When it comes to upgrading or installing new doors in your home or commercial space, prehung doors are one of the most practical and popular choices available today. Designed for convenience, accuracy, and long-term performance, prehung doors simplify the installation process while delivering a clean, professional finish.
In this comprehensive guide, we’ll explore what prehung doors are, their benefits, types, materials, installation process, and how to choose the right prehung door for your space.
What Are Prehung Doors?
A prehung door is a door unit that comes already mounted within its frame. It includes the door slab, door frame (jamb), and hinges, all pre-assembled at the factory. Some prehung doors also come with pre-cut holes for door handles and locks, making installation faster and more precise.
Unlike slab doors, which require a separate frame and hinge installation, prehung doors arrive ready to install into a prepared doorway opening.
Why Choose Prehung Doors?
Prehung doors offer several advantages over traditional slab doors, especially for new construction or major renovations.
1. Easier Installation
Since the door is already aligned within the frame, prehung doors reduce the complexity of installation. This makes them ideal for homeowners, contractors, and DIY enthusiasts alike.
2. Perfect Alignment
Factory assembly ensures the door is square and properly aligned within the frame, reducing issues like sticking, uneven gaps, or improper closing.
3. Time-Saving Solution
Prehung doors significantly cut down installation time compared to slab doors, making them a cost-effective option for large projects.
4. Professional Finish
The pre-assembled design provides a clean, seamless appearance that enhances both interior and exterior aesthetics.
