A simple two bath 1600 sq ft home on raised foundation would probably cost about $4500. You could shop that around as there are a lot of folks who do that. The job takes approximately 1 1/2 days. If you are on a slab then you typically have the folks go through the walls which requires a lot of drywall repairs. The job can take approximately 3 days +. There are companies in Orange County that specialize in this activity. Just make sure they use the proper grade copper. Typically they will bring the new copper up to the fixure (sink) and then hook it up. This would be an excellent time to consider a recirculating pump in the system as well as verify your water heater is good. A recirculating pump insures that when you turn the hot water on from any faucet that hot water runs very quickly. They are great especially in larger homes. Also make sure they insulate the copper throughout to save on gas or electric.
