Water dripping down your flue in a Nesconset ranch on Old Nichols Road? You’re not imagining it.

Call (844) 803-1545 - a live person answers, even at 10 PM on a Sunday.
We’ve been driving to Nesconset since 1984. We know the 11767 zip code well: the split-levels near Gibbs Pond Park, the Cape Cods tucked behind Smithtown Boulevard, the ranches lining Southern Boulevard toward Lake Ronkonkoma. These homes were built fast during the 1960s and 1970s Suffolk County boom, and their chimneys are aging out together. When your crown has hairline cracks or your cap blew off in a nor’easter, you want someone who understands what 50 years of Long Island freeze-thaw cycles have done to single-wythe brick - not a dispatcher in another state reading from a script.
Why Hearthstone Chimney Co. Is Nesconset’s Preferred Chimney Cap & Crown Company
Local reputation built over four decades. Nesconset homeowners call us back because we document what we find. Our Level-2 camera inspection ends with photos you can see and a plain-English verdict - no jargon, no scare tactics. We’ve earned a strong local reputation across Suffolk County by treating every chimney like it’s our own.
Response time that respects your schedule. We’re on the road early from our base serving Suffolk County, which means Nesconset calls typically get same-day or next-day scheduling. Most cap and crown jobs finish in a single visit. We’ll be there when we say.
We understand your specific chimney. Nesconset’s housing stock is unusual: most chimneys here were built to vent both a fireplace and an oil-fired boiler. That dual-flue design, now 50-60 years old, creates cap and crown problems you won’t see in newer construction. We’ve repaired hundreds of them. We know where the weak points form.
The 90-Day Done Right Promise. Every cap installation, every crown coating, every repair - backed in writing. If it’s not right, we come back. No paperwork to dig up, no arguing. That’s the Keystone Standard we’ve kept since 1984.
Our Chimney Cap & Crown Services in Nesconset
Cap Installation
New cap on a Nesconset home that never had one? We see this often on Gibbs Pond Road and the surrounding 1960s ranches where the original builder skipped it or the old cap rusted through. A proper cap - we typically install Famco or Copperfield galvanized or stainless models - keeps Suffolk County’s driving rain out of your flue and stops squirrels from nesting above your damper. A typical cap installation in Nesconset runs $280-$450, including fitting to your flue size and a weather-tight seal.
Cap Replacement
Caps don’t last forever on Long Island. Coastal humidity reaches Nesconset even this far inland, and cheap hardware-store caps corrode in five to seven years. We replace them with professional-grade units sized precisely to your flue. If your chimney has two flues - the classic Nesconset fireplace-and-oil-burner setup - we’ll fit a multi-flue cap or individual caps as the condition dictates. Most replacements in Nesconset fall between $320 and $520.
Crown Repair
The crown is the concrete slab that tops your brick chimney, and it’s where Nesconset’s freeze-thaw damage shows first. Temperatures here oscillate around 32°F dozens of times each winter, opening hairline cracks that widen every season. We repair crowns with proper concrete formulation - not thin caulk that’ll crack by March - sloped to shed water away from your flue. Crown repair in Nesconset typically costs $380-$620 depending on accessibility and how far the cracking has spread.
Crown Coating
For crowns with early-stage cracking but sound structure, we apply a flexible crown coating that bridges small gaps and seals against further water intrusion. This isn’t a permanent fix for a crumbling crown, but it’s a square deal for the right chimney - and it costs less than full rebuild. In Nesconset, crown coating runs $280-$420. We’ll tell you honestly whether your crown qualifies or needs repair instead. Photos you can see, a plain-English verdict.

Common Chimney Cap & Crown Problems We See in Nesconset Homes
- Missing or wind-loosened caps after coastal storms. Nesconset sits close enough to Long Island Sound to feel the backside of nor’easters. We’ve replaced caps on Southern Boulevard homes where the original was held by two rusty screws and a prayer.
- Crown cracks from five decades of freeze-thaw. The 1960s-1970s construction boom here means crowns were poured with less reinforcement and lower-grade concrete than modern standards. Hairline cracks are nearly universal on 50-year-old Nesconset chimneys.
- Abandoned oil-burner flues left uncapped after gas conversion. This is the Nesconset special. A homeowner switches to gas, the oil flue sits open, and rainwater runs down the cracked clay tile liner with nowhere to go. We find this scenario on street after street in the 11767 zip.
- Spalling brick beneath failed crowns. Once the crown lets water into the chimney structure, Nesconset’s persistent humidity keeps masonry damp year-round. Brick faces pop off, mortar joints crumble, and the repair bill grows. Catching it early saves the chimney.

The extent of hidden damage once we open it up: a crown that looked cracked can reveal spalled brick beneath, or a flue that seemed sound can show glaze cracking from decades of oil soot.

FAQs - Chimney Cap & Crown in Nesconset
We typically schedule Nesconset inspections within 24 hours, and most cap or crown repairs complete same-day or next. Our technicians start early from Suffolk County routes, and Nesconset’s location near Smithtown Boulevard puts you on our regular path. Call (844) 803-1545 - a live person answers 24/7 to set your appointment.
Yes. We work throughout the 11767 zip code, from the ranches along Old Nichols Road and Southern Boulevard to the split-levels near Gibbs Pond Park and the Cape Cods tucked behind Smithtown Boulevard. Your chimney’s age and condition matter more to us than your exact street - and in Nesconset, we already know what 50-year-old chimneys look like.
Active water intrusion into your chimney is urgent - not because your house will flood tonight, but because every rainfall causes more damage to mortar, liner, and surrounding structure. In Nesconset’s climate, where humidity stays high and freeze-thaw cycles restart each winter, delaying crown or cap repair guarantees a larger bill later. We treat water-intrusion calls as priority scheduling. Call (844) 803-1545 for a free estimate.
Nesconset pricing falls in line with central Suffolk County rates - slightly lower than North Shore premium areas, comparable to Lake Ronkonkoma and Ronkonkoma, and competitive because we complete most jobs in one visit without return trips. The unique factor here is chimney age: Nesconset’s uniform 1960s-1970s housing stock means we encounter predictable problems, so our estimates tend to be accurate. No guessing, no padding.
Every job is covered by our 90-Day Done Right Promise - in writing, no arguing. If the cap leaks, the crown coating fails, or anything isn’t right, we return and fix it at no charge. Beyond that, manufacturer warranties apply: Famco and Copperfield caps carry their own material guarantees, and our installation workmanship is guaranteed for the full 90 days. We’ve been in business since 1984; we plan to be here when you need us next.
