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’ve spent 42 years watching water do what water does to masonry in Ellicott City’s freeze-thaw climate. A missing cap or cracked crown isn’t a cosmetic issue. It’s an open invitation for moisture to seep into your flue, erode mortar joints, and turn a $300 repair into a $3,000 rebuild. We’ve rebuilt too many chimneys in neighborhoods like Dunloggin and Valley Mede that could have been saved with a proper cap ten years earlier. Our Level-2 camera inspection shows you exactly what’s happening up there, in photos you can see, with a plain-English verdict on what needs doing now and what can wait.
What Our Chimney Cap & Crown Service Includes
Cap Installation
A chimney cap is a metal cover that sits atop your flue, blocking rain, animals, and debris while letting smoke escape. In Ellicott City, where mature oak and maple canopies drop leaves straight into uncapped flues every autumn, we’ve pulled out squirrel nests the size of basketballs from chimneys in the Historic District. We install caps from Gelco and Copperfield in stainless steel or black powder-coated finishes, measured and fitted to your exact flue dimensions. Most installations take under an hour, and we bring a range of sizes so we’re not making a second trip.

Cap Replacement
Caps rust, blow off in windstorms, or get damaged by falling branches - we’ve replaced caps in Ellicott City after every major weather event since 1984. A rusted cap stains your chimney face with orange streaks and eventually fails to keep water out. We remove the old unit, inspect the flue tile for hidden damage, and install a replacement that matches or exceeds the original specification. If your cap came from a big-box store and lasted three seasons, we’ll show you the difference professional-grade materials make.

Crown Repair
The crown is the concrete slab that seals the top of your chimney where the flue tiles emerge. Cracks in the crown are the single most common source of chimney leaks we find in Ellicott City’s older homes, especially in neighborhoods like Font Hill and Worthington where chimneys date to the 1960s and 70s. We grind out cracked or spalling concrete, apply a bonding agent, and pour new crown material sloped to shed water. A proper crown overhangs the brick by at least two inches - anything less, and water runs straight down the face of your chimney.

Crown Coating
For crowns with minor cracking that hasn’t yet compromised the structure, we apply a flexible elastomeric coating from HeatShield or similar professional-grade systems. This isn’t paint - it’s a waterproof membrane that bridges hairline cracks and flexes with temperature swings. In Ellicott City, where winter nights hit the teens and summer afternoons push ninety, that flexibility matters. We pressure-wash the crown first, repair any voids, and apply two coats. Done right, it adds ten to fifteen years of life to a sound crown at a fraction of rebuild cost.

Multi-Flue Cap
Homes with multiple fireplaces or a fireplace and a furnace sharing one chimney need a multi-flue cap - a single cover that protects two or more flue openings. We’ve installed hundreds in Ellicott City’s larger colonials and split-levels, particularly in areas like Centennial and St. John’s Lane where homes were built with multiple hearths. These caps are custom-measured on site and fabricated from heavier-gauge stainless steel to span the wider opening. The right multi-flue cap also improves draft by creating a unified chimney top that resists wind-induced down-drafting.

Custom Cap
Some chimneys need what no catalog carries: an oversized flue, an unusual shape, or a homeowner who wants copper that will patina to match their historic Ellicott City home. We measure, sketch, and spec custom caps fabricated to order from Copperfield and other specialty suppliers. A custom copper cap on a Federal-style home in the Old Ellicott City historic district isn’t vanity - it’s protecting a structure that has stood for two centuries. We document the existing conditions, photograph every angle, and deliver a cap that fits like it was made for your chimney, because it was.

