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 been working the Arbutus grid for decades. The compact brick Cape Cods off Shelbourne Road, the post-war ranches along Leeds Avenue, the attached bungalows near Arbutus Middle School - we know these chimneys because we’ve been inside them. Arbutus sits in the Patapsco River watershed corridor where humidity runs higher than inland Maryland suburbs, and that moisture works hard on aging masonry crowns that were never designed to take forty years of freeze-thaw cycling. When your crown cracks or your cap rusts through, water doesn’t just drip into the flue. It finds the hairline fractures in 1950s terra-cotta liners, accelerates spalling brick, and creates the draft problems that send homeowners calling us when the fireplace starts smoking into the living room.
Our Chimney Cap & Crown team handles everything from single-flue cap swaps to full crown rebuilds with Gelco coating on multi-flue stacks. Dispatch and scheduling are coordinated from our Baltimore office, but the crews serving Arbutus live locally and carry the parts these chimneys actually need.
Why Hearthstone Chimney Co. Is Arbutus’s Preferred Chimney Cap & Crown Company
We’ve served communities across Baltimore County for over 42 years, and Arbutus has been part of our route since the beginning. The company was founded in 1984, and we’ve built our reputation one chimney at a time - no franchises, no call centers, no rotating crews who don’t know the neighborhood.
Our reviews from Arbutus customers consistently mention the same things: the technician showed up when promised, explained what was wrong without pushing, and left the work site clean. That’s the K.E.Y.S. code we operate under - Krafted right, Every time, Your home first, Standing behind it. The 90-Day Done Right Promise backs every job in writing with no arguing. If it’s not right, we come back.
Response time to Arbutus is typically three to five business days for standard cap and crown work. We don’t promise same-day dispatch because we won’t book what we can’t deliver. But we do answer the phone with a live person 24 hours a day, 7 days a week - not a voicemail, not a callback queue. When you call (410) 849-6273, someone picks up.
What sets us apart in Arbutus specifically is our familiarity with the shared-stack problem. These 1940s-60s Cape Cods and brick bungalows often have a single masonry stack where a now-removed oil furnace flue still shares the chimney with an active gas water heater. That leftover configuration is far more common in Arbutus than in newer Patapsco-corridor suburbs, and it dictates how we size, seat, and vent a replacement cap. A technician who doesn’t recognize that setup can install a perfectly good cap that still leaves you with draft problems and carbon monoxide risk.
Our Chimney Cap & Crown Services in Arbutus
Cap Installation
New cap installation in Arbutus starts with understanding what your chimney actually vents. For the typical Arbutus Cape Cod with a shared oil-to-gas flue stack, a stock single-flue cap often makes the problem worse by leaving one flue open or creating pressure imbalances between appliances. We measure every flue, check draft patterns with the water heater running and the insert cold, then recommend a cap that keeps each appliance drafting independently. Most new cap installations in Arbutus run $280-$450 for standard stainless steel, with multi-flue configurations starting at $480.

Cap Replacement
Arbutus’s original caps are usually twenty to forty years old by now. Galvanized steel rusts through. Cheap aluminum deforms in wind. We replace them with professional-grade caps from Olympia Chimney, Famco, and Copperfield - materials rated for coastal-influenced humidity, not the dry-climate specs you’ll find at hardware stores. A straight replacement on a standard flue in Arbutus is typically $320-$520. If the flue tile is cracked or the crown underneath has eroded, we’ll document it with photos and explain your options before we proceed.

Crown Repair
The chimney crown is the concrete or mortar wash that seals the top of your masonry stack. In Arbutus, crowns fail faster than in newer suburbs because the Patapsco-corridor humidity keeps masonry perpetually damp, and Baltimore County’s 30-40 annual freeze-thaw events turn hairline cracks into spalling brick within a few seasons. We grind out deteriorated crown material, recast with high-strength concrete formulated for freeze-thaw resistance, and slope it to shed water away from the flue. Crown repair in Arbutus typically runs $480-$780. Severe spalling that has reached the brick course below requires partial rebuild, which we’ll quote after inspection.

Crown Coating
For crowns with early-stage cracking but sound structural integrity, we apply Gelco CrownCoat - a flexible, waterproof membrane that bridges hairline cracks and stops moisture infiltration without the cost of full recasting. This is often the right call for Arbutus homeowners whose crowns show surface crazing but haven’t yet spalled to exposed brick. Crown coating runs $280-$420 and carries the same 90-Day Done Right Promise as our rebuilds. It’s not a substitute for structural repair on a failed crown, but it can add years of service life to sound masonry that just needs protection from Patapsco-corridor rain and humidity.

Multi-Flue Cap
The multi-flue cap is our most-requested solution for Arbutus’s shared-stack chimneys. Instead of capping each flue individually - which can create pressure conflicts when a gas water heater and wood insert share the same stack - a multi-flue cap covers the entire chimney top with a single hood, screened vents sized to each flue’s draft requirement, and a skirt that sheds water beyond the crown perimeter. We size and fabricate these on-site because no two Arbutus chimneys are identical. Multi-flue caps start at $680 and typically run $680-$1,100 depending on stack dimensions and screen specifications.

