About us

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.

AVOID Window Nation at all costs. We have a bay window that needs to be replaced. I requested a quote online and “Briana” from Window Nation called me. I answered all of her questions multiple times including whether I (57F) was the sole owner of my home. I am the sole owner, which seemed to be something so odd that she kept asking questions about other people in the house. She requested the full name of my husband and anyone else that would be in the home for the consultation so (according to her) that they would not be “ambushed” when they came to give us a quote. I have never been so interrogated or insulted by a company in my life. Aside from having a sexist list of intake questions (apparently a woman cannot be a sole owner of a house), stating that their representative would be “ambushed” at my home was beyond anything I could tolerate. DO NOT USE WINDOW NATION.

We had a very positive experience with Window Nation throughout the process of replacing our windows. All employees we interacted with were very knowledgeable, responsive, and professional. They were focused on meeting our needs and doing a good job. We are very satisfied with the install of our windows, and the new windows are great. Window Nation exceeded our expectations with the replacement of our windows.

From the minute Danny began telling me about the windows to the morning after when I woke to a quiet and warm house, I was pleased with the process and the windows. This company knows what customer service and excellence is and does it right. The first 80 degree day I was anxious to go upstairs to see how the new windows did and I was so pleased that it was actually a pleasant temperature with no extra AC unit needed. Thanks for everything!

With our any doubt I am absolutely sure that having Window Nation replace my windows was the best decision. They had great communication before during and after the job, but most importantly that work done was on schedule and exceeded my expectations. The crew showed up on time and methodically and professionally moved from widow to widow and replaced all 14 windows in my home efficiently and on schedule. When project was done all my personal final inspection punch list items were fixed on the spot with no hesitation from the crew. What a great experience and the best part is my home is now more efficient and looking forward to seeing energy savings in my utility bills.

In August 2022, Jack Karau, came to our house to tell us about Window Nation windows. He showed us how they tilted in, how the screens could repair themselves, and how the company paid their installers through the pandemic even when there were no jobs. We were sold! The windows arrived in October and they were manufactured and installed by Vytex, not Window Nation. They were covered with a black tar substance and so many fingers prints that it took my husband two days to clean them using a credit card. Not to mention, 3 screens were ripped, a lock was missing, the corners of the bottom windows were not finished properly in the factory (they were ripped), and our yard was covered with insulation, cording, and pieces of broken windows. I called Window Nation and Jack to voice my concerns only to get a run around; no one was ever available to take my calls, I left voice mails, and I never received a call back. Vytex was a much better company to work with. I do not know how Window Nation is able to show commercials where they act like they make and install windows…how is this legal? Jack told us how Window Nation supported teachers and the military, what a joke! I have never felt so disrespected! Buyer beware! My neighbor went with Windows on Washington and I regret my decision. I wish I had my crappy 30 year old windows back. This experience has been horrible!

I had 21 windows removed and replaced in June 2022. The Lorton Va team, salesman Daniel Simon, Sales Manager Warren Kelly, and the Office lead Bevin Campbell have at a minimum been liars and swindled me out of $300-$700. I had been lied to both by phone and via email, repeatedly and at this point, I am paying for services that were never delivered. The salesman, Daniel Simon concluded that the install team would need to utilize scaffolding which we were told would cost $700, in order to install a 2nd-floor window on the contract, which is not itemized and is a huge red flag, there was no price for this scaffolding. The installers NEVER used scaffolding to install the window, and I have pictures proving they did not. I provided these pictures to Window Nation and I have still paid for the scaffolding. I tried for months to call every number on my contract, and I was told by Daniel Simon, Warren Kelly, and Bevin Campbell that the charges would be removed. This was a lie.

After months of waiting for my new windows. I came home to find the wrong windows were installed. I immediately called and informed them about the issue and they never reached back out or came out to assess the problem. Im stuck with windows that I didn’t order.

The technicians arrived earlier than we expected. They informed us of everything they would be doing and the approximate time it would take. They were very thorough, did an amazing job, cleaned up after themselves. We had no issues at all with the entire process. The front main window was considered 6 windows in all, 3 small one on top, one large bay type window and 2 windows on either side that opened. Total windows replaced was 9.

Window Nation was in contact with me throughout the process. My windows arrived earlier and I was able to get a quicker install. The installers were very professional and did a great job in completing the project in one day. They answered all my questions and were patient with me learning to operate the new windows.

installation was satisfactory. but the wrong bay window was installed. due to the incompetence of our salesman. we specifically talked at length to have the bay window without white cross planes. signed off on the contract thinking he did his job, stupid us. now windows wants to charge us 400.00 to replace the corrected window. that's BS!!!!! we paid 18,000.00 for windows and did not get what we paid for. we are giving a bad review on social media and will NEVER recommend window nation to anyone. if windows wants to correct the problem. we will be more than happy to change our review on social media.hamad at windows said in a voice mail that windows wants us to be very satisfied with the company.too bad!!

