Why Thornton homes need these repairs

Thornton is a north Denver suburb that grew from 1950s starter homes into large newer subdivisions. Its water starts as Rocky Mountain snowmelt in Clear Creek and the South Platte, stored in Standley Lake and gravel-pit reservoirs, and freezing winters plus expansive soils drive frozen pipe and foundation-related calls.
