The Stress-Free Way to Window Replacement

Our philosophy is that window replacement should be stress-free.

But more than that, you should be able to relax and enjoy the home renovation experience.

That’s why, instead of trying to pressure you into a sale, we’ll simply provide helpful information about our great replacement windows and installation services and then let you decide if we are the right Olathe window company for you. Our services will begin with a free in-home consultation during which we can discuss the features of any or all of the window brands you’re interested in and help you make the best choices for your home. Some of those choices will include:

Frame Material

Thanks to our lineup of replacement window options, we can outfit your home with gorgeous and exceptionally long-wearing fiberglass windows from Marvin, beautiful composite or enhanced-wood windows from Andersen, or exquisitely crafted vinyl windows from ProVia or Simonton. No matter which is right for your home, we’ll ensure that your selection meets your desires for energy efficiency and minimal maintenance requirements.

Color & Style

Whether you’re in the market for tried-and-true double-hung windows or you’d like to explore options for casement or sliding windows, we’re sure to have exactly what you’re looking for—and we’ll help you weigh the pros and cons of any window style if you’re not sure. Have you been eyeing the trendy black-frame windows at your neighbor’s home? We can help you consider whether replacing your windows with a different frame color is a good idea.


The window manufacturers we’ve partnered with offer plenty of options to customize the glass in your replacement windows, whether you want specialty patterned glass or a glass upgrade that will take your new windows’ energy efficiency to the max.