Custom Cap
For Arbutus homeowners with non-standard flue configurations, ornate brickwork they want to preserve, or specific aesthetic requirements, we fabricate custom caps in copper, stainless steel, or powder-coated aluminum. Custom work starts at $850 and is quoted after measurement and photo documentation. Most custom caps in Arbutus are multi-flue configurations for the shared-stack problem, but we’ve also built them for historic properties and for homeowners who simply want a cap that outlasts the stock options by decades.

Trusted Brands We Service in Arbutus
We don’t use builder-grade substitutes. Our trucks carry professional-grade materials from Olympia Chimney, Famco, and Copperfield - brands that specify their products for humid, freeze-thaw climates like the Patapsco corridor. That means stainless steel caps with proper mill certification, not the thin-gauge imports that rust through in five years. It means Gelco crown coatings with documented flexural strength, not bucket-mix sealers from the hardware store. For Arbutus customers, stocking these parts locally means faster turnaround. Most cap and crown jobs are completed in a single visit because the technician arrives with the right materials already on the truck.
Common Chimney Cap & Crown Problems We See in Arbutus Homes
- Single-flue caps that leave shared stacks open. In dense Arbutus rows where attached properties share wall planes, a single-flue cap on a multi-appliance chimney can leave the gas water heater’s flue unprotected or create pressure imbalances that draw combustion products into the wood-burning side. We regularly find this during inspections on Leeds Avenue and Shelbourne Road properties.
- Oversized, cracked terra-cotta liners under ill-fitting caps. Original 1950s flues were sized for fuel oil or coal appliances. When homeowners retrofit wood-burning inserts without relining, the cap that fit the old flue dimensions now conceals an oversized, cracked liner that lets crown-level moisture and third-degree creosote glaze accumulate undetected.
- Freeze-thaw and humidity destroying crown mortar joints. The Patapsco River watershed keeps ambient moisture high year-round. Combined with Baltimore County’s hard winters, this causes efflorescence, spalling, and joint erosion that homeowners often mistake for a cap leak. The real problem is the crown itself, and a new cap won’t fix it.
- Roof access complications on tight Arbutus lots. Narrow side yards and low-slope rancher roofs make ladder placement tricky on many Arbutus properties. Our crews are equipped with adjustable staging and have worked these streets long enough to know which lots require extended ladders and which have rear alley access that simplifies the approach.

FAQs - Chimney Cap & Crown in Arbutus
A properly sized multi-flue cap can solve many shared-stack draft problems, but only if the underlying flue liner is intact and the crown is structurally sound. We were called to a 1952 brick Cape Cod off Shelbourne Road where the crown had spalled down to exposed brick on the west face and the original terra-cotta flue liner showed hairline cracking after decades of freeze-thaw cycling. Our crew pulled the corroded single-flue cap, ground and recast the chimney crown, coated it with Gelco, and set a custom multi-flue cap sized to keep the wood insert flue and the gas water heater flue drafting independently. The homeowner’s draft complaints stopped, and the new cap now sheds Patapsco-corridor rain off the stack instead of into it. Call (410) 849-6273 and we’ll inspect your configuration before recommending anything.
Three factors specific to Arbutus accelerate crown deterioration: the Patapsco River watershed’s higher ambient humidity keeps masonry damp longer after rain; Baltimore County’s 30-40 annual freeze-thaw events exploit every micro-crack; and the 1940s-60s housing stock was built with mortar mixes and crown construction that were adequate for coal and oil appliances but undersized for modern draft demands. Newer suburbs have PVC or stainless flue systems and crowns built to current codes. Arbutus chimneys are still doing the job with sixty-year-old materials. Annual inspection before heating season catches crown problems before they reach the brick course below. Call (410) 849-6273 to schedule yours.
Yes. Even gas water heaters and furnace flues need protection from rain, debris, and animal intrusion. In Arbutus, an uncapped flue in a shared stack is especially problematic because downdrafts can push combustion products from one appliance into another’s air supply. A proper cap with correct screen sizing prevents blockages without restricting draft. We inspect and cap active flues regardless of fuel type. Call (410) 849-6273 for a free evaluation of your stack configuration.
A Level 2 inspection examines the full interior flue surface with a video camera, checks the crown and masonry for structural integrity, verifies clearances to combustibles, and documents any cracks, gaps, or obstructions that would affect cap selection and sizing. For Arbutus’s shared-stack chimneys, we also verify which appliances vent into which flues and whether the configuration meets current draft standards. You receive photos and a plain-English verdict before any work is proposed. The inspection is included in our cap and crown estimates. Call (410) 849-6273 to book.
Copper and heavy-gauge stainless custom caps outlast stock galvanized or thin-aluminum caps by decades, especially in Arbutus’s humid, salt-influenced climate. The question is whether your chimney’s condition justifies the investment. A custom cap on a failing crown is money wasted; we always repair the crown first. For sound masonry with shared flues or non-standard dimensions, a custom multi-flue cap from Copperfield or Famco is often the most cost-effective long-term solution. We’ll show you the photos and explain both options. Call (410) 849-6273 for an exact quote - estimates are free.
