Level 1 sweep and inspection to the NFPA 211 annual standard - flue, crown, cap, and flashing checked and photographed
Chimney sweep logs do not sweep chimneys. They loosen some creosote - which then falls where a brush and vacuum still have to collect it.

We’ve been working on Wyandanch chimneys for decades. The neighborhood’s postwar Cape Cods and ranches east of Straight Path, along Mount Avenue and up toward the LIRR corridor, carry masonry stacks that were built for oil-fired boilers in the 1950s and 1960s and have been patched, re-routed, or reopened ever since. That history matters when you’re choosing what caps and crowns to install today. Our Chimney Cap & Crown team documents every flue with a Level 2 camera inspection before we quote anything. You see what we see.
Why Hearthstone Chimney Co. Is Wyandanch’s Preferred Chimney Cap & Crown Company
We’ve served Long Island communities for over 42 years. Wyandanch homeowners know our trucks. They also know we don’t quote cap and crown work until the camera has run the full flue length and the photos are on screen in plain English.
Our 90-Day Done Right Promise covers every job in writing. If it’s not right, we come back. No paperwork, no arguing. That’s the K.E.Y.S. code: Krafted right, Every time, Your home first, Standing behind it.
Calls are answered by a live person, 24/7. Not a callback queue. Our technicians are background-checked, uniformed, and carry professional-grade materials from HeatShield, Gelco, Olympia Chimney, and Famco. Most jobs finish in one visit with upfront pricing - the number on the estimate is the number on the invoice.
We know the local pattern. Wyandanch’s housing stock is distinct from newer Suffolk County subdivisions. The chimneys are older, the flue histories are complicated, and the worst upselling in our industry happens on exactly these homes. We built our process to stop that.
Our Chimney Cap & Crown Services in Wyandanch
Cap Installation
New cap installation in Wyandanch starts with understanding what the flue is actually venting. A cap sized for an oil boiler’s 8×12 clay-tile flue is wrong for a gas insert. We measure, camera-inspect, and spec the correct cap - single-flue, multi-flue, or custom - before anything ships. A typical new cap installation in Wyandanch runs $280-$450 including fitting and weather-sealing.
Cap Replacement
Most cap replacements we do in Wyandanch are removing rusted or improperly re-routed caps from the oil-to-gas conversion years. The old cap often masked a cracked crown or spalling brick beneath. We pull the cap, inspect the crown and flashing with the camera, and replace with a properly sized unit. Cap replacement in Wyandanch typically costs $320-$580 depending on flue count and access.
Crown Repair
The chimney crown on a 1960s Wyandanch ranch is usually a poured concrete wash that has cracked from decades of freeze-thaw and Atlantic moisture. We grind out the damaged material, rebuild the slope for proper drainage, and finish with a professional-grade coating. Crown repair in Wyandanch runs $450-$850. If the crown has failed completely and the brick beneath is saturated, full rebuild with coating is $850-$1,200.
Crown Coating
Crown coating is our most-requested preventive service in Wyandanch. After repair or on a sound existing crown, we apply a flexible, breathable sealant - we use HeatShield and Gelco products - that bridges hairline cracks and sheds water without trapping moisture in the masonry. A crown coating alone, when the underlying concrete is sound, typically runs $280-$450. For Wyandanch’s exposure to nor’easter wind-driven rain, this is the single best investment to extend crown life.
Multi-Flue Cap
Many Wyandanch Cape Cods have two or more flues - one for the original boiler, one for a fireplace or later addition - that were capped separately and inconsistently. A multi-flue cap from Famco or Olympia Chimney covers the entire chimney top with a single, properly flashed unit that stops rain between flues and unifies the crown protection. Multi-flue cap installation in Wyandanch runs $550-$950 depending on chimney dimensions and screen specifications.
Custom Cap
When a Wyandanch chimney has an odd flue spacing, an oversized flue from a converted oil boiler, or a decorative brick chimney pot that the homeowner wants preserved, we spec custom caps in copper or stainless steel. Custom work starts at $750 and is quoted after measurement and camera inspection.

