Chesterfield, Missouri (ZIPs 63005, 63017) is the largest city in St. Louis County by both population and geographic area. Its housing stock is predominantly 1980s-2010s construction: large-format homes in master-planned communities like Baxter Estates, Clarkson Valley, and Long Meadows. The plumbing issues differ from inner-ring suburbs: water heater replacements in large homes requiring 50-75 gallon or multi-unit systems, irrigation system winterization and startup, and expansion vessel requirements under current code. Average household incomes above $120,000 produce buyers who expect quality, responsiveness, and professionalism over price minimization.
