Prepare the windows you will use when you return
Choose exterior-only or interior-and-exterior window cleaning. Identify patio-facing glass, sliding doors, screens, frames and tracks to include in the agreed quote. For interior work, arrange authorized entry and clear access to the glass.
Mention irrigation spots or recent renovation residue before service. Hard-water treatment and construction cleanup require separate assessment of glass condition, coatings, films, manufacturer care and residue. Routine cleaning does not guarantee every stain or deposit can be removed.
