Generally speaking, electricians want to stay in the realm of what is within the wall and installing new fixtures, but stay away from repair. If there is a problem with a light fixture, they will replace it. If a fixture is dirty, it is up to you to clean it.
This is where we come in.
From cleaning to repair, if a light fixture is in good condition, we can try to fix it.
If it is not in good condition, depending on what the issue is, we can possibly restore it.
