If things are really clogged up, it won’t be hard to notice. Slower than normal draining speeds and standing water are obvious signs that a blockage is building. But there are also some more subtle signs that may indicate it is time for a commercial drain cleaning appointment. For example, if you notice strange noises such as gurgling sounds coming from your drains, or even unpleasant smells emitting from the sink, you should contact Maintain It for an inspection as soon as possible. This is especially true if you notice water or puddles gathering outside near your building, which could indicate an even larger sewage line issue. As always, the earlier you catch it, the easier it will be to fix — and with regular preventative cleanings, these problems can be avoided altogether.
