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.

AfterFast, Reliable Chimney Cap & Crown Across Arnold
Chimney cap and crown repair in Arnold typically runs $280-$890 depending on whether you’re replacing a rusted cap, coating a cracked crown, or rebuilding from the flue up. Most Arnold homeowners on the Broadneck Peninsula need service sooner than inland Anne Arundel County because salt-laden air off the Magothy River and Chesapeake Bay accelerates metal corrosion and masonry spalling. If you’re seeing rust flakes in your fireplace or hairline cracks spreading across your chimney crown, call (443) 464-2560. Our Chimney Cap & Crown team dispatches to Arnold from our Baltimore office, and we complete most jobs in a single visit with no-hassle upfront pricing.
Why Hearthstone Chimney Co. Is Arnold’s Preferred Chimney Cap & Crown Company
We’ve been answering the phone with a live person for over 42 years, and that hasn’t changed. When you call (443) 464-2560, day or night, you’ll talk to someone who can book your Arnold appointment and answer questions about what to expect.
Our technicians are background-checked and uniformed, and they carry professional-grade materials from HeatShield, Gelco, and Olympia Chimney on every truck. That means no waiting for parts when we find your galvanized cap rusted through or your mortar crown spalled from another winter of freeze-thaw.
Every inspection ends with photos you can see and a plain-English verdict. Nothing gets recommended without camera evidence, and we’ll tell you straight when work can safely wait. Our 90-Day Done Right Promise covers every job in writing, no arguing. If it’s not right, we come back.
We know Arnold’s housing stock because we’ve worked it for decades. The 1960s-through-1980s colonials and split-levels from Ulmstead Estates to Shore Acres Road share the same brick-and-mortar chimneys with original clay tile flue liners now hitting 40-60 years old. That age plus salt-air exposure is a specific combination we see nowhere else in Anne Arundel County.
Our Chimney Cap & Crown Services in Arnold
Cap Installation & Replacement
Galvanized caps on Arnold homes near the Magothy River often rust through at the seams and mounting screws within just a few years. We were called to a split-level off Shore Acres Road where the homeowner had a two-year-old galvanized cap that had already rusted through, letting water run down the flue. We replaced it with a stainless multi-flue cap and recoated a crumbling crown that had spalled from salt-air freeze-thaw. Switching to stainless stopped the recurring corrosion the homeowner had been paying to patch every couple of seasons. For Arnold installations, we default to stainless steel or copper caps from Gelco and Olympia Chimney that withstand maritime humidity. A standard cap replacement in Arnold runs $280-$450; multi-flue or custom configurations range $450-$750.
Crown Repair & Coating
The mortar crown is the concrete or mortar slab that seals the top of your chimney between the flue tiles and the brick edge. On Arnold’s 1960s-80s brick chimneys, these crowns crumble and spall as maritime humidity keeps masonry damp through freeze-thaw cycles, cracking and exposing the flue top. Crown coating with HeatShield applies a flexible, waterproof membrane over sound-but-cracked concrete, typically $340-$520 in Arnold. If the crown has deteriorated past ¼-inch cracks or the mortar is actively falling away, partial rebuild is the honest call. We document the difference with camera photos so you can see what we see.
Multi-Flue & Custom Cap Installation
Many Arnold colonials and split-levels have multiple fireplaces or a fireplace plus a furnace flue sharing one chimney chase. A single cap won’t cover this safely. We fabricate and install multi-flue caps measured to your chase dimensions, with proper clearance and spark arrestor mesh, using stainless or copper from Famco and Olympia Chimney. Custom caps for non-standard chase sizes or historic homes in older Arnold subdivisions run $650-$890 installed. The investment pays back quickly when you consider what repeated water intrusion costs in flue liner damage and interior drywall repair.
Flashing Repair & Replacement
Flashing around the chimney chase corrodes and pulls away from coastal roofing, opening leak paths into the smoke chamber and attic during nor’easters. In Arnold, we see this most often on homes within a half-mile of open water where salt air attacks the metal step-flashing and counter-flashing. Repair runs $320-$580 depending on roof pitch and how far the leak has traveled. We use copper or lead-coated copper for Arnold installations, never aluminum that won’t survive five years on the Broadneck Peninsula.

