Fatjon / Tony and team did a fantastic job decorating my house, getting rid of damp and giving my front garden a completely new look. They re built wonky walls, rendered them and laid some amazing tiles giving an original Victorian look. Communication was excellent and there were no surprise / hidden costs at the end. All the guys at Bardhi construction were super friendly and extremely respectful of my house. They cleaned up every night and took great care of my property. I highly recommend :)
