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.
Fast, Reliable Chimney Cap & Crown Across Ellicott City
Chimney cap and crown work in Ellicott City typically runs $385-$1,950 depending on whether you need a standard stainless cap, a full crown rebuild, or a custom multi-flue setup on a historic stack. Most cap replacements are done in a single visit. Crown repairs take longer when we’re dealing with the granite and soft brick found throughout the lower Historic District, and that’s exactly the kind of work our crews are built for. If you’re off Frederick Road, up in the hillside subdivisions, or down near Main Street, call (980) 580-8641 and we’ll give you a written price before anyone touches your chimney.
We’re Emberly Chimney Cleaners, and we’ve inspected and cleaned more than 38,000 chimneys since 2009. Every one of those jobs started with a written price. Every one ended with a photo record. That’s not a marketing line. It’s Clause 4 of the Haven Standard we’ve operated under since the day we started.
Why Emberly Chimney Cleaners Is Ellicott City’s Preferred Chimney Cap & Crown Company
Ellicott City homeowners don’t have a generic chimney problem, and we don’t do generic chimney work. The valley below Main Street holds some of the oldest continuously standing masonry chimneys in Maryland, original granite and brick stacks from the late 1700s and early 1800s. The hillsides around it hold 1970s-1990s colonials and split-levels with builder-grade caps that wind gusts off the Patapsco Valley knock loose every few years. Both are our daily work.
Our Chimney Cap & Crown technicians arrive with a camera, a moisture meter, and a written estimate pad. They don’t guess. They document. When the camera shows a rusted-shut throat damper off Frederick Road or spalling granite on a Main Street row home, you see the photo. Then you see the written price. Then you decide. That’s the sequence on every job, and Ellicott City homeowners read their three-star reviews everywhere. We know they want evidence, not reassurance. Corrine Halstead built the crew that way.
Response time to Ellicott City is same-week for most cap and crown work. Dispatch coordinates from the brand’s Washington, DC office, but the crews serving Ellicott City work locally and know the difference between a 1790s granite stack and a 1980s builder-grade masonry chimney without being told.
Our Chimney Cap & Crown Services in Ellicott City

Cap Installation
A missing or undersized cap on an Ellicott City chimney means rain falls directly into the flue. In the valley, that rain picks up moisture that’s already concentrated by the Patapsco River, and the result is first-degree creosote turning to third-degree glaze faster than most homeowners realize. We install stainless steel caps sized to your flue, not whatever is on the truck. Olympia Chimney and Gelco are the brands we most often quote for Ellicott City jobs because they hold up to Mid-Atlantic freeze-thaw without warping.

Cap Replacement
Wind gusts coming through the Patapsco Valley loosen builder-grade caps on hillside split-levels all the time. A displaced cap exposes the flue liner to direct rain, and that water runs down into the firebox by the first freeze. We replace the cap, check the liner with a camera, and document the condition in writing. If the old cap was the wrong size from the original build, we don’t just swap it. We measure and install the correct fit.

Crown Repair
The crowns we see in the Historic District crack differently than anything on the surrounding plateau. Original granite and soft historic brick expand and contract with every freeze-thaw cycle, and the 2016 and 2018 floods forced water into mortar joints that never fully dried. That leaves spalling behind the cap, hidden water channels, and rusted dampers. We repair crowns with a Gelco crown coat where the masonry is sound, or rebuild them when the damage runs deep. Either way, you get a written scope before we start.

Crown Coating
A cracked crown doesn’t always need a full rebuild. On many Ellicott City homes, especially 1970s-1990s colonials with builder-grade mortar, a crown coat is the right call. We clean the surface, repair the cracks, and apply a flexible waterproof membrane. Done correctly, it buys a decade or more before a rebuild is necessary. Done incorrectly, it peels in two years. We warranty the work under our 365-Day Done Right Promise.

