How long can you store firewood before it rots or gets otherwise turned into sawdust? And what's the best way to extend that time? I've mentioned before that I often see opportunities for free firewood. There's a LOT of construction going on in our area (unfortunately, but I guess it's inescapable in many places) which means lots of trees cut down, and they're not used. In fact, tree maintenance guys get PAID to TAKE the wood, which I'm guessing they will then sell for yet more profit. So obviously, people want to save money by leaving the logs there and offering them free. You just have to age it 6-12 months if you're burning it indoors. Lots of opportunities to stock up. We already have a bunch, probably more than we'll use in 3 winters. But I hate to pass up opportunities. About half of the wood stacked in our backyard is already rotting - the previous owner left it, and I don't know how long it's been there. Obviously we need to sort, split, stack and build a shelter for it. But I need to know how long wood can be stored, otherwise if we got any more we'd just be wasting effort. OTOH... If I invested in a cheap pickup truck and a log splitter, could I turn a profit by hauling cords of wood to sell in snooty neighborhoods on a crisp autumn day?
