Gold Medal Services, LLC, warrants and guarantees to the original purchaser, that should Customer accept and purchase Gold Medal's recommended repair, such repair shall be free from defect in materials and workmanship under normal use and conditions for as long as the Customer owns the residence in which the recommended repair was provided or until the Unit in which the Covered Repair was performed, if applicable, is replaced.

"Gold Medal really helped out after our sewer line backed up into our basement. The other pros all wanted us to pay for a camera view first for several hundred. Then the actual cleaning of the line was $500 and up depending on the results of the camera. Gold Medal had a fixed price for cleaning out a sewer line. They came and quickly diagnosed the problem and cleaned it out. Our technician Brett was awesome and even put us in touch with DryTech to assist cleaning up the water damage."
