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.

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