The two-man staff did our 5 windows in one morning with no mess left and a short though comprehensive and clear out-briefing. The manner of the senior partner was professional yet friendly.

5 new windows - Window Nation is an excellent company!
The window installers were true professionals! They completed the replacement and installation of 5 windows in just under 5 hours with great care and proficiency. After each window was installed, they cleaned and vacuumed the indoor area around the window, which I wasn't expecting. They My wife and I are really happy with our new windows.

Great job!
Edwin showed up before the crew did with two people that worked in offices he explained to them the process of what the replacement process was while Angels crew got to work showing them. Once they left Angel and his guys knocked out the replacement of my ten widows. They covered everything in the rooms with plastic and covered floors so nothing would get dirty. The windows look great they did and great job cleaning up all the mess.

Good experience
We had 12 windows, a front door, a back sliding patio door and a storm door installed. Window Nation kept me informed on each stage of the process. Good follow-through on correcting any concerns/corrections we had. The pricing was very competitive with other window/door companies we interviewed.

Kevin Kinyua our Sales Agent was correct about what products he presented - nice products, professional installers, great service!
Kevin Kinyua our Sales Agent was excellent - what he proposed and what we selected and expected are what we got installed.
Excellent, professional and hard working installers.
Donwside: Need better communication as to when installers were supposed to arrive - we were asked to be ready by 8:00AM when installers were told to be onsite between 8:00AM and 10:00AM, therefore we had to wait for a little over 2:00 Hours before the installers showed up when they (installers) were of the opinion that they were on schedule.
Overall - great job!

Fantastic windows and install!
There were a few snags with Window Nation receiving the windows from the factory. This led to some scheduling shennanigans. Ultimately, we got on the same page, and they came through. The installers showed up on time, they were efficient, and the windows look absolutely AMAZING! We couldn't be more happy.
