I had some issues with a few light fixtures in my apartment that didn't work. On both occasions, Christopher Jon Electrical came first to check out the problem and give me an estimate. They then came back on second day to do the repairs. They put down a tarp and cut a bit of the ceiling to get to the wiring. They resolved the problem, patched up the ceiling and left not mess. Apparently, some of the wiring presented a fire hazard so I'm glad they fixed it.
