Living on Costa Rica's South Pacific coast is beautiful — and hard on your glass. Ocean salt spray leaves a hazy film on windows within weeks, tropical humidity encourages mold and mildew around frames, and heavy seasonal rains carry dust and pollen that dry into stubborn water spots. Homes and vacation rentals in Uvita, Dominical, Ojochal and the surrounding Ballena Coast communities face all of this at once, which is why professional window cleaning is essential maintenance here rather than a luxury.
OSA Windows Cleaning is a locally owned company that specializes in keeping coastal homes, Airbnb rentals, restaurants and commercial buildings looking their best. We use purified water systems and water-fed poles that reach tall tropical glass safely from the ground, traditional squeegee techniques for a hand-finished streak free interior clean, and gentle, non-abrasive methods for solar panels so your system keeps producing at its full capacity. Every job is covered by our streak-free guarantee: if you are not happy with the result, we come back and make it right.
One-time reset for vacation rentals and commercial spaces: interior and exterior windows, glass railings and mirrors brought back to streak-free condition, with ongoing maintenance schedules available for hosts.
Full exterior window cleaning using a purified-water fed pole system that reaches up to three stories from the ground. Salt film, dust, pollen and water spots are rinsed away with deionized water, so glass dries spotless without chemicals or ladders.
Traditional hand-finished interior cleaning with professional squeegees, including window tracks, sills and frames. We work carefully around your furniture and floors, and every pane is inspected under natural light before we pack up.
Gentle, non-abrasive cleaning of rooftop solar panels to remove the dry-season dust, pollen and bird droppings that reduce energy output. Soft brushes and purified water protect the anti-reflective coating while restoring maximum light transmission.
For properties within a few hundred meters of the beach in Dominical or Uvita, we recommend an exterior window cleaning every two to three months to stay ahead of salt buildup. Inland homes around Ojochal and the coastal ridge typically do well with a cleaning every four to six months. Vacation rentals and hotels should clean interiors between guest stays or monthly, and solar panels perform best when cleaned at least once at the end of the dry season — dust and pollen from December through April can cut panel output noticeably. Regular cleaning also protects your investment by preventing permanent mineral etching on glass and corrosion on frames.
