FAQs

Will the rain ruin my window cleaning?
Not at all! Freshly cleaned windows actually hold up well in the rain. Rainwater itself is typically clean—what makes windows look bad is the dirt already on them. Plus, we offer a 48 hours Rain Guarantee: if it rains within a week of your service and you notice any spots, we’ll come back and touch them up for free.

How do you clean the windows?
We use two highly effective methods, depending on the job:

  • Traditional hand cleaning with a scrubber and squeegee.

  • Purified water system using a soft brush and mineral-free water for a streak-free shine.
    No high pressure, no harsh chemicals—just a careful, thorough process that’s safe for your glass and frames.

How often should I clean my windows?
We recommend cleaning your windows every 6 to 12 months. If you prefer more frequent service, we offer discounted rates for bi-monthly, quarterly, or custom cleaning plans.

How do I pay?
We make payment easy! You can pay by:
✔️ Credit or debit card (Note fee is applied
