Have you used our service or another professional cleaning service within 30 days or less? Then, we recommend you start with a "regular" or "standard" cleaning. Meanwhile, have you not had a professional cleaning in over 3 months and can more than likely, spot some excessive grime or dirt buildup in certain corners of your home? Then, we recommend you select "heavy duty" cleaning add on when booking your "regular" residential cleaning services. This is to later, avoid extra fee's being added to your invoice upon arrival of your housemaid. For instance, has it been over six months and you are starting to see dust, cobwebs, or severely stained surfaces? Certainly, our professional deep cleaning services is highly recommended.
