Memphis homes sit on loess soil that moves more than people expect, especially after long dry spells followed by heavy rain. That movement nudges door frames out of square, which is why storm doors sometimes bind or leave gaps if they’re not fitted right. Add in our thick summer humidity and the wild spring storm season, and door materials expand, contract, and flex under wind load. We’ve seen enough Midtown bungalows and East Memphis ranchers to know how these weather swings affect alignment, so we trim, shim, and anchor storm doors to handle that motion. Local suppliers like Home Depot on Poplar and Lowe’s along Winchester keep stock of aluminum and composite-frame storm doors that resist moisture and hold up better through our storm cycles.
