Robert Garcia, our owner and lead technician, handles every cap and crown job personally, bringing 17 years of chimney-only experience to homes along Hempstead Turnpike, Conklin Street, and the quieter blocks near Republic Airport. If you’re seeing water stains on your ceiling after a nor’easter, or you’ve noticed crumbling mortar on your chimney top, call us at (866) 884-9512 for a free estimate.

Farmingdale’s housing tells a specific story, and that story affects your chimney directly. The post-war Cape Cods and ranches built for Republic Aviation workers in the late 1940s through early 1960s dominate this market. These homes weren’t built for modern heating appliances, and their chimneys show it. Our Chimney Cap & Crown team has worked on hundreds of these properties, and we’ve developed specific solutions for the failure patterns that repeat across this neighborhood.
Why Apex Chimney Cleaning Greater New York Is Farmingdale’s Preferred Chimney Cap & Crown Company
We’ve earned our reputation in Farmingdale one roof at a time. Over 1,096 verified customer reviews averaging 4.7 stars back up what we do — and a significant portion of those come from Nassau County homeowners who’ve watched Robert Garcia climb their ladder, diagnose the problem, and fix it himself. No dispatched crews, no subcontractors, no wondering who’s actually going to show up.
Our response time to Farmingdale is consistently same-day or next-day during peak season. We know the local traffic patterns — how to avoid the backup on Route 110 near the airport, which side streets save time when Hempstead Turnpike is clogged. That local knowledge translates to faster arrivals and more jobs completed per day, which means we can keep our schedule flexible for emergencies.
What really sets us apart here is our familiarity with Republic Aviation-era construction. We’ve crawled through enough attics in Farmingdale’s 1950s ranches to know that the original clay tile liners are almost always cracked, almost always unlined from that 1980s oil-to-gas conversion, and almost always improperly capped. When Robert inspects your chimney, he’s not guessing — he’s pattern-matching against hundreds of similar jobs.
Our Chimney Cap & Crown Services in Farmingdale
Cap Installation
New cap installation in Farmingdale typically costs $340–$680 for a standard single-flue galvanized or stainless unit, with copper and custom fabricated caps running higher. Most Farmingdale homes we encounter either have no cap at all — original construction omitted them, or they blew off in a storm decades ago — or they’re sporting a big-box store special that’s already rusting through from the salt air. We measure your flue precisely and install caps with proper overhang and screen mesh to keep out the starlings and squirrels that plague South Shore chimneys.
Cap Replacement
When your existing cap is rusted, improperly sized, or missing its screen, replacement is straightforward but critical. In Farmingdale’s coastal environment, we see standard caps corrode through in 5–7 years instead of the 15–20 you’d expect inland. We stock replacement caps sized for the common flue dimensions found in local Cape Cods and split-levels, and we carry stainless hardware that won’t seize or snap when the next tech needs to remove it. A typical replacement runs $280–$520 installed.
Crown Repair
Crown repair addresses the concrete or mortar wash that seals the top of your chimney between the flue tiles and the brick edge. In Farmingdale, this is where we find the most urgent problems. Sitting on the flat Hempstead Plain with no topographic wind breaks, Farmingdale chimneys catch nor’easter winds full-force. The freeze-thaw cycle — water penetrates cracked crown mortar, expands when frozen, spalls off chunks of concrete — destroys crowns faster here than in inland Nassau towns like Mineola or Garden City. Crown repair involves grinding out deteriorated material and repouring with proper slope and overhang, typically $520–$940.
Crown Coating
For crowns with minor cracking but sound structure, we apply HeatShield crown coating — a specialized refractory compound that creates a seamless, waterproof membrane. This is often the right call for Farmingdale’s 1950s chimneys where the crown is structurally intact but the surface is porous or spider-webbed with hairline cracks. The coating fills existing fissures and prevents new water penetration, extending service life 10–15 years at roughly $380–$620. We used this exact solution on that 1954 Cape Cod on High Street near Republic Airport — ground out the failed mortar, applied the HeatShield coating for a seamless seal, and the result outlasted any mortar-only repair would have.
Multi-Flue Cap
Multi-flue caps are essential for many Farmingdale split-levels and larger Cape Cods that vent multiple appliances through a single chimney structure. These custom-fabricated units cover the entire chimney top, eliminating the gaps between individual caps where water and wildlife enter. Given Farmingdale’s common scenario — original 1950s construction with two or three clay flue tiles, often cracked, serving appliances they were never designed for — a multi-flue cap provides comprehensive protection. We fabricate these to your chimney’s exact dimensions, with proper clearances for each flue, starting around $680–$1,200 depending on size and material.
Custom Cap
When standard sizes won’t work — oversized flues, unusual chimney dimensions, or aesthetic requirements for historic properties — we fabricate custom caps using copper, stainless steel, or powder-coated aluminum. We’ve built custom caps for Farmingdale homeowners who wanted copper to match period architectural details, and for others whose chimney configurations simply defy catalog solutions. Custom work starts at $820 and scales with complexity and material choice.

