very pleased with our new bathroom, this was a complete renovation, rerouting all pipe work, and electrics. taking down ceiling, removing all plaster from walls, replacing ceiling and re-plastering. bricking up small window, and replacing another window. building new cupboard to house boiler, and replacing soil pipe. installing new bath, shower, W/C, sink, extractor fan and lighting. the work has been carried out to a high standard. Russell and his team, were on site, on time every morning. the work was completed on time, and as per quote. Russell and his team, were friendly and considerate, keeping our house tidy and clean. would i use K J Construction again ? that would defiantly be yes. it can be stressful, finding a good, reliable builder. choosing K J Construction was a very good move on my part. my thanks to. Russell, Mick, and all the team. Dan Leahy
