The Patio Enclosures® brand has been a mainstay in the sunroom industry since 1966. Known for their exceptional quality and durability, Patio Enclosures sunrooms have been built on over 250,000 homes across the United States. Owned and operated by Cleveland-based, Great Day Improvements, Patio Enclosures sunrooms are custom-made in our state-of-the-art manufacturing facility located in Northeast Ohio. Every home is unique, which is why Patio Enclosures rooms are custom-made for each specific homeowner. Patio Enclosures builds better products because we control the process from start to finish. There are no middlemen. We design, make, install and guarantee your sunroom. Not only do we extrude our own powder-coated aluminum, but we also cut and temper our own glass giving our customers the most glass per square foot – our Edge-to-Edge Advantage®. You won’t find stock sizes or fillers with our custom-made rooms. Today, we are more than just sunrooms. Great Day Improvements is also the exclusive manufacturer and installer of Stanek brand vinyl replacement windows and doors.
