First things first: Do you need a replacement window?


Moisture issues

If you've seen water between glass panes, leaking, water stains, or evidence of wood rot - those are signs that excess moisture is accumulating where you can't see it. This can lead to damage, including mold, mildew, and warping. While some condensation is normal, an excess of moisture often points to a problem.

Energy efficiency

If you need to wrap up in a blanket to sit by your windows, it may be time to switch to more energy-efficient windows.

Not working properly

Older windows have a tendency to break down and often refuse to open or have a hard time closing. Save yourself the headaches and consider new options.


Insert and Full-Frame Replacements

Depending on the age and style of your home, Infinity offers two window replacement methods. Your local Infinity partner will help you determine the best solution for your home, including addressing any concerns about water or structural damage. Both methods are designed for maximum efficiency and minimal disruption to your home.
