Latest review:
I wanted to replace an old brick wall in my front garden with railway sleepers. I had some idea on how I wanted it to look, but I was very undecided: vertical, horizontal, staggered or squared?. When James came around he made clear suggestions on how make it look nice, simple and within budget. He explained to me what the work involved and showed me some pictures of a previous job he had done so I had a clearer idea. I had to go out the day he came to do the job but he made sure we both were on the same page and he would meet my expectations, and I wasn't disappointed when I came back home. I contacted him afterwards to check details about the look and maintenance of the sleepers and he always replied promptly. I would definitively recommend James.
