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.
