil-burner flue gets abandoned, nobody caps it, and suddenly squirrels are nesting in the flue or rain is degrading the crown below. A replacement cap in Melville runs $280–$450 for standard single-flue stainless, or $480–$720 for multi-flue systems. We remove the old unit, inspect the crown condition underneath, and install a properly fitted cap that accounts for your flue configuration today, not what it was in 1975.
Crown Repair
Crown repair in Melville addresses the concrete wash that seals the chimney top between the flue tiles and the brick edge. On a recent job in the Sweet Hollow area of Melville, we serviced a 1970s colonial with a two-flue chimney where the original oil-burner flue had been abandoned after a gas conversion. The crown had spalled from freeze-thaw cycles, and we installed a custom multi-flue cap from DuraFlex to seal both flues and prevent further moisture intrusion, ensuring the homeowner’s system was safe for their new gas insert. Crown repair typically costs $450–$680 for partial rebuilds, or $720–$950 for full crown replacement on larger multi-flue chimneys. The freeze-thaw cycling here — moisture from Long Island Sound and the Atlantic hitting that concrete, expanding, contracting — destroys crowns faster than inland climates. We use professional-grade concrete mixes formulated for chimney exposure, not bagged hardware-store patch.
Crown Coating
Crown coating is preventive maintenance that saves Melville homeowners from full rebuilds. At $380–$550, we apply HeatShield or Gelco flexible crown sealant over sound but weathered concrete, creating a waterproof membrane that bridges hairline cracks and stops water penetration. This is particularly valuable on multi-flue crowns where the concrete surface area is larger and more vulnerable to pooling. We recommend crown coating every 8–12 years in Melville’s climate — sooner if you can see cracking or if your chimney sits exposed to prevailing winds. It’s a fraction of rebuild cost, and we can apply it during the same visit as your annual sweep.
Multi-Flue Cap
Multi-flue caps are essential for Melville’s larger homes. These custom-fabricated covers span the entire chimney top, protecting multiple flues and the crown surface between them. Starting at $620 and ranging to $1,100 for complex configurations, they’re fabricated from stainless or copper to exact dimensions. We measure on-site, account for flue spacing and height variations, and install with proper clearances for draft performance. For homes with both an active fireplace flue and an abandoned or converted mechanical flue, a multi-flue cap is the cleanest solution — one unit, zero gaps, no animal entry points.
Custom Cap
Custom caps address unusual flue sizes, historic masonry profiles, or specific aesthetic requirements. In Melville’s 11747 ZIP, we’ve fabricated custom solutions for oversized flues left from commercial-grade oil burners, decorative copper caps for visible chimney exposures, and specialty configurations where standard catalog items simply don’t fit. Pricing starts around $750 and depends on material and complexity. Gary measures, specifies, and installs — no middlemen, no miscommunication.

Trusted Brands We Service in Melville
We install DuraFlex, HeatShield, and Gelco — the materials professionals specify, not brands pulled off a retail shelf. DuraFlex multi-flue caps are our go-to for Melville’s two- and three-flue chimneys; their stainless construction handles salt-laden coastal air without the corrosion we see on lesser products. HeatShield crown coating gives us a monolithic seal that flexes with thermal expansion, critical given the temperature swings these chimneys see between summer shutdown and winter firing. We stock common sizes and configurations locally, so most Melville cap and crown jobs don’t wait on shipping. When you need a part we don’t carry, our distributor relationships mean 24–48 hour turnaround — not the two-week delays common with generalist contractors who don’t prioritize chimney work.
Common Chimney Cap & Crown Problems We See in Melville Homes
- Clay-tile liners spalling from freeze-thaw cycling. The original flue tiles in these 1960s–1980s chimneys crack and flake, sending debris onto the smoke shelf and creating pathways for combustion gases. The cracking propagates upward, undermining the crown’s structural support and allowing water to enter the flue system directly.
- Oversized oil-burner flues left abandoned after gas conversion. These unlined-for-gas, uncapped flues are a liability we now expect as a near-standard finding in 11747. Without proper capping, they become conduits for rain, animal entry, and conditioned air loss — and the moisture accelerates crown deterioration on the active flue beside it.
- Poorly sealed crowns accelerating mortar joint deterioration. Melville’s humid shoulder seasons promote internal condensation, and uncoated crown concrete absorbs that moisture. When winter hits, the freeze-thaw cycle pops the surface, opens joints, and soon you’re looking at brick spalling and liner exposure — especially on multi-flue setups where the crown area is largest.
- Universal caps improperly fitted to multi-flue chimneys. Homeowners or handymen install adjustable caps that don’t seat square, leaving gaps for water and wildlife. We remove these constantly on Melville homes and replace with properly sized, flue-specific or full-coverage solutions.

