I contacted Rolando Cristobal of Cristobal Concrete Construction for an estimate for providing concrete along the side of my house. the estimate was acceptable. Rolando and his crew started work on that Tuesday and completed the job on Friday of the same week. He and his crew provided outstanding quality and support. Rolando cleared the area reconfigured the Irrigation and drainage, leveled, framed and prepared the area, completed the concrete work perfectly. I would recommend Cristobal Concrete Construction to anyone looking for an extremely impressive concrete job, on time and cost-effective professional team.
