How to Fix Broken Blinds (Easy DIY Repairs for Common Problems)

Damaged or broken window blinds affect the comfort of your space by leaving gaps, poor light control, and an awkward appearance. They don’t completely block the outside views, but it will be difficult to maintain the same level of privacy.

Broken slats will cause uneven light infiltration, which may increase glare on screens. Whereas the broken mechanisms or cords will diminish the look of your window. Fixing damaged parts will cost you less than purchasing a new one. Repair saves you time by letting you visit fewer shops to match the blinds to your interior.

To learn how to fix broken blinds, we will explore the causes and signs of damage and the effective methods for repairing them.

Common Signs Your Blinds Are Broken

Before we learn fixing methods for broken window blinds, you must understand the reasons & signs that prove your blinds need repairing. Once you understand these symptoms, you can get the best idea whether it needs to be repaired or replaced.

• Blinds won’t raise or lower
• Slats are bent, broken, or missing
• Cords are tangled or snapped due to poor handling. Pulling the cords very quickly to open the slats may cause tangling.
• Blinds tilt unevenly

Tools and Supplies Needed to Fix Blinds

Before fixing the damaged parts, you must have the basic DIY tools to complete the process with no distractions.

• Screwdriver
• Needle-nose pliers
• Scissors
• Replacement cords or slats

Besides gathering the necessary tools, follow the safety tips before starting repairs to ensure a safe output. Prepare the area by removing all the furniture or wall hangings near the windows. Then thoroughly inspect the areas to be repaired to save time. For large blinds, get help from anyone to avoid injury or falling hazards.

Identify the Type of Blinds Before Fixing

Blind type matters when you think about the repair of any part. Not every window blind has the same operating mechanism. To know which part is broken, you must be familiar with the type of blinds. Vertical blinds are attached to tracks and operated by chains. While horizontal blinds are dependent on cords and tilting gears to open or close. Roller blind repair requires adjusting the rolling fabric, rollers, and spring-laid pin. In Roman blinds, cords are pulled to stack the folds neatly. Motorised blinds have power motors and are operated by a touch on a remote control.

To avoid mishandling, do not ignore the inside-mount vs. outside-mount considerations. When the blinds are fixed inside the window frame, that is an inside mount. It looks more compact and good for the smaller space to look wider and more open. For the outside mount, window shades are fitted over the wall or outside of the window frame, completely covering the window. This is ideal for maximum light control and privacy.

How to Fix Blinds That Won’t Go Up or Down

Once you know the operating mechanism of every window blind, it will be easier for you to identify the issue. To learn how to fix blinds that won’t go up or down, have a look at the following procedure.

• Inspect the blinds for repair. Check the lift mechanism; if it isn’t moving, there might be debris buildup or a tangled cord.
• For untangling or resetting cords, ensure all the slats are fully open, and the blinds are attached to the brackets.
• In corded blinds, the cord lock mechanism gets stuck and makes the operation of the blinds difficult. The locking mechanism helps your Outdoor blinds to stay at a certain level. When it gets stuck, you can not move your blinds either up or down.

For fixing a stuck locking mechanism, pull the cord to the centre of the window shade at around 45 degrees to open the lock. If the blind is stuck, then slightly push the metal pin in the headrail to unlock it. If roller shades do not retract, then remove it out of the brackets. Roll the sheet manually and re-adjust it in the track. This will reset the spring.

How to Fix Broken or Bent Slats

To repair the broken or bent slats, follow the steps below.

• Remove damaged slats by opening the bottom plug. Then untie the knot to release the damaged or broken slat. Hold the string upward to remove this slat.
• Replacing slats in horizontal blinds is tricky. It is done by taking out the bottom slat first. Start removing all slats until you reach the broken slat.
• Take a spare slat from the bottom and insert the thread into the hole to fix it at the new place.
• To fix vertical blind vanes, you need to open the metal pin at the top rail. It is easier to detach the individual vertical slat.

To straighten the bent aluminium and PVC slats, dip them in warm water or cover them with a wet towel and hit them gently with a hammer. The warmth will let the creased part become straight. For wood & plastic slats, use tape or glue to fix the minor or localised broken part.

Using tapes, glue, bottom slats, and knotting strings are quick & temporary, but these fixes are cost-effective solutions that improve your existing blinds. On the other hand, replacing the entire window shade, fixing a single broken slat, or fixing the mechanism initially costs a lot. But these fixes are permanent and offer durability and efficient performance.

