MGA Plumbing is the Clayton plumbing company to call for water heater installation. Our local plumbers are available 24/7, arrive on time and fix the problem right the first time. Top-rated by Missouri homeowners for fast, clean, courteous work.
Proper installation matters as much as the unit: correct venting, expansion tank, seismic strapping where required, gas sizing and a drain pan can be the difference between a 15-year heater and a 6-year one. We handle permits and inspection.
We install gas, electric, propane, hybrid and tankless water heaters for new construction, remodels and replacements.
