Before ➡️ After on this upgrade 👀

We supplied this beautiful sliding glass door with transom for a recent project and it completely transformed the space!

The added height brings in more natural light, opens up the room, and creates a clean, seamless connection to the outdoors☀️

This install was completed by our team over at , making it a perfect example of how our two companies work together to bring projects full circle from product to installation.

At Diligent Window Supply, we supply a wide range of windows and doors just like this. Whether you’re a contractor or homeowner, we’ve got the inventory and the right teams to help get it done.

The homeowners were thrilled with the final result and it shows💥
