Replacing pipes is 50% to 75% more expensive than lining them. Lining is a non-invasive process. There is no destruction to buildings or landscape. Reconstruction costs for repiping can be 60% of direct pipe repair costs and epoxy lining eliminates the need for reconstruction. Over time, up to 75% of the original flow capacity can be lost as result of corrosion leading to much higher energy bills. Restoring those pipes reduces energy costs.
