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 Hearthstone Chimney Co. Is Randallstown’s Preferred Chimney Cap & Crown Company
We’ve been working on Randallstown chimneys long enough to recognize the block-by-block patterns. This is a town where the housing stock was built in a concentrated wave from the 1950s through the 1970s, and those masonry stacks are aging on the same schedule. Our Chimney Cap & Crown team has replaced crowns on Winands Road capes, installed multi-flue caps on split-levels near Church Lane, and repaired spalled brick on colonials off Liberty Road.
Our reputation here is built on showing, not telling. Every inspection includes a Level-2 camera examination with photos the homeowner can see and a plain-English verdict. No camera evidence, no recommendation. The 90-Day Done Right Promise backs every job in writing, with no arguing. Calls are answered by a live person 24 hours a day, 7 days a week, and our technicians complete most jobs in a single visit with no-hassle upfront pricing.
Dispatch and scheduling are coordinated from our Baltimore office, but our crews serve Randallstown locally and know the area’s specific chimney failure patterns. We’ve seen what humid summers and freeze-thaw winters do to 60-year-old mortar crowns. We plan to be serving this community for decades more, and we act accordingly.
Our Chimney Cap & Crown Services in Randallstown
Cap Installation
New cap installation in Randallstown typically costs $180-$420 for a standard single-flue galvanized or stainless steel cap, with copper and custom profiles running higher. Most Randallstown homes built in the 1960s and 70s never had proper caps installed, or the originals were lost to wind or rust decades ago. An uncapped flue is an open invitation for rain, squirrels, and nesting birds. We size every cap to the specific flue opening and recommend stainless steel or copper for durability against our freeze-thaw cycles.

Cap Replacement
Cap replacement runs $150-$380 in Randallstown, though corroded or improperly installed caps often reveal deeper crown damage underneath. We see this constantly on Liberty Road-era homes where a cheap big-box cap was slapped on a deteriorating crown and called good enough. We pull the old cap, inspect the crown surface with the camera, and only quote what the stack actually needs. If the crown is sound, we install a properly fitted replacement with correct clearances and screening.

Crown Repair
Crown repair is where Randallstown’s synchronized housing age really shows. Full crown rebuilds typically run $480-$890, with minor crack sealing and coating at the lower end. Original poured crowns on 1950s-70s capes and split-levels spall and crumble from repeated freeze-thaw crossings each November through March. We form and pour new crowns with proper overhang, drip edge, and slope to shed water away from the brick below. Every rebuild gets photo documentation before, during, and after.

Crown Coating
Crown coating with professional-grade flexible sealant runs $280-$450 for most Randallstown chimneys, suitable for crowns with surface cracking but intact structural integrity. This is not a fix for severely spalled or separated crowns, and we’ll show you the camera footage to prove which category yours falls into. We use materials rated for Mid-Atlantic temperature swings, not the thin brush-on products that fail after one hard winter.

Multi-Flue Cap
Multi-flue caps are essential for many Randallstown homes, especially the brick colonials and split-levels with two or three flues sharing one chimney stack. A single-flue cap leaves gaps where rain and animal entry reach the damper and smoke chamber. Custom multi-flue caps typically run $340-$680 depending on dimensions and material. We measure on-site and fabricate to fit all flue openings with a single protective cover, properly screened and vented.

Custom Cap
Custom caps for Randallstown’s varied chimney profiles, decorative pots, or non-standard flue arrangements start around $420 and run to $1,200+ for large copper fabrications. We work with Gelco and Olympia Chimney products, measured and fitted to your specific stack. No guesswork, no gaps, no “close enough.”

Common Chimney Cap & Crown Problems We See in Randallstown Homes
- Spalled crowns from freeze-thaw cycling. Randallstown’s temperatures cross 32°F repeatedly each winter, and water trapped in porous crown mortar expands and fractures with every cycle. By March, the crown surface is crumbling and the brick below is absorbing moisture.
- Gas insert retrofits eating through clay liners. Homeowners who converted wood fireplaces to gas inserts in the 1990s and 2000s often discover their clay flue tiles deteriorated from acidic condensing flue gases. The cap and crown may look intact while the liner behind them is failing, which is why we camera-inspect every stack.
- Wrong-size caps leaving gaps on multi-flue stacks. Oversized single-flue caps on old multi-flue chimneys leave exposed openings where rain pours onto the smoke chamber and damper. Humid Randallstown summers let moss and water infiltration work into hairline cracks opened by winter freezing.
- Missing or rusted original caps. Many 1960s Randallstown homes never had proper caps, or the originals were thin galvanized steel that rusted through decades ago. The flue has been open to the elements ever since, accelerating deterioration of the crown and interior masonry.

FAQs - Chimney Cap & Crown in Randallstown
Randallstown developed as a post-WWII suburb in a concentrated burst from the 1950s through the 1970s, so nearly every masonry chimney on the same block is hitting the 50-70 year mark simultaneously. Clay flue tile liners from that era are cracking, mortar crowns are spalling, and brick joints are failing en masse across the same generation of homes. This synchronized aging creates a local demand pattern far more concentrated here than in suburbs with mixed construction timelines. Call (443) 998-2617 for a free camera inspection to see where your stack stands.
You need a Level-2 camera inspection first, because gas insert retrofits into oversized wood-burning fireboxes commonly produced acidic condensing flue gases that eat through clay flue tile never rated for low-temperature operation. Many 1990s-2000s conversions in Randallstown were never relined to code. The cap and crown may appear fine while the liner behind them is deteriorated. We camera-inspect, show you the photos, and only then discuss whether cap, crown, or liner work is needed. Call (443) 998-2617 to schedule.
If your chimney has two or more flue openings sharing one stack, a single-flue cap leaves gaps where rain and animals enter the unprotected flues. Many Randallstown brick colonials and split-levels from the 1960s and 70s have multi-flue construction that was never properly capped. We measure all openings on-site and fabricate a single cover that protects every flue. Call (443) 998-2617 and we’ll sort it out during the inspection.
A damaged crown lets water into the masonry, which degrades the liner and smoke chamber and can restrict draft, but the more immediate risk is structural deterioration and potential carbon monoxide leakage through cracked flue walls. Draft problems in Randallstown’s older chimneys more often trace to liner damage from gas insert retrofits or deteriorated parging inside the firebox. We camera-inspect to distinguish crown issues from liner issues before recommending any work. Call (443) 998-2617 for an exact diagnosis.
We show you camera evidence before quoting anything. On a split-level off Liberty Road, we pulled a rusted multi-flue cap off a 1962 brick chimney and found the clay crown spalled down to the brick course, with two of three flues already weeping water into the smoke chamber below. We set a poured crown with a proper overhang and drip edge, then installed a custom multi-flue cap sized to all three openings. No camera evidence, no recommendation. The 90-Day Done Right Promise is in writing, with no arguing. Call (443) 998-2617 for an inspection where you see what we see.
