Kennett Square sits in southern Chester County, the Mushroom Capital of the World, a town of stone farmhouses, restored Longwood-area estates, and newer custom homes. SB Builders is the sunroom builder Kennett Square, PA, homeowners hire when the project calls for a code-compliant addition that ties into the existing house, not a prefab aluminum kit dropped onto an old deck.
Sunroom Builds We Design
As the sunroom contractor in Kennett Square homeowners hire, we design, frame, and finish each build as a single coordinated project.
- Screen Room Kennett Square: Roofed, screen-paneled rooms built on an existing deck or patio, with a framed gable or shed-style roof matched to the house.
- 3-Season Sunrooms: Glass-walled rooms for spring-through-fall use, framed and roofed to match the existing house.
- 4 Season Sunroom Kennett Square PA: A 4 Season Sunroom Kennett Square PA homeowners can use in any season, with insulation, energy-efficient glazing, and integrated heating and cooling.
- Sunroom Addition Kennett Square: Permanent home additions matched to the existing siding, roofline, and interior trim.
- Patio and Deck Enclosures: Converting an existing patio or deck into a screened or enclosed room.
Roof, Floor, and Ceiling Details
- TimberTech and AZEK Composite Floor: Sunrooms and screen rooms built on a deck base sit on TimberTech or AZEK composite decking, installed under our Platinum Installer certification. No pressure-treated wood floors.
- Matched Shingle Roofs: Gable or shed-style framed roofs with shingles matched to the existing house, integrated at the roofline rather than bolted on.
- Tongue-and-Groove Vaulted Ceilings: Painted T&G ceilings with vaulted or cathedral profiles, paired with ceiling fans and recessed lighting on most builds.
- Stick-Built Framing: Dimensional lumber wall and roof framing rather than pre-cut aluminum kits, so the room reads as part of the house.

What Happens Before the First Cut
Before any framing starts, we map how the new roof will integrate with the existing roofline, confirm the deck or foundation can carry the added load, and lay out the ceiling structure so the finish ties in cleanly. The estimate you get back reflects that work, not a guess.
