Blinds come in all kinds of shapes and designs, whether it comes to the mechanisms they use or the blind slats and their style. You can also classify them by materials – such as wood blinds or aluminum blinds, not to mention the orientation – horizontal or vertical blinds. While extremely versatile, they also go through a lot of hassle and stress.

Sooner or later, you will inevitably need to learn how to fix blinds. Your window coverings will fail, meaning they may stop working or they may look damaged. Luckily, there are a bunch of solutions you can apply, regardless of the type of blinds you have. Here are some of the most common issues and their solutions.

Here are the 9 Issues and How to Fix Them


When They No Longer Lower – Suitable For Wood Blinds

This issue is connected to a few different parts and will require going through a few steps. The first step involves holding the lift cords at the same level with the head rail. Pull gently, so the cord lock is fully released. You do not have to go too far. Once released, the lock should allow your blinds to go down again.

If this quick fix does not solve the issue, you will need to remove the blinds. Find the cord lock mechanism by following the lift cords – they are supposed to go through it. The system comes with a pin. Get a flathead screwdriver and turn it perpendicular to the rail. Slightly push the pin and the mechanism should be unlocked. The moment you let the pin go, slats will lower straight away.


Dealing With Wood Window Blinds That Do Not Tilt

The tilt rod is not perfect – it goes through so much movements that it may lose its efficiency. Most commonly, it will disconnect from the whole mechanism associated with the head rail – at this point, the slats will no longer tilt. The mechanism will move, while slats show no connection whatsoever.

Make sure you remove the blind for easy access to the mechanism. Look at the head rail and spot the metallic rod running through the entire rail. This way, you can find the housing that hosts the tilt mechanism. Push the end of the road where this mechanism is located – you have to do it gently though. This way, you will reach a very secure positioning.

Tilt Mechanism Issues – How To Replace A Tilter

Take the blind out – if the system has a wand, remove it. If there is a cord tilt, let the tassels off. The end of the head rail should feature an end – metallic or plastic. Take it off and slide the road out – you only want the tilter to be clear. Assuming that you already have a new tilter, simply replace it and put it back in place.

The ideal position implies the flat portion of the tilter lined up with the same area inside it. You will have to play with the shaft a little until you reach the perfect position. You can then put the rod back through it and throw the end cap on.


Blind Slats, Cellular Shades And Uneven Hanging

This issue is relatively common, but also easy to fix. It happens when the cords are caught in the actual rail. The main cause is in the C clips, which are not even over the tilt rod. The solution is quick – unhook the cording, then play with the shade a few times to see the results. Make small adjustments as you consider.


Noisy Cellular Shades

Cellular shades are known for becoming noisy every now and then – the problem is more common in large shades. It may also affect mini blinds. As you may have noticed already, there is a small plastic part that prevents the long metallic strips from rubbing against the head rail. When this part loses its original position, your blinds and shades will go noisy.

Locate this plastic part and push it to the end to avoid noisy blinds.


Long Cord Controls In Cellular Shades

You have not done anything wrong if the cord control feels too long. Instead, it is a matter of small adjustments. Locate the small cord – it usually goes into the cord collector. It should have an upper knot – find it and untie it. You will then be able to push the ball up to the optimal position – retie the knot once you are done.

It might be tempting to cut the excess window shade cord – do not. Simply give it a bit of time – you might need it longer later on.


Frayed Cord Loop Issues

The returns are either too short or too long – it sounds like a dead end, but you can fix it without having to improvise.

Initially, you should get rid of the control end cap. Look at the head rail and the top part should have a tab. Lift it and you can release the cap then. It should not require any effort whatsoever. Once done, you can find the rayed cord loop. Remove it – simply lift the cord, then turn the mechanism a little. The rotation could be a bit difficult, but you can use a screwdriver – just push it into the middle part of the mechanism.

Gently place the cord into a tooth on the gear. This is how you start a new cord loop. Rotate the loop, then put the control cap back.


Restringing Aluminum Blinds

Cords can cause lots of trouble, but you can still fix the issue without too much effort. Inspect the cords. If they are not broken, your fix is much easier, as you will not need to remove the blade. Instead, get rid of the ladder cap – under the bottom rail. The cord ends should be accessible now, so feel free to pull them a little.

Grab some scissors and cut the old cord – right over the knot. Weld the new and old cord together using fire – a lighter will do. Roll the mixing part a little for extra smoothness.

You will then need to pull the tassel – do it from the cord lock direction – to the left. The new cording will fit into place – tie a knot at the end, then put the tassel back in.


How To Replace Aluminum Blind Slats

Replacement is usually a last resort. Pretty much anything can be fixed – you can play around with cords, mechanisms and even a bent blind. But then, replacement may still be required at some point – you will not need new blinds or a new system – just some extra slats for replacement.

Take the ladder cap out – it is located by the bottom rail. You will be able to spot the ends of your cords – pull them out a bit. Cut a cord above the knot, then take it through the damaged slat. Remove the slat, throw a new one in – make sure you install it correctly, as a perfect alignment is mandatory.

Put the cords through the bottom rail, tie them and put the cap back in.

Frequently Asked Questions

Still unsure about how to fix blinds?

Can you fix broken blinds?

If blinds are broken, you might need a new system. You can, however, replace a few broken slats. But then, you have to consider value for money. If there are more broken slats than good slats, a brand new blind might be a more cost efficient option.


How do you repair window blinds?

It depends on the problem. The good news is you will not really require any tools – you might need a screwdriver though. Other than that, most operations are intuitive and require no experience whatsoever.


How do you fix blinds that will not go down?

This issue affects the cord lock. The easier option implies aligning the lift cords and head rail before pulling. If it does not work, take the blind out and push the pin in the cord lock mechanism. It will relax the lock and your blinds will work again.


Can you replace a single-blind?

Absolutely, yet it depends on what system you have. Classic blinds allow replacing a single unit without too much hassle – more sophisticated systems might be limited.


As a short final conclusion, you do not have to be a genius to look after your blinds. Blinds, slats and mechanisms will not last forever – you use them a few times a day, so they obviously wear out. The good news is there are ways to fix them, regardless of the problem.


Each problem has at least one solution, yet there are situations when replacing the whole blind might be a better choice. It depends on how severe the problem is – sometimes, replacement parts can be pricey, not to mention the time you waste. In this case, a new system could be better.
