6+ Room New Window Service
Having your window pop and shatter suddenly without cause is a startling experience but what is more shocking is the absolute horrible customer service and blatant disregard for their warranty and care for the customer. And that is what sold us on this company.
We have had one of the shatter windows replaced but it took around 6 months to get it done. And this one that is still broken and waiting to be replaced? we have been waiting nearly a year and can?t get a call back or an update.
To add to the troubles, the initial install ended up being awful. It looked great for a bit but all the windows have gaps and dirt and air pass through and they are a MESS!!! Mike from Nex-Gen came and walked through everything and agreed the installation was not good. And he promised to get the replacement in quickly for the broken window and would fix all these install issues and wrote everything down and apologize but, that was nearly 5 months ago and we have called and have gotten NO response.

Mike was our installer and we are glad. He worked from the time he arrived, and showed a level of professionalism that is uncommon nowadays.

Mike was our installer. He was beyond terrific. His work was sound. He fixed unforeseen problems. He was pleasant, hardworking and dedicated to meeting the time lines. We donâ t have any criticisms or complaints. As to the supplier, we have equally good feelings. This entire experience was great and â as advertisedâ . For any homeowner looking for a bathroom makeover, this company and this installer are â acesâ .

The installer was excellent! He worked so hard the two days he was here, and his work was impeccable. The financing was difficult to work through, and we were passed from person to person over several days. I would have given 5 stars for everything if it wasn't for the financing trouble.
