Leak Detection & Pipe Repair

The leaks you cannot see are often the ones doing the most damage — we find them fast and fix them right.

A leak you can see is one thing. A leak inside a wall, under a slab, or buried in the ground is a different problem entirely. By the time most homeowners notice the signs — a higher water bill, a damp spot on the floor, the sound of water moving when nothing is running — the damage has already been building for a while. At Smith Plumbing, we take leak detection seriously because the cost of finding it late is almost always higher than the cost of finding it early. We locate the source accurately before opening anything up unnecessarily.

The High Desert puts real stress on residential plumbing. Extreme temperature swings between hot summers and freezing winter nights cause pipes to expand and contract repeatedly, which weakens joints, cracks fittings, and opens up pinhole leaks over time. We factor that into how we approach detection and repair in homes throughout Hesperia, Oak Hills, Phelan, Victorville, and Apple Valley. When we find the leak, we repair it properly — not with a temporary fix that holds for a season and fails again.

If your water bill has gone up without explanation, or you have noticed any of the signs of a hidden leak in your home, call Smith Plumbing at (760) 220-8120. We serve homeowners across the High Desert and give you a straight answer about what is going on and what it will take to fix it — from a family-owned business that does not run on commission.

What We Offer:

Hidden Leak Detection – We identify the source of leaks that are not visible — inside walls, under floors, beneath slabs, and in crawl spaces — without unnecessary demolition or guesswork.
Supply Line Leak Repair – Cracked or failing supply lines are repaired or replaced fully, not patched over. We make sure the fix holds long-term and does not leave you with the same problem in six months.
Slab Leak Assessment – Slab leaks are serious and need to be handled carefully. We assess the situation, locate the source, and walk you through the repair options before any work begins.
Pipe Joint & Fitting Repair – Joints and fittings are common leak points in older homes, especially those that have gone through years of temperature cycling. We repair or replace compromised fittings and test the line before we leave.
Pinhole Leak Repair – Pinhole leaks in copper pipe are a common issue in High Desert homes due to hard water corrosion. We locate them and repair the affected section properly.
Water Meter Leak Check – If your meter is running when all fixtures are off, we trace the line and identify where the loss is occurring — whether inside the home or between the meter and the house.
Post-Repair Pressure Testing – After any leak repair, we test the line under pressure to confirm the fix is solid before closing anything up or considering the job complete.

Why Choose Smith Plumbing for Leak Detection & Pipe Repair

Accurate Location Before Any Demo – We identify where the leak is before recommending how to access it. That means less unnecessary opening of walls or floors and a more targeted repair from the start.
High Desert Pipe Conditions Experience – Temperature extremes in the High Desert cause accelerated wear on pipe joints, fittings, and copper lines. We know what to look for in homes that have gone through years of those conditions and diagnose accordingly.
Honest Assessment of Repair vs. Repipe – If a section of pipe has multiple failure points, we tell you that plainly rather than patching one leak at a time. You get a clear picture of what your home's plumbing actually needs.
No Commission on Recommendations – Whether the job is a minor supply line repair or something more involved, our recommendation is based on what the situation requires — not on what generates a bigger invoice for us.
Family-Owned & Locally Based – Smith Plumbing is based in Hesperia and serves the High Desert directly. We are not a franchise or a regional company dispatching from elsewhere — we work in these homes regularly and know the plumbing conditions in this area well.
