The Chimney Safety Institute of America has some smart advice for heading off potentially dangerous post-flood damage:

• Replace gas fireplace logs. Water and small bits of debris can clog valves, and metal parts may rapidly deteriorate after exposure to water, causing gas leaks.

• Replace fireplace fans and wiring. Electrical connections and water just don’t mix. Don’t take the chance; before you flip the switch, get new parts.

• Have appliances and heaters professionally inspected. Get a furnace pro or heating-and-cooling specialist to check your heating system and water heater for damage to fans, wiring, gas connections, and burner units.

• Check the chimney. Call in a certified chimney sweep to do a thorough chimney inspection of your fireplace box and chimney for damage to masonry, mortar, and flue components.
