Great question! If there is a come back on the area where our team worked and your guarantee certificate is valid, Richie will send a team out to assess and repair accordingly. There is no doubt we have had some comebacks in the past. There is no waterproofing contractor that has not had a comeback due to the nature of the work. However, we attend to comebacks quickly, effortlessly and with ZERO hesitation. That is one of the reasons why we stand out from the rest.
