Why Leak Detection Matters

Even small leaks can lead to big problems over time. Detecting them early can save you thousands in repair costs, damage, and wasted water. Here’s why leak detection is crucial:

  • Prevent structural damage – Leaks in walls, floors, or foundations can weaken building materials.

  • Stop mold and mildew growth – Moisture encourages mold, which impacts health and indoor air quality.

  • Save water & reduce bills – Hidden leaks waste water and drive up your utility costs.

  • Protect your finishes & possessions – Don’t risk ruined flooring, cabinetry, drywall, or personal items.

  • Avoid large repairs later – Catching leaks early means less invasive, more affordable fixes.

Our Leak Detection & Repair Approach

At PC Home Services, we combine experience + advanced tools to deliver precision leak detection with minimal disruption.

Here’s how we do it:

  1. Initial inspection & assessment
    We start by observing visible signs (damp walls, water stains, odd water bills) and asking about recent plumbing issues.

  2. Non-invasive diagnostic techniques
    Using state-of-the-art tools, we can pinpoint leaks without tearing out walls or floors. Methods include:

    • Acoustic listening / sound amplification

    • Thermal imaging / infrared scanning

    • Moisture meters & humidity sensors

    • Video camera pipe inspections

    • Tracer gas or pressure testing (for hidden pipe leaks)

  3. Precise localization
    Once we detect a leak, we pinpoint the exact pipe, joint, or section responsible. This allows us to target the repair.

  4. Repair or remediation
    Our licensed plumbers select the most appropriate solution — from patch repairs to pipe replacement or re-routing. We aim for lasting fixes.

  5. Verification & quality check
    After repair, we re-test to confirm there are no hidden leaks and ensure full system integrity.

  6. Cleanup & restoration
    If any minor cutting was needed, we restore finishes to make repairs as invisible as possible.

Types of Leaks We Locate & Repair

We handle a wide range of leak types in residential and commercial settings across San Jose:

  • Slab leaks (under concrete foundation)

  • Wall or ceiling leaks

  • Underground service-line leaks

  • Water supply line leaks (to fixtures, appliances)

  • Irrigation / sprinkler leaks

  • Pool, spa, or fountain leaks

  • Leaks in pipe joints, fittings, valves

Costs vary depending on the location and complexity, but we provide upfront estimates and pocket-friendly inspection options.

Many leaks can be located in under an hour using non-invasive methods. More complex cases (e.g. slab leaks under concrete) may take longer.

We always aim for non-destructive methods. Only if absolutely needed do we cut small access points — and we restore them cleanly.
