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 Commack Homeowners
A chimney cap and crown do one job: they keep water out of your flue and off your masonry. When either one fails, water gets in, freezes, thaws, and starts breaking brick and mortar apart from the inside. That’s the repair bill nobody wants. In our Chimney Cap & Crown in Commack, where winter freeze-thaw cycles hit chimneys hard, a cracked crown or missing cap is the single most common cause of expensive masonry damage we see. Wendell Pike has been fixing and installing caps and crowns across Commack and Suffolk County since 1999, and he’ll tell you straight whether yours needs work now or can wait. Call (631) 502-3612 and you’ll get a live person, not a call center.
Here’s the short version of what this page covers: what a cap and crown actually do, what it costs to fix or replace them, with our Chimney Cap & Crown cost guide for Commack, the warning signs to look for, and how we do the job without turning a simple repair into a five-thousand-dollar production. We’ll also tell you when you don’t need to spend a dime. That part matters to us as much as the work itself.
Key Takeaways
- A chimney crown is the concrete slab on top of the chimney; a cap is the metal cover over the flue opening. They work together to keep water out.
- Crown repair or recoating in Commack typically runs $300 to $900. Cap replacement usually lands between $250 and $650 including the cap itself.
- Every job comes with a written 90-Day Done Right Promise. If it isn’t right, one call brings Wendell back.
- We work with Olympia Chimney and Famco caps most often in Commack, and we stock common sizes on the truck.
What Our Chimney Cap & Crown Service Includes
This isn’t a one-size-fits-all job. Sometimes the cap is fine and the crown is shot. Sometimes the crown is solid but the cap blew off in a nor’easter and a raccoon moved in. Here’s exactly what we do under each part of this service, and how to know which one you need.
Cap Installation
A cap install is straightforward when the flue is in good shape and there’s no existing cap, or the old one rusted through. We measure the flue opening precisely, set the cap for proper draft clearance, and secure it so a winter gust off the Sound doesn’t send it into your neighbor’s yard. In Commack we mostly install stainless steel and copper caps from Olympia Chimney and Famco because they hold up to salt air and freeze-thaw conditions better than galvanized.
You need a cap if water has been getting directly into the flue, if birds or squirrels have been getting in, or if you can see daylight where there used to be metal. A missing cap in Commack is an open invitation for rain, leaves, and animals. We’ve pulled more squirrel nests out of uncapped flues than we care to remember.
Top Hat Chimney installs the cap, checks the crown while we’re up there, and gives you a photo of the finished work. No upselling, no “while I’m here” pitch. If the crown is fine, we say so and leave it alone.
Cap Replacement
Replacement is different from installation because the old cap has failed, and often the flue tile underneath has taken some damage from exposure. We remove the old cap, inspect the flue, and tell you if the tile is spalling or cracked before we put anything new on. Sometimes the answer is just a new cap. Sometimes the flue needs a little masonry work first. You’ll know before we do anything, with photos.
In Commack we see a lot of rusted galvanized caps that were installed twenty years ago and have been quietly failing for the last five. Salt air doesn’t help. A stainless cap from Olympia or Famco costs more up front but doesn’t do that. We’ll show you the difference and let you decide.
Everything we replace is backed by the 90-Day Done Right Promise in writing. If the cap shifts, leaks, or doesn’t fit right, we come back and make it right.
Crown Repair
The crown is the concrete or mortar slab that caps the top of the chimney structure, and in Commack it takes a beating. Water pools on it, freezes, thaws, and cracks form. Once cracks open up, water seeps into the brick below and the deterioration accelerates fast. A cracked crown left alone for a few winters becomes a much bigger masonry job.
We repair crowns by cleaning out the cracks, filling them with a bond that flexes with temperature changes, and re-sloping the surface so water runs off instead of pooling. If the crown is too far gone for a repair, we’ll tell you that too, and explain what a recast would involve and what it costs.
Wendell will show you the crown up close on camera before and after. You’ll see the cracks, see the fix, and get a plain-English explanation of whether it needs more attention down the road.
Crown Coating
Crown coating is a preventive measure for crowns that are aging but not yet structurally failing. We apply a flexible, waterproof coating that bridges hairline cracks and seals the surface against water intrusion. It won’t fix a crown that’s already crumbling, but it can buy years on one that’s showing early signs of wear.
For Commack homes, coating makes sense when the crown is five to ten years old and showing small surface cracks but no significant shifting or spalling. It’s a few hundred dollars versus the cost of a full recast, and it stops the freeze-thaw cycle from turning those hairline cracks into real damage.
We use commercial-grade waterproofing products from brands we trust, and we photograph the crown before and after so you can see exactly what was sealed and why.
Multi-Flue Cap
If your Kings Park or Commack home has a chimney with two or more flues, you may need a multi-flue cap that covers the entire top of the chimney rather than individual flue caps. These are custom-fitted to the crown dimensions and protect both the flues and the crown surface itself from water and debris.
Multi-flue caps are common on older Commack homes with a fireplace and a furnace flue sharing the same chimney. They’re also the better choice when the crown is in decent shape and you want to protect the whole top instead of just the flue openings. A well-fitted multi-flue cap can actually extend the life of the crown by keeping standing water off it.
We measure every dimension on-site, order from Olympia or Famco when possible, and custom-fabricate when the chimney is an odd size. No gaps, no guesswork, no cap that rattles in the wind.
Custom Cap
Some chimneys don’t fit a stock cap. Older masonry, unusual flue sizes, or a homeowner who wants a specific look all call for a custom cap. We’ve built custom caps for historic homes in Commack where the chimney is a hundred years old and nothing standard comes close.
Custom caps can be made from stainless steel, copper, or powder-coated finishes, and they’re fabricated to the exact dimensions of your flue and crown. Copper looks sharp and develops a patina over time; stainless is lower-maintenance and disappears against the sky. We’ll show you options and give you a firm price before anything is ordered.
The process takes a little longer than a stock install because the cap has to be fabricated, but the fit is worth it. A custom cap that fits right outperforms a stock cap that almost fits, every time.

