When replacing a chandelier, there is little need to do any significant re-modifications. The cost will vary depending on whether the existing wiring is functional. Expect to pay around $115 to $280. If you install a chandelier in a position without any wiring, installation costs range from $145 to $400. Certain factors can also increase the price, such as upgrading junction boxes or installing heavy fixtures. Updater: Alannah Koene