Poorly. I had a big job; the replacement of 32 windows on my home. I thought by hiring a big company, Window Nation would do it well. I was wrong. This simple job which should have taken one day, took 9 months and two repeat visits. Window Nation measured the windows wrong on 5 different occasions. Window Nation has poor internal communication and poor customer service. I would not recommend Window Nation to anyone. Window Nation came to my house on five occasions: 1. The sales person signing the agreement in December 23, 2020, 2. Installation #1 in March 20, 2021, 3. a supervisor who measured an assured me it would not happen again in March 23, 2021, 4. Installation #2 in June 2, 2021, and 5. Installation #3 on September 7, 2021. The original installation date for the windows was March 20, 2021, but ended in September 7, 2021, more than 5 months after the initial installation and over 9 months after the signing the contract. We have several issues with Window Nation. First, we have more than patient with all the setbacks Window Nation presented to us. At nearly every instance, Window Nation was careless about the promised work. To be clear, I am disappointed in the management and supervisors, not the installers. Every single installation had a quality control problem with the windows. Unless I specified the issues clearly, those issues would still be unresolved. Second, your customer service really was quite poor. We have dealt with two representatives from customer service. I had many calls unanswered and nearly as many emails. Every time there was an installation, my wife and I had to take annual leave, change schedules, change our routine, move furniture, and make accommodations for Window Nation workers. It was a big deal every time it happened and a major inconvenience. During the March 20, 2021 installation, three issues emerged. First, 5 of the 6 trapezoid windows were measured wrong and would not fit. 3 of the 5 were mirror images of the one side. That would mean the inside part of the e-glass would be outside. Not only that, none of the five would fit. This is after two different measurements by Window Nation personnel. The window at the entrance was clear, not frosted as per the contract. One of the interior windows in the living room was missing the trim. The team supervisor made a report and took photos. Despite all this, we honored our end of the contract. We displayed the sign placed in our yard stating we were “another happy customer” for 30 days as per the contract. The next Tuesday, March 23, 2021, a man who identified himself as one the original Window Nation employees came to measure the windows. He measured the trapezoid windows repeatedly and took photos. He said he would get the measurements right and he had been measuring windows since the beginning of the company. He assured us the frost window would be a simple matter of popping out one for the right one. He also said the trim would take all of a minute to fix. Not only that, he said the small windows could probably be done by someone on their way to another job, since it was so minor. During the months of April and May, we waited. I sent messages outlining what was missing. I expected a wait of 2 months. The March 23, 2021, man said the production was starting up again and the wait time would be less. On June 1, 2021, was the scheduled installation date. At first the crew was cancelled. Then, a crew was found, and finally a crew was on its way. Then the truck had a flat. They rescheduled for June 2. The June 2, 2021, installation was also mismanaged. 1 of the 5 trapezoid windows did not fit. There was no frosted window replacement. There was no interior trim for the living room window. This is all with numerous measurements at the other installation, and a specific window install. 3 of the 5 windows were measured wrong as well, as the workers had to take out the framing 2x4s and replace one with a 1x4. Nevertheless, those three windows were successfully installed. Again, the team supervisor took photos and made a report. During the months of July and August, I repeated the missing items from the contract. I was updated sporadically and by different people from Window Nation. Some of the updates were conflicting or in error. At the September 7, 2021, installation was nearly the same story. The windows were now here and installed. However, the trim on the interior living room window was not. I had mentioned the trim for the window for the previous 9 months. After nearly 4 hours when I pointed it out, the trim arrived. The job was complete, after numerous communications and missteps on the part of Window Nation. I strongly not recommend nor hire Window Nation again.

Window Nation agreed to do 17 windows and we signed a contract for the work to be done. Within the contract that Window Nation agreed to was a change order that Window Nation would remove and replace all window treatments and blinds on the windows that were replaced. They agreed to do that. Well upon completion of the window installation, the Window Nation installation crew told me they don't do that. I showed them the agreed upon contract and they still would not do it. In addition to that, the crew leader let me know at the end of the installation that the blinds that were previously on the windows might not fit anymore. I was amazed that this important piece of information was not brought to my attention before then. So I was left with putting bed sheets over the windows until I could get the blinds reinstalled. I have placed several calls to the Window Nation Customer Service requesting someone call me back to discuss options but nobody has returned my calls. Seems they do not want to talk to me about this. If you do business with Window Nation beware they might not do what they agreed upon within the contract.

They kept us informed when our windows would come in and once in stock they came to install quickly. The day of instillation the crew was on time, great to work with and did an amazing job making it look great inside & out. They were done with the job in only a few short hours, cleaned everything up inside and out and explained how to use & clean the new windows.

From start to finish, it was perfection. The salesperson that came to the house was wonderful to work with. I am older and have been pushed into "great deals" many times in my life, so, I prepare myself to have to defend my opinion and money - ha ha... It wasn't needed at all. There is NO high pressure. There is NO "sign these papers today or you lose your special price" - NONE of that nonsense that I have always been used to, especially as a woman. The installation was actually fun. The crew that was here were some of the happiest guys ever. They definitely KNEW everything about their job, worked quickly and accurately. The yard was not left a mess. The crew leader came in after the job was completed and walked through all the rooms and tested the windows with me, explaining how they work, lock etc. I had what I thought was a small issue after installation. The company sent a man out within a couple days and all was well. I highly recommend Window Nation. We will be using them again in the future when it is time to replace some of the other windows. We only replaced the windows across the front of the house where the sun shines in so strongly in the afternoon. They have definitely made a difference in loss of our air conditioning in summer and loss of heat in the winter. You could feel a breeze when we sat next to a couple of our old windows. You won't be sorry you chose Window Nation!
