“I had the pleasure of having Mr Kennedy for the renovation of our master bathroom and bedroom suite in 2014. I can recommend him highly and without reservation. Throughout the course of the renovation, Mr Kennedy was a consummate professional. He was accurate in his initial assessment of the scale and cost of our project.”
