Your fireplace is the heart of your Northern Arizona home during cold months. But water might be quietly entering through your chimney, causing hidden damage behind walls.
By the time you notice ceiling stains near your fireplace, there’s usually already significant damage.
Why Chimneys Leak
Our climate is brutal. Temperature extremes from 90°F to below zero, intense UV at high elevation, monsoon rains, snow, and freeze-thaw cycles stress masonry and flashing.
Damaged chimney crowns are the biggest problem. That concrete seal at the top cracks from freeze-thaw cycles. Water gets in, freezes, expands, makes cracks worse. Eventually water pours in during storms.
Deteriorated flashing (the metal seal where chimney meets roof) corrodes or pulls away. Once it fails, every rainstorm sends water into your structure.
Cracked mortar joints let water penetrate brick. When mortar deteriorates in our harsh climate, water soaks in and travels down inside walls.
Missing or damaged caps leave flues open. Rain and snow fall directly down, damaging liners and fireboxes.
Hidden Damage
Unlike burst pipes with obvious flooding, chimney leaks put moisture in wall cavities and attics where you can’t see it.
Water runs down the flue exterior, soaking the structure and framing. Many Northern Arizona homes have wooden chases around chimneys that rot when repeatedly wet. Joists, rafters, and studs get damaged before you know there’s a leak.
That moisture creates perfect mold conditions. Water-damaged insulation loses effectiveness and has to be removed through opened walls.
Warning Signs
Water stains on ceilings or walls near chimneys
Musty smells near fireplaces
Deteriorating mortar on exterior brickwork
Rust on dampers or fireboxes
Peeling wallpaper or bubbling paint
Visible crown cracks or flashing gaps
White powder (efflorescence) on brick
What to Do
Don’t put it off. Get a professional inspection from a certified chimney sweep.
Check your attic for water stains, wet insulation, or mold.
Document with photos for insurance.
Stop using your fireplace until it’s fixed.
