What to Do If Honeycomb Blinds Won't Raise or Lower

Honeycomb blinds stop raising or lowering for a handful of reasons: cords tangle inside the headrail, the cord lock jams with dust and debris, or the fabric cells compress and bind together over time.

Most of these are fixable at home in under 20 minutes.

What You’ll Need

Tools

• Step ladder or stool (if the blind is out of reach)
• Flathead screwdriver
• Needle-nose pliers
• Scissors

Materials / Replacement Parts

• Replacement lift cord (match the diameter to your existing cord, typically 0.9mm or 1.2mm)
• Cord conditioner or dry lubricant spray
• Soft cloth or compressed air canister
• Replacement cord lock (if the existing one is cracked or broken)

How to Fix It: Step-by-Step

Step 1: Release the Tension

Before anything else, take the pressure off the mechanism. A cord lock that’s under tension won’t budge and is often mistaken for broken.

1. Lower the blind as far as it will go, even if it’s only moving an inch
2. Pull the lift cord gently at a slight angle (around 45 degrees from the headrail) rather than straight down
3. Let the cord lock click open before attempting to raise the blind
4. If the blind is stuck mid-travel, try pulling it fully down first, then release and raise from the bottom position

This step fixes the problem more often than people expect. Honeycomb fabric has a tendency to bind against itself when tension is applied unevenly.

Step 2: Inspect and Clear the Cord Lock

The cord lock sits inside the headrail and controls the raise-and-lower motion. Dust, pet hair and compressed fabric fibres clog it over time.

1. Remove the blind from its brackets (most lift off or unclip from a front-mounted headrail)
2. Lay it flat on a table or the floor
3. Use compressed air to blow out any debris from both ends of the headrail
4. Check that the lift cords are seated properly in the cord lock channel, not looped over each other
5. If the lock mechanism feels sticky, apply a small amount of dry lubricant spray and work it in with a flathead screwdriver
6. Avoid WD-40 or oil-based lubricants — they attract more dust and make the problem worse

Step 3: Check the Lift Cords

A frayed, snapped or slack cord is the most common reason a honeycomb blind stops raising entirely. It’s also the most straightforward fix.

1. With the blind flat, identify how many lift cords run through the cells (usually two or three depending on blind width)
2. Follow each cord from the bottom rail up through the fabric cells to the headrail
3. Look for fraying, knots, or a cord that has completely detached from the bottom rail anchor
4. If a cord has snapped, you’ll need to restring it: thread the new cord down through the cell holes, tie a secure knot at the bottom rail, and feed the other end through the cord lock and out of the headrail
5. If the cord is intact but slack, it may have slipped from its pulley inside the headrail. Rethread it through the correct guide and test the movement

Restringing takes patience. Work slowly and keep the fabric flat to avoid pushing the cells out of alignment.

Step 4: Refit and Test Before Calling It Done

Putting the blind back up before testing is how problems get missed.

1. Raise and lower the blind fully three or four times while it’s still on the table
2. Check the movement is smooth and that both sides of the bottom rail rise evenly
3. Refit to the brackets and test again from normal operating position
4. If the blind is cordless, press firmly on the bottom rail as you raise it. Cordless lift systems use a spring-loaded mechanism that needs positive pressure to engage
5. If the blind still won’t raise or lowers unevenly, the cord lock itself may need replacing. They’re inexpensive and usually clip straight in as a direct swap
