[40+ Years of Experience]
Bring more natural light and usable living space into your home with a custom year-round sunroom from The Window Source of the Tri-Cities. We install the Joyce Oasis® Collection, an all-vinyl sunroom system designed for true four-season use throughout Northeast Tennessee and Southwest Virginia.
Unlike a screened porch or three-season room, an all-season sunroom is fully enclosed and insulated so it can be heated and cooled along with the rest of your home. Enjoy the outdoor views you love without giving up protection from summer heat, winter temperatures, rain, wind, or insects.
Whether you envision a quiet morning room, a bright home office, or another place for friends and family to gather, we'll help you create a sunroom designed around your home and the way you want to use it.

The Tri-Cities experiences four distinct seasons, which means an outdoor space that works well in spring may not be nearly as useful in January or July. A year-round sunroom gives you the connection to the outdoors while providing the insulation and protection needed for changing temperatures.

The Joyce Oasis® system is designed to hold conditioned air, allowing your sunroom to be heated and cooled for comfortable use throughout the year.
Large expanses of glass create an open, bright environment while preserving views of your backyard and surrounding property.
A sunroom can become a dining area, home office, reading room, hobby space, entertaining area, or simply another comfortable place to unwind.
Enjoy the scenery and changing seasons without dealing directly with rain, wind, insects, or uncomfortable temperatures.

The Window Source of the Tri-Cities installs the Joyce Oasis® Collection, a premium all-vinyl sunroom system engineered for lasting performance and year-round use.
Joyce's proprietary vinyl blend provides thermal efficiency, long-lasting color retention, and a low-maintenance finish designed specifically for sunroom construction.
The insulated ClimateMaster® Roof provides structural strength, thermal performance, and lasting protection as an integral part of the Oasis® system.
Smartshield insulated glass combines low-E technology with SuperSpacer warm-edge foam spacer technology to support thermal performance, argon gas retention, and reduced condensation.
Tempered safety glass comes standard on the windows and is designed to provide additional strength and protection for your new living space.
Concealed electrical raceways and hidden screws and fasteners help give the finished room a polished appearance without unnecessary hardware interrupting the design.
The Oasis® framing system maximizes the amount of glass in your sunroom, giving you more natural light and clearer views while still making it easy to add blinds or curtains.

A sunroom should feel like it belongs with your home rather than looking like an afterthought. That's why each Oasis® sunroom is planned around your existing property, available space, and design preferences.
Choose from available Oasis® wall styles and colors to coordinate the new addition with your home's siding, trim, roof, and other exterior features.
The size and configuration of your sunroom can be planned around both your property and what you want to do inside the finished space.
Because the Oasis® system is fully insulated, your sunroom can be heated and cooled. Depending on your home and project, climate control may be provided through the existing HVAC system or a dedicated solution such as a mini-split.
Concealed electrical raceways allow outlets and other electrical features to be incorporated without compromising the room's clean finished appearance.
We'll walk you through the available options during your free in-home consultation.

Adding a permanent room to your home involves more than selecting a style. Our team helps coordinate your sunroom project from the first conversation through professional installation.
We visit your home, evaluate the proposed area, take initial measurements, discuss how you want to use the room, and show you available product and design options.
We'll help you determine the appropriate room configuration and choose glass, colors, finishes, and other features for your project.
Precise measurements are taken so your Oasis® sunroom can be manufactured specifically for your home.
Joyce manufactures the components of your Oasis® sunroom according to the specifications developed for your project.
Our team handles required permits and coordinates applicable local building requirements before installation.

A sunroom combines windows, glass, roofing, insulation, weatherproofing, and structural components into one finished addition. The Window Source of the Tri-Cities brings exterior home improvement experience together with the Joyce Oasis® system to help homeowners create rooms built for long-term use.

Your sunroom starts with a conversation about what you want from the space. We'll consider your property, preferred room use, design ideas, and budget before helping you compare the available options.
Windows and glass are a major part of any sunroom. Our experience with replacement windows, insulated glass, framing, and weatherproofing gives our team valuable knowledge when planning and installing a glass-filled addition.
The Joyce Oasis® Collection brings together an all-vinyl wall system, insulated ClimateMaster® Roof, Smartshield insulated glass, and tempered safety glass in a system engineered specifically for year-round sunrooms.
From choosing the roof style to completing the installation, our team helps Abingdon homeowners create covered outdoor areas designed to look finished, function well, and provide lasting value.

We want the exterior of your home to be a beautiful reflection of your style and tastes. Whether you want to upgrade your home’s entrance with a beautiful wood door with a surround or you want to replace your aging sliding glass door to the deck, we have all your home replacement needs covered.

Learn MoreWhat can I use a year-round sunroom for?
Sunrooms are highly versatile. Homeowners use them as sitting rooms, home offices, dining areas, hobby spaces, plant rooms, entertaining areas, and additional places for families to gather.
Can my sunroom be heated and cooled?
Yes. The Joyce Oasis® system is fully insulated for year-round use. Depending on the project, the room may be connected to your home's HVAC system or use a separate climate-control option such as a mini-split.
Can you build a sunroom on an existing patio or deck?
In many cases, an existing concrete slab or deck may be usable, but it needs to be evaluated first. We'll inspect the existing structure during your consultation and explain if modifications or additional foundation work may be necessary.
Will my sunroom be custom-made for my home?
Yes. Measurements, room configuration, colors, glass, and other available options are selected around your specific property and project.
Does The Window Source handle sunroom permits?

The Joyce Oasis® lifetime warranty covers the all-vinyl wall system, ClimateMaster® Roof, Smartshield insulated glass, including glass breakage, and hardware for as long as you own the home. It can also be transferred once to a future homeowner.
