About Us
Where Performance Meets Partnership
With over 50 years of combined experience in construction and development, Capital Window Supply was built on a simple goal — to make sourcing windows and doors seamless, transparent, and cost-effective.
We go beyond simply selling products by delivering a responsive, knowledgeable, and partnership-driven experience. Our team understands what it takes to keep a project on schedule and within budget — because we’ve been on the builder’s side of the table.
Your Trusted Partner
With deep roots in the building industry, we understand that your success depends on more than price alone. Our goal is to make sourcing windows and doors seamless and efficient by combining competitive pricing, broad product options, and reliable communication from takeoff through delivery.
Premium Products
Through longstanding relationships with industry-leading manufacturers, we offer access to a wide range of premium window and door brands and products, allowing us to tailor every package to meet each project’s design, performance, and budget requirements without the limits of a one-size-fits-all solution.
Our network gives us the flexibility to deliver solutions across a wide range of applications.
Personalized Project Approach
At the intersection of performance and partnership, we deliver solutions to meet your project goals - not someone else's sales targets.
Our collaborative approach ensures you get the right product at the right value, every time.
