Plumbing Installation & Repair
Water Quality Solutions
A leaking or burst pipe can ruin floors, walls and cabinets in a few hours. Hi-Tech Plumbing Services Inc. finds the leak, fixes it the same day in most cases, and tells you honestly whether the rest of your pipes are healthy or need replacing. We fix the problem first, and we only recommend repiping when it will save you money.
Most pipe problems don’t need a full repipe. Here’s what we fix every week across Los Angeles:
Pinhole leaks are tiny holes that eat through copper from the inside. In the Valley, hard water and high water pressure are the usual causes. We cut out the bad section and put in new pipe with press or solder fittings, then check your water pressure. If it’s over 80 psi, we’ll suggest a pressure regulator so new leaks don’t start. If you’ve had three or more pinhole leaks, the pipe is thinning everywhere, and replacing that run is the smarter fix.
A burst pipe can dump gallons of water a minute. We stop the water, replace the broken section, pressure-test the line and help you dry things out. We can also give you photos and a written report for your insurance claim.
A water stain, soft drywall, a musty smell or a meter that keeps spinning with all taps off usually means a hidden leak. We use leak detection tools like moisture meters and thermal cameras to find it, so we open the wall in one small spot, not five.
Many Valley homes sit on concrete slabs with water lines buried underneath. When one of those lines leaks, breaking the floor is messy and expensive. In most cases we reroute the line through the attic or walls instead, and leave your floor alone. Not sure you have one? Read how to spot a leak under a slab.
Stuck shut-off valves, leaking angle stops, corroded fittings and old braided supply lines cause a lot of leaks. These are quick, low-cost fixes, and they’re worth doing before they fail.



We’ll tell you which one makes sense, even when the answer is the smaller job.

Your situation | What we usually recommend | Why |
One leak, pipes under 30 years old | Repair the leak | The rest of the system is healthy |
2–3 leaks in a year in the same line | Replace that section or zone | That pipe is wearing out; more leaks are coming |
Brown or rusty water, galvanized pipe | Replace the water lines | Rust is inside the whole pipe, not one spot |
Gray plastic polybutylene pipe | Replace it | Known to crack and fail without warning |
Slab leak, older home | Reroute the line | Avoids breaking concrete floors |
Leaks all over a 50+ year-old house | Whole-house repipe | Repairs will keep adding up |
Sometimes a repair isn’t enough. Hi-Tech replaces only the pipes that need it, so you don’t pay for a whole house when one zone is the problem.
Sometimes a repair isn’t enough. Hi-Tech replaces only the pipes that need it, so you don’t pay for a whole house when one zone is the problem.
Galvanized steel pipe was used in many homes built before the 1970s. After 50+ years it rusts inside, which causes brown water, low pressure and leaks. We replace it with PEX-A or copper, room by room or all at once.
Polybutylene is a gray plastic pipe used from the late 1970s to the mid-1990s. It’s known to crack and burst without warning, and some insurers charge more or refuse coverage for homes that still have it. Replacing it protects your home and can make it easier to insure and sell.
If one part of the house keeps leaking, or you’re remodeling a kitchen or bath, we can repipe just that zone in about a day. It’s a smart move during a remodel, since the walls are already open. Ready to replace everything? See our whole-house repiping service. If the problem is your main line or drains, see drain line and water line replacement.
Tell us what you've seen: drips, stains, noises, water bill changes.
We test pressure, check for hidden leaks and look at your pipe type and age.
One clear price before any work starts. Your $75 diagnostic is credited toward it.
Drop cloths and floor covers go down before we open anything.
Every repair and new line is pressure-tested before we leave. Permits are pulled for repiping work, and we meet the city inspector.
We patch the access holes so they're ready for texture and paint, haul away old pipe and show you what we did.
Your price depends on where the leak is, how easy it is to reach, the type of pipe and how much wall or floor we need to open. Typical 2026 ranges in Los Angeles and the San Fernando Valley:
Job | Typical price | Time |
Pinhole leak or small exposed leak | $250 – $650 | 1–2 hours |
Burst pipe repair | $400 – $1,800 | 2–6 hours |
Leak inside a wall or ceiling, with patch | $600 – $2,000 | Same day |
Replace a pipe section (10–30 ft) | $800 – $2,500 | Half day – 1 day |
Partial repipe (1 bathroom or kitchen) | $1,800 – $4,500 | 1 day |
Slab leak reroute (one line) | $2,000 – $5,000 | 1–2 days |
Whole-house repipe, PEX (1,500–2,000 sq ft) | $6,500 – $12,000 | 2–4 days |
Whole-house repipe, copper (same home) | $11,000 – $20,000 | 3–6 days |
What changes your price: after-hours emergency calls (usually 100–300 more), copper vs. PEX (copper runs about 30–60% higher), one-story vs. two-story, slab vs. raised floor, and how much drywall or tile is in the way. About 70–80% of most pipe repair bills is skilled labor, not parts. For more on pricing, see our Los Angeles plumber cost guide.
Pipe | Best for | Why we use it | Typical life |
PEX-A | Repairs, partial and whole-house repipes | Flexible, fewer wall openings, handles hard water well | 40–50 years |
Type L copper | Exposed lines, water heater connections, main lines | Very durable, heat-resistant | 50–70 years |
CPVC | Matching existing CPVC systems | Easy repair on homes that already have it | 40–50 years |

Hi-Tech’s shop is in Winnetka, so we know Valley homes well. Many houses in Winnetka, Canoga Park, Reseda, Northridge and Woodland Hills were built in the 1950s and 60s with galvanized pipe on concrete slabs. That’s why we see so many rusty water lines and slab leaks, and why rerouting is often the best fix.
Valley water is also hard. Minerals build up inside pipes and water heaters, and hard water combined with high pressure helps cause pinhole leaks in copper. A water softener and the right pressure setting help your pipes last longer. We also serve Van Nuys, Encino, Sherman Oaks, Studio City, Burbank and greater Los Angeles.

Most small, easy-to-reach leaks cost 250–650. Leaks inside walls or ceilings run 600–2,000 with patching. Our $75 diagnostic is credited toward the repair.
Repair if it’s one leak and your pipes are under about 30 years old. Consider repiping if you’ve had two or more leaks in a year, have rusty water from galvanized pipe, or have polybutylene. We’ll tell you honestly which one fits.
The most common causes are hard water, high water pressure (over 80 psi) and water chemistry that slowly wears copper from the inside. Fixing the leak and lowering the pressure helps stop new ones.
Turn off the main water valve, turn off the water heater, turn off power near any water, and call us at 818-941-6741. We’re available 24/7.
Most policies cover sudden, accidental water damage from a burst pipe. They usually don’t cover slow leaks or wear and tear. We provide photos and a written report to help with your claim; check your policy for details.
A partial repipe takes about a day. A whole-house PEX repipe usually takes 2–4 days, and copper 3–6 days, depending on size. You can usually stay home, and we restore water most evenings.
Small leak repairs usually don’t. Repiping and replacing water lines typically need an LADBS plumbing permit and inspection. Hi-Tech pulls the permit and meets the inspector for you.
Most of the cost is skilled labor: opening walls, running new lines, connecting every fixture, testing and patching. That’s why fixing only the failing zone, when that’s enough, can save you thousands.
Usually, yes. We reroute the leaking line through the attic or walls, which avoids jackhammering the concrete in most homes.
