Leveling a 9x12 wood shed

[rmanrman]

I have a prebuilt 9x12 wood shed that has two 4x4 pt sleepers attached under the floor joists. That base is 6inch Qp aka crusher run compacted stone
Well I converted this shed into an outdoor kitchen with frig cabinets granite countertops and all the stuff necessary for outdoor dining. The problem is the shed after two years has a 1&1/2 inch sag to the long side which is where the double entry door is. Now the tough part I have pavers from the house to the shed and the siding vinyl is almost resting on the pavers. How can this shed be lifted so as to slide a 2x4x12 foot flat under the 4x4 spellers? Do I need to remove pavers (least option they are 4 different sizes). No way to get a crane to the location and I assuming very expensive. Could two hydraulic floor jacks lift this shed? Have no idea how heavy it is. Guess 2000 lbs. Need to stop the sinking down or soon the steel doors will not open. Thanks

I've jacked my 8 x 12 shed up with a floor jack I placed it under the skid.

Dig a hole under it to access the sleeper and jack it up.

GJ member Couch67 just jacked his up to replace the floor.

There are some other threads here also

not sure what your exterior is but have a look at my signature of the old shed. I fastened 2x10s to the exterior and used those as jack points. I used the tire jack from my accord to lift up each corner a few inches at a time.

I leveled a couple of old 10x16 sheds. Use a hydraulic jack under the 4x4 and then shim as needed with pavers, cinderblock, etc. I used a couple cedar shingles for fine adjustment.

Yup. Dig for access and get to jacking.
I recommend the cheap bottle jack from Walmart. Like 17 bucks.

If your access is limited, this will work...

I've used my to move some things that I thought it wouldn't handle...but it did.

I used old fashioned screw jacks to lift half a 40x40 x 3 story frame house 18 inches.
(While we were living in it)
Your bigger problem is going to be jack placement and any shim tapering.

This is how I dealt with mine....jacked it up and poured a floor. Read/look here:

Amazing how much you can lift with a very basic jack, the mangiest looking car jack will get it up a couple of inches, a bit of timber blocking will hold it there while you move another corner... and so on. Actually finding and having enough timber packing will turn out to be the hardest part of the job! (Cut up a pallet or two)

If you don't want to lift it from the outside, you can always remove flooring and lift it from the inside.
