At Window Nation, we know replacement windows. We’re third-generation window replacement experts who have been lucky to provide homeowners replacement windows, siding, and doors for over fifteen years. We opened our first showroom in Maryland in 2006, quickly growing to serve homeowners in cities across the country – and we’re not stopping there. We’re grateful for every homeowner who has trusted us to upgrade their most important asset: their home. We’ve learned a lot about home improvement over the years, but the most important thing we learned isn’t about window replacement. We learned the home improvement industry isn’t about offering the best windows, siding and doors; it’s about the relationships we build with our customers.
"Love our new Grand View Windows from Window Nation 17 Windows and 1 Sliding Glass Door We did quite a bit of research, explored a lot of companies and choose Window Nation for our project. And we are happy we did. The whole process from presentation to installation was easy and efficient. Reza arrived at our house on time for the presentation. He inspected and measured our windows and then launched into the presentation. Reza is knowledgeable about the Window Nation offering as well as the products offered by his competitors. As mentioned, I did some research and had an idea of the features that we wanted and what we should pay. Reza presented the Window Nation Grand View line, which meets our feature requirements, and after a bit of back-and-forth negotiation we settled on a price that was within our range and fair to us both. After signing, Reza described the next steps and set expectations. Overall, the presentation took only about an hour and was relatively painless, with no high-pressure tactics. Several days later, Mike came by to inspect our windows and confirm measurements for the build specifications. This took only about a half-hour. Mike answered some questions about the installation process and said that the windows and door could take up to 6 weeks to build. Imagine our surprise when we received a call a week later to schedule our installation. On installation day, the three-man team arrived on time. They introduced themselves and the team lead, Ted, described the process and then they got right to work. They tarped the paths to all the windows to protect the floors. They were very careful and respectful of our house. The entire team was friendly and polite and experienced and highly skilled. You could tell that they’d done this a time or two. The outside trim work is fantastic and the inside finish work is great. All 17 windows and the sliding door were installed in a single day. Ted went over the operation of the windows and door. The windows and door look and function great. We couldn’t be happier. If you are considering a window or door replacement project, we strongly recommend that you engage Window Nation. They will treat you right."

"Once the special-order siding was ready for delivery, Mike scheduled the installation. James was assigned as our Project Manager/Mechanic, and he and his crew spent four full days at our home. (Gutter installation took an additional day). James, who has worked for Century Siding for 20+ years, explained everything in detail, answered all our questions and offered suggestions. He and his highly-skilled crew were detailed, thorough, efficient, and conscientious about clean-up. James expertly hand-crafted and installed the PVC trim, increasing the beauty of the new siding and soffits. We were delighted with Century Siding’s professionalism, ethics and service from the initial contact through completion, and give them a five star rating. Thanks Mr. Kim and Mike for consulting/scheduling, and James and his team for exceptional results which exceeded our expectations. Our house looks 30 years younger!"

Locally owned and operated. We are here to turn your project idea into reality. Additional phone number - (703) 830-6103.
"It went exceptionally well from beginning to end. My contact with the company was through Chris and as I told him when the job was completed, it was the BEST experience I ever had with a contractor - and I have had more than a few contractors over the years. I received quotes from 2 contractors to install the window, and while Clifton charged more, I got more. Chris put me at ease from the very beginning about the install and possible water problems; it was obvious that this wasn't Chris' first install. He spent time with me going over all my questions and explaining in detail the project and how it would be done. He recommended some additional work involving drainage and landscaping and spelled out the pros and cons for each. He covered everything and when I got his proposal, it was all spelled out with options noted and additional costs. I got to pick what additions I wanted and how it would impact the cost of the contract. His crew showed up on time each day and worked hard from beginning to end. They kept me informed each step of the way and took care to keep the work area clean and safe. I was super impressed with their attitudes and friendliness. And most of all, I was super impressed with the professionalism of their work; the project totally exceeded my expectations. I am so glad that I opted for the more expensive contract in this case; it turned out so well for me. I wouldn't hesitate for one minute to have these folks do work for me again - they are really super!"

"Had windows and doors installed by this company. The window installation went great. The bad news is that they do not seem competent at installing door hardware. My door has not latched properly since they made some unwanted modifications to the hardware (it worked perfectly before they started modifying it).have had them out three separate times to fix the issue they caused with the door latch and lock. Every “fix” they do seems to make the problem worse. I would steer clear of this company for door installations."

Making an existing window bigger always requires some construction, but the extent varies by project. Vertical expansions involve less structural work because they often don't affect load-bearing elements. Even so, any enlargement requires removing siding or drywall, cutting framing members, and installing appropriate support. Non-load-bearing walls allow for simpler modifications, while load-bearing walls require proper headers and structural support. A consultation with a structural engineer is advisable before beginning any window enlargement project.
Building permits are required for window enlargement projects in most municipalities. Since enlarging windows involves structural modifications to your home's exterior walls, local building departments need to review and approve the plans. Permit costs range from $100 to $300, though projects requiring significant structural changes may incur permit fees of $500 or more. Additionally, homes in historic districts or those governed by HOAs may need special approvals. Always check local requirements before beginning work.
An average window enlargement project takes between five hours and three days to complete. Simple projects with minimal structural changes might be finished in five to ten hours, while more complex enlargements requiring significant structural modifications could take up to three days. Factors affecting the timeline include the window's location, wall construction, weather conditions, and the need for specialized materials. The process involves demolition, framing, window installation, and interior/exterior finishing work.
