Common Questions

Plumbing Services FAQ

Do you pull permits for plumbing work?

Yes. All plumbing work is performed under Responsible Master Plumber license RMP #46592, and we pull City of San Antonio permits for any work that requires them.

What areas do you cover for plumbing?

We cover San Antonio and surrounding communities including Boerne, Schertz, Helotes, Stone Oak, Alamo Ranch, and Castle Hills.

How much does a water heater replacement cost?

A standard 40-50 gallon tank water heater replacement in San Antonio typically costs between $1,200 and $2,800 including installation. Tankless water heater installations range from $4,500 to $10,000 depending on the unit and whether gas line modifications are needed. We provide a detailed estimate before any work begins.

How do I know if I have a slab leak?

Common signs of a slab leak include unexplained increases in your water bill, the sound of running water when all fixtures are off, warm spots on your floor, cracks in your foundation or walls, mildew or moisture under carpets, and low water pressure. C.S.W. Power Solutions uses electronic leak detection equipment to pinpoint slab leaks without unnecessary demolition.

Do you install water softeners in San Antonio?

Yes. San Antonio has notoriously hard water that damages pipes, appliances, and fixtures over time. We install whole-house water softener systems and reverse osmosis drinking water systems. Installation typically takes 2 to 4 hours. We can recommend the right system size based on your household water usage and hardness levels.

Can you clear a main sewer line?

Yes. We handle main sewer line cleaning, repair, and replacement. We use camera inspection to diagnose the issue — whether it's tree root intrusion, grease buildup, or a collapsed pipe — and recommend the most cost-effective solution. Hydro-jetting, mechanical clearing, and trenchless repair options are all available.

Do you repipe homes in San Antonio?

Yes. We perform whole-house repiping for homes with galvanized, polybutylene, or deteriorating copper pipes. A full repipe typically takes 2 to 5 days depending on home size and accessibility. We use PEX or copper piping and handle all drywall patching and paint touch-up as part of the project.
