“I was charged for a service that was not done and not turned out as not necessary. The installers told me they didn't need to move the binds, they were not in the their way and went on to install the sliding glass door. The Richard has refused to grant any credit for the money I paid for unnecessary and undone tasks that were added to the bill, such as, removing and installing the blinds. I tried calling Jeff Beck. That went to a support team and they said I will back from them in 2 days, explaining what credit I can expect. NOTHING! After replacing all the windows and patio door, I would expect a little more consideration from your company. It would be difficult to at this point of recommending Window Nation to a friend without telling them my experience.”

“The speed and professionalism. Love the windows”

Review by
08/22/2025

“I bought windows, and a week before the installation, my wife fell and broke her hip, so I couldn't have the installation done in May as planned. Everyone, specifically the sales manager, was understanding. They talked to me and agreed to hold the windows until September. They went out of their way to help me with my situation. When my wife came home from the hospital, she was using a walker, so she was nervous about having many people in the house for the installation. John, the manager, sat with my wife for hours to make her comfortable. The workers were professional, nice, and well-trained. They knew their job and worked together as a team. Everything went well, and they cleaned everything afterward. The house was cleaner when they left than when they arrived. I have no complaints at all.”

“On the original installation date the measurement was wrong on the big sliding window, so had to wait for a 2nd install date, The install guys seemed to be in a hurry & rushed through the job & I found one of the screens damaged in which they replaced on site in a rush and when they left I discovered the replacement screen was darker then the other screen and the windows were dirty and smeared on both sides. The double hung bottom window moves around & leaves a gap between the window & frame in which there is a service call repair scheduled a month out.”

“The communication from the sales team to us is very poor. The installation crew was good and cleaned up after themselves, and they did a good job. The windows look nice, but the actual process was horrible. The sales department lacked communication and follow-through when communicating about the contract itself. The installation team did a tremendous job and even did amazing work when cleaning up after themselves, and they were efficient with the follow-up actions that needed to occur. There was a window installed that was not the correct window, and they still haven't solved that issue.”

“It was great that the process in the house was done in one day with a great variety of resources teamed together to finish the task in one day. Even though it started to rain with a potential of severe weather the team stayed to get all the inside windows down. There was a window bay wrap that was not completed and I thought it was due to weather. Still waiting on an response from the install manager when this can be completed??”
