Some years ago we had Northlake Fence install a sliding car gate for our trucks. Northlake has since gone out of business as far as I can tell. From the start, each time it was operated, the gate impacted the first two fence posts. Northlake refused to help and treated us like we were trying to cheat them. The owner said "the ground shifted." Northlake also provided a loud, inferior Patriot opener that has broken down about 10 times. After the last break down, we called in Mario, owner of Gate Service LLC. He took one look and said, "They put the track too close." So we had Mario put it all to rights. He moved the track and installed a quiet, more powerful, more sophisticated, and more sturdy Liftmaster opener that works GREAT. Finally the gate operates smoothly the way it is supposed to and we aren't stressing every single time we press the button wondering, "Is it going to work?" We are very happy to have found Mario. He's a straight-talking, trustworthy, hard working guy who does things right. And his prices are fair. If you need a sliding gate opener, or need yours fixed, I recommend him.
