Mad Hatter STL Service Area: Communities We Serve in the Greater St. Louis Region

Our Service Area: Proud to Protect Greater St. Louis Homes

Since 1978, The Mad Hatter has been the St. Louis metro area's most trusted name in chimney and air duct services. As a second-generation, family-owned business headquartered in O'Fallon, Missouri, we have built our reputation by delivering forensic-level diagnostics and uncompromising craftsmanship to homeowners throughout the region. Below is a complete overview of the communities we proudly serve.

Primary Service Areas

O'Fallon, MO — Our Home Base

Located at 1109 Old East Terra Lane, O'Fallon, MO 63366, our main office and dispatch hub serves this thriving community first. O'Fallon is one of Missouri's fastest-growing cities, and its mix of established neighborhoods and newer developments means our technicians address everything from aging masonry fireplaces in classic ranch-style homes to modern gas inserts in newly constructed residences.

St. Charles, MO

St. Charles is a key community in our service area, with historic homes along Main Street that often feature original masonry chimneys requiring expert restoration. Our Level II camera inspections and IRC-compliant relining solutions keep St. Charles households safe through Missouri's punishing freeze-thaw cycles.

St. Peters, MO

St. Peters residents trust The Mad Hatter for chimney sweeping, air duct cleaning, and dryer vent services. With extensive residential subdivisions and high HVAC usage year-round, our industrial-grade American Caddy Vac extraction system delivers medical-grade air quality results for families throughout St. Peters.

Wentzville, MO

As one of Missouri's most rapidly expanding communities, Wentzville features thousands of newly built homes — many with factory-built fireplaces and prefab chimney systems. The Mad Hatter's certified technicians are fully trained to service all system types, ensuring new construction and existing homes alike maintain maximum safety and efficiency.

Lake Saint Louis, MO
