Does dredging toilets belong to the scope of property services?

Your question didn't say whether it was the property service of public buildings or the property service of residential quarters. According to industry practice, toilet dredging in residential areas does not belong to the scope of property services. Generally speaking, the scope of property services does not include the area within the owner's entrance door, but if the property service contract signed between the owner and the property company includes toilet dredging service, the property company must dredge it.
