Nice to have an honest company to call on.

I called NexGen for a quote for a new storm/security door. The sales consultant, Ted arrived in a timely manner. After looking at our current door, he said we really didn’t need a new door. Our door does need to be serviced. Nice to have an honest company to call on. Thanks Ted.
