Bathroom Fitting- 13 Aug 2018
Exceeded expectations with a stellar job! It was time for me to redo my cloakroom toilet. I had a clear idea in mind and already chose sanitary, tiles and most of the accessories; however I was unsure about few details such as lighting, external pipes, and how/where to add a small douche without taking away from the look I wanted. Derek quickly understood the brief, and instantly provided me with on the spot feedback and clever ideas and solutions, addressing all of my worries. After our chat, I knew he was the right person for the job. Derek was very communicative throughout the whole process and consistently went the extra mile to make sure every detail was spot-on! His craftsmanship is well above standards; he's meticulous and his problem solving skills are brilliant. Derek is also very personable, dedicated, and I was very impressed with his creativity and work ethic. I highly recommend his services, anyone needing some work done in their house would be lucky to have him.

Gerti completely renovated both of our bathrooms, and the final results were absolutely amazing—exactly what we wanted. He was extremely flexible, offered valuable advice for other aspects of our home, and consistently went above and beyond.
