Repairs to Aluminium Sliding Doors on a Balcony in Notting Hill

Repairs to aluminium sliding doors in on a balcony in Notting Hill W11.

Double sliding doors that meet in the middle of the balcony. They are not aligning properly and therefore not locking as the locking mechanism and the keeps do not line-up up. 

The runners on one of the doors needs to be replaced. Once that is done the doors can then be realigned.
