Why Hearthstone Chimney Co. of New York City Is Manhasset’s Preferred Chimney Cap & Crown Company
Manhasset homeowners stay in their houses. The 1920s Colonials, the 1930s Tudors, the estate-style homes built for Gold Coast families - these weren’t starter homes, and the people who own them now aren’t looking for a quick flip. They want the repair done correctly so they don’t think about it again. We’ve earned that trust over 42 years by documenting every inspection with photos the homeowner can see, delivering a plain-English verdict, and backing the work with our 90-Day Done Right Promise in writing.
Our technicians are background-checked, uniformed, and trained on the specific failure patterns of Manhasset’s pre-war housing stock. They know what a corbelled offset looks like, why it matters for cap installation, and how to fabricate a custom multi-flue cap on-site when a standard unit won’t seat properly. Most jobs finish in one visit. The price we quote is the price on the invoice.
When you call (855) 950-3861, you reach a live person - not an app, not a menu, not a promise to call back. That matters when water is pouring through a cracked crown during a January nor’easter.
Our Chimney Cap & Crown Services in Manhasset
Custom Cap Fabrication
Standard caps don’t fit Manhasset’s legacy chimneys. In the 11030 ZIP, many pre-war chimneys have corbelled offsets that trap creosote and block standard cap installations, requiring custom multi-flue caps fabricated on-site by our crew. We measure, cut, and secure Gelco and Copperfield stainless steel to the exact dimensions of your flue termination, accounting for the irregular brick courses and offset courses that are routine here. A custom cap in Manhasset typically runs $480-$720 installed, with single-flue custom work at the lower end and complex multi-flue fabrication at the upper.
Multi-Flue Cap Installation
Homes with two or more fireplaces - common in Manhasset’s larger Colonials and Tudors - need multi-flue caps that protect all flues with a single hooded structure. We recently serviced a 1930s Tudor on Plandome Road where the original coal-converted-to-gas chimney had a deteriorated crown with a missing cap, causing salt-air-driven spalling. We installed a custom multi-flue DuraFlex cap and applied a HeatShield crown coating to seal the cracked lime mortar. Multi-flue installations in Manhasset range from $620-$890 depending on span, height, and whether the crown needs rebuilding first.
Crown Repair
The crown is the concrete or mortar wash that seals the chimney top between the flue tiles and the brick edge. In Manhasset, salt-laden air from Manhasset Bay accelerates spalling of brick under missing or undersized caps, leading to crown failure within 5-7 years - faster than you’ll see in inland Nassau County communities just a few miles south. Crown repair involves removing loose material, forming a proper slope for drainage, and pouring new crown mix with expansion joints around each flue tile. Typical crown repair in Manhasset: $340-$580.
Crown Coating
When the crown is cracked but structurally sound, we apply HeatShield crown coating - a flexible, waterproof membrane that bridges hairline cracks and prevents water infiltration without the cost of full rebuild. This is often the right choice for Manhasset homeowners whose crowns are deteriorating but haven’t yet failed completely. Crown coating runs $280-$420 in Manhasset, and we pair it with cap installation or replacement to address the root cause of the water damage.

Common Chimney Cap & Crown Problems We See in Manhasset Homes
- Salt-air spalling under failed caps. Manhasset borders Manhasset Bay, an inlet of Long Island Sound, meaning chimneys here are exposed to persistent salt-laden air that accelerates spalling of brick faces and erosion of lime-based mortar joints. A missing or poorly fitted cap lets that salt air reach the crown directly, and the freeze-thaw cycle does the rest.
- Oversized flues rotting cap hardware. Because so many Manhasset homes were heated by coal furnaces originally vented into large masonry flues, the flue cross-sections are far too big for the modern gas appliances now sharing or using those same chimneys. Excessive draft and moisture condensation rot cap screens and corrode fasteners, meaning even a “new” cap can fail prematurely if the flue sizing isn’t addressed.
- Corbelled offsets blocking standard caps. The stepped, corbelled construction of 1920s-1940s chimneys creates offsets that prevent standard cap anchoring. We’ve retrieved caps from Manhasset lawns after nor’easters blew them loose - because they were never properly secured to an irregular surface in the first place.
- Crown wash erosion from lime mortar deterioration. Manhasset’s pre-war chimneys were built with lime mortar that was never repointed after coal-to-oil-to-gas conversions. The crown wash, typically poured over that same deteriorated substrate, cracks and crumbles, allowing water to saturate the chimney stack.

FAQs - Chimney Cap & Crown in Manhasset
Many Manhasset chimneys have corbelled offsets, multiple flues of different diameters, or flue tiles that don’t align with modern standard cap dimensions. In the 11030 ZIP, we fabricate custom multi-flue caps on-site for roughly one in three cap installations. Call (855) 950-3861 and we’ll measure your flue termination to determine whether a standard or custom solution is the right fit - estimates are free.
Salt-laden air accelerates spalling of brick faces and erosion of lime-based mortar joints by a faster cycle than inland Nassau County communities experience, typically reducing crown life from 15-20 years to 5-7 years if the cap is missing or poorly fitted. A properly installed cap is the first defense, and crown coating or repair addresses existing damage before it reaches the brick. We can assess your crown’s condition during a Level-2 camera inspection with photos you can see.
Yes. Coal-era flues are oversized for modern gas appliances, creating excessive draft and moisture condensation that rots cap screens and corrodes fasteners. We often pair cap installation with flue liner recommendations to address the root cause, and we size the cap’s screen and hood to the actual appliance output, not the original coal flue dimension. This is a common finding in Manhasset pre-sale inspections.
We remove the failed crown wash, inspect the brick courses beneath for spalling or saturation damage, form a new slope with proper expansion joints around each flue tile, and pour new crown material rated for freeze-thaw exposure. On a typical Manhasset Tudor, this takes 4-6 hours and is completed in one visit. We then install or replace the cap to protect the new crown. Most crown repairs in Manhasset run $340-$580; full rebuilds with custom caps range $780-$1,240.
Yes. Crown coating seals cracks in the crown surface but does not prevent water, debris, or animals from entering the flue. The cap and crown work together: the crown sheds water from the chimney top, and the cap keeps it out of the flue while allowing proper draft. We recommend both, and we warranty the coating as part of our 90-Day Done Right Promise when paired with cap installation. Call (855) 950-3861 for an exact quote.
