After years baking in the hot sun, we decided to look into converting our 300 sq. ft. cedar deck into an enclosed 3 season sunroom. After considerable research, Sunspace Sunrooms in Whitby fit the bill perfectly. Custom fit to our existing deck, the result was a beautiful living space overlooking our backyard that vastly exceeded our expectations. The installer, Dave Bishop, was a true craftsman and took great pride in crafting the room, even suggesting additional touches above and beyond the original plan (at no additional cost) that made the final product even nicer. Sunspace's innovative product line is worth looking into, particularly their unique window systems. Recommend this product and in particular Dave Bishop enthusiastically.
