redecking question

| Hi all,
I have a 25 year old deck in Austin, TX. The cedar decking needs to be replaced. The joist span is 24 inches. The current decking profile is 2X6. I need to keep the current deck height to match the pool height.
1. How many useful years can I expect from a PT wood frame with good air circulation? I am planning to stay in the house for another 15 - 20 years. The frame will be 40+ years old when I move. Not sure if I should put a new IPE decking on an old frame...
2. If I go with 5/4 X 6 IPE, I need to add about half inch wood under IPE so that the same deck height can be preserved. What do you think about using the half inch wood?
3. How difficult is it to double the joists from 24" to 12" OC? 1 X 6 IPE has 16" OC limit
Thanks,
Scott

| If it were me I would replace the frame. The cost of those materials is not that much compared with the cost of the decking and railing. Then you can fix the span problem, you have a chance to change up the shape/feel and layout if needed and you don't have to worry about it structurally. Especially since you are planning to be there for another 15 years. Riles |

| I think you mean the layout is on 24" centers, not the joist span. It makes no sense to put 5/4 ipe on a 25 year old frame. Furring the joist with 1/2" strips of any flavor of wood is a mistake. At 25 years old that cedar deck is at the end of it's life, time for new deck imo. |

| Yes, the layout of the joists is 24" centers. Time for a new deck means the whole structure or just the decking? |

| Yes, time for a whole new deck, imo. What sense does it make to put high $ decking like 5/4 ipe on a frame that is 25 years old? |

| I'm with the others. Re-frame. If it's that old it's probably got some other code issues (4x4 posts instead of 6x6, end nailed instead of joist hangers, post anchors vs. embedded in concrete, etc.) and it would be good to bring it up to current code and make it more solid at the same time. You need 16" centers for your IPE anyway. Post some photos and we can give you a read on any other issues you'll want to fix while you're at it. :-) |
