It started a few months ago, but lately I’ve been unable to ignore the smell coming from my bathroom drain. I don’t understand how, but it smells so moldy. Obviously I need someone to come out, but a plumber seems unnecessary. I’m looking for Drain Cleaning Dallas companies who can just give it a good clean and get rid of the mold. I suppose a plumber could identify any area where water is leaking or building up, though, so maybe I need one, too.
