We’ve been driving the winding roads of Route 32 and the back routes off the Catskill Scenic Trail to reach Greenville chimneys for decades. Our Chimney Cap & Crown in Greenville crews know the difference between a year-round farmhouse near the hamlet center and a seasonal place tucked up toward Windham Mountain that sits empty from Memorial Day to November. That distinction matters when we’re diagnosing why your cap failed or your crown cracked. Dispatch and scheduling are coordinated from our New York City office, but the trucks that roll to Greenville carry the same professional-grade materials - Gelco, Olympia Chimney, Famco, and Copperfield - we’ve used on every job since 1984.

Why Hearthstone Chimney Co. Is Greenville’s Preferred Chimney Cap & Crown Company

Greenville homeowners don’t call us because we’re the cheapest. They call because their neighbor had a chain sweep recommend a $4,000 reline for “safety” and couldn’t show a single photo of the damage. We document every flue with a camera you watch in real time, then give you a plain-English verdict on whether you need Chimney Repair - Greenville or just a sweep. No photo, no recommendation. That’s the Keystone Standard we’ve held for over 42 years.

Our technicians are background-checked, uniformed, and trained to complete most cap and crown jobs in one visit. The number on your estimate is the number on your invoice - no-hassle upfront pricing, no surprises on the bill. Calls are answered by a live person 24 hours a day, 7 days a week, not a callback queue. If something isn’t right, we come back. In writing, no arguing.

Russell Haines built this company on the K.E.Y.S. code: Krafted right, Every time, Your home first, Standing behind it. That hasn’t changed since 1984, and it won’t change when your cap needs attention ten winters from now.

Our Chimney Cap & Crown Services in Greenville

Cap Installation

A proper cap is the simplest protection your flue has against Greenville’s mountain weather, and it’s part of our Fireplace Services in Greenville. Without one, rain and snow enter directly, and the freeze-thaw cycles that hit harder here than down on the Hudson Valley floor will split a clay flue tile in two seasons. We install stainless caps from Gelco and Olympia Chimney sized exactly to your flue - not the builder-grade universal caps that blow off in the first March wind. For Greenville’s seasonal homes, we also verify the spark arrestor mesh is intact before you lock up for summer; squirrels don’t hibernate, and an unprotected flue is an invitation.

Cap Replacement

Most cap replacements we do in Greenville aren’t from normal wear. They’re from caps that were never right to begin with - wrong gauge metal, wrong fit, or no storm collar where the flue meets the crown. We remove the failed unit, inspect the flue tile and crown surface beneath it with our camera, then install a replacement that matches your actual flue dimensions. If the crown beneath is cracked, we’ll tell you before we bolt anything down. Photos you can see, a plain-English verdict.

Crown Repair

The crown is the concrete or mortar wash that seals the top of your chimney between the flue tiles and the brick edge. In Greenville’s Catskill foothill climate, crowns take a beating. More freeze-thaw cycles than the valley below. Higher moisture load from mountain snow. We’ve seen crowns less than five years old spiderwebbed with cracks because the original mix had no reinforcing fibers and no proper overhang to shed water. Our Chimney Cap & Crown team repairs crowns with HeatShield crown coat or full rebuilds using professional-grade mixes - never the bagged quick-patch you’ll find at the hardware store. The repair is photographed, explained, and backed by our 90-Day Done Right Promise.

Crown Coating

For crowns with early-stage cracking but sound structural integrity, a flexible crown coating from HeatShield can add years of life. This isn’t paint. It’s a formulated membrane that bridges hairline cracks and sheds water while allowing the crown to breathe. We apply it only after pressure-washing the surface and inspecting with the camera for deeper fractures. In Greenville, where many chimneys sit dormant through the wettest months, a crown coating applied in late summer can prevent the accelerated deterioration that hits when that first heavy freeze arrives in November.

Multi-Flue Cap

Greenville’s older farmhouses and fieldstone colonials often have multi-flue chimneys serving a fireplace, a wood stove, and maybe an old oil furnace - all venting through one broad stack. A single cap stretched across all flues rarely seals properly. The flues are different heights. The flashing meets the crown at uneven angles. Water runs in at the cap edge, not the crown, and the homeowner thinks the crown is the problem. We measure each flue independently and install multi-flue caps from Gelco and Olympia Chimney with proper height differentials and integrated storm collars. Done right - and we stand behind it.

Custom Cap

Some Greenville chimneys need what no catalog carries. Oversized fieldstone tops. Irregular flue spacing. Historical preservation requirements. We fabricate custom caps in copper and stainless steel, measured on-site, built to fit. Russell Haines reviews every custom order personally. The cap arrives, the tech installs it, and you get the same 90-Day Done Right Promise that covers every standard part we sell.

Trusted Brands We Service in Greenville

We don’t substitute. Every cap, crown coat, and custom fabrication we install in Greenville comes from professional-grade suppliers: Gelco for stainless multi-flue caps, Olympia Chimney for flue-specific sizing and storm collars, and Famco for custom copper and specialty flashing. We stock the common Greenville sizes on our trucks - the 8×13 and 13×13 flue tiles we see in the area’s 19th-century farmhouses - so most installations don’t wait on a parts order. When a custom cap is needed, we measure, fabricate, and return. No shortcuts, no builder-grade substitutes.

Common Chimney Cap & Crown Problems We See in Greenville Homes

• Crown cracking from Catskill freeze-thaw cycles. Greenville’s foothill position brings more annual freeze-thaw cycles than the Hudson Valley floor below. Water enters hairline cracks, expands overnight, and spalls the brick face by spring. The crown looks fine from the ground. The camera tells a different story.
• Dormant-summer flue damage. Seasonal homes sealed after Memorial Day collect moisture and animal nests all summer. By the first November fire, the cap has rusted through or the crown has cracked from internal freeze cycles the owner never saw. The creosote has condensed to glazed third-degree buildup that a brush alone won’t touch.
• One-size-fits-all caps on multi-flue fieldstone chimneys. A cap that doesn’t account for individual flue heights leaks at the flashing edge, not the crown. The homeowner pays for crown repair twice before realizing the cap was never seated right.
• Original lime mortar joints deteriorating under modern caps. Greenville’s pre-1940 chimneys were built with lime mortar that needs to breathe. Sealing them with impermeable crown coats or caps without ventilation traps moisture and accelerates joint failure. We match the repair to the original construction.
