Three gas leaks in a ten-year-old home

The owner bought this home new and, ten years on, called us for a first maintenance check. Opening the attic hatch, we smelled gas. Leak-detection solution on every joint found three leaks. With the fittings apart, there was no sealant on them at all, left that way since installation. If you're worried about your own furnace, the gas company will check for leaks free of charge.
