Prehung Exterior Doors

A prehung door comes already mounted to a frame, making it a ready-to-install unit. It includes the door slab, hinges, and the full frame — so instead of hanging the door yourself, you install the entire frame and door as one piece.

Prehung doors are great for quicker and easier installation, especially when replacing an old door and frame. They come aligned and weather-tight from the start, which can help improve insulation, security, and long-term performance.

They can be heavier and bulkier to handle since the frame is attached, which may make solo installation trickier. If your existing frame is in perfect condition, you may not need a full prehung unit — in that case, a slab-only door could be a more cost-effective option.

Most prehung exterior doors come with the door slab, frame, hinges, and weatherstripping. You’ll typically need to add your own handle, lockset, and sometimes trim or casing.

If you’re dealing with a damaged frame, new construction, or you just want to make sure the door is square and aligned properly, a prehung door is your best bet. Slab doors work better if you’re keeping your existing frame and just replacing the door itself.

You’ll want to measure the rough opening in your wall — that’s the framed space the entire unit fits into. If you need help choosing the right prehung door unit for your home or project, we're here to help.
