Martin is certainly the most honest, realistic and trustworthy trades person I’ve ever had the pleasure to work with. We’ve renovated a few properties over the years dealt with dozens of tradespeople, both good and bad and Martin sits at the top of the good pile. He had a passion for the job, charged a reasonable price and showed knowledge and commitment. He deals with all sorts of outside jobs and I will get him back in a heartbeat to deal with anything we need on our land or home. He’s a legend.
