Student rentals & turnover maintenance
Near Texas State University, frequent tenant turnover can stress fixtures and valves. We clear slow drains, repair running toilets, replace worn cartridges, and handle quick-turn water-heater diagnostics so units are move-in ready with minimal downtime for property managers and new students.
Hays County water notes: scale, PRVs & hot-water wait times
Mineral scale is common locally and can reduce hot-water flow or cause temperature swings. We descale tankless heat exchangers, flush tank heaters, and check pressure-reducing valves (PRVs) and thermal expansion control to protect fixtures and maintain steady pressure. For long plumbing runs, we can design or tune hot-water recirculation to shorten wait times at remote baths.
Permits & inspections in San Marcos
When a project requires permitting (e.g., water heater replacement, repipes, major alterations), we pull the permit and coordinate inspections with the City of San Marcos. During your estimate we’ll confirm if permitting applies and outline steps, timing, and any access needs.
