Window Replacement in South Carolina: Local Market Insights
South Carolina experiences a humid subtropical climate with long, hot, humid summers and short, mild winters. Construction runs year-round, but the Lowcountry from Charleston to Hilton Head faces full hurricane exposure, and the state's distinctive expansive marine clays drive foundation engineering costs along the coastal plain. For window replacement projects specifically, this means timing and material selection are key factors in both cost and quality.
A larger pool of available contractors and moderate demand create competitive pricing in this market.
