Covington's humid climate — shaped by the Yellow River corridor and Newton County's Georgia Piedmont topography — is harsh on older laminate. 2000s-era laminate installed in Covington subdivisions swells at the joints during humid Georgia summers when indoor humidity stays above 60%. Planks that were once tight begin to gap and peak, creating an uneven surface that collects dirt and eventually buckles completely.
Older Covington homes near the historic Covington Square have a different issue: laminate installed over uneven wood subfloors in pier-and-beam construction develops a hollow bounce that sounds and feels poor underfoot. Modern floating laminate requires a flat substrate to within 3/16 inch per 10 feet — older homes need subfloor leveling before any laminate installation will feel right.
