Contacted 4 Hands Corp. to obtain an estimate for a retaining wall. Gerson De Oliveira contacted me immediately to arrange date/time to take a look at the project. I was very impressed with Gerson’s knowledge and professionalism. Gerson arranged for his staff, Joaquin & Carlos to the project. They were on time, professional and the end result turned out beautiful! Great job. I highly recommend Four Hands Corp.
