Upon my water company alerting us that our service showed significant additional water consumption I called several water locators. After failing to get responses from several companies I contacted ALD who were quick to respond and located the leak at an exterior irrigation valve box. The leak was repaired and a copy of ALD's report were submitted to the water company as proof that the leak was addressed. Also ALD's estimate of the water loss was spot on with what the water company said they were showing.
