Old, drafty windows are one of the biggest sources of air leaks and energy loss in homes. Replacing your windows can bolster your home’s energy efficiency—increasing your comfort and saving you money (it doesn’t hurt that new windows also look great!). Stop repairing old windows in an attempt to squeeze another few years out of them—it does more harm than good. At a certain point, window replacement is a much better option!

How often should you replace windows?
Residential windows generally last between 15 and 30 years depending on well taken care of they are. Generally, if you notice your home wasting more and more energy on heating and cooling costs (when your HVAC is in good shape), your windows feel drafty, or you notice signs of damage, it’s time to replace.
How long should it take to replace a window?
For residential window replacement, your entire project should take a single day. You can expect it to take about 30 minutes for our replacement window installers to switch out each window, so multiply that by how many windows you have and you should get a rough estimate.
What replacement windows are best?
The best replacement windows for your home depend on many factors, including your budget, your home style, and your energy efficiency goals. At Quality Window & Door, we’re big fans of Weather Shield and Infinity by Marvin brands of windows in various materials.
How much does home window replacement cost?
A home window replacement project could cost anywhere from $5,000 to $20,000 depending on the materials, the number of windows, and whether the project involves complete tear-outs or just sash or insert replacement. You can learn more about the cost of window replacement in our free guide!
