The average cost to install shutters will vary depending on the type of shutters you choose, the size and complexity of your window, and the level of expertise of the installer. Generally speaking, plantation shutters will be more expensive than traditional wood shutters, and custom-made shutters will be more expensive than off-the-shelf models. Installation costs can range from a few hundred dollars to a few thousand dollars, so it's important to get estimates from several different retailers or installers before making a purchase. Be sure to ask about any hidden costs, such as installation fees or shipping charges, and read reviews from previous customers to make sure you're hiring a reputable company.
