COMMERCIAL WINDOW CLEANING

Bringing clarity and curb appeal to your property with professional corporate window cleaning.

Window Cleaning For Businesses

Commercial window cleaning keeps your premises looking professional while protecting your building’s materials over time. Clean windows allow more natural light in, create a better working environment, and leave a positive impression on staff, visitors, and clients. When left untreated, dirt and grime can lead to staining, reduce visibility, and even contribute to long-term damage.

At Neptune Cleaning, we provide commercial window cleaning across Hampshire and Southampton for a wide range of sectors, including offices, schools, retail, hospitality, and industrial sites. From one-off cleans to regular contracts, our experienced team delivers consistent, high-quality results, even on buildings with complex access needs.

We’re also experienced in working with businesses through formal tender processes and can provide supporting documentation and mobilisation as needed. For those seeking a complete solution, we offer additional exterior cleaning services to help streamline building maintenance under one reliable provider.
