Why Fast Action Matters

A pinhole leak loses up to 10,000 gallons per year. Beyond the water bill, persistent moisture causes mold that can cost tens of thousands to remediate. Early detection saves money and your home.

Leak Detection & Repair FAQ

Common Questions
Answered.

How do you find a leak without opening walls?
We use acoustic leak detection (listening devices), thermal imaging, and pressure testing to pinpoint leaks with minimal or no wall opening required.
My water bill spiked but I can't see a leak. What's happening?
Most likely a hidden leak inside a wall, under a slab, or in a supply line. These are the most damaging because they go undetected. Call us for an inspection.
Do you repair the leak or just find it?
Both. We locate AND repair the leak in the same visit whenever possible. You won't need a separate contractor.
Can leaks cause mold in NYC apartments?
Yes — even a slow drip behind a wall creates the moisture mold needs. In NYC's tightly constructed apartments and co-ops, mold spreads quickly. Address leaks fast.
