When low pressure, rusty water, and pinhole leaks show up all over the house at once, the problem is usually the pipes themselves — not any one fixture. Many Long Island homes built before the 1970s still run galvanized steel supply lines that corrode from the inside, restricting flow and eventually leaking. Repiping replaces that failing system with modern copper or PEX and solves the whole-house problem at its root.
A water main issue is more urgent. If the main line from the street to your home is leaking or has failed, you may see a soggy spot in the yard, a spike in your bill, a drop in pressure, or discolored water. We repair and replace water main lines and restore reliable service to the house.
Signs You Need This Service
- Low water pressure throughout the house, not just one fixture
- Rusty, brown, or metallic-tasting water
- Repeated pinhole leaks in the same era of piping
- Visible galvanized or old lead-jointed pipe
- A wet or sunken spot in the yard over the service line
- A water bill spike with no change in usage (a possible main-line leak)

Galvanized pipe and Long Island’s older homes
Galvanized steel was standard in homes built through the mid-20th century — which describes a large share of Long Island’s housing, from Levittown and Bethpage to the older sections of Huntington. Over decades, the zinc coating wears away and the steel corrodes inward, choking flow and releasing rust into your water. You cannot clean it out; the fix is replacement.
A whole-home repipe sounds daunting, but done properly it is a planned, contained project that permanently solves pressure, leaks, and water quality. We route the new piping to minimize wall and ceiling openings and restore access points cleanly.
Water main repair and replacement
The water main is the single line delivering all the water to your home, so a failure affects everything. A leaking or broken main can undermine your yard, spike your bill, and eventually cut off reliable service. We locate the fault, determine whether a repair or full replacement is appropriate, and handle the excavation and permitting to get it done. Where possible we use methods that limit disturbance to your landscaping and driveway.
Copper or PEX for a Long Island repipe
Both are excellent, and we help you choose based on your home rather than habit. Copper is rigid, time-proven, and what many Long Island homeowners expect. PEX is flexible, resists freeze damage better, installs with fewer wall openings, and often costs less on labor.
Whichever you choose, the value of a repipe is the same: it permanently solves the low pressure, rusty water, and repeat pinhole leaks that no amount of patching will fix on failing galvanized pipe — and it removes the daily risk of an aging line letting go behind a wall.
Repiping solves what a patch can't
Repeat pinhole leaks and low pressure across the whole house point to the pipe itself. Rather than chase each leak with leak detection and a patch, a repipe fixes it once — and it's the ideal moment to service the water heater and shutoffs while the system is open.
We repipe 1950s tract homes across Levittown and Bethpage. If an aging line has already burst, we respond as an emergency.
Our Process
- 1
Assess the whole system
We evaluate pipe material, condition, and pressure to confirm whether spot repairs or a full repipe is the right call.
- 2
Plan the route
We map the most efficient repipe or main-line replacement path to limit demolition and disruption to your home.
- 3
Install modern piping
Copper or PEX supply lines, or a new water main, installed to code with permits and inspection.
- 4
Restore and test
We pressure-test the new system, confirm water quality and pressure, and patch access points cleanly.
What Affects the Price
We don’t post flat prices, because an honest number depends on your specific situation. For non-emergency work you’ll always get a written scope before we begin. The main factors:
- Size of the home and number of fixtures being repiped
- Pipe material selected — copper vs. PEX
- Accessibility of existing piping behind walls, ceilings, and floors
- For a water main: length of the run and depth of the line
- Whether excavation is required and the surface above it (lawn, driveway, slab)
- Permit, inspection, and any road or right-of-way requirements
