Easter Fence will be happy to contact the Missouri One Call service to mark the lines in the yard prior to fence installation. The Missouri One Call System will mark underground public utility lines such as electric, phone, water, and gas lines. The Missouri One Call does not mark private lines such as sprinkler systems, invisible fences, gas grill lines, or other customer-installed underground systems. Customers should inform the estimator and/or the installers of any other underground lines.
