Mariusz came to give us a quote for complete strip out and refit of small bathroom. We already had an idea of how the new bathroom should look and had chosen almost all the new fittings, etc. Mariusz suggested a completely new layout, which we would never have thought of and many different fittings. We decided to go with Mariusz's layout and many of his suggestions for the fittings. The finished bathroom is absolutely outstanding and beyond our expectations. Mariusz is truly a master craftsman.

Chris and John and crew were hard working and brilliant. They turned up on time and made light work of putting in double steels making sure everything was done. When building control requested added work, they had no problems getting it sorted. Hard working team cleaned up each evening. Great job. Price was reasonable.

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
