Why Greencap Cleaning for Window Cleaning
Why Buildings Switch Window Cleaners
Window cleaning is easy to do badly, and the results show the next sunny day. Property managers usually call us after:
- Streaks, film, and drips left after the last visit
- Missed upper floors or skipped interior glass
- No-shows and unreliable scheduling
- Crews without proper insurance for building access
- Frames and sills ignored so dirt washes back down
Greencap Cleaning uses purified-water systems and insured crews to deliver a consistent, streak-free finish on every visit.

Frequently Asked Questions (FAQs)
How often should commercial windows be cleaned?
Most storefronts benefit from monthly cleaning, while offices often choose quarterly. High-traffic or street-level glass in NYC may need more frequent visits, and we recommend a cadence after reviewing your property.
Why do my windows streak after cleaning?
Streaks usually come from soap residue or dirty water drying on the glass. Our purified-water method rinses clean and dries spot-free, so no film is left behind.
Do you clean storefront glass during business hours?
Yes. Storefront cleaning is quick, and we can work before you open or during quiet periods so customers are never blocked.
Do you wipe frames, sills, and tracks too?
Yes, on every visit. Leaving them dirty lets grime wash back onto clean glass after the next rain, so they are part of the job.
Do you offer recurring window cleaning contracts?
Yes. Most commercial clients set a weekly, monthly, or quarterly schedule so their glass stays consistently clear year round.
Do you clean both the inside and outside of windows?
Yes. We clean interior and exterior glass along with frames, sills, and tracks, so the whole window looks finished rather than just one side.
Can you reach high or hard-to-access windows?
We match the access method to your building height using pole-fed purified-water systems and appropriate equipment, and we assess the safest approach for tall facades during the site review.
Will cleaning disrupt my business hours?
No. We schedule before opening or after hours so retail and office operations continue uninterrupted.
Are you licensed and insured?
Yes. Greencap Cleaning is licensed and insured, and our crews are experienced with five-borough commercial building access.
