Before you consider making updates to your Manteca home or office and making a decision for your windows replacement, Green Technology Windows and Doors suggests you take the time to do some preparation before your installation. Measure the windows you’re interested in replacing, so we can price for different sizes. Check these windows to determine how much sunlight they bring in during the day, and if they’re prone to letting in a lot of heat. If your windows are older with single-pane glass and worn vinyl casing, see if they have signs of rot or leaked air. These elements are key to deciding on the best vinyl retrofit installation options for your window replacement for your Manteca home.
