Rain, snow, heat, wind, and ice. Over time, these elements wear down bricks, mortar, flashing, and even the chimney crown. Exterior chimney repair is essential to maintain structural safety and prevent leaks, drafts, or even collapse.

Damage to the outside of your chimney often starts small and gets worse with time. Visual inspections can reveal early warning signs,especially after storms or winter freeze-thaw cycles.
Catching these signs early can save you money and extend your chimney’s lifespan.

















The bricks and mortar that make up your chimney’s exterior naturally wear down with age. Rain and moisture cause the mortar to weaken, which leads to shifting bricks or open gaps. Tuckpointing and brick replacement are common repair solutions.
These repairs restore both function and appearance.

At the top of the chimney, the crown (concrete surface) and cap (metal cover) serve as your first line of defense. Cracks or deterioration in either of these can allow water to seep into the bricks below.
Repairing these components is a priority in any full exterior chimney restoration.

Flashing is the metal barrier where your chimney meets the roof. When this fails, water can seep into your attic or walls. In addition, applying a breathable waterproofing seal to your chimney’s surface can greatly reduce future damage.
These upgrades protect your home’s interior and exterior simultaneously.
Look for cracks, missing mortar, leaning structure, or water stains. Annual inspections can catch problems early.
Tuckpointing involves removing damaged mortar and replacing it to strengthen the chimney and prevent water leaks.
Small jobs like caulking or sealing may be DIY-friendly, but brickwork, flashing, and crown repairs should be done by professionals.
Basic mortar repairs start around $300–$800. Full masonry restoration or crown rebuilds can range from $1,000 to $3,000+.
