A shade that creeps back up on its own, or drops the moment you let go, is one of the most common service calls there is. The good news is that the cause is usually one of a handful of small things, and a few of them you can check in five minutes. Here's how to tell which fault you have and when to stop fiddling and call someone.
- A roller shade that won't hold is usually a worn clutch, a shade that's out of level, or fabric that has drifted off the tube.
- A corded shade that slips is usually a cord lock that has stopped gripping or a cord that has jumped its path.
- A cordless shade that drifts down has lost spring tension or has a lift mechanism that needs adjusting.
- Stop before you force anything. Bent brackets and torn cords turn a cheap fix into a replacement.
- We repair shades and shutters even when they weren't bought from us.
Start by Working Out Which Kind of Shade You Have
The fix depends on what's holding the shade up. So look first. Is there a chain or beaded loop at one end of the top rail? A cord hanging at the side? Or nothing at all, just a bottom rail you pull down and push up by hand?
Those three setups fail in different ways. A chain-driven roller shade relies on a clutch. A corded shade relies on a lock. A cordless shade relies on a spring or a friction brake. Knowing which one you have saves a lot of guessing.
Why a Roller Shade Won't Stay Up
On a chain-operated roller shade, the clutch sits at the end of the tube and is what stops the shade from unrolling under its own weight. When it wears, the shade creeps down a little at a time, or drops when you release the chain.
Before you blame the clutch, check the simple things. Make sure the shade sits level in its brackets and that the tube is seated fully in both ends. A tube that has slipped out of its bracket on one side will ride crooked and won't hold. Then look at the fabric. If it has wandered to one side and is rubbing against a bracket, it will bind and behave oddly.
A worn clutch is not a home repair on most custom shades. It's a part that gets replaced. If the shade holds for an hour and then drifts, that pattern points at the clutch.
Spring Rollers and Pull-Down Shades
A cordless roller shade uses a spring inside the tube. When the spring loses tension, the shade won't roll back up, or it rolls up slowly and sags. Sometimes the spring can be re-tensioned by lifting the shade out of its brackets, rolling it up a few turns by hand and setting it back. If that doesn't hold, the spring is tired.
Why a Roman or Cord-Lift Shade Slips
A shade with a lift cord has a cord lock inside the headrail. It clamps the cords when you pull them to the side and releases when you pull them straight down. Dust, a frayed cord or a lock that has worn smooth will let the cords slide.
The other common cause is a cord that has jumped out of its path. When the cords don't run evenly, one side of the shade carries more weight and the lock can't hold it. You'll see this as a shade that hangs crooked or won't lower all the way.
A crooked Roman shade is often a cord problem and sometimes a fabric one. Fabric that has stretched unevenly or a ring that has come off the tape changes how the load sits. Neither is a five-minute job.
Why a Cordless Shade Drifts Down
Cordless lifts use a spring or a friction brake, and both can lose their grip over time. Heat matters here. A west-facing window in North Texas can run hot enough to affect the fabric and the mechanism, so a shade on a sunny window may wear faster than the same shade in a shaded room.
Some cordless mechanisms can be adjusted by a technician to restore tension. Others need a replacement lift assembly. Either way it's a small job when it's caught early. If the shade has been dropping suddenly, stop using it and have it looked at.
What You Can Safely Try First
- Check that the shade is fully seated in its brackets and that the brackets are firmly screwed in.
- Look for cords that have jumped out of their guides or are tangled.
- Wipe dust from the headrail opening and any visible lock with a dry cloth.
- Raise and lower the shade slowly and watch where it starts to slip.
If none of that changes anything, put the tools away. Prying at a headrail or yanking a cord is how a clean repair turns into a damaged shade. Our guide to cleaning shades and blinds covers safe care if the mechanism just looks grimy.
A Safety Note About Cords
Loose cords are a documented hazard for young children. The federal government has a federal cord safety standard for custom window coverings. If you're repairing a shade and there are small children or pets in the house, this is a good moment to ask about cordless or motorized options. We cover those in our post on cordless and motorized coverings for kids and pets.
Repair or Replace
Sheila will make every effort to repair a shade or shutter, including ones that weren't bought from True Haven. If a repair isn't possible, we can replace it and match it as closely as we can. That's often the better answer for an old mechanism on a shade whose fabric is in good shape.
Blinds and shades typically run 2 to 3 weeks from order to installation when a replacement is needed. That's a normal range rather than a promise, and the exact date is confirmed the day the order is placed.
