Double roller blinds are a clever way to combine privacy and light control: a blockout layer for sleep or privacy and a sunscreen layer for daytime glare control. If you’re handy around the house you might be tempted to install them yourself, and with the right guidance it’s absolutely doable. This guide, written by the team at Brighter Blinds & Doors, walks you through how to install double roller blinds properly, safely, and neatly. Wherever you’re in Melbourne or Victoria, this will give you the confidence to measure, mount, and finish like a pro or call Brighter Blinds & Doors to do it for you.

Tools & Prep: What You’ll Need

Before you start, gather these basics so the job flows smoothly. You’ll need a drill, tape measure, pencil, spirit level, screwdriver, appropriate screws/anchors for your wall type, and the supplied brackets and fittings. This kit covers most of what appears in any double roller blinds installation guide or double roller blinds DIY installation.

Pro tip: Lay out all parts from the box and check your instructions. If anything’s missing, don’t proceed contact the supplier or Brighter Blinds & Doors for help.

Step 1 — Measure Your Window Carefully

Good installation starts with correct measurements. For blinds on double windows or wide openings, measure the width in three places (top, middle, bottom) and use the smallest figure. Measure height from where the top of the bracket will sit down to where you want the blind to finish. When you’re following how to assemble a roller blind later, these measurements keep your blinds neat and square.

If you’re unsure about measuring, Brighter Blinds & Doors offers accurate measure-and-quote services so you don’t guess.

Step 2 — Decide Inside (Recess) or Outside (Face) Fit

Choosing the right mount matters. If you want a trim internal look, go recess fit double roller blinds (inside the window frame). For maximum blackout and easier installation over obstructions, choose face fit double roller blinds (outside mount).

How to hang roller blinds inside mount: Check that your window recess depth accommodates the brackets and rollers without rubbing.
How to hang roller blinds outside mount: Mark where the blind should sit on the wall or architrave so it overlaps the window enough to block light.

Step 3 — Mark & Mount the Brackets

Now you’re ready for mounting roller blinds. Using your measurements and a spirit level, mark the bracket positions. For double rollers you’ll typically have one double bracket assembly or two brackets positioned to accept both rollers. Pre-drill pilot holes, use suitable anchors for masonry or plaster, and secure the brackets firmly.

This is the foundational step that determines whether the blinds hang straight — take your time.

Step 4 — How Do You Put Up Roller Blinds (Attach the Rollers)?

With brackets in place, it’s time to install double roller blinds. Start with the blind that will be closest to the wall (often the blockout), then fit the sunscreen in front or behind depending on your bracket type. The typical sequence is:

Insert the idle end into the bracket.
Compress spring pins or slide the roller into the control side.
Ensure the chain or control mechanism sits in the correct orientation.

If you’re wondering how you put up roller blinds on a double bracket, the trick is aligning both rollers so their ends sit squarely in the brackets otherwise you’ll get uneven rolling.

Step 5 — Adjust, Test & Fine-Tune

Once the rollers are in, operate both blinds to check they roll smoothly. If a blind tips or rolls unevenly, check end caps, bracket seating, and that the roller is straight. This is also when you’ll make small tension adjustments to avoid sagging or slack.

If you need instructions on how to fit double roller blinds to achieve perfect alignment, test each roller separately and make micro-adjustments until both travel smoothly.

Step 6 — Safety, Chains & Final Fixings

Safety is non-negotiable. Install the child-safety device and chain tensioner per Australian guidelines; this reduces cord hazards and keeps your installation compliant. This step answers the question how do you install roller shades safely whether they’re single or double rollers.

Next, tidy any visible screws, clean the window area, and verify both blinds sit flush and finish at the right height.

Troubleshooting: Common Problems & Simple Fixes

Blind rolls unevenly: Check bracket seating and that the roller is fully seated on both ends.
Chain feels tight or slips: Check the control sprocket and correct its seating.
Brackets pull away from the wall: Use stronger anchors or add extra fixings for wide blinds on double windows.
If a fix feels beyond your tools or comfort level, Brighter Blinds & Doors will happily complete the job for you.
