How We Clean

Professional Equipment & Techniques

Our technicians use the same tools and methods trusted by the world's leading commercial cleaning companies.

🧹

Professional Squeegees

Commercial-grade brass and stainless steel squeegees in multiple sizes for every window type. We use Ettore, Unger, and Moerman professional channels for a perfect, streak-free edge every time.

💧

Purified Water Systems

Our water-fed pole systems use deionized, purified water that leaves zero mineral deposits or water spots. The same technology used on skyscrapers and luxury properties worldwide.

🌿

Eco-Friendly Solutions

We use biodegradable, non-toxic cleaning solutions that are safe for your customers, employees, landscaping, and the environment. No harsh chemicals, no ammonia, no residue.

Safety First

Fully Insured, Safety-Certified Crews

Every technician in our network is background-checked, drug-screened, and trained to OSHA safety standards. For elevated work, our crews hold IWCA (International Window Cleaning Association) certifications and use fall-protection systems on every job.

We carry $2M+ in general liability insurance, full workers' compensation coverage, and commercial auto insurance. Certificates of insurance are available on request — often within the hour.

Your facilities team can rest easy knowing that every crew member on your property meets the highest professional standards in the industry.