Brands We Service for Chimney Cap & Crown
We install and service Olympia Chimney caps most often in Commack. Olympia makes a solid stainless cap with a lifetime warranty on the metal, and we’ve installed enough of them to know exactly how they behave in Suffolk County weather. The sizing runs true, the mesh keeps animals out without choking draft, and the finish holds up to salt air better than most. We keep common sizes on the truck, so if we come out for an inspection and find a missing cap, there’s a good chance the fix happens same visit.
Famco is the other name we reach for regularly. Famco caps are well-built and come in more size and style options, which matters when you’re dealing with an older Commack chimney that doesn’t fit standard dimensions. We also work with Copperfield caps for homeowners who want copper, and DuraFlex products when the job involves a liner as well. The point isn’t the brand on the box; it’s that we’ve installed and serviced hundreds of these units and we know which one fits your chimney and your budget. Whether you have an Olympia, a Famco, a Copperfield, or something else entirely, we can get it right.
If you have an existing cap from a brand we didn’t name, that’s fine too. We service what’s on your roof, not just what we sell. The camera doesn’t care who made the cap.
Signs You Need Chimney Cap & Crown Right Now
- Water in the firebox after rain. If you see dampness, water stains, or a musty smell in your fireplace after a storm, water is getting in from above. In Commack, that usually means a failed crown, a missing cap, or both. The longer it sits, the more it soaks into the masonry and the bigger the repair gets.
- Cracks in the crown visible from the ground. If you can see cracking, spalling, or pieces of concrete missing from the top of your chimney from the yard, it’s already well past the coating stage. Those cracks are funneling water into the brick below. Get it looked at before the freeze-thaw cycle makes it worse.
- Animal sounds in the chimney. Squirrels, birds, and raccoons all get in through uncapped flues. If you hear scratching or chittering, something has moved in. Once they’re out, a proper cap keeps them out. We’ve evicted enough raccoons from Commack chimneys to know this is not a DIY situation.
- Rust stains on the chimney exterior. Rust streaks running down the brick usually mean a steel cap or damper is rusting out and leaving water and iron deposits on the masonry. It’s a sign the cap has failed or is about to. Rust stains also mean the water that caused them is already inside the chimney system.
- Pieces of concrete or mortar in the yard or on the roof. If you find small chunks of concrete or mortar near the base of the chimney, the crown is actively breaking apart. That’s the most direct warning sign you’ll get. The crown is falling off piece by piece, and every piece that falls leaves a bigger opening for water.
One thing worth saying plainly: none of these problems get cheaper by waiting. A $400 crown coating done early beats a $2,500 crown recast done late, every time. If you’re seeing any of these signs in Commack, call (631) 502-3612 and we’ll take a look. The estimate is free, and if the problem is minor, we’ll tell you that too.
Our Chimney Cap & Crown Process - Step by Step
Here’s what happens when you call Top Hat Chimney about a cap or crown in Commack. No mystery, no price changes at the door, no stranger in a rental van.
- 1
You call and talk to a person. The phone rings at our office and a live person answers. Often it’s Wendell himself. You’ll describe what you’re seeing, we’ll ask a few questions about your chimney and when you last had it inspected, and we’ll book a time that works for you. No voicemail tag.
- 2
We inspect from the roof, not from the driveway. Wendell or one of his crew gets on the roof and looks at the cap, crown, flue, and masonry up close. We photograph everything with a camera that shows details you’d miss with the naked eye. You’ll see exactly what we see.
- 3
You get a plain-English verdict and a firm price. Before any tool comes off the truck, you’ll know what’s wrong, what needs to happen, what it costs, and what can wait. The number we quote is the number on the invoice. If the crown is fine and you just need a cap, that’s all we’ll quote you.
- 4
We do the work and document it. Cap installation or replacement is usually done same visit. Crown repairs take a little longer depending on the extent of the damage. We photograph the finished work and walk you through what was done and why. If we find something unexpected, we stop and call you before doing anything outside the agreed scope.
- 5
You get the 90-Day Done Right Promise in writing. Every completed job comes with a written guarantee. If the work isn’t right within 90 days, one call brings us back at no additional cost. Wendell puts his name on it, and he’ll run into you again at the hardware store, so it matters.
How Much Does Chimney Cap & Crown Cost in Commack?
A typical chimney cap installation or replacement in Commack runs $250 to $650, including the cap itself. The spread depends on flue size, cap material, and whether you need a stock size or something custom. Stainless steel caps from Olympia or Famco run $150 to $400 for the part alone, and labor for a standard install is usually one to two hours.
Crown work costs more because the surface area and material matter. A crown coating in Commack typically runs $300 to $600. A crown repair with crack filling and re-sloping goes for $400 to $900 depending on how much of the crown is damaged. A full crown recast, where we remove the old crown and pour a new one, runs $1,200 to $2,800 for most Commack chimneys. Multi-flue and custom caps add cost because they’re fabricated to order, usually landing between $500 and $1,200 installed.
What affects the price: roof pitch and chimney height, the condition of the surrounding masonry, whether we can access the chimney safely from an extension ladder or need lift equipment, and whether the flue tile needs attention before a cap goes on. All of that gets spelled out in your free estimate before you agree to anything. We don’t do add-on surprises. And remember: seniors and veterans get 10% off, always, and any repair over $200 qualifies for $40 off. Call (631) 502-3612 for a firm quote.

