If your Delray Beach home or condo dates to the 1960s or ’70s, its original water supply was almost certainly copper. Copper lasts a long time — but in a salty, humid coastal environment it eventually pits and springs pinhole leaks, and a lot of that pipe is now reaching the end of the line.
Why this matters in Delray Beach
Delray Beach grew quickly in the mid-twentieth century, and a large share of its single-family homes and low-rise condos were plumbed in copper. Three local factors tend to shorten copper’s working life here:
- Coastal salt air and humidity accelerate corrosion, especially on lines run through hot attics and exterior walls.
- Water chemistry can drive internal pitting, where tiny perforations form from the inside of the pipe.
- Age — copper installed 50–60 years ago is simply at the stage where pinholes start appearing in clusters.
Because so many homes hit this point around the same time, whole-home repipe is one of the most common big-ticket plumbing projects in the area — for both houses and aging condo units.
Signs your copper may be due for a repipe
- Repeated pinhole leaks — especially more than one on the same system within a year or two
- Green or blue-green staining on pipes, fittings, or around fixtures
- Discolored water or a metallic taste, particularly on the first draw
- Weak or steadily declining water pressure across multiple fixtures
- Stains on ceilings or walls, or a spike in the water bill with no obvious cause
- A history of patch repairs that keep moving to new spots on the line
Slab leak on a Delray Beach home?
If the pinholes are in copper lines routed under your slab rather than in the walls and attic, that is a slab leak — a related but distinct problem with its own detection and repair path. See our companion page: Slab leak detection & repair in Delray Beach →
Your repipe options
PEX
PEX is flexible cross-linked polyethylene tubing. It routes quickly with fewer fittings, tolerates the water conditions that pit copper, and is widely used across Florida. It is often the faster, less disruptive choice for a supply repipe.
Copper
Copper is rigid, long-established, and preferred by some owners for its track record. A repipe in copper costs more in materials and labor than PEX. A licensed plumber can weigh the two against your layout, water chemistry, and whether you are in a house or a condo with shared walls.
What affects the cost
- Home size & number of bathrooms — more fixtures means more pipe and more connections.
- Material choice — PEX vs. copper changes both material and labor cost.
- House vs. condo — condo work adds coordination, access, and HOA approvals.
- One vs. two stories and attic access — routing difficulty drives labor.
- Drywall, tile, and finish restoration after the work
- Permit and inspection fees through your local building department
| Scope of work | Directional planning range |
|---|---|
| Whole-home supply repipe in PEX | $5,000 – $13,000+ |
| Whole-home supply repipe in copper | $8,000 – $20,000+ |
| Condo unit repipe | $4,000 – $12,000+ |
| Single pinhole / spot repair | $350 – $1,200 |
Permits & who can do the work
Repiping is permitted work in Florida. In Delray Beach the permit and inspections run through the City of Delray Beach building department; in unincorporated pockets they run through Palm Beach County’s building division (the “authority having jurisdiction,” or AHJ). Work should be performed by a Florida state-licensed plumbing contractor, who normally pulls the permit and schedules the required inspections. If you are in a condo or HOA community, also clear the work with your association. Confirm current permit fees and requirements with your specific AHJ — they vary by municipality and change over time.

Frequently asked questions
Why does copper pipe leak in Delray Beach homes?
Copper has a long lifespan, but coastal South Florida is hard on it. Salt air, humidity, water chemistry, and decades of use can cause pitting from the inside out, producing pinhole leaks.
Homes from the 1960s and 1970s are now reaching the age where these pinholes start appearing in clusters rather than one at a time.
Copper or PEX for the repipe?
Both are used widely in Florida. PEX is flexible, fast to route with fewer fittings, and resistant to the pitting that affects copper; copper is rigid, time-tested, and preferred by some owners.
A licensed plumber can recommend based on your layout, water chemistry, and whether you are in a single-family home or a condo with shared walls and HOA rules.
Can a condo be repiped, and who approves it?
Yes. Many older Delray Beach condos have aging copper inside the units. The in-unit supply lines are usually the owner’s responsibility, while risers and common lines belong to the association.
Repiping a unit typically needs HOA or condo association approval and coordination with neighbors. Confirm the scope and approval process with your association before you start.
Is one pinhole leak a reason to repipe the whole house?
Not always — but a pattern is. A single leak can be a spot repair. When you start seeing repeated pinholes on the same system, the underlying copper is usually degrading throughout, and patching one spot just delays the next leak.
A plumber can assess whether spot repairs or a full repipe makes more sense for your home.
How long does a whole-home repipe take?
A supply repipe on a typical single-family home is often a few days of plumbing plus drywall patching afterward. A condo unit can sometimes be faster.
Your plumber can give a schedule after inspecting the home and confirming access.
Do I need a permit?
Yes — repiping is permitted work. Your licensed plumbing contractor typically pulls the permit through the City of Delray Beach building department (or Palm Beach County for unincorporated areas) and schedules inspections.
Verify current fees and requirements with your authority having jurisdiction.
