Frequently Asked Questions

  • What types of sunrooms do you build?

    We offer a range of sunroom options including three-season rooms, four-season rooms, screened porches, and full room additions with insulated glass and climate controls. You choose the level of comfort and usability you desire.

  • How much does it cost to build a sunroom in Rock Hill, SC?

    The cost depends largely on size, materials (glass type, framing, insulation), foundation work, roof tie-ins, utilities (HVAC, electrical), and whether you convert an existing space or build an addition. After a site visit, we’ll provide a customized, transparent estimate.

  • Do you manage permit applications and inspections?

    Yes. We handle all required permitting, structural design review, and inspections in Rock Hill and surrounding jurisdictions. You don’t have to worry about code compliance — we take care of it.

  • Can you integrate the sunroom with my current home design?

    Absolutely. We design the sunroom to complement your home’s architecture and materials, matching rooflines, siding, trim, and finishes, so the addition looks like a seamless extension of your home.

  • Will my sunroom be usable year-round?

    If you choose a four-season sunroom—with proper insulation, energy-efficient glass, and HVAC or heating/cooling—yes. Otherwise, three-season rooms provide sheltered use in spring, summer, and fall, but might require supplemental heating in winter.

  • How long does sunroom construction take?

    A typical sunroom project takes several weeks to few months from conception to completion, depending on complexity, permitting, and weather. We’ll give you a schedule after design approval so you know key milestones.

  • Can you convert an existing porch or patio into a sunroom?

    Yes. We can enclose existing porches or patios, reinforce foundations or framing if needed, and retrofit insulation, windows, and finishes to transform it into a comfortable sunroom.

  • What materials and glass options are available?

    You can choose from materials such as aluminum, vinyl, wood, or fiberglass for frames, and options like double- or triple-pane insulated glass, low-E coatings, tempered glass, and decorative grid patterns. We help you pick what best suits your climate and budget.

  • How is the sunroom foundation handled?

    Depending on the project, we may extend the existing foundation or pour a new slab or footings. Foundation work considers soil conditions, drainage, and structural loads to ensure long-term performance.

  • What is included in the installation process?

    Our full-service process includes design and consultation, 3D modeling, engineering, permit acquisition, foundation work, framing, window/glass installation, roofing tie-ins, insulation and interior finishes, electrical, HVAC hookups (if needed), and final cleanup.

  • Do your sunroom projects come with a warranty?

    Yes. We back our workmanship with a warranty, and many materials (e.g., glass, frames) include manufacturer warranties. We’ll clarify all warranties before construction begins.

  • What areas do you serve?

    We serve Rock Hill, Fort Mill, Clover, Indian Land, York, Lancaster, Chester, and surrounding communities in the region of South Carolina.
