Elek did such a nice job the last time I had Derrick come back to install a RO water filter for the kitchen. Again he was on time, very professional, skilled and didn't fluster. The job was done efficiently quickly. Derrick found a small leak in the kitchen drain. Mo problem, easily fixed. I highly recommend Elek and kudos to Derrick. No I am not related to any of them. I simply appreciate a job very well done.
