Sliding Window Repair and Installation in Greater Washington

Make a beautiful statement in any room of your home with a horizontal sliding window. Sliding windows, also referred to as sliders, are multi-faceted windows consisting of a master frame with one or more horizontal sashes. The available options and combinations of sizes, colors, finishes, textures, glass, wood species, shapes and designs are only limited by available interior space and your imagination.
Quick facts about sliding windows
  • Sliding windows are available as single or double sliding. Both are popular styles for contemporary and modern homes.
  • Single sliding windows open up on one side, while both sashes open in the double sliding window. Sliding windows open quickly and easily for fresh air ventilation.
  • These window replacements are very popular in kitchens and rooms with only one window, and sliding windows do not use any interior or exterior space to open.
Sliding window features and options
  • Classic wood frames provide a home with warmth and beauty.
  • Vinyl frames are virtually maintenance-free; do not rot, peel or need paint.
  • Energy-efficiency packages tailored to Northern Virginia and Southern Maryland climates.
  • Several glass options are available for privacy, energy efficiency, sound reduction, strength and UV protection.
  • All sliding windows are custom fit to project specifications.
  • Add a customized grid to accentuate any space, or choose no grille for optimal viewing space and light.
  • Sashes lift out for easy cleaning.
  • Sash-integrated opening/closing/locking mechanism for easy function.
  • Closed and locked sashes can not be removed from the exterior of the home.
  • Interlock meeting rail for security and energy efficiency.

I am continually impressed by the products, quality, and craftsmanship of Exterior Medics. This is our second project with this company and they DO NOT DISAPPOINT. Further, we have SUCH peace of mind knowing that our new roof (2016) as well as our new windows (2020) contain a 50-year warranty. This far surpasses their competitors' offers.

Zach [from Exterior Medics] showed up on time and was very knowledgeable. He was the most thorough contractor so far in terms of the time he spent inspecting the interior and exterior of the problem window to identify what was needed to repair the leak...Based on his professionalism and demonstrated knowledge, I will definitely consider hiring Exterior Medics for future work.

I live in a condo that had been plagued with a leaking terrace. [Exterior Medics] came in, took it to the studs, replaced two windows and a door, repaired the years of damage, relined and repainted and haven’t seen a drop of water since. Their crew was polite, respectful, responsive and showed up on time for each scheduled meeting.

Professional install and I love the look of my new door. Had to special order it since I wanted the glass tinted. It took some time to receive it but the project manager updated me at every step. Could not have gone better.
