We hired Andy's Heal and Seal to repair our interlock walkway and patio during June, 2016. His crew arrived promptly and completed the work over 3 days. What appeared to be a job well done changed 3 weeks after when weeds started appearing all over our patio. Once I called, we were assured Andy would come by within a week and a half to redo the affected areas. After all, he advertises 1 year warranty on his work. After 4 weeks of no show, I called again. Once again, we were told he would come by the following week. Called again, after 2 weeks, when no one showed up and my calls are no longer being answered. After almost 2 months of waiting, It appears he has no interest in returning to correct his work. We have resorted to hiring another company to fix Andy's work.
