First off, Allan is a solid guy. Good character. OCD about getting things right. Trustworthy. Cares personally. He is technically astute and is not intimidated by complicated appliances such as Grohe. Secondly, his pricing is reasonable. He will work with you. In my case, over about 5 months, he had about 4 bathrooms, multi valve hansgrohe shower, soaking tub, infinity drain, tankless hot water system, outdoor pvc, rain capture, natural gas conversion, drains for various appliances such as ice maker and air con, and several dishwashers. He dealt with rigid gas lines and worked well alongside GC. No need to concern yourself with warranty because he is a stand up guy and will come out in a moments notice to make sure things are working fine. I dealt with many many trades and he is one of the very few who developed into an all star.