Trusted Brands We Service in Farmingdale
We install professional-grade materials from Famco, Olympia Chimney, and Copperfield — the same product lines commercial contractors specify for coastal installations. These aren’t retail-grade items; they’re built with heavier gauge metal, better welds, and hardware that withstands salt-air corrosion. We maintain stock of common cap sizes and fastener kits at our facility, which means most Farmingdale jobs don’t wait on parts. When we need something custom or specific, our supplier relationships get it here fast. The difference shows up years later — our caps don’t rattle loose in the first winter storm, and the stainless hardware comes apart cleanly when it’s time for your next inspection.
Common Chimney Cap & Crown Problems We See in Farmingdale Homes
- Salt-laden nor’easter winds accelerate crown mortar spalling on Hempstead Plain houses with no wind breaks, exposing the flue tile top to direct rain intrusion. We see this on nearly every 1950s ranch in the 11735 ZIP — the crown mortar is soft enough to dig with a fingernail, and the freeze-thaw cycle turns small cracks into major gaps within a few seasons.
- Cracked clay tile liners from original 1950s construction allow flue-gas bypass into the crown cavity, causing hidden corrosion on cap fasteners and accelerated deterioration of any remaining mortar. This is the problem most Farmingdale homeowners don’t know they have until we run a camera inspection — the oil-to-gas conversions of the 1980s and 1990s were completed without the code-required stainless reliner, leaving those cracked tile joints as a pathway for exhaust gases.
- Missing or undersized caps on multi-flue chimneys — common in Farmingdale split-levels — let rain and nesting birds block the flue, trapping moisture against deteriorating crown mortar. We’ve pulled enough starling nests and squirrel caches from these chimneys to know that an unprotected flue becomes a wildlife highway within a year or two.
- Original terra-cotta crowns completely spalled from decades of freeze-thaw exposure, leaving cracks wide enough to see daylight from the firebox below. On that 1954 Cape Cod on High Street near Republic Airport, we found exactly this — the crown was structurally failed, the gas insert was venting into a 70-year-old tile joint, and the homeowner had no idea until water started dripping through the ceiling.
Pricing for Chimney Cap & Crown in Farmingdale, NY
Here’s what chimney cap and crown work actually costs in the Farmingdale market:
| Service | Typical Range |
|---|---|
| Standard cap installation (single flue, galvanized/stainless) | $340 – $680 |
| Cap replacement | $280 – $520 |
| Crown repair (grind and repour) | $520 – $940 |

What moves you within these ranges? Material choice is the big one — copper costs more than galvanized steel, and for good reason on a coastal chimney. Accessibility matters too; steep roofs or tight property lines add time and safety equipment. The condition of your existing crown affects whether we can cap over it or need to rebuild first. And if we find that your 1950s clay liner is cracked — statistically likely in Farmingdale — we may recommend addressing that before or alongside cap work. Every estimate we provide is free, detailed, and specific to your chimney. No ranges given over the phone without seeing it first — that’s how mistakes happen. Call (866) 884-9512 to schedule.

FAQs — Chimney Cap & Crown in Farmingdale
Farmingdale’s position on the flat Hempstead Plain exposes chimneys to unblocked nor’easter winds carrying salt-laden moisture from the Atlantic, while inland towns like Mineola or Garden City get some topographic buffering. The freeze-thaw cycle here is more aggressive, and the salt accelerates mortar erosion even between freeze events. Crown coating or proper rebuild with modern materials is essential for longevity here — standard mortar repairs that last 15 years inland may fail in 7–10 years on a Farmingdale roof. Call (866) 884-9512 and we’ll assess whether your crown needs coating now or can wait.
Yes — if your 1950s ranch has two or more flue tiles emerging from a single chimney structure, a multi-flue cap is the correct solution. Individual caps leave gaps between them where water and wildlife enter, and they don’t protect the crown surface between flues. In Farmingdale’s housing stock, we frequently find that the space between flue tiles has become a water collection point, accelerating the very crown deterioration that exposes your liner. A custom-fabricated multi-flue cap covers the entire chimney top, channels water away, and eliminates those entry points. Call (866) 884-9512 for a free measurement and quote.
Probably — and you likely need a liner inspection too. The 1980s–90s oil-to-gas conversions in Farmingdale were frequently completed without the code-required stainless steel reliner, leaving original clay tiles to handle cooler, more corrosive gas exhaust. Those tiles crack. Exhaust seeps into the crown cavity. The crown mortar deteriorates from the inside out. Even if your crown looks intact from the ground, camera inspection often reveals hidden damage. We assess crown condition and liner integrity together — they’re interdependent systems. Call (866) 884-9512 for a full evaluation.
Absolutely — we fabricate and install copper caps regularly on Farmingdale’s 1950s Cape Cods, both for durability and architectural compatibility. Copper develops a protective patina that handles salt air better than galvanized steel, and it suits the period aesthetic of these homes. We measure on-site, fabricate to your chimney’s exact dimensions, and install with stainless fasteners that won’t corrode and seize. Lead time is typically 2–3 weeks for custom copper fabrication. Call (866) 884-9512 to discuss options and get an exact quote.
Annually — and we mean that literally for Farmingdale’s coastal environment. The combination of salt air, aggressive freeze-thaw, and aging 1950s construction means cap and crown condition can deteriorate significantly in a single season. We recommend scheduling inspection each spring, after the worst of the nor’easter season has passed, so any winter damage gets addressed before the next heating season. During inspection, we check cap integrity, crown condition, fastener corrosion, and liner status — the full picture. Call (866) 884-9512 to book your annual inspection; estimates are always free.
