Slider Windows

One of the more classic window designs, slider windows glide open along a reinforced rail, letting you bring in as much or as little ventilation as you prefer. Given their ease of operation and timeless look, slider windows are among the most popular window choices for homes across the Mid-Atlantic.

Just because these windows are common, however, doesn’t mean you can trust just anyone to install them. For a weathertight seal and durability that lasts, you should work with only qualified and experienced window professionals—like ours at Wheaton Door & Window Company! A leading provider of slider windows since 1945, we have a host of industry accolades to speak to the quality of our replacement windows as well as our service:

  • A+ Rating and Accreditation from the BBB
  • Voted “Most Reliable” by Washingtonian Magazine
  • Platinum Dealer of OKNA and Starmark Windows
