Double-Hung Window Won't Stay Up? Here's the Fix for Sash Cord & Spiral Problems in Sydney
Does your window slam shut the moment you lift it, or refuse to budge at all? A double-hung window that won't stay up is more than an annoyance—it's a safety hazard and a drain on your energy bill.
Why This Matters
- Safety risk: A dropped sash can injure fingers or damage frames
- Energy loss: Gaps let in cold air or hot drafts, spiking power bills
- Security: A window that won't lock or close fully invites intruders
Common Causes
1. Broken sash cords
The counterweight system fails, leaving the sash unsupported.
2. Worn spiral balances
Springs lose tension, making the sash slide down.
3. Painted-shut frames
Layers of paint glue the tracks together.
4. Misaligned pulleys or tracks
Years of movement bend or wear components.
What You Can Check
- Gently lift the lower sash—if it drops instantly, the cord or spiral is likely broken
- Look for frayed cords or missing weights in the side channels
- Listen for grinding or squeaks that signal bent pulleys
Professional Repair
Replacing sash cords or spiral balances requires removing trims and glass. Incorrect tensioning can break the new balance or the timber frame.
A professional repair is safer and faster—most jobs take 60–90 minutes per window.
Why Choose Professional
- Proper tools and experience
- Correct tension adjustment
- Workmanship warranty
- No risk of frame damage
