To fix cordless faux wood blinds that won't go up, you usually need to reset the internal spring tension. Lower the blinds fully, pull them out at a 45-degree angle, and give them a firm downward tug. If they remain stuck, you may need to adjust the tension mechanism in the headrail.
Blinds that won't lift may have a worn-out spring mechanism or one that is locked in place. Remove the blinds from the window and place them on a flat surface. Look for the pin that controls the tension and carefully twist it clockwise to increase tension.
To fix blinds that won't push up, typically due to a stuck cordless mechanism, fully extend the blinds downward and tug them gently at a 45-degree angle a few times to reset the internal spring. For corded blinds, remove them from the brackets and use a screwdriver to release the locked pawl inside the headrail.

Yes, cordless blinds can almost always be repaired. The most common issues—like blinds extending unevenly, refusing to stay up, or needing a snapped string replaced—can typically be fixed at home using basic tools or by contacting a local window treatment professional.
To fix a stuck blind, first try gently lifting the bottom rail with one hand while pulling the cords straight down and horizontally toward the center with the other. If they remain jammed in the headrail, apply a silicone-based lubricant into the mechanisms.
If your blinds are newer, under warranty, or only need minor fixes, repair is the more cost-effective route. However, if the repair cost exceeds 50% of the price to replace the blinds, it's best to install new blinds.
Releasing a Stuck Cord Lock
Locate the cord lock mechanism inside the headrail where the cords run through a pin. Gently pull the cord toward the center of the blinds to disengage the pin and release the lock. If this doesn't work, a slight tapping on the headrail might jolt the mechanism back into alignment.
Faux wood blinds are a durable, budget-friendly alternative to real wood, but they are significantly heavier, limiting their use on large windows, and may warp or bow under extreme, direct heat. Their dense material also lacks the authentic grain texture of real wood and requires more frequent supporting ladders, resulting in a less "clean" look when closed.
Cordless blinds work with an internal tension mechanism that lets them raise, lower, and stay in place without visible hanging cords.
To raise cordless mini blinds, simply grasp the center of the bottom rail and gently push upward until they reach your desired height. The internal spring tension mechanism will hold them securely in place once you stop pushing.
How long should cordless blinds last? With proper care, custom cordless blinds generally last between 5 to 7 years, though many high-quality faux wood or cellular options can last even longer.
Testing the tension
Lay the blind face down and find the small spring at the bottom of the frame, at the back. The two ends of the cords are secured to this spring. On one side, the cord is secured through a small eyelet with a screw. Loosen the screw, then pull through the cord to adjust the tension.
The average cost of blind fitting in the UK ranges from £20 to £30 per blind. However, you'll also need to factor in the supply cost of the blind itself. The average blind costs somewhere between £30 and £127, depending on the type and size of the blind you choose.

To fix a cordless blind that won't go up, fully lower the shade, then give it a few firm tugs at a 45-degree angle to reset the internal tension spring. If it still won't retract, check for tangled cords in the headrail, ensure the blind is level, or increase tension by turning adjustment screws clockwise.
Fixing blinds that won't go up depends on the mechanism. For cordless blinds, lower them completely, tug down firmly at a 45-degree angle, and raise them to reset the spring. For corded blinds, use a flathead screwdriver to gently release the jammed metal pin inside the headrail.
Most problems with operating cordless shades can be resolved by reactivating the cordless tension device. To do this extend the shade until it is fully lowered then raise the shade by pushing up on the middle of the bottom rail. It may take several attempts to reactivate the tension.