How to Fix Broken Blind Cords

You cannot operate the blinds if the strings/cords/chains are broken, in whole or in part. When the cords have slight damage, these steps will help.

Identifying Cord Damage

See whether your blinds’ cords are fully broken, partially broken, or just frayed. This will help you decide the right method to make your shades functional again in no time. For quick fixes, you can knot the broken ends of the cord and apply super glue on the knotted part. For permanent fixing, you need to replace the cord. To fix blind cords safely, here is the guide.

Step-By-Step Cord Replacement Overview

• Lower the blind fully before removing it from the window frame. For easy & smooth fixing, keep it on a level surface.
• Dispose of the damaged cord by removing the plastic cap from the bottom rail. The cord knots are visible; cut them out and pull out the broken part.
• Slide the new cord through each slat and through the headrail. To thread it smoothly, first secure the cord end using a lighter spark. This will prevent the end from frying during threading.
• Starting at the button rail, move the secure end of the cord up through each slat. Continue passing until you cross the end through the headrail.
• Now, you have replaced the new cord fully. End this task by making a double knot at the lower rail and closing the plastic cap.

For partially broken cords, you can join the end of the replacement cord to the slightly broken section of the original cord. To connect both parts securely, you can use a lighter, then press the connected portion. Then pull the old, broken cord from the upper slide, helping the new cord pass through each slat until it reaches the last top rail.

For roller blinds, if the beaded chain is broken, you can easily connect both broken ends of the chain together using a bead connector. These are easily accessible in plastic and metal materials. Use safety tools or cleats to hold the looped cords at the safest point that is out of reach of kids. The cords may be dangerous for the kids. Try to keep the distance at least 5 feet above the ground while securing the cords on the side of the window blinds. For safety concerns, make sure the furniture or anything else is away from the blinds to avoid pets climbing.

How to Fix Tilt Mechanism Problems

Sometimes, the blinds have tilting problems due to a jammed or broken mechanism. For blind tilt mechanism repair, consult the contractor, who can provide a free repair that is usually covered by their warranty.

• When the wand is moving but fails to adjust the slats, it means the inner mechanism is broken. In that case, a replacement mechanism is necessary.
• If the wand is broken, then replace the tilt wand or tilt mechanism with a new one. To do this, remove the damaged wand by opening the gear that holds the wand.
• Aligning slats evenly before fixing the blinds. For misaligned slats, slide the vanes in the opposite direction. Then repeat it twice until they are in a straight line and moving smoothly.

When to Repair vs Replace Broken Blinds

If the blinds are new and have a faulty mechanism due to broken slats, cords, or chains, then repair is an affordable solution. You can revive their beauty and functionality at a minor cost. But when the blinds are old (approx. 10 years), discoloured, and have severely damaged parts, replacement is a long-term, cost-effective solution. Repairing such blinds will cost you about 40-50% of the price of the new ones. At that time, buying the new blind will provide long-lasting durability.

Maintenance Tips to Prevent Blinds from Breaking

To reduce the expenses on repair or replacement, prevent blinds from breaking. Here are some useful tips that are crucial for maintaining your window treatment for good performance & longevity.

• Use the window shades properly for daily use. Do not open or close them in a hurry.
• Gently pull the cords to avoid breaking or entangling them.
• Regular cleaning & dusting are crucial to prevent debris from accumulating in the headrail or slats. For dusting, soft microfiber cloth is very effective.
• For deep cleaning, wipe off the stains with a damp cloth.
• Safely attach the cords to the wall to avoid cord damage.
• Avoid using oil for the smooth movement of blind parts. Silicone spray is good as it will not attract dust as oil does.
• To extend the blinds’ lifespan, use protective films to prevent fading. Prolonged exposure can damage the moving parts or discolour the blinds severely.

Conclusion

To repair the blinds, first close them and remove them safely from the supporting gear. Then observe the issue and the mechanism of your blind type. Before starting the DIY reset, gather all the necessary tools. By following each step carefully, you can fix broken or misaligned parts and address mechanism issues. Knowing how to repair blinds at home is necessary, but preventing damage is more important. So keep checking regularly for any defects and follow the maintenance tips to save time, effort, and money on repairs or replacements.
