Stan was the third handyman to attempt to mend the handle on our back door. He was the only one to a) diagnose the problem immediately and b) not charge an absolute fortune for not doing it!
I asked for an electrician to fix my flickering lightbulb and I was slightly surprised to hear it was the fault of the lightbulb (not a transformer) which he said did not exist with my system. He replaced the lightbult (thank you). Sometimes, however, the light is still flickering but not so much as before. As I have been out a lot this week, I am keeping an eye on it so will be in touch if the problem continues!
