How We Chose the Top Window Replacement Companies

To help you find the best window replacement company, our reviews team researched numerous window repair and replacement providers, analyzing their services, reading through their guarantees and warranties and observing their customer service options, among other factors:

  • Services: We awarded more points to companies that provide multiple window repair and replacement services, including broken glass and double-pane window repair, window component and mechanism repair, wooden window repair, energy-efficient window solutions, glass protectant services and specialty glass services for mirrors, doors, tabletops and other glass household items.
  • Reputation: Some window repair companies may not provide great services or live up to their guarantees. We rated companies based on their Better Business Bureau (BBB) ratings and customer review scores. We awarded more points to companies with higher BBB ratings and positive customer reviews.
  • Warranties and guarantees: We scored providers based on whether or not they provide guarantees with their services, as this benefit ensures a repair or replacement is properly completed. We also considered whether or not a company offers a warranty of five years or more, as window and glass repairs may not show issues from the repair until years after.

Additionally, companies that supply same-day or emergency repair services received more points.

Window Replacement in Kansas City FAQ

How often should windows be replaced in Kansas City?

The average lifespan of a window is between 20 and 25 years. However, exposure to extreme weather, bright sunlight and moisture can cause windows and their mechanical components to leak or break. If you have cracked windows, fogged glass, rotting frames, stuck sashes, drafty rooms or rising energy bills, it might be time to get your windows replaced.

What’s the best time of year to replace my windows?

The spring or early summer is typically the best time to replace your windows. The temperature won’t be too warm, and you won’t have to deal with as many insects as you would in the peak of summer. 

However, Kansas City gets the most rainfall in May and June, so you may want to replace your windows in September or October when the weather begins to cool off. If you need an emergency repair, don’t wait for a particular season—try to schedule a window replacement as soon as possible.

How should I prepare my home for window replacement?

Whether you’re replacing one window or all of them, there are a few things you can do to prepare for professional window installation. Clear the area of anything breakable or delicate, and take down any blinds, curtains and window treatments. Trim your landscaping and cover or move your furniture as appropriate. Make sure that the technicians have easy access to an electrical outlet, and do your best to keep children and pets out of the way.

Good installation crews will clean up after themselves, but you can make things easier by clearing the space before they get to your home.
