Greater Pittsburgh Location Overview
Great Day Improvements has resided in this same location and served Pittsburgh and the surrounding regions including West Virgina and parts of Ohio since 1983.

All of our products are engineered, manufactured and installed by our own employees. We do this simply because it gives you, the customer, only one entity to deal with now and in the future on your project. The total combined experience of the Pittsburgh team is over 130 years. This explains the longevity of the company, the satisfaction of our customers and the quality of our products as well as the excellent company/employee relationship that exists.

But we are now so much more than just sunrooms- we now offer Stanek Windows and Doors. Come check out our showroom and see what's new!
