Custom Sunrooms (3-Season & All-Season)
Sunspace sunrooms offer a seamless transition between your indoor space and the outdoors, adding square footage and elevating your home’s livability. Whether you’re looking to create a cozy three-season retreat or a year-round lounge space, we tailor every sunroom to your home’s layout and your lifestyle needs.
3-Season Sunrooms
Enjoy the fresh air of spring, summer, and fall without worrying about bugs, rain, or fluctuating temperatures. These rooms feature durable framing, large windows, and optional WeatherMaster window panels for added protection and control.
All-Season Sunrooms
Designed with insulation and integrated HVAC compatibility, all-season sunrooms are perfect for Maryland homeowners looking to expand their living space with full year-round comfort.
WeatherMaster™ Window & Wall Systems
If you have an existing porch, deck, or patio structure, WeatherMaster window and wall systems allow you to enclose it without the cost of a full sunroom build. These systems use vinyl-glazed panels that slide and stack vertically, giving you control over ventilation and protection in any weather.
75% ventilation
Virtually unbreakable ViewFlex vinyl
Blocks 99% of UV rays
Custom-built to fit any space, including angled or irregular openings
This system is perfect for homeowners who want the flexibility of a screen room with the added weather protection of a sunroom.
Screen Rooms
Screen rooms are a great way to enjoy outdoor living without pests, debris, or excessive sunlight. Using Sunspace’s aluminum framing and screen systems, we design elegant, breezy rooms that are perfect for outdoor dining, family gatherings, or simply relaxing with a view.
These systems can be freestanding or added to existing patios and porches. And because they’re modular, they can easily be upgraded later with WeatherMaster windows if you decide to convert your screen room into a three-season room.
Patio Covers & Roof Systems
Whether you’re covering a new deck, a poolside patio, or an existing concrete slab, Sunspace patio covers and roof systems offer durable, low-maintenance solutions. Options include:
Insulated Aluminum Roof Panels: Provide temperature control and strength
Acrylic Roof Systems: Let in natural light while blocking heat and UV rays
Custom Gutters & Fascia: Match your home’s aesthetics and support drainage
A patio cover not only provides shade and shelter, but also protects your patio furniture and extends the usable life of your outdoor space.
