Double Glazing Repairs
Double Glazing Repairs Across Deal & East Kent
Fast, professional repairs for misted, stuck, or faulty window and door units
If your double glazed windows or doors are misted, jammed, or not locking properly, we offer a reliable and cost-effective repair service across all CT postcodes.
At Castle Locksmiths, we fix the problem without pushing you to replace the entire unit. Whether it’s a small blown pane or a failed mechanism, we’ll sort it — quickly, cleanly and with minimal disruption.
Common Issues We Repair
- Misted or “blown” sealed glass units
- Jammed or stiff window handles
- Dropped or misaligned doors
- Broken window hinges or friction stays
- Failed multipoint locks or door gearboxes
- Seals and draught-proofing issues
- Sticking patio and bifold doors
If a window or door is no longer functioning as it should — or is compromising your security — we’ll get it back to working order without the cost of full replacement.
Types of Units We Work On
- UPVC windows and doors
- Composite doors
- Aluminium framed double glazing
- Patio sliding doors
- Bifold doors
- Tilt-and-turn window systems
Why Repair Instead of Replace?
In most cases, the issue is isolated to a part (like a hinge, lock, or the sealed glass unit) rather than the entire frame. Our repair-first approach saves you time and money by replacing only the faulty component — not the whole window or door.
