Door Installation 101: How to Install a RapidHang™ Pre-Hung Door from Door to Door Co.

Replacing interior doors is one of the easiest ways to refresh the look and feel of your home. If you’ve just placed an order—or are thinking about it—you may be wondering what to expect once your door arrives. How much assembly is required? And is this something you can install yourself?

This guide will walk you through the Door to Door Co. pre-hung door installation process, including what comes in the box, the tools you’ll need, and how to prepare for a smooth, successful install.

What to Expect When Your Interior Door Arrives

When you order a RapidHang™ pre-hung door from Door to Door Co., your shipment will include the door slab, hinges, and the door frame (also called a jamb kit). The key thing to know: while everything is sized and prepped for installation, the frame will arrive disassembled.

Why? Shipping the jamb pieces flat-packed helps prevent damage in transit and makes your order easier to handle on delivery day. The frame is clearly labeled and quick to assemble on-site, even if it’s your first time tackling a door installation.

Tools You'll Need for DIY Door Installation

Installing a pre-hung door with our RapidHang™ Prehanging Kit is a project many homeowners can complete themselves with just a few tools. Here’s what you’ll need on hand:

• Measuring Tape
• Level
• Drill or screwdriver
• Shims
• Hammer
• Nail set or finish nailer

Expect to spend about 10–15 minutes assembling the jamb kit, and 1–2 hours total to complete the installation. Taking your time with leveling and shimming will ensure your door opens and closes properly for years to come.

Common Questions About Pre-Hung Door Installation

Do I need a contractor to install a pre-hung door?
Not necessarily. If you're comfortable using basic tools and following clear instructions, this can be a rewarding DIY project. Of course, you can always hire a handyman or contractor if you'd prefer professional help.

Why doesn’t the frame come assembled?
Pre-assembling the jamb adds bulk to the shipment and increases the risk of damage. Door to Door Co.’s RapidHang™ Prehanging Kit arrives safely and ready for quick assembly in your space.

What if my door opening isn’t perfectly square?
This is a common issue—especially in older homes. That’s why we recommend using shims to adjust and level your new door. Our RapidHang™ Prehanging Kits are designed to be flexible enough to work with slightly uneven openings.
