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 Randallstown’s Preferred Chimney Cap & Crown Company
Randallstown’s housing stock has a problem most national inspection checklists skip entirely. The brick ranchers and split-levels along Liberty Road, Winands Road, and Old Court Road were built between 1955 and 1975 with single-wythe brick chimneys and clay tile liners. Those liners are now 50 to 70 years old. When homeowners switched from oil to natural gas, many of the dual-use flues that once served both fireplace and furnace were simply abandoned. Left uncapped. Left open. That’s the job we see most often in Randallstown, and it’s why we’ve spent years documenting what happens to those flues before and after we seal them.
Corrine Halstead leads our crew. Under the Haven Standard, every job we do in Randallstown includes a camera-scan inspection, a written price before work begins, and a documented photo record when we’re done. That’s Clause 4, and it’s been our default since 2009. We’ve inspected and cleaned more than 38,000 chimneys in that time. Each one got a written price before work started. No exceptions.
We coordinate dispatch from our Baltimore office, but the crews working in Randallstown live and work in Baltimore County. They know what a 1960s brick rancher chimney looks like after 60 freeze-thaw seasons, and they know what questions to ask before quoting a crown rebuild or a custom cap.
Our Chimney Cap & Crown Services in Randallstown
Cap Installation
A correctly sized cap does more than keep rain out. On Randallstown homes with abandoned dual-use flues, a cap is what finally closes the passage that’s been funneling moisture, debris, and squirrels into your smoke chamber. We measure the flue tile, not the exterior brick, and install caps from Famco and Copperfield sized to the actual clay tile opening. For a 1960s home with an 8×12 flue, that usually means a multi-flue cap rather than a universal fit.
Cap Replacement
If your current cap is rusted through, blown off by a storm, or simply missing from a furnace flue you didn’t know existed, replacement is straightforward but sizing matters. A cap that’s too small chokes draft on the fireplace flue. A cap that’s too large rattles and lets wind-driven rain in around the edges. We match the replacement to the flue, not to whatever was there before. Many Randallstown homes we visit have caps that were installed for the wrong flue type years ago.
Crown Repair
The crown is the concrete slab that seals the top of the chimney structure. On Randallstown’s single-wythe brick chimneys, crown spalling is the clearest warning sign of water intrusion. Freeze-thaw cycling through Baltimore County winters forces water into small cracks, where it freezes and expands, popping the surface layer off the crown. We repair crowns with Gelco products, and on homes where the crown has failed entirely, we rebuild it with proper overhang and a drip edge so water sheds away from the brick rather than into it.
Crown Coating
For crowns that are intact but porous, we apply a flexible crown coating that bridges minor cracking and prevents water absorption. This is common on younger Randallstown chimneys and on crowns we’ve already repaired once. It’s a shorter, less expensive job than a full rebuild, but it’s only appropriate when the underlying crown is still structurally sound. We’ll tell you if it’s not. The camera inspection we run before quoting shows us what’s actually there, and we show it to you.
Custom & Multi-Flue Caps
Many 1960s Randallstown homes were built with one flue serving both fireplace and oil furnace. After gas conversion, that dual-use flue was often abandoned without recapping or relining. We build custom multi-flue caps for these chimneys, covering both flues with one properly damped unit. The goal is to close the passage against rain, animals, and downdraft while still venting whichever appliance still uses the flue. We fabricate from Copperfield and Famco components and have the cap built to the exact outside dimensions of your flue tile array.

Common Chimney Cap & Crown Problems We See in Randallstown Homes
- Spalling crowns from freeze-thaw cycling. Baltimore County temperatures cross the 32°F threshold multiple times per week in winter, which forces water into microscopic crown cracks, freezes it, and pops the surface. On 50 to 70-year-old crowns, this is routine.
- Uncapped abandoned flues from oil-to-gas conversion. The single most common finding in Randallstown. A flue that once served both fireplace and furnace is left open after gas conversion, channeling rain, snowmelt, and animals directly into the firebox. Rusted dampers and interior staining are the usual result.
- Missing or undersized caps on dual-use flues. Squirrels and birds nest in the upper flue and smoke chamber, blocking draft and creating a fire hazard. The nest material itself is combustible, and the blockage sends smoke back into the living space.
