I have been buying from Clera for the last 3 years, and am always satisfied. The staff is all very friendly and takes the time to get to know you. Most contractors are only concerned with getting the job done quickly so they can get paid. I never feel like a stranger when I go to Clera. I have had them install 3 windows in my living room, as well as my back door. The prices are great and the quality is excellent. I like the fact that I can get everything I need from one company. They make, sell, and install all of their equipment. Not many companies can provide this service.
