I moved my cleaning contract to Serna Services in September 2012 after continually poor service from a franchised cleaning company. The difference between the two was immediately clear.
The high level of cleaning and service is the same today as it was on day one. So often with cleaning companies you receive excellent initial levels of service that quickly drop off, this is not the case with Serna Services. Communication is excellent and frequent. If ever I need anything extra completed it is done so immediately without fuss. On the one occasion something was missed (and it was extremely minor!) it was followed up straight away and rectified.
As a customer you immediately get the sense that Serna Services is clearly a family run business that is big on scaled and far more professional than their rivals. The combination of these two elements proves to be very reassuring.
