Grand Rapids, MI Thermatru Door Contractors

We can stand behind more parts and for longer than other door companies because we make or specify everything that goes into our door systems. The homeowner has one source, Therma-Tru, to turn to if an issue arises with the door system.¹ Other companies either don't warrant as many parts of the door system or warrant them for a shorter period of time. That could leave the homeowner without coverage and confused about who to turn to if issues arise.
