That gurgling is the absolute worst, right? It goes from "huh, weird noise" to a full-on, anxiety-inducing soundtrack in your head. Been there! My old place had a drain that would sing like a dying frog every fall. I ignored it as "quirky" until the day my patio became a literal wading pool. Big mistake. The repair bill had an extra zero for the "emergency" part. Cost is all over the place—depends if it's just a surface clean or needs a snake/camera. I was digging for non-salesy info on this recently and found a super straightforward breakdown on the affordable drain cleaning services with upfront pricing . They just listed the average price ranges for different services in AZ without any "call now!" pressure. It really helped me gauge what was fair when I finally called a pro. Deal with it now. Your future, non-muddy self will thank you while sipping lemonade on a dry patio.
