Why fitting vertical blinds correctly matters
Vertical blinds are one of the most practical and versatile ways to dress a window. Their louvres (slats) rotate to control light and can be drawn neatly to the side when you want an open view. But to get the best from them, they need to be fitted properly. A well-installed blind will glide smoothly, hang evenly, and give you precise light control, while a poorly fitted one can catch, tilt awkwardly, or leave gaps.
Tools and preparation
Before you get started, gather a few essentials: a drill with suitable bits, screws and wall plugs, a pencil, measuring tape, and a spirit level. It’s also worth having someone nearby to hold the blind in place while you secure it. Double-check your measurements from ordering to be sure you’re working with the right size blind.
Inside recess vs outside mount
Vertical blinds can be fitted inside the recess of your window (a neat, built-in look) or outside the recess (covering the frame completely, ideal if you want to block more light). Inside fittings require accurate measurement, as even a few millimetres can make a difference to how the slats hang. Outside fittings are generally more forgiving and can make windows appear larger.
Step-by-step fitting guide
1. Mark your positions
Hold the headrail up to the window in the desired position. Use a pencil to mark where the brackets will go – usually at each end, and additional ones in the middle for longer blinds. Make sure everything lines up with a spirit level to avoid slats hanging unevenly.
2. Fix the brackets
Drill the holes where you marked, insert wall plugs if needed, then screw the brackets firmly into place. For recess fitting, brackets are usually attached to the top of the recess; for exact fitting, they go on the wall or ceiling just above the window.
3. Clip in the headrail
Once the brackets are secure, clip the headrail into place. It should click firmly but still be easy to remove later if you need to.
4. Attach the louvres
Hook each vertical slat into the headrail carriers one by one. Start at one end and work your way across, checking as you go that they hang evenly.
5. Add weights and chain
At the base of each louvre, slot in the weights, then connect them together with the stabilising chain. This keeps them aligned and stops them swinging about when the window’s open.
6. Test the mechanism
Pull the chain or twist the wand to rotate the slats. Then draw them fully open and closed a few times to check everything glides smoothly. Make any small adjustments before finishing up.
Common fitting hiccups and fixes
If the blind looks uneven, double-check the brackets are level. Slats that won’t rotate usually mean one hasn’t clicked in properly at the top – unhook and reattach it. If the chain feels stiff, check that it isn’t tangled at the bottom. Taking a few extra minutes to sort these issues now will save frustration later.
When to get professional help
While many people are comfortable fitting blinds themselves, sometimes it’s worth leaving it to the experts. If you’re dealing with very wide windows, bay windows, or unusual recesses, a professional fitter can ensure the blind is installed perfectly. Specialists like Kelly’s Blinds take the hassle out of measuring and fitting, leaving you with blinds that work flawlessly from day one.
