"Should I build a deck or a patio?" is one of the most common outdoor-living questions we get from Upstate SC homeowners. The honest answer depends on your lot, your house, and how you'll actually use the space. Here's a side-by-side breakdown of the real differences in cost, ROI, and livability — based on 2026 Upstate pricing.
Cost: what each actually runs in Upstate SC
- Pressure-treated deck: $30–$45 per sq ft installed. A 300 sq ft PT deck with rail and a single set of stairs runs roughly $9,000–$13,500.
- Composite deck (Trex, TimberTech mid-tier): $50–$75 per sq ft installed. Same 300 sq ft footprint: $15,000–$22,500.
- Premium composite or hardwood (Ipe): $75–$110+ per sq ft. Same footprint: $22,500–$33,000+.
- Concrete patio (broom finish): $8–$15 per sq ft. A 300 sq ft slab: $2,400–$4,500.
- Stamped or stained concrete patio: $15–$25 per sq ft. Same size: $4,500–$7,500.
- Paver patio (concrete pavers): $18–$32 per sq ft. Same size: $5,400–$9,600.
- Natural stone or premium paver patio: $30–$50+ per sq ft. Same size: $9,000–$15,000+.
Roughly: a patio costs 30–50% of an equivalent-size deck for budget tiers, and 40–60% for premium tiers.
ROI and resale impact
Remodeling Magazine's national Cost vs. Value report consistently shows wood decks recouping 60–70% at resale and composite decks 55–65%. Patios are harder to benchmark — they're not a separate line item in most reports — but Upstate appraisers we work with generally credit a well-built paver or stamped-concrete patio at roughly 50–60% of its cost on appraisal. The intangible "buyer wants it" effect is real for both.
Lifespan and maintenance
- PT deck: 15–20 years with diligent staining/sealing every 1–2 years. Skip the maintenance and it's 10–12.
- Composite deck: 25–30+ years. Annual rinse, occasional brush; no staining.
- Hardwood deck (Ipe): 50+ years with periodic oil treatment.
- Concrete patio: 25–40+ years. May need re-sealing every 3–5 years for stamped/stained finishes; can crack with foundation movement.
- Paver patio: 30+ years. Individual pavers can be lifted and re-set if settling occurs — a real advantage over poured concrete.
Which one actually fits your yard?
Pick a deck if: your back door is more than 18–24 inches above grade (a patio there would require expensive retaining walls and steps anyway), you want shade structures like pergolas or covered porches integrated cleanly with the house, or your lot drains poorly and you'd rather build above the wet ground than fight it.
Pick a patio if: your back door is close to grade, you want a fire pit or built-in grill (much easier on a non-combustible surface), you have HOA restrictions on deck height or railing styles, or you're cost-conscious and willing to handle the more limited transitions to the house.
Pick both: some of our favorite Upstate projects combine a small covered deck off the back door (for sheltered transition and outdoor dining) with a larger patio just below it (for fire pit, lounging, and grill area). The two surfaces together create a much more usable outdoor room than either one alone.