Frequently Asked Questions - Chimney Cap & Crown in Commack
A chimney cap is a metal cover over the flue opening that keeps rain, animals, and debris out of the flue. A chimney crown is the concrete slab that covers the top of the chimney structure, sealing the masonry from water. You need both because water entering the flue causes interior damage, and water entering the masonry through a cracked crown causes structural damage. In Commack’s freeze-thaw climate, either problem gets expensive fast if left alone.
A standard cap installation or replacement in Commack takes one to two hours on-site. Crown coating takes about an hour, crown repair with crack filling takes two to three hours, and a full crown recast usually takes one full day including setup, tear-out, pour, and cleanup. Custom cap fabrication adds a few days to a couple weeks for the part to be made, but the install itself is still just a couple hours.
Crown repair in Commack typically runs $400 to $900 depending on how much of the crown is cracked or spalling. A full crown recast runs $1,200 to $2,800 for most chimneys in the area. Crown coating, which is preventive rather than corrective, costs $300 to $600. Call (631) 502-3612 and we’ll give you an exact price after seeing the crown, not before.

We answer the phone 24/7, and we keep common cap sizes on the truck so a same-visit fix is often possible.

Every cap and crown job comes with our 90-Day Done Right Promise in writing. If the work isn’t done right within 90 days, one call brings Wendell back at no additional cost.

You don’t need to do much. Make sure the area around the chimney is accessible, move any patio furniture or vehicles that are directly below the roof access point, and keep pets inside during the visit. We’ll bring everything else, including the ladder, tools, camera, and safety gear. If you’re home during the appointment, Wendell will walk you through what he finds, but you don’t have to be there for the work itself.
