Our driveway spotlight sensor stopped working - replacement spotlights, new stronger cable fitted, replacement driveway wall mount lights, disability ramp made and driveway washed. pretty straight forward. Sam bought the correct lights, extended cable and the sensor with his electrician from B&Q. Removed and replaced removed all the rubbish, respected our property gave the driveway a wash no hassle - left them to do their work and it was done. I would recommend using them they do what you want and how you want it - He does give you his opinion though up to you if you want to take it or not. happy to use them for further jobs

I needed one wall of living room plaster called Craig and he made the whole process so easy, he came round to give me a quote. Compared other workmen and craig was very competitive, he made the whole process easy, I was going to decorate the room myself but Craig put me at so much ease, that I gave him the whole job of plastering and decorating the room. I was worried that I wouldnt get the room done by Christmas. He promised that he would get it done. He was very prompt and the job got completed in the promised time frame. And I was very happy with the result
