A door insert is an ideal way to bring light into an entryway or brighten a dark hallway and at the same time improve an ordinary door. The insert gives an existing door a new lease on life while opening up the interior with daylight. These door inserts come in kits for both interior and exterior doors, some with internal blinds, in a variety of sizes. For example a kit for an interior door fits a standard slab or panel door that is 1 3/8 inches thick, while the exterior kit fits a typical 1 3/4-inch thick slab or panel on an exterior door.
The insert kits are designed for easy installation with a handy homeowner in mind, or you can hire a carpenter to do the job. To install a 22-inch-by-58-inch exterior door kit, a carpenter will charge $580, which includes labor and material. If you have carpentry experience and tools, you can buy the kit for $380 and do the installation yourself, saving 34 percent.
