Step-by-Step Guide: How to Install Blackout Curtains Over Blinds

One common challenge many homeowners face is balancing the functional benefits of blinds with the superior light-blocking ability of blackout curtains. You may have blinds already installed, but desire the added darkness that blackout curtains provide. This blog post will guide you through the process of installing blackout curtains over your existing blinds, including both drilling and non-drilling options. We'll take you step-by-step, from assessing compatibility to selecting the right hardware and, finally, the installation process itself.

Assessing Compatibility: Determining if Your Blinds Can Accommodate Blackout Curtains

Not all blinds are created equal, and not all are compatible with curtains. The types of blinds, their size, and how they're installed can all affect whether you can successfully install blackout curtains alongside them.

Blinds generally fall into a few categories, including Venetian blinds, vertical blinds, and roller blinds. Venetian and vertical blinds usually have enough space to accommodate curtains, while roller blinds may be trickier depending on their size and installation.

Key Factors to Consider Include:

  1. Space: There should be enough space between the top of the blinds and the ceiling or window frame to install a curtain rod.

  2. Protrusion: Blinds that protrude too much from the wall may interfere with the hang of your curtains.

  3. Window depth: This is particularly important for inside mounts, as you'll need enough window depth to accommodate both the blinds and the curtain rod.

Step-by-Step Installation Guides to Hanging Blackout Curtains Over Blinds

Curtain Rods (Includes Drilling) 

The way you mount your curtain rod—inside the window frame, outside on the wall, or on the ceiling—will depend on your specific window and blind setup. Inside mounts can be a sleek option, but require sufficient window depth. Outside mounts are more forgiving and versatile, while ceiling mounts can add height and drama to a room, but may require more complex installation.

Before you begin, gather all the necessary tools and materials. These typically include a drill, screws, a level, and your chosen curtain rod and blackout curtains.

  1. Measure and Mark: Measure the height where you want the curtain rod to be and mark the points for the brackets. Ensure these points are level.

  2. Install the Brackets: Using the drill, install the brackets at the marked points.

  3. Hang the Rod and Curtains: Place the rod on the brackets and ensure it's secure. Then, hang your blackout curtains according to their design—most have either rings, grommets, or a rod pocket.

  4. Adjust as Necessary: Check how your curtains hang, and adjust the length or position as needed.

  5. Maintenance: To keep your blackout curtains looking and functioning their best, clean them regularly according to the manufacturer's instructions.

Accessible No-Drill Options: Suction Cups 

Some windows are not compatible with curtain rods at all, in which case suction cups may be a good affordable option. Suction cups offer a simple and effective solution for hanging lightweight curtains without damaging your walls. They work by creating a vacuum seal on a smooth surface, providing a sturdy hold for your curtains. Not all suction cups are made the same. We recommend investing in high-quality suction cups that will be able to hold the weight of blackout curtains.

To install blackout curtains using suction cups:

  1. Clean the Window Surface: The suction cups will adhere better to a clean surface. Use a glass cleaner to clean your window, then dry it thoroughly.
  2. Attach Suction Cups to the Curtain: Attach one suction cup to each top corner of the curtain. Some suction cups come with hooks or clips to hold the curtain.
  3. Press the Suction Cups onto the Window: Press each suction cup firmly against the window until it sticks.
