What We Do
Leaks We Find & Fix
Leaks come from many sources. We diagnose and repair them all.
Pinhole Leaks
Pinhole leaks in copper pipes are common in O'ahu homes due to Hawaii's mineral-rich water. We locate every pinhole, not just the one causing immediate damage, and repair or replace the affected section.
Hidden Leaks Behind Walls & Ceilings
Discoloration, soft drywall, or musty smell are signs of a hidden leak. We use pressure testing and electronic detection to find it without tearing out entire walls.
Slab Leaks
Leaks under concrete slabs are serious and expensive to ignore. We locate slab leaks precisely and give you repair options — from spot repair through the slab to rerouting the line through the walls.
Pipe Joint & Fitting Leaks
Corroded or failed fittings, loose connections, and deteriorated pipe joints are repaired or replaced to restore a watertight system.
Water Heater Leaks
Water heater tank leaks, valve drips, and connection failures are diagnosed and repaired — or we'll advise you if replacement is the smarter investment.
Commercial Leak Repair
Leaks in commercial buildings, multi-unit properties, and restaurants require fast response to prevent business disruption. We handle commercial plumbing leaks across all of O'ahu.

Common Questions
Frequently Asked Questions
How do I know if I have a hidden leak?
The most reliable test: turn off all water in the house and check your water meter. If the meter is still moving, water is escaping somewhere. Other signs include a higher-than-usual bill, unexplained mold or moisture, and the sound of running water when nothing is on.
Can you find a leak without cutting into my walls?
In many cases, yes. We use pressure testing to isolate which section is leaking, and electronic detection equipment to pinpoint the location. We only open walls where the leak actually is — not a random fishing expedition.
What's a slab leak and why is it serious?
A slab leak is a leak in a water supply or drain line running under your concrete foundation. Left unchecked, it erodes the soil under the slab, can cause foundation movement, and promotes mold growth. It also wastes enormous amounts of water. Early detection and repair is critical.
Should I repair the leak or repipe?
It depends on the age and condition of your pipes. A single isolated leak on otherwise sound pipe can be repaired. If you have recurring leaks, widespread corrosion, or galvanized or polybutylene pipe, repiping is often the more cost-effective long-term solution. We'll give you an honest assessment.
