To understand why certain cleaning companies subcontract services to individual house cleaners or other companies, you must first understand how much time and resources it takes to run a full-service cleaning company. Investing in quality equipment and cleaning supplies, training house cleaners, acquiring insurance, paying taxes, and so forth are all examples of overhead costs.
On the flip side, when a cleaning company uses subcontractors, they cannot be held directly accountable for bad service, or are liable in the event of injury and/or theft. In fact, the business serves only as an advertiser, with the subcontractor doing all of the work. Clients that are unaware that a third party has been hired to clean their home run a risk of dealing with incompetent and unregistered house cleaners. That being said, if the company can confirm that the subcontractors are properly trained, insured, trustworthy, and so on, one can feel confident in hiring them.
Lastly don’t let the “bad” ones deter you from finding a great house cleaning service. All you have to do is avoid maid services with major red flags and give the green light to a respectable and trusted cleaning company!
