About Us

Design Meets Craftsmanship, Sunlight Meets Style

At Great Lakes Sun Management, we believe window coverings should do more than filter light—they should elevate your home.

Founded by Erin Liberty, a seasoned interior designer, and Brett Zandstra, a master craftsman and contractor, we’ve combined our talents to offer a full-service, high-quality window treatment experience for homeowners across Chatham-Kent and Southwestern Ontario. Our goal is simple: to make your space more beautiful, more functional, and fully aligned with your lifestyle.

Backed by Elite Window Fashions, a trusted Canadian brand since 1967, we supply and install custom blinds, shades, and drapery that are made right here in Canada. From soft sheer shades to bold blackouts and innovative motorized options, we help you choose the perfect solution for your light control, privacy, and aesthetic needs.

Whether you're completing a renovation or simply refreshing a room, we bring design expertise and construction precision together—offering both style and peace of mind.
