I never write reviews mostly because all the work I’ve had done here in miami has been subpar/incomplete or simply disorganized and unprofessional. I am elated to say that my experience with National Sealing Company has been excellent. I needed my huge brick fireplace to be “revived” prior to placing a TV. The brick was drab, dull and grayish –the catch–I needed it done within 24 hours because the TV installers were scheduled 2 days later.  Not only did Kenny rearrange his schedule to send me someone the next day (and in the evening which was better for me) but his worker Mark was OUTSTANDING.  The brick became a beautiful red orange color that it once was. Mark showed up on time. He made sure all my furniture was protected and was kind, courteous and professional. Further, I  showed him a problem that I had with my outdoor porcelain tile. He recognized the problem and gave me a tip to correct the problem.  ( Saving almost two thousand dollars that a tile contractor quoted me) all in all, I  couldn’t be more pleased.
