We install the Joyce Oasis® Collection for homeowners throughout Greeneville and Greene County.

A well-planned sunroom should provide more than extra square footage. It should be comfortable, functional, visually connected to your home, and built with materials selected for long-term performance. The Window Source of the Tri-Cities brings those priorities together with the Joyce Oasis® system and professional installation.
Some homeowners want a large gathering area, while others envision a quiet space filled with sunlight. We start with your priorities rather than assuming how the room should be used, helping you make design choices that support the space you actually want.
From evaluating the installation area to completing the final walkthrough, our team brings extensive exterior home improvement experience to the project. Our knowledge of windows, glass, framing, and weather sealing is especially valuable when creating a room surrounded by large expanses of glass.
Joyce Oasis® sunrooms feature an all-vinyl wall system designed for thermal efficiency and minimal maintenance. SmartShield insulated glass, SuperSpacer warm-edge technology, and the ClimateMaster® Roof work together to create a system engineered for four-season performance, while our Certified Master Installers handle the construction.
Our team combines product knowledge, thoughtful planning, and professional craftsmanship to create a sunroom that becomes a useful and inviting part of your Greeneville home.

Will The Window Source help me figure out the best layout for my Greeneville sunroom?
Yes. During your consultation, we'll look at your home's layout, available installation area, and how you want to use the room before recommending design options.
Can a sunroom give me more living space without feeling closed off?
That's one of the main advantages of a sunroom. The Oasis® system maximizes the glass viewing area, allowing you to gain enclosed living space while maintaining abundant natural light and outdoor views.
What makes Joyce Oasis® different from a basic patio enclosure?
Oasis® is designed as a true four-season system with insulated vinyl walls, high-performance glass, an engineered roof, and weather-tight construction rather than a simple seasonal enclosure.
Can I explore financing before committing to the project?
Yes. Qualified homeowners can explore available financing and pre-qualification options as they consider their sunroom project.
What does The Window Source handle once I approve my project?
Our team coordinates measurements, custom manufacturing, required permits, and professional installation, then completes a final walkthrough with you once the project is finished.
