The cost of a professional deep clean ranges from $180 to $375, depending on the size of the home and what state it’s in. A 2,000-square-foot home, for example, can cost anywhere from $240 to $500 to deep clean, while a 3,000-square-foot home falls in the $360 to $750 range. 

No, house cleaners or cleaning services do not need to be certified or licensed. Each state has its own requirements for licensing and certifications for companies, but most states don't require any special training to clean a home. Be sure to check our state licensing tool to review the local guidelines for house cleaners and cleaning services.

Putting off cleaning your fridge is a bad idea for a few reasons. For one, any food spills can build up, making it much harder to clean your fridge when you finally do get around to it. Plus, any stray pickle juice or leaky leftovers are a recipe for a stinky fridge. 

But beyond that, if you don’t clean your fridge, it could be a health hazard. Old food can turn moldy and old spills can too. Even if none of that scares you, putting off cleaning your fridge will make it look downright gross, which should be reason enough to break out your sponge. 

Before hiring a cleaning service for your home, it's wise to ask several questions. Find out what services they offer, whether they work alone or with a company, and if they can provide references. It's also important to ask if they conduct background checks on employees. Inquire about their scheduling, availability, and when they can provide an estimate. Confirm if they have insurance, offer a guarantee, and bring their own cleaning supplies and equipment. You should also clarify if you need to be home during the cleaning, what arrangements are necessary for pets, and if there is a written contract. Finally, ask how they set their rates and if they are available for emergencies and what those charges would be.
