We highly recommend the Greener Portland Cleaning Co. Our law firm relocated to Westbrook from Portland and amongst many important tasks was finding a reliable & affordable office cleaning service. The team come in after hours and on the weekend so as not to disturb us during office hours, and are always happy to oblige if we have to change the schedule or make a special request. The office always looks pristine and smells great, not of chemicals, since they use environmentally friendly products.
