About OSA Windows Cleaning

OSA Windows Cleaning is a professional window cleaning company serving homes and businesses across Costa Rica. We specialize in residential and commercial window cleaning, high-rise and hard-to-reach glass, solar panel cleaning, and screen and track cleaning. Whether you own a single-story home, a beachfront condo, or a multi-story office building, our team delivers spotless, streak-free results using modern water-fed pole systems and proven squeegee techniques.

Our service is built for property owners who care about their views. Tropical weather, salt air, and dust from the dry season coat glass and solar panels quickly — dirty windows dim your home, and dirty panels can cost you energy output every day. That is why homeowners, Airbnb hosts, property managers, and business owners across the region rely on us for recurring and one-time cleanings backed by our streak-free guarantee.

OSA Windows Cleaning is a locally owned and operated business. Every job is handled by our own trained, insured crew — no subcontractors, no shortcuts. We show up on time, protect your floors and furniture while we work, and leave your glass clearer than the day it was installed. With a five-star rating from our clients and hundreds of windows cleaned, we are proud to be the team our neighbors call for brighter views.
