Why Premier Chimney Cleaning Connecticut Is New Cassel’s Preferred Chimney Cap & Crown Company
New Cassel homeowners aren’t looking for a handyman who “also does chimneys.” They’re looking for someone who understands why their 1958 Cape on Park Avenue keeps leaking even after the last guy put on a new cap. That’s where we come in.
Eight years, one specialty. Anthony Perez leads every job personally — not a subcontractor, not a seasonal hire. When you call, you get the person whose name is on the business and whose reputation is tied to every brick we touch.
800+ homeowners have reviewed us, and we carry a 4.7-star average across those jobs. That volume matters — it means we’ve seen the exact failure patterns that repeat across New Cassel’s housing stock. We know which blocks have the original 1950s clay liners that separate at the joints. We know which streets still have the galvanized crowns that rust through at the flue tile seam.
From our Bridgeport base, we’re typically at your New Cassel door within 45 minutes to an hour for scheduled work. Emergency calls — water pouring through the chimney breast, a cap torn off in a storm — we prioritize same-day.
Our Chimney Cap & Crown Services in New Cassel
Cap Installation
New Cassel’s original masonry chimneys were built with single-flue openings and no caps at all — or with homemade wire-mesh covers that rusted away decades ago. We install properly sized Gelco and Famco caps with correct overhang and mesh screening that keeps out rain, squirrels, and the starlings that nest in flues along Prospect Avenue every spring. A standard single-flue cap install in New Cassel runs $280–$450, including proper measurement and storm-proof attachment.
Cap Replacement
We replace more caps in New Cassel than we install fresh. The reason is simple: homeowners buy a hardware-store cap that doesn’t fit their flue tile dimensions, or a cheap galvanized unit that rusts through in three years of Long Island coastal air. We measure your flue tile precisely and match material to your conditions — stainless steel for most New Cassel applications, copper where the homeowner wants longevity and doesn’t mind the patina. Cap replacement typically runs $320–$580.
Crown Repair
The concrete crown is the chimney’s roof. In New Cassel’s post-war Capes, these crowns were often poured too thin — two inches instead of the recommended four — with no overhang beyond the brick face. Freeze-thaw cycles open cracks; water gets in; the crown separates from the brick. We cut out failed sections, repour with proper slope and drip edge, or apply full rebuilds where the crown has disintegrated. Crown repair in New Cassel ranges from $450 for crack sealing and resurfacing to $1,200 for complete removal and repour.
Crown Coating
This is where our HeatShield work gets specific to New Cassel’s conditions. We apply HeatShield crown coating to structurally sound but weathered crowns — the ones with hairline cracking and surface spalling but no through-cracks or separation from the brick. The coating forms a flexible, waterproof membrane that bridges minor cracks and sheds water. It’s not a fix for a failed crown, but it’s the right call for a 1970s crown that’s starting to show its age. Crown coating runs $380–$650 depending on chimney footprint.
Multi-Flue Cap
Here’s a New Cassel-specific scenario we see constantly: a Cape Cod converted to a duplex with two fireplaces sharing one chimney stack, but only one flue liner installed. The homeowner puts a single-flue cap on the active flue and leaves the other open. Rain goes straight down the unlined flue, saturating the party wall. We fabricate and install custom multi-flue caps that cover the entire chimney top, with screened risers sized to each flue opening. Multi-flue caps start around $680 for standard configurations, custom work runs higher.

Custom Cap
Some New Cassel chimneys don’t fit catalog parts — oversized flue tiles, irregular chimney tops, or historic details the homeowner wants preserved. We measure, fabricate, and install custom caps from Copperfield and Olympia Chimney materials, typically in stainless or copper. Custom cap work starts at $750 and scales with complexity and material choice.

Common Chimney Cap & Crown Problems We See in New Cassel Homes
- Lime-mortar liner joints failing beneath the crown. In New Cassel’s post-war Capes, the original clay tile liners were set with lime mortar that degrades faster than modern refractory cement. The joints separate under thermal cycling, and moisture that should be shed by the crown instead gets pulled into the gap, eroding the crown from below and staining interior walls.
- Original copper or galvanized crowns corroding at the flue tile seam. That 1950s crown looked good for decades, but galvanic corrosion where dissimilar metals meet — or simple rust on galvanized steel — opens gaps that admit rain directly onto the brick face. We see this on Babylon Turnpike and the surrounding blocks regularly.
- Single-flue caps on multi-flue chimneys leaving unused flues exposed. Duplex conversions are common in New Cassel’s dense housing stock. A cap on one flue doesn’t protect the other. Birds nest. Rain enters. The unlined flue becomes a conduit for moisture into the building envelope.
- Crown poured without proper slope or overhang. The original builder flat-poured the crown or stopped it flush with the brick. Water pools. Freeze-thaw opens cracks. Spalling follows. By the time the homeowner notices interior damage, the crown is structurally compromised.

What moves you within these ranges? Crown size and accessibility — a walkable low roof on a one-story Cape costs less than scaffolding a two-story colonial. Material choice — copper costs more than stainless, though both outlast galvanized. And whether we discover underlying liner damage once we’re on the roof. That last point is especially relevant in New Cassel, where the original lime-mortar flue systems are reaching end of life. We always inspect the flue tile condition before quoting cap or crown work; installing a perfect cap over a separating liner is wasted money.

FAQs — Chimney Cap & Crown in New Cassel
The cap isn’t the problem — it’s the lime mortar that originally set your flue tiles. In New Cassel’s post-war construction, builders used lime mortar that degrades faster than modern refractory cement under thermal cycling. The tiles separate at the joints, moisture enters the gap, and the freeze-thaw cycle continues the damage regardless of how good your cap is. We assess liner condition before any cap installation; if the tiles are separating, we recommend liner repair or replacement alongside the cap work. Call (833) 719-7193 and we’ll inspect both — estimates are free.
Yes — if your chimney has two flue openings, you need coverage over both regardless of how many are actively lined. An open flue is a direct path for rain and animals into your chimney structure. In New Cassel’s duplex conversions, we regularly find one flue abandoned and uncapped, with water damage accumulating in the party wall for years. A custom multi-flue cap from our DuraFlex line seals the entire chimney top. We’ll measure your configuration and quote exact — call for a free estimate.
No. Crown coating — we use HeatShield — is formulated for the concrete crown surface only. It waterproofs and protects sound crown material, but it cannot bridge separated flue tiles or restore liner integrity. If your clay tile liner is cracked or joint-separated, that requires liner repair, relining with a stainless system, or full liner replacement depending on severity. We evaluate both crown and liner condition on every New Cassel roof we climb. Call (833) 719-7193 for an inspection that addresses the actual problem.
The cap may be shedding water from above, but if your crown is cracked or your flue liner joints are separated, moisture is entering from within the chimney structure and migrating outward through the brick. This is common in New Cassel’s 60-plus-year-old chimneys where multiple failure points coexist. We see this pattern on original Capes from the 11590 core — the homeowner fixes the obvious problem (missing cap) while the hidden pathway (crown cracks, liner gaps) continues saturating the brick. Our inspection checks the full system: cap, crown, liner, and brick condition. Call for a complete assessment.
Stainless steel or copper — never galvanized. Long Island’s maritime air accelerates rust on galvanized and powder-coated steel; we’ve replaced three-year-old galvanized caps that looked fine from the ground but were rusted through at the flue tile seam. We install Gelco and Famco stainless caps as our standard, and offer Copperfield copper for homeowners who want maximum longevity. Both materials handle New Cassel’s humidity and freeze-thaw cycles without corrosion. We’ll show you samples and price both options when we quote — call (833) 719-7193.
