Commercial Window Cleaning
Clean glass is the cheapest advertising you have. Bright, streak-free windows pull people toward a storefront and make an office feel open and well run, while grimy glass sends the opposite message. 3Point Cleaning keeps your windows clear inside and out, on a one-time or recurring schedule. We clean, you shine.
Many clients add window cleaning to their regular janitorial plan so it is handled automatically and never forgotten.
What Our Window Cleaning Covers
We leave the whole opening clean, not just the glass:
- All interior glass, plus first-story exterior windows
- Second-story and higher windows that tilt or pop inward, cleaned safely from inside
- Sills, frames, and tracks wiped down
- Entry doors, glass partitions, and storefront windows
- Screens cleaned on request
- Scheduled or one-time service
The 3Point Difference
Every service comes with the 3Point standard:
- Local and responsive. Maine owned since 2012, with 24/7 dispatch and same-day support. You reach real people, not a call center.
- Bonded, insured, and vetted. Every cleaner passes reference and criminal background checks plus drug testing, and works uniformed and supervised.
- No long-term contracts. Simple flat-monthly or hourly billing, on a schedule that fits your business.
New accounts start with a walkthrough and an initial deep clean to set a consistent standard, then we keep it there. See our Proven Process.

Frequently Asked Questions
Do you clean both interior and exterior windows?
Yes. We clean all of your interior glass and first-story exterior windows, along with sills and frames, for a complete finish.
How often should commercial windows be cleaned?
Storefronts and entrances often look best with monthly cleaning, while many offices do well quarterly. We will suggest a schedule based on your location and foot traffic.
How high can you reach?
We do first-story exterior and all interior windows, or second-story and above windows if they are pop-out windows. We don’t go up on lifts, ladders, or poles.
Will the windows streak?
No. We use professional tools and techniques for a clean, streak-free result, even in Maine weather.
Can you work around our business hours?
Yes. We schedule window cleaning at times that keep your entrances and storefront clear during your busiest hours.
Do you clean windows in winter?
Yes, weather permitting. We monitor conditions and reschedule if temperatures or storms would affect the results or safety.
Are your cleaners insured and background-checked?
Yes. 3Point Cleaning is fully bonded and insured, and every employee passes reference and criminal background checks plus drug testing before entering a client facility. Our cleaners are uniformed, trained, and supervised.
