Comprehensive Guide to Garage Door Framing

Creating a sturdy and reliable garage door frame is essential for the longevity and functionality of your garage door. Proper framing ensures that your garage door operates smoothly and securely, providing the necessary support for the door’s weight and movement. In this article, CHS Garage Repair of Seattle, WA, will walk you through the essentials of garage door framing, offering expert tips and advice for both new installations and renovations.


Garage door framing is a critical aspect of any garage door installation. Whether you are building a new garage or replacing an old door, understanding how to frame your garage door properly is crucial. This guide will cover everything from the materials needed to the step-by-step process of framing a garage door, ensuring your project is a success.

Why Proper Garage Door Framing is Important

Proper garage door framing ensures that the door operates efficiently and safely. Incorrect framing can lead to:

  • Misalignment of the door.
  • Increased wear and tear.
  • Safety hazards due to instability.

Materials Needed for Garage Door Framing

Before starting your project, gather the necessary materials:

  • Pressure-treated lumber.
  • Nails and screws.
  • Level.
  • Tape measure.
  • Saw.
  • Hammer.
  • Drill.

Step-by-Step Guide to Garage Door Framing

1. Measure the Opening

The first step in garage door framing is to measure the rough opening. This measurement should match the size of your garage door. Use a tape measure to determine the width and height of the opening.

2. Install the Header

The header is a horizontal beam that spans the top of the garage door opening. It supports the weight of the structure above. Install a header that is strong enough to bear the load, using pressure-treated lumber for durability.

3. Frame the Sides

Next, frame the sides of the opening. These vertical supports, known as king studs, should be placed on either side of the opening. Use a level to ensure they are plumb.

4. Add the Trimmers

Trimmers, or jack studs, are shorter vertical supports that reinforce the sides of the opening. They are installed next to the king studs and help support the header.

5. Install the Sill

The sill is the bottom part of the frame, where the garage door will rest when closed. It should be level and securely attached to the foundation.
