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.

AfterTrusted Chimney Cap & Crown for Northport Homeowners
A Chimney Cap & Crown in Northport typically costs between $450 and $1,800 depending on whether you need a simple cap replacement or full crown rebuild, and most jobs are completed in a single visit. Hearthstone Chimney Co. has installed and repaired hundreds of caps and crowns across Northport’s older homes since 1984, and we back every job with our 90-Day Done Right Promise in writing. Call us at (631) 528-2501 for a free estimate with upfront pricing.
Northport’s coastal position on Long Island’s north shore means our chimneys take a beating. The salt air off Long Island Sound accelerates metal cap corrosion. Freeze-thaw cycles crack concrete crowns every winter. And the mature oak and maple canopy throughout neighborhoods like Eatons Neck and Asharoken drops debris that clogs uncapped flues. We’ve seen what happens when a crown crack goes unaddressed through a wet February, and we’ve seen how a properly fitted cap from Gelco or Olympia Chimney can add fifteen years to a chimney’s life.
We’re not a chain operation sending whoever’s available. Our technicians are background-checked, uniformed, and trained specifically in cap and crown work. Every inspection ends with photos you can see and a plain-English verdict. No jargon, no pressure, no surprises on the bill. That’s how we’ve operated for over 42 years, and that’s why Northport homeowners still call us.
What Our Chimney Cap & Crown Service Includes
Cap Installation
A chimney cap is the metal cover that sits atop your flue, keeping rain, animals, and debris out while letting smoke escape. You need one if your flue is open to the sky, which it is on most Northport homes built before 1990. We measure your flue precisely, then install a cap from Olympia Chimney or Gelco with stainless steel fasteners and a proper storm collar. Most installations take under an hour and are done right the first time.
Cap Replacement
Caps rust, warp, or blow off in nor’easters. If your cap is missing, rattling, or visibly corroded, it’s not protecting your flue. We remove the old unit, inspect the flue tile for hidden damage that the failed cap may have allowed, then install a replacement sized exactly to your chimney’s dimensions. We stock common sizes for Northport’s colonial and cape-style homes, so you’re not waiting on a special order.
Crown Repair
The crown is the concrete slab that seals the top of your chimney between the flue tiles and the brick edge. Cracks here let water straight into the chimney structure, causing brick spalling and interior damage that costs far more to fix. For minor cracking, we clean the surface and apply a flexible crown sealant that bridges hairline fractures and sheds water. For more significant damage, we cut out the compromised section and pour new concrete with a proper drip edge and slope.
Crown Coating
When a crown is structurally sound but weathered, coating extends its life without the cost of full replacement. We use professional-grade elastomeric coatings formulated for chimney crowns, not generic masonry paint. The process involves thorough cleaning, crack filling, and two coats applied to manufacturer specifications. A coated crown in Northport typically lasts 8-12 years before needing reapplication, depending on sun exposure and how close you are to the water.
Multi-Flue Cap
Some Northport homes, especially the larger colonials near the harbor, have multiple fireplaces sharing one chimney structure. A multi-flue cap covers all flues with a single unit, providing cleaner lines and often better protection than individual caps. We fabricate and install multi-flue caps with proper clearance heights and mesh sizing to handle multiple appliances safely. These require precise measurement, and we document every dimension before ordering.
Custom Cap
Historic homes, unusual flue configurations, or chimneys with external structural elements sometimes need a cap built to order. We’ve fabricated custom caps for Northport’s Victorian-era properties and for homeowners who want copper or specific architectural details. We measure twice, specify the materials, and oversee fabrication. The result fits like it was made for your chimney, because it was.

