A sunroom in Greenville, DE has to do two things at once: open the house up to the yard and still hold its own against a New Castle County winter. As a sunroom builder Greenville, DE homeowners can rely on, SB Builders Group ties the addition into the existing house rather than bolting a kit onto the back of it.
Sunroom Builds We Design
A sunroom is one project with a lot of moving parts: foundation or deck base, framing, roof, glazing, and finish. As a sunroom contractor in Greenville, Delaware, homeowners can vet by license and certification. Here is the range we build:
- Screen Rooms: Roofed, screen-paneled rooms built on a deck or patio.
- 3-Season Sunrooms: Glass-walled rooms for spring-through-fall use.
- 4 Season Sunroom Greenville DE: A 4 Season Sunroom Greenville DE homeowners can use in any season, with insulation, energy-efficient glazing, and heating and cooling.
- Sunroom Addition Greenville DE: A sunroom addition Greenville DE homeowners can match to the existing siding, roofline, and trim.
- Convert Deck to Sunroom Greenville: We convert decks to sunrooms in Greenville by enclosing an existing deck after confirming it can support the added load.
TimberTech and AZEK Composite
SB Builders Group builds with TimberTech and AZEK composite, installed under our Platinum Installer certification. Sunrooms and screen rooms built on a deck base sit on composite decking rather than pressure-treated wood.

In-House Crew: The same crew that starts the sunroom finishes it.
What’s the structural difference between a deck and a sunroom on the same footprint?
A deck carries live load: people, furniture, snow. A sunroom adds permanent dead load, including wall framing, glazing, and a roof, plus lateral load from walls catching the wind. That is why a deck built to standard residential code usually needs reinforced footings, added posts, or a sized beam before it can carry a sunroom.
How is a four-season sunroom kept from losing heat through all that glass?
Insulated glazing units do the work: two or more panes with a sealed gas space between them, rather than the single-pane or storm glass used in a three-season room. The walls and roof are framed and insulated like the rest of the house. Without both, a glass room will not hold heat through a Delaware winter, no matter how hard the HVAC runs.
