If you're doing any major remodeling, one of the easiest and cheapest improvements is to use twisted power cables, or twist normal Romex cables: http://www.eiwellspring.org/emc/WiringHousePart1.htm

Remodeling is also a good opportunity to fix any wiring errors*.

And if you have walls open or siding removed, you might consider adding dedicated high frequency ground connections for your shielding. Engineering textbooks will tell you that the ideal ground connection is a wide sheet of aluminum or copper going as directly as possible into the earth. So for example you could run a sheet of copper flashing or heavy-duty aluminum foil under the siding (if your building has it), from the base of a window right into the ground underneath it.

(*I had a vivid demonstration of the significance of this recently while visiting a remote off-grid house built by an engineer with ES; 'dirty power' on a properly installed circuit was only measurable within a few feet of the wire when we looked for it with a laboratory-grade magnetic field meter, but bad grounding would cause a measurable field throughout the entire house.)
