i have no water in my house..what are some things i could look for before i call a well and pump company?

Make sure the breaker for the well hasn't popped. Check and make sure any GFI's haven't been tripped. (builders electrician have been known to tie stuff together that they shouldn't)

Check the pressure switch to see if there's a buildup of crud on the contacts. Shut power to the system, open the contacts apart and put a nail file between the contacts. A couple of strokes should clean things up. Do this to all four contacts. If you're only wired to two contacts, then maybe switch the wiring to the unused pair.

If it's not the switch then it might be the pump or the starter or the relay (I'm assuming a submersible well pump), which will mean a service call by a qualified technician.

Another possibility is that the well is running low on water, and the pump has drawn in air and become airlocked, which will cause it to quit pumping. If it is a submersible pump (down inside the well), turning off the electric power (breaker) to the pump for 15 minutes, then back on, will temporarily solve the problem. If your pump is above ground, it may need to be "primed" before it will work again.
