Mark and Darren are an absolute breath of fresh air and a pleasure to do business with. They are polite, helpful, hardworking, honest and trustworthy. Mark Harrison Builders recently completed works on the sympathetic renovation of my period cottage including building a brick porch, rebuilding a single story side extension with stone steps, replacing a stone fireplace, replacing stone window sills, chimney work plus the installation of new drainage. The standard of work is absolutely superb and looks fantastic. I can highly recommend this father and son team.
