Licensed, bonded, and insured, the highly trained cleaners of Karen’s Kleaning oust the filth that occupies homes with a litany of housecleaning services. Whether residents call upon one cleaner for two hours or two cleaners for one hour, Karen's techs spruce up interiors with Green Seal–certified cleaning products that have lower environmental impact than chemical sprays or coal-lump Brillo Pads. The basic cleaning services range from mopping and vacuuming the floors and ceilings to dusting the furniture and wiping down kitchens and bathrooms. Karen's Kleaning guarantees the work of its grime fighters, and will return to finish the job if a client is not satisfied or if a newly waxed countertop begins to outshine tinfoil silhouettes of Julia Child. Homeowners can hire the cleaners for more than two hours for $33 per hour per cleaner.
