Extensions- 8 Dec 2017
We couldn’t be happier with the professionalism and quality of workmanship from REA Construction. The project was delivered within budget and on time. We lived in the property during the work and we, our neighbours and the site were always treated with the utmost consideration. There were almost no hitches and, when they did occur, they were dealt with immediately and thoroughly. Our project team, led by Kristjan and Besi, were universally hardworking, organised and produced work to an excellent standard. Communication is great, the people are wonderful. Renato was someone I felt I could trust from the moment I met him and he never let us down. He and everyone at REA genuinely care about what they do and that their customers have a happy experience. We certainly did and would have no hesitation recommending them to others.
