Everyone
Looking at a deck project, reskinning existing decks over existing 22 year old pressure treated framing. My question, at what point do you consider replacing existing framing, also?
I was going to replace joist hangers, existing ledger bolts, and apply peel and stick to tops of joist, and re-skin.
Existing decks are between 18″ and 9 feet off the ground, and joists are solid. Does the pressure treated material go down hill once it reaches 20 or 25 year guaranty?
Thanks for your thoughts

Sounds identical to a job I did a month or so ago. i'm sure there's some reduction in the chemicals over time at the surface but if they're well treated (big if I'm sure) I'd expect they continue to leech perservative for a long time. In my case, I'd say the vast majority of the framing was fine, but anything that had significant splits etc was replaced.

PaulI reskinned one about three months ago, and the joists looked as good as they did, when I built it 22 years ago.These are part of a condo project, so I have to estimate the balance of useful life, so they can establish a future reserve amount.Thanks

I'd imagine a large part of the servicable life is a function of the preservative, and whether it was applied sufficient to penetrate very deeply. Maybe cutting one if half will give you some insight?
Good luck...PaulB

Might be worth your time to do a test excavation to lok at the post a foot or so bel;ow grade. Otherwise you're just guessing.

FasteddieWe set all the postd on concrete piers 22 years ago, but never used any post anchors though. Deck posts themselves look in real good shape.thanksGreg in Connecticut
Guess it depends on how well the cuts were sealed. I have pulled out PT that was good for 90% but the untreated ends rotted just like spruce.
Do you have access to a non distructive materials inspectors. may cost a few bucks but might bring some peace of mind for all involved.
Are the old fastners going to be eaten buy the new style PT?
ShoemakerNew decking will be a composite,no new pressure treated,only going to replace joists as necessary.None of the ends were sealed at the time the deck was built, but they do look pretty solid.ThanksGreg in Connecticut
