Why Dar Window Cleaning?

Crystal-Clear Windows, Every Single Time

Dirty windows don't just look bad — they block natural light, reduce curb appeal, and can permanently etch glass with hard water minerals and acid rain over time. Our professional team uses a purified water fed-pole system combined with traditional squeegee techniques for flawless, streak-free results on every home and business we service across the GTA.

  • Interior & exterior cleaning — we handle both sides so you don't have to
  • Purified water system — 100% pure, leaves zero residue or spotting
  • Hard water stain removal — specialist treatment for stubborn mineral deposits
  • Screen cleaning included — frames, sills, and tracks wiped down
  • Fully insured — commercial liability coverage, WSIB-compliant
  • Satisfaction guarantee — we re-clean anything you're not happy with

Common Questions

Window Cleaning FAQs

How often should I have my windows cleaned?
For most GTA homeowners, we recommend 2–4 times per year: spring (after winter road salt and grime), summer (pollen and insects), fall (before leaves stick to glass), and a mid-year clean if needed. Commercial properties benefit from monthly service. Regular cleaning also prevents hard water minerals and acid rain from permanently etching the glass.
Do you clean interior windows too?
Yes — we offer both interior and exterior cleaning together or separately. Interior cleans require someone to be home to grant access. Just let us know when you book and we'll accommodate your preference.
What if it rains right after my windows are cleaned?
Rain water is actually clean and will not leave streaks on its own. Streaks come from dust and soap residue, not water. Because we use a 100% purified water system with no soaps or chemicals, rain will simply rinse off clean. You don't need to reschedule around the weather.
How do you price residential window cleaning?
Pricing is based on the number and size of windows, the number of storeys, and whether you want interior, exterior, or both. A typical 2-storey home with 20 windows costs between $150–$250. We always provide a free, transparent quote before we start — no surprises, no hidden fees.
Can you remove hard water stains from glass?
Yes. Hard water (mineral) stains are one of our specialties. We use professional-grade mineral deposit removers and polishing compounds to restore glass clarity. Some very old or deep-etched staining may not be 100% reversible, but we'll give you an honest assessment in advance.
Are you insured to work on my property?
Absolutely. Dar Window Cleaning carries full commercial liability insurance. You're protected against any accidental property damage. We're also WSIB-compliant for worker safety.
Do you offer recurring window cleaning plans?
Yes! We offer seasonal packages (spring + fall), quarterly (4×/year), and monthly plans for commercial clients. Recurring customers get priority scheduling and discounted rates. Ask about our maintenance packages when you book.
What areas in the GTA do you cover?
We cover the entire Greater Toronto Area including Toronto, Mississauga, Brampton, Vaughan, Markham, Richmond Hill, Oakville, Burlington, Ajax, Pickering, Scarborough, North York, Etobicoke, Newmarket, Aurora, Whitby, and surrounding communities.