- Eroded mortar joints escalating crown failure. Once water penetrates behind the single-wythe brick, every freeze-thaw cycle widens the joint. That erosion accelerates crown cracking, and the two problems feed each other until the top of the chimney is structurally compromised.

FAQs - Chimney Cap & Crown in Randallstown
Yes, if the flue is open. Many 1960s Randallstown homes were built with one flue serving both the fireplace and the oil furnace, and after gas conversion that flue was often abandoned without a cap. Even if no one ever lit a fire in the fireplace, the open flue still funnels rain, snowmelt, and animals into the smoke chamber and firebox. We find rusted dampers, rotted damper frames, and interior staining in homes where the fireplace was never used once. The cap isn’t about using the fireplace; it’s about closing a hole in your roof system. Call (980) 580-8641 for a camera inspection and we’ll show you what’s actually open.
Freeze-thaw cycling is the usual cause. Baltimore County winters push temperatures above and below freezing repeatedly, and any water that seeps into the crown’s surface expands when it freezes, cracking the top layer away. If the crown was poured without an overhang or drip edge, water runs down the brick face instead of shedding away, which keeps the crown wet and worsens the cracking. Our crown repairs use a Gelco product with a proper drip edge, and for chimneys that keep failing, we often recommend a full rebuild rather than a third or fourth patch. Call (980) 580-8641 and we’ll tell you honestly whether your crown needs a patch, a coating, or a rebuild.
Yes. On split-levels where the furnace flue was abandoned after gas conversion, we can cap that flue independently while leaving the fireplace flue functional. The measurement is taken at the clay tile, not at the exterior brick, which matters because many Randallstown split-levels have different flue tile sizes on the furnace side versus the fireplace side. We’ll cap whichever flues are no longer venting anything and leave the active flues properly sized and dampered. Call (980) 580-8641 for a written estimate with the exact cap configuration.
For most brick ranchers with two flues side by side, a multi-flue cap that covers both is the better choice over two separate single-flue caps. Multi-flue caps seal the gap between the tiles and provide a cleaner profile, and they’re easier to secure on older chimneys where the mortar between flues has already started to erode. We use Copperfield and Famco multi-flue caps sized to the actual flue array. If one flue is still venting a gas furnace, we’ll match the cap’s mesh spacing and height to that flue’s venting requirements. Call (980) 580-8641 and we’ll confirm the right configuration for your roofline.
Look for spalling: pieces of concrete on the roof or in the gutter below the chimney, a pitted or flaking surface on the crown itself, or white efflorescence streaking down the brick below the crown line. Inside, you may see water staining on the fireplace walls, a rusted damper, or musty smells from the firebox after rain. Any of these means the crown is no longer sealing the top of the chimney structure. Our camera-scan inspection in Randallstown includes photos from the flue interior, which shows us whether water has been entering and how far down it’s traveled. Call (980) 580-8641 - the inspection is part of every estimate.
One More Thing About Randallstown Chimneys Most Pages Never Mention
The 1960s dual-use flue is the unexamined variable in Randallstown cap and crown failures. Homes built along Liberty Road, Winands Road, and Old Court Road during Baltimore County’s 1950s to 1970s suburban expansion were engineered to vent oil-burning furnaces, not the clean-burning gas furnaces that replaced them. When the furnace switched, the flue was often simply closed off at the appliance level and never touched at the top. That open passage sits there for decades, collecting water every time it rains, hosting squirrels every spring, and gradually washing mortar out of the smoke chamber and firebox. Our crew capped and crowned a mid-century brick rancher along the Liberty Road corridor where the original clay tile flue had been abandoned after a gas conversion. We installed a Copperfield multi-flue cap over the 8×12 clay tile and rebuilt the crown with a Gelco product, after first sealing spalling mortar joints that had opened during freeze-thaw cycles. Moisture was running down into the firebox and onto the damper; the homeowner had no idea because the fireplace had never been used. That’s the kind of problem that doesn’t announce itself until the damper rusts through or the ceiling stains. We document it, we show you the photos, and we write down exactly what it will cost to fix. That’s how we work in Randallstown.
