Different Types of Windows and doors for Your Home in Stockton, CA

There are plenty of things to consider before you move forward with windows replacement and retrofit installation for your home. Are you interested in a casement or a picture window? Would you like to go with Low-E, dual or triple paned glass? Our professional employees can walk you through information about both U-value (your window’s resistance to heat loss) and solar heat gain coefficient (SHGC), which measures the level of heat that enters through the glass and into your home. Most importantly, we’re dedicating to working with your personal preferences and budget to give you the best window replacement options for your Stockton home.




It’s also important to be prepared before choosing windows replacements for your Stockton home. First, assess the windows you’re interested in replacing and write down their sizes and locations. Measure the level of sunlight each window receives - it’ll help us determine the best energy efficient options to save on your electric bill. If your windows have old vinyl casing or single paned glass, see if they have signs of rot or air leaks. Consider if you’d like to use dual or triple pane glass, single or double hung windows, and make a list of questions for our team. We know the process of window replacement can be frustrating, and our experts are the best at what they do - just check out our Yelp reviews!
