Outside the House
Walk around the home and look up at the chimney. Check for: visible cracks in the brick, missing or crumbling mortar joints, spalling brick faces, white staining (efflorescence), a chimney that looks like it's leaning, debris on the roof beneath the chimney, and the condition of the chimney cap (or whether one is missing entirely).
At the Roofline
If you can safely view the flashing — where the chimney meets the roof — look for: lifted or curled metal, rust, exposed nails, gaps, and any spots where someone has slathered roof tar instead of doing a proper repair. All of these indicate the flashing is past its useful life.
Inside the Firebox
Open the damper and look up. Check for: visible cracks in the flue tile, pieces of mortar or tile in the firebox, rust on the damper, water stains on the inside of the firebox walls, and creosote buildup. For wood-burning fireplaces, more than 1/8" of creosote is a fire hazard and the chimney should be cleaned.
Around the Chimney Inside the House
In rooms adjacent to the chimney chase, look for water stains on the ceiling, peeling paint, soft spots in the drywall, or musty smells. In the attic, check the framing around the chimney for staining or rot.
Before Listing Your Home
Massachusetts buyers' inspectors will catch chimney issues — and they'll show up in the inspection report. Most chimney problems are cheaper to fix before listing than to negotiate against at the closing table. A pre-listing chimney inspection often pays for itself many times over.
When to Call a Pro
If you see any of these signs — or you can't safely access the roof to check yourself — a professional Level 1 or Level 2 inspection is the right call. Most local chimney pros, including us, will do a free visual inspection as part of an estimate.
