This is a pretty common question, and we say we like to leave it as good, if not better than when we got there. Of course, with contractor-type work, there will potentially be some cutting of holes, wiring, and parts used on the job. When we are job, we review the area we worked in ensure we have put back anything which was moved for us to complete our work. We also tidy up the areas where we were working to minimize anything you need to do after we finish. “A job isn’t complete until the clean-up is done” isn’t just a saying, but something we go by every single day.
This, of course, is not going to be the case will every electrician in the Portland area. Check their reviews online and ask the company directly if clean-up is involved in their job so you can know what to expect in the aftermath.
