How We Price This
These ranges are computed from Burch Contracting's own pricing formula (base cost per square foot, adjusted for material, complexity, and site conditions, plus a fixed 20% overhead & profit — see services.html for the full comparison). The real-world data source behind the base rates themselves is not yet published. Updated by C. Scott Burch.
What is the difference between a screened porch and a three-season room?
A basic screened porch uses fiberglass screening for bug-free open-air use. A three-season room upgrades to an EZE-Breeze vinyl window system for adjustable ventilation. A premium climate-controlled porch adds insulated walls, roof, and an HVAC extension for true year-round comfort.
How long does it take to build a screened porch?
A screened porch typically takes 3 to 6 weeks depending on whether we are building on a new foundation or converting an existing deck, and on the finish level. Premium climate-controlled builds with HVAC and interior finishing take longer than a basic screened enclosure.
Can you convert my existing deck into a screened porch?
Yes. Converting an existing deck or concrete pad into a screened porch is one of the most common projects we do. We assess the existing structure to confirm it can support the roof and screening system, then handle framing, screening, electrical, and finishing.
