Window Lock and Latch Replacement in Dubai

Window Locks and Child Safety in Dubai
Falls from windows and balconies are a real concern in Dubai towers. Restrictors that limit opening to about 10 cm let air in while keeping children safe, and adults can still open the window fully when needed.
Many window lock problems start with the sash, not the lock. If rollers are worn, the sash sits low and the lock no longer meets its keep. We check alignment first so the new lock works properly.
For more child safety, see baby proofing in Dubai. For dropped sashes, see sliding window roller repair, and for doors, lock repair and replacement.

Window Lock and Latch Replacement: FAQs
How Much Does Window Lock and Latch Replacement Cost in Dubai?
Window lock replacement starts from AED 100 per window plus the lock. Restrictors start from AED 80 per window fitted. Prices vary and can change depending on your exact requirements, the materials and access to the property, so the final price is confirmed after we see photos or visit.
How Long Does a Window Repair Take?
Most window repairs, such as new rollers, locks or seals, take one to two hours per window. Glass replacement can take longer if the pane has to be cut to size and fitted on a second visit.
How Do I Know If My Window Needs Repair?
Windows that stick, rattle, will not lock, let in dust, hot air or water, or show condensation between double-glazed panes need repair. Rising AC bills can also point to failing seals.
Can You Repair Aluminium Sliding Windows?
Yes. Aluminium sliding windows are the most common type in Dubai. We replace rollers, locks, handles, brush seals and glass, and realign sashes that have dropped.
Should I Repair or Replace My Windows?
Most aluminium and uPVC windows can be repaired with new rollers, locks, seals or glass. Replacement is only worth it when frames are corroded, bent or badly warped.
