JER Builders carried out a Single Storey Extension onto the rear of my 3 bedroom semi-detached house in Garthamlock, Glasgow. The Quality of work was first class, they also made a few suggestions during the building stage which were then incorporated and, with hindsight, have really improved the final product. JER Builders initially advised us that the build would be around 6 weeks, however, once they started, they got through it a lot quicker than I had originally anticipated. The total build was complete just short of 5 weeks. All trades seemed to work in great harmony and were very friendly throughout. I would say Barry's strengths are his attention to detail, punctuality, and his knowledge of Construction. He is also continually promoting the importance of maintaining safe working practices to all his tradesmen.
