Plumbing Contractors Serving East San Antonio
Below are plumbing contractors who serve the East San Antonio area. Always verify TSBPE licensing and insurance before hiring.
Plumbing in East San Antonio, TX
East San Antonio covers a broad corridor of established neighborhoods stretching from the inner east side out toward Converse and Kirby, primarily in the 78220, 78222, and 78223 zip codes. The area includes some of San Antonio’s oldest residential communities, with homes dating from the early 1900s through the 1970s and beyond. As a result, plumbing systems in East San Antonio vary widely — from century-old cast iron and galvanized pipes to mid-century copper and newer PVC installations.
Like all of San Antonio, east side homes deal with some of the hardest water in Texas, which accelerates mineral buildup inside pipes, water heaters, and fixtures. Older homes in this corridor are particularly prone to aging drain line failures, slab leaks driven by soil movement, and water heater issues caused by decades of hard water wear. Additionally, many properties in this part of the city sit on expansive clay soils that shift significantly with rain and drought cycles — a known driver of slab and foundation-related plumbing problems throughout the area.
Common Plumbing Services in East San Antonio
Water Heater Repair & Replacement
Tank and tankless water heater repairs, replacements, and new installs. Hard water accelerates sediment buildup and shortens heater life in East SA homes.
Drain Cleaning & Clogs
Kitchen and bathroom drain clogs, slow drains, backed-up sewer lines, and hydro-jetting for stubborn blockages throughout East San Antonio.
Leak Detection & Pipe Repair
Hidden water leaks, pinhole leaks from hard water corrosion, pipe repairs, and water line replacements for East SA homes and businesses.
Slab Leak Detection & Repair
Clay soils on the east side shift with seasonal moisture changes, making slab leaks especially common. Covers detection, trenchless repair, and rerouting.
Emergency Plumbing — 24/7
Burst pipes, flooding, and after-hours plumbing emergencies in East San Antonio. Several local companies advertise same-day and overnight response.
Cast Iron & Galvanized Pipe Repair
Older East SA homes often have original cast iron or galvanized pipes past their lifespan. Covers inspection, lining, spot repair, and full replacement.

About the East & Southeast San Antonio (I-10 East / FM 78) area
East San Antonio stretches from the neighborhoods along I-10 East and FM 78 out to Kirby (78219), Windcrest (78239) and Converse (78109), and past Loop 1604 to the rural communities of St. Hedwig (78152) and Adkins (78101). Inside Loop 410 the housing is mostly mid-century and 1970s; farther out it's newer subdivisions and acreage properties.
Most of the area gets hard, mineral-rich water from the limestone Edwards Aquifer. That speeds up scale buildup in water heaters, faucets and fixtures. The region's expansive clay soils shift between wet and dry seasons, which can stress slab foundations and the pipes under them. The February 2021 winter storm (Uri) showed how vulnerable exposed pipes are to hard freezes. Texas plumbing companies must work under a Responsible Master Plumber (RMP) licensed by the TSBPE, and you can verify the license number using the TSBPE public license search.
