Expert Chimney Repair & Masonry
From minor cracks to full structural rebuilds—Baltimore Chimneys restores safety and beauty to your home's chimney system.
Restore Your Chimney's Structural Integrity
Maryland's freeze-thaw cycles wreak havoc on masonry. Over time, mortar joints deteriorate, bricks spall, and chimney crowns crack—allowing water to penetrate your home's interior. Left unattended, these “minor” issues can lead to thousands of dollars in structural damage.
Our team specializes in professional masonry restoration using traditional techniques combined with modern waterproofing solutions. We match historic mortar colors and ensure every repair is durable and aesthetically pleasing.

Common Chimney Repairs We Handle
We repair every part of your chimney system—inside and out—using materials and methods proven to last in Baltimore's climate.
Flashing Repair & Waterproofing
Chimney leaks rank among the most frequent problems in Maryland homes, thanks to heavy rainfall, freeze-thaw cycles, and snowmelt. Flashing—the metal seal where your chimney meets the roof—is most often the culprit when water intrudes.
We also apply industrial-grade breathable waterproofing sealants to your brick and mortar to stop water penetration while allowing moisture vapor to escape, preventing internal spalling.
- Step & counter-flashing replacement
- Cricket installation for wide chimneys
- ChimneySaver waterproofing application
Tuckpointing & Mortar Restoration
Mortar is the softer element intentionally designed to absorb the stress of expansion and contraction—protecting your bricks. When mortar crumbles, water infiltrates and speeds up brick deterioration dramatically.
Our tuckpointing specialists carefully remove deteriorated mortar to a precise depth, then pack in matching mortar to restore both the structural bond and the visual appeal of historic Baltimore brick.
- Color-matched mortar for historic homes
- Hand tools for precise joint cutting
- Full chimney or targeted spot repair
Crown Repair & Cap Installation
The chimney crown is the cement slab at the very top that directs rainwater away from the flue. Cracked crowns are one of the leading causes of water damage in older Baltimore homes.
We repair or rebuild crowns using high-quality cement—and can add a premium stainless steel, copper, or aluminum chimney cap to protect against rain, animals, debris, and downdrafts.
- Crack sealing with elastomeric crown coat
- Full crown rebuild if beyond repair
- Stainless, copper & custom cap installs
Firebox & Full Chimney Rebuilds
If your fireplace is original to your Baltimore home and showing serious deterioration, we can fully rebuild it from the foundation up. Our specialists restore everything to like-new condition while prioritizing structural safety.
We also rebuild interior fireboxes—replacing damaged firebrick and refractory mortar to protect from the extreme heat of an active fire.
- Full chimney stack rebuilds
- Firebox firebrick replacement
- Liner installation included in rebuild
