Fast, Reliable Chimney Cap & Crown Across Lansdowne
Chimney cap and crown repair in Lansdowne typically runs $280-$650 for most jobs, and our Chimney Cap & Crown team can usually be on your street within the hour. We’ve been working the 21227 ZIP since 1984, so we know the difference between a Lansdowne rowhome chimney that shares a party wall and a standalone semi-detached stack. That matters because the repair approach changes, and getting it wrong means water in your neighbor’s wall too.

Why Hearthstone Chimney Co. Is Lansdowne’s Preferred Chimney Cap & Crown Company
We’ve capped and crowned chimneys along Lansdowne Road, Hollins Ferry Road, and the older streets off Washington Boulevard for over four decades. Homeowners here remember when we repaired their parents’ chimney in 1992. That kind of continuity means something in a town where houses pass through generations.
Our Level-2 camera inspections end with photos you can see and a plain-English verdict. No jargon, no scare tactics. In Lansdowne’s 70-80-year-old brick housing stock, we regularly find crown deterioration that started five years before the homeowner noticed a water stain. Catching it early saves the flue, the liner, and the wall repair bill.
Most Lansdowne calls reach us in under an hour. Our technicians are background-checked, uniformed, and carry professional-grade materials from Gelco, Olympia Chimney, and Famco on every truck. Most jobs finish in a single visit with no-hassle upfront pricing. The number on the estimate is the number on the invoice.
Every repair is backed by our 90-Day Done Right Promise in writing. If it’s not right, we make it right. No paperwork, no arguing.
Our Chimney Cap & Crown Services in Lansdowne
Cap Installation
New cap installation in Lansdowne runs $280-$450 for a standard single-flue galvanized or stainless steel unit. We size for the actual flue, not guess from the ground. In Lansdowne’s dense rowhome blocks, we often install multi-flue caps that protect two or more flues under one cover, critical for the shared chimney stacks common to twin homes off Hammonds Ferry Road. Our caps come from Gelco and Olympia Chimney, built to survive Baltimore County’s freeze-thaw cycle without warping or rust-through.
Cap Replacement
Cap replacement in Lansdowne typically costs $320-$520, depending on whether the flue tile underneath has deteriorated. The old caps on these mid-century chimneys were often cheap galvanized units that lasted maybe eight years. We replace with stainless steel or copper options that handle the acidic condensation from modern gas appliances far better. If your current cap is rattling in the wind off the Patapsco River valley, it’s already past due.
Crown Repair
Crown repair in Lansdowne averages $380-$650. The concrete crown at your chimney’s top takes the worst of every winter, and in 21227’s housing stock, original crowns were often poured too thin or without proper overhang. We cut back to sound concrete, form a proper slope, and pour a new crown with adequate drip edge so water sheds clear of the brick below. Done right, and we stand behind it.
Crown Coating
Crown coating with HeatShield or similar professional-grade flexible sealant runs $280-$420 in Lansdowne. This is a sound option when the crown has minor cracking but hasn’t spalled through to the flue. We don’t coat over structural failure, and we’ll tell you straight if coating would be throwing good money after bad. Our Chimney Liner & Rebuild in Lansdowne team coordinates with us when crown damage has already compromised the liner below.
Multi-Flue Cap
Multi-flue caps for Lansdowne’s shared-wall and twin-home chimneys range from $520-$890 installed. One cap covers two or more flues with proper clearance and screening. This matters enormously in 21227, where a single chimney stack may vent a furnace for one unit and a water heater for the adjacent unit. A poorly fitted multi-flue cap creates downdraft problems that put both households at risk. We measure twice, fabricate once, and stand behind the fit.
Custom Cap
Custom caps for unusual flue configurations or historic preservation requirements in Lansdowne start around $680 and range to $1,200 or more for copper with custom screening. We’ve fabricated caps for the older homes near the Lansdowne Library and for properties where standard sizes simply don’t fit the original masonry. Custom work takes longer, but the result outlasts three off-the-shelf replacements.

Trusted Brands We Service in Lansdowne
We stock professional-grade caps, crowns, and flashing materials from Gelco, Olympia Chimney, and Famco on every Lansdowne truck. These aren’t builder-grade substitutes from the hardware store. Gelco’s stainless multi-flue caps carry a lifetime warranty against corrosion. Olympia Chimney’s pre-formed crown forms give us a clean pour in weather that turns fast off the Chesapeake. Famco’s screening keeps out the starlings and squirrels that nest in Lansdowne’s uncapped flues every spring. Because we carry inventory, most Lansdowne jobs don’t wait on parts. We also handle Chimney Cleaning & Sweep in Lansdowne using the same professional standards.
Common Chimney Cap & Crown Problems We See in Lansdowne Homes
- Freeze-thaw spalling on original crowns. Baltimore County’s winter pattern, dozens of hard freezes followed by sudden thaws, destroys the porous concrete crowns poured in the 1950s and 1960s. We see this every February along Lansdowne’s older streets, where crown cracks have widened enough to let water pool and refreeze against the flue tile.
- Missing or rusted caps on converted coal chimneys. The original flue openings for coal furnaces were larger than modern gas appliance flues, and many Lansdowne homeowners never had a properly sized cap installed after conversion. Rain falls straight onto the oversized clay liner, accelerating the corrosive condensate damage that already plagues these flues.
- Shared-stack downdraft between attached units. In Lansdowne’s semi-detached twins, one neighbor’s new high-efficiency furnace can create negative pressure that backdrafts the adjacent unit’s water heater. A properly sized multi-flue cap with adequate height and screening often resolves this, but only if someone measures both flues and the stack geometry together.
- Crown wash failures hiding liner damage below. Previous owners sometimes slathered roofing tar or cheap sealant over a crumbling crown. It looks fixed from the ground, but water still migrates through pinholes and runs down the flue. Our camera inspection catches this before the liner collapses.

FAQs - Chimney Cap & Crown in Lansdowne
Most Lansdowne calls reach us in under an hour during business hours, and our live-answer desk schedules next-day appointments for non-urgent work. If water is actively entering your flue or your cap is dangling loose after a windstorm, we prioritize. Call (844) 803-1545 and a real person will find the next available slot.
Yes. We work the full 21227 ZIP, from the older brick rowhomes along Washington Boulevard and Hollins Ferry Road to the semi-detached twins off Lansdowne Road and the streets near the library. Ladder access on narrow rowhome lots is routine for us, not an excuse to charge extra.
Yes. Our phones are staffed by a live person 24 hours a day, 7 days a week. If a storm tears your cap off at midnight or you discover active water intrusion during a holiday weekend, we answer and dispatch. Not every after-hours call requires immediate dispatch, but you’ll talk to someone who can assess and schedule, not a voicemail queue.
Lansdowne pricing is comparable to nearby Arbutus and Linthicum, sometimes slightly less than Elkridge where larger detached homes require more material. The bigger variable is housing type: a standard rowhome cap installation in Lansdowne often runs lower than a sprawling multi-flue job in a newer suburb because we can ladder-access efficiently and the flue count is predictable. We’ll give you an exact number after inspection.
Every repair is covered by our 90-Day Done Right Promise in writing. If the cap leaks, the crown cracks, or anything we touched fails due to our workmanship, we return and fix it at no charge. No paperwork to dig up, no argument about whose fault it was. Materials carry their own manufacturer warranties, Gelco’s lifetime corrosion warranty for example. We honor both, and we document every job with photos so there’s never a question about what was done.
