Hi, I am not sure if this is the right place to ask these questions. I hired my former neighbour who is a carpenter to fit my new kitchen, he said it would take six weeks and started work on 05/11/21. 5 weeks on and it it nowhere near completion due to him barely working weekdays and does some weekends and evenings as he has a day job. When he said 6 weeks I assumed he would be working everyday. I bought my kitchen from Wren, the larder unit I opened myself to see what it was like from the inside and found the screw to the pull out rack was fallen and the arm that is attached to the door was off. I kept asking my carpenter to check if it can be fixed before installing it as I could ask Wren within 28 days to replace it. But he installed it without fixing it. I finally phoned Wren on the 27 day and they said they will replace the whole larder. My carpenter now says he will charge me extra for replacing the larder as it shouldn't have been opened before it was installed and it was my fault that it broke! Should he be charging me extra for replacing the unit despite me constantly reminding him to check if he can fix it? As he says it's not his fault it was broken. Secondly, it doesn't seems like he will finish the work within the started time as the most he has worked in any given week is 3 days, because of his attitude I feel like telling him that if it goes over 6 weeks I am going to start deducting his day rate by the number of days it goes over, would that be wrong? His quote was just sent via email. Please advise.
