I recently decided to take the 1 day C&G upgrade because I was coming across more and more customers who were having problems with their UPVC door lock mechanisms. I live in a historic town, where most doors I deal with are traditional timber doors, so I have always been comfortable with dealing with door lock issues. As the business has grown, I have been dealing with more customers outside the town who have modern UPVC doors. I have found that the majority of calls are more about the door not shutting because the door is out of alignment. This 1 day course has given me the skills to confidently identify the problem and correct the issue so that the doors shut and lock correctly. This is now part of the services I offer. Before the course, I would normally turn down the work saying that the customer would need a UPVC specialist to sort the job. Now I feel confident to sort out the issue myself. The course is very hands on and practical in that you can practice techniques required to solve problems. I would recommend this course to anyone who wishes to expand their skill set.
