Working Together
We are not commission based so it’s our job to help you find the best solution rather than the most expensive. Eliminating the pushy in-home salesman keeps costs down and quality up. Our window experts are here to help with solutions.
Why Choose Us?
As one of the larger companies in the country every manufacturer wants us to carry their products. We evaluate the options to make sure we’re always offering the best value in the market for quality results today and every day.
Trusted Professionals
Projects are measured and installed by the manufacturer’s installation service to ensure quality results. It’s like taking your car to the dealer for service vs the corner mechanic. Our prices are more competitive because of our unique business model.
Let’s start your next project
The first step is to request pricing online. We’ll ask for basic info about your project and we’ll send you itemized pricing and product info by email.
This is a starting point. From there we can answer any questions and make unlimited revisions until we have the order exactly the way you want it.
You don’t need to be a window expert and you don’t need to measure anything. Welcome to the future of replacement windows.
Who are we?
Window Universe was founded by Dan Schweihs and Bianca Medrano in 2008 in Alexandria, VA. The DC area and Northern Virginia have been our home since the beginning. Since then we’ve helped thousands of customers replace their windows and doors while avoiding many of the pitfalls of the replacement window industry.
We separate ourselves from the competition by offering clear, simple, itemized prices with quotes by email and professional installation. We sell windows the way we’d like to buy windows.
Dan also runs TheWindowDog.com sharing insider info about the window business. This has since become one of the most popular websites about windows and doors on the internet. Learn more about our history.

Efficient windows for our local climate
We’ll send the following info when you request our price list by email:
- Itemized cost of popular efficiency packages
- Efficiency ratings for several logical packages
We have replacement window options that meet the Energy Star “Most Efficient”. Many companies offer products that don’t actually make sense in this climate. Our suggestions will be based in real logic.
Remember, we make this whole process just as easy as possible. We’ll offer a range of options that make sense for the climate here in the Washington DC area. We show you the cost and the difference in efficiency level so you can make the best choice.
The power of color is undeniable
Wide range of products
Here in DC we offer products that will perform well over the long term. Different projects need different products, but all of our customers are looking for quality and durability and a good value.
In this area we see a lot of double hung windows, picture windows, horizontal sliding windows and casement windows. We also offer bays and bows, garden windows and many door styles.
There are some companies that can only offer a few product options. Interestingly this is often caused by a lack of training for their salespeople. They keep their offering simple to avoid confusing their own people. Our window experts have an average of over 10 years of experience in the field. That’s one reason we can offer a wider range of choices than the typical in-home sales type of company.
Brands available in the DC Metro:
Northern Virginia showroom is available
The professional installation department is based out of the warehouse and showroom in Lorton, VA. If you’d like to see a sample window in person that is an option.
Lately more people are comfortable ordering online, but you can check out a display window in person if you’d like.
Note that every option is NOT on display so it’s a smart strategy to get a quote by email by filling out the form at the bottom of the page first. Then we can confirm showroom availability.
