When we had our house inspected before we moved in, the inspector noted that the wire that services electricity to the house "was at the end of its life" and needed to be replaced. Same with the electric panel. Not exactly a fun project, but if we want to be able to turn the lights on, they were both going to need some attention. So while the electricians were here wiring our family room and rehanging our fallen chandelier, we also had them replace the service wire and electrical panel.
In anticipation of a major kitchen remodel in a few years and eventual installation of an air conditioning system, we had them install a 200 amp panel. Chris and I ooohed and ahhhed over all that empty space in the box. In the short term, we'll no longer have to worry about blowing a fuse when running our wallpaper steamer and clothes iron at the same time. That's happened. True story.
As much as I hate to spend a lot of money on something that isn't beautiful, I have to say that it feels so good to be on top of some of these repairs.
Have you endured a similar "no thrills" project recently?
