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.

Why Emberly Chimney Cleaners Is Union’s Preferred Chimney Cap & Crown Company
Union homeowners call us because we show them the problem before we ask for a dime. Our camera-scan inspection goes down the flue and across the crown, and you see exactly what we see: hairline cracks, spalled mortar, mesh that’s blown out, or a cap that’s corroded past saving. Corrine Halstead has built this company on one rule that’s now Clause 1 of the Haven Standard: a written price, written scope, and written warranty before anyone picks up a tool. No exceptions, every job, and it’s been that way since 2009 across more than 38,000 chimneys inspected and cleaned.
We know Union’s housing stock because we’re in it every week. The 1950s ranches along Burnet Avenue, the 1960s colonials near Morris Avenue, the older pre-war homes in Connecticut Farms: each has a different chimney profile and a different failure pattern. When we quote a crown repair in Union, we quote it for the actual masonry in front of us, not a generic template. Dispatch is coordinated from our New York City office; the crews that arrive at your door are Union-local, uniformed, background-checked, and texted to you before they pull up.
Our 365-Day Done Right Promise applies to every cap and crown job in Union. If it’s not done right, we make it right. That’s stamped on every job under the Haven Standard, alongside the documented photo record that’s been standard since 2009: Clause 4, archive included on every visit.
Our Chimney Cap & Crown Services in Union
Every Chimney Cap & Crown job in Union starts with the same question: what does the camera show? Here’s what we do once we know.
Cap Installation
A new cap on a Union chimney usually runs $380-$780 installed, depending on flue size and whether you need a standard single-flue cap or something wider. We stock stainless steel caps from Copperfield and Famco specifically because Union’s moisture patterns eat galvanised steel in five to eight years. Stainless holds. We’ll show you the difference on the camera before you choose.
Cap Replacement
If your existing cap is rusted through, missing its spark-arrestor mesh, or letting rain pour straight down the flue, replacement is the clean fix. In Union, we most often replace galvanised caps on 1950s and 60s chimneys where the mesh has pitted and blown out. Cost is $420-$850 for most single-flue replacements, including removal, disposal, and the new cap.
Crown Repair
Union’s freeze-thaw cycles are brutal on poured concrete crowns. Hairline cracks open, water gets in, freezes, and widens the crack. We repair crowns by grinding back spalled edges and applying a flexible crown coat that moves with the masonry instead of fighting it. Typical crown repair in Union runs $550-$1,450 depending on how much of the crown needs to be rebuilt. The alternative is waiting until the flue liner is exposed to direct rain, and that’s a much bigger bill.
Crown Coating
Crown coating is the preventive option: a flexible, water-tight membrane over the crown’s surface that seals existing micro-cracks and prevents new ones from opening. For Union homes at the freeze-thaw convergence, this is often the single best dollar-for-dollar protection you can buy. Most crown coatings in Union run $450-$1,100. We use HeatShield and Gelco materials because they’re designed for exactly this repair cycle.
Multi-Flue Cap and Custom Cap
Colonials, split-levels, and some larger ranches in Union often have multi-flue chimneys that standard caps don’t fit well. We measure, fabricate, and install custom stainless caps sized to your exact flue configuration. Cost for a custom or multi-flue cap in Union is $780-$1,450. If you’re in the Vauxhall section with a 1960s colonial, this is probably your situation.

BeforeAfterTrusted Brands We Service in Union
We work with materials from Copperfield, Famco, and HeatShield, and we keep common cap sizes and crown coating products stocked locally for Union jobs. That means when we show up to a ranch off Burnet Avenue and find a 13×13 flue with a corroded cap, we’re not ordering parts and coming back next week. We carry what Union’s housing stock actually needs. All materials are procured through Haven’s buying network, which is how we keep customer pricing honest while still using components built to handle Atlantic moisture and hard winters.
Common Chimney Cap & Crown Problems We See in Union Homes
- Galvanised cap corrosion within 5-8 years. Union sits where Atlantic moisture pushes inland, carrying chloride-laden air that pits galvanised steel quickly. The mesh fails first, then embers and animals get into the flue.
- Crown spalling from repeated freeze-thaw. Union gets more 32°F crossings than nearby inland towns like Springfield, because Atlantic moisture and continental cold collide here. Capillary cracks open and close dozens of times each winter, and over a few seasons the crown surface starts flaking off in chunks.
- Gas-converted flues with oversized clay liners. The 1940s-1960s housing in Union was built for wood or coal, then converted to gas. An oversized clay liner produces acidic condensation that wicks up through the crown, staining it and degrading the bond between masonry and cap. We see this constantly on Burnet Avenue and Morris Avenue ranches.
- Original poured crowns with shallow drip edges. The 1950s and 60s homes in Union often have crowns with tooled drip edges that hold water instead of shedding it. That standing water is exactly what freezes, expands, and pops the crown surface loose.

FAQs - Chimney Cap & Crown in Union
Union sits at the convergence of Atlantic moisture and continental cold air, which means the township experiences more freeze-thaw cycles per winter than towns like Springfield or Elizabeth. Each time the temperature crosses 32°F, water that’s seeped into capillary cracks in the crown freezes and expands, widening those cracks. Over a single winter, that can happen dozens of times. The result is accelerated crown spalling that you simply don’t see at the same rate in more inland or more coastal towns. If your Union crown is flaking or chalking, call (980) 580-8641 for a camera inspection and a written price.
Yes, and here’s the specific reason: Burnet Avenue and the surrounding 1950s ranches sit squarely in the path of Atlantic moisture that carries chloride-laden air inland from the coast. Galvanised caps in that zone typically corrode within five to eight years, and the mesh is usually the first component to fail. Stainless steel from Copperfield or Famco holds up far longer in that environment. It’s a higher upfront cost, but you’re replacing a five-year cap with a fifteen-to-twenty-year cap. We’ll show you the corrosion on camera before you decide.
Yes, indirectly. Union’s gas-converted flues often retain original clay tile liners sized for solid fuel, which are oversized for a gas appliance. That oversizing creates acidic condensation, and when the crown is cracked and letting in rain on top of that, you get a damp, cool flue that doesn’t vent properly. Soot and creosote-like deposits can accumulate even in a gas system. The crown damage is the missing piece in a lot of those diagnoses. We’ll camera the full flue and show you exactly what’s happening.
Every two years is the minimum we recommend for Union homes, given the freeze-thaw exposure and the age of the housing stock. If you have a galvanised cap, a poured crown from the 1950s or 60s, or a gas-converted flue, an annual camera scan is worth it. The inspection takes about 40 minutes, includes the full photo record under Haven Standard Clause 4, and gives you a written report with prices for any recommended work. You’re not obligated to do the work with us, but you’ll know exactly where you stand. Call (980) 580-8641 to book.
Most likely, yes. The 1960s colonials in Vauxhall and around Union typically have chimneys with two or three flue openings in an irregular configuration, and standard single-flue caps don’t cover them properly. A custom stainless cap sized to your exact flue layout costs $780-$1,450 in Union, and it’s the difference between a cap that actually keeps rain and animals out versus one that just sits on top. We measure on site, fabricate to spec, and install the same day in most cases. Call (980) 580-8641 and we’ll confirm what you need with the camera.
