Mila Coldseal gearbox replacement in Hexthorpe

An elderly couple in Hexthorpe, Doncaster, contacted SF Locksmiths when they could no longer lock their front uPVC door. The locking mechanism had been troublesome for some time. It had now failed, leaving their home insecure.

Repairing an older Coldseal uPVC door

The property had an original Coldseal uPVC door, believed to have been installed before 2003. The manufacturer later ceased trading in 2004, as documented by British Glass.

Our inspection identified a failed 35mm Mila Coldseal gearbox inside the original multipoint locking mechanism.

We replaced the Mila Coldseal gearbox with a genuine Mila replacement gearbox. This allowed us to retain the original locking strip instead of replacing the complete mechanism or fitting an inferior copy.

We also fitted new security door handles to improve the entrance’s appearance and security.

The result: The existing front door now locks and unlocks effortlessly. The couple can secure their home again without struggling with the handle.
