Zen Windows is Improving the Window Replacement Experience
Replacing your windows is something that most homeowners do only once or twice in a lifetime. That makes it easy for window companies in Alexandria to get away with bloated quotes, high-pressure sales tactics, and vague answers. We built our model to be different.
Window Installation That Works Around Your Life
One of the most common questions we hear is: “How can you quote without seeing my windows in person?” The answer is simpler than you might think. With a few photos and basic measurements, we can assess your needs and provide a reliable, customized quote.
Whether you’re replacing a few windows or every single one in your home, the steps are easy:
- You send us clear photos and measurements.
- We review your needs and provide a detailed, no-obligation quote.
- If you choose to move forward, we will coordinate everything to fit your schedule.
- Once your windows arrive, installation is scheduled and completed efficiently.

Throughout the process, you’ll know exactly what’s happening. Our communication is straightforward, our timelines are realistic, and we keep you updated along the way. We work with seasoned professionals who understand the importance of craftsmanship and respect for your home, so the work is always clean, on time, and done right.
What Alexandria-Area Homeowners Say About Zen Windows
“Scott, James, and their team at Zen Windows did an outstanding job. The crew was in by 8:30am and out by 6pm. Done and dusted. Less than 24 hours after the install I can feel an immediate overall temperature change inside my home for the better. This team is very easy to work with, there isn’t any dog-and-pony show sales pitch, and the investment is very affordable.”
— Doug K.
“We had Zen windows replace our entire entryway. Door and side window. They were great. Knowledge, helpful in making suggestions and providing options. And prompt with a very good price. The workmen were courteous and very meticulous to get everything just right. Our new entryway looks even better that we had imagined it would. Highly recommend them!”
— Lee B.
We love helping local homeowners make confident choices. And we’ll be here after the install if you need anything down the line.

Energy-Efficient Windows That Save You Money
Energy Star Certified Performance
We’re strong advocates of energy-efficient windows for their superior performance and long-term savings for homeowners. All our products are Energy Star Certified, which means they’re designed to limit heat transfer between the inside and outside of your home. This is particularly important for Alexandria homes thanks to our hot, humid summers and chilly winters.
Many of our Alexandria clients are in neighborhoods where homes are 15-25 years old and starting to show signs of wear. If your current windows are more than 15 years old, there’s a good chance that they are underperforming, and you’re paying for it with every utility bill.
Vinyl Windows Built for Efficiency and Durability
Of all materials, vinyl windows offer the best bang for your buck: they’re affordable, have good insulation, are very low maintenance, and they won’t warp, chip, or peel.
Vinyl windows are also highly versatile when it comes to style. Our windows come in a wide range of colors and can even match the appearance of wood for a classic look without all the upkeep.
Shapes and Styles to Fit Every Home
Good windows should look great while providing full functionality and comfort. That’s why Alexandria homeowners consistently choose these window styles:
- Double-hung windows for their versatility and traditional appearance.
- Sliding windows for maximizing view and airflow with minimal effort.
- Casement windows for a sleek, modern finish and powerful ventilation.
Have something else in mind? We work with a wide range of window shapes, sizes, and finishes to complement your home’s architecture and unique style.
