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.

Hanover’s chimneys are not like the ones you see in older Maryland towns. They’re factory-built, zero-clearance systems wrapped in metal chases, and they fail in patterns we can read from the street. Corrine Halstead has built our team around one principle: show the customer the evidence before asking them to spend a dime. That means a camera down the flue, photos of every corroded cap and cracked crown, and a written scope with a written warranty before any work starts.
Why Emberly Chimney Cleaners Is Hanover’s Preferred Chimney Cap & Crown Company
We have worked on hundreds of chimneys in Chimney Cap & Crown in Hanover neighborhoods, from the 2000s-era townhome rows off Dorchester Boulevard to the larger single-family subdivisions near Route 100. What our techs see over and over in Hanover is a specific failure pattern: builder-grade galvanized chase covers rusting through around the 15-year mark, painted steel caps losing their rain skirts, and water working its way down into fireboxes that were never built for infiltration. That local repeat exposure means we know what to look for before we even climb the ladder.
Every job gets a document trail. Clause 4 of the Haven Standard requires a photo record on every visit, and we have kept that practice running since 2009. When our tech tells you a chase cover is done, you’ll see the rust holes in the photos, not just hear the words. And if something isn’t done right, the 365-Day Done Right Promise means we make it right.
Our Chimney Cap & Crown Services in Hanover
Cap Replacement
The majority of caps we replace in Hanover are the original builder-grade painted steel units installed during the Arundel Mills construction boom. After 15-20 years of Chesapeake airshed humidity, those caps lose their rain skirt, corrode at the mount, or simply rust through. We size a correct replacement cap, typically stainless or copper, and install it with the proper fasteners for your specific flue configuration. Most cap replacements in Hanover are done in a single visit.
Cap Installation
Some Hanover homes never got a proper cap, or the original was removed during a previous repair and never refit. A missing cap leaves the flue open to rain, birds, and debris, and in Hanover’s townhome rows where every unit shares the same original spec, that missing cap is an invitation for water to pool in the firebox. We install multi-flue caps, single-flue caps, and custom caps sized to the exact flue tile dimensions we measure on site.
Crown Repair
The concrete crown at the top of a chimney is the first line of defense against water intrusion. In Hanover, freeze-thaw cycles through Maryland winters open hairline cracks in poured concrete crowns, especially on prefab chases where the crown meets the metal. Those cracks let standing water seep down into the chase and accelerate interior rust on the flue liner. We repair crowns with proper cementitious sealant, rebuild badly spalled crowns, and apply crown coating where the existing concrete is sound enough to save.
Crown Coating
A crown that is still structurally intact but showing surface cracks and minor pitting can often be preserved with a flexible crown coating. This is a more affordable option than full crown replacement and makes sense for many Hanover homes where the crown is 12-18 years old and starting to show its age. The coating seals hairline fractures and keeps them from opening wider through the next freeze-thaw season. We will tell you plainly when coating is enough and when the crown needs a full rebuild, and we’ll show you the close-up photos either way.

BeforeAfterTrusted Brands We Service in Hanover
We install and service caps and crowns from Gelco, Famco, and Copperfield, selected through our buying network to keep Hanover prices reasonable without cutting material quality. We know which Gelco caps fit the standard prefab chases in Hanover’s townhome communities, and we keep common sizes and mounting hardware on our service vehicles so we’re not sending a tech back across Route 100 for a second trip. If your existing cap is a specific brand, we match the replacement, not just whatever is left on the truck.
Common Chimney Cap & Crown Problems We See in Hanover Homes
- Rusted-through chase covers on 2000s-era prefab chases. The builder-grade galvanized covers installed during the construction boom have a roughly 15-year corrosion lifespan, and Hanover neighborhoods are cycling into failure together. Even a small rust hole lets rain pour directly down the flue and into the firebox, warping refractory panels and rusting the damper assembly.
- Missing rain skirts on painted steel caps. Hanover townhome rows share identical spec caps from the original build, and when one loses its rain skirt to corrosion, the whole row is usually on the same clock. A cap without a proper rain skirt leaves the flue open to rain and birds.
- Freeze-thaw cracking in poured concrete chase crowns. Hanover’s position in the Chesapeake airshed means persistent humidity, and our winters climb above and below freezing all season. Water seeps into hairline crown cracks overnight, freezes, expands, and widens the crack. Standing water then sits against the metal chase and accelerates rust on the flue liner inside.
- Water damage reaching the firebox and refractory panels. On a 2004-era townhome off Dorchester Boulevard near Arundel Mills, we traced a second-floor ceiling stain back to a rusted-through chase cover on the prefab chimney. The original 18-year-old galvanized cover had failed, the Gelco cap above it had lost its rain skirt, and water was running down through a dual-flue chase to the firebox. We pulled the original cover, found the flaking cap, and replaced both, then applied a crown sealant at the flue tile joints to stop the recurring water entry.

FAQs - Chimney Cap & Crown in Hanover
Yes, and the reason is not cosmetic. A galvanized cap that still looks mostly intact from the ground can be corroding from the inside at the mount points and rain skirt, where standing water and Chesapeake humidity concentrate. The caps installed on Hanover townhomes during the 2000s construction boom have a predictable 15-20 year lifespan. Our camera inspection will show you the actual condition, not a guess. Call (980) 580-8641 and we’ll put the photos in your hand.
Every two years is the honest answer for Hanover’s climate. The chase cover is the flat metal lid at the top of your prefab chimney, and it is the single most common point of failure on any 2000s-era system in this area. If yours is approaching 15 years old, make it annual. The inspection itself is not expensive, and catching a rust-through before water reaches the firebox saves you a much larger repair bill later.
Most of the early-2000s prefab units in Hanover were built with Gelco caps and galvanized chase covers from the original builder supply chain, along with Famco or Copperfield components on a smaller portion of homes. Our service vehicles carry common Gelco replacement parts for the standard chase sizes in this area, and we source Copperfield and Famco components through our network when a brand-specific match is needed. We’ll tell you the exact part number we’re quoting and show you the existing component on camera.
Yes. When a chase cover rusts through, water runs straight down the inside of the metal chase and pools at the firebox. Refractory panels are not waterproof, and repeated wetting causes them to crumble and spall, leaving the metal firebox shell exposed to corrosion. You may not see the damage until the panels are already failing. If you have rust staining on the exterior of the chase or any ceiling staining near the fireplace, get it inspected now. Call (980) 580-8641 for a free estimate.
Yes, if the two flues exit through the same chase cover at the top, a multi-flue cap is the correct install. Trying to place two separate single-flue caps side by side leaves gaps around the chase opening that let rain, birds, and debris in. A properly sized multi-flue cap seals the entire opening and extends the rain protection across both flues. We’ll measure the chase opening and flue positions on site and quote the correct cap in writing before any work starts.
