What Causes Chimney Damage

Water Damage

The primary enemy of chimneys. Water enters through cracks, failed flashing, and porous masonry, causing widespread deterioration.

Freeze-Thaw Cycles

Water freezes and expands in cracks, forcing them wider. Each cycle progressively destroys mortar and brick.

Thermal Cycling

Repeated heating and cooling stresses materials, particularly clay tile liners, causing cracks over years of use.

Age and Settling

All materials deteriorate over time. Mortar has a finite lifespan. Professional maintenance extends longevity dramatically.

Poor Construction

Chimneys built with inadequate materials or improper techniques develop problems earlier than well-built chimneys.

Water is the primary enemy of chimneys. Most chimney repairs are ultimately water damage repairs.

When Chimney Repair is Urgent

Some problems can wait for scheduled service. Others need immediate attention.

Urgent

Chimney leaning, active water leaks into living spaces, structural cracks, smoke entering rooms, post-fire damage

Soon

Deteriorating mortar, cracked crown, minor flashing gaps, spalling bricks, missing cap

Scheduled

Cosmetic mortar work, preventive waterproofing, cap upgrade, minor brick repairs

When in doubt, professional inspection determines urgency accurately.
