Not long ago we had an upstairs bathroom pipe leak which caused water to leak down into the kitchen and through the ceiling fan/light fixture. The Plumbing problem is fixed, but the ceiling fan/light is dead. I want to replace the ceiling fan with a standard light fixture, but I'm wondering if this would be a DIY project, or if I should tread carefully and call a professional? Would the whole fixture and everything need replacing or is there another way after water damage. Any help is much appreciated.
