Fast, Reliable Chimney Cap & Crown Across Old Greenwich
We know the chimneys here. The 1920s colonials along Sound Beach Avenue with their original clay flue tiles. The Cape Cods near Greenwich Point where the south-facing stacks take the full brunt of Long Island Sound’s salt wind. The shingle-style homes tucked between Riverside and Cos Cob where the mortar has been breathing that same damp, corrosive air for ninety years.
Our trucks cover 06870 regularly. From a call to your door, we’re typically there within the same day or next morning. We’ve been driving these streets since 1984, and we understand that an Old Greenwich homeowner doesn’t want a sales pitch - they want the thing fixed correctly, with no surprises on the bill, and a crew that shows up when they say they will.
That’s how we’ve operated for over 42 years. No app to download. No callback queue. Just a live person on the phone and a background-checked, uniformed technician at your door with the parts already on the truck.
Why Hearthstone Chimney Co. Is Old Greenwich’s Preferred Chimney Cap & Crown Company
We document what we find. Every inspection ends with photos you can see and a plain-English verdict - no jargon, no scare tactics. Our Level-2 camera inspections show you exactly where the crown has cracked or the cap has corroded, so you understand the repair before we start.
Our reputation here is local and long-standing. We’ve capped and re-crowned chimneys from Binney Park to the water’s edge, and Old Greenwich customers return because the job holds up. The 90-Day Done Right Promise governs every repair: Krafted right, Every time, Your home first, Standing behind it. In writing, no arguing.
Response time matters when water is entering your flue. We treat 06870 as a priority service area, not a distant add-on. Most cap and crown calls are scheduled same-day or next-day, and our technicians arrive with Famco and Copperfield inventory already stocked - no waiting on parts while rain gets into your chimney.
We know the coastal factor. Technicians working the streets closest to Greenwich Point routinely find flashing that has corroded through within 10-12 years rather than the 20-year lifespan expected inland. We specify stainless or copper on re-jobs here, because anything less is a temporary fix in this salt air.
Our Chimney Cap & Crown Services in Old Greenwich
Cap Installation
New cap installation in Old Greenwich runs $280-$520 for standard single-flue galvanized or stainless units, and $580-$1,100 for multi-flue or custom copper caps sized to the oversized or irregular flues common in pre-war homes here. We measure on-site, fabricate or order to fit, and install with proper clearances and secure mounting - critical in a waterfront ZIP where wind gusts off the Sound can lift poorly secured caps. Our Chimney Cap & Crown team carries Famco and Copperfield stock for same-day installation on standard sizes.

Cap Replacement
Replacement is our most common call in 06870, and there’s a reason. The salt-laden air off Long Island Sound accelerates cap deterioration at a rate noticeably faster than inland Fairfield County towns. A cap that might last 15 years in Stamford or Greenwich proper often shows through-rust in 8-10 years here. We remove the failed unit, inspect the flue and crown beneath for hidden damage, and install a replacement that matches or exceeds the original specification - stainless or copper for coastal durability.

Crown Repair
Crown repair in Old Greenwich typically costs $340-$680 for crack sealing, resurfacing, and edge restoration on accessible single-story stacks. The crown is the concrete slab that seals the top of your chimney between the flue tiles and the brick edge; when it cracks, water enters the masonry below and freeze-thaw cycles do the rest. In Old Greenwich’s 1920s-1950s housing stock, we frequently find original crowns poured too thin or without proper slope, compounded by decades of salt-air spalling. We rebuild with proper crown mix, reinforced edges, and adequate overhang to shed water away from the brick face.

Crown Coating
For crowns with minor cracking and adequate structural thickness, crown coating offers a cost-effective alternative to full rebuild. In Old Greenwich, this runs $180-$340 and buys significant protection when the underlying concrete is sound. We use professional-grade flexible coatings formulated for chimney exposure - not the hardware-store sealants that crack within a season. This is often paired with our Chimney Cleaning & Sweep in Old Greenwich to address the creosote accumulation that uneven coastal draft can cause.

Common Chimney Cap & Crown Problems We See in Old Greenwich Homes
- Salt-air corrosion on caps and flashing. The persistent onshore flow off Long Island Sound deposits chloride on metal surfaces, accelerating rust and pitting. We see this most severely on south-facing, water-side elevations near Greenwich Point, where standard galvanized caps may fail in under a decade.
- Crown spalling from freeze-thaw cycles. Old Greenwich’s coastal moisture penetrates micro-cracks in concrete crowns; winter temperatures drop below freezing, the water expands, and the surface flakes away. Original crowns on 1920s-1950s homes were often poured without modern air-entrainment additives, making them especially vulnerable.
- Downdraft-driven creosote staining. Variable wind pressure from the Sound can reverse draft in chimneys on exposed elevations, pushing smoke and moisture back down the flue. This stains the crown surface and can corrode the underside of the cap, a pattern we flag during every inspection.
- Undersized or missing caps on coal-era flues. Many Old Greenwich chimneys were built for coal or early oil systems with smaller flue diameters or multiple flues now abandoned. Modern inserts and stoves need properly sized caps with adequate clearance; we fabricate or source custom solutions when standard units won’t fit safely.

Our phones are staffed by a live person every hour of every day - not a voicemail system - so you reach us when you need us. Most emergency repairs are completed in a single visit.
Labor rates are consistent across our Fairfield County service area, but material specifications for Old Greenwich often run slightly higher due to the coastal environment.
