Choose Coastline Sunrooms & Awnings for custom sunrooms built to last and designed for coastal living.
A sunroom is typically a fully enclosed structure with large windows or glass panels designed to maximize natural light and extend your indoor living space. Sunrooms can be built as three-season or four-season rooms depending on insulation and climate control.
A porch enclosure converts an existing porch into a protected space using screens, vinyl windows, or glass panels, allowing you to enjoy the outdoors while staying shielded from insects, rain, and wind. The best option depends on how you plan to use the space and whether year-round comfort is important.
Coastline Sunrooms & Awnings offers a wide range of custom solutions, including:
Three-season sunrooms for spring through fall use
Four-season sunrooms with insulation, heating, and cooling
Screened-in porches for airflow and bug protection
