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.

Exterior Medics recently accomplished a face lift of our front porch and carport. We had three windows replaced and removed shutters and replaced vinyl siding with James Hardie board and batten panels. We also installed vinyl soffit coverage to entire carport and porch ceilings. Finally, we blocked out our 7 existing wooden columns around porch and carport with PVC. Everything was painted and it looks fantastic! We were pleased with Ben, our sales representative who guided us through our concept to get to our vision of the project locked in. Eric Holmes, the project manager provided excellent communication through the scheduling and during the actual construction phase by discussing each detail of the renovation to assure he and the crew were clear on our expectations of what the finished product should look like. He visited with us and the crew on site on the morning before the work got started and was there to rectify a problem with the supplies that were delivered. And called on the second day to check on the progress and after completion to check on our satisfaction. The 3 man crew led by “Chapes” was phenomenal. They were very skilled and made suggestions as the work progressed to make the final outcome even better than we hoped. I appreciated their experience and expertise very much.

We worked with Ron Rodriguez at Exterior Medics and had an amazing experience. Ron is knowledgeable, patient and creative and helped us chose the best windows and garage door for our home. Our house has been transformed thanks to Ron’s creative touch. We have been so happy that we have just entrusted him with a new important project for our house. Ron, we are very lucky to have found you and would highly recommend your services to anyone looking to remodel their windows. Thank you!

We found Exterior Medics to be the best choice among 5 vendors from whom we obtained estimates. Not only did they offer the best prices and quality (ProVia products) but with outstanding personnel. What made the choice easy was the company rep, Ron Rodriguez, who was straight forward, honest and just plain friendly the entire time he spoke with us from the first meeting and every time since. After now three orders with Ext Medics since last summer, we've been able to recondition the windows of our 1942 Cape Cod to realize a more energy efficient, beautiful and livable space. Lead times were an issue for our first order, but during installation, the ground team did an exceptional job to safely and efficiently switch out the old to the new - with minimal impact on our lives and the house. Despite huge customer demand which at times made managing the install difficult, the Ext Medics team always came through to provide the right level of attention and service. Highly recommended for your next window upgrade!

I am employed with an HOA Management company, and we work very closely with Exterior Medics for a number of our communities' needs. Melanie has excellent customer service skills, she is very professional, and always quick to respond to emails or phone calls. I would definitely recommend this company if you care about quality service and workmanship!
