Window Nation - Maryland & DC Reviews 

The installer that came were professional on time cleaned up everything very professional

Did not receive good customer service attitude from technician who came out to check my complaint about cold air from den and bathroom windows.

From my sales professional Logan L. who was very knowledgeable and professional to Sheila with HOA to the installation team who were timely and respectful of property I give window nation 10/10. Cost beats the competition without compromising on quality.

Our slider door handle is not ergonomically correct. We did not realize there could be an issue with a sliding door handle. This was our 2nd job - we had 19 windows installed. On the slider door install date, we immediately alerted installers there was a problem and they reported. A technician came to look at it, took pictures and agreed there was a problem. I was told a part was being ordered, which we assumed would be a longer lock flip switch. Same technician returned without a part and we were told he would escalate. Months later and we are using a dish towel to pull our slider door open.

Never using them again. Poor customer service and poor workmanship.

The crew was great and when they hit an issue was able to pivot and come back the next day to finish for a beautiful result.

Excellent customer service.

Door is beautiful! The installers did not guide me through the keys functioning or how to set up combination lick. The bottom lock is non functioning..Waiting for word from service department! This could had been avoided if workers would have checked that keys and locks were working before they took off!

Window Nation is an outstanding company. While the pricing may be higher than some alternatives, you truly get what you pay for, and they offer helpful programs to accommodate different payment needs. Logan was exceptional—he promptly answered all of my calls and addressed every concern. The installation team was equally impressive; they did a great job and made sure everything was cleaned up afterward. Overall, a great experience from start to finish.

The experience was good. The Installers were here within the arrival time given. They were efficient, prepared with supplies to protect my property (carpet). They were very knowledgeable when asked questions. They were polite/professional installers. There were 2 instead of 3 like presented to me initially, but they worked like 3 people were here. Everything went well except for when i went to all the rooms and discovered that after the job was "completed" first, my window blinds were not rehung like I was told the window coverings would be, and second, my wallpaper in one of my bedrooms got ripped on the wall then third, one of the screens did not come and I was told it would be scheduled with you to get it delivered and installed. I was very pleased with the clean up that was done. The guys were very helpful in cutting all the lights off and cleaning up after the drop clothes were pulled up. I was sympathetic to them because it was so cold out but they endured and did what had to be done. I'm very satisfied with Nation Window's installers and the product but dissapointed that my blinds were not rehung and my wallpaper got ripped. 😕 Overall, thank you Nation Windows for a good job! (Bring my screen please.)

Installers were pleasant and professional. The finished product was better than I expected. Installers replaced 5 windows 4 on the second floor and 1 on the first floor. There is no cold air leakage around the inside of the windows, and the outside trim looks great.

Well, I'm looking forward to Window Nation resolving my new leaky window installation issues. If they can resolve these issues, most likely, I'll be happy to provide a better response than what I'm providing now in the future.

Everything turns out great. I did want full windows screens and not halfway. Waiting for a appointment to schedule for the screens.

The only problem I had with windows nation is that I could never get a call back in accepting the gift card for my second project. I just kelp getting transferred to different apartments and no results.

Salesman understood and met our needs, windows were produced and installed timely. The install crew was diligent in working to get the job complete, were polite and respectful while in our home and company. Very satisfied with craftsmanship of install on the outside of the home as well as inside. They look and feel great!

What I do not like: It took almost a month to respond to my request and another 3 weeks to get someone to address it. That gets 3 stars
What I do like: The gentleman who finally made it over here on Monday 12/1/2025 was early, efficient and had the disconnected sliding glass reinstalled in a matter of minutes. That gets 5 stars.

The installation appointment we thought was supposed to take 2 days for all of the windows and door to be installed but the crew of guy had everything finished in less then 8 hours.

The job moved along quickly and smoothly. The 2 men were very good at their job and courteous of my property. Would highly recommend your company.

nice workers and they clean up very good when they were finished. they also clean my window seal that damage by another worker last year.
