Blind Installation Mistakes (and How to Avoid Them)

Installing blinds might look simple, but there’s a reason it sometimes doesn’t go as planned. From uneven brackets to blinds that don’t quite cover the window, we’ve seen a fair share of installations that didn’t turn out quite as expected.

At Total Look Blinds, we’re all about making your blinds work beautifully, not just look good in the box. Whether you're trying to improve privacy, light control, or aesthetics, it's worth getting the details right. Below are the most common blind installation mistakes we come across in homes across Auckland and beyond, along with practical ways to avoid them.

Inaccurate Measurement

If you’re installing window blinds, measurement is everything. A few millimetres too short or too wide, and you’re left with gaps, overhangs, or blinds that simply don’t fit at all. Unfortunately, measuring mistakes are more common than you’d think, especially when it’s rushed or done without a clear plan.

In our experience with NZ blinds, mismeasurements usually happen when:

• The window’s only measured in one spot
• The tape measure isn’t straight (or is flexible and inaccurate)
• The difference between recess and face fitting isn’t taken into account

Here’s how to measure properly:

• Always use a rigid metal tape measure
• Measure both width and drop in three places (top, middle, bottom) and go with the smallest figure
• Decide early on whether your blinds will sit inside the frame (recess fit) or outside (face fit) — the approach makes a big difference
• Don’t round your numbers, precision here saves problems later

And if you’d rather skip the measuring altogether, we offer professional in-home installation to ensure your blinds fit exactly as they should, the first time.

Overlooking the Wall You’re Mounting Into

One of the lesser-known stumbling blocks of blind installation? The surface you’re fixing them to. Using the wrong tools or fittings can lead to blinds that fall out of alignment or fall out altogether.

Different wall types require different fixings, and without the proper support, brackets can loosen over time. We’ve had customers tell us their blinds never sat quite straight, only to find out they’d been anchored into plasterboard with basic screws that weren’t up to the task.

Things to keep in mind before drilling:

• Plasterboard walls need appropriate anchors (basic screws often aren’t enough)
• Concrete or brick requires masonry plugs and drill bits designed for hard surfaces
• Tiled walls need extra care and patience to avoid cracking
• If you’re unsure what’s behind your wall (pipes, wires, or insulation), it’s best to pause and check; better safe than sorry

Our professional installation team knows exactly how to work with different wall types, ensuring your blinds are installed securely and neatly. If you're dealing with an unfamiliar surface or tricky corners, this is one area where expert help really pays off.

Installing Too Low, Too High, or Too Crooked

Getting the height and alignment right can make or break the final look of your blinds. It sounds simple, but without careful planning, blinds often end up mounted too low (making windows feel stunted), too high (leaving gaps for light to sneak through), or slightly tilted (which becomes more obvious with every passing day).

Sometimes it's a spirit level that wasn’t actually level. Other times, it’s down to incorrect bracket spacing or not accounting for how the blinds will roll once fitted. Whatever the reason, even the most beautiful blinds will look second-rate if they aren’t sitting square and at the right height.

How to get it right:

• Always use a level or laser line when marking bracket positions
• For recess fitting, ensure brackets are evenly spaced and aligned across the top of the window frame
• For face fitting, install brackets slightly above the frame to give the illusion of height
• Check for obstructions (like handles or trims) before finalising placement
• Use masking tape to mark positions before committing to holes

A clean, aligned install gives blinds a polished, built-in look. And if you’d rather not juggle tape measures and pencils on a step ladder, our experienced installers can take care of this part for you.

Forgetting About Safety (Especially in Family Homes)

Cords and chains might seem like minor details until they’re within reach of little hands. One of the most overlooked aspects of blind installation is child safety, particularly in homes where young children or grandchildren visit regularly.

Looped cords can pose a serious risk, which is why all compliant window blinds NZ-wide must meet specific child safety standards. These aren’t just suggestions; they’re legally required in many cases, especially for blinds sold and installed in family households.

How to make sure your blinds are safe:

• Use cleats or cord tensioners to secure loose cords out of reach
• Consider cordless options or motorised blinds, which are not only safer but tidier too
• Follow installation guides carefully to ensure compliance with NZ regulations
• If you’re unsure, ask us! We’ll always recommend the safest, most practical option for your space
