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 Astoria Homeowners
A damaged chimney crown or a missing cap is the fastest way to turn a Queens brick chimney into a water-damage repair bill. In Astoria Chimney Cap & Crown territory, where winter freeze-thaw cycles and salt air off the East River both work on masonry, most of the crowns we inspect on prewar rowhouses and postwar brick colonials are already cracked by year fifteen. We’re Level Two Chimney Astoria, and we’ve documented more than 38,000 chimney inspections and cleanings since 2009, always with a camera down the flue and a written price before any work starts.
If you’re seeing water in the firebox, efflorescence on the chimney face, or you just looked up and realized the cap is gone entirely, we can usually get a technician to your Astoria block within a few days. Call (516) 301-1549 and you’ll talk to a live person, not a voicemail.
What Our Chimney Cap & Crown Service Includes
Most Astoria homeowners call us for one of six reasons. Here’s exactly what each involves, when it applies to your chimney, and what we do differently. Every job starts with the same baseline: a camera scan of the flue, a written scope of work, and a price you see before anything gets touched.
Cap Installation
A chimney cap is the stainless steel or copper lid that sits over the flue opening. Without one, rain falls directly down the flue, and Astoria’s pigeon population finds a ready-made roost. We install standard single-flue caps, and we always measure the flue tile before ordering so the cap actually fits the liner, not just the brick. Every cap is secured with stainless fasteners, never tap-cons that rust out in three seasons.
Cap Replacement
If your existing cap is rusted through, bent from a storm, or the screen mesh has separated from the frame, replacement is almost always cheaper than repair. We pull the old cap, check the flue tile crown underneath for damage while it’s exposed, and install the new cap the same visit. You leave with photos of the old cap, the new cap, and a written warranty card with the install date.
Crown Repair
The crown is the concrete slab that forms the chimney’s roof. It sheds water away from the flue tiles. When it cracks or spalls, water seeps into the brick below and freezes. In Astoria, that freeze-thaw cycle runs from November through March, and each cycle widens the crack. We repair crowns with a proper wash slope, a drip edge that overhangs the brick at least two inches, and a flexible sealant that moves with the masonry instead of cracking like mortar.
Crown Coating
When a crown is structurally sound but porous, we coat it rather than replace it. The coating is a rubberized elastomeric that bridges micro-cracks and gives the crown a watertight membrane. This is the right call when the camera scan shows the flue liner is fine and the crown just needs to stop absorbing water. We use Gelco crown seal and other materials we’ve tested across thousands of New York chimneys, and we document the before-and-after on camera.
Multi-Flue Cap
Many rowhouses in Chimney Cap & Crown - Long Island City and nearby Astoria have two or three flues sharing one chimney chase. A single-flue cap won’t cover that footprint, and the gap between flues is where water and birds get in. We custom-cover multi-flue chases with a cap that spans the full crown, with a screen mesh sized to keep out birds and raccoons but not restrict draft. The difference is a cap that actually covers the entire opening, not just the individual flues.
Custom Cap
Older chimneys with non-standard flue sizes, rectangular terra cotta liners, or decorative brickwork - common in Chimney Cap & Crown in Jackson Heights and Astoria alike - often need a fabricated cap. We measure on site, then build to spec using stainless steel or copper. A custom cap is the only option when the flue opening is an odd dimension that off-the-shelf caps don’t fit, and covering it with a too-small cap defeats the purpose. We’ll show you the design and price in writing before we build anything.

Brands We Service for Chimney Cap & Crown
We work with caps, crowns, and flashing systems from every major manufacturer, but most of what we install in Astoria comes from Olympia Chimney and Famco. Olympia’s stainless caps are what we recommend for most single-flue and multi-flue installations because the mesh gauge is thick enough to survive a Queens pigeon colony and the metal holds its finish for a decade or more. We stock standard Olympia sizes in the truck, so most installations don’t wait on shipping.
Famco is our go-to for custom-fabricated caps when an Astoria chimney has a non-standard flue opening or unusual crown geometry. We’ve measured, ordered, and installed enough Famco units to know their lead times and tolerances, and our techs can quote the build to spec without a second site visit. For crown repair and resurfacing, we work with Gelco and HeatShield products. Whether you have an Olympia, Famco, or a no-name cap from the previous owner, we can service it or replace it with something better.

