Window Nation Honored their Warrenty
Window Nation was tasked with applying new siding to our home. The siding in the dormer area came completely off and in several areas it began to slide. Window nation came out and attached/replaced several pieces. Do to the delay in supplies they were not able to complete the work. As soon as the supplies are in we are assured that they will complete the job. The technicians were very nice and professional. They explained the process before they started and went over the work after they were finished. They even addressed some areas we did not see. We look forward to the completion of the job.

The Windows are top quality and the install only took 4.5 hours for 10 windows. The people I dealt with were all great and the cleanup was perfect.

Great Experience
The crew showed up at appointed time. The three were very organized and efficient. They were very careful about my property to avoid any damage. They were quiet and communicative as needed. They cleaned up as the work progressed. Clearly they were well trained and had worked for WN for sometime. When they were finished, asked me to inspect their install. They cleaned and vacuumed everything. The lead installer then explained the paperwork he was asking to be signed and presented the final invoice for payment.

Team was very knowledgeable about the install, friendly, welcomed questions, on time and went directly to work, efficient- did an overall great job!Of even more importance, the supervisor returned because i had concerns with color match and touchup which he remedied quickly and much to my satisfaction- he was super! Thank you gentlemen- my cats can finally see clearly what's outside!

Absolutely horrible quality of windows and their customer service is even worse. It’s been a whole year experience from hell from dealing with their installers who were not professional who talk like sailors in the front yard to dealing with their incompetent customer service talking to 10 different people to try to get something figured out when I had multiple problems with cracked windows window locks not locking etc. do not buy from them. The quality of Window that they are sellingis not the same as you get.

The service person that came to the house was very pleasant and helpful.
When I called in with the original issue I was very clear on what was wrong and what was needed... The lock for the door completely broke off.... I can't understand why the part wasn't ordered at that original call. So now I'm still waiting and I still have a door that doesn't lock.

The four young men who came to install my windows were so amazing! They were polite and considerate. I couldn’t have asked for a better experience. They worked hard all day installing 20 windows and when they finished you would have never known they were there. They cleaned everything up. The windows are beautiful.
