When a house is in such a bad mess that you are well aware that cleaning it by yourself might take a decade or more, then the services of cleaning crews would definitely come in handy. If there are people you know that are already using these clean crews, you can have them recommend them to you.
Sometimes the problem is not that you are not being able to clean your own house but instead because to plainly putting it, you are lazy. When this is the case, hire cleaning crews on a part time basis. They do not need to come to your house every other day. Have them at your house when it is most suitable for you. An option of having them even once a year is also one to consider.
If you choose to have them come once a year, then you can ignore cleaning at all until that day that when they will. This is for people who find cleaning a little too much for them to handle.
Get to enjoy the effects of having a clean house and after the cleaning crews are done with their work. Despite that e can let the dirt get out of hand sometimes, deep down we enjoy being in a clean sweet smelling house. For the better part it is hassle free and you get to have peace of mind where having a clean house is concerned. This way you can concentrate on any other part of your life like your job.
