Keeping an environmentally friendly home is the first step toward becoming eco-conscious, and the last step is tending to a car-top garden and taping leaves back on trees.

Avanti Green’s cleaners scour and scrub home interiors with an arsenal of nontoxic cleansers and biodegradable products certified by the Green Clean Institute. For 1.5 hours, two banishers of besmirchment will purify sink areas, empty trash bins, and sweep floors in the kitchen; disinfect showers, sinks, and countertops in the bathroom; and outwit trolls standing guard at the entrance of the laundry room. Technicians will also polish fixtures, dust furniture, and mop floors before clearing away cobwebs and changing bed linens if owners decide to leave a fresh set out. Customers may provide a priority list to help direct the Avanti team to preferred areas, such as dirt-stricken floors, windows, or cellars housing collections of vintage parking tickets.

All services are performed with nontoxic cleaning products free of petroleum distillates, chlorines, or soapy porcupines, ensuring a safe environment for pets, children, and guests. Peruse the Avanti Green website for a complete list of services.
