MGA Plumbing is the De Soto 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. Thousands of 5-star reviews from Missouri families and businesses.
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.
Because we dispatch from the St. Louis Metro area, a MGA Plumbing plumber can usually reach any address in De Soto fast — including St. Louis and O'Fallon. For water heater installation emergencies, that speed is the difference between a simple repair and major water damage.
