An Exclusive Product

Our standout feature in Wilmington is the use of Fibrex® material in our products. This composite material merges the strength and stability of wood with the low-maintenance attributes of vinyl. Fibrex® material is known for its durability and energy efficiency, providing a durable yet elegant solution for windows and doors. It’s twice as strong as vinyl, supports larger panes for a more expansive view, and is resistant to warping, rotting, and fading.

The people, product, and installation surpassed all my expectations. Home is noticeably quieter, cooler in the daytime, and each window has a beautiful view as compared to the old aluminum frame.

I love my new windows, made a HUGE difference in the drafts, keeping wind noise out, and keeping heat in. I also choose a different style and the view is much nicer, easier to open and close

Tonya B.

We are extremely pleased with our large dining room window. The old window was not efficient; letting cold air into the house in the winter as well letting heat from the furnace outside! The installer was very professional, efficient and cleaned everything up nicely. The entire experience from sales to installers through follow-up was a pleasure.
