Signs Your Chimney Needs Repair

Catching chimney problems early saves money — especially in Portland, where rain accelerates masonry damage. Here are the signs homeowners should not ignore.

Exterior Warning Signs

• Cracked or crumbling crown — water enters the masonry from the top
• Loose or missing bricks — structural weakness and water paths
• Soft, sandy mortar joints — tuckpointing is usually needed
• Spalling (flaking) brick faces — freeze-thaw damage from trapped moisture
• Rusted chase cover or cap — common leak source on prefab chimneys
• White chalky residue (efflorescence) — mineral salts from moisture moving through brick

Interior Warning Signs

• Water stains on ceilings or walls near the fireplace
• Smoke entering the room instead of drafting up
• Musty smells after rain
• Pieces of brick, mortar, or creosote falling into the firebox
• Difficulty starting or maintaining a fire
