Installing Roller Blinds: An Outside Mount Guide
Embarking on a DIY roller blind installation project? An outside mount is an excellent choice for a clean, streamlined look. This guide will walk you through the process, ensuring your blinds are installed perfectly for optimal functionality and aesthetic appeal.
Understanding Outside Mount Roller Blinds
Outside mount roller blinds are installed on the exterior of your window frame, making them ideal for windows with limited depth or where you want to maximize light entry. They also provide a sleek, modern look, as the blind hardware is not visible from the inside.
Tools You'll Need
- Tape measure
- Pencil
- Drill with appropriate bit (usually 1/8" or 3/32")
- Screwdriver (depending on the type of screws provided)
- Level
- Ladder (for high windows)
Step-by-Step Installation Guide
Measurements
Accurate measurements are crucial for a perfect fit. Here's how to measure for outside mount roller blinds:

- Measure the width of your window frame where you want the blind to be installed.
- Measure the height from the top of the window frame to where you want the blind to end. Add 3" to 4" to this measurement to account for the blind's headrail and to ensure proper light blocking.
Installing the Mounting Brackets
Once you have your measurements, it's time to install the mounting brackets. Here's how:
- Mark the bracket placement on your wall or window frame using your measurements and a level to ensure they're straight.
- Drill pilot holes at the marked spots.
- Secure the brackets to the wall or frame using the appropriate screws, ensuring they're level and tight.
Installing the Roller Blind Headrail
With the brackets installed, you can now attach the roller blind headrail:
- Place the headrail onto the brackets, ensuring it's level.
- Secure the headrail to the brackets using the provided screws.
Installing the Blind Fabric
Now that the headrail is secure, it's time to install the blind fabric:

- Unroll the blind fabric and insert the bottom into the provided valance or hem.
- Roll the fabric back onto the tube, ensuring it's even and taut.
- Slide the fabric onto the headrail, engaging the clutch mechanism.
Testing Your New Roller Blinds
Before you step back to admire your handiwork, test your new roller blinds to ensure they're working correctly:
- Lower the blind by pulling the cord or using the wand.
- Raise the blind to ensure it rolls back up smoothly and locks into place.
- Check that the blind covers the window evenly and blocks light as expected.
Tips for a Perfect Installation
Here are a few tips to ensure your outside mount roller blind installation is perfect:
- Always measure twice to avoid errors.
- Use a level for all measurements and installations to ensure your blinds hang straight.
- If you're unsure about any part of the installation, don't hesitate to consult the manufacturer's instructions or contact a professional.
