I've recently dug out the basement of my one story house, effectively converting it to a two story house. This was done due to the way the lot was laid out. It looks much nicer and I have a half-way decent yard now. There are a few pics at

Anyway, I'd like to convert the block basement into a new first floor. My idea was to jack the house up a couple feet, knock the blocks out, and then build wood walls. The blocks are not in that great of shape and the foundation wall is bowed in several places.

Q1 - Are there resources available for a do-it-yourselfer to jack up a house?

Q2 - If I were to get crazy(er) and want a new basement, under the new first floor, is it possible to jack the the house, build the basement and first floor, then set the second floor back down?

This is not a big house - 24x48 outside dimension, and I have almost no furniture in it.

Any help is greatly appreciated...Thx.

First things first. It's unwise to try to jack up a whole house by oneself if not a pro. I'm not into advertising for the pros, but there comes a time....

In oder to insure that the house lifts and settles back as one intact unit, with as few wall and window cracks as possible, with as few plumbing systems cracked or bent as possible, and generally with as few, or no, cracks and stress fractures at all, you'll need someone who has the equipment and no-how (and jacks) to lift the house at once. You'll need a couple of beams (usually steel) under the house from end to end supporting other smaller beams running side to side, all lifted together by hydraulic jacks to a point where cribbing can be installed to hold the house up while you work under it. Never depend on the jacks to hold it long term while you're under it.

In other words, get a professional.

2 lifetime posts preference was going to be dynamite, but I can see where hydraulic jacks done by a professional would be a little safer :-)

Given the fact that this project is out of a do-it-yourselfer's expertise, do you know how much I could expect to pay a professional for this type of service?
