Chimney inspections in Winter Springs.

1. 1 of 6. The cap, at the roofline.

   Sunshine, summer cloudbursts and wind reach the cap before any other part. Under its lid the rain is shed, and the mesh keeps sparks in and animals out.

   Check for: storm dents, loose mesh, rusty fasteners on the lid.

2. 2 of 6. The crown, below the lid.

   During a downpour a hairline crack in a crown absorbs water and stays damp for long after. Florida's building code wants the cap pitched so water runs off, with a drip edge and a caulked gap beside the flue liner (R1003.9.1).

   Check for: hairline cracks, chipped corners, a slab lifting off the flue, no drip edge.

3. 3 of 6. The flashing, where roof and stack meet.

   The metal collar called flashing closes the seam between chimney and roof, and wind-driven rain tests every edge that has lifted. A chimney wider than 30 inches along the ridge, and not meeting the ridgeline, also needs a cricket behind it (R1003.20).

   Check for: curled edges, cracked sealant, rust streaks, a damp ceiling beneath, no cricket on a broad chimney.

4. 4 of 6. The flue liner, inside the masonry.

   Smoke and fumes exit the house through the liner, which the Florida code requires in a masonry chimney (R1003.11). With 1989 as the median year built in Winter Springs, a typical flue has operated for upward of thirty-five years, long enough that a tile can shift or a seam corrode.

   Check for: open seams, cracked or misplaced tiles, a liner mismatched to its appliance.

5. 5 of 6. The smoke chamber and damper, just over the firebox.

   Deposits collect first on the shelf over the damper. With only a few fires a year it fills gradually, but it is never entirely empty.

   Check for: glossy or tarry deposits, a damper that will not shut, a shelf that flakes or tilts.

   

6. 6 of 6. The firebox, on the hearth.

   Year after year heat works on the firebox walls, cracking firebrick and loosening joints. A narrow gap is a minor repair; once heat has reached the framing, the repair grows.

   Check for: gaps between bricks, firebrick that flakes or splits, a hearth that moves underfoot.

   

1. Ahead of the cool season.

   NFPA recommends an inspection once a year. Fireplaces here are used in short spells, so the weeks before the first cool front are a handy time to book. A hard cold snap still arrives occasionally: at the county's airport weather station, temperatures reached 32 degrees or lower on eight days from January 2 to 13, 2010, bottoming out at 25 degrees.

   

2. Buying, selling or inheriting.

   Under NFPA 211 a change of owner calls for Level 2, camera pass through the flue included. Winter Springs houses cluster in one era: Census Bureau estimates for 2020 to 2024 give a median build year of 1989 and place 11,205 of 16,020 homes in the 1970 to 1999 decades, with 2,113 built since 2010. No buyer should treat one chimney as a guide to the next.

3. After a chimney fire.

   Once a chimney has had a fire, NFPA 211 considers the whole system possibly damaged and moves the inspection up to Level 2.

   

4. Following a hurricane, lightning or severe weather.

   Wind, rain and lightning strike the roof-level parts first: cap, crown and flashing. Winter Springs High School's weather station logged a 51-knot gust in Hurricane Milton, and lightning started a fire in June 2007 that destroyed a home in the city.

5. Adding a stove, insert or gas logs.

   Installing a stove, insert or gas logs changes how the whole system works, and NFPA 211 counts a change of appliance as a reason for Level 2. If the flue has carried wood smoke before, Florida's code wants it cleaned before a gas appliance is connected (Fuel Gas 501.15.2).