Brands We Service for Chimney Cap & Crown
We’ve installed and serviced Gelco caps since their earliest stainless models, and we stock their standard sizes on every truck. Their mesh design holds up to Ellicott City’s squirrel population better than lighter hardware-store alternatives, and we’ve replaced enough failed off-brand caps to know the difference. Hearthstone Chimney Co. also works extensively with Copperfield for custom and specialty applications, including copper and black galvanized finishes that hold their appearance through Maryland’s humid summers and salted winter roads.
DuraFlex and HeatShield materials factor into our crown repair and coating work - DuraFlex for flue relining when crown damage has allowed water to compromise the flue interior, HeatShield for their cerfractory crown coating systems that bond to concrete at high temperatures. Whether you have Gelco, Copperfield, DuraFlex, HeatShield, or any other make on your chimney, we can service it, repair it, or replace it with something that will last.
Signs You Need Chimney Cap & Crown Right Now
- Water stains on your ceiling near the chimney. This means moisture is already inside the flue, running down the liner, and finding its way into your living space. In Ellicott City’s older homes with plaster ceilings, that stain is often the last warning before the plaster gives way. We find the entry point with our camera inspection and stop it at the source.
- Rust streaks running down the chimney face. Orange or brown stains on brick or siding below the crown mean your cap is rusting through or missing entirely. Every rain event washes more rust onto your masonry, and eventually the flue itself begins to deteriorate. We’ve replaced flue liners in Ellicott City homes where rust went unaddressed for two seasons.
- Chunks of concrete on the roof or ground near the chimney. Spalling crown concrete is a structural failure. The crown’s job is to shed water away from the flue opening; once it breaks apart, water pours directly into the chimney core. In freeze-thaw cycles like Ellicott City’s late winter, a compromised crown can destroy a chimney in a single season.
- Animals or nesting debris visible in the flue. Birds, squirrels, and raccoons enter uncapped chimneys readily, and their nests block airflow and create fire hazards. We’ve removed nests from chimneys in every Ellicott City neighborhood from Chatham to Long Gate, and we always inspect for damage the animals caused on their way in.
- White efflorescence on exterior brick. That chalky white deposit is minerals left behind when water evaporates out of brick - it means water is getting in and moving through the masonry. The source is often a cracked crown or missing cap, and the underlying damage progresses whether you see it or not.
Our Chimney Cap & Crown Process - Step by Step
- 1
Schedule and confirm. Call (410) 305-7884 and a live person answers, 24 hours a day. We’ll find a window that works for you, confirm the appointment by text, and send a photo of your technician before they arrive. No four-hour windows, no waiting around.
- 2
Level-2 camera inspection. Before we quote any work, we run a camera up your flue to document the condition of the liner, the smoke chamber, and the area where the flue meets the crown. You see the photos on a tablet while we’re still on the ladder. If the crown is cracked, we show you the crack. If the cap is missing, you see the open flue. No surprises, no selling what you don’t need.
- 3
Plain-English verdict and upfront pricing. We explain what we found, what needs doing now, and what can wait. Then we give you a written estimate with one number - the number on the invoice. Our $50 off any repair over $250 applies automatically, and our 5% senior and veteran discount is always available.
- 4
Professional installation or repair. Our background-checked, uniformed technicians carry the materials to complete most cap and crown jobs in a single visit. We use professional-grade products from Olympia Chimney, Famco, Gelco, and Copperfield - no substitutes. Crown work includes proper slope, overhang, and expansion joints. Cap installations include secure mounting that withstands Ellicott City’s wind exposure.
- 5
Documentation, cleanup, and guarantee. We photograph the completed work, leave your property cleaner than we found it, and provide a written receipt with our 90-Day Done Right Promise. If anything isn’t right, we come back. No paperwork to file, no arguing, no charge. That’s the Keystone Standard we’ve operated by since 1984.
How Much Does Chimney Cap & Crown Cost in Ellicott City?
See our Chimney Cap & Crown cost guide: a standard single-flue cap installation in Ellicott City runs $180-$340, depending on flue size and whether we need to remove a damaged existing cap. Crown coating for minor cracking typically costs $400-$650. Full crown rebuilds, common in homes built before 1990 in neighborhoods like Dunloggin and Centennial, range from $800-$1,200 depending on chimney width and accessibility. Multi-flue caps start around $450 and scale with span and material choice. Custom copper or specialty caps are priced individually after measurement.
Several factors move these numbers. Chimney height affects labor - a two-story colonial on a hillside lot in Ellicott City takes longer to access safely than a rancher in Valley Mede. Crown condition matters: a crown with structural cracking requires full rebuild, while surface crazing may qualify for coating. Flue damage discovered during inspection adds to the scope, though we never proceed beyond the agreed estimate without your approval.
The best way to avoid overpaying is to address problems before water destroys underlying masonry. A $300 cap installation prevents the $3,000 rebuild we’ve done too many times in Ellicott City. Our free estimate includes the camera inspection and written verdict - no charge, no obligation. We’ll also tell you honestly when work can safely wait a season, which is more often than you might expect.

Frequently Asked Questions - Chimney Cap & Crown in Ellicott City
A chimney cap is a metal cover that sits over your flue opening to block rain, animals, and debris. The crown is the concrete slab that tops your chimney masonry and sheds water away from the flue. You need both because the cap protects the flue interior while the crown protects the chimney structure itself; one without the other leaves your chimney vulnerable to water damage. In Ellicott City’s climate, where freeze-thaw cycles begin in late fall and run through early spring, both components are essential to chimney longevity.
Most cap installations and replacements take 45 minutes to 90 minutes. Crown coating requires two to three hours including surface preparation and cure time. Full crown rebuilds typically take four to six hours and may require a return visit if weather interferes with curing. Our technicians arrive with materials for most common jobs, so we’re not stretching the work across multiple days. Call (410) 305-7884 for a free estimate and we’ll give you a specific time frame for your chimney.
Standard cap installation runs $180-$340, crown coating $400-$650, and full crown rebuilds $800-$1,200 in the Ellicott City market. Multi-flue caps and custom work are priced individually. The final cost depends on chimney height, accessibility, and whether underlying flue damage is found during inspection. We provide upfront pricing before any work begins, and our $50 off any repair over $250 applies automatically. Call (410) 305-7884 for an exact quote - estimates are free.
Yes. We install, repair, and replace caps from Gelco, Copperfield, and all other professional-grade manufacturers. We stock common Gelco sizes and can order specialty Copperfield custom caps with typical lead times of one to two weeks. Our technicians are trained on the specific mounting requirements and warranty terms for each brand we carry. Whether your existing cap is one of these brands or a hardware-store special that failed prematurely, we can recommend and install the right replacement.
We answer calls 24 hours a day, 7 days a week, and we prioritize storm damage that leaves your flue open to water intrusion. A missing cap after a windstorm or lightning-damaged crown can allow significant water entry within hours, so we aim to secure the chimney same-day or next-day when weather permits. For non-emergency scheduling, we typically book within a week. Call (410) 305-7884 anytime - a live person will answer and triage your situation.
All work is covered by our 90-Day Done Right Promise in writing: if it’s not right, we come back and make it right, no arguing, no paperwork. Manufacturer warranties vary by product - Gelco and Copperfield stainless caps carry lifetime warranties against corrosion, while crown coating systems typically warranty against failure for ten years when applied by a certified technician. We register all manufacturer warranties on your behalf and keep copies in our files so you’re never hunting for paperwork.
Clear a path to your fireplace and move any fragile items from the mantel. If possible, park vehicles to allow truck access to the chimney side of the house. We bring drop cloths, shoe covers, and our own ladders, so you don’t need to provide equipment. For crown work, we may need to run a hose for mixing concrete, so accessible outdoor water is helpful. We’ll confirm any specific needs when we schedule, and our technician will call 30 minutes before arrival.