Trusted Brands We Service in Arnold
We stock professional-grade caps, crowns, and flashing materials from HeatShield, Gelco, Olympia Chimney, and Famco on our service trucks. These are the brands specified by chimney professionals nationwide, not builder-grade substitutes you’ll find at big-box retailers. For Arnold customers, this means same-day completion on most cap replacements and crown coatings without waiting for parts to ship. When your galvanized cap has rusted through during a January freeze or your crown cracks open before burning season, that parts availability matters. We’ve used these brands long enough to know which stainless cap profiles shed driving rain best on low-pitch Arnold roofs, and which crown coatings flex enough to survive another decade of Maryland freeze-thaw.
Common Chimney Cap & Crown Problems We See in Arnold Homes
- Galvanized caps rust through at seams within 2-4 years. The salt air off the Magothy and Bay penetrates the zinc coating at cut edges and screw holes. Rust flakes drop into the flue, staining fireboxes and accelerating liner corrosion. Stainless replacement is the only lasting fix on the Broadneck Peninsula.
- Mortar crowns spall and crack from persistent dampness. Arnold’s maritime humidity keeps chimney tops damp through shoulder seasons, so freeze-thaw damage penetrates deeper each winter than in drier inland climates. By the time you see interior ceiling stains, water has already compromised the flue liner.
- Flashing corrodes and separates from shingles. Salt air attacks the galvanized or aluminum flashing original to many Arnold homes, and the gap opens during wind-driven rain. We find active leaks into attics during routine inspections that homeowners never suspected.
- Clay flue liners crack from thermal shock and water infiltration. Original liners in Arnold’s 1960s-80s housing stock are now at the age where freeze-thaw and cap/crown failure combine to cause vertical cracking. A cracked liner is a carbon monoxide and chimney fire risk that demands Level-2 camera inspection.

Arnold’s salt-air exposure means we recommend stainless components over galvanized for any cap or flashing work. The upfront cost difference is $80-$150 on a standard cap, but the replacement cycle stretches from 3-4 years to 15-20. Crown coating versus rebuild is the other major cost variable. We won’t coat a crown that’s structurally unsound; the photos from our Level-2 inspection show you exactly which category you’re in. Every estimate is free, with the number on the estimate matching the number on the invoice. Call (443) 464-2560 for exact pricing on your chimney.

FAQs - Chimney Cap & Crown in Arnold
Salt-laden maritime humidity accelerates galvanic corrosion on metal chimney caps, with galvanized steel showing seam rust within 2-4 years on Broadneck Peninsula homes versus 10-15 years inland. The zinc coating on galvanized caps breaks down at cut edges and fastener holes first, and the constant dampness prevents the protective patina from forming. We specify stainless steel or copper caps for all Arnold installations because they form a passive chromium oxide layer that salt air cannot penetrate. Call (443) 464-2560 to check whether your current cap is galvanized and what replacement would cost.
Every 12 months if you’re within a half-mile of the Magothy River or Chesapeake Bay, even with light use. Arnold’s salt-air humidity accelerates cap, crown, and liner deterioration whether you light fires or not, and the freeze-thaw cycle damages damp masonry every winter. Homeowners who burn only occasionally in October and March often have heavier creosote condensation than heavy burners because the flue never reaches sustained temperatures that dry the system. Our $89 Seasonal Tune-Up includes the Level-2 camera inspection and photo report. Call (443) 464-2560 to schedule.
The crown is the mortar or concrete slab that forms the top surface of your chimney, sealing between the flue tiles and the brick edge. The cap is the metal cover that sits above the crown, protecting the flue opening from rain, animals, and debris while allowing smoke to exit. In Arnold, we often find both failing simultaneously because water that gets past a rusted cap saturates the crown, and a cracked crown lets water attack the cap mounting hardware from below. Repairing one without addressing the other wastes your money. Our inspection documents both with photos so you understand the full condition.
Crown coating is sufficient if the cracks are hairline to ⅛-inch, the concrete surface is still bonded to the brick below, and there’s no active spalling or exposed aggregate. We apply HeatShield crown coating, a flexible waterproof membrane that bridges small cracks and prevents water penetration. If the crown has deteriorated past ¼-inch cracks, shows widespread spalling, or sounds hollow when tapped, partial or full rebuild is the honest recommendation. We show you the camera photos and explain which category your crown falls into before any work begins. Coating runs $340-$520 in Arnold; rebuilds start at $580.
Yes. We measure your chase on site and fabricate multi-flue caps in stainless or copper with proper clearance heights and spark arrestor mesh for each flue. Many Arnold colonials and split-levels have a fireplace flue plus a furnace or water heater flue in the same chase, and a single cap creates dangerous downdraft and drafting problems. Custom caps for non-standard dimensions or historic homes run $650-$890 installed. Most jobs complete in one visit because we carry the measuring tools and common stainless profiles on every truck.
