As an excavating company we have our own locators to double check utility companies work, has saved our assess lots of times. Locators don't gaurentee anything and liability is on the excavator if you read the fine print. That being said if you're nice the utility companies often don't charge to come fix especially if you demonstrate that you did due diligence and hired a locate company. Your private locator is going to have all kind of unkind things to say behind your back if you ask him to fix it when you weren't even there to tell him what you wanted. We never even call in house service phone lines, we just fix them ourselves up to about 30 pair. Waterproof terminal kit is cheap. Even the utility company isn't usually more then a couple hundred.
