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.

AfterFast, Reliable Chimney Cap & Crown Across Westbury
Chimney cap and crown work in Westbury typically runs $280-$890 depending on whether you need a simple cap installation or full crown coating with flashing reseal, and most jobs are completed in a single visit with our crew already working Nassau County daily. We’re familiar with the postwar Capes and ranches off Jericho Turnpike and the blocks surrounding the LIRR Westbury station, where decades of coastal salt air and train vibration create a specific two-part failure pattern we’ve documented on hundreds of inspections. If you’re seeing water stains on the ceiling near your chimney, or if your crown looks chalky or cracked from the ground, call us at (845) 757-0998. A live person answers 24 hours a day, and we’ll schedule a Level 2 camera inspection that ends with photos you can see and a plain-English verdict.
Why Hearthstone Chimney Co. Is Westbury’s Preferred Chimney Cap & Crown Company
We’ve been answering the phone with a live person for over 42 years, and that steady presence matters to Westbury homeowners who’ve lived through enough contractor disappearances. Our dispatch and scheduling are coordinated from our New York City office, but our crews serve Westbury locally and know the difference between a 1952 Cape off Post Avenue and a 1960s ranch near the Northern State Parkway.
Our 90-Day Done Right Promise is backed in writing with no arguing - if it’s not right, we come back. That matters on cap and crown jobs where the real test is the first hard rain after we’re gone. Our background-checked, uniformed technicians carry professional-grade materials from Gelco, Olympia Chimney, and Famco, and most jobs are completed in a single visit with no-hassle upfront pricing. The number on the estimate is the number on the invoice.
We don’t upsell. Nothing is recommended without camera evidence you can see on the tablet, and we’re plain about what can wait versus what can’t. That’s the Keystone Standard we’ve operated under since 1984.
Our Chimney Cap & Crown Services in Westbury
Cap Installation
A proper chimney cap keeps rain, squirrels, and wind-blown debris out of your flue while allowing smoke and gases to vent freely. In Westbury, we size caps for the original flue dimensions common to postwar construction - typically 8×8 or 8×12 clay-tile openings on Capes and ranches built during the 1947-1965 Long Island boom. We install stainless steel and copper caps from Olympia Chimney and Famco, with mesh screening appropriate for your fuel type. A single-flue cap installation in Westbury typically runs $280-$450 installed.
Cap Replacement
Many Westbury homeowners call us when their existing cap is rusted through, blown off in a coastal storm, or was never properly secured to begin with. We remove the old unit, inspect the flue tile and crown condition beneath it, and install a replacement sized to fit. If your original cap was a cheap galvanized unit from a big-box store, the salt air off Long Island Sound has likely eaten it alive. We replace with marine-grade stainless or copper. Cap replacement in Westbury generally runs $320-$520.
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. On Westbury’s 60-to-75-year-old original brick stacks, crowns are often the first thing to fail. The salt-laden air and persistent coastal humidity accelerate mortar erosion and brick spalling at a rate simply not seen in inland Nassau County suburbs. We grind out deteriorated crown material, rebuild with proper slope and overhang, and seal with a waterproofing treatment. Crown repair in Westbury typically runs $450-$780.
Crown Coating
For crowns with hairline cracking but sound structural integrity, we apply a flexible cementitious coating - we use Gelco CrownCoat for its bond to existing concrete and its ability to bridge small cracks through freeze-thaw cycling. This is a common and cost-effective solution on Westbury Capes where the crown is cracked but the brick beneath is still sound. Crown coating runs $380-$650 in Westbury, and we warranty the application for five years.
Multi-Flue Cap
Many Westbury ranches and split-levels have two flues - one for a fireplace, one for a furnace or water heater - sharing a single chimney structure. A multi-flue cap covers both flues with one properly sloped hood, eliminating the gap between separate caps where water pools. We fabricate and install multi-flue caps to your chimney’s exact dimensions, with proper clearance and mesh. Multi-flue cap installation in Westbury runs $520-$890.
Custom Cap
For oversized flues, decorative applications, or heritage brickwork where standard sizes won’t do, we measure and specify custom caps in stainless or copper. Custom work starts at $680 in Westbury and is quoted after measurement.

