Marian's team of builders undertook a chimney removal (external and internal), and complete bathroom renovation. The result is outstanding. They performed all aspects of the work - demolition, wall reconstruction, plumbing, electrical, drainage, lining, tiling and finishing - at a master builder level of quality (I speak as an engineer). The shower area floor tiling is a small work of art. They were extremely efficient in adapting to my design, which evolved slightly over time.
They are probably not the cheapest, and may not be the fastest, as they take time doing things properly. But then a bathroom, with all its plumbing, drainage, electrics etc is not something you want to malfunction later on. If you want a bathroom and associated building works done properly, cleanly, and with a beautiful result, get a quote from Masper.
