Mark Taylor in Welwyn Garden City

Extremely poor drainage work leading to foul sewage smell, underground leak causing major damp and mould on the adjacent living room wall. On detection, when I initially called Mark, I was told he is on holiday for 3 weeks. Due to the sewage smell I called the Home emergency to investigate and we were all surprised to find out the toilet and shower pipes were not connected to the main drainage with connecter pipes. This lead to water slipping from in between pipes underground. The toilet pipe was shockingly just placed on top of the main drainage pipe. I messaged Mark sharing the pics of the poorly done pipe connections and the damp wall in my living room. Mark refused to come saying I owed him money. I emailed him back reminding him the last small payment was not made as the work was not completed: 1. The toilets and wash basins in the bathrooms were left loose / wobbly, not sealed or fixed to the wall or ground. 2. New fitted radiators were missing lock shields. 3. For the new boiler fitted, first year free service agreed was not honoured. There was no reply to my email. I called him again recently as I’m still left with a unusable bathroom and was told he does not have time and I own him money. I am now left with no option other than to break and redo my newly done bathroom again to fix the drainage work at my own expense after paying him thousands already.
