Why careful installation matters
Double roller blinds feature two blinds in one system – usually a light-filtering fabric for daytime use and a blackout or heavier fabric for privacy or night. Installing them correctly ensures both blinds operate smoothly, align properly, and provide the intended light control. Poor installation can lead to uneven rolling, snagging, or difficulty operating either fabric.
Tools you’ll need
A drill with appropriate bits, screws and plugs, tape measure, pencil, spirit level, and a screwdriver are needed. A step ladder will help with taller windows, and a second person can assist with holding the blind in place during installation.
Inside or outside mounting
Double roller blinds can be fitted inside the window recess for a neat look, or outside the recess to cover more of the window and block extra light. Inside fitting requires precise measurement so both fabrics roll evenly, while outside fitting is slightly more forgiving and can improve light-blocking performance.
Step-by-step installation guide
- Mark the bracket positions: Hold the double roller blind in place and mark where the brackets will be fixed. Ensure all marks are level using a spirit level.
- Fix the brackets: Drill pilot holes, insert plugs if needed, and secure the brackets with screws. For wider blinds, add extra brackets to support both rollers.
- Insert the double roller system: Slot the two blinds into the brackets, starting with the pin end and securing the control side.
- Install the chains or controls: Each blind has its own chain or control mechanism. Make sure they hang freely and do not tangle. For motorised models, check remotes or switches are paired correctly.
- Test the blinds: Lower and raise each blind independently, then together, to confirm smooth operation and alignment.
Common installation issues
If the blinds roll unevenly, check that the brackets are level and the headrail is centred. Chains that tangle usually need adjustment to hang freely. For inside fits, make sure there is enough recess depth to accommodate both blinds without rubbing against the frame.
When to call in the experts
Double roller blinds can be heavier and more complex than single blinds, making professional installation a smart choice for wide windows or tricky placements. Specialists like Double Roller blinds with fitting service can measure, supply, and install your blinds to ensure perfect alignment and smooth operation.

FAQ – How to Install Double Roller Blinds?
Do double roller blinds need extra space?
Yes – they require sufficient recess depth or an outside fit to allow both fabrics to roll smoothly.
Why do the blinds roll unevenly?
It’s usually due to brackets not being level or the headrail being off-centre. Adjust the brackets to fix this.
Can both blinds be operated with one chain?
No – each blind has its own control mechanism, whether chain, wand, or motorised system.
