Hello i have asked some builders/landscapers to put a new patio/paving and some turf/grass in my back garden. I found the people on the checkatrade website and he texted me an estimate. The issue is that he has been twice this week and asked for a deposit on each time despite the fact that the estimate said payment was on completion. He also put a damp proof course around the back which i guess is nice but im not 100% sure this was needed and it wasnt part of the original work i requested. Theres definitely no damp in the house.
It seems that i will eventually end up paying him twice what was in the estimate which will not help my personal finances. He is due to come back next week but im having second thoughts about having him continue as i feel he is taking advantage of me and this is proving to be too expensive.
How can i break this to him, im worried that he may become violent or damage the property. I think legally there is no issue as what he is doing is not in line with the estimate he texted me so if he wants to take me to court this is fine. Im just worried about physical violence or him damaging the property. I just don't feel comfortable . Im assuming he has bought the new paving with the deposit i paid him
Any tips or advice please ?
