Company History
The firm began as a small crew of local technicians serving Imperial and neighboring river towns. Over time it grew by focusing on steady, practical work: inspections, repairs, and seasonal service plans. Growth came from repeat customers and connections with property owners across the area.
Work often involves weather-related needs. Summers bring heavy humidity that strains air conditioning. Winters can be cold enough to cause frozen pipes. SM Throop adapted services to those local patterns and the mixed housing stock found in Jefferson County and nearby Illinois towns.
Leadership
Leadership is rooted in hands-on trade experience. The managers and lead technicians came up through apprenticeships and trade school. They stay active in local trade groups and maintain current licenses and certifications.
The company keeps a local presence with response vehicles in and around Imperial. That local footing helps with faster arrival times and better knowledge of area building styles and common issues.
Specialties & Highlights
- Thorough inspections: clear reports for plumbing and electrical systems.
- Responsive emergency service for leaks, heat loss, and electrical faults.
- Work on older homes: experience with aging pipes and legacy wiring.
- Seasonal HVAC maintenance tailored to hot, humid summers and cold winters.
