Recently we were contacted by Mr Cooke from St Austell with a challenge. He had a badly damaged tilt and open window where the only reasonable option was to do a complete conversion. The window itself was also badly damaged and this was a factor in not being possible to refit a complete tilt and open mechanism. We had to firstly support the window and then remove the rusted all round mechanism. After we had removed the mechanism we then removed one of the old hinges at a time and replaced them. The hinges we used as replacements were of a standard butt type as this window would not tilt again.
Once both hinges were replaced, a mechanism was added to the locking edge of the window so it could be operated by the handles as a normal window would the only other thing to do was to add a restrictor. The reason the customer wanted a restrictor is to allow him to have the window partially open as a vent the way it used to be when the tilt function was working.
