Window Cleaning FAQs, answered by experts

The type of cleaning requested will change the total price you pay. Be sure to specify the type of cleaning you need when hiring a new cleaning service. Different approaches to cleaning change the price, such as:

  • Standard cleaning: $75–$175 per visit

  • Deep cleaning: $200–$400 per visit

  • Move-out cleaning: Up to $500

  • Event cleaning: $100–$500

To clean an estate, start by locating all important documents, which you’ll need to sort through. Have the mail forwarded, change the locks, and take inventory of the entire estate. Once you know what you’re dealing with, create a plan and a timeline for the cleanout. Start clearing out rooms and sorting items to donate, sell, or get rid of. Finally, deep clean the property.

Costs depend on window count, height, accessibility, labor, and whether interior and exterior cleaning is required.

Professionals remove dust, allergens, and stains while preserving fabric integrity and enhancing the appearance of window treatments.

Whether you tip before or after a carpet cleaning depends on when you’re available. If you’re home when they finish up, you can give them their tip after. However, if you need to leave before they’re done or if you won’t be home at all, you can prepare the tip beforehand and leave it for them in an envelope.
