Welcome to our website. My name is Dennis Caswell, owner-operator of Glas-Tek Windshield Repair in St. Louis, Missouri. I began my windshield repair business a little over ten years ago and you could say I have been successful at it. To date I have done over $850,000 in windshield repairs and have the records to prove it.

I had to learn by trial and error which tools and resins work and don't work for me. I have spent well over $6,500 in equipment and resins from many of the top windshield repair companies in the United States to determine which technologies work the best.

Come and learn from my experiences on how to manage and operate your own windshield repair business successfully!