What moves you within these ranges? Crown size and accessibility are the big ones — a two-flue crown on a single-story ranch is straightforward; a three-flue crown on a two-story colonial with a steep roof pitch takes more time and safety setup. Material choice matters too: galvanized caps cost less upfront but need replacement sooner in coastal air; stainless or copper last decades. The condition we find underneath often reveals additional needs — a cap swap becomes a crown repair when we expose saturated, cracked concrete. We quote upfront after inspection, not after surprise discoveries. Estimates are free, and we’ll show you exactly what we’re seeing with camera inspection footage when accessible. Call (888) 975-6389 to schedule.

FAQs — Chimney Cap & Crown in Melville
The freeze-thaw cycling in Suffolk County — moisture from Long Island Sound and the Atlantic hitting concrete crowns, expanding when frozen, contracting when thawed — destroys unprotected concrete in 10–15 years. Melville’s 1970s chimneys have crowns that were never coated with modern flexible sealants, and the original concrete formulations were less resistant to salt-laden coastal air. Crown coating bridges hairline cracks before they become spalls, and at $380–$550, it’s roughly half the cost of a partial rebuild. Call (888) 975-6389 to inspect your crown’s condition — estimates are free.
Yes, absolutely. An uncapped abandoned flue is an open hole in your roof assembly that admits rain, animals, and cold air while accelerating deterioration of the adjacent active flue’s crown. In Melville, where oil-to-gas conversions are widespread, we find these uncapped flues on roughly half the homes we visit in the 11747 ZIP. A proper cap — or better, a multi-flue cap covering both flues — prevents moisture intrusion that leads to liner damage and crown failure. We can evaluate your specific configuration and quote a solution during a single visit. Call (888) 975-6389 to schedule.
A quality stainless or copper cap lasts 15–25 years in Melville’s climate; galvanized caps often fail in 5–8 years due to coastal corrosion. We inspect cap condition during every sweep and will tell you honestly whether you’re good for another season or looking at rust-through. The bigger issue we see isn’t age — it’s improper original installation, with gaps, wrong sizing, or missing storm collars that caused premature failure. If your cap is more than 10 years old or was installed by a non-specialist, it’s worth having Gary take a look. Call (888) 975-6389 for a free evaluation.
304 or 316 stainless steel is our standard recommendation for Melville multi-flue caps — it withstands coastal salt air, sheds snow and ice loads from nor’easters, and doesn’t require the maintenance of painted or galvanized alternatives. Copper is available for visible architectural applications and develops a protective patina, but at a higher initial cost. We specify DuraFlex and Olympia Chimney stainless units with welded seams and proper mesh screening — not the pop-riveted, thin-gauge products that fail at the joints. The right cap for your chimney depends on flue count, exposure, and your long-term plans for the home. Call (888) 975-6389 and we’ll measure, specify, and quote.
Usually not, and here’s why: water already inside a cracked crown freezes and expands with every cold snap, turning a $450 coating job into a $900 rebuild by March. Melville’s winter temperature swings — above freezing during the day, below at night — are particularly destructive to saturated concrete. If you’re actively using the fireplace, combustion moisture adds to the freeze-thaw load. We work through winter weather for urgent crown repairs, and we’ll tarp and seal temporarily if conditions truly prevent immediate work. The inspection to determine urgency is free — call (888) 975-6389 and we’ll get you on the schedule.
