We use EPA-approved environmentally friendly commercial and industrial-grade cleaning solutions that are guaranteed to get you that long-lasting streak-free shine that you want for your office windows. Combined with our professional techniques and state-of-the-art equipment, there’s no beating our office window cleaning services in the GTA. Starting from the top and working our way down, we apply the cleaning solution directly onto the glass using a mop and then use a long squeegee to remove the soap suds with expert precision and attention to detail.
