How does a small family window business grow into a thriving home exterior company offering everything from replacement windows and exterior doors to roofing, siding, and so much more? Thermo-Seal started from humble beginnings in the corner of a machine shed and grew slowly relying on the time-honored principles of keeping God first, practicing the golden rule of treating others as we would want to be treated, quality products, and a great value for the customer. Back in 1991, Titus Hostetler was working hard in the construction industry when he hurt his back.
