Extensions- 21 Sep 2019
Ray has done an outstanding job with the new extension. He has shown great attention to detail and accommodated every request. The result is one that we are extremely happy with. He installed a new bathroom downstairs complete with all necessary pipework and a new utility closet with exits for the washing and dryer. Clearly Ray has a very broad set of skills, from electricity to building to carpentry, plumbing and roofing. He really was the one stop shop to make this extension a reality and has a network of people he can call onto if required. He is certainly someone that takes pride in his work and wants a job well done as evidenced by his work. I recommend Ray without a doubt and I'm sure our paths will cross again. Thank you Ray!

Bathroom Fitting- 9 Feb 2019
Alexandros did an exceptional job with our bathroom. As it was our first major renovation we were very anxious about the whole process but Alexandros made everything very easy and smooth from the beginning until the end. Alexandros has a lot of experience and he is full of ideas and good suggestions. The new bathroom looks amazing and we could not have chosen better than Alexandros. Alexandros was very helpful throughout the whole process. I would highly recommend Alexandros to anyone and we will definitely use his services in the future.