Trusted Brands We Service in Westbury
We work exclusively with professional-grade materials - no builder-grade substitutes that’ll fail in three seasons. For cap and crown work in Westbury, we stock and install Gelco crown coatings, Olympia Chimney stainless caps, and Famco multi-flue and custom-fabricated units. These are brands that stand behind their products the way we stand behind our work. Because we carry inventory for Nassau County jobs, most Westbury cap and crown replacements don’t require a second trip for parts. That means your job gets done in one visit, and you’re not waiting two weeks for a back-ordered cap while water keeps getting in.
Common Chimney Cap & Crown Problems We See in Westbury Homes
- Original 1950s crowns cracked from coastal salt-air freeze-thaw. The persistent humidity and salt air off the Atlantic and Long Island Sound hasten mortar erosion on exposed chimney crowns. Meltwater sits in the cracks, wicks into the top brick courses, and by the time you see a ceiling stain, you’re looking at crown repair plus interior damage. Annual inspection catches this before the water gets inside.
- Train vibration near the LIRR Westbury station corridor loosens flashing seals and crown caps together. Decades of vibration from the Long Island Rail Road works flashing nails loose and cracks crown mortar at the flue penetration. A cap alone won’t stop the leak if the step flashing has pulled away from the brick. Our techs working the blocks near the station routinely find this two-part failure and address both.
- Unlined or clay-tile flues now running wood inserts or gas appliances they were never sized for. Many Westbury chimneys were originally engineered for fuel-oil or coal flue gases. Homeowners add a wood-burning insert or gas log set, but the flue is too large for the new appliance’s lower exhaust temperature. Draft is weak, creosote builds faster, and the cap that worked fine for oil heat may not provide adequate venting for the new setup. We flag this during inspection and discuss liner options when the camera proves it’s needed.
- Galvanized caps rusted through in 3-5 years from salt air exposure. The cheap cap from the hardware store seemed fine until it wasn’t. We replace with marine-grade stainless or copper that handles Westbury’s coastal environment for decades, not seasons.

What moves you within these ranges? Crown condition is the big variable. A crown with surface cracking but sound structure gets coated. A crown that’s spalled, pitched wrong, or separating from the brick needs repair or rebuild. Flashing condition adds cost when train vibration or age has compromised the seal. We give you the camera footage and a plain-English verdict before any work is authorized. No surprises on the bill.

FAQs - Chimney Cap & Crown in Westbury
Yes, because the crown protects your chimney structure regardless of how often you use the fireplace. On Westbury’s original 1950s brick stacks, the crown is typically 60-plus years old and was poured with a mortar mix less durable than modern formulations. Coastal salt air and freeze-thaw cycling crack it whether you burn or not. Once water gets through, it damages the brick below and can rot ceiling joists. A cap and crown coating is preventive maintenance that costs far less than rebuilding the top courses. Call (845) 757-0998 for a free inspection and exact quote.
Decades of train vibration works flashing nails and sealant loose while the same freeze-thaw cycling that cracks crowns also degrades the flashing-to-brick interface. It’s a combined failure mode we document regularly on the postwar Capes and ranches within a few blocks of the rail corridor. Fixing one without the other leaves a path for water. Our Chimney Cap & Crown team addresses both during the same visit when the camera proves both are compromised.
First-degree creosote is dry, flaky, and brushes off easily - what you see with good burning habits and adequate draft. Third-degree creosote is thick, tar-like, and glazed to the flue wall; it restricts airflow, increases fire risk, and is much harder to remove. On Westbury chimneys with unlined or oversized flues running modern appliances, we often find third-degree buildup because the flue stays too cool for complete combustion. The cap doesn’t cause this, but a properly sized cap with adequate mesh and clearance helps maintain the draft that minimizes creosote formation. We check creosote grade during every Level 2 inspection and show you the camera footage.
We can install a multi-flue cap on any structurally sound chimney with proper flue spacing and height. The question is whether your flues are properly lined and sized for what you’re actually burning. Many Westbury chimneys have 8×8 or 8×12 clay-tile flues originally engineered for fuel-oil exhaust - larger than ideal for modern gas or wood appliances. The multi-flue cap fits fine. But if the camera shows creosote buildup or draft problems from the flue mismatch, we’ll flag the liner issue separately and let you decide what to address when. No upsell, just what the camera proves.
We won’t quote crown coating without looking at the crown from the top and inside the flue. A Level 2 inspection with camera is how we determine whether coating is sufficient or the crown needs rebuild, and whether there are underlying issues - liner condition, creosote buildup, or hidden water damage - that should factor into your decision. The inspection runs $89 as our Seasonal Tune-Up special, and if you proceed with the work, that fee is credited toward your cap or crown job. Call (845) 757-0998 to schedule - estimates are free, and the inspection gives you the full picture.
