Confirm the surfaces and protect the room. Do not use an unfamiliar cleaner on tinted, coated, or specialty glass.
Why clean both sides when needed?
Outdoor service cannot remove fingerprints or residue from the room-facing surface. Check from inside before assuming an exterior appointment has missed a mark. Some windows need both faces addressed; others need only a targeted visit.
Cleaning is not a remedy for persistent indoor moisture or hidden fogging. Record whether a mark can be reached on an exposed surface and whether it changes with time or weather.
How should you prepare the room?
Do not take apart a sash or lean through an opening to help. Follow product-specific instructions for any tilt-in or removable components.
- Remove small breakables from accessible sills and nearby furniture.
- Discuss heavy furniture or fitted shades rather than moving them unsafely yourself.
- Point out films, decorative glass, damaged finishes, and any known cleaning restrictions.
- Arrange access to the agreed rooms and keep pets out of the work area.
What belongs in the finish review?
Walk through the listed rooms and compare the agreed glass faces, frames, and sills with the quote. Explain whether a stubborn area was treated, left pending assessment, or excluded because access or material condition made cleaning inappropriate.
Good Neighbor reviews the window count, access, and requested scope before coordinating service. Adhesive removal, construction residue, specialty coatings, and repairs should not be presumed part of an ordinary glass-cleaning appointment.
Common questions
Should I remove curtains before the visit?
Ask first. The provider can explain what access is needed and whether removal or reinstallation is included. Heavy or delicate treatments may need separate handling.
Is stronger cleaner better for a stubborn mark?
No. Identify the surface and follow its care instructions. An incompatible product or abrasive tool may damage glass, film, or nearby finishes.
