When Repiping Makes Sense

Not every plumbing problem needs a whole home repipe. But certain situations make complete replacement the smart choice.

Constant repairs:

Fixing leaks in different locations over a year or two
Patching individual leaks has become more expensive than replacing everything once
Repairs are just delaying the inevitable

Old galvanized steel pipes:

Corrode from the inside, narrowing and reducing pressure
Once corrosion starts, it spreads
Common in San Diego homes 50+ years old

Multiple slab leaks:

Each slab leak repair is expensive and disruptive
After two or three, repiping through walls or attics often costs less
Prevents future foundation damage

Polybutylene pipes:

Gray plastic pipes installed in 1980s and 1990s
High failure rates; they become brittle and crack
Repiping eliminates the risk of sudden failures

Frequent pinhole leaks:

San Diego’s hard water accelerates copper corrosion
When pinholes start appearing frequently, the conditions affect all your copper lines
Repiping solves it permanently

Signs Your Home Needs Repiping

Watch for these indicators that suggest complete replacement makes sense.

Frequent leaks – Multiple leaks in different locations over a year or two
Discolored water – Rusty or brown water from corroding pipes
Low water pressure – Persistent pressure problems throughout the house
Visible corrosion – Rust, flaking, or dimpling on exposed pipes
Old galvanized pipes – Original steel pipes in homes 50+ years old
Polybutylene pipes – Gray plastic pipes from the 1980s-1990s
Recurring slab leaks – Multiple leaks under your foundation
Pinhole leaks in copper – Tiny leaks appearing in multiple copper lines

If you’re experiencing several of these, repiping offers better value than endless repairs.

Copper vs. PEX: Understanding Your Options

Both materials work well in San Diego homes and last decades when installed properly. The choice comes down to priorities and budget.

Copper:

Industry standard for over 50 years
Doesn’t degrade from UV exposure
Naturally resists bacteria
Completely recyclable
Lasts 50+ years in most conditions
Higher cost and longer installation time
Every connection requires careful soldering

PEX:

Installs faster with fewer connections
Can bend around corners, requiring less cutting into walls
Resists San Diego’s hard water better than copper
Lower cost than copper
Better freeze protection (less relevant in our climate)
Cannot be used where sunlight hits directly
Proven track record over 30+ years

We’ll explain both options and help you choose what makes sense for your home and budget.

The Repiping Process

Repiping is a major project, but we’ve streamlined it to minimize disruption.

Before work begins:

Thorough inspection of current plumbing
Planning best routes for new pipes (attics, crawl spaces, or walls)
Handle all permits and paperwork with the city

During installation:

Systematic work through your home over 2-3 days
At least one bathroom stays functional so you can stay home
Access holes kept as small as possible
Floors and belongings protected throughout

After installation:

Pressure testing the entire system for leaks
City inspection arranged and passed
Patch and texture wall openings to match existing walls
Minimal signs that major work was done

Repiping Frequently Asked Questions

How much does whole home repiping cost in San Diego?

Cost varies based on home size, number of bathrooms, pipe material, and access difficulty. Most residential repipes range from several thousand to $15,000+. We provide detailed estimates after inspecting your home.

Can I stay in my home during repiping?

Yes, most homeowners stay home. We maintain one working bathroom and restore water service at the end of each workday.

How long does repiping take?

Most homes take 2-3 days for pipe installation, plus time for inspection scheduling and wall repairs. Larger homes may take 4-5 days.

Will you have to cut holes in all my walls?

We minimize wall openings by routing strategically and using access panels. PEX needs fewer access points because it runs longer distances. We patch and texture all openings.

Is PEX as good as copper?

Yes, PEX performs excellently and resists corrosion better than copper in San Diego's hard water. It's been used successfully for over 30 years.

Do you handle permits and inspections?

What warranty do you offer?

All our repiping work is backed by our lifetime workmanship guarantee. Pipe materials carry manufacturer warranties.
