What Clients Say About Us?
Simon & Jody, Battersea, London
“We used Brightmaster for a loft conversion, mansard extension and remodelling of our first floor, which involved turning a spare room and small bathroom into a large bathroom with space for a dressing room. Mariusz and his team were excellent. Everyone that worked on the project demonstrated real care and attention with a genuine pride in what they were doing. Corners were never cut and Mariusz ensured good quality materials were always used. The finished product is fantastic. We are so pleased with what we have. People have commented that the exterior of our home looks like the loft conversion and mansard were built as part of the original 19th century house. We would be happy to recommend Mariusz to others.”
Jose Valdi, Kensington
“The project was finished within the agreed budget and timescale and I am extremely happy with the result. They paid particular attention to detail and also kept all areas clean and tidy at all times. Once the works were finalised they cleaned all the areas of the apartment they had used and the result was outstanding. I would recommend BrightMaster to conduct any building projects. I enjoyed working with them.”
