DIY blackout blind installation

What you need to know

Installing blackout blinds yourself can be a cost-effective way to control light in your home, but it requires precision. A small miscalculation or improper mounting can lead to gaps, reducing their ability to block out light completely. If you're considering a DIY approach, it’s essential to be aware of potential pitfalls and how to avoid them.

Common mistakes to avoid

Incorrect measurements

Accurate measuring is crucial. Even a small miscalculation can leave gaps at the top, bottom, or sides of the blinds, allowing unwanted light to seep through. Measure twice before cutting or purchasing your blinds to ensure a precise fit.


Improper mounting

There are two main installation methods: inside mount and outside mount.


  • Inside mount: The blinds sit within the window frame, creating a sleek look. However, if not measured correctly, small gaps can appear along the edges, reducing blackout effectiveness.
  • Outside mount: The blinds are installed over the window frame, covering more surface area and preventing light leaks. If maximum blackout is the goal, outside mounting is often the better option.


Light leaks

Without proper installation, gaps may appear around the edges, especially with inside mounts. Light leaks can be frustrating and may disrupt sleep, especially in bedrooms or media rooms.

Dealing with light leaks in DIY installation

Even if you've installed your blackout blinds yourself, you might notice small areas where light still seeps through. Here are ways to reduce these gaps:

  • Opt for an outside-mounted blackout blind

    This provides greater coverage than an inside mount and is often the best option for complete blackout. Ensure the blinds extend beyond the window frame to prevent light from creeping in.

  • Blackout curtain overlays

    If small gaps remain after installation, pairing blackout blinds with blackout curtains can help create a layered effect that blocks out any remaining light.

Professional installation

Is it worth it?

If you want a flawless, light-blocking result without the hassle of DIY installation, hiring a professional may be the best choice. Professional installation ensures precision and durability,  well the option for custom side channels and motorisation.


Benefits of professional installation:

  • Custom fit

    Our experts take exact measurements, your blackout blinds are then made to order for your windows, ensuring a perfect fit with no light leaks. Even tricky window shapes, like bay or arched windows, will be measured and fitted with precision.

  • Option for side channels

    Side channels, which block light from the edges and create a complete blackout effect. An expert ensures they are aligned perfectly and flush against the window frame for the best results.

  • Motorisation expertise

    At Waikato Shutters & Blinds, we use high-quality, proven technology and software to motorise your blackout blinds. Expert installation ensures correct wiring, smooth operation, and seamless integration with home automation systems.

  • Better sleep quality

    If you’re after blackout for the sleep benefits, it’s important to have complete darkness for uninterrupted, high-quality sleep. Professionally installed blackout blinds ensure a precise fit with no gaps, creating the perfect sleep environment. By eliminating light leaks, they help regulate your body’s sleep cycle, making them ideal for bedrooms, nurseries, and shift workers.

  • Warranty and long-term support

    Many professional installers offer warranties on both the blinds and installation, giving you peace of mind that your investment is protected. If any issues arise, you’ll have access to expert support.

Professional installation

When should you opt for professional installation?

While DIY installation works well for some homeowners, certain situations make professional installation the better choice:

  • If you want the best possible blackout effect

    We offer the option of side channels, which are essential for achieving 100% blackout. Side channels block light from the edges of the blinds, creating a flawless light-proof result.

  • If you have hard-to-reach windows

    Skylights, bay windows, and extra-large windows require special mounting techniques, which our experts can handle with ease.

  • If you want motorised blackout blinds

    Our professional installers use high-quality software and technology to motorise your blinds, ensuring seamless integration with your smart home system.

Additionally, they guide you through the setup process, showing you how to easily control your blinds using Google Assistant, Alexa, or other automation devices.

  • If you’re installing multiple blinds

    For homeowners looking for a consistent and polished look throughout multiple rooms, professional installation guarantees uniformity.

  • If you want high-quality blackout fabrics

    We offer a range of premium blackout fabrics that provide complete light blockage, regardless of the blind colour. Fabrics available on the DIY market may not match the longevity and quality that a professional installer can provide.

Motorisation

Motorised blackout blinds provide the ultimate convenience, allowing you to control light with the touch of a button, a smartphone app, or even voice commands.
