Sunroom vs. Screened Porch
Trying to choose? We build both. The right one comes down to how often you want to use the space and whether you want it heated and cooled.
Screened porch
A screened porch uses screen panels, open to the air, great for our warm season, and the lower-cost option, but seasonal.
See screened porches we build
Three-season sunroom
Glass-enclosed rooms for comfortable spring-through-fall use.
Four-season sunroom
A sunroom uses glass and, in a four-season build, insulation and HVAC for true year-round, climate-controlled use. Sunrooms cost more and do more.
Sunroom Styles We Build
A sunroom is glass-and-frame construction tied into the house, closer to a small addition than an enclosure you drop in. We build it to a written scope, schedule, and price before the first panel is set, in every style across Columbia and the Midlands:
Three-season sunrooms
Glass-enclosed rooms for comfortable spring-through-fall use.
Four-season sunrooms
Insulated and climate-controlled for true year-round living.
Glass-enclosed patios
Turn an existing patio or porch into a glass room.
Sunroom + outdoor-living builds
The sunroom built with a new deck or patio as one project.

The parts you don't see
Why Build Your Sunroom With Chonko Construction
A sunroom lives or dies on the parts you don't see: the foundation, the wall tie-in, the flashing, and (for four-season) the insulation and HVAC. We build it as a licensed home builder: a proper foundation, a weather-tight connection to the house, and glazing and insulation matched to how you'll use the room.
Because we're a full home builder, we can build the sunroom on a new deck or patio as one project, not just set an enclosure on what's already there. The scope, schedule, and price are in writing before any work starts, so the number you sign is the number you pay.

What Drives the Price
Every sunroom is different, so we set the exact number in writing after we walk your space. A few things move it most:
- windowSize & glass area, more square footage and more glass scale the cost.
- calendar_monthThree- vs. four-season, insulation and HVAC for year-round use add cost over a three-season room.

Want real numbers? Our Midlands sunroom cost guide breaks down three-season vs. four-season price ranges. Whatever your number, it's set in the contract before we break ground, no surprise billing.
Sunrooms in the Midlands
A sunroom is how you enjoy the Midlands' long, bright seasons without the heat, pollen, and bugs. We build for our climate: glass and glazing chosen for the South Carolina sun, a four-season option insulated and conditioned for July and January alike, and a weather-tight tie-in that keeps our summer storms out. The result is a bright room you actually use year-round, not just on the mild days.

Frequently Asked Questions
What is the difference between a sunroom and a screened porch?add
A sunroom has glass windows and is typically insulated, allowing year-round use in any weather. A screened porch has screen panels for airflow and insect protection but is not climate-controlled. Sunrooms cost more; screened porches are seasonal. Chonko Construction builds both in Columbia and the Midlands.
What is the difference between a three-season and four-season room?add
A three-season room is enclosed with glass but not fully insulated or tied into HVAC, comfortable spring through fall. A four-season room is insulated and climate-controlled for year-round use. Chonko Construction builds both depending on how you want to use the space.
How much does a sunroom cost in Columbia, SC?add
Sunroom cost depends on size, glass, insulation, and whether it's three- or four-season. Every Chonko Construction project starts with a written scope, schedule, and price before work begins, so the number is clear up front. See our Midlands sunroom cost guide for three-season vs. four-season price ranges.
