Re: How to raise deck to make level???
You should be able to physically lift the deck with a fulcrum and lever or a hydraulic bottle or car jack. You would need to be able to get to each support post and disconnect the deck from the post and pier.
I personally would either use a builders level or a string line set to the proper height as a guide to know how high to raise the deck at each support location.
The question is, is the deck attached to the house at an angle or is the low end of the deck is "free". If it's attached to the house, you've got your work cut out for you to detach and reattach the deck in a manner that isn't going to cause water or rot issues with the house. If it's the free end, you've dodged a huge bullet and can just lift the deck into place and resupport it.
I suffer from CDO ... Its like OCD, but in alphabetical order, LIKE IT SHOULD BE!!!
