1920s home. wrap around porch extends 5 ft over / out from home. 25 ft on each side and 40 ft left to right.

old porch supports need to go. 6 inch round wood poles. 6 of them

will 4x4 pt lumber hold it up or do i need those engineered plastic posts?

what if i put in more poles? how many?

Welcome, my name is XXXXX XXXXX I will do my best to help you with your issue

Rick :

You're better off with 6 x 6 treated posts if you stay with the same number. If the porch has been stable all these years then adding more posts isn't critical. You can add more posts but you'll also have to pour concrete piers that extend below the frost line to support each post.

Rick :

You don't need plastic and "plastic" isn't structural. PT will probably last longer than the original posts.

Rick :

I'm assuming you mean the posts that support the deck.
