Chimney Repair That Starts With Photos, Not Scare Tactics

Small chimney damage compounds fast. A hairline crack in the crown, a mortar joint losing its seal, flashing lifted by wind—water finds them all, freezes, expands, and turns a $300 fix into a $3,000 one over a single winter. The difference between catching it early and catching it late is the difference between a routine afternoon and major structural work. Early detection saves money and prevents worse problems down the line.

Chimney Pros repairs chimneys the way we inspect them: with photos first, always. A technician documents damage from the roof and inside the flue, walks you through what needs attention now versus what can wait, and gives you one flat price before any work starts. We handle brick and masonry repointing, crown repair and rebuild, flashing, leak sealing, waterproofing, firebox work, dampers, and caps—one crew, start to finish.

Warning signs it can't wait

• Water stains or damp patches on the interior wall beside the chimney or in the attic near the stack
• Mortar joints that are crumbling, missing, or recessed more than a quarter inch below the brick face
• Spalling brick—the face of a brick flaking off in chunks, usually near the roofline
• Efflorescence: white, chalky powder coating the outside of the brick or mortar
• A gap between the flashing and the roof or the brick, visible from the outside
• A musty, wet smell in the room with the fireplace, even when the damper is closed
• Loose or missing pieces of the crown (the concrete cap at the very top of the stack)
• Visible cracks in the crown running in multiple directions, like a spider web pattern

Seeing two or more at once? Stop using the fireplace and call — that combination usually means the system is struggling or unsafe to run.

Common problems we repair

• Mortar joint repointing — freeze-thaw cycles and water exposure wear out mortar, leaving gaps that leak
• Crown seal or resurface — surface cracks and wear in the concrete crown allow water to penetrate downward
• Crown rebuild — deep structural cracks, settlement, or widespread deterioration of the concrete cap
• Flashing reseal or reset — gaps, rust, or lifting at the junction where the chimney meets the roof
• Spalling brick replacement — the brick face breaks apart and sheds due to freeze-thaw and moisture cycles
• Firebox repair — internal brick and mortar erode from heat cycling and burning wood, reducing draft and safety
• Smoke chamber repair — cracks and deterioration in the chamber above the firebox reduce efficiency and allow smoke leaks
• Damper repair or replacement — a stuck, rusted, or cracked damper fails to seal, letting heat escape or rain in
• Cap installation or replacement — a missing or damaged cap allows water and animals into the flue

What chimney repair costs

Most common repairs range from $250 to $1,400. Costs depend on the scope and location of damage; the estimate is always free and approved in writing before work begins.
