How We Price This
These ranges are computed from Burch Contracting's own pricing formula: a base direct cost per square foot — built from current Upstate SC market data, BLS labor statistics combined with local supplier and subcontractor pricing — adjusted for material, complexity, and site conditions, plus a fixed 20% overhead & profit (see services.html for the full comparison). Base rates are reviewed as material and labor costs shift; this page was last updated by C. Scott Burch.
Is this Deck cost estimate accurate?
This is a planning estimate based on typical Upstate SC deck costs, size, and the tier you select — actual pricing depends on your site conditions and finish selections. Every Burch Contracting quote includes a transparent 20% overhead and profit, the same formula used sitewide, with no hidden markup.
What would push my deck project to the high end of this range?
Site access, structural complexity, premium materials, and custom features push a project toward the high end of the range shown above; a straightforward scope in standard materials lands toward the low end. Scott confirms exactly where your project falls during a free consultation.
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.
