Our Chimney Cap & Crown Services in Garrison
Cap Installation
New cap installation in Garrison typically serves two purposes: keeping water out and keeping wildlife out. On the wooded half-acre lots common through 21117, we install caps that stand up to heavy leaf debris and, critically, prevent chimney swifts from establishing nests. These migratory birds are federally protected; once they’re in, you can’t legally disturb them between May and October. A properly fitted cap installed before spring eliminates that headache entirely. We size caps precisely to your flue count and dimensions, using materials from Famco and Copperfield that won’t rust through in five Baltimore County winters.

Cap Replacement
Garrison’s older caps - the builder-grade galvanized models common on 1970s colonials - corrode predictably after decades of exposure. We replace them with stainless steel or copper caps that match your home’s look and outlast the original by decades. Because we stock parts for Garrison’s common flue configurations, most replacements happen same-day. Our Chimney Cleaning & Sweep in Garrison often reveals cap deterioration homeowners hadn’t noticed; we can coordinate both services in one visit.

Crown Repair
The concrete crown at your chimney’s top takes the brunt of Baltimore County’s freeze-thaw punishment. In Garrison’s 1960s-1980s housing stock, these crowns were often poured too thin or without proper overhang and drip edge, directing water straight into the masonry below. We rebuild crowns with proper slope and thickness, using professional-grade crown sealants that flex with temperature swings instead of cracking again. For chimneys with underlying flue liner damage - common here after 40-plus years of thermal cycling - we also provide Chimney Liner & Rebuild in Garrison to address the full system.

Crown Coating
Not every cracked crown needs full replacement. When the structural concrete is sound but the surface has weathered, we apply elastomeric crown coating formulated for chimney exposure. This buys years of protection at lower cost, particularly valuable on Garrison cape cods and split-levels where the chimney crown is harder to access and full rebuild labor runs higher. We assess honestly: if coating won’t last, we’ll tell you straight and quote the rebuild.

Common Chimney Cap & Crown Problems We See in Garrison Homes
- Crown cracking from freeze-thaw cycling. Baltimore County winters swing repeatedly across 32°F, and Garrison’s older masonry crowns absorb moisture that expands and contracts until the concrete fractures. Once cracked, water funnels directly into the chimney structure, accelerating deterioration of mortar joints and clay flue liners below.
- Missing or rusted caps on original 1970s installations. Many Garrison colonials and split-levels still carry their original galvanized caps, now rusted through or blown off in storms. A missing cap leaves the flue open to rain, leaves, and nesting animals - we’ve found squirrels, raccoons, and chimney swifts occupying flues that haven’t seen a cap in years.
- Improperly sized caps from prior repairs. Homeowners sometimes install caps that don’t fully cover the flue opening or lack proper mesh screening. On Garrison’s wooded lots, this partial coverage still allows leaf debris accumulation and doesn’t prevent swift nesting. We measure twice and fit once.
- Spalling and deterioration from tree cover moisture. Garrison’s heavily wooded residential terrain creates microclimates of persistent humidity. Chimneys shaded by mature oaks and maples stay damp longer after rain, accelerating crown surface breakdown and rust on metal components. Proper cap and crown work includes assessing these site-specific conditions.
Pricing for Chimney Cap & Crown in Garrison, MD
A standard stainless steel cap installation in Garrison typically runs $280-$450, depending on flue count and whether custom sizing is needed.
