How do you jack a house up an inch or two to repair the foundation?

Ideally, a house foundation repair would require only jacking the area in need of repair as little as possible, perhaps bringing to a point level with or slightly above the line of foundation to each side of it. Jacking a house can be dangerous and involves the use of temporary beams and hydraulic jacks. Overjacking can cause harm to interior finishes and exterior veneer brick. Use caution, and lift in small amounts with daylong intervals between. Or hire a professional.