Before
AfterSigns You Need Chimney Cap & Crown Right Now
- Water in the firebox after rain. Water shouldn’t reach the firebox through a properly capped flue and an intact crown. If it does, the water is entering from above, and every storm is doing more damage. The longer it runs, the more it soaks into the smoke chamber and the softer the masonry gets.
- White staining on the exterior brick. Efflorescence is salt and mineral deposit pushed out of the brick by water moving through it. It means the crown has been failing for at least a season, not a week. The brick face is wet on the inside, and freezing temperatures will start popping faces off the brick.
- Pieces of concrete on the roof or in the gutter. When you see crown fragments below the chimney, the crown is actively spalling. It’s not a future repair. It’s a current one, and the exposed mortar joints below it are already taking on water.
- Birds in the flue or chimney. Pigeons and starlings enter through an uncapped or improperly sized flue opening. Once they nest, the chimney can’t draft properly, and bird mites, droppings, and odor move into the house. We’ve pulled enough dead birds out of Astoria flues to know this isn’t rare.
- Strong draft or smoke backup. A missing or wrong-sized cap changes how air moves through the flue. If wind blows smoke back into the living room or the fire won’t draw, the cap is often the culprit, and the math on a proper cap is simple: a few hundred dollars to fix a performance problem that makes the fireplace unusable.
Our Chimney Cap & Crown Process - Step by Step
You should know exactly what happens when you book with us. Here’s the full sequence, no surprises.
- 1
Call or book online, and we set the appointment. The person who answers the phone is in our office, not a call center. We’ll ask about your chimney’s age, what symptoms you’re seeing, and whether you can safely access the roof from inside or if we need a ladder. You’ll get a text with your technician’s name and a time window before they arrive.
- 2
On-site inspection with camera documentation. Your technician, background-checked and uniformed, runs a camera down the flue and documents the crown, cap, flashing, and liner on video and stills. You get to see what we see. Clause 4 of the Haven Standard requires a photo record on every job, and we’ve done that on every visit since 2009, not just on big jobs.
- 3
Written scope and price before any work starts. After the inspection, we write out what’s actually wrong, what we recommend, and what it costs. Line by line. If the crown can wait a season, we say so. If the liner is fine, we say so. You approve the work before a tool comes out, and the price doesn’t change after the fact.
- 4
The repair or installation, done on the spot when possible. Most cap replacements and crown repairs are completed the same visit. We have the materials, the fasteners, and the sealants on the truck. You get photos of the finished work from the roof and from inside the flue if we can get the camera up there.
- 5
Documented record and written warranty in hand. Before we leave, you get a written summary of what was wrong, what we did, what we used, and photos of the finished job. The warranty is written, not verbal: what’s covered, for how long, and who to call if something needs attention. That’s the whole point of the Haven Standard.
How Much Does Chimney Cap & Crown Cost in Astoria?
In Astoria, a standard stainless single-flue cap installation runs $325 to $550 including the cap and labor, as detailed in our Chimney Cap & Crown cost guide. A multi-flue cap covering a full rowhouse chase runs $650 to $1,100. Crown repair with crack filling and a elastomeric coating typically runs $400 to $800, while a full crown rebuild with proper wash slope and drip edge runs $1,200 to $2,400 depending on access and masonry condition. Custom caps run higher, starting around $700 and going up based on dimensions and material.
What moves the price: roof access (a three-story walkup with a steep pitch costs more than a two-story flat roof), the size of the flue opening, whether the crown is salvageable or needs full removal, and whether scaffolding is required. Nearly every Astoria rowhouse roof we work on requires ladder access from the street side or rear yard, and we include that in the written quote anyway. The best way to avoid overpaying is to get a specific, written line-item price before work starts, not a vague “we’ll see when we get up there.” We do that on every job, no exceptions. If another company has given you a written estimate, bring it to us. We’ll give you a free second opinion on it.

Frequently Asked Questions - Chimney Cap & Crown in Astoria
A chimney cap is the metal lid over the flue opening that keeps out rain, birds, and debris. A crown is the concrete slab at the top of the chimney that sheds water away from the brick. Both work together: the crown protects the masonry, the cap protects the flue, and when either fails, water gets into places you can’t see until the damage is serious.
Most single-flue cap installations and crown repairs are finished in two to three hours on site. Full crown rebuilds usually take four to six hours, depending on access and the size of the chimney. We don’t charge by the hour; you get a written price before we start, and the time on site doesn’t change it.
A standard cap installation in Astoria runs $325 to $550, a multi-flue cap runs $650 to $1,100, and crown repair runs $400 to $800, with full rebuilds starting around $1,200. Your exact price depends on roof access, flue size, and the condition of the existing crown. Call (516) 301-1549 and we’ll give you a written number, not a guess.
Yes. We install and replace Olympia single and multi-flue caps regularly and stock standard sizes on the truck. For custom and odd-dimension work, we fabricate through Famco and handle the measurement, ordering, and installation ourselves. No running around to supply houses, no endless back-and-forth.
If a storm has torn your cap off or water is actively pouring into the firebox, call us at (516) 301-1549 and we’ll work to get a tech out as fast as the schedule allows. In the meantime, we can walk you through temporary steps over the phone to limit water entry until we arrive. We don’t promise a time we can’t keep, but we do answer the phone 24 hours a day.
Every cap and crown job includes a written warranty that names the specific materials, the install date, and exactly what’s covered, tied to the 365-Day Done Right Promise. If the work isn’t right, we make it right. The warranty is in writing before we start, documented when we finish, and we don’t hide behind fine print.
Yes, for the first visit. We need access to the roof and a chance to show you the camera findings before work starts. After that first inspection and repair, future maintenance can often be done without you present, and we’ll send the photo record and written summary by text and email.
