Universal Windows Direct is a Great Day Improvements brand.

Since its inception by co founders William Barr and Michael Strmac in 2002, Universal Windows Direct has lived by the philosophy of CANEI – “Constant and Never Ending Improvement”. This philosophy holds true in all aspects of our business, from sales and marketing to installation and service and has catapulted UWD from a small, local home improvement company to one of the largest exterior remodeling companies in the country. Universal Windows Direct of St. Louis opened in 2017. We think our company’s history speaks to this goal and to the power of what we can accomplish by never settling.

Using methods developed generations ago, we can hand shape wood into many forms. Adapting the old methods to modern applications.
