John Philips, Samuel and one more guy whose name I cannot remember did an amazing job at my house on Feb 15. They were efficient, very pleasant and courteous. Dan, at the Port Perry location should be pleased to have these guys working for him. Please ensure they are advised that Barry from Pickering gave this feedback.