Brands We Service for Chimney Cap & Crown
We work exclusively with professional-grade materials from manufacturers who stand behind their products the way we stand behind ours. We’ve installed hundreds of Gelco caps across Suffolk County. Their stainless steel construction holds up to salt air better than the galvanized units you’ll find at hardware stores, and we stock their most common sizes so Northport homeowners aren’t left waiting.
Olympia Chimney is another brand we specify regularly, especially for multi-flue and custom applications. Their engineering tolerances are tight, which means fewer callbacks for fit issues. We also have deep experience with DuraFlex components when crown work connects to liner repairs, and HeatShield products for related flue restoration. Whether you have one of these brands or any other make, we can help. We’ll tell you honestly if your existing cap is worth saving or if replacement is the smarter spend.
Signs You Need Chimney Cap & Crown Right Now
- Water stains on your ceiling near the fireplace. This means moisture is entering through the chimney top, running down the flue, and finding its way into your living space. In Northport, where winter temperatures fluctuate above and below freezing, that moisture expands and contracts inside your walls, turning a small leak into structural damage over a single season.
- Visible cracks in the concrete crown. Hairline cracks widen. Water seeps in, freezes, and pries the concrete apart. By the time you see pieces missing, water has likely reached the brick below. We catch this early with camera inspections and fix it before your chimney needs rebuild work.
- Rust stains running down the brick from the cap. Rust means your cap is failing. Once the metal is compromised, it’s not protecting your flue from rain or animals. We’ve removed caps from Northport chimneys that were more rust than metal, and the flue tiles underneath were damaged from years of exposure.
- Birds, squirrels, or debris in your fireplace. An uncapped flue is an open door. Raccoons in particular favor Northport’s mature tree canopy and will den in chimneys. A proper cap with the right mesh size keeps wildlife out without restricting draft.
- Spalling brick or deteriorating mortar on the chimney exterior. This damage starts at the top. A failed crown lets water saturate the masonry, and freeze-thaw cycles pop the brick faces off. Fixing the crown is the only way to stop the progression. Tuckpointing alone just hides the symptom.

How Much Does Chimney Cap & Crown Cost in Northport?
Our Chimney Cap & Crown cost guide shows how Northport prices vary with the scope of work, the materials specified, and access conditions. Here’s what typical jobs run in our market:
| Service | Typical Range in Northport | What Affects Price |
|---|---|---|
| Standard cap installation | $450 - $750 | Flue size, cap material (galvanized vs. stainless), height/access |
| Cap replacement | $400 - $650 | Condition of existing fasteners, flue tile damage underneath |
| Crown coating | $600 - $950 | Crown size, crack severity, number of coats required |
| Crown repair (partial) | $800 - $1,400 | Extent of concrete removal, reinforcement needs |
| Full crown replacement | $1,200 - $1,800 | Chimney dimensions, forming complexity, curing time |
| Multi-flue cap | $700 - $1,200 | Number of flues, overall dimensions, material grade |
| Custom cap (fabricated) | $900 - $1,500+ | Material (copper, stainless), design complexity, finish |
Several factors push costs toward the higher end. Chimneys on three-story homes or with steep roof pitches require additional safety equipment and time. Homes near the water in Eatons Neck or Fort Salonga often need premium stainless steel to resist salt corrosion. And if the flue tiles beneath a failed cap are damaged, that repair adds to the scope.
The best way to avoid overpaying is to address problems early. A $600 crown coating now prevents a $1,600 rebuild later. And never agree to major chimney work without seeing photo evidence. We show you exactly what we found and exactly what we recommend. If something can wait safely, we say so plainly.
Our estimates are free, and our $50 off any repair over $250 applies to cap and crown work. We also offer a free second opinion on any written estimate you’ve received from another company. Call (631) 528-2501 for exact pricing on your chimney.

Frequently Asked Questions - Chimney Cap & Crown in Northport
The cap is the metal cover that sits over your flue opening to keep out rain, animals, and debris. The crown is the concrete slab that tops your chimney structure and sheds water away from the brick. You need both because the cap protects the flue interior while the crown protects the chimney structure itself. In Northport’s wet, coastal climate, missing or damaged caps and crowns are the leading cause of premature chimney deterioration, which is why we also serve nearby Chimney Cap & Crown - Centerport.
Most cap installations and replacements are completed in under an hour. Crown coatings take 2-3 hours including surface preparation and cure time.
