Very Disappointed, On an existing driveway power washing , replace polymeric Sand and seal the first day the driveway looked amazing did not stay like this , in couple days the sealant was missing In many area of the stones . On the new section of the driveway that they did half of the stones are white same problem the sealant not there . Came back did second coat , again the same problem and getting worst now the polymeric sand is loose between stone and cracking job was done 2 months plus . Nothing but problems, many excuses weather too hot drive way dirty etc. Last communication July 9 Carlos said next week no show send messages no answer. I just need the job to done right , would I recommend this company NO unless they right all the problems permanently and not a quick fix . UPDATE: Carlos has communicated with me and has stared to fix the problems , and has assured me that it would look and stay the same way as the first day that the did job was done . He was prompt and to his word on time and day.
