Because of water damage to the wall of my house I had to remove my existing deck. I was able to leave the outer frame but had to remove ledger board, joists and deck boards.
I have repaired water damage and I am ready to rebuild deck. The old deck had no joist hangers and honestly was not built very well. I am going to make it free standing with posts in concrete and 2x10 beams. More questions about that later.
I am trying to determine how much and what sizes of lumber I need. My big question is deck boards. The deck is just over 18 feet wide, and the longest 5/4x6 deck boards I can get are 16 feet. How do I figure out what lengths I should use? Obviously I would like the fewest number of seams and to not waste money buying the wrong lengths. I can't put them on at an angle without removing all the railings and it also sits partially against a wall. I have tried some of the online deck designers but they have me using 18 footers. Is there a software to give me the best layout for the deck boards?
