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.

We know Catonsville chimneys. The brick colonials and foursquares built between the 1920s and 1960s, the mature oaks dropping debris into flues, the freeze-thaw cycles at 400 feet of elevation that crack old crowns. Our Chimney Cap & Crown crews work these streets year-round, and we bring a camera down every flue before recommending anything.
Why Emberly Chimney Cleaners Is Catonsville’s Preferred Chimney Cap & Crown Company
Catonsville homeowners tend to research first and call second. That’s exactly how we work. Every job starts with a camera-scan inspection (NFPA 211 Level 2), and you walk away with photos, a written price, a written scope, and a written warranty. Clause 1 of the Haven Standard means you always have it in writing before anyone touches your chimney.
This matters on older Catonsville homes. A standard single-flue cap rarely fits the twin or multi-flue masonry chimneys common on 1940s colonials. We stock custom and multi-flue cap options from Copperfield and Famco, so we’re not forcing an off-the-shelf cap onto a chimney it wasn’t built for. Our technicians are background-checked and uniformed, and Corrine Halstead oversees every job that leaves our shop. When we say a cap will clear your draft problem, you’ll be looking at the crown photos yourself.
We also bring a Free Second Opinion on any written estimate. If another company quoted you a crown rebuild or a relining job, bring us the quote. We’ll inspect and tell you whether that work is actually needed. On more than one Frederick Road colonial we’ve found a cracked crown that looked catastrophic but was repairable at a fraction of the quote.
Our Chimney Cap & Crown Services in Catonsville
Cap Installation
A properly sized cap keeps Catonsville’s oak leaves, twigs, and acorn mast out of your flue. For single-flue masonry chimneys we typically install stainless steel caps from Famco, which hold up to decades of wet Maryland weather. For a 1920s brick home near Spring Grove, the right cap also keeps rain from pooling in the original clay tile liner, where freeze-thaw cycles turn moisture into cracks.
Cap Replacement
When a cap has rusted through or was never sized correctly in the first place, we replace it. Catonsville houses that were converted from coal heat to gas often have oversized flues with mismatched caps. That’s not a cosmetic issue. The gap lets rain and pests into the flue, and Baltimore County inspectors flag it during real-estate transactions. We measure the flue, not the old cap, and order the correct fit.
Crown Repair
The crown is the concrete slab that seals the top of the chimney. It’s not the cap. On Catonsville’s 400-500 foot elevation, repeated freeze-thaw cycles crack old poured crowns within a decade or two. Water seeps into the clay tile liners below, causes spalling on the exterior brick, and eventually demands a full rebuild. We patch cracks, overlay with a proper crown coating, or pour a new crown with a bond break when the original has failed. We’ll show you the camera footage either way.
Crown Coating
For crowns that are still structurally sound but starting to show hairline cracks, we apply a flexible crown coating that bridges minor movement through the seasons. It’s a mid-cost intervention that extends the life of an older Catonsville crown by years. We use materials sourced through our buying network specifically to keep the price on the honest side of $600 for most single-chimney homes.

We work with materials from Copperfield, Famco, and DuraFlex on Chimney Cap & Crown in Catonsville jobs. Copperfield multi-flue caps come up often on the twin-flue brick chimneys you see along Edmondson Avenue and through the historic streets off Frederick Road. Famco stainless caps are our default for single flues. When a liner question comes up during a crown repair, DuraFlex liners are what we recommend and install. We keep common sizes in local stock so a Catonsville job doesn’t stall waiting on a backorder.
Common Chimney Cap & Crown Problems We See in Catonsville Homes
- Leaf and twig debris packing under unmeshed caps. Catonsville’s dense oak canopy drops organic material directly into flues. An unmeshed or missing cap lets debris build until draft reverses and smoke pushes back into multi-fireplace homes. We clear it and fit a meshed cap sized to the flue.
- Freeze-thaw cracked crowns on older brick chimneys. At Catonsville’s elevation, water that found its way into hairline cracks freezes, expands, and widens the crack. A decade of that and the crown is shed water into the flue. Catching it early means a coating instead of a pour.
- Coal-era flues with missing or mismatched caps after gas conversion. Many 1920s-1950s Catonsville chimneys were designed for coal. When a gas appliance was attached, the oversized flue was often left with the original masonry crown and no cap, or a cap that doesn’t fit. Rain, squirrels, and leaves enter an unlined flue that was never meant to carry gas exhaust. That’s a code flag during home sales and a relining trigger.
- Spalling brick from water migration through failed crowns. Once a crown fails, water travels down inside the chimney and pushes through the mortar joints, flaking the exterior brick faces. On solid-masonry Catonsville brick homes, the exterior damage is the first visible sign of a crown that failed years earlier.

FAQs - Chimney Cap & Crown in Catonsville
Every year, before burning season. Catonsville’s freeze-thaw cycles at 400-500 feet elevation crack older poured crowns faster than in areas with more stable temperatures. The annual check is a camera pass, not a guess. If you see spalling brick or a damp chimney breast inside the house, call us at (980) 580-8641 and we’ll inspect it.
Because many 1920s-1960s brick homes in Catonsville were built with multi-flue masonry chimneys, either for multiple fireplaces or for coal heat later converted to gas. A standard single-flue cap doesn’t span two or three flues. We measure the crown, note the flue layout, and when needed order a custom Copperfield multi-flue cap that spans the entire crown so both flues stay clear and dry.
You’ll see hairline cracks running across the concrete surface, often with a slight depression where water pools. Sometimes the crack isn’t visible from the ground at all until we’re on the roof with the camera. The first sign from below is usually spalling brick faces or a damp spot on the chimney breast after heavy rain. Call (980) 580-8641 for a camera inspection before the crack becomes a rebuild.
No. Gas flues still move hot exhaust up a chimney that’s exposed to Catonsville weather. A cracked crown lets water into the clay tile liner, and over time that liner deteriorates and sends pieces into the flue. More importantly, a gas conversion on a coal-era chimney often means an oversized flue and a cap that was never fitted. Annual inspection catches it before a Baltimore County code issue during a home sale catches you.
The original masonry crown was left in place when the coal flue was adapted for gas, and no properly sized cap was added. The oversized flue draws rain and debris into the chimney, and the old crown, already decades old, cracks under Catonsville’s freeze-thaw cycles. Water then migrates into the smoke chamber. We repair the crown, fit a correct cap, and if the liner is compromised, quote a relining in writing before any work begins. Call (980) 580-8641 for a free estimate.
