These homeowners in Diamond Bar were looking for a way to add a room, that would still let them be inside but feel like they were out by the pool. Like most Californians they had built the pool and landscaped to make the back yard of their dreams. Most days it is either too hot or too cold. Diamond bar is a fairly moderate climate; but like most of California, when it is hot it is too hot, and most evenings it is too cold. Interviewing contractors was not an easy task as most companies were proposing adding a "box" type of addition to their home. None of the companies were addressing their main concerns, heat and cold. They found the Four Seasons by Sun Boss website and were very intrigued that the first item mentioned was the high performance glass, as well as the "clean coat technology". In considering an all glass sunroom they really hadn't thought about who would clean all that glass. Four Seasons has always considered all the issues about building rooms out of glass. Naturally the issue of keeping the heat and cold out or in and who will clean the room as well as the concern with breaking a window in an all glass room. Every one of these issues is not only the focus of the design and the performance of a Four Seasons Sunroom, but they are all covered under warranty. A "LifeTime" warranty. Breakage of any glass is covered for 20 years, 100% covered unlike any other warranty in the industry. Needless to say Sun Boss designed the room of their dreams and has incorporated the kitchen and family room into the new sun room. All tied around their beautiful backyard. At night the back yard is illuminated with the pool lights and garden lights that make you feel like you are sitting outdoors....inside!