AfterTrusted Brands We Service in Ellicott City
We stock and install caps and crown materials from Olympia Chimney, Gelco, and Famco because those are the brands that hold up in Ellicott City’s specific conditions. Olympic stainless caps resist the valley’s constant moisture. Gelco crown coatings flex through freeze-thaw cycles instead of cracking. Famco dampers and caps fit the older clay-tile flues we see throughout the Historic District. We keep common sizes staged for Ellicott City jobs so a cap replacement doesn’t turn into a two-week wait for parts.
Common Chimney Cap & Crown Problems We See in Ellicott City Homes

- Flood-compromised mortar joints spalling behind the cap. The 2016 and 2018 floods forced water into ash pits, fireboxes, and mortar joints throughout the lower Historic District. That water is still working its way out, and it shows up as cracked crowns and displaced caps years later.
- Builder-grade caps knocked loose by Patapsco Valley wind gusts. Hillside subdivisions off Frederick Road and Route 40 sit in a wind channel. Caps installed in the 1980s and 1990s with cheap hardware are the ones we find sitting sideways or hanging off the flue.
- Rusted-shut throat dampers from valley moisture. The Patapsco River concentrates moisture around the lower town. Dampers in those chimneys rust shut faster than anywhere else in Howard County, and they need to be addressed before the first fire, not after smoke backs up into the living room.
- Ceiling stains that trace back to crown cracks and failed flashing. Water follows the path of least resistance. When it finds a cracked crown on a hillside colonial, it travels down the brick, corrodes the flashing, and stains the ceiling two rooms away. By the time you see the stain, the crown has been leaking for months.

FAQs - Chimney Cap & Crown in Ellicott City

Crowns in the lower Historic District are built from original granite and soft historic brick that absorb water and expand through every Mid-Atlantic freeze-thaw cycle. The 2016 and 2018 floods saturated those masonry cores, and seven-plus years of cycling has widened mortar joints and cracked crowns at a rate the surrounding plateau doesn’t see. A crown crack in that part of Ellicott City isn’t cosmetic. It’s a water channel into the firebox. Call (980) 580-8641 for a camera inspection and written assessment.
Yes, and we’ve traced that exact path more times than we can count. A wind gust knocks the cap sideways, rain falls straight into the flue, water pools in the smoke chamber, and it works through the brick into the ceiling cavity two rooms away. The stain is the last symptom, not the first. If you’ve got a stain and a cap that looks off, check both before the first fire. Our photo record will show you exactly where the water is entering.
Floodwater forced into mortar joints doesn’t dry out cleanly. It carries silt and salts into the masonry, which then spalls behind the cap and weakens the crown from underneath. Homeowners in the lower Historic District often discover the damage years later as a cracked crown, a displaced cap, or a rusted-shut damper. If your chimney sat in floodwater, get a Level 2 camera inspection before any cleaning work. Nothing gets recommended without photos you can see.
Look at the cap first. Is it level, or is it listing? Any visible gap between the cap and the crown means water got in during the last storm. Next, check the crown from the ground or a ladder if you’re comfortable. Cracks wider than a quarter inch need attention before you burn. Then open the damper. If it doesn’t move freely, moisture has been sitting in the throat. On a hillside colonial off Frederick Road, our tech once found a cracked crown and a rusted-shut damper after heavy valley moisture. The crown got a Gelco coat, the cap got replaced with an Olympia stainless unit, and the flashing got repaired. The ceiling stain disappeared within a week. Call (980) 580-8641 to schedule a seasonal check before you light the first fire.
No, and here’s why that’s a bad idea on an 18th- or early 19th-century stack. Paint doesn’t fill the crack or stop the water. It seals moisture inside, and then freeze-thaw cycles spall the masonry from the inside out. On historic granite and soft brick, the right repair is either a flexible Gelco crown coat or a full rebuild, depending on how deep the damage runs. Painting makes the crack harder to see and the eventual repair more expensive. We’ll document the crack with a camera, give you a written price for the correct fix, and stand behind it with our 365-Day Done Right Promise.
