My wife and I originally started working with System Pavers five years ago when we had 2100 square feet of pavers placed in our garden as a path throughout the garden. After five years my wife thought it was time to have the pavers pressure washed and cleaned. We also had Polymeric sand put in to replace the old sand as the old sand did not prevent weeds from growing through. We worked with Project Manager Lester Yue from start to finish on this job and we were very pleased with the superb customer service he provided to us. I would highly recommend System Pavers and would continue to use them in the future. Their workers do an excellent job.
