Our Verdict: Custom Window Systems is a strong option for homeowners in hurricane-prone regions who want durable, code-compliant impact windows at a more approachable price point than premium brands. However, homeowners outside the Southeast or those seeking nationwide installation may want to explore other window manufacturers.
This Custom Window Systems review highlights a manufacturer with deep roots in Florida’s coastal construction market. Founded in 1996 and headquartered in Ocala, Florida, CWS specializes in impact-resistant windows and doors engineered to meet stringent hurricane codes.

The company focuses on residential replacement windows and new construction products designed to withstand high winds, flying debris, and extreme weather conditions.
