- JAJames AguilaApr 27, 20265.0Not every job goes to plan. Sometimes things go wrong. Sometimes they are our own fault, sometimes they are not. I called GLS to come snake my drains and found my entire basement sewer system was collapsed. Not everything went smoothly, but Nick and Joe made sure that everything came out correctly in the end. I think the biggest reason for my 5 star review is that when there were issues, they fixed it. No excuses. No argument. They just made it better. I recommend GLS. I would use them again.
