When should I repair versus replace my plumbing in San Antonio?

Repair isolated issues in newer homes. Replace when you have frequent leaks, pipes older than 40-50 years (especially galvanized steel), widespread corrosion, or consistently low water pressure. San Antonio's hard water accelerates pipe degradation, making replacement a common recommendation for older homes.

How much does it cost to repipe a house in San Antonio?

A whole-house repipe in San Antonio typically costs between $4,500 and $18,000. The final price depends on the size of your home, the number of bathrooms and fixtures, the accessibility of the pipes, and the material chosen (PEX is generally more affordable than copper).

Should I DIY or hire a pro for plumbing work?

For very minor tasks like changing a showerhead, DIY is fine. For anything involving cutting pipes, soldering, or main lines, you must hire a licensed San Antonio plumber. Improper repairs can lead to major water damage, void insurance claims, and violate local building codes.

How long do different plumbing pipes last?

It depends on the material. Brass and copper pipes can last 50-70+ years. Galvanized steel, common in older San Antonio homes, typically fails after 40-50 years due to corrosion. PEX tubing, a modern replacement, has a life expectancy of 40-50 years.

What are the warning signs that my pipes need replacement?

Key signs include: recurring leaks, discolored (brownish or yellow) water, visible flaking or corrosion on exposed pipes, a sudden and persistent drop in water pressure throughout the house, and unusual noises like banging or rattling within the walls when water is running.

What the Pros Say

"Look, patching a 50-year-old galvanized pipe is like putting a band-aid on a sinking ship. We see it all the time in Alamo Heights. You fix one leak, and another one springs up a foot away because the whole line is corroded from the inside out."

Mike Johnson

Plumbing Technician, 15 years

"We always present both options, but we encourage homeowners to think about total cost of ownership. Three small repair bills over two years often add up to half the cost of a replacement, without any of the long-term benefits or peace of mind."

Sarah Chen

Service Manager

"In San Antonio, hard water is the enemy. It calcifies galvanized pipes and eats away at copper. When we see low pressure city-wide and discolored water, it's not the faucet—it's the arteries of the house. PEX repiping is often the most durable, cost-effective solution here."

Carlos Rodriguez

Master Plumber

"A whole-home repipe is an investment, not just an expense. It protects your property from the number one cause of homeowner's insurance claims: water damage. It's a selling point, and it's the responsible choice for an older home."
