About Wincore
Wincore Windows is a vinyl window and door manufacturer headquartered in Parkersburg, West Virginia. Founded in 2007 by former Simonton executives, the company built its reputation on delivering reliable performance windows at fair pricing through a dealer-only distribution model. Wincore operates over 242,000 square feet of manufacturing across facilities in Parkersburg, Mineral Wells (WV), and Swainsboro, Georgia.
The product lineup includes single-hung, double-hung, casement, sliding, bay, bow, and picture windows plus vinyl patio doors and fiberglass entry door systems. Wincore also manufactures impact-resistant windows for coastal applications. The company deployed fully automated window production lines in 2017, and expanded the Georgia facility by 100,000 square feet in 2020, adding 100 jobs.
Wincore windows are sold exclusively through authorized dealers and professional installers - you won't find them at big box stores. For homeowners replacing windows, qualifying ENERGY STAR certified Wincore products can earn federal 25C tax credits. The dealer-only model means you're working with installers who know the product line.
UniColorado Heating & Cooling is Denver's top heat pump installer, serving homeowners across Littleton, Aurora, Boulder, and the Front Range with cold-climate expertise.
