What Makes Our Windows Different?

Our windows are engineered to provide superior performance. Foam insulation provides almost two times the insulation of fiberglass while 100% virgin vinyl ensures your Provia or Pella windows outlast those made out of engineered wood and sawdust. We fusion-weld our vinyl windows to ensure you’re protected against the elements, and offer an easy locking system for your protection. Provia and Pella windows are designed with the St. Louis weather in mind, where we often experience several seasons in one day!

I highly recommend Jonathon Head for all your needs! Honest and knowledgable service along with fair pricing. Excellent scheduling and install (ask for Tom) on basement walk out, sliding glass door. Surpasses competitors.

The STL Windows Direct experience was great! From the initial contact, to the jobs estimate, to the job’s completion. The workers were pleasant to deal with, were on time every day, cleaned up daily and the job was completed on time. We are very pleased with their professionalism!

My husband and I had STL Windows Direct come out and replace our back door this summer (June 2024) and they were great to work with! They got the door installed in 1 day and were mindful of our furniture both inside and out! Our old door frame was rotted so they took time and care to make sure all that rot was gone and the new door would be nice and sealed! Overall, I would definitely be calling STL again for Windows and Doors in my house!

I had STL Windows install a new patio door for my walk out basement and they did a fantastic job! The price was right and they got the job done in one day. It has made a huge difference in my basement temperature. My installer was very personable and went the extra mile to ensure the door was perfect. The owner even stopped by to make sure I was happy with it. I will definately use them for my next project. One of the best experiences I have had with a home remodel project.

Can’t say enough great things about STL Windows Direct! They replaced 2 doors on my house and 1 leading into the garage. I also replaced a bathroom window. Everything was easy from start to finish. Dan B was my dealer and was so knowledgeable, kind and patient with my questions and deciding on the window style, and style/color of door & door accessories. Financing process was very easy and quick. Tom L did the installation and he was professional, knowledgeable and meticulous with everything. He also took pity on me and installed a new Ring doorbell/camera for me. I am so pleased with everything!! Will be hiring them again to replace some siding areas on my brick home. I will add pics later if I can.