Common Chimney Cap & Crown Problems We See in Wyandanch Homes
- Original clay-tile flue liners cracked for the wrong appliance. The 1945-1965 Cape Cods and ranches east of Straight Path were built with flues sized for oil boilers. When gas or pellet stoves were added informally, the flue was often too large or too small, creating creosote glazing and moisture collection above the damper where no one looks until the camera finds it.
- Nor’easter rain pounds flat ranch and Cape rooflines. Wyandanch’s position inland doesn’t protect it from Atlantic moisture. Sustained wind-driven rain finds gaps in flashing and spalls mortar at the chimney crown, a failure that repeats every winter on these low-slope roofs.
- Caps removed during boiler conversion, never properly replaced. When oil boilers came out, chimneys were often capped temporarily or re-routed. Then a pellet stove went in, the cap came off informally, and no Suffolk County permit was pulled. The result is an unlined or improperly lined flue with no inspection record and no cap sized for the new appliance.
- Crown wash cracked and sloped backward. The original poured-concrete crowns on Wyandanch’s postwar chimneys were rarely built with proper overhang or slope. Decades of freeze-thaw have cracked them, and many now hold water against the brick instead of shedding it. The damage is invisible from the ground.

FAQs - Chimney Cap & Crown in Wyandanch
Yes. An uncapped flue lets rain, animals, and debris enter, and accelerates mortar deterioration in Wyandanch’s freeze-thaw climate. Even if the flue is no longer active, moisture damage to the crown and brick will spread to adjacent structures and any active flues sharing the chimney. Call (934) 348-4832 and we’ll camera-inspect to determine whether the flue should be capped, lined for a new appliance, or properly sealed - estimates are free.
Not necessarily removed, but it must be inspected and may need to be relined. The original clay-tile liner was sized for an oil boiler, not a pellet stove, and creosote from wood pellets burns differently than oil residue. Our Level 2 camera inspection shows whether the liner is intact, properly sized, or creating a hazardous accumulation zone. We won’t recommend relining without photo evidence you can see for yourself. Call (934) 348-4832 for a camera inspection and exact quote.
The poured-concrete crown wash on 1950s-1960s Wyandanch chimneys was rarely built with proper slope, overhang, or reinforcement. Decades of Atlantic moisture and freeze-thaw have cracked most of them, and many now slope toward the flue instead of away from it. Crown coating or rebuild is the fix, but only after camera inspection confirms the brick beneath is sound. A typical crown repair with Gelco coating runs $450-$850 in Wyandanch.
Box-store caps are thin galvanized steel with weak mesh and no proper flashing integration. They rust through in Wyandanch’s coastal-influenced climate within a few seasons, and they don’t seal between flues where rain enters and freezes. Famco and Olympia Chimney multi-flue caps are 304 stainless steel, properly flashed, and engineered for the exact flue spacing. We install them because we’re coming back in ninety days if they fail, and we don’t come back.
We show you. Every recommendation is backed by photos from our Level 2 inspection camera, displayed on screen in your home, with a plain-English verdict. No camera evidence, no quote. If the crown has minor cracking and the flue is sound, we’ll tell you that and quote coating only. If work can safely wait a season, we’ll say so. The 90-Day Done Right Promise is in writing - we only promise what we can stand behind. Call (934) 348-4832 for a free estimate with full camera documentation.
On a postwar ranch east of Straight Path, our tech pulled a rusted single-flue cap off a clay-tile flue that had been reopened for a pellet stove insert, and the Level 2 inspection camera showed third-degree creosote glazing and a cracked chimney crown shedding mortar at the flashing. We reset the crown with a Gelco coating, dropped a properly sized DuraFlex flue liner, and set a Famco multi-flue cap - the homeowner watched the whole camera run on screen before we quoted a thing. Done right, and we stand behind it.
