Decks, Patios, Porches and Docks - re-leveling an existing deck

I have a floating deck that is approximately 8' by 10' that has risen up approximatley 2 inches in the front. The deck is 2 feet off the ground and is supported by 4" posts at the corners. What is the best way to re-level the deck?

Where are you at??

The only reason that I can think of as to why the deck has "risen" is frost heave. If that's the case, your footings aren't deep enough.

:thumbup: Thanks for the response Lefty,

Located in Northern Michigan. Was thinking about jacking up the deck, re-notching the existing posts and continue using them. Not sure if that is the way to go. Should I just sink new posts and cut out the old?

Renotching the existing posts would simply be a temporary fix. The existing footings are not deep enough, and they will heave again.

I would start with new footings that are at least 42" deep -- below your frost line. Make them 18" square, fill a foot of the hole with concrete, put a 10" or 12" sonotube on top of that which extends 8" above grade. Fill the sonotube with concrete and the hole around it with dirt, working your way up about a foot at a time. Once the sonotube is full, set a PB44 or CB44 in the top of it, directly under your beam. Once the concrete has cured for a few days, install new posts.

Will Do....thanks for the help.
