Daniel provided a competitive quote. I wanted Howdens kitchen and he allowed me to directly deal with Howdens. So in effect I paid the Howdens trader price. The best part was for him to suggest some additional work which made a lot difference. I really appreciate him for that. He charged extra but it was worth it. Daniel and Team worked very professionally and finished the work as agreed. The most important is that Daniel is a good man. I will definitely call him for future work. Highly recommed
