Window Cleaning FAQs
Do you clean both the inside and outside of windows?
Yes. We can clean exterior glass, interior glass, or both. Tell us what you need when requesting your quote so we can plan the right amount of time and access.
Do screens, sills, and tracks come with the service?
Service details can vary by property. We can include screens and accessible frames, sills, or tracks by request. We will clarify the scope before work begins.
How often should Long Island windows be cleaned?
Many homeowners choose spring and fall service, while storefronts and high-traffic properties may need more frequent visits. Exposure to trees, sprinklers, traffic, and coastal air also affects timing.
Can you remove hard-water spots?
Many water spots improve with professional cleaning, but deeply etched mineral damage may require restoration beyond a standard visit. We will set realistic expectations after seeing the glass.
Do I need to be home?
For exterior-only service, often not, as long as we have safe access and any gates are unlocked. Interior cleaning requires access to the property.
Do you clean commercial windows?
Yes. We clean accessible storefront, office, and commercial glass and can discuss recurring maintenance for businesses.
