Before any lift plan is set, we want an engineer or a structural mover to look the house over. They're the ones qualified to say how it should be supported and what has to be fixed first, and I'd rather you hear that before the house leaves the ground than halfway up.
When the house comes up, all of it comes up evenly, so the finishes inside stay put. One equipment seller describes crews pressurizing hydraulic jacks to lift a short distance, often an inch or two, then setting the load on a fresh layer of cribbing before the next lift. We also tell you up front how long you'll be living around a raised house, so you can plan.
The new foundation is where my priorities show. The subgrade it sits on, dug out and packed, and where the water runs decide whether it stays put, and nobody sees either once it's poured. That's why it's the first thing people want to cut from a budget, and the last thing I'll cut. I'd also rather wait for a better week than pour into bad weather.
Old concrete under a house rarely comes out in one piece. When a failing section has to go, concrete cutting lets us take out just that part in clean pieces. And if the approach to your house is cracked or sinking anyway, it's worth pricing a new concrete driveway at the same visit.
