Replacement Window Company Expands to Siding, Doors, Roofing and More

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.

We Started Out as a Window Assembly Company

Back in 1991, Titus Hostetler was working hard in the construction industry when he hurt his back. As the years went on, he knew that his construction job was too physically demanding for his back, so he began looking for something else within the industry that would help him make a living. Replacement windows piqued his interest, so Titus began assembling pre-fabricated window kits in the corner of his machine shed. He and his wife worked evenings and Saturdays and built the business little by little. We are based in Brookfield, MO, but we serve the following communities and surrounding areas:

  • Columbia, MO
  • Kansas City
  • Kirksville
  • Chillicothe
  • St. Joseph
  • Hannibal
  • Maryville
  • Moberly

Quality Drove Us to Improve Our Windows

After about a year, they decided the quality of the windows they were assembling wasn’t good enough. Titus used his construction knowledge to build a better window and they started to manufacture their own vinyl windows. They were still outsourcing the glass and realized that there were too many warranty claims for their liking. Again, Titus took matters into his own hands and integrated a glass shop into his business. Everywhere they saw a need, Titus found a way to provide a quality product from exterior doors to siding, to roofing and more. Eventually, they added a shed, then another larger outbuilding, and the business just kept growing.

A Family Run Home Exterior Company

The reason the family business kept growing, not surprisingly, was because they had a high quality product and word got around. Today, Thermo-Seal continues to be a family run business and now offers every kind of exterior home product including replacement windows, exterior doors, siding, roofing, garage doors, decking, fencing, sunrooms, insulation and more. For quality products, you can’t beat the value of Thermo-Seal.
