For over 80 years, Thornton & Grooms has been a fixture of the metro Detroit community. When a furnace breaks down in the dead of winter or a frozen pipeline cuts off water to a home, people turn to us for help. We truly care about helping people — our customers, each other, and our community. The technician or plumber who comes to your home is a professional in attire, experience and character. Every employee we hire-from our repair specialists to our customer support team-has had a full background check and drug test prior to employment with Thornton & Grooms.
