We recently had a new porch built. Our contractor did not provide any spacing between the deck boards and in just a few months, the boards are cupping, warping, and splitting. He claims this is how we wanted it installed. The only thing we ever said to him was that it 'looked good' w/ no spacing. He agreed. We asked if there were any issues w/ this and he said that we'd have to sweep out between the boards as dust, dirt would collect there and that was it. He is refusing to warranty any of the wood saying that the boards just failed and it was bad wood. Is this something that would just be considered poor workmanship or would it be a situation where a Construction Contractor Board would rule in our favor? Any thoughts would be greatly appreciated. Everywhere I've read online it says you HAVE to put spacing of at least 3/16" between boards. Please help???
