Conversions - General- 6 Apr 2010
After being let down by our previous builder, shortly before work was due to start, we were informed about this website, and somewhat hesitantly posted our garage conversion and kitchen renovation onto the site. After obtaining quotes from 3 builders, we decided to hire Nick cos of his straightforward and honest attitude to the job. We spoke with a couple of people that Nick had previously done work for, and they were very complimentary, so this just confirmed our decision to hire Nick. We have never undertaken any extensive building work before and were therefore nervous about the work starting, however I can honestly say that Nick was absolutely fantastic from start to finish of the project. Nick and his team were extremely hard working (finished much sooner than we expected), they kept the house as clean as possible when completing such works, and were generally an absolute pleasure to have around the house. Nick's craftmanship is exemplary and was always there to discuss any changes, extras or cut backs when not required. I would not hesitate in recommending Nick to anyone, safe in the knowledge that I know he would do an exceptional job, in fact more than three people have already asked for his details upon seeing the great job that he has completed here!! Thanks Nick for everything!!
