Had 5 windows replace 2 years ago, hail damage. Had another 3 windows replace 2 months ago and are saving our pennies to have the remaining 3 windows replaced this spring. We did have some communication problems dealing with Nex-Gen for our first order. We understood with the volume of hail damage replacements the schedule for ordering and installing really was troublesome. After getting this resolved, and Nex-Gen making things right, we again were very satisfied with the project.
For our second order we worked with Jason. Jason has the expertise of actually working in the manufacturing plant before being in sales. Jason was involved in the installation and of course the final inspection. Joe did the staining on the interior Everwood for both installations. He took his time to match the existing wood trim and pointed out the changing light in our dining room and tweaked the coverage to best match our preference as to darkness. Again, excellent product and team at Nex-Gen from management, to sales, to installation, to staining and the resultant our satisfaction.
