When purchasing new blinds for your home, you may have qualms about the installation, but don’t let that stop you from choosing the blinds of your dreams. Putting up shades is much easier than you might think and, with the right tools, anyone can do it. If you’re wondering how to install cellular blinds, our guide can help. 

What Are Cellular Shades?

Cellular shades, also known as honeycomb shades, are similar to pleated shades, but they are made with two layers of material rather than one. These layers are connected at multiple points along the length of the blind, creating tubes of air. 

Thanks to this feature, all cellular blinds, including cordless cellular shades, provide fantastic insulation, ideal for homes in extremely hot or cold climates. Considering between 25 and 30 percent of residential heating and cooling energy use is due to air escaping through windows, this is incredibly valuable for your comfort and utility bills.

Tools You Will Need

Installing cellular shades is surprisingly easy and requires very few tools. Before you gather your equipment, take a look at the instructions for your particular shades. Make sure you have all your tools close at hand for foolproof, swift and easy installation. 

Most cellular shade installations require a:

  • Level 
  • Hammer
  • Steel measuring tape
  • Screwdriver or power drill
  • Pencil
  • Step ladder

How to Start

As with any installation or build, the best way to start is to unpack your shades and all the mounting hardware. Look at your instruction manual and check you have all the necessary materials to install your blinds. 

Lay everything out in the order you will need it, so you don't waste time looking for tools or mounting hardware at a crucial moment.

Mounting Styles

Cellular blinds can be mounted either on the inside or the outside of a window frame. Each style has advantages that are important to consider when deciding on the best shades for you. Interior mount shades sit inside the window frame and have an aesthetically pleasing look most people prefer over the exterior mount variety.

However, inside mount shades let in more light, so, if you’re seeking blinds for bedroom windows, they may be more suitable. Before you order your cellular shades, measure your window. If you’re buying an inside mount shade, measure the width of the window at the top, center and bottom and choose the narrowest number when placing your order to ensure a good fit. 

When measuring for outside mount shades, measure approximately three inches above and below the window and sill to ensure the best fit for mounting hardware and minimum light spillage.

Positioning Your Mounting Brackets

It’s essential to get your mounting brackets into the correct position, or you’ll end up with a crooked blind. For inside mount blind brackets, measure approximately two and a half inches on each side of the window opening and mark the line with your pencil, using a steel measuring tape to ensure each bracket is lined up correctly.

When installing outside mounted shades, place the shade on the wall on top of the window surround in a central position. Use your pencil to mark where the brackets will go, again about two and a half inches from each side of the blind.

Attaching Your Mounting Brackets

Depending on what style of cellular blind you have, screw your brackets directly into the wall or window surround. To make this easier, use a pencil to mark where the screws go and create a starter hole using your drill or by simply tapping a screw gently with your hammer. 

After making your starter holes, fasten the screws securely. If you are mounting directly into drywall without studs, you should use drywall anchors to ensure the wall around the screw doesn’t crumble. Wider blinds may come with more than two brackets for a secure fit.

Fit Your Headrail

Once your brackets are securely attached, the hardest part of the job is over. Attaching the headrail on both inside and outside cellular blinds is incredibly easy. All you have to do is hook them on the front of the brackets and gently push them up to snap into place.

Test Your Shades

The final step in installing your cellular blinds is testing them to see if you can raise and lower them smoothly, stopping them at whatever height you prefer. Take your time lowering and raising each shade, paying attention to the evenness of the movement. 

If they don’t run smoothly, the brackets may not be level. Alternatively, there may be an issue with the blind strings. For instance, they may have been damaged during installation. If you're not sure how to fix blind strings, consult the manufacturer’s instruction manual.

Don’t Be Afraid of Installing Cellular Shades

Cellular blinds are a beautiful and practical addition to any home, providing fantastic insulation and a chic look. Once you know how to install cellular shades effortlessly and are aware of their benefits, you’ll want to put them on every window in your home.
