Eric G: 5 Common Reno Mistakes for Greenville Homes
The Home Depot — Greenville
ERIC G · RENOVATION EXPERT
I’ve seen the same five mistakes derail renovations across the HERE City Network. Here’s how they play out specifically in Greenville and the broader Upstate — and how to avoid them.
Mistake 1: Ignoring the Upstate humidity profile — Greenville’s summer humidity (70–85% mornings in July) destroys work done with the wrong materials. I see this most often with flooring: solid hardwood cupping in poorly-sealed crawl spaces, laminate bubbling near exterior doors, and unprimed drywall compound cracking in bathrooms. Vapor barrier first. Always.
Mistake 2: Pulling permits you don’t need, skipping ones you do — In Greenville County, structural work, electrical panel upgrades, HVAC replacements, and additions require permits through Greenville County Building Services. Deck replacements on the original footprint often don’t. The confusion costs money both ways: over-permitted cosmetic work slows you down; under-permitted structural work creates title problems when you sell.
Mistake 3: Not accounting for the Greenville sandy soil — Upstate Cecil red clay over saprolite compresses differently than Upstate clay or Lowcountry pluff mud. Footings that work everywhere else can settle here. For any deck addition, room addition, or garage conversion, get a soil test before pouring. Greenville-area engineers know this profile; out-of-market contractors often don’t.
Mistake 4: Hiring unlicensed general contractors — South Carolina requires contractor licensing for any project over $5,000. In the Greenville market, unlicensed operators charge 20–30% less and deliver variable results. Check license status at llr.sc.gov before signing any contract.
Mistake 5: Starting exterior paint in peak summer — Greenville’s July-August heat (highs near 95°F, direct sun surface temps exceeding 110°F) prevents most latex paints from curing correctly. The ideal exterior painting window in the Upstate is April–May or October–November. Starting in summer to “save time” typically means redoing the work within 18 months.
