Slab Leaks, Burst Pipes, and Water Damage Triage
Slab leaks under San Antonio's expansive clay soils show up as warm flooring, rising water bills, low pressure, damp baseboards, and the sound of water running when fixtures are off. We diagnose with electronic listening, pressure isolation, and thermal imaging, and explain reroute, slab-access, and repipe options with real cost tradeoffs before work starts.
Water Heater Repair, Tankless, and Hard-Water Replacement
Standard tank, gas, electric, and tankless water heater installation and replacement scoped against San Antonio hard water, venting condition, expansion tanks, drain pans, T&P valve clearance, and code-required shutoffs. Photograph the data label, top connections, vent, and pan so we can confirm sizing before the truck rolls.
Drain Cleaning, Sewer Line, and Camera Inspection
Clogged kitchen, bathroom, shower, tub, and main sewer drains cleared with mechanical snaking or hydro-jetting. Camera inspection locates root intrusion, bellies, offsets, and broken clay tile on older San Antonio lots. Trenchless repair, spot dig, and full line replacement are quoted with documentation.
Gas Lines, Repipes, and Commercial Plumbing
Gas-line work for generators, ranges, pool heaters, outdoor kitchens, and dryers under RMP46592. Whole-home PEX or copper repipes when galvanized, polybutylene, or failing CPVC has to come out. Commercial plumbing includes backflow testing, grease traps, tenant buildouts, and code corrections.
Frequently Asked Questions
Why are slab leaks common in San Antonio?
San Antonio sits on expansive Bexar County clay soils that swell when wet and shrink in drought, shifting slab foundations and stressing the water lines beneath them. Warm spots on the floor, an unexplained jump in the water bill, low pressure, and the sound of running water with every fixture off are common slab-leak signs.
How much does slab leak repair cost in San Antonio?
Typical 2026 slab-leak projects in San Antonio run about $1,500 to $7,500 including leak detection, access, and modest restoration; reroutes, under-slab tunneling, or a partial repipe can run higher. We locate the leak first and explain reroute, slab-access, and repipe options with real cost tradeoffs before any work starts.
Are you a licensed plumber in San Antonio?
Yes. Plumbing is performed under Texas Responsible Master Plumber license RMP46592, issued by the Texas State Board of Plumbing Examiners and held by the general contractor itself. CSW is veteran-owned (VA Builder #09311).
Can you come the same day for a burst pipe?
We schedule same-day and next-business-day priority visits for urgent plumbing such as burst pipes, active leaks, and no-water situations during business hours (Mon-Fri 7 AM-6 PM, Sat 8 AM-2 PM). Call 210-504-9796 and describe what you see so we bring the right parts.
Can you help with San Antonio hard water?
Yes. Hard water shortens water-heater life and clogs fixtures. We install and service whole-home water softeners, replace tank and tankless water heaters on schedule, and repipe when galvanized or polybutylene lines are failing.
