THEBCO Windows, Doors & Siding

A+ highly recommend. I’ve had Thebco replace 8 openings & 2 exterior doors the past 2 seasons. They will return again this year to update 2 more windows. The product is superior. I have noticed the windows reflect sunlight in summer keeping my house cooler and in the winter keeping cold air out. The install team of Jason & Kyle have been great and I have requested them to return again for next install. Dave Speer is great representative to discuss options when deciding what windows & doors, colors to choose. I switched some areas from double hung to awning style & crank out widows side by side to awning allowing much better scenic views. The storm door I have now is such a better upgrade from what I had previously. I am very satisfied with the quality of product and value when com

Ken and Mark did an amazing job replacing our sliding patio door!! They were very efficient and did the job in less than a day. We love the look of our new door. We also want to shout out Dave our fantastic sales person who was very helpful throughout the entire process. Thanks!

I’ve resorted to leaving a one star review. I have been waiting since July 2025 to get a cracked window replaced. The window has a lifetime guarantee. I have called once a month since July checking on the status. Dave in production always takes my calls so in terms of communication, they are responsive. The delay impacting us has been blamed on the manufacture. During my December phone call, I was informed the window would be delivered to the warehouse on January 9 and Thebco would call me to schedule the replacement. No Call. No word of any kind. It appears the lifetime warranty means YOU will wait a lifetime for your window to be replaced. This is really unbelievable that a local company would be satisfied with working with a manufacturer such as this when it impacts the customer so nega

Jason and Jacob Schmidtke are real craftsmen! We had them replace the windows in our foundation. Everything, from the flashing to the caulking, is impeccably done. We will definitely go with Thebco again for our future window projects!

Love my new door! It looks great and I can tell it helps with keeping the cold out already. Holden was polite and professional. He applied new insulation around the door frame, cleaned up as he completed each step, and was able to remove my existing screen door and framing without damaging it so that it could be reused.
