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.
How long does it take to build a custom deck?
Most custom decks take 2 to 4 weeks from permit to finish. Simple ground-level pressure-treated decks fall at the shorter end, while elevated, multi-level, or composite decks with railings, lighting, and pergolas take longer. Weather and county permitting timelines can affect the schedule.
Should I choose pressure-treated or composite decking?
Pressure-treated southern yellow pine is the most affordable choice but needs annual cleaning and sealing. Composite decking from Trex, TimberTech, or Azek costs more initially but is virtually maintenance-free, resists fading and rot, and carries 25-year manufacturer warranties. For most homeowners planning to stay long-term, composite pays off over time.
Do I need a permit to build a deck?
Yes. Decks in Upstate SC generally require a building permit and inspections, especially anything elevated or attached to the house. As a licensed general contractor (SC #CLG118679), Burch Contracting handles the permitting and inspections through your county — Greenville, Laurens, or Spartanburg — so you do not have to.
