Premier Window Cleaning for Ontario’s Homes and Businesses

From the historic estates along the Euclid Avenue corridor to the modern, energy-efficient neighborhoods of Ontario Ranch, Sunshine Windows has been a staple of the Ontario community since 1978. We know that living in a major Inland Empire hub like Ontario means your windows face a constant onslaught of dust and grime from the airport vicinity, freeway dust from the 10 and 60 corridors, and the heavy seasonal pollen from our local parks. Our team specializes in restoring the clarity and curb appeal of your property, whether it’s a classic mid-century home or a high-traffic commercial storefront near the Ontario Mills area. We offer more than just a quick rinse—we provide deep track cleaning, screen detailing, and hard water removal tailored to Ontario’s unique environment. Experience the 'Way Better' difference from a local team that treats every Ontario property with hometown pride.
