The Best Replacement Windows for Your House in Lenexa, KS

Beautiful two-story home with lots of different window styles, including round-top, casement, and archedAfter more than 40 years in the exterior home remodeling business, replacing house windows has become second nature to us at Johnson County Siding & Window Co. But that doesn’t mean we’ll treat your upcoming window replacement project in Lenexa, Kansas, as anything but one of a kind! When you trust us to help you select new windows, you’ll have a variety of top brands to choose from, so you can get high-quality, custom windows that flatter your home while also boosting its energy efficiency. Here are two of the most popular types of house windows we install:


With slender frames crafted from ultra-strong fiberglass, the replacement windows available from the experts at Marvin® are lovely to behold and loaded with features that ensure their beauty is so much more than skin deep. With multi-pane glass, gas fills, and low-emissivity (low-E) coatings, our fiberglass windows offer exceptional energy efficiency in a climate like ours, where we experience extreme temperatures in the winter and summer. Moreover, fiberglass is much more resistant to shrinking and swelling than other window frame materials, and that dramatically reduces the potential for seal failure that could undermine your energy efficiency benefits.


We install ProVia® replacement windows with frames that are exquisitely crafted from premium SunShield® vinyl. Why does this matter? The high-quality vinyl in ProVia windows is fortified to improve impact resistance and resist discoloration and other damage from harsh sunlight. The vinyl frames from this award-winning manufacturer are also engineered to provide industry-leading thermal performance, and you’ll have many upgrades to choose from if you want to boost your new windows’ energy efficiency to the max.

No matter which windows you get from us, they will be flawlessly installed by certified technicians who follow the manufacturer’s specifications to the letter.
