“I can’t say enough GREAT things about Window Nation. We needed all new windows for a long time. There are so many companies to pick from but we chose Window Nation because their commercials stood out in my mind. We filled out their online contact form and within a couple of minutes we received a call to step up an appointment for a salesperson to come to our house. The salesperson was at our house a few days later and he was FANTASTIC!! He was very personable, helpful, and we learned so much from him. Once the windows were purchased, the process moved quickly. Window Nations put all of the documentation together for us to send to our HOA. After HOA approval, they quickly had someone come to our house to complete the window measurements. The man that completed the measurements was very meticulous and right on point. Next thing you know we were called by Window Nation to set up a date for installation. The installers were right on time (literally to the minute.) They were wonderful, super friendly, and fast. They too were meticulous about the work. They cleaned up once completed. They had us walk through and make sure all of the windows looked good, functioned, and answered any questions that we had. Since our windows were installed there is a huge difference in the temperature of our house and they look AMAZING! Thank you Window Nation.”

“The initial interview was good. Thinking back I wonder how experienced he was by the way he answered some of our questions. When we questioned the colors he more or less chose the color. I had to question that a number of times. Finally he sent me a sample of the colors. Evidently he didn’t make a note that the FedEx overnight fee was to be deducted from the final payment. Now that the windows have been installed we are happy so far.”

“The job was incomplete. There is a laundry list of issues. We watched the installer pull the door knob off and not fix it. The doors are dented. The frame isn’t completely screwed in. The caulk job looks like trash. There’s spots where they didn’t caulk at all.”

“I like the windows a lot but I do not like anything else about the sales process. Sales rep told me he only earns commission if I decided on the spot at the estimate appointment. We like to evaluate purchase decisions worth a couple thousand dollars and don't appreciate feeling like I'm stealing someone's livelihood by taking our time. Also do not like that both homeowners need to be present for a sales presentation. I make all the purchase decisions for our household - requiring my husband to be present is antiquated and disrespectful.”

“If they nailed the entire job, it would be a 5-star rating, but I have an outstanding item that it is not installed correctly. It has almost been two weeks to identify the issue, and they can't fix it right away. In the meantime, it doesn't close properly.”

“Window Nation was on time, and the workers were very professional. They left my property in the same condition they found it. They cleaned up after themselves. I was very pleased with the service.”

“Workers showed up without sills and Told me they did not need to be replaced because my existing sills were still in good shape, I asked to speak with someone about the bill due to the sills being included on the purchase agreement. I never received a call and the workers continued to work, I ended up contacting the call center due to the workers continuing to install the windows on top of the existing sills. I then received a call back and the workers were advised to run to Home Depot to pick up materials that they did not show up with. I was told there was a computer glitch and the sills were not on the work order. After reviewing my agreement the sills were clearly stated on the order. The windows has to be taken back out so the sills could be installed. After only replacing 5 of the 9 sills the worker told me he did not have any more sills and was going to put the old sills back on, I advised that is not what I paid for, he then walked away without saying a word and left, I’m assuming he ran back to Home Depot. I was told the job would take 2-3 hours from the salesmen. The workers were on site 10 hours Im cold temperature with my home reaching 48 inside by 6pm. Needless to say it took my home a long time to get back up to temperature when they left.”
