Window Cleaning in Great Falls, Virginia

That's hard water and mineral residue, not dirt. Fairfax Water runs moderately hard through Great Falls, roughly 7-9 grains per gallon of calcium and magnesium. When rain or sprinkler overspray dries on the glass, it leaves that mineral film behind, and on south- and west-facing panes it bakes on in the sun. We treat it as a hard-water job, not a standard wash, so it actually lifts instead of smearing around.

Both, every visit. Great Falls' wooded lots mean pollen and fine debris settle directly into screen mesh and window tracks, not just on the pane. We pull screens and rinse them separately, and we clear tracks so sashes seat and seal properly again. Glass-only cleaning that skips screens and tracks just leaves the source of the next round of grime in place.

Yes, but it needs the right approach. Hardened tree sap on glass won't come off with soap and water alone. We use a safe, glass-appropriate method to break down the sap without scratching the surface, then finish with a full squeegee pass so no residue is left to re-attract dust and pollen.

Most estate-scale homes here do well with two service visits a year, timed around the spring pollen drop and the fall leaf and sap season. Properties heavy with mature tree canopy or close to irrigated lawns sometimes benefit from a third visit mid-summer when mineral buildup from sprinklers is heaviest.

Yes. Great Falls' larger custom homes commonly include skylights, sunrooms, and multi-story glass that standard equipment can't safely reach. We come equipped for that scale of property and inspect every pane, high or low, rather than servicing only what's reachable from the ground. Our crews work Great Falls 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.

We offer both. Many Great Falls clients book exterior-only service to handle pollen, sap, and hard-water spotting from the outside, and add interior cleaning for full-glass rooms like sunrooms where both sides show. Tell us the scope when you call and we'll size the job to the property.

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 Great Falls and all of Fairfax County.
