Two apposable digits way up.
The three men who came to replace my windows were kind and very good at their jobs.
Being someone who finds issues with every single thing, I am happy to report no issues.
Window nation also beat everyone else in price by a substantial amount without sacrificing quality. They were the goldilocks company for us.
Very pleased overall.

Why weren't proper parts ordered before repair visit?
The technician who came to our home to do repairs was friendly and he efficiently swapped in a half-dozen latches. However, the main purpose I submitted a repair request was two windows that won't stay open due to broken coil balances. This was noted in my written request, along with the window model name and several photos of the issue. As soon as the technician walked in, he said Window Nation would need to order those parts. What the heck? If Window Nation needed more info or photos from me in order to have parts ready, all they had to do was ask! Now, I have to wait on the parts, schedule another repair appointment, and make myself available all over again. This could/should have been unnecessary.

Excellent workmanship
The staff were polite and friendly and kept us informed of what they were doing and asked questions when they were unsure. They worked quickly but with care and all windows and trimming look great. They cleaned the work site up and took everything away.

Happy with my sliding glass door
The price, ease of scheduling and installers who were friendly, knowledgeable and on time to was inpressive. I gave 4 stars only because I asked for locking hardware and somehow it was overlooked but I got a call from WN and they said they'd make it right. The screen door track is plastic and I hope it holds up. And the 1.5% charge for credit card purchases is disconcerting, to avoid it you have to pay by cash or check. Other than that, I'm happy with my purchase and hope the door lasts a long time.

We acknowledge your concerns about the screen door track and credit card charge. We value your feedback and hope you enjoy your door for years to come.
