I have paid a tradesman to replace a garage door, it’s actually for my brother who is in hospital long term and I am helping to get his home ready for him to move back in. So far I have paid £600 deposit over 3 weeks ago and signed a contract ( come to think of it I have nothing signed from him) which commits me to paying in full within 2 days of the fitting. He said last week he’d fit this week and would be in touch soon to confirm the day, so I could go over and check before making final payment. I have texted today at 9 am to check the date but no answer. This might all be innocent but my gut feeling isn’t good. I did check if he had any CCJs and the website said not. What can I do if no communications? Letter before action? Threaten small claims court? Any advice on how to proceed would be really appreciated.
