Planning a project is easier when you can see it. These tools give you a quick, honest starting point in plain English. They’re estimates, not a final design, but they make the conversation with us faster and help you know what to ask.

Have a floor plan or room scan?
Great, send it along. Many newer phones can measure a room and make a simple floor plan with a free scanning app (magicplan and Polycam are two examples; we don’t endorse any one app). A floor plan, a room scan, or even a quick sketch with measurements helps us give you a better estimate.
How to send it: mention it in your request on our contact page and we’ll reply so you can send the file, or text it to (530) 401-7419. You can also email it to walter@ieselectricalservices.com.
Estimates only. Every home is different. A final plan depends on a site visit, what’s inside your walls and ceilings, the equipment you choose, and California electrical code. Estimates from IES are always free.
