Window Cleaning in Sterling — Common Questions

Do you clean interior glass too, or only the exterior?

This service covers exterior window, screen, and track cleaning. If you want interior glass addressed at the same visit, tell us when you call (703) 650-5655 and we'll confirm whether it fits the scope of your appointment. Our crews work Sterling regularly, so scheduling is usually available within the week outside the spring rush — and every visit ends with before-and-after photos of the finished work.

Will you actually remove hard-water spots, or just wash around them?

We treat hard-water and mineral deposits as a distinct step from general glass washing. Loudoun's water carries enough calcium and magnesium that a standard rinse won't touch etched spotting, so we address it directly on affected panes and sills. Our crews work Sterling regularly, so scheduling is usually available within the week outside the spring rush — and every visit ends with before-and-after photos of the finished work.

My house backs to trees in Cascades and gets constant sap and pollen. Can you keep up with that?

Yes. Sap and pollen buildup near wooded lots is one of the most common conditions we see in Sterling, and it's exactly why we recommend a seasonal cadence rather than a one-time clean for tree-heavy properties. Our crews work Sterling regularly, so scheduling is usually available within the week outside the spring rush — and every visit ends with before-and-after photos of the finished work.

Do you clean the screens and tracks, or just the glass?

Screens and tracks are part of this service. Grit and pollen that collect in tracks are often what causes frames to look dirty even after the glass itself is clean, so we address both. Our crews work Sterling regularly, so scheduling is usually available within the week outside the spring rush — and every visit ends with before-and-after photos of the finished work.

How do you handle townhomes where windows are close to a neighbor's yard or sprinklers?

We account for overspray and shared drainage patterns common in Countryside and Potomac Falls townhome clusters, and we work carefully around adjacent landscaping and property lines. Our crews work Sterling regularly, so scheduling is usually available within the week outside the spring rush — and every visit ends with before-and-after photos of the finished work.

How do I get a quote for my property in Sterling?

Call (703) 650-5655 and describe your home's size, window count, and any specific problem areas like sap or hard-water spotting. We'll get you a straightforward quote, no pressure. Our crews work Sterling regularly, so scheduling is usually available within the week outside the spring rush — and every visit ends with before-and-after photos of the finished work.

How much does exterior window cleaning cost in Northern Virginia?

Most homes land at $8–$15 per exterior window including screens and sills — a typical 25-window colonial runs $200–$375. Bundling with house washing saves on both. Quotes are written and line-item. Palladians, transoms, and true divided-light windows quote a touch higher for the detail time — the walkthrough counts every pane so the quote is exact. Serving Sterling and all of Loudoun County.
