Step by Step Guide for Replacing a Louvre Blade on Narrow Louvre Doors.

Article by 

This guide is for replacing slats/ blades on louvre doors with widths ranging from 300mm to 450mm. For our guide on replacing louvre blades on louvre doors that are 457mm and wider please go to: Guide 1.

So you’ve decided to incorporate stylish louvre doors in your home. But what do you do if you’ve ordered a brand new louvre door and found that a louvre blade has been damaged during transit? You might already own a louvre door and found that over time the louvre blades need replacing. Or you’ve had an accident that caused a louvre blade to break.

You’ve now got to go through the trouble of finding a replacement door. Or do you? Because of the way our louvre doors are manufactured placing individual louvre blades without replacing the entire door is possible. Even better, this is not as difficult a task as you might think so someone lacking DIY experience can do it.

You now need some replacement louvre blades. The length of the replacement blades required is determined by the width of your door. Should you have purchased your louvre doors from Simply Shutters, then we will be able to supply you with the correct sized replacement blades based on your door size. *

Take a look at our step by step guide on how to replace a damaged (or warped) louvre blade on a louvre door. To carry out the replacement you will need the following:

Pliers (long nose pliers are ideal).
Your spare louvre blade/s.
A little bit of time.
Enough space to be able to work on the door.


Use long nose pliers and grip the louvre blade that you want to remove. Take care not to scratch or touch the louvre blades above and below the one you are taking out. If the louvre blade is already snapped then go straight to steps three and four.

Using the pliers twist the louvre blade until it snaps.

The snapped louvre blade should now be in two pieces. As it is not glued into place you will be able to remove the blade from the frame of the door without difficulty. Remove both broken sections of louvre blade.

Once the blade has been removed offer the replacement blade into the empty slot.  Push the blade all the way into the slot.

As narrower louvre blades do not provide much flexibility you will need to trim/shorten the opposite end of the blade to be able to ease it into position. Do this by using the stile (side rail) as a guide. Make a mark on the louvre blade with a pencil to identify how much you need to trim off the blade.

Using a small saw or a Stanley knife trim the louvre blade down to the correct length.

Once trimmed offer the louvre blade into position on one side.

Using a small hammer gently tap the louvre blade on the opposite side until it is securely in position at one end. Be careful not to be too rigorous as you can cause damage to the blade.

Using your hands ease the remaining edge into position from the front and back of the door. Should you have difficulty in getting the remaining end into the slot, remove the blade and trim the corners slightly. Then repeat step nine and ten.

*If you have purchased louvre doors from another supplier and whilst we shall try to be as helpful as we can, it is not possible for us to advise on the louvre blades required. We should just mention that this step by step guide applies to Simply Shutters louvre doors only. There are many differences between door manufacturers so the advice given here might not apply.
