The water bill jumped. You can't figure out why.

Or the warm spot showed up on the floor. The damp patch in the closet. The mildew smell that wasn't there last month. The sound of running water with everything off.

You're not paranoid. Something is leaking. The only question is where — and how much damage it's doing while you try to figure it out.

Most plumbers respond to leaks. We specialize in finding them. The distinction matters because hidden leaks in St. James homes cause damage on a clock, and every day of delay multiplies what the eventual repair will cost.

What Hidden Leaks Cost When You Wait

A week of delay on a visible leak costs you almost nothing. A week of delay on a hidden leak costs far more than you'd guess.

Water saturates materials. Subfloor swells. Drywall wicks moisture. Mold begins. Structural damage follows. Insurance complications arise. The detection visit that catches the leak early prevents almost all of that.

From the Blog: The Single Biggest Reason Hidden Leaks Get Missed
